This has been introduced by 84b0d0faba.
Besides it causes runtime issues on POWER5 (and presumably later), the
implementation would expect this array to consist on 32-bit integers.
This has two advantages: If the string is already lowercase, we
do not need to copy it, and it will hopefully match the interned
string name of the hash, making the comparison more efficient.
* get_parent_class() argument is optional
* Mark array_filter() $callback as optional
* The $base of gmp_strval() is optional
* DateTime