cb2846ded4de1abbb5934b92132baf826f1babfebnicholes There's at least one PR that suffers from the current unclean behaviour

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes (which lets the server send garbage): PR 17629

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes nd says: Every subrequest should get its own filter stack with the

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes subreq_core filter as bottom-most. That filter does two things:

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes - swallow EOS buckets

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes - redirect the data stream to the upper request's (rr->main)

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes filter chain directly after the subrequest's starting

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes order, but the second time, we don't sort them correctly. Currently,

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes the modules/http/config.m4 file has been renamed to

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes modules/http/config2.m4 to work around this problem, it should moved

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes OtherBill offers that this is a SERIOUS problem. We do not sort

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes correctly by the ordering arguments passed to the register hook

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes functions. This was proven when I reordered the open_logs hook

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes to attempt to open the error logs prior to the access logs. Possibly

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes the entire sorting code needs to be refactored.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes a bit clunky on some platforms; eg, on Linux, the loop to

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes join each worker thread seems to hang, and the parent ends up

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes killing off the child with SIGKILL. But at least it shuts down.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes potential broken modules? It seems futile.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes wrowe counters: no, it shouldn't happen unless the module is broken.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes But the right answer is to fail the request up-front in dir/file

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes * Handling of %2f in URIs. Currently both 1.3 and 2.0

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes completely disallow %2f in the request URI path (see

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes ap_unescape_url() in util.c). It's permitted and passed

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes through in the query string, however. Roy says the

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes original reason for disallowing it, from five years ago,

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes was to protect CGI scripts that applied PATH_INFO to

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes a filesystem location and which might be tricked by

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes ..%2f..%2f(...). We *should* allow path-info of the

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes form 'http://foo.com/index.cgi/path/to/path%2finfo'.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes Since we've revamped a lot of our processing of path

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes segments, it would be nice to allow this, or at least

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes allow it conditionally with a directive.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes OtherBill adds that %2f as the SECOND character of a multibyte

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes sequence causes the request to fail! This happens notably in

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes the ja-jis encoding.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes * There is increasing demand from module writers for an API

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes that will allow them to control the server � la apachectl.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes Reasons include sole-function servers that need to die if

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes an external dependency (e.g., a database) fails, et cetera.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes Perhaps something in the (ever more abused) scoreboard?

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes On the other hand, we already have a pipe that goes between parent

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes and child for graceful shutdown events, along with an API that

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes can be used to send a message down that pipe. In threaded MPMs,

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes it is easy enough to make that one pipe be used for graceful

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes and graceless events, and it is also easy to open that pipe

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes to both parent and child for writing. Then we just need to

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes figure out how to do graceless on non-threaded MPMs.

cb2846ded4de1abbb5934b92132baf826f1babfebnicholes * Allow the DocumentRoot directive within <Location > scopes? This

allows the beloved (crusty) Alias /foo/ /somepath/foo/ followed

by a <Directory /somepath/foo> to become simply

<Location /foo/> DocumentRoot /somefile/foo (IMHO a bit more legible

and in-your-face.) DocumentRoot unset would be accepted [and would

not permit content to be served, only virtual resources such as

server-info or server-status.

This proposed change would _not_ depricate Alias.

striker: See the thread starting with Message-ID:

JLEGKKNELMHCJPNMOKHOGEEJFBAA.striker@apache.org.

* Win32: Rotatelogs sometimes is not terminated when Apache

goes down hard. FirstBill was looking at possibly tracking the

child's-child processes in the parent process.

stoddard: Shared scoreboard might offer a good way for the parent

to keep track of 'other child' processes and whack them if the child

goes down.

Other thoughts on walking the process chain using the NT kernel

have also been proposed on APR.

* Eliminate unnecessary creation of pipes in mod_cgid

* Combine log_child and piped_log_spawn. Clean up http_log.c.

Common logging API.

* Platforms that do not support fork (primarily Win32 and AS/400)

Architect start-up code that avoids initializing all the modules

in the parent process on platforms that do not support fork.

* There are still a number of places in the code where we are

losing error status (i.e. throwing away the error returned by a

system call and replacing it with a generic error code)

* Mass vhosting version of suEXEC.

* All DBMs suffer from confusion in support/dbmmanage (perl script) since

the dbmmanage employs the first-matched dbm format. This is not

necessarily the library that Apache was built with. Aught to

rewrite dbmmanage upon installation to bin/ with the proper library

for predictable mod_auth_dbm administration.

Questions; htdbm exists, time to kill dbmmanage, or does it remain

useful as a perl dbm management example? If we keep it,

do we address the issue above?

* Integrate mod_dav.

Some additional items remaining:

- case_preserved_filename stuff

(use the new canonical name stuff?)

- find a new home for ap_text(_header)

- is it possible to remove the DAV: namespace stuff from util_xml?

* ap_core_translate() and its use by mod_mmap_static and mod_file_cache

are a bit wonky. The function should probably be exposed as a utility

function (such as ap_translate_url2fs() or ap_validate_fs_url() or

something). Another approach would be a new hook phase after

"translate" which would allow the module to munge what the

translation has decided to do.

