From f955f1e15eb5f57783465d0fea7641592e4206e9 Mon Sep 17 00:00:00 2001 From: "Roy T. Fielding" Date: Mon, 4 Dec 2000 17:07:12 +0000 Subject: [PATCH] The httpd-2.0 repository is now open for business. I have copied over all files for which the cvs history is important. The rest can be added as new files (like this one). The modules were tagged as "moving_to_httpd_module" prior to my move. Any commits to apache-2.0 after that point will have to be repeated here. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@87174 13f79535-47bb-0310-9956-ffa450edef68 --- CHANGES | 8722 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 8722 insertions(+) create mode 100644 CHANGES diff --git a/CHANGES b/CHANGES new file mode 100644 index 0000000000..e27eab039b --- /dev/null +++ b/CHANGES @@ -0,0 +1,8722 @@ +Changes with Apache 2.0a9 + + *) Distribution directory structure reorganized to reflect a + normal source distribution with external install targets. + [Roy Fielding] + + *) The MPMs that need multiple segments of shared memory now create + two apr_shmem_t variables, one for each shared memory allocation. + the problem is that we can't determine how much memory will be required + for shared memory allocations once we try to allocate more than one + variable. The MM code automatically aligns the shared memory allocations, + so we end up needing to pad the amount of shared memory we want based + on how many variables will be allocated out of the shared memory segment. + It is just easier to create a second apr_shmem_t variable, and two + shmem memory blocks. + [Ryan Bloom] + + *) Cleanup the export list a bit. This creates a single unified list of + functions exported by APR. The export list is generated at configure + time, and that list is then used to generate the exports.c file. + Because of the way the export list is generated, we only export those + functions that are valid on the platform we are building on. + [Ryan Bloom] + + *) Enable logging the cookie with mod_log_config + [Sander van Zoest ] + + *) Fix a segfault in mod_info when it reaches the end of the configuration. + [Jeff Trawick] + + *) Added lib/aputil/ as a placeholder for utility functions which are not + specific to the Apache HTTP Server (but do not make sense with APR). + The first utility is "apu_dbm": a set of functions to work with DBM + files. This first version can be compiled for SDBM or GDBM databases. + [Greg Stein] + + *) Complete re-write of mod_include. This makes mod_include a filter that + uses buckets directly. This has now served the FAQ correctly. + [Paul Reder ] + + *) Allow modules to specify the first filter in a sub_request when + making the sub_request. This keeps modules from having to change the + output_filter immediately after creating the sub-request, and therefore + skip the sub_req_output_filter. [Ryan Bloom] + + *) Update ab to accept URLs with IPv6 literal address strings (in the + format described in RFC 2732), and to build Host header fields in + the same format. This allows IPv6 literal address strings to be + used with ab. This support has been tested against Apache 1.3 with + the KAME patch, but Apache 2.0 does not yet work with this format + of the Host header field. [Jeff Trawick] + + *) Accomodate an out-of-space condition in the piped logs and the + rotatelogs.c code, and no longer churn log processes for this + condition. [Victor J. Orlikowski] + + *) Add support for partial writes with apr_sendfile() to core_output_filter. + [Greg Ames] + +Changes with Apache 2.0a8 + + *) Add a directive to mod_mime so that filters can be associated with + a given mime-type. + [Ryan Bloom] + + *) Get multi-views working again. We were setting the path_info + field incorrectly if we couldn't find the specified file. + [Ryan Bloom] + + *) Fix 304 processing. The core should never try to send the headers + down the filter stack. Always, just setup the table in the request + record, and let the header filter convert it to data that is ready + for the network. + [Ryan Bloom] + + *) More fixes for the proxy. There are still bugs in the proxy code, + but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP) + successfully. + [Ryan Bloom] + + *) Fix params for apr_getaddrinfo() call in connect proxy handler. + [Chuck Murcko] + + *) APR: Add new apr_getopt_long function to handle long options. + [B. W. Fitzpatrick ] + + *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname. + Add generic apr_create_socket(). Add apr_getaddrinfo() for doing + hostname resolution/address string parsing and building + apr_sockaddr_t. Add apr_get_sockaddr() for getting the address + of one of the apr_sockaddr_t structures for a socket. Change + apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick] + + *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but + I have proxied pages with it, cleanup will commence soon. + [Ryan Bloom] + + *) Make the proxy work with filters. This isn't perfect, because we + aren't dealing with the headers properly. [Ryan Bloom] + + *) Do not send a content-length iff the C-L is 0 and this is a head + request. [Ryan Bloom] + + *) Make cgi-bin work as a regular directory when using mod_vhost_alias + with no VirtualScriptAlias directives. PR#6829 [Tony Finch] + + *) Remove BUFF from the PROXY connect handling. [Ryan Bloom] + + *) Get the default_handler to stop trying to deal with HEAD requests. + The idea is to let the content-length filter compute the C-L before + we try to send the data. If we can get the C-L correctly, then we + should send it in the HEAD response. + [Ryan Bloom] + + *) The Header filter can now determine if a body should be sent based + on r->header_only. The general idea of this is that if we delay + deciding to send the body, then we might be able to compute the + content-length correctly, which will help caching proxies to cache + our data better. Any handler that doesn't want to try to compute + the content-length can just send an EOS bucket without data and + everything will just work. + [Ryan Bloom] + + *) Add the referer to the error log if one is available. + [Markus Gyger ] + + *) Mod_info.c has now been ported to Apache 2.0. As a part of this + change, the root of the configuration tree has been exposed to modules + as ap_conftree. + [Ryan Morgan ] + + *) Get the core_output_filter to use the bucket interface directly. + This keeps us from calling the content-length filter multiple times + for a simple static request. + [Ryan Bloom] + + *) We are sending the content-type correctly now. + [Ryan Bloom and Will Rowe] + + *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report + a bogus bytes-sent value when the only thing being sent was trailers + and writev() returned an error (or EAGAIN). [Jeff Trawick] + + *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the + hints file to determine which platforms define + SINGLE_LISTEN_UNSERIALIZED_ACCEPT. + [Ryan Bloom] + + *) APR: add apr_get_home_directory() [Jeff Trawick] + + *) Initial import of 1.3-current mod_proxy. [Chuck Murcko] + + *) Not all platforms have INADDR_NONE defined by default. Apache + used to make this check and define INADDR_NONE if appropriate, + but APR needs the check too, and I suspect other applications will + as well. APR now defines APR_INADDR_NONE, which is always a valid + value on all platforms. + [Branko Èibej ] + + *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824. + [Shuichi Kitaguchi ] + + *) Relax the syntax checking of Host: headers in order to support + iDNS. PR#6635 [Tony Finch] + + *) When reading from file buckets we convert to an MMAP if it makes + sense. This also simplifies the default handler because the + default handler no longer needs to try to create MMAPs. + [Ryan Bloom] + + *) BUFF has been removed from the main server. The BUFF code will remain + in the code until it has been purged from the proxy module as well. + [Ryan Bloom] + + *) Byteranges have been completely re-written to be a filter. This + has been tested, and I believe it is working correctly, but it could + doesn't work for the Adobe Acrobat plug-in. The output almost matches + the output from 1.3, the only difference being that 1.3 includes + a content-length in the response, and this does not. + [Ryan Bloom] + + *) APR read/write functions and bucket read functions now operate + on unsigned integers, instead of signed ones. It doesn't make + any sense to use signed ints, because we return the error codes, + so if we have an error we should report 0 bytes read or written. + [Ryan Bloom] + + *) Always compute the content length, whether it is sent or not. + The reason for this, is that it allows us to correctly report + the bytes_sent when logging the request. This also simplifies + content-length filter a bit, and fixes the actual byte-reporing + code in mod_log_config.c + [Ryan Bloom] + + *) Remove AP_END_OF_BRIGADE definition. This does not signify what + it says, because it was only used by EOS and FLUSH buckets. Since + neither of those are required at the end of a brigade, this was + really signifying FLUSH_THE_DATA, but that can be determined better + by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH + buckets now return a length of 0, which is actually the amount of data + read, so they make more sense. + [Ryan Bloom] + + *) Allow the core_output_filter to save some data past the end of a + request. If we get an EOS bucket, we only send the data if it + makes sense to send it. This allows us to pipeline request + responses. As a part of this, we also need to allocate mmap + buckets out of the connection pool, not the request pool. This + allows the mmap to outlive the request. + [Ryan Bloom] + + *) Make blocking and non-blocking bucket reads work correctly for + sockets and pipes. These are the only bucket types that should + have non-blocking reads, because the other bucket types should + ALWAYS be able to return something immediately. + [Ryan Bloom] + + *) In the Apache/Win32 console window, accept Ctrl+C to stop the + server, but use Ctrl+Break to initiate a graceful restart + instead of duplicating behavior. [John Sterling] + + *) Patch mod_autoindex to set the Last-Modified header based on + the directory's mtime, and add the ETag header. [William Rowe] + + *) Merge the 1.3 patch to add support for logging query string in + such a way that "%m %U%q %H" is the same as "%r". + [Bill Stoddard] + + *) Port three log methods from mod_log_config 1.3 to 2.0: + CLF compliant '-' byte count, method and protocol. + [Bill Stoddard] + + *) Add a new LogFormat directive, %c, that will log connection + status at the end of the response as follows: + 'X' - connection aborted before the response completed. + '+' - connection may be kept-alive by the server. + '-' - connection will be closed by the server. + [Bill Stoddard] + + *) Expand APR for WinNT to fully accept and return utf-8 encoded + Unicode file names and paths for Win32, and tag the Content-Type + from mod_autoindex to reflect that charset if the the feature + macro APR_HAS_UNICODE_FS is true. [William Rowe] + + *) Compute the content length (and add appropriate header field) for + the response when no content length is available and we can't use + chunked encoding. [Jeff Trawick] + + *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK, + so that content input filters get dechunked data when using + the default handler. Also removed REQUEST_CHUNKED_PASS. + [Sascha Schumann] + + *) Add mod_ext_filter as an experimental module. This module allows + the administrator to use external programs as filters. Currently, + only filtering of output is supported. [Jeff Trawick] + + *) Most Apache functions work on EBCDIC machines again, as protocol + data is now translated (again). [Jeff Trawick] + + *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of + the EBCDIC support. They are noops on ASCII machines, so this + type of translation doesn't have to be surrounded by #ifdef + CHARSET_EBCDIC. [Jeff Trawick] + + *) Fix mod_include. tag commands work again, and the server will + send the FAQ again. This also allows mod_include to set aside + buckets that include partial buckets. + [Ryan Bloom and David Reid] + + *) Add suexec support back. [Manoj Kasichainula] + + *) Lingering close now uses the socket directly instead of using + BUFF. This has been tested, but since all we can tell is that it + doesn't fail, this needs to be really hacked on. + [Ryan Bloom] + + *) Allow filters to modify headers and have those headers be sent to + the client. The idea is that we have an http_header filter that + actually sends the headers to the network. This removes the need + for the BUFF to send headers. + [Ryan Bloom] + + *) Charset translation: mod_charset_lite handles translation of + request bodies. Get rid of the xlate version of ap_md5_digest() + since we don't compute digests of filtered (e.g., translated) + response bodies this way anymore. (Note that we don't do it at + all at the present; somebody needs to write a filter to do so.) + [Jeff Trawick] + + *) Input filters and ap_get_brigade() now have a input mode parameter + (blocking, non-blocking, peek) instead of a length parameter. + [hackathon] + + *) Update the mime.types file to the registered media types as + of 2000-10-19. PR#6613 [Carsten Klapp , + Tony Finch] + + *) Namespace protect some macros declared in ap_config.h + [Ryan Bloom] + + *) Support HTTP header line folding with input filtering. + [Greg Ames] + + *) Mod_include works again. This should still be re-written, but at + least now we can serve an SHTML page again. + [Ryan Bloom] + + *) Begin to remove BUFF from the core. Currently, we keep a pointer + to both the BUFF and the socket in the conn_rec. Functions that + want to use the BUFF can, functions that want to use the socket, + can. They point to the same place. + [Ryan Bloom] + + *) apr_psprintf doesn't understand %lld as a format. Make it %ld. + [Tomas "Ögren" ] + + *) APR pipes on Unix and Win32 are now cleaned up automatically when the + associated pool goes away. (APR pipes on OS/2 were already had this + logic.) This resolvs a fatal file descriptor leak with CGIs. + [Jeff Trawick] + + *) The final line of the config file was not being read if there was + no \n at the end of it. This was caused by apr_fgets returning + APR_EOF even though we had read valid data. This is solved by + making cfg_getline check the buff that was returned from apr_fgets. + If apr_fgets return APR_EOF, but there was data in the buf, then we + return the buf, otherwise we return NULL. + [Ryan Bloom] + + *) Piped logs work again in the 2.0 series. + [Ryan Bloom] + + *) Restore functionality broken by the mod_rewrite security fix: + rewrite map lookup keys and default values are now expanded + so that the lookup can depend on the requested URI etc. + PR #6671 [Tony Finch] + + *) Tighten up the syntax checking of Host: headers to fix a + security bug in some mass virtual hosting configurations + that can allow a remote attacker to retrieve some files + on the system that should be inaccessible. [Tony Finch] + + *) Add a pool bucket type. This bucket is used for data allocated out + of a pool. If the pool is cleaned before the bucket is destroyed, then + the data is converted to a heap bucket, allowing it to survive the + death of the pool. + [Ryan Bloom] + + *) Add a flush bucket. This allows modules to signal that the filters + should all flush whatever data they currently have. There is no way + to actually force them to do this, so if a filter ignores this bucket, + that's life, but at least we can try with this. + [Ryan Bloom] + + *) Add an output filter for sub-requests. This filter just strips the + EOS bucket so that we don't confuse the main request's core output + filter by sending multiple EOS buckets. This change also makes sub + requests start to send EOS buckets when they are finished. + [Ryan Bloom] + + *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also + makes ap_bucket_destroy a return void, which is okay because it + used to always return APR_SUCCESS, and nobody ever checked its + return value anyway. + [Cliff Woolley ] + + *) Remove the index into the bucket-type table from the buckets + structure. This has now been replaced with a pointer to the + bucket_type. Also add some macros to test the bucket-type. + [Ryan Bloom] + + *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols + for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper) + and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE. + All _VAR_ flavors changes to _DATA to be absolutely clear. + [William Rowe] + + *) Add support for /, //, //servername and //server/sharename + parsing of blocks under Win32 and OS2. + [Tim Costello, William Rowe, Brian Harvard] + + *) Remove the function pointers from the ap_bucket type. They have been + replaced with a global table. Modules are allowed to register bucket + types and use then use those buckets. + [Ryan Bloom] + + *) mod_cgid: In the handler, shut down the Unix socket (only for write) + once we finish writing the request body to the cgi child process; + otherwise, the client doesn't hit EOF on stdin. Small request bodies + worked without this change (for reasons I don't understand), but large + ones didn't. [Jeff Trawick] + + *) Remove file bucket specific information from the ap_bucket type. + This has been moved to a file_bucket specific type that hangs off + the data pointer in the ap_bucket type. + [Ryan Bloom] + + *) Input filtering now has a third argument. This is the amount of data + to read from lower filters. This argument can be -1, 0, or a positive + number. -1 means give me all the data you have, I'll deal with it and + let you know if I need more. 0 means give me one line