On x86_64 glibc memrchr() uses SSE/AVX CPU extensions and works much
faster then naive loop. On x86 32-bit we still use inlined version.
memrchr() is a GNU extension. Its prototype becomes available when
<string.h> is included with defined _GNU_SOURCE macro. Previously, we
defined it in "php_config.h", but some sources may include <string.h>
befire it. To avod mess we also pass -D_GNU_SOURCE to C compiler.
Requiring all internal classes (including those from 3rd-party
extensions) to implement Stringable if they provide __toString()
is too error prone. Case in point, our _ZendTestClass test class
was not doing so, resulting in preloading test failures after
recent changes.
Instead we automatically implement Stringable, the same as we do
for userland classes. We still allow explicit implementations,
but ignore them (normally they would result in an error due to
duplicate interface implementation). Finally, we need to be
careful about not trying to implement Stringable on Stringable
itself.
In some cases this changes the interface order, in particular the
automatic Stringable implementation will now come first.
- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values
Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)
TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.
As a followup to f34114b1fb print
the contents of arrays rather than just a generic "Array" marker.
Also drop the truncation on strings. As we no longer resolve
constants, there should be less concerns about printing very
large strings here. If someone thought it was a good idea to use
a 10k character strings as a default value in code, then it should
be fine for us to print it in reflection as well.

The main change is to store scoreboard procs directly to the variable sized
array rather than indirectly through the pointer.
