This issue might happen if there is change of the fcgi stream when
the buffer is full. Then the empty record is created which signals
end of stream which is incorrect.
The actual fix without a test was contributed by GitHub user @loveharmful
in GH-3198.
fcgi_accept_request function is supposed to call a FastCGI implementation's
on_accept hook when entering an "accepting" stage (that is right before
calling "accept"). This hook implementation (fpm_request_accepting) updates
a worker state to an "accepting" state which is effectively an "Idle" state,
and updates counters on the scoreboard of the corresponding pool (idle++,
active--).
But this is not done when listening for client connections on a named pipe on
Windows platform. In that case a combination of
ConnectNamedPipe/WaitForSingleObject is used (to be able to catch in_shutdown
as far as I understand), but it is nonetheless functionally equivalent to
"accept" call. Also by not calling on_hook neither a worker's state is updated
to "accepting" state nor scoreboard counters are updated.
This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.
A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.
This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.
With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.
Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
musl libc is complaining when <sys/poll.h> is used instead of <poll.h>
so change this.
This issue was reported for OpenWrt/LEDE where musl libc is the standard
C library instead of e.g. glibc, see the following link for the original PR:

v2: rebased to resolve merge conflict in main/php_network.h
v1: initial PR
As fcgi_request is an opaque struct as of PHP 7, expose a new API
function fcgi_end() which does fcgi_flush() with end=1 and checks/
sets the ->ended flag.
"closed" refers to whether FCGI_END_REQUEST has been sent, while
the "close" operation does something entirely different. It gets
extra confusing when fcgi_is_closed() does not actually return
fcgi_request.closed...
Previously fcgi_request defined in main/fastcgi.h might be treated differently in different files, because of different behavior of #ifdef TCP_NODELAY. This leaded to stack memory corruption and unpredictable crashes.