and one line + only. A positive number means I want no more than this much data. + + Currently, only 0 and a positive number are implemented. This allows + us to remove the remaining field from the conn_rec structure, which + has also been done. + [Ryan Bloom] + + *) Big cleanup of the input filtering. The goal is that http_filter + understands two conditions, headers and body. It knows where it is + based on c->remaining. If c->remaining is 0, then we are in headers, + and http_filter returns a line at a time. If it is not 0, then we are + in body, and http_filter returns raw data, but only up to c->remaining + bytes. It can return less, but never more. + [Greg Ames, Ryan Bloom, Jeff Trawick] + + *) mod_cgi: Write all of the request body to the child, not just what + the kernel would accept on the first write. [Jeff Trawick] + + *) Back out the change that moved the brigade from the core_output_filters + ctx to the conn_rec. Since all requests over a given connection + go through the same core_output_filter, the ctx pointer has the + correct lifetime. + [Ryan Bloom] + + *) Fix another bug in the send_the_file() read/write loop. A partial + send by apr_send would cause unsent data in the read buffer to + get clobbered. Complete making send_the_file handle partial + writes to the network. + [Bill Stoddard] + + *) Fix a couple of type fixes to allow compilation on AIX again + [Victor J. Orlikowski ] + + *) Fix bug in send_the_file() which causes offset to be ignored + if there are no headers to send. + [Bill Stoddard] + + *) Handle APR_ENOTIMPL returned from apr_sendfile in the core + filter. Useful for supporting Windows 9* with a binary + compiled on Windows NT. + [Bill Stoddard] + +Changes with Apache 2.0a7 + + *) Reimplement core_output_filter to buffer/save bucket brigades + across multiple calls to the core_filter. The brigade will be + sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE + thresholds are hit or the EOS bucket is received. + [Bill Stoddard] + + *) Create experimental filter (buffer_filter) that coalesces bytes + into one large buffer before invoking the next filter in the + chain. This filter is particularly useful with the current + implementation of mod_autoindex when it inserted above the + chunk_filter. mod_autoindex generates a lot of brigades that + containing buckets holding just a few bytes each. The + buffer_filter coalesces these buckets into a single large bucket. + [Bill Stoddard] + + *) Add apr_sendfile() support into the core_output_filter. + [Bill Stoddard] + + *) Add apr_sendv() support into the core_output_filter. + [Bill Stoddard] + + *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS + [Mike Abbott ] + + *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't + make much sense, because Apache uses buckets instead of BUFFs now. + [Ryan Bloom] + + *) send_the_file now falls back to a read/write loop on platforms that + do not have sendfile. + [Ryan Bloom and Brian Havard] + + *) Install apachectl correctly, and substitute the proper values so + that it works again. [Ryan Bloom] + + *) Better(??) handle platforms that lack sendfile(). + [Jim Jagielski] + + *) APR now has UUID generation/formatting/parsing support. + [Greg Stein] + + *) Begin the http_filter. This is an input filter that understands + the absolute basic amount required to parse an HTTP Request. The + goal is to be able to split headers from request body before passing + the data back to the other filters. + [Ryan Bloom] + + *) Bring forward from 1.3.13 the config directory implementation + [Jim Jagielski] + + *) install apxs if it is created + [Ryan Bloom] + + *) Added APR_IS_STATUS_condition test macros to eliminate canonical error + conversions. [William Rowe] + + *) Now that we have ap_add_input_filter(), rename ap_add_filter() to + ap_add_output_filter(). [Jeff Trawick] + + *) Multiple build and configuration fixes + Build process: + + -add datadir and localstatedir substitutions + -fix layout name + -fix logfilename misspelling + -fix evaluation of installation dir variables and + -replace $foobar by $(foobar) to be usefull in the makefile + + Cross compile: + + -add rules for cross-compiling in rules.mk. Okay, rule to check for + $CC_FOR_BUILD is still missing + -use CHECK_TOOL instead of CHECK_PROG for ranlib + -add missing "AR=@AR@" to severaly Makefile.in's + -cache result for "struct rlimit" + -compile all helper programs with native and cross compiler + and use the native version to generate header file + ["Rüdiger" Kuhlmann ] + + *) Prepare our autoconf setup for autoconf 2.14a and for cross- + compiling. + ["Rüdiger" Kuhlmann ] + + *) Fix a bug where a client which only sends \n to delimit header + lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED + message. Start working on ebcdic co-existance with input + filtering. + [William Rowe, Greg Ames] + + *) If mod_so is enabled in the server always create libexec, even + if there are no modules installed in this directory. This is a + requirement for APXS to work correctly. + [Ryan Bloom] + + *) Connection oriented output filters are now stored in the + conn_rec instead of the request_rec. This allows us to add the + output filter in the pre-connection phase instead of the + post_read_request phase, which keeps us from trying to write an + error page before we have a filter to write to the network. + [Ryan Bloom, Jeff Trawick, and Greg Ames] + + *) Cleaning up an mmap bucket no longer deletes the mmap. An + mmap can be used across multiple buckets (default_handler with + byte ranges, mod_file_cache, mod_mmap_static), so cleanup of + the mmap itself can't be associated with the bucket. + [Jeff Trawick] + + *) Add .dll caching directive ISAPICacheFile to mod_isapi. + [William Rowe] + + *) Radical surgery to improve mod_isapi support under Win32. + Includes a number of newer ServerSupportFunction calls, support + for ReadClient (in order to retrieve POSTs greater than 48KB), + and general bug fixes to more reliably load ISAPI .dll's and + prevent leaking handle resources. Note: There are still + discrepancies between IIS's and Apache's ServerVariables, and + async calls are still not supported. Additional warnings are + logged to facilitate debugging of unsupported ISAPI calls. + [William Rowe] + + *) Add input filtering to Apache. The basic idea for the input + filters is the same as the ideas for output filters. The biggest + difference is that instead of calling ap_pass_brigade, ap_get_brigade + should be called, and the order of execution for the filter itself is + different. When writing an output filter, a brigade is passed in, + and filters operate directly on that brigade, when done, they call + ap_pass_brigade. Input filters are the exact opposite. Because input + is not a push operation, filters first call ap_get_brigade. When this + function returns, the input filter will be left with a valid brigade. + The input filter should then operate on the brigade, and return. + [Ryan Bloom] + + *) Fix building on BSD/OS using its native make. The build system + falls back to the BSD .include directive on that host platform. + [Sascha Schumann] + + *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5, + SHA1 and plaintext password encodings. Make feature tests a + bit more flexible. [William Rowe] + + *) Charset translation: mod_charset_lite handles output content + translation in a filter. mod_charset_lite no longer ignores + subrequests. A bunch of cruft related to BUFF's support for + translating request and response bodies was removed. + [Jeff Trawick] + + *) Move the addition of the CORE filter to the post_read_request + hook in http_core.c. This removes the need to add the filter in + multiple places and allows for an SSL module to be added much + simpler. [Ryan Bloom] + + *) Fix a security problem that affects certain configurations of + mod_rewrite. If the result of a RewriteRule is a filename that + contains expansion specifiers, especially regexp backreferences + $0..$9 and %0..%9, then it may be possible for an attacker to + access any file on the web server. [Tony Finch] + + *) Fix a bug where errors that are detected during early request parsing + don't produce visible HTTP error messages at the browser, because + the core_filter wasn't present. [Greg Ames] + + *) Provide apr_socklen_t as a portability aid. + [Victor J. Orlikowski] + + *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2) + as well as a comment arg to the add, adduser and update cmds. + update allows the user to clear or preserve pw/groups/comment. + Fixed a bug in dbmmanage that prevented the check option from + parsing a password followed by :group... text. Corrected the + seed calcualation for Win32 systems, and added -lsdbm support. + [William Rowe] + + *) Configured mod_auth_dbm to compile with sdbmlib under Win32. + [William Rowe] + + *) Avoid a segfault when parsing .htaccess files. An + uninitialized tree pointer was passed to ap_build_config(). + [Jeff Trawick] + + *) Change the way that inet_addr & inet_network are checked for + in APR's configure process to allow BeOS BONE to correctly + find them. With this change BeOS BONE now builds from source + with no problems. [David Reid] + + *) Fix a bug in apr_create_process() for Unix. The NULL signifying + the end of the parameters to execve() was stored in the wrong + location, overlaying the storage beyond the newargs[] array and + also passing uninitialized storage to execve(), which would + sometimes fail with EFAULT. [Jeff Trawick] + + *) Fix a bug parsing configuration file containers. With a sequence + like this in the config file + + + any stuff + + + (blank line) + any stuff + + + the second container would be terminated at the blank line due to + sediment in the buffer from reading the prior and an + error message would be generated for the real for the + second container. Also due to this problem, any two characters + could be used for "] + + *) Fix chunking problem with CGI scripts. The general problem was that + the CGI modules were adding an EOS bucket and then the core added an + EOS bucket. The chunking filter finalizes the chunked response when it + encounters an EOS bucket. Because two EOS buckets were sent, we + finalized the response twice. The fix is to make sure we only send one + EOS, by utilizing a flag in the request_rec. + [Ryan Bloom] + + *) apr_put_os_file() now sets up the unget byte appropriately on Unix + and Win32. Previously, the first read from an apr_file_t set up via + apr_put_os_file() would return a '\0'. [Jeff Trawick] + + *) Mod_cgid now creates a single element bucket brigade, with a pipe + bucket, instead of using BUFF's and ap_r*. + [Ryan Bloom] + + *) APRVARS.in no longer overwrites the EXTRA_LIBS variable. + [Mike Abbott ] + + *) Remove ap_bopenf from buff code. This required modifying the file_cache + code to use APR file's directly instead of going through BUFFs. + [Ryan Bloom] + + *) Fix compile break on some platforms for mod_mime_magic.c + [John K. Sterling ] + + *) Fix merging of AddDefaultCharset directive. + PR #5872 (1.3) [Jun Kuriyama ] + + *) Minor revamp of the rlimit sections of code. We now test + explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit() + is now "available" even if the platform doesn't support + the rlimit family (it's just a noop though). [Jim Jagielski] + + *) Migrate the pre-selection of which MPM to use for specific + platforms to hints.m4, which contains (or should contain) + all platform specific "hints". [Jim Jagielski] + + *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary + [Ryan Bloom] + + *) Add tables with non-string/binary values to APR. + [Ken Coar] + + *) Fix some bad calls to ap_log_rerror() in mod_rewrite. + [Jeff Trawick] + + *) Update PCRE to version 3.2. [Ryan Bloom] + + *) Change the way buckets' destroy functions are called so that + they can be more directly used when changing the type of a + bucket in place. [Tony Finch] + + *) Add generic support for reference-counting the resources used by + buckets, and alter the HEAP and MMAP buckets to use it. Change + the way buckets are initialised to support changing the type of + buckets in place, and use it when setting aside TRANSIENT buckets. + Change the implementation of TRANSIENT buckets so that it can be + mostly shared with IMMORTAL buckets, which are now implemented. + [Tony Finch] + +Changes with Apache 2.0a6 + + *) Add support to Apache and APR for dsos on OS/390. [Greg Ames] + + *) Add a chunking filter to Apache. This brings us one step closer + to removing BUFF. [Ryan Bloom] + + *) ap_add_filter now adds filters in a LIFO fashion. The first filter + added to the stack is the last filter to be called. [Ryan Bloom] + + *) Apache 2.0 has been completely documented using Scandoc. The + docs can be generated by running 'make docs'. [Ryan Bloom] + + *) Add filtered I/O to Apache. This is based on bucket brigades, + Currently the buckets still use BUFF under the covers, but that + should change quickly. The only currently written filter is the + core filter which just calls ap_bwrite. [The Apache Group] + + *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't + built with thread support. [Jeff Trawick] + + *) Abort configuration if --with-layout was specified and there's + no layout definition file. [Ken Coar] + + *) Add support for '--with-port=n' option to configure. [Ken Coar] + + *) Add support for extension methods for the Allow response header + field, and an API routine for accessing r->allowed and the + list of extension methods in a unified manner. [Ken Coar] + + *) mod_cern_meta: fix broken file reading loop in scan_meta_file(). + [Rob Simonson ] + + *) Get xlate builds working again. The apr renaming in 2.0a5 broke + APACHE_XLATE builds. [Jeff Trawick] + + *) A configuration file parsing problem was fixed. When the + configuration file started with an IfModule/IfDefine container, + only the last statement in the container would be retained. + [Jeff Trawick] + +Changes with Apache 2.0a5 + + *) Perchild is serving pages after passing them to different child + processes. There are still a lot of bugs, but this does work. I + have made requests against the same installation of Apache, and had + different servers use different user IDs to serve the responses. + This change moves to using socketpair instead of an AF_UNIX socket. + [Ryan Bloom] + + *) Perchild MPM still doesn't work perfectly, but it is serving pages. + It can't seem to pass between child processes yet, but I think we + are closer now than before. This moves us back to using Unix + Domain Sockets. [Ryan Bloom] + + *) libapr functions and types renamed with apr_ prefix. + #include "apr_compat.h" for 1.3.x backwards compat + [Perl] + + *) Fix problems with APR sockaddr handling on Win32. It didn't always + return the right information on the local socket address. + [Gregory Nicholls ] + + *) ap_recv() on Win32: Set bytes-read to 0 on error. + [Gregory Nicholls ] + + *) Add an option to not detach from the controlling terminal without + going into single process mode. This allows for much easier + debugging of the process startup code. [Ryan Bloom] + + *) ab: don't use perror() to report the failure of an APR function. + [Jeff Trawick] + + *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the + scoreboard on graceful restarts. + [Ryan Bloom] + + *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c. + An invalid ap_proc_t was passed to ap_create_process(). + [Jeff Trawick] + + *) Allow modules to register filters. Those filters are still + never called, but this is a step in the right direction. + [Ryan Bloom and Greg Stein] + + *) Register the mod_cgid daemon process for cleanup so that it is + killed at termination if it does not die when the parent gets + SIGTERM. This change is to fix occasional problems where the + process stays around. Bugs in similar logic in mod_rewrite and + mod_include were also fixed. [Jeff Trawick] + + *) Fix a bug in the time handling. Basically, we were imploding a time + in ap_parseHTTPdate, but it had bogus data in the exploded time format. + Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time + uses those two fields to adjust the time value. Because of the HTTP + spec, both of those values can be zero'ed out safely. This fixes + the bug correctly. [Ryan Bloom] + + *) Fix a couple of place in the Windows code where the wrong error + code was being returned. [Gregory Nicholls ] + + *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet] + + *) Added the APR_EOL_STR macro for platform dependent differences in + logfiles and other raw text (such as all APR files). Fixes logfiles + not terminated with cr/lf sequences in Win32. [William Rowe] + + *) Move all strings functions in APR to src/lib/apr/strings and create + apr_strings.h for the prototypes. [Ryan Bloom] + + *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure + to repeat the syscall until we stop getting EINTR. I noticed a + related problem at termination (SIGTERM) on FreeBSD when using + fcntl(). Apache 1.3 had these new loops too. Also, make the flock() + implementation work properly with child init. Previously, ap_lock() + was essentially a no-op because all children were using different + locks and thus nobody ever blocked. [Jeff Trawick] + + *) The htdocs/ tree has been moved out of the CVS source tree into + a separate area for easier development. This has NO EFFECT on + end-users or Apache installations. [Ken Coar] + + *) Integrate the mod_dav module for WebDAV protocol handling. This + adds the dav and dav_fs modules, the SDBM library, and additional + XML handling utilities. [Greg Stein] + + *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes + [Greg Stein] + + *) Update the