Status: Greg +1 (volunteers)

* Explore use of a post-config hook for the code in http_main.c which

calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and

ap_sort_hooks() [to reduce the logic in main()]

* read the config tree just once, and process N times (as necessary)

* (possibly) use UUIDs in mod_unique_id and/or mod_usertrack

* (possibly) port the bug fix for PR 6942 (segv when LoadModule is put

into a VirtualHost container) to 2.0.

* shift stuff to mod_core.h

* callers of ap_run_create_request() should check the return value

for failure (Doug volunteers)

* Fix the worker MPM to use POD to kill child processes instead

of ap_os_killpg, regardless of how they should die.

chrisd: Is this done, by any chance? See r92598 and r93358.

* Scoreboard structures could be changed in the future such that

proper alignment is not maintained, leading to segfaults on

some systems. Cliff posted a patch to deal with this issue but

later recanted. See this message to dev@apr.apache.org:

Message-ID:

<Pine.LNX.4.44.0203011354090.16457-200000@deepthought.cs.virginia.edu>

* APXS either needs to be fixed completely for use when apr is out of tree,

or it should drop query mode altogether, and we just grow an

httpd-config or similar arrangement.

To quote a discussion in STATUS earlier:

thommay: this doesn't fix all the problems with apxs and out of

tree apr/apr-util, but it's a good start. There's still the

query cases; but I'm beginning to think that in these cases

the app should be querying ap{r,u}-config directly

deprecate -q: add htpd-config: gstein, pquerna, minfrin, pgollucci

TODO ISSUES REMAINING IN MOD_SSL:

* Do we need SSL_set_read_ahead()?

* the ssl_expr api is NOT THREAD SAFE. race conditions exist:

-in ssl_expr_comp() if SSLRequire is used in .htaccess

(ssl_expr_info is global)

-is ssl_expr_eval() if there is an error

(ssl_expr_error is global)

* SSLRequire directive (parsing of) leaks memory

* Diffie-Hellman-Parameters for temporary keys are hardcoded in

ssl_engine_dh.c, while the comment in ssl_engine_kernel.c says:

"it is suggested that keys be changed daily or every 500

transactions, and more often if possible."

* ssl_var_lookup could be rewritten to be MUCH faster

* CRL callback should be pluggable

* session cache store should be pluggable

* init functions should return status code rather than ssl_die()

* ssl_engine_pphrase.c needs to be reworked so it is generic enough

to also decrypt proxy keys

* output warning when allowing SSL v2.0 ? its so old

WISH LIST

* mod_proxy: Ability to run SSL over proxy gateway connections,

encrypting (or reencrypting) at the proxy.

* mod_cache: Handle ESI tags.

* mod_cache: Resolve issue of how to cache page fragements (or perhaps

-if- we want to cache page fragements). Today, mod_cache/mod_mem_cache

will cache #include 'virtual' requests (but not #include 'file'

requests). This was accomplished by making CACHE_IN a

CONTENT_SET-1 filter to force it to run before the SUBREQ_CORE

filter. But now responses cannot be cached that include the

effects of having been run through CONTENT_SET filters

(mod_deflate, mod_expires, etc). We could rerun all the

CONTENT_SET filters on the cached response, but this will not

work in all cases. For example, mod_expires relies on installing

the EXPIRATION filter during fixups. Contents served out of

mod_cache (out of the quick_handler) bypass -all- the request

line server hooks (Ryan really hated this. It is great for

performance, but bad because of the complications listed above).

mod_cache/mod_mem_cache/mod_disk_cache:

* mod_mem_cache: Consider adding a RevalidateTimeout directive to

specify time at which local cached content is to be revalidated

(ie, underlying file stat'ed to see if it has changed).

* mod_cache: CacheEnable/CacheDisable should accept regular expressions.

jerenkrantz says: Too slow. Get regexs away from speedy caches by

default. Introduce a new CacheEnableRegex if you want.

* mod_mem_cache/mod_disk_cache: Need to be able to query cache

status (num of entries, cache object properties, etc.).

mod_status could be extended to query optional hooks defined

by modules for the purpose of reporting module status.

mod_cache (et. al.) could define optional hooks that are called

to collect status. Status should be queryable by

HTTP or SNMP?

jerenkrantz says: Yawn. Who cares.

* MaxRequestsPerChild measures connections, not requests.

Until someone has a better way, we'll probably just rename it

"MaxConnectionsPerChild".

* Regex containers don't work in an intutive way

Status: No one has come up with an efficient way to fix this

behavior. Dean has suggested getting rid of regex containers

completely.

OtherBill suggests: We at least seem to agree on eliminating

the <Container ~ foo> forms, and using only

<ContainerMatch foo> semantics.

* orig_ct in the byterange/multipart handling may not be

needed. Apache 1.3 just never stashed "multipart" into

r->content_type. We should probably follow suit since the

byterange stuff doesn't want the rest of the code to see the

multipart content-type; the other code should still think it is

dealing with the <orig_ct> stuff.

Status: Greg volunteers to investigate (esp. since he was most

likely the one to break it :-)

EXPERIMENTAL MODULES:

Experimental modules should eventually be be promoted to fully supported

status or removed from the repository entirely (ie, the

'experiment' failed). This section tracks what needs to happen to

get the modules promoted to fully supported status.
