* tree-wide: Replace `CHECK_NULL_PATH()` by `zend_char_has_nul_byte()`
The former is a direct alias of the latter with a more explicit name and the
former is explicitly documented as a “compatibility” alias.
* tree-wide: Replace `CHECK_ZVAL_NULL_PATH()` by its definition
The former is explicitly documented as a “compatibility” alias.
* zend_API: Remove `CHECK*NULL_PATH`
The `CHECK_ZVAL_NULL_PATH()` macro is unsafe, because it implicitly assumes
that the given `zval*` is `IS_STRING`.
Based on a GitHub search there does not seem to be any user outside of PHP, all
hits were just forks / copies of php-src.
* Include from build dir first
This fixes out of tree builds by ensuring that configure artifacts are included
from the build dir.
Before, out of tree builds would preferably include files from the src dir, as
the include path was defined as follows (ignoring includes from ext/ and sapi/) :
-I$(top_builddir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/main
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
-I$(top_builddir)/
As a result, an out of tree build would include configure artifacts such as
`main/php_config.h` from the src dir.
After this change, the include path is defined as follows:
-I$(top_builddir)/main
-I$(top_builddir)
-I$(top_srcdir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
* Fix extension include path for out of tree builds
* Include config.h with the brackets form
`#include "config.h"` searches in the directory containing the including-file
before any other include path. This can include the wrong config.h when building
out of tree and a config.h exists in the source tree.
Using `#include <config.h>` uses exclusively the include path, and gives
priority to the build dir.
* Mark many functions as static
Multiple functions are missing the static qualifier.
* remove unused struct sigactions
struct sigaction act, old_term, old_quit, old_int;
all unused.
* optimizer: minXOR and maxXOR are unused
These were once used in these files but at this point aren't and are
only causing confusion whether file depends on additional extension.
- locale.h is added in main/SAPI.c for _ENABLE_PER_THREAD_LOCALE
* PHP-8.2:
Fix GH-12223: Entity reference produces infinite loop in var_dump/print_r
Fix GH-12192: SimpleXML infinite loop when getName() is called within foreach
Fix GH-12186: segfault copying/cloning a finalized HashContext
* PHP-8.1:
Fix GH-12223: Entity reference produces infinite loop in var_dump/print_r
Fix GH-12192: SimpleXML infinite loop when getName() is called within foreach
Fix GH-12186: segfault copying/cloning a finalized HashContext
Nothing new but to refactor usage b/w hash and password
extensions but using volatile pointers to be a bit safer,
allowing to expand its usage eventually.
We must not allow to serialize already finalized `HashContext`s, since
the internal context is already freed. Since there is not much point
in serializing finalized `HashContext`s, we just bail out in that case.
Closes GH-8265.
- 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.
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.
4. fixed indentation in some files before |
We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
The implementation bundles the xxHash v0.8.0 release and includes all the variants
- xxh32, 32-bit wide
- xxh64, 64-bit wide
- xxh3, 64-bit wide
- xxh128, 128-bit wide
An initial hash state can be passed through the options arrray. An additional
functionality not targeted in this implementation is the secret support in xxh3
and xxh128. That can be added at a later point.
The serialization for xxh3 and xxh128 should not be implemented, as the
state would contain the secret. Despite the xxHash is a non crypto
algorithm, the secret would be serialized as plain text which would be
insecure.
Closes GH-6524

The concrete need on this change is to support passing an initial seed
to the murmur hash. Passing a custom seed is important in terms of
randomizing the hash function.
The suggested implementation adds a HashTable parameter to all the
init callbacks. Further on, an array with custom arguments is accepted
from `hash` or `hash_init` from the user land. Currently several things
like `hash_hkdf` are not touched, as they don't need passing custom
args.
Some convenience macros have been added to the SHA/MD families of
functions, so the consuming code doesn't have to be changed widely.
Another way to implement this is to add another type of the init that
would accept a HT with arguments. However, that would still require
touching all the context structs in all the algos. That would also
increase the size of those structs. As an init function is called just
once, the way of modifying the existing init callback has been seen
as more preferrable.
Closes GH-6400.

The implementation is based on the upstream PMurHash. The following
variants are implemented
- murmur3a, 32-bit hash
- murmur3c, 128-bit hash for x86
- murmur3f, 128-bit hash for x64
The custom seed support is not targeted by this implementation. It will
need a major change to the API, so then custom arguments can be passed
through `hash_init`. For now, the starting hash is always zero.