lib/expat-lite/ library (bring forward changes from + the Apache 1.3 repository). [Greg Stein] + + *) If sizeof(long long) == sizeof(long), then prefer long in APR + configure.in. [Dave Hill ] + + *) Add ap_sendfile for Tru64 Unix. Also, add an error message for + machines where sendfile is detected, but nobody has written ap_sendfile. + [Dave Hill ] + + *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski] + + *) ab would start up more connections than needed, then quit when the + desired number were finished. Also fixed a logic error involving + ab keepalives. [Victor J. Orlikowski] + + *) WinNT: Implement non-blocking pipes with timeouts to communicate + with CGIs. Apache 2.0a4 had non-blocking pipes but without + timeouts (i.e, if a timeout was specified, the pipe reverted to + a full blocking pipe). Now the behaviour is more in line with + Unix non-blocking pipes. + [Bill Stoddard] + + *) WinNT: Implement accept socket reuse. Using mod_file_cache to + cache open file handles along with accept socket reuse enables + Apache 2.0 to serve non-keepalive requests for static files at + 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps + and Apache 2.0 will serve almost 1200 rps on my system). + [Bill Stoddard] + + *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache + supports two config directives, mmapfile (same behavious as + mod_mmap_static) and cachefile. Use the cachefile directive + to cache open file handles. This directive only works on systems + that have implemented the ap_sendfile API. cachefile works today + on Windows NT, but has not been tested on any flavors of Unix. + [Bill Stoddard] + + *) Cleanup the configuration. With the last few changes the + configuration process automatically: + inherits information about how to build from APR. Allowing + APR to inform Apache that it should or should not use -ldl + + Detects which mod_cgi should be used mod_cgi or mod_cgid, + based on the threading model + + Apache calls APR's configure process before finishing it's + configuration processing, allowing for more information flow + between the two. + [Ryan Bloom] + + + *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK + with non-zero argument makes the socket non-blocking. BeOS and + OS/2 already worked this way. [Jeff Trawick] + + *) ap_close() now calls ap_flush() for buffered files, so write + operations work a whole lot better on buffered files. + [Jeff Trawick] + + *) Fix error messages issued from MPMs which explain where to change + compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads). + [Greg Ames] + + *) ap_create_pipe() now leaves pipes in blocking state. (This helps + reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is + now the way that the blocking state of a pipe is manipulated. + ap_block_pipe() is gone. [Jeff Trawick] + + *) Correct the problem where the only local host name that the IP stack + can discover are 'undotted' private names. If no fully qualified + domain name can be identified, the default ServerName will be set to + the machine's IP address string. A warning is always provided if the + ServerName not specified, but assumed. Solves PR6215 [William Rowe] + + *) Repair problems with config file processing which caused segfault + at init when virtual hosts were defined and which caused ServerName to + be ignored when there was no valid DNS setup. [Jeff Trawick] + + *) Removed pointless ap_is_aborted macro function. [Roy Fielding] + + *) Add ap_sendfile implementation for AIX + [Victor J. Orlikowski] + + *) Repair C++ compatibility in ap_config.h, apr_file_io.h, + apr_network_io.h, and apr_thread_proc.h. + [Tyler J. Brooks , Jeff Trawick] + + *) Bring the allocation and pool debugging code back into a working + state. This will need to be tested as so far it's only been used on + BeOS. [David Reid] + + *) Change configuration command setup to be properly typesafe when in + maintainer mode. Note that this requires a compiler that can initialise + unions. [Ben Laurie] + + *) Turn on buffering for config file reads. Part of this was to + repair buffered I/O support in Unix and implement buffered + ap_fgets() for all platforms. [Brian Havard, Jeff Trawick] + + *) Win32: Fix problem where UTC offset was not being set correctly + in the access log. Problem reported on news group by Jerry Baker. + [Bill Stoddard] + + *) Fix segfault when reporting this type of syntax error: + " without matching section", where + container is VirtualHost or Directory or whatever. + [Jeff Trawick] + + *) Prevent the source code for CGIs from being revealed when using + mod_vhost_alias and the CGI directory is under the document root + and a user makes a request like http://www.example.com//cgi-bin/cgi + as reported in + [Tony Finch] + + *) Add support for the new Beos NetwOrking Environment (BONE) + [David Reid] + + *) xlate: ap_xlate_conv_buffer() now tells the caller when the + final input char is incomplete; ap_bwrite_xlate() now handles + incomplete final input chars. [Jeff Trawick] + + *) Yet another update to saferead/halfduplex stuff -- need to ensure + that a bhalfduplex call occurs before logging or else DNS and + such can delay the last packet of the response. [Dean Gaudet] + + *) Some syscall reduction in APR on unix -- don't seek when setting + up an mmap; and don't fcntl() more than once per socket. + [Dean Gaudet] + + *) When mod_cgid is started as root, the cgi daemon now switches + to the configured User/Group (like other httpd processes) + instead of continuing as root. [Jeff Trawick] + + *) The prefork MPM now uses an APR lock for the accept() mutex. + It has not been getting a lock at all recently. httpd -V now + displays APR's selection of the lock mechanism instead of the + symbols previously respected by prefork. [Jeff Trawick] + + *) Change the mmap() feature test to check only for existence. + The previous check required features not used by Apache. + [Greg Ames] + + *) Fix a couple of bugs in mod_cgid: The cgi arguments were + sometimes mangled. The len parm to accept() was not + initialized, leading sometimes to an endless loop of failed + accept() calls on OS/390 and anywhere else that failed the call + if the len was negative. Use for struct sockaddr_un + instead of declaring it ourselves to fix a compilation problem + on Solaris. [Jeff Trawick] + + *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom] + + *) Fix zombie process problem with mod_cgi. [Jeff Trawick] + + *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames] + + *) Fix storage overlay when loading dsos. Symptom: Apache dies at + initialization if ALLOC_DEBUG is defined; no known symptom + otherwise. [Jeff Trawick] + + *) Fix typo in configure script when checking for mod_so. bash + doesn't seem to have a problem but /bin/sh on Solaris does. + Symptom: "./configure: test: unknown operator ==" + [Jeff Trawick] + + *) Rebind the Win32 NT and 9x services control into the MPM. + All console, WinNT SCM and Win9x pseudo-service control code is + now wrapped within the WinNT MPM. + [William Rowe] + + *) Make a copy of getenv("PATH") before storing for later use. Some + getenv() implementations use the same storage for successive calls. + CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick] + + *) Server Tokens work in 2.0 again. This also propogates the change + to allow just the product name in the server string using + PRODUCT_ONLY. + [Ryan Bloom] + +Changes with Apache 2.0a4 + + *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers + won't need to call it. [Greg Ames, Jeff Trawick] + + *) Move pre_config hook call to between configuration read and config + tree walk. This allows all modules to implement pre_config hooks + and know that they will be called at an appropriate time. + [Ryan Bloom] + + *) mod_cgi, mod_cgid: Make ScriptLog directive work again. + [Jeff Trawick] + + *) Add pre-config hooks back to all modules. + [Ryan Bloom] + + *) Fix a SIGSEGV in ap_md5digest(), which is used when you have + ContentDigest enabled and we can't/don't mmap the file. + [Jeff Trawick] + + *) We now report the correct line number for syntax errors in config + files. [Ryan Bloom, Greg Stein, Jeff Trawick] + + *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t- + related bugs, and changed shmem/locking to use apr API. Shared-mem + is currently disabled, however, because of problems with graceful + restarts. [Ronald Tschalär] + + *) Fix corruption of IFS variable in --with-module= handling. + Depending on the user's shell or customization thereof, there + would be errors generating ap_config_auto.h later in the configure + procedure. [Jeff Trawick] + + *) mod_cgi: Restore logging of stderr from child process when ScriptLog + isn't used (as in 1.3), except that on Unix it is now logged via + ap_log_rerror() instead of by the child having STDERR_FILENO refer + to the error log. [Greg Ames, Jeff Trawick] + + *) Add '-D' argument processing for run time configuration defines. + [William Rowe] + + *) Organize http_main.c as independent code, such that no code or + global data is exported from it. WIN32 will dynamically link it + to the server core, so this will prevent mutual dependency. + [William Rowe] + + *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD() + and APR_VAR_EXPORT to correctly resolve apr functions and globals. + [William Rowe] + + *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers. + [William Rowe, Jan Just Keijser ] + + *) Add mod_charset_lite for configuring character set translation. + [Jeff Trawick] + + *) Add '-n' option to htpasswd to make it print its user:pw record + on stdout rather than having to frob a text file. [Ken Coar] + + *) Fix saferead. Basically, we flush the output buffer if a read on the + input will block. + [Ryan Bloom] + + *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not + a conversion is single-byte only. [Jeff Trawick] + + *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that + the BeOS 5.0 documentation says that shutdown doesn't work yet. + [Roy Fielding] + + *) Fix some minor errors where pid was being manipulated as an int + instead of the portable pid_t. [Roy Fielding] + + *) Fix some error log prints that were printing the pointer to a + structure rather than the pid within the structure. + [Jeff Trawick, Roy Fielding] + + *) ab: Fix a command-line processing bug; track bad headers in + err_response; support reading headers up to 2K. + [Ask Bjoern Hansen ] + + *) Fix ap_resolve_env() so that it handles new function added in a prior + alpha (see "Added the capability to do ${ENVVAR} constructs in the + config file.") as well as the constructs used by mod_rewrite. + [Paul Reder ] + + *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames] + + *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use + APR to perform translation, instead of accessing the hard-coded tables + in 1.3's ebcdic.c. [Jeff Trawick] + + *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing. + [Jeff Trawick] + + *) Add the ability to hook into the config file reading phase. Basically + if a directive is specified EXEC_ON_READ, then when that directive is + read from the config file, the assocaited function is executed. This + should only be used for those directives that must muck with HOW the + server INTERPRETS the config. This should not be used for directives + that re-order or replace items in the config tree. Those changes should + be made in the pre-config step. + [Ryan Bloom] + + *) Add mod_example to the build system. + [Tony Finch] + + *) APR: Add ap_xlate_conv_byte() to convert one char between single- + byte character sets. [Jeff Trawick] + + *) Pick up various EBCDIC fixes from 1.3 (from Martin + Kraemer and Oliver Reh originally according to the change log). + [Jeff Trawick] + + *) Fix a couple of problems in RFC1413 support (controlled by the + IdentityCheck directive). Apache did not build the request string + properly and more importantly Apache would loop forever if the + would-be ident server dropped the connection before sending a + properly terminated response. [Jeff Trawick] + + *) apxs works in 2.0. + [Ryan Bloom] + + *) Reliable piped logs work in 2.0. + [Ryan Bloom] + + *) Introduce a hash table implementation into APR to be used for + replacing tables and other random data structures in Apache. + [Tony Finch] + + *) Add some more error reporting to htpasswd in the case of problems + generating or accessing the temporary file. Also, pass in a + buffer if the implementation knows how to use it (i.e., if L_tmpnam + is defined). [Ken Coar] + + *) Configure creates config.nice now containing your configure + options. Syntax: ./config.nice [--more-options] + [Sascha Schumann] + + *) Fix various return code problems in APR on Win32. For most of + these, APR was returning APR_EEXIST instead of GetLastError()/ + WSAGetLastError(). [Jeff Trawick] + + *) Make piped logs work again in version 2.0 + [Ryan Bloom] + + *) Add VPATH support to UNIX build system of Apache and APR. + [Sascha Schumann] + + *) Fix ap_tokenize_to_argv to respect the const arguments that are + passed to it. + [Ryan Bloom] + + *) Fix mm's memcpy/memset macros, pointer arithmetic was broken. + Patch submitted to author. + [Sascha Schumann] + + *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require + /sbin in PATH on FreeBSD (all submitted to rse previously) + [Jeff Trawick] + + *) Fix building Pthread-based MPMs on OpenBSD + [Sascha Schumann] PR#26 + + *) Fix ap_readdir() problem on systems where d_name[] field in + struct dirent is declared with only one byte. (This problem only + affected multithreaded builds.) This caused a segfault during + pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at + least). [Jeff Trawick] + + *) Fix some make-portability problems on at least Tru64, Irix + and UnixWare. + [Sascha Schumann] PR#18, PR#39 + + *) Add ap_sigwait() to support old-style sigwait() on systems + like OS/390 and UnixWare. + [Sascha Schumann] + + *) Add POSIX-thread flags for more platforms. + [Sascha Schumann] + + *) Fix some minor bugs in ap_strerror(). Teach ap_strerror() + (on Unix, at least) to handle resolver errors. Fix a bug in + the definition of APR_ENOMEM so that ap_strerror() can spit + out the correct error message for it. + [Jeff Trawick] + +Changes with Apache 2.0a3 + + *) mod_so reports ap_os_dso_error() if ap_dso_load() fails + [Doug MacEachern] + + *) API: *HOOK* macros now have an AP_ prefix + [Doug MacEachern] + + *) Win32: Eliminate redundant calls to initialize winsock. + [Tim Costello ] + + *) Fix bugs initializing ungetchar for pipes. + [Chia-liang Kao ] + + *) The ab program in the src/support directory is now portable using + APR. + [Ryan Bloom] + + *) Support directory is being compiled when the server is built + [Ryan Bloom] + + *) The configure option --with-program-name has been added to allow + developers to rename the executable at configure time. This also + changes the name of the config files to match the executable's name. + [Ryan Bloom] + + *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames + containing version numbers. [Martin Pool] + + *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on + Unix; access_log and error_log now created with these perms; non- + Unix is unaffected [Jeff Trawick] + + *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h. + Replaced more magic numbers with MD5_DIGESTSIZE. + [William Rowe, Roy Fielding] + + *) Win32: Get mod_auth_digest compiling and added to the Windows + build environment. Not tested and I'd be suprised if it + actually works. [Bill Stoddard] + + *) Revamp the Win32 make environment. Makefiles have been removed and + Apache.dsw created to bring together all the pieces. Create new file + os/win32/BaseAddr.ref to define module base addresses (to prevent + dll relocation at start-up). + [William Rowe, Greg Marr, Tim Costello, Bill Stoddard] + + *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most + of the \015, \012, and \015\012 constants with macros. + [Greg Ames ] + + *) Add ap_xlate_open() et al for translation of text between different + character sets. The initial implementation requires iconv(). + [Jeff Trawick] + + *) More FAQs and answers from comp.infosystems.www.servers.unix. + [Joshua Slive ] + + *) CGI output is being timed out now. + [Ryan Bloom] + + *) Fix the problem with dieing quietly. dupfile now takes a pool which + is used by the new apr file. There is no reason to create a new file + with the same lifetime as the original file. + [Ryan Bloom] + + *) Win32: Attempt to eliminate dll relocation at start-up by specifying + module base addresses. This will help shooting seg faults + in the field. [William Rowe ] + + *) Update Apache on Windows documentation. Add new document + describing how to compile Apache on Windows. + [William Rowe ] + + *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take + microseconds instead of seconds. Some storage leaks and other + minor bugs in related code were fixed. [Jeff Trawick] + + *) Win32: First cut at getting mod_isapi working under 2.0 + [William Rowe ] + + *) First stab at getting mod_auth_digest working under 2.0 + quick change summary: + - moved the random byte generation (ap_generate_random_bytes) into APR + - now uses ap_time_t + - compiles and runs on linux + - tested with amaya + [Brian Martin ] + + *) Win32: Move the space stripping of physical service names + fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an + unresolved symbol. Add dependency checking to the + CreateService call to ensure TCPIP and AFP (winsock) is started + before Apache. + [William Rowe ] + + *) Win32: Add code to perform latebinding on functions that may + not exist on all levels of Windows where Apache runs.

