The file extension to mime type mapping *must* not depend on the file
extension's case for case-insensitive file systems, and *should* not
for case-sensitive file systems.
As of PHP 7.3.0, `sapi_cli_single_write()` is supposed to return `< 0`
on failure, but `fwrite()` returns a `size_t`, and signals error by
setting the stream's error indicator. We have to cater to that.
Since the member is not used in `OnUpdateEol()` that's not really an
issue, but still it's confusing to apparently have two INI settings
targeting the same member.
The `start` parameter of `php_cgi_ini_activate_user_config` is supposed
to hold the byte offset of the doc root in the given `path`. However,
the current expression which fixes a potential type incompatibility
will ever only evaluate to zero or one, because it uses the *logical*
and operator (`&&`). Furthermore we notice that subtracting one from
`doc_root_len` is not necessary, so there is even no need for the
`start` parameter at all.
This is the change from GH-5417 but for FPM. This was stripping the
last character from the doc_root. Given how it is used, this should
be harmless, but let's make it less confusing...
To retain legacy behavior I decided to add an option to control request
termination logic. If request_terminate_timeout_track_finished is set,
then request will be tracked for time limits even after
fastcgi_finish_request was called.
This patch depends on the fix provided in BUG 78469 (otherwise php-fpm
workers listening on named pipes on Windows will be erroneously terminated)
(PR #4636)
epoll event backend does not guarantee that child input/output events
are reported before SIGCHILD due to finished worker. While a bunch of
events received by epoll is being processed, child-related structures
may be removed before dispatching of an I/O event for the same child.
The result may be attempt to access to memory region allocated for
another purpose, segfault of the master process, and unavailable web
sites.
Postpone processing of SIGCHILD events till other events in the same
bunch are processed.

1. falls in an infinite loop because PHP engine's inconsistent state, now override the ITIMER_PROF to 0.1 second, clean shutdown must finish before that.
2. generate too much error log, we completely disable "error_reporting" before calling php_request_shutdown().
If TSRM is shut down and started again (something that phpdbg does),
then tsrmls_id needs to be reloaded everywhere. As tsrmls_id
update is a rare operation, doing that shouldn't be a problem.
