directive
Trying to start PHP-FPM with the --allow-to-run-as-root flag will not
work when the user directive is not given in the FPM worker pool
configuration. Parsing the config will fail. Consequently, FPM cannot
start.
The check is in place to prevent FPM from getting started with root
privileges by accident. Prior to #61295 the check would also prevent
any non-root user to start PHP-FPM without a user directive present.
This patch adds an additional check to the config parser, checking for
the --allow-to-run-as-root flag to be present. If so, parsing will no
longer abort for root users even if the user directive is missing.
I will also update the PHP docs since they still state the user
directive is a mandatory setting which it is not since #61295.
This mainly involves a separate abstraction layer for elements (e.g. $a->b) and watchpoints (on pointer of the Bucket for example).
Also better comparison handling (value backup vs. page dumps).
It is not yet finished (there are sometimes false positives announced and names not yet perfect), but the functionality is working and not crashing as far as I have tested.
Future scope is also relative watchpoints, e.g. "w $this->val expression()" which does not have the symbol tables as basis, but the value (in this example: return value of expression()) as basis.
All existing systems zero anonymously mmapped memory, and if I
understand correctly POSIX will be specifying this soon. Many projects
already rely on it, so no reasonable system would return memory of
unspecified value.
Since long the default PHP charset is UTF-8, however the Windows part is
out of step with this important point. The current implementation in PHP
doesn't technically permit to handle UTF-8 filepath and several other
things. Till now, only the ANSI compatible APIs are being used. Here is more
about it

The patch fixes not only issues with multibyte filenames under
incompatible codepages, but indirectly also issues with some other multibyte
encodings like BIG5, Shift-JIS, etc. by providing a clean way to access
filenames in UTF-8. Below is a small list of issues from the bug tracker,
that are getting fixed:

Yet more related tickets can for sure be found - on bugs.php.net, Stackoverflow
and Github. Some of the bugs are pretty recent, some descend to early
2000th, but the user comments in there last even till today. Just for example,
bug #30195 was opened in 2004, the latest comment in there was made in 2014. It
is certain, that these bugs descend not only to pure PHP use cases, but get also
redirected from the popular PHP based projects. Given the modern systems (and
those supported by PHP) are always based on NTFS, there is no excuse to keep
these issues unresolved.
The internalization approach on Windows is in many ways different from
UNIX and Linux, while it supports and is based on Unicode. It depends on the
current system code page, APIs used and exact kind how the binary was compiled
The locale doesn't affect the way Unicode or ANSI API work. PHP in particular
is being compiled without _UNICODE defined and this is conditioned by the
way we handle strings. Here is more about it
https://msdn.microsoft.com/en-us/library/tsbaswba.aspx
However, with any system code page ANSI functions automatically convert
paths to UTF-16. Paths in some encodings incompatible with the
current system code page, won't work correctly with ANSI APIs. PHP
till now only uses the ANSI Windows APIs.
For example, on a system with the current code page 1252, the paths
in cp1252 are supported and transparently converted to UTF-16 by the
ANSI functions. Once one wants to handle a filepath encoded with cp932 on
that particular system, an ANSI or a POSIX compatible function used in
PHP will produce an erroneous result. When trying to convert that cp932 path
to UTF-8 and passing to the ANSI functions, an ANSI function would
likely interpret the UTF-8 string as some string in the current code page and
create a filepath that represents every single byte of the UTF-8 string.
These behaviors are not only broken but also disregard the documented
INI settings.
This patch solves the issies with the multibyte paths on Windows by
intelligently enforcing the usage of the Unicode aware APIs. For
functions expect Unicode (fe CreateFileW, FindFirstFileW, etc.), arguments
will be converted to UTF-16 wide chars. For functions returning Unicode
aware data (fe GetCurrentDirectoryW, etc.), resulting wide string is
converted back to char's depending on the current PHP charset settings,
either to the current ANSI codepage (this is the behavior prior to this patch)
or to UTF-8 (the default behavior).
In a particular case, users might have to explicitly set
internal_encoding or default_charset, if filenames in ANSI codepage are
necessary. Current tests show no regressions and witness that this will be an
exotic case, the current default UTF-8 encoding is compatible with any
supported system. The dependency libraries are long switching to Unicode APIs,
so some tests were also added for extensions not directly related to streams.
At large, the patch brings over 150 related tests into the core. Those target
and was run on various environments with European, Asian, etc. codepages.
General PHP frameworks was tested and showed no regressions.
The impact on the current C code base is low, the most places affected
are the Windows only places in the three files tsrm_win32.c, zend_virtual_cwd.c
and plain_wrapper.c. The actual implementation of the most of the wide
char supporting functionality is in win32/ioutil.* and win32/codepage.*,
several low level functionsare extended in place to avoid reimplementation for
now. No performance impact was sighted. As previously mentioned, the ANSI APIs
used prior the patch perform Unicode conversions internally. Using the
Unicode APIs directly while doing custom conversions just retains the status
quo. The ways to optimize it are open (fe. by implementing caching for the
strings converted to wide variants).
The long path implementation is user transparent. If a path exceeds the
length of _MAX_PATH, it'll be automatically prefixed with \\?\. The MAXPATHLEN
is set to 2048 bytes.
Appreciation to Pierre Joye, Matt Ficken, @algo13 and others for tips, ideas
and testing.
Thanks.
These are either in debug code (fix them), commented out (drop
them) or in dead compatibility macros (drop them).
One usage was in php_stream_get_from_zval(), which we have not used
since at least PHP 5.2 and, judging from the fact that nobody
complained about it causing compile errors in PHP 7, nobody else
uses it either, so drop it.
There are still remaining uses in mysqli embedded and odbc birdstep.
These probably need to be dropped outright.

This addresses bug #71269.
When an fpm child handles more than one request, zend_signal_startup() will
override the saved signal handlers with the internal zend handlers set from the
previous request, causing a SIGQUIT signal to result in a core dump rather than
gracefully exiting (the expected behaviour).
This is fixed by adding a call to zend_signal_init() after setting the
signal handlers in the child. The same technique is used in the apache SAPI
module in commit fd5a756ad4 which addresses
bug #61083.
--enable-phpdbg is not detected on old systems (e.g.: stock FreeBSD 8), due to a PHPism in config.m4 (use of == operator).
Replacing == with the historic = makes it pass.
PHP_FCGI_CHILDREN number of children processes will be spawned, sharing

- children cleanup on exit
- automatic children re-spawning

The global section is named "General", but the correct section name is "global". It is "global" in #1313 and also "global" in https://github.com/php/php-src/blob/master/sapi/fpm/php-fpm.conf.in. The commit fixes the naming. However, the proposed change might break any tooling that relies on finding "General" in the output though.