At this point, the server will not compile on Windows because + of the recent DSO commits. Fixing those next. + [Bill Rowe & Bill Stoddard] + + *) Added error checking for file I/O APR routines. + [Jon Travis ] + + *) APR: Don't use the values of resolver error codes for the + corresponding APR error codes.

[Jim Jagielski] + + *) Added the capability to do ${ENVVAR} constructs in the + config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited + it does this on a line by line basis; i.e. if the envvar + expands to something with spaces you have to protect it + by adding quotes around it (Unless of course you expect it + to contains more than one argument. Alternatively you + can compile it on a per token basis; which is what people + usually expect by setting RESOLVE_ENV_PER_TOKEN. But this + hampers fancier hacks. + [Dirk-Willem van Gulik] + + *) Changed the 'ErrorDocument' syntax in that it NO longer + supports the asymetric + + ErrorDocument 301 "Some message + + Note the opening " quote, without a closing quote. It now + has either the following syntaxes + + ErrorDocument XXX /local/uri + ErrorDocument XXX http://valid/url + ErrorDocument XXX "Some Message" + + The recognition heuristic is: if it has a space it + is a message.

+  *) PORT: The semantics of accept/select make it very desirable to use
+     mutexes to serialize accept when multiple Listens are in use.  But
+     in the case where only a single socket is open it is sometimes
+     redundant to serialize accept().  Not all unixes do a good job with
+     potentially dozens of children blocked on accept() on the same
+     socket.  It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
+     the server will avoid serialization when listening on only one socket,
+     and use serialization when listening on multiple sockets.

