openssl 0.9.8 in July 2005 first added pkg-config support, which is
earlier than the minimum supported version for php. This should
therefore be uiversally supported.
In f904830012, support for GNU Hurd was added to the opcache and
the configure check to ensure the opcache knows the flock struct
layout prior to building was changed check for two cases: BSD layout
and Linux layout. All the existing hard-coded cases in
ZendAccelerator.h follow these two cases, except for 64-bit AIX.
This means that even though building on 64-bit AIX would work,
the configure script refuses to continue.
Add a new configure check for the 64-bit AIX case and a new
compiler definition HAVE_FLOCK_AIX64. Now that all the cases are
covered, simplify the ifdef logic around these three HAVE_FLOCK_*
macros:
- The macOS and the various BSD flavors fall under HAVE_FLOCK_BSD
- Linux, HP-UX, GNU Hurd, 32-bit AIX, and SVR4 environments
fall under HAVE_FLOCK_LINUX
- 64-bit AIX falls under HAVE_FLOCK_AIX64
The only difference between the existing HAVE_FLOCK_LINUX and
the hard-coded Linux/HP-UX/Hurd case is that the latter
initialized the 5th member to 0, but since the C standard already
says that un-initialized members will be initialized to 0,
it's effectively the same.
The idea is to create an easy way to provide a certificate that never
expires. In order to make it cross-platform, PHP is used rather than
openssl CLI app. Using openssl to generate certificates for tests that
test openssl might be not the best idea but pros seem to outweight cons
that this "recursice dependency" adds
`_gdScaleHoriz()` and `_gdScaleVert()` may fail, but don't signal
failure since they are void functions. We change that according to
upstream libgd.
We also remove the unused `Scale()` function, which doesn't exist in
upstream libgd either, right away.
Previously this returned properties of a different object, including
INDIRECTs directly, which violates our invariants. Switch this to
only return properties for debugging purposes, without INDIRECTs.
If someone complains we can extend this to other purposes, as needed.
Add MUL back to the list and instead make the entire optimization
depend on IGNORE_OVERLOADING, which is there exactly so we can make
these kinds of assumptions.
