Some editors utilizing .editorconfig automatically trim whitespaces. For
convenience this patch removes whitespaces in certain build files in
Zend and TSRM folders.
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.
The slower I/O as a traditional bottleneck on Windows which is
the target of this patch. The recursive path resolution, while being
an allround solution, is expensive when it comes to the common case.
Files with proper ACLs set can be resolved in one go by usage of specific
API. Those are available since Vista, so actually can be called old. Those
simpler api is used for the cases where no CWD_EXPAND is requested. For
the cases where ACLs are improper, the existing solution based on
FindFirstFile still does good job also partially providing quirks. Cases
involing reparse tags and other non local filesystems are also partially
server by new APIs.
The approach uses both APIs - the quick one for the common case still
integrating realpath cache, and the existing one as a fallback. The tests
show the I/O load drop on the realpath resolution part due to less
system calls for the sub part resolution of paths. In most case it is
justified, as the sub parts were otherwise cached or unused as well. The
realpath() implementation in ioutil is also closer to the POSIX.
If a C++11 source is compiled, thread_local is preferred. Furthermore,
at least GCC treats __thread vs. thread_local a different way and under
certain circumstances would refuse to compile __thread is a C++11 source.
This change is far behind in time, any up-to-date compiler supports C++11
and otherwise it won't take effect on lower versions.
This patch however does not drop support for the BeOS compatible variant, Haiku, see Github PR #2697 which is currently a WiP
I intentionally left out some fragments for BeOS in the build system for that seems to be bundles
Hereby, interned strings are supported in thread safe PHP. The patch
implements two types of interned strings
- interning per process, strings are not freed till process end
- interning per request, strings are freed at request end
There is no runtime interning.
With Opcache, all the permanent iterned strings are copied into SHM on
startup, additional copying into SHM might happen on demand.
configure.ac was introduced in 2001 with automake-1.15 and autoconf-2.50
to replace the file named configure.in.
Autotools is preparing to remove configure.in in Automake 2.0.
All new software should be using configure.ac.
This also fixes Bug #69770 where extensions are creating configure.in

Primarily related to the path handling datatypes, to avoid unnecessary
casts, where possible. Also some rework to avoid code dup. Probably
more places are to go, even not path related, primarily to have less
casts and unsigned integers where possible. That way, we've not only
less warnings and casts, but are also safer with regard to the
integer overflows. OFC it's not a panacea, but still significantly
reduces the vulnerability potential.
If this does not break the Unix system somehow, I'll be amazed. This should get most of it out, apologies for any errors this may cause on non-Windows ends which I cannot test atm.
Note: AC_TRY_LINK interprets the source as part of a main function, ending up with int main() { /* ... */ int main() { /* ... */ } ; return 0; } here - Using AC_LINK_IFELSE with AC_LANG_SOURCE directly instead.
pthreads are not working when cross-compiling, indeed configure
sets pthreads_working to no if cross_compiling is detected.
This behavior is implemented in PTHREADS_CHECK. This function call
AC_CACHE_CHECK twice to retrieve ac_cv_pthreads_cflags and
ac_cv_pthreads_lib.
In these calls, the function PTHREADS_CHECK_COMPILE will call AC_TRY_RUN
function which will update the global pthreads_working variable.
This is not compliant with autoconf AC_CACHE_CHECK rules which specify
that "The commands-to-set-it must have no side effects except for
setting the variable cache-id".
So, this patch replaces pthread_working assignments with assignments on
a new local pthread_checked variable. Value of ptreads_working is
computed outside AC_CACHE_CHECK function depending on value of
ac_cv_pthreads_cflags and ac_cv_pthreads_lib.
Moreover, AC_TRY_RUN call is replaced by AC_TRY_LINK which will work
when cross-compiling.
Without this modification, thread safety option (--enable-maintainer-zts)
can not be enabled on embedded buildsystems such as buildroot.