+  *) Configure changes: TestLib replaced by TestCompile, which has
+     some additional capability (such as doing a sanity check of
+     the compiler and flags selected); the version of Solaris is now
+     available via the #define value of SOLARIS2; IRIX n32bit libs

+  *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
+     N is the number of <Directory> sections, and M is the number of
+     components in the filename of an object.
+
+     To achieve this optimization the following config changes were made:
+        - Wildcards (* and ?, not the regex forms) in <Directory>s,
+          <Files>s, and <Location>s now treat a slash as a special
+          character.  For example "/home/*/public_html" previously would
+          match "/home/a/andrew/public_html", now it only matches things
+          like "/home/bob/public_html".  This mimics /bin/sh behaviour.
+        - It's possible now to use [] wildcarding in <Directory>, <Files>
+          or <Location>.
+        - Regex <Directory>s are applied after all non-regex <Directory>s.

+     First the grouped parts of RewriteRule pattern matches (parenthesis!) can
+     be accessed now via backreferences $1..$9 in RewriteConds test-against
+     strings in addition to RewriteRules subst string. Second the grouped
+     parts of RewriteCond pattern matches (parenthesis!) can be accessed now
+     via backreferences %1..%9 both in following RewriteCond test-against
+     strings and RewriteRules subst string. This provides maximum flexibility
+     through the use of backreferences.
+     Additionally the rewriting engine was cleaned up by putting common

+            - if that fails, just pretend it matched the main server
+            - if so far only the main server has been matched, perform

+              *only on name-based vhosts*

+     - The undocumented syntax "allow user-agents" was removed,
+       the replacement is "allow from env=foobar" combined with mod_browser.
+     - When used with hostnames it now forces a double-reverse lookup
+       no matter what the directory settings are.  This double-reverse
+       doesn't affect any of the other routines that use the remote
+       hostname.  In particular it's still passed to CGIs and the log

+     in a language that by default does buffering (e.g. perl) this
+     shouldn't have a detrimental effect on performance.
+
+     "nph-" CGIs, which formerly provided a direct socket to the client

+     read of a new request uses a 256 byte buffer. We check the bytes written
+     so far and, if we are about to tickle the bug, we instead insert a

+
+  *) Fixed status of response when POST is received for a nonexistent URL
+     (was sending 405, now 404) and when any method is sent with a

+     before being reported.  [Dean Gaudet]
+
+  *) In the proxy, if the cache filesystem was full, garbage_coll() was
+     never called, and thus the filesystem would remain full indefinitely.
+     We now also remove incomplete cache files left if the origin server
+     didn't send a Content-Length header and either the client has aborted
+     transfer or bwrite() to client has failed. [Petr Lampa]
+
+  *) Fixed the handling of module and script-added header fields.
+     Improved the interface for sending header fields and reduced
+     the duplication of code between sending okay responses and errors.
+     We now always send both headers_out and err_headers_out, and
+     ensure that the server-reserved fields are not being overridden,
+     while not overriding those that are not reserved.  [Roy Fielding]
+
+  *) Moved transparent content negotiation fields to err_headers_out
+     to reflect above changes.  [Petr Lampa]
+
+  *) Fixed the determination of whether or not we should make the
+     connection persistent for all of the cases where some other part
+     of the server has already indicated that we should not.  Also
+     improved the ordering of the test so that chunked encoding will
+     be set whenever it is desired instead of only when KeepAlive
+     is enabled. Added persistent connection capability for most error
+     responses (those that do not indicate a bad input stream) when
+     accessed by an HTTP/1.1 client. [Roy Fielding]
+
+  *) Added missing timeouts for sending header fields, error responses,
+     and the last chunk of chunked encoding, each of which could have
+     resulted in a process being stuck in write forever.  Using soft_timeout
+     requires that the sender check for an aborted connection rather than
+     continuing after an EINTR.  Timeouts that used to be initiated before
+     send_http_header (and never killed) are now initiated only within or
+     around the routines that actually do the sending, and not allowed to
+     propagate above the caller.  [Roy Fielding]

+     with the same IP address) failing. [Dean Gaudet]
+
+  *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
+     AIX; improves the redirection stuff to enable the users to generally
+     redirect to http, https, gopher and ftp; added TIME variable for
+     RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
+     special patterns >STRING, <STRING and =STRING to RewriteCond, which
+     can be used in conjunction with %{TIME} or other variables to create

+  *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
+     Module authors may need to adjust their code for proper cleanup to take

+     until the BUFF code is actually about to read the next request.
+     This fixes a problem introduced in 1.2b5 with clients that send
+     an extra CRLF after a POST request. Also improved chunked output
+     performance by combining writes using writev() and removing as
+     many bflush() calls as possible.  NOTE: Platforms without writev()
+     must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration

+     execution for ~userdir CGI. [Jason Dour]
+
+  *) Fix initgroups() business in suexec wrapper. [Jason Dour]
+
+  *) Fix month off by one in suexec wrapper logging.
+
+Changes with Apache 1.2b3:
+
+  *) Fix error in mod_cgi which could cause resources not to be properly
+     freed, or worse. [Dean Gaudet]
+
+  *) Fix find_string() NULL pointer dereference. [Howard Fear]
+
+  *) Add set_flag_slot() at the request of Dirk and others.
+     [Dirk vanGulik]
+
+  *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
+
+  *) Add changes to improve the error message given for invalid
+     ServerName parameters. [Dirk vanGulik]
+
+  *) Add "Authoritative" directive for Auth modules that don't
+     currently have it. This gives admin control to assign authoritative
+     control to an authentication scheme and allow "fall through" for
+     those authentication modules that aren't "Authoritative" thereby
+     allowing multiple authentication mechanisms to be chained.
+     [Dirk vanGulik]
+
+  *) Remove requirement for ResourceConfig/AccessConfig if not using
+     the three config file layout. [Randy Terbush]
+
+  *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
+
+  *) Changes to suexec wrapper to fix the following problems:
+     1.  symlinked homedirs will kill ~userdirs.
+     2.  initgroups() on Linux 2.0.x clobbers gr->grid.
+     3.  CGI command lines paramters problems
+     4.  pw-pwdir for "docroot check" still the httpd user's pw record.
+    [Randy Terbush, Jason Dour]
+
+  *) Change create_argv() to accept variable arguments. This fixes
+     a problem where arguments were not getting passed to the CGI via
+     argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
+
+  *) Collapse multiple slashes in path URLs to properly apply
+     handlers defined by <Location>. [Alexei Kosut]
+
+  *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
+
+  *) Improve the accuracy of request duration timings by setting
+     r->request_time in read_request_line() instead of read_request().
+     [Dean Gaudet]
+
+  *) Reset timeout while reading via get_client_block() in mod_cgi.c
+     Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
+
+  *) Add the ability to pass different Makefile.tmpl files to Configure
+     using the -make flag. [Rob Hartill]
+
+  *) Fix coredump triggered when sending a SIGHUP to the server caused
+     by an assertion failure, in turn caused by an uninitialised field in a
+     listen_rec.
+     [Ben Laurie]
+
+  *) Add FILEPATH_INFO variable to CGI environment, which is equal to
+     PATH_INFO from previous versions of Apache (in certain situations,
+     Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
+     [later removed in 1.2b11]
+
+  *) Add rwrite() function to API to allow for sending strings of
+     arbitrary length. [Doug MacEachern]
+
+  *) Remove rlim_t typedef for NetBSD. Do older versions need this?
+
+  *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
+     NeXT. [Jim Jagielski]
+
+  *) Removed recent modification to promote the status code on internal
+     redirects, since the correct fix was to change the default log format
+     in mod_log_config so that it outputs the original status. [Rob Hartill]
+
+Changes with Apache 1.2b2:
+
+  *) Update set_signals() to use sigaction() for setting handlers.
+     This appears to fix a re-entrant problem in the seg_fault()
+     bus_error() handlers. [Randy Terbush]
+
+  *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
+
+  *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
+
+  *) proxy_http.c bugfixes:  [Chuck Murcko]
+        1) fixes possible NULL pointer reference w/NoCache
+        2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
+           host would cache nothing if it was in the local domain,
+           and the local domain was in the NoCache list)
+        3) Adds Host: header when not available
+        4) Some code cleanup and clarification
+
+  *) mod_include.c bugfixes:
+        1) Fixed an ommission that caused include variables to not
+           be parsed in config errmsg directives [Howard Fear]
+        2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
+        3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
+        4) Allow backslash-escaping to all quoted text
+           [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
+        5) Pass variable to command line if not set in XSSI's env
+           [Howard Fear]
+
+  *) Fix infinite loop when processing Content-language lines in
+     type-map files. [Alexei Kosut]
+
+  *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
+
+  *) Fixed problem in set_[user|group] that prevented CGI execution
+     for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
+
+  *) Added PORTING information file.  [Jim Jagielski]
+
+  *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
+
+  *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
+
+  *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
+     USE_FCNTL_SERIALIZED_ACCEPT was intended.
+
+  *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
+     which caused problems of systems where socket s_addr is >32bits.
+
+  *) Added comment to explain (r->chunked = 1) side-effect in
+     http_protocol.c [Roy Fielding]
+
+  *) Replaced use of index() in mod_expires.c with more appropriate
+     and portable isdigit() test.  [Ben Laurie]
+
+  *) Updated Configure for ...
+        OS/2          (DEF_WANTHSREGEX=yes, other code changes)
+        *-dg-dgux*    (bad pattern match)
+        QNX           (DEF_WANTHSREGEX=yes)
+        *-sunos4*     (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
+        *-ultrix      (new)
+        *-unixware211 (new)
+     and added some user diagnostic info.  [Ben Laurie]
+
+  *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
+     for better portability. [Jim Jagielski]
+
+  *) Updated helpers/GuessOS for ...
+        SCO 5            (recognize minor releases)
+        SCO UnixWare     (braindamaged uname, whatever-whatever-unixware2)
+        SCO UnixWare 2.1.1      (requires a separate set of #defines in conf.h)
+        IRIX64           (-sgi-irix64)
+        ULTRIX           (-unknown-ultrix)
+        SINIX            (-whatever-sysv4)
+        NCR Unix         (-ncr-sysv4)
+     and fixed something in helpers/PrintPath  [Ben Laurie]
+
+Changes with Apache 1.2b1
+
+  *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>

