Enable GitHub actions cancel-in-progress for PRs

Pushing many commits to a pull request in a short amount of time can stall the merge builds and also wastes energy unnecessarily. Enable concurrency to cancel workflows of old commits in pull requests. Generate a common group name for pull requests using github.event.pull_request.url with github.run_id as a fallback for branches, which is unique and always available.

/.m4: update main() signatures.

The next generation of C compilers is going to enforce the C standard more strictly:

https://wiki.gentoo.org/wiki/Modern_C_porting

One warning that will soon become an error is -Wstrict-prototypes. This is relatively easy to catch in most code (it will fail to compile), but inside of autoconf tests it can go unnoticed because many feature-test compilations fail by design. For example,

$ export CFLAGS="$CFLAGS -Werror=strict-prototypes" $ ./configure ... checking if iconv supports errno... no configure: error: iconv does not support errno

(this is on a system where iconv does support errno). If errno support were optional, that test would have "silently" disabled it. The underlying issue here, from config.log, is

conftest.c:211:5: error: function declaration isn't a prototype [-Werror=strict-prototypes] 211 | int main() {

This commit goes through all of our autoconf tests, replacing main() with main(void). Up to equivalent types and variable renamings, that's one of the two valid signatures, and satisfies the compiler (gcc-12 in this case).

Fixes GH-10751

ext/iconv/config.m4: add missing stdio.h include.

The next generation of C compilers is going to enforce the C standard more strictly:

https://wiki.gentoo.org/wiki/Modern_C_porting

One warning that will eventually become an error is -Wimplicit-function-declaration. This is relatively easy to catch in most code (it will fail to compile), but inside of autoconf tests it can go unnoticed because many feature-test compilations fail by design. For example,

AC_LINK_IFELSE([AC_LANG_PROGRAM([[#include <iconv.h>]], [[iconv_ccs_init(NULL, NULL);]])]...

is designed to fail if iconv_ccs_init() is not in iconv.h. On the other hand,

AC_RUN_IFELSE([AC_LANG_SOURCE([[ #include <iconv.h> int main() { printf("%d", _libiconv_version); return 0; }

should pass if _libiconv_version is defined. If the user has -Werror=implicit-function-declaration in his CFLAGS, however, it will not:

$ export CFLAGS="$CFLAGS -Werror=implicit-function-declaration" $ ./configure ... checking if using GNU libiconv... no

This is because the stdio.h header that defines printf() is missing:

conftest.c:240:3: error: implicit declaration of function 'printf' [-Werror=implicit-function-declaration] 240 | printf("%d", _libiconv_version); | ^~~~~~ conftest.c:239:1: note: include '<stdio.h>' or provide a declaration of 'printf'

This commit adds the include, correcting the test with any compiler that balks at implicit function definitions.

Closes GH-10751

Fix GH-8646: Memory leak PHP FPM 8.1

Fixes GH-8646 See https://github.com/php/php-src/issues/8646 for thorough discussion.

Interned strings that hold class entries can get a corresponding slot in map_ptr for the CE cache. map_ptr works like a bump allocator: there is a counter which increases to allocate the next slot in the map.

For class name strings in non-opcache we have:

• on startup: permanent + interned
• on request: interned For class name strings in opcache we have:
• on startup: permanent + interned
• on request: either not interned at all, which we can ignore because they won't get a CE cache entry or they were already permanent + interned or we get a new permanent + interned string in the opcache persistence code

Notice that the map_ptr layout always has the permanent strings first, and the request strings after. In non-opcache, a request string may get a slot in map_ptr, and that interned request string gets destroyed at the end of the request. The corresponding map_ptr slot can thereafter never be used again. This causes map_ptr to keep reallocating to larger and larger sizes.

We solve it as follows: We can check whether we had any interned request strings, which only happens in non-opcache. If we have any, we reset map_ptr to the last permanent string. We can't lose any permanent strings because of map_ptr's layout.

Closes GH-10783.

Fix GH-8065: opcache.consistency_checks > 0 causes segfaults in PHP >= 8.1.5 in fpm context

Disable opcache.consistency_checks.

This feature does not work right now and leads to memory leaks and other problems. For analysis and discussion see GH-8065. In GH-10624 it was decided to disable the feature to prevent problems for end users. If end users which to get some consistency guarantees, they can rely on opcache.protect_memory.

Closes GH-10798.

Fix GH-10248: Assertion `!(zval_get_type(&(*(property))) == 10)' failed.

The assertion failure was triggered in a debug code-path that validates property types for internal classes. zend_verify_internal_read_property_type was called with retval being a reference, which is not allowed because that function eventually calls to i_zend_check_property_type, which does not expect a reference. The non-debug code-path already takes into account that retval can be a reference, as it optionally dereferences retval.

Add a dereference in zend_verify_internal_read_property_type just before the call to zend_verify_property_type, which is how other callers often behave as well.

when using it e.g. in a background job.

Background jobs should not run within the ACP. This PR is likely correct, but that explanation does not fit.

Also it would likely make sense to call pool_gc(p->table->pool) instead of pool_gc(NULL) so that it only tries to release the current table's pools and not all pools, since the other ones have no reason for being affected by the previous operation.

I've seen the fix committed (thanks!), but this was apparently not yet done. Mentioning to make sure it isn't accidentally overlooked.

Very strange, we don't see malloc_trim() here

That output is from strace, thus syscalls only. I don't expect to see malloc_trim there.

Do you use sticktables on one of your proxies?

Yes: https://www.haproxy.com/user-spotlight-series/using-haproxy-peers-for-real-time-quota-tracking/ :smile:

Does it last for a few seconds or for as long as it takes for the old process to exit?

The above snapshots were from a process that was soft-stopping for several hours by then. Here's another one. 2225288 is stopping for roughly 10 hours and only has a few connections left.

This issue is not actionable, because it lacks the necessary information to debug it. The error message is part of an intentional check:

https://github.com/WoltLab/WCF/blob/6d269e22eaa69e3fc993ab97e9ca3aaa697b96c8/wcfsetup/install/files/lib/system/package/PackageInstallationDispatcher.class.php#L483

Consider dumping both of the values that are compared within the if() condition. This will reveal how they are different.

@orlitzky You could probably just cat the config.log by adding it to the failing entry in push.yml after the config step.

@iluuu1994 Should we add that as a step to all CI by default? It would automatically be collapsed anyway. Alternatively it could be uploaded as an artifact.

Detailed Description of the Problem

This effectively is a follow-up for #1874. Once the health checks and DNS lookups were no longer running, I noticed that old workers still require a non-trivial amount of CPU, despite just handling single-digit numbers of almost-idle connections.

### Expected Behavior

I expected HAProxy to trim down memory usage once when stopping. Or possible whenever another connection exits, but not several times per second.


### Steps to Reproduce the Behavior

1. Look at a stopping worker process with `perf` and/or `strace`.

Update esbuild

Update the CKEditor 37 Alpha

I was on Vacation last week, but a co-worker performed the update to 2.7.5 last week. It's much better now: The number of of DNS queries per second is now pretty much constant and was reduced by approximately 90%. Thank you!

Old workers are still pretty busy with a large number of madvise(?, ?, MADV_DONTNEED) calls which looks wrong, but that's something for a different issue.

Picked into 5.4, thank you.
