Small fix for mod_env.html: The module was documented as to be _not_
compiled into Apache per default, although it _IS_ compiled into
Apache per default.
Two minor enhancements to mod_rewrite: First RewriteRule now also supports the
``nocase|NC'' flag (as RewriteCond already does for ages) to match case
insensitive (this especially avoids nasty patterns like `[tT][eE][sS][tT]').
Second two additional internal map functions `escape' and `unescape' were
added which can be used to escape/unescape to/from hex-encodings in URLs parts
(this is especially useful in combination with map lookups).

Fix a few minor inconsistencies related to directive scoping
============================================================
1. httpd -h
Under "httpd -h" one gets a nice English description in which scope a
directive can occur. But we talk here only about <Directory> and <Location>,
although <Files> is treated the same (also with `cmd->override ==
ACCESS_CONF|OR_ALL'). So I think it's correct to also list <Files>, too.
2. Used scope variants
Currently we have 203 directives and they use the following scopes (the
numbers in parenthesis gives the number of directives using a particular
scope):
The first one is just a syntax overkill. It means only OR_ALL, because OR_ALL
includes (implicitly) already RSRC_CONF and ACCESS_CONF. So, when we fix
this to OR_ALL we get:
The remaining RSRC_CONF|ACCESS_CONF|OR_AUTHCFG is used by two directives:
UseCanonicalName and ContentDigest. Two not too old directives which were
added mostly at the same time. They're are implemented the same way.
But the scope looks incorrect. Why?
First, it's again syntax overkill, ok. We can reduce it to
RSRC_CONF|OR_AUTHCFG. But when we compare it to all other used scopes, it
looks very inconsistent. No other of the 203 directives want to be applicable
in such a non-orthoginal scope: on the first hand inside the AuthConfig scope
(which means .htaccess under "AllowOverride AuthConfig" plus _INSIDE_ of
<Directory>/<Location>/<Files> sections in httpd.conf only) and on the other
hand also in RSRC_CONF (which means _OUTSIDE_ of
<Directory>/<Location>/<Files> sections in httpd.conf only). Sure, finally
it's everywhere in httpd.conf plus .htaccess under AuthConfig scope. But it's
not intuitive: Directives which want to be applicable in such a total scope
use OR_OPTIONS, OR_FILEINFO or OR_INDEXES. And when we think about
UseCanonicalName and ContentDigest we find out that they belongs more to
Options, XBitHack and CheckSpelling than to any AuthXXXX directives.
So, I propose to change the scope of those two directives to OR_OPTIONS. It
makes no big difference, of course. It still is useable everwhere inside
httpd.conf, but inside .htaccess now under Options instead of AuthConfig. And
it both belongs to the more correct group of directives and makes our list of
used scopes more consistent.
With the above patch be get this consistent scope-list:
When we take into account that _theoretically_ there are a lot more variants
of these or'ed values are possible, this list is _VERY_ clean. Actually it's
the most clean variant I can think of (except for the fact that the whole
mechanism is a horrible mess ;-)...
Cleanup the command line options: `-?' was documented to show the usage list
but does it with an error because `?' is not a valid command. OTOH a lot of
users expect `-h' to print such a usage list and instead are annoyed for ages
by our huge unreadable list of directives. So we now changed the command line
options this way:
1. `-L' => `-R'
Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
very similar to the popular linker option.
2. `-h' => `-L'
Intent: while -l gives the small list of modules, -L now gives the
large list of directives implemented by these modules. This is also
consistent with -v (short version info) and -V (large version info).
3. `-?' => `-h'
Intent: it's now the expected option ;-)
The manual page was adjusted accordingly.

Link DSO modules against possible libraries from $(LIBS) (take 2)
=================================================================
Currently we have the following entry in our dso.html document:
| Because DSO modules cannot be linked against other DSO-based libraries (ld
| -lfoo) on all platforms (for instance a.out-based platforms usually don't
| provide this functionality while ELF-based platforms do) you cannot use the
| DSO mechanism for all types of modules. Or in other words, modules compiled as
| DSO files are restricted to only use symbols from the Apache core, from the C
| library (libc) and all other dynamic or static libraries used by the Apache
| core, or from static library archives (libfoo.a) containing position
| independend code. The only chance to use other code is to either make sure the
| Apache core itself already contains a reference to it or loading the code
| yourself via dlopen().
The important part here is: "cannot be linked .... on all platforms". But
there _are_ platform (especially ELF-based ones) which support linking DSO
files agains other DSO files. And even on platforms where this is not
possible is it possible to at least link against libraries assuming they
contain PIC code.
So, the idea is this: In the configuration process we already determine the
variable LDFLAGS and LIBS. They hold -L and -l options for linking
executables. We parse these options and separate them into three classes:
OBJ, PIC and DSO. And then we re-assemble a LIBS_SHLIB variable from only the
options in classes PIC and DSO. This variable is then used on the build
command for mod_xxx.so.
Without SHARED_CORE the mod_auth_db.so cannot be linked or at least not loaded
correctly under run-time. With SHARED_CHAIN enabled it is linked against the
libdb.so and all is fine (at least under this ELF-based Debian box I tried):
This way we provide the maximum we can provide. Sure, on some platforms the
user still has no chance. But this shouldn't mean he becomes no chance on
other platforms where there _is_ a chance. So this patch is a first step for
more friendly and flexible DSO support.
The complete mechanism is triggered by a new Rule named SHARED_CHAIN. To avoid
problems this is DISABLED(!) for ALL(!) platforms currently. But when
experience shows that it worked fine for users we can enable it for tested
platforms per default.
Be more explicit when explaining how to compile from DSP files.