+     leak. [Nathan Neulinger]
+
+  *) MultiViews now works correctly with AddHandler [Alexei Kosut]
+
+  *) Problems with mod_auth_msql fixed [Dirk vanGulik]
+
+  *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
+
+Changes with Apache 1.1.0
+
+  *) Bring NeXT support up to date. [Takaaki Matsumoto]
+
+  *) Bring QNX support up to date. [Ben Laurie]
+
+  *) Make virtual hosts default to main server keepalive parameters.
+     [Alexei Kosut, Ben Laurie]
+
+  *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
+
+  *) Fix missing address family for connect, also remove unreachable statement
+     in mod_proxy. [Ben Laurie]
+
+  *) mod_env now turned on by default in Configuration.tmpl.
+
+  *) Bugs which were fixed:
+        a) yet more mod_proxy bugs [Ben Laurie]
+        b) CGI works again with inetd [Alexei Kosut]
+        c) Leading colons were stripped from passwords [osm@interguide.com]
+        d) Another fix to multi-method Limit problem [jk@tools.de]
+
+Changes with Apache 1.1b4
+
+  *) r->bytes_sent variable restored. [Robert Thau]
+
+  *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
+
+  *) More possibly unsecure programs removed from the support directory.
+
+  *) More mod_auth_msql authentication improvements.
+
+  *) VirtualHosts based on Host: headers no longer conflict with the
+     Listen directive.
+
+  *) OS/2 compatibility enhancements. [Gary Smiley]
+
+  *) POST now allowed to directory index CGI scripts.
+
+  *) Actions now work with files of the default type.
+
+  *) Bugs which were fixed:
+        a) more mod_proxy bugs
+        b) early termination of inetd requests
+        c) compile warnings on several systems
+        d) problems when scripts stop reading output early
+
+Changes with Apache 1.1b3
+
+  *) Much of cgi-bin and all of cgi-src has been removed, due to
+     various security holes found and that we could no longer support
+     them.
+
+  *) The "Set-Cookie" header is now special-cased to not merge multiple
+     instances, since certain popular browsers can not handle multiple
+     Set-Cookie instructions in a single header. [Paul Sutton]
+
+  *) rprintf() added to buffer code, occurrences of sprintf removed.
+     [Ben Laurie]
+
+  *) CONNECT method for proxy module, which means tunneling SSL should work.
+     (No crypto needed)  Also a NoCache config directive.
+
+  *) Several API additions: pstrndup(), table_unset() and get_token()
+     functions now available to modules.
+
+  *) mod_imap fixups, in particular Location: headers are now complete
+     URL's.
+
+  *) New "info" module which reports on installed module set through a
+     special URL, a la mod_status.
+
+  *) "ServerPath" directive added - allows for graceful transition
+     for Host:-header-based virtual hosts.
+
+  *) Anonymous authentication module improvements.
+
+  *) MSQL authentication module improvements.
+
+  *) Status module design improved - output now table-based. [Ben Laurie]

+  *) htdigest utility included for use with digest authentication
+     module.
+

+     less priority than those without wildcards at the same quality
+     value. [Alexei Kosut]

+  *) Bugs which were fixed:
+        a) numerous mod_proxy bugs
+        b) CGI early-termination bug [Ben Laurie]
+        c) Keepalives not working with virtual hosts
+        d) RefererIgnore problems
+        e) closing fd's twice in mod_include (causing core dumps on

+        a) core dumps in mod_digest
+        b) truncated hostnames/ip address in the logs
+        c) relative URL's in mod_imap map files
+
+Changes with Apache 1.1b1
+
+  *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
+
+Changes with Apache 1.0.3
+
+  *) Internal redirects which occur in mod_dir.c now preserve the
+     query portion of a request (the bit after the question mark).

+
+  *) Escape active characters '<', '>' and '&' in html output in
+     directory listings, error messages and redirection links.
+     [David Robinson]
+
+  *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
+
+  *) Fix for POSIX compliance in waiting for processes in alloc.c.
+     [Nick Williams]
+
+  *) setsockopt no longer takes a const declared argument [Martijn Koster]
+
+  *) Reset timeout timer after each successful fwrite() to the network.
+     This patch adds a reset_timeout() procedure that is called by
+     send_fd() to reset the timeout ever time data is written to the net.
+     [Nathan Schrenk]
+
+  *) timeout() signal handler now checks for SIGPIPE and reports
+     lost connections in a more user friendly way. [Rob Hartill]
+
+  *) Location of the "scoreboard" file which used to live in /tmp is
+     now configurable (for OSes that can't use mmap) via ScoreBoardFile
+     which works similar to PidFile (in httpd.conf) [Rob Hartill]
+
+  *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
+
+  *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
+     which caused a SEGV with cookies enabled
+
+  *) Output warning when MinSpareServers is set to <= 0 and change it to 1
+     [Rob Hartill]
+
+  *) Log the UNIX textual error returned by some system calls, in
+     particular errors from accept() [David Robinson]
+
+  *) Add strerror function to util.c for SunOS4 [Randy Terbush]
+
+Changes with Apache 1.0.2
+
+  *) patch to get Apache compiled on UnixWare 2.x, recommended as
+     a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
+
+  *) Fix get_basic_auth_pw() to set the auth_type of the request.
+     [David Robinson]
+
+  *) past changes to http_config.c to only use the
+     setrlimit function on systems defining RLIMIT_NOFILE
+     broke the feature on SUNOS4. Now defines HAVE_RESOURCE
+     for SUNOS and prototypes the needed functions.
+
+  *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
+     [David Robinson]
+
+  *) Fix use of pointer to scratch memory. [Cliff Skolnick]
+
+  *) Merge multiple headers from CGI scripts instead of taking last
+     one. [David Robinson]
+
+  *) Add support for SCO 5. [Ben Laurie]
+
+Changes with Apache 1.0.1
+
+  *) Silence mod_log_referer and mod_log_agent if not configured
+     [Randy Terbush]
+
+  *) Recursive includes can occur if the client supplies PATH_INFO data
+     and the server provider uses relative links; as file.html
+     relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
+
+  *) The replacement for initgroups() did not call {set,end}grent(). This
+     had two implications: if anything else used getgrent(), then
+     initgroups() would fail, and it was consuming a file descriptor.
+     [Ben Laurie]
+
+  *) On heavily loaded servers it was possible for the scoreboard to get
+     out of sync with reality, as a result of a race condition.
+     The observed symptoms are far more Apaches running than should
+     be, and heavy system loads, generally followed by catastrophic
+     system failure. [Ben Laurie]
+
+  *) Fix typo in license. [David Robinson]
+
+Changes with Apache 1.0.0                                        23 Nov 1995

+
+  *) New man page for 'httpd' added to support directory [David Robinson]
+
+  *) .htgroup files can have more than one line giving members for a
+     given group (each must have the group name in front), for NCSA
+     back-compatibility [Robert Thau]
+
+  *) Mutual exclusion around accept() is on by default for SVR4 systems
+     generally, since they generally can't handle multiple processes in
+     accept() on the same socket.  This should cure flaky behavior on
+     a lot of those systems.  [David Robinson]
+
+  *) AddType, AddEncoding, and AddLanguage directives take multiple
+     extensions on a single command line [David Robinson]
+
+  *) UserDir can be disabled for a given virtual host by saying
+     "UserDir disabled" in the <VirtualHost> section --- it was a bug
+     that this didn't work.  [David Robinson]
+
+  *) Compiles on QNX [Ben Laurie]
+
+  *) Corrected parsing of ctime time format [David Robinson]
+
+  *) httpd does a perror() before exiting if it can't log its pid
+     to the PidFile, to make diagnosing the error a bit easier.
+     [David Robinson]
+
+  *) <!--#include file="..."--> can no longer include files in the
+     parent directory, for NCSA back-compatibility.  [David Robinson]
+
+  *) '~' is *not* escaped in URIs generated for directory listings
+     [Roy Fielding]
+
+  *) Eliminated compiler warning in the imagemap module [Randy Terbush]
+
+  *) Fixed bug involving handling URIs with escaped %-characters
+     in redirects [David Robinson]
+
+Changes with Apache 0.8.15                                       14 Oct 1995
+
+  *) Switched to new, simpler license
+
+  *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
+
+  *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
+
+  *) Reject paths containing %-escaped '%' or null characters [David Robinson]
+
+  *) Correctly handles internal redirects to files with names containing '%'
+     [David Robinson]
+
+  *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
+
+  *) Use geteuid() rather than getuid() to see if we have root privilege,
+     so that server correctly resets privilege if run setuid root.  [Andrew
+     Wilson]
+
+  *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
+     [Randy Terbush]
+
+  *) Fix relative URLs in imagemap files [Randy Terbush]
+
+  *) Somewhat better fix for the old "Alias /foo/ /bar/" business
+     [David Robinson]
+
+  *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
+     entries all name the same one. [David Robinson]
+
+  *) Fix directory listings with filenames containing unusual characters
+     [David Robinson]
+
+  *) Better URI-escaping for generated URIs in directories with filenames
+     containing unusual characters [Ben Laurie]
+
+  *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
+
+  *) Unblock alarms on error return from spawn_child() [David Robinson]
+
+  *) Sample Config files have extra note for SCO users [Ben Laurie]
+
+  *) Configuration has note for HP-UX users [Rob Hartill]
+
+  *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
+
+  *) Nuked bogus #define in httpd.h [David Robinson]
+
+  *) Better test for whether a system has setrlimit() [David Robinson]
+
+  *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
+
+  *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
+     [Ben Laurie]
+
+Changes with Apache 0.8.14                                       19 Sep 1995
+
+  *) Compiles on SCO ODT 3.0 [Ben Laurie]
+
+  *) AddDescription works (better) [Ben Laurie]
+
+  *) Leaves an intelligible error diagnostic when it can't set group
+     privileges on standalone startup [Andrew Wilson]
+
+  *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
+     that machine, which claims to be BSD but does not support RLIMIT.
+     [Randy Terbush]
+
+  *) gcc -Wall no longer complains about an unused variable when util.c
+     is compiled with -DMINIMAL_DNS [Andrew Wilson]
+
+  *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
+
+Changes with Apache 0.8.13                                       07 Sep 1995
+
+  *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
+
+  *) Have built-in imagemap code recognize & honor Point directive [James
+     Cloos]
+
+  *) Generate cleaner directory listings in directories with a mix of
+     long and short filenames [Rob Hartill]
+
+  *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
+
+  *) Properly default ServerName for virtual servers [Robert Thau]
+
+  *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
+     Paul Richards and a cast of thousands...]
+
+  *) On self-identified BSD systems (we don't try to guess any more),
+     allocate a few extra file descriptors per virtual host with setrlimit,
+     if we can, to avoid running out. [Randy Terbush]
+
+  *) Write 22-character lock file name into buffer with enough space
+     on startup [Konstantin Olchanski]
+
+  *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
+     Pinkerton]
+
+  *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]

+  *) Suppress -Wall warning by initializing variable in negotiation code
+     [Tobias Weingartner]

