Describe the proxy_ftp changes:
FTP directory listings are now always retrieved in ASCII mode.
The FTP proxy properly escapes URI's and HTML in the generated
listing, and escapes the path components when talking to the FTP
server. It is now possible to browse the root directory by using
a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
Also, the last path component may contain wildcard characters
'*' and '?', and if they do, a directory listing is created instead
of a file retrieval. Example: ftp://user@host/httpd/server/*.c

For the ftp commands CWD and RETR, do escaping for the path elements,
because FTP servers do globbing, which we do not want for filenames
from the directory listing.

Added logic to the worker MPM to skip the poll before accept
if there's only one listener socket (based on the implementation
in the prefork MPM). This also enables us to do single-listener
unserialized accept
Simplify the exit paths of ap_rgetline by creating a second brigade for
use when we do AP_MODE_SPECULATIVE. This allows us to delete the
brigades earlier.
(In practice, it really doesn't matter if we delete the brigade or not
since it will be destroyed when it's pool is destroyed, but we'll try
to be nice.)

This patch restores most of Ryan's patch (11/12/2001) to remove the
client_socket from the conn_rec. Diffs from Ryan's patch include:
- rename the create_connection hook to install_transport_filters
- move the point of invocation of the hook till after the call to
after ap_update_vhost_given_ip to enable the hook to use vhost
config info in its decision making.
BuildBin never made it to this home. Makefile.win got lost, since it
would have been invoked from another path, trying to validate that the
apr and apr-util repositories had been checked out. Too much trouble :)
By popular demand and some of my own observations - here is a build
target one can use as a dummy, without 'installing binaries'. Now
Win32's makefile.win will simply kick off BuildBin and let it fire
off all the targets from a command line build. This will help to
resolve some of the misses on incremental builds.

If the ftp proxy could not guess the output format of the ftp server's
directory listing, it makes another attempt: it tries a format similar to
the output of "ls -s1" (optional whitespace followed by size, followed by
whitespace, followed by filename, where filename may contain no more whitespace).
This format works at least with one FTP server for which previously only
the (non-clickable) output was displayed.

Don't let the default handler try to serve a raw directory. At
best you get gibberish. Much worse things can happen depending
on the OS.
This can happen when autoindex isn't loaded.
On AIX, I had a directory file which was reported to be 1536 bytes
in size. mmap() failed so we went to the fall-back logic.
The first read() got 624 bytes and the next read() got 0
(supposedly EOF). This confused us greatly, we kept allocating
buffers and reading and exercised the paging space.

Take advantage of the new pre_config return value when apr_proc_detach

Remove the create_connection hook and put the client_socket back into the
conn_rec. The create_connection_hook has a design flaw that prevents it
from making decisions based on vhost information.
Shortcut where the resource has no language [discovered with no
DefaultLanguage in cgi-bin, resolving Greg Ames' observations, we
had a lurking segfault.]
This begs the question, what exactly did the fn do with no language
in terms of serving content back in 1.3. Should be reviewed.
Which PR? I can't count them all. Get QUERY_STRING and PATH_INFO
working again. Also rounds out our fix to work around negotiated
directories which Greg Ames fixed; this addition in request.c simply
shortcuts all further processing.

Added new functions ap_add_input_filter_handle() and
ap_add_output_filter_handle()
There are many places in the core modules where we do
ap_add_input_filter() or ap_add_output_filter() on a
hardcoded filter name (e.g., "CORE" or "BYTERANGE").
This requires a string-to-filter mapping that wastes
CPU time. (Even though the string lookup uses a trie
for speed, it still ranks as a big consumer of CPU time
because of the large number of filters added per request.)
The new ap_add_*_filter_handle() functions will allow
us to skip the string-to-filter mapping in cases where
the module adding the filter happens to have the
ap_filter_rec_t* for the registered filter (e.g., because
it's the same module that registered the filter in the
first place).

No. I don't like this patch. I like what it does [shared scoreboard
for Windows, finally] but not how it's implemented.
However it works, and is equally crufty to what already exists for
win32 listeners and other exposed data within scoreboard.c.
To do this right, we need to drop all the external references to data
within the scoreboard, and add an accessor for remaining bits (such as
Win32's need for direct access to the apr_shm_t.) And within Win32,
we need to stack all this _within_ the pre-mpm hook. But those are
missions in and of themselves.
Change ap_get_brigade prototype to remove *readbytes in favor of readbytes.
If you need the length, you should be using apr_brigade_length. This is
much more consistent. Of all the places that call ap_get_brigade, only
one (ap_http_filter) needs the length. This makes it now possible to
pass constants down without assigning them to a temporary variable first.
Also:
- Change proxy_ftp to use EXHAUSTIVE mode (didn't catch its -1 before)
- Fix buglet in mod_ssl that would cause it to return too much data in
some circumstances

Fix some serious, hard-core breakage :-( I don't even know how it

* there is no UNIX symbol, so go back to #ifndef WIN32. that other
platforms can pile on as needed until we have a proper mechanism.
* reinstate the liveprop callbacks and the dav_hooks_liveprop_fs
structure. since the latter structure is referred to elsewhere in
the file, it better be defined.
* use a "feature" name of DAV_FS_HAS_EXECUTABLE rather than
conditionally specifying the property. convert the tests over to
that symbol.
Rewrite ap_rgetline to remove the need to have an "internal" brigade stored
in the core_module structure by using the AP_MODE_SPECULATIVE filter mode
to determine if MIME-continuation should occur.
Notes:
- ap_rgetline has a new prototype.
- ap_rgetline returns APR_ENOSPC when we are out of buffer space.
All direct callers of ap_rgetline are now adjusted to handle this new API.
ap_getline will mimic the old API for now.
Divorce dav_fs from the DAV_PROPID_FS_executable property at the
very head of this module, and drop all references as soon as we
determine that 'our property' isn't supported.
