7c9d530b83a5b2469533e232ca7d5af508e03901Jakub Hrozek being involved? If not, why waste cycles trying to defend against

7c9d530b83a5b2469533e232ca7d5af508e03901Jakub Hrozek potential broken modules? It seems futile.

7c9d530b83a5b2469533e232ca7d5af508e03901Jakub Hrozek wrowe counters: no, it shouldn't happen unless the module is broken.

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose But the right answer is to fail the request up-front in dir/file

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose walk if the path was entirely invalid; and we can't do that either

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose or we break modules that are unwilling to hook map_to_storage.

7c9d530b83a5b2469533e232ca7d5af508e03901Jakub Hrozek * Rewrite core_output_filter. It is nearly impossible to support

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose * With AP_MODE_EXHAUSTIVE in the core, it is finally clear to me

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose how the Perchild MPM should be re-written. It hasn't worked

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose correctly since filters were added because it wasn't possible to

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose get the content that had already been written and the socket at

7c9d530b83a5b2469533e232ca7d5af508e03901Jakub Hrozek the same time. This mode lets us do that, so the MPM can be

7c9d530b83a5b2469533e232ca7d5af508e03901Jakub Hrozek fixed.

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose * The Add...Filter and Set...Filter directives do not allow the

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose administrator to order filters, beyond the order of filename (mime)

04feeade1f6259368a6b23c6b3ecbad261161659Sumit Bose extensions. It isn't clear if Set...Filter(s) should be inserted

before or after the Add...Filter(s) which are ordered by sequence of

filename extensions. At minimum, some sort of +-[0-10] syntax seems

like the quickest fix for a 2.0 gold release.

* Get perchild to work on platforms other than Linux. This

will require a portable mechanism to pass data and file/socket

descriptors between vhost child groups. An API was proposed

on dev@apr:

Message-ID: <20020111115006.K1529@clove.org>

* Try to get libtool inter-library dependency code working on AIX.

Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>

Justin says: If we get it working on AIX, we can enable this

on all platforms and clean up our build system

somewhat.

Jeff says: I thought I tested a patch for you sometime in

January that you were going to commit within a few

days.

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

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

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

through in the query string, however. Roy says the

original reason for disallowing it, from five years ago,

was to protect CGI scripts that applied PATH_INFO to

a filesystem location and which might be tricked by

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

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

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

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

allow it conditionally with a directive.

* FreeBSD, threads, and worker MPM. All seems to work fine

if you only have one worker process with many threads. Add

a second worker process and the accept lock seems to be

lost. This might be an APR issue with how it deals with

the child_init hook (i.e. the fcntl lock needs to be resynced).

More examination and analysis is required.

Status: This has also been reported on Cygwin.

Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)

Justin says: So, FreeBSD-CURRENT and Cywin have the same

problem. Yum. If another platform has this

with worker, this becomes a showstopper.

Aaron says: I spent some time disecting this and have come to

the conclusion that it is not a problem in the worker MPM

(or at least, it is not isolated to a problem in worker).

I'll list some of the problems I'm seeing in case someone

else wants to pick up where I've left off:

- Delivery of just about any signal to one of the child

processes will send it into an infinite loop as well.

- Even though the parent is spinning out of control,

at first the child or children will appear to work

properly. At times it is possible to get it into a state,

however, where a request will hang until another concurrent

request "kicks" the first, at which point the second will

hang. My theory is that this has to do with the

pthread_cond_*() implementation in FreeBSD, but it's still

possible that it is in APR.

Justin adds: Oh, FreeBSD threads are implemented entirely with

select()/poll()/longjmp(). Welcome to the nightmare.

So, that means a ktrace output also has the thread

scheduling internals in it (since it is all the same to

the kernel). Which makes it hard to distinguish between

our select() calls and their select() calls.

*bangs head on wall repeatedly* But, some of the libc_r

files have a DBG_MSG #define. This is moderately helpful

when used with -DNO_DETACH. The kernel scheduler isn't

waking up the threads on a select(). Yum. And, I bet

those decrementing select calls have to do with the

scheduler. Time to brush up on our OS fundamentals.

* There is increasing demand from module writers for an API

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

Reasons include sole-function servers that need to die if

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

Perhaps something in the (ever more abused) scoreboard?

rbb: I don't believe the scoreboard is the correct mechanism

for this. We already have a pipe that goes between parent

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

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

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

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

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

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

* 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.

* 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.

OtherBill asks, wasn't this fixed?

stoddard: Not fixed. 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.

* Win32: Add a simple hold console open patch (wait for close or

the ESC key, with a nice message) if the server died a bad

death (non-zero exit code) in console mode.

Resolution: bring forward same ugly hacks from 1.3.13-.20

This is not so simple. Any exit() from APR or other libraries

can't be caught unless we add some sort of apr_exit(rv) with

registered apr_atexit() fn's that have the return code as an

argument to the registered fn.

* Eliminate unnecessary creation of pipes in mod_cgid

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

Common logging API.

* Document mod_file_cache.

* 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.

* Win32: Migrate the MPM over to use APR thread/process calls. This

would eliminate some code in the Win32 branch that essentially

duplicates what is in APR.

* 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.

* 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)

* Win32: Get Apache working on Windows 95/98. The following work

(at least) needs to be done:

- Document warning that OSR2 is required (for Crypt functions, in

rand.c, at least.) This could be resolved with an SSL library, or

randomization in APR itself.

- Bring the Win9xConHook.dll from 1.3 into 2.0 (no sense till it

actually works) and add in a splash of Win9x service code.

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

of ap_os_killpg, regardless of how they should die. (Ryan Bloom)

* 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

TODO ISSUES REMAINING IN MOD_SSL:

* In order to use a DSO version of mod_ssl we have to link with

-lssl and -lcrypto. A workaround is in place right now where the

entire EXTRA_LIBS macro is being appended to the objects list, but

this is a hack. We should either revamp the APACHE_CHECK_SSL_TOOLKIT

autoconf function or come up with some other autoconf checks to

search for libssl and libcrypto and properly add them to mod_ssl's

link flags.

* SSL renegotiations in combination with POST request

* Port or dispose all code inside #if 0...#endif blocks that remain

from the porting effort.

* 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

* the shmcb code should just align its memory segment rather than

jumping through all the "safe" memcpy and memset hoops

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.

mod_cache/mod_mem_cache/mod_disk_cache:

* mod_cache: handle cache_control: no_cache "field_name" to enable

cacheing the response w/o header "field_name"

See RFC2616 section 14.9.1

* mod_cache: CacheEnable/CacheDisable should accept regular expressions.

* mod_cache: Fix dependency on ATOMIC operators. Need

APR_HAS_ATOMIC_* feature macros.

* mod_disk_cache: Implement garbage collection

* 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?

* mod_mem_cache: garbage collection. One strategy is to simply

remove stale entries as we attempt to serve them. Another

strategy is to kick off a GC thread that traverses the cache

and preemptively remove stale entries. How to manage a

cache that is full? Do LRU GC? Other? Bueller?

directives.

inclusion into httpd.conf.

Status: Cannot accept password-as-arg, we should prompt the

Other bugs that need fixing:

* ap_discard_request should be converted to use the bucket API

directly rather than waste cycles copying buffers with the old API.

* 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.

* SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a

sigwaiting thread. We need to work around this, perhaps unless

there is hope soon for a fixed glibc.

* 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 :-)