+Changes with Apache 0.8.12                                       31 Aug 1995
+
+  *) Doesn't pause three seconds after including a CGI script which is
+     too slow to die off (this is done by not even trying to kill off
+     subprocesses, including the SIGTERM/pause/SIGKILL routine, until
+     after the entire document has been processed).  [Robert Thau]
+
+  *) Doesn't do SSI if Options Includes is off.  (Ooops).  [David Robinson]
+
+  *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
+
+  *) Allows .htaccess files to override <Directory> sections naming the
+     same directory [David Robinson]
+
+  *) Removed an efficiency hack in sub_req_lookup_uri which was
+     causing certain extremely marginal cases (e.g., ScriptAlias of a
+     *particular* index.html file) to fail.  [David Robinson]
+
+  *) Doesn't log an error when the requested URI requires
+     authentication, but no auth header line was supplied by the
+     client; this is a normal condition (the client doesn't no auth is
+     needed here yet).  [Robert Thau]
+
+  *) Behaves more sanely when the name server loses its mind [Sean Welch]
+
+  *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
+
+  *) RFC931 code no longer passes out name of prior clients on current
+     requests if the current request came from a server that doesn't
+     do RFC931.  [David Robinson]
+
+  *) Configuration script accepts "Module" lines with trailing whitespace.
+     [Robert Thau]
+
+  *) Cleaned up compiler warning from mod_access.c [Robert Thau]
+
+  *) Cleaned up comments in mod_cgi.c [Robert Thau]
+
+Changes with Apache 0.8.11                                       24 Aug 1995
+
+  *) Wildcard <Directory> specifications work.  [Robert Thau]
+
+  *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
+
+  *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
+     the file being requested itself, in addition to the directories leading
+     up to it. [Robert Thau]
+
+  *) Logs access failures due to symlink checks or invalid client address
+     in the error log [Roy Fielding, Robert Thau]
+
+  *) Symlink checks deal correctly with systems where lstat of
+     "/path/to/some/link/" follows the link.  [Thau, Fielding]
+
+  *) Doesn't reset DirectoryIndex to 'index.html' when
+     other directory options are set in a .htaccess file.  [Robert Thau]
+
+  *) Clarified init code and nuked bogus warning in mod_access.c
+     [Florent Guillaume]
+
+  *) Corrected several directives in sample srm.conf
+     --- includes corrections to directory indexing icon-related directives
+     (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
+     icons for encodings right, and turning on AddEncoding by default).
+     [Roy Fielding]
+
+  *) Corrected descriptions of args to AddIcon and AddAlt in command table
+     [James Cloos]
+
+  *) INSTALL & README mention "contributed modules" directory [Brian
+     Behlendorf]
+
+  *) Fixed English in the license language...  "for for" --> "for".
+     [Roy Fielding]
+
+  *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
+     mod_alias.c, merging it almost completely with handling of Alias, and
+     adding a 'notes' field to the request_rec which allows the CGI module
+     to discover whether the Alias module has put this request through
+     ScriptAlias (which it needs to know for back-compatibility, as the old
+     NCSA code did not check Options ExecCGI in ScriptAlias directories).

+
+  *) AllowOverride applies to the named directory, and not just
+     subdirectories.  [David Robinson]
+
+  *) Do locking for accept() exclusion (on systems that need it)
+     using a special file created for the purpose in /usr/tmp, and
+     not the error log; using the error log causes real problems
+     if it's NFS-mounted; this is known to be the cause of a whole
+     lot of "server hang" problems with Solaris.  [David Robinson;
+     thanks to Merten Schumann for help diagnosing the problem].
+
+Changes with Apache 0.8.9                                        12 Aug 1995
+
+  *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
+
+  *) Nested includes see environment variables of the including document,
+     for NCSA bug-compatibility (some sites have standard footer includes
+     which try to print out the last-modified date).  [Eric Hagberg/Robert
+     Thau]
+
+  *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
+     URI as a CGI script, even if it would have been treated as something
+     else if requested directly, for NCSA back-compatibility.  (Note that
+     this means that people who know the name of the script can see the
+     code just by asking for it).  [Robert Thau]
+
+  *) New version of dbmmanage script included in support directory as
+     dbmmanage.new.
+
+  *) Check if scoreboard file couldn't be opened, and say so, rather
+     then going insane [David Robinson]
+
+  *) POST to CGI works on A/UX [Jim Jagielski]
+
+  *) AddIcon and AddAlt commands work properly [Rob Hartill]
+
+  *) NCSA server push works properly --- the Arena bug compatibility
+     workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
+     if you still want the workaround).  [Rob Hartill]
+
+  *) If client didn't submit any Accept-encodings, ignore encodings in
+     content negotiation.  (NB this will all have to be reworked anyway
+     for the new HTTP draft).  [Florent Guillaume]
+
+  *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
+
+  *) Really honor CacheNegotiatedDocs [Florent Guillaume]
+
+  *) Give Redirect priority over Alias, for NCSA bug compatibility
+     [David Robinson]
+
+  *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
+     paralleling earlier bug fix for CGI [David Robinson]
+
+  *) If DBM auth is improperly configured, report a server error and don't
+     dump core.
+
+  *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
+     it seems to work well enough without it (even in a 10 hits/sec
+     workout), and the overhead for the locking under A/UX is
+     alarmingly high (though it is very low on other systems).
+     [Eric Hagberg, Jim Jagielski]
+

+
+  *) Further de-Berklize mod_cookies.c; change the bogus #include.  [Brian

+
+  *) Compiles clean on NEXT [Rob Hartill]

+
+Changes with Apache 0.8.8                                        08 Aug 1995
+
+  *) SunOS library prototypes now never included unless explicitly
+     requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
+     people using GNU libc on SunOS are screwed by prototypes for the
+     standard library.
+
+     (Those who wish to compile clean with gcc -Wall on a standard
+     SunOS setup need the prototypes, and may obtain them using
+     -DSUNOS_LIB_PROTOTYPES.  Those wishing to use -Wall on a system
+     with nonstandard libraries are presumably competent to make their
+     own arrangements).
+
+  *) Strips trailing '/' characters off both args to the Alias command,
+     to make 'Alias /foo/ /bar/' work.

