As suggested by Ryan and OtherBill, change the way that
mod_charset_lite checks to see if its filter will be
added by another module. Now, we run our insert-filter
hook really last and look at the actual filter chain.
(Note that http runs even later but it doesn't currently
do anything which would interfere.)
Same as Jeff Trawick's patch [thank you!] only a tad faster, and error
out on the old Set{Input|Output}Filter onefilter twofilter syntax
(prior to this patch, only the last filter in a space seperated list
would be configured.)
* configure.in: added Cygwin specific APR_SETVARs.
* os/config.m4: added Cygwin specific values for $OS and $OS_DIR.
$OS_DIR will change to "cygwin" as soon as I get the DSO/DLL things
clean as with 1.3.20.
* support/logresolve.c: added OS specific #ifdef statement to define
h_errno as extern __declspec(dllimport); it's imported from the
cygwin1.dll itself.

fix ap_remove_output_filter; the recent change to use remove_any_filter made
it possible to wipe out the entire filter chain. and then when
ap_finalize_request_protocol was called, r->output_filters was NULL,

Changed syntax of Set{Input|Output}Filter. The list of filters
must be semicolon delimited (if more than one filter is given.)
The Set{Input|Output}Filter directive now overrides a parent
container's directive (e.g. SetInputFilter in <Directory /web/foo>
will override any SetInputFilter directive in <Directory /web>.)
This new syntax is more consistent with Add{Input|Output}Filter
directives defined in mod_mime. Also cures a bug in prior releases
where the Set{Input|Output}Filter directive would corrupt the
global configuration if the multiple directives were nested.

Since the mod_mime patch was applied, here is the rest of the patch to
introduce the ForceType and SetHandler [absolute references] directly
into the very top of the fixups phase. This means these will always
override _any_ mime module, not just mod_mime. Ergo, other mime modules
can continue to set charset, encodings, etc. Since these are globals,
they belong in the core.
This highlights a very serious drawback to the type_checker hook. By
using run first, a module that identifies _partial_ information (maybe
just the content type) won't pass the query on to other modules, like
mod_mime, that might further define the encoding or charset. The
type_checker hook should clearly become a run-all, and the modules should
decline if they see someone ahead of them answered a question they were
going to try to figure.
Which means - if type_checker becomes RUN_ALL - this new override hook
fn should become a type_checker again - and RUN_REALLY_FIRST, and let
other modules _choose_ not to override this election. (We can run it
again at the end, for a recount ;) Votes?

This is the same granularity of control as mod_mime gave to set handlers
(and now AddInputFilter and AddOutputFilter by extension) so this seems
entirely appropriate in the core as well. Options FileInfo is required
to change the processing behavior of files.
*) Modfied mod_mime to prevent mod_negotation from serving a multiview
of a 'handler' or 'filter', so that any filename extension that does
not contribute to the negotiated metadata can't be served without
an explicit request. E.g., if the .Z extension is associated with
an unzip filter, the user request somefile.Z.html, mod_negotiation
won't serve it. It can serve somefile.Z.html when somefile.Z is
requested, since the .Z extension is explictly requested, if the
.html extension is associated with ContentType text/html.
See changes for a complete description. Because (in the example) the
.Z extension doesn't affect negotiated behavior, the files index.html
and index.Z.html couldn't be distinguished, and the user would get an
error 406 NOT ACCEPTABLE, which is the _wrong_ answer.
Someone pointed out that we were running the images through the INCLUDE
filter. This fixes it, in a sort of hackish way.
I don't remember who noticed this, sorry :(
Version 1.338 of mod_mime also tightened the mod_negotiation behavior.

Introduces mod_mime AddInputFilter and AddOutputFilter filter ext syntax.
Significantly refactored the code to maintain single functions for the
add_extension_info hash and remove_extension_info table processing.
The AddInputFilter/AddOutputFilter could have been plural, as they accept
a semicolon delimited list of filters (e.g. you need to stack two different
filters based on a single extension.) I expect that the plural could
confuse users, though, as they might expect AddInputFilters foo bar var
to add foo and bar to the extension var, which it definately doesn't do!

The consensus now is that mod_include should just butt out of any decisions
about what to do with different request methods. It's true that mod_include
in 1.3.x did not allow POST, but back then it was a handler. Now it's a
filter and can be used to filter the output of dynamically generated responses,
even ones resulting from a POST request. So if mod_include is in the filter
stack, it should just blindly parse the brigade regardless of request method.
This still fixes the security problem, it just fixes it by being more flexible
rather than less so.

Clean up location_walk, so that this step performs a minimum
amount of redundant effort (it must be run twice, but it will no
longer reparse all <Location > blocks when the request uri

The location walk block is refactored, with some significant changes
in variable names for legibility. Cooler still, it uses pool data
instead of 'notes' for the important cache info :)
Note the patch builds the <Location > per dir config from _nothing_,
and then merges it into the per_dir_config. When the underlying
per_dir_config changes between passes, the location_walk can simply
tack back on this preconstruct onto the new per_dir_config.

either directory_walk flavor much more legible, since that phase

Fix a double-free condition when byterange requests are made on brigades
containing any bucket that cannot be copied natively (ie, pipe or socket
buckets).
Before, we were reading that bucket to morph it to a heap bucket and then
taking the str that heap bucket points to and placing it in a second,
completely separate heap bucket. That means we'd have two apr_bucket/
apr_bucket_heap pairs each with a refcount of 1 (rather than two apr_buckets
and a single apr_bucket_heap with a refcount of 2). str would then be
doubly-freed when the second of those two buckets was destroyed.
Commit this code before another patch becomes to difficult to follow.
This patch does one thing, it changes the root path "/" to reflect an
element count of Zero (0). directory_walk will always accept the zero
element (which sorts first, thankfully) on it's first go around.
So, Unix will accept "/" when it's parsing it's first element "/".
Dos/Win32 will accept "/" and "C:/" when they parse their first element,
"C:/". The root sorted first, so it behaves as users expect.
The syntax "//" or "//machine" will be depreciated for now, the user
needs to set up the extact "//machine/share/" that they want served
on Win32.