+

+
+  *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
+     (If you actually wanted a conditional GET which bypassed the cache, you
+     couldn't get it). [Reported by Roy Fielding]
+
+  *) Properly terminate headers on '304 Not Modified' replies to conditional
+     GETs --- no browser we can find cares much, but the CERN proxy chokes.
+     [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
+
+  *) httpd -v doesn't call itself "Shambhala".  [Reported by Chuck Murcko]
+
+  *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
+     not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
+     and older versions don't set the __SUNPRO_C preprocessor variable).  On
+     all other systems, these are never used anyway.  [Reported by Mark Cox].
+
+  *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
+
+Changes with Apache 0.8.5                                        01 Aug 1995
+
+  *) Added last-minute configurable log experiment, as optional module
+
+  *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
+     properly.  (One-line fix to http_protocol.c).
+
+  *) Work around bogus behavior when reloading from Netscape.
+     It's Netscape's bug --- for some reason they expect a request with
+     If-modified-since: to not function as a conditional GET if it also
+     comes with Pragma: no-cache, which is way out of line with the HTTP
+     spec (according to Roy Fielding, the redactor).
+
+  *) Added parameter to set maximum number of server processes.
+
+  *) Added patches to make it work on A/UX.  A/UX is *weird*.  [Eric Hagberg,
+     Jim Jagielski]
+
+  *) IdentityCheck bugfix [Chuck Murcko].
+
+  *) Corrected cgi-src/Makefile entry for new imagemap script.  [Alexei Kosut]
+
+  *) More sample config file corrections; add extension to AddType for
+     *.asis, move AddType generic description to its proper place, and
+     fix miscellaneous typos. [ Alexei Kosut ]
+
+  *) Deleted the *other* reference to the regents from the Berkeley
+     legal disclaimer (everyplace).
+
+  *) Nuked Shambhala name from src/README; had already cleaned it out
+     of everywhere else.
+
+Changes with Apache 0.8.4
+
+  *) Changes to server-pool management parms --- renamed current
+     StartServers to MinSpareServers, created separate StartServers
+     parameter which means what it says, and renamed MaxServers to
+     MaxSpareServers (though the old name still works, for NCSA 1.4
+     back-compatibility).  The old names were generally regarded as
+     too confusing.  Also altered "docs" in sample config files.
+
+  *) More improvements to default config files ---
+     sample directives (commented out) for XBitHack, BindAddress,
+     CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
+     defaults, AddTypes for send-as-is and imagemap magic types, and
+     improvements to samples for DirectoryIndex [Alexei Kosut]
+
+  *) Yet more improvements to default config files --- changes to
+     Alexei's sample AddLanguage directives, and sample LanguagePriority
+     [ Florent Guillaume ]
+
+  *) Set config file locations properly if not set in httpd.conf
+     [ David Robinson ]
+
+  *) Don't escape URIs in internal redirects multiple times; don't
+     do that when translating PATH_INFO to PATH_TRANSLATED either.
+     [ David Robinson ]
+
+  *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
+
+Changes with Apache 0.8.3
+
+  *) Edited distribution README to *briefly* summarize installation
+     procedures, and give a pointer to the INSTALL file in the src/
+     directory.
+
+  *) Upgraded imagemap script in cgi-bin to 1.8 version from more
+     recent NCSA distributions.
+
+  *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
+     exist for the same directory, use both and don't segfault.  [Reported
+     by David Robinson]
+
+  *) Proper makefile dependencies [David Robinson]
+
+  *) Note (re)starts in error log --- reported by Rob Hartill.
+
+  *) Only call no2slash() after get_path_info() has been done, to
+     preserve multiple slashes in the PATH_INFO [NCSA compatibility,
+     reported by Andrew Wilson, though this one is probably a real bug]
+
+  *) Fixed mod_imap.c --- relative paths with base_uri referer don't
+     dump core when Referer is not supplied. [Randy Terbush]
+
+  *) Lightly edited sample config files to refer people to our documentation
+     instead of NCSA's, and to list Rob McCool as *original* author (also
+     deleted his old, and no doubt non-functional email address).  Would be
+     nice to have examples of new features...
+
+Changes with Apache 0.8.2                                        19 Jul 1995
+
+  *) Added AddLanuage code [Florent Guillaume]
+
+  *) Don't say "access forbidden" when a CGI script is not found.  [Mark Cox]
+
+  *) All sorts of problems when MultiViews finds a directory.  It would
+     be nice if mod_dir.c was robust enough to handle that, but for now,
+     just punt.  [reported by Brian Behlendorf]
+
+  *) Wait for all children on restart, to make sure that the old socket
+     is gone and we can reopen it.  [reported by Randy Terbush]
+
+  *) Imagemap module is enabled in default Configuration
+
+  *) RefererLog and UserAgentLog modules properly default the logfile
+     [Randy Terbush]
+
+  *) Mark Cox's mod_cookies added to the distribution as an optional
+     module (commented out in the default Configuration, and noted as
+     an experiment, along with mod_dld). [Mark Cox]
+
+  *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
+
+  *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
+
+  *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
+
+  *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
+     license]
+
+Changes with Apache 0.8.1
+
+  *) New imagemap module [Randy Terbush]
+
+  *) Replacement referer log module with NCSA-compatible RefererIgnore
+     [Matthew Gray again]
+
+  *) Don't mung directory listings with very long filenames.
+     [Florent Guillaume]
+
+Changes with Apache 0.8.0 (nee Shambhala 0.6.2)                  16 Jul 1995
+
+  *) New config script.  See INSTALL for info.  [Robert Thau]
+
+  *) Scoreboard mechanism for regulating the number of extant server
+     processes.  MaxServers and StartServers defaults are the same as
+     for NCSA, but the meanings are slightly different.  (Actually,
+     I should probably lower the MaxServers default to 10).
+
+     Before asking for a new connection, each server process checks
+     the number of other servers which are also waiting for a
+     connection.  If there are more than MaxServers, it quietly dies
+     off.  Conversely, every second, the root, or caretaker, process
+     looks to see how many servers are waiting for a new connection;
+     if there are fewer than StartServers, it starts a new one.  This
+     does not depend on the number of server processes already extant.
+     The accounting is arranged through a "scoreboard" file, named
+     /tmp/htstatus.*, on which each process has an independent file
+     descriptor (they need to seek without interference).
+
+     The end effect is that MaxServers is the maximum number of
+     servers on an *inactive* server machine, but more will be forked
+     off to handle unusually heavy loads (or unusually slow clients);
+     these will die off when they are no longer needed --- without
+     reverting to the overhead of full forking operation.  There is a
+     hard maximum of 150 server processes compiled in, largely to
+     avoid forking out of control and dragging the machine down.
+     (This is arguably too high).
+
+     In my server endurance tests, this mechanism did not appear to
+     impose any significant overhead, even after I forced it to put the
+     scoreboard file on a normal filesystem (which might have more
+     overhead than tmpfs).  [Robert Thau]
+
+  *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
+     [Cliff Skolnick]
+
+  *) Read .htaccess files even in directory with <Directory> section.
+     (Former incompatibility noted on mailing list, now fixed). [Robert
+     Thau]
+
+  *) "HEAD /" gives the client a "Bad Request" error message, rather
+     than trying to send no body *and* no headers.  [Cliff Skolnick].
+
+  *) Don't produce double error reports for some very obscure cases
+     mainly involving auth configuration (the "all modules decline to
+     handle" case which is a sure sign of a server bug in most cases,
+     but also happens when authentication is badly misconfigured).
+     [Robert Thau]
+
+  *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
+     it's *for*, and this sort of thing really shouldn't be cluttering
+     up the Makefile). [Robert Thau]
+
+  *) Incidental code cleanups in http_main.c --- stop dragging
+     sa_client around; just declare it where used.  [Robert Thau]
+
+  *) Another acc-related fix.  (It doesn't like const char
+     in some places...). [Mark Cox]
+
+Changes with Shambhala 0.6.1                                     13 Jul 1995
+
+  *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
+     Also, fixed auth typo in http_protocol.c unmasked by this fix.
+
+  *) Compiles clean with acc on SunOS [Paul Sutton]
+
+  *) Reordered modules in modules.c so that Redirect takes priority
+     over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
+     believe it or not, he has an actual site with a ScriptAlias and
+     a Redirect declared for the *exact same directory*.  Even *my*
+     compatibility fetish wouldn't motivate me to fix this if the fix
+     required any effort, but it doesn't, so what the hey.
+
+  *) Fixed to properly default several server_rec fields for virtual
+     servers from the corresponding fields in the main server_rec.
+     [Cliff Skolnick --- 'port' was a particular irritant].
+
+  *) No longer kills off nph- child processes before they are
+     finished sending output. [Matthew Gray]
+
+Changes with Shambhala 0.6.0                                     10 Jul 1995
+
+  *) Two styles of timeout --- hard and soft.  soft_timeout()s just put
+     the connection to the client in an "aborted" state, but otherwise
+     allow whatever handlers are running to clean up.  hard_timeout()s
+     abort the request in progress completely; anything not tied to some
+     resource pool cleanup will leak.  They're still around because I
+     haven't yet come up with a more elegant way of handling
+     timeouts when talking to something that isn't the client.  The
+     default_handler and the dir_handler now use soft timeouts, largely
+     so I can test the feature.  [Robert Thau]
+
+  *) TransferLog "| my_postprocessor ..." seems to be there.  Note that
+     the case of log handlers dying prematurely is probably handled VERY
+     gracelessly at this point, and if the logger stops reading input,
+     the server will hang.  (It is known to correctly restart the
+     logging process on server restart; this is (should be!) going through
+     the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
+     script).  [Robert Thau]
+
+  *) asis files supported (new module).  [Robert Thau]
+
+  *) IdentityCheck code is compiled in, but has not been tested.  (I
+     don't know anyone who runs identd). [Robert Thau]
+
+  *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
+     came in with the request, for NCSA bug-compatibility. [Robert Thau]
+
+  *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
+
+  *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
+     as timeouts are not in scope. [Robert Thau]
+
+  *) quoted-string args in config files now handled correctly (doesn't drop
+     the last character). [Robert Thau; reported by Randy Terbush]
+
+  *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
+     How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
+
+  *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
+     default default type); the former default default behavior when all
+     type-checkers defaulted had been a core dump.  [Paul Sutton]
+
+  *) Copy filenames out of the struct dirent when indexing
+     directories.  (On Linux, readdir() returns a pointer to the same
+     memory area every time).  Fix is in mod_dir.c.  [Paul Sutton]
+
+Changes with Shambhala 0.5.3 [not released]
+
+  *) Default response handler notes "file not found" in the error log,
+     if the file was not found.  [Cliff Skolnick].
+
+  *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
+     code no longer sets up bogus PATH_INFO which fakes out the directory
+     handler). [Cliff Skolnick]
+
+Changes with Shambhala 0.5.2                                     06 Jul 1995
+
+  *) Changes to http_main.c --- root server no longer plays silly
+     games with SIGCHLD, and so now detects and replaces dying
+     children.  Child processes just die on SIGTERM, without taking
+     the whole process group with them.  Potential problem --- if any
+     child process refuses to die, we hang in restart.
+     MaxRequestsPerChild may still not work, but it certainly works
+     better than it did before this!  [Robert Thau]
+
+  *) mod_dir.c bug fixes: ReadmeName and HeaderName
+     work (or work better, at least); over-long description lines
+     properly terminated. [Mark Cox]
+
+  *) http_request.c now calls unescape_url() more places where it
+     should [Paul Sutton].
+
+  *) More directory handling bugs (reported by Cox)
+     Parent Directory link is now set correctly. [Robert Thau]
+
+Changes with Shambhala 0.5.1                                     04 Jul 1995
+
+  *) Generalized cleanup interface in alloc.c --- any function can be
+     registered with alloc.c as a cleanup for a resource pool;
+     tracking of files and file descriptors has been reimplemented in
+     terms of this interface, so I can give it some sort of a test.
+     [Robert Thau]
+
+  *) More changes in alloc.c --- new cleanup_for_exec() function,
+     which tracks down and closes all file descriptors which have been
+     registered with the alloc.c machinery before the server exec()s a
+     child process for CGI or <!--#exec-->.  CGI children now get
+     started with exactly three file descriptors open.  Hopefully,
+     this cures the problem Rob H. was having with overly persistent
+     CGI connections. [Robert Thau]
+
+  *) Mutual exclusion around the accept() in child_main() --- this is
+     required on at least SGI, Solaris and Linux, and is #ifdef'ed in
+     by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
+     This uses fcntl(F_SETLK,...) on the error log descriptor because
+     flock() on that descriptor won't work on systems which have BSD
+     flock() semantics, including (I think) Linux 1.3 and Solaris.
+
+     This does work on SunOS (when the server is idle, only one
+     process in the pool is waiting on accept()); it *ought* to work
+     on the other systems. [Robert Thau]
+
+  *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
+
+  *) sizeof(*sa_client) bugfix from [Rob Hartill]
+
+  *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
+
+  *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
+     be unnecessary if I go to the revised timeout-handling scheme).
+     [Robert Thau]
+
+  *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
+     string) even if none came in with the request.  [Robert Thau]
+
+  *) CHANGES file added to distribution ;-).
+
+Changes with Shambhala 0.4.5
+
+  *) mod_dld --- early dynamic loading support [rst]
+  *) Add wildcard content handlers for XBITHACK; default_hander now
+     invoked with that mechanism (as a handler hanging off mod_core) [rst]
+  *) XBITHACK supported as a wildcard content-handler, and 
+     configurable at run-time (not just at compile time, as in the

+
+  *) First-cut virtual host implementation; some refit in the config
+     reading code, and log management, was necessary to support this [rst]
+  *) Sub-pool machinery, originally added to avoid excessive storage
+     allocation on listings of large directories (which turned out to
+     be the problem that the 0.3 storage accounting was added to
+     find).  Subrequests and mod_dir changed to use subpools.  [rst]

+   Major rewrite of the pre-existing "patchy server" codebase, by
+   Robert Thau (rst).  Significant portions of the server code, such
+   as configuration-file handling and HTTP authentication support,
+   were ripped out and rewritten from scratch.  Code that was not
+   completely rewritten was significantly altered.
+
+   Major changes with this release include:
+
+   *) Introduction of the module API; in request handling, the central 
+      machinery just dispatches to various modules, which actually do
+      most of the work.  Configuration handling is similar --- modules
+      declare their own commands, and the central machinery just
+      dispatches to them.  
+
+      API features from shambhala/0.1 were substantially unchanged in
+      Apache 1.0 and 1.1.  (1.0 API features not yet present in this
+      release, such as wildcard handlers and subpools, were added in
+      subsequent Shambhala releases, and were also generally rst's
+      work). 
+
+   *) This release included the following modules:
+
+      mod_access      (access control --- allow and deny directives),
+      mod_alias       (Alias and Redirect commands),
+      mod_auth        (straight HTTP authentication, based on flat-files)
+      mod_auth_dbm    (same, with dbm files)
+      mod_cgi         (CGI scripts and, in this release, ScriptAlias)
+      mod_common_log  (CLF access logs; later renamed mod_log_common)
+      mod_dir         (directory indexing)
+      mod_include     (server-side includes)
+      mod_mime        (AddType directives)
+      mod_negotiation (content negotiation)
+      mod_userdir     (support for users' public_html directories)
+
+      It also included a mod_ai_backcompat, which was a private hack
+      for back-compatibility with rst's own AI-lab servers.
+
+      All of these modules were substantially complete, and functional 
+      or nearly so (a few, which implemented features not in use at
+      Thau's site, required patches of a few lines).
+
+   *) sub-request machinery, to allow modules to determine how other
+      modules would assign MIME types to a given file, or optionally
+      serve its content (this is heavily used by mod_dir, mod_include
+      and mod_negotiation).
+
+   *) Resource pool system for keeping track of memory allocated and
+      files opened in service of a particular request.  Much of the
+      code in the modules (when they weren't rewrites) was adjusted to 
+      replace a pervasive convention of using fixed-size buffers on
+      the stack with an equally pervasive convention of using memory
+      allocated with palloc().
+
+   *) Reorganization of data structures associated with a given
+      request to eliminate use of global variables and the troublesome 
+      unmunge_name function (used in NCSA and early Apache releases to 
+      attempt to determine the URI which mapped to a given filename
+      --- a difficult proposition, given that it is easy to produce
+      setups in which multiple URIs map to the same file).
+
+   *) Source files renamed and rearranged
+
+   *) Very simple pre-forking behavior --- parent process forked off a 
+      fixed number of children, and then just waited for SIGHUP.
+
+   *) Other more minor changes too numerous to list.
+
+   This release included modified versions of a lot of code from the
+   Apache 0.6.4 public release, plus an early pre-forking patch
+   codeveloped by Robert Thau and Rob Hartill.
+
+Changes with Apache 0.7.3                                        20 Jun 1995
+
+   *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
+      were incorporated by Rob Hartill on the main branch while Robert Thau
+      worked on the Shambhala rewrite above.  Most were merged into the
+      Shambala architecture after Apache 0.8.0.
+
+Changes with Apache 0.6.4                                        13 May 1995
+
+   *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
+      and others.
+
+Changes with Apache 0.5.1                                        10 Apr 1995
+
+Changes with Apache 0.4                                          02 Apr 1995
+
+  *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
+     and Rob Hartill.
+
+Changes with Apache 0.3                                          24 Mar 1995
+
+  *) Patches by Robert Thau, David Robinson, Rob Hartill, and
+     Carlos Varela.
+
+Changes with Apache 0.2                                          18 Mar 1995
+
+  *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
+     Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
+     Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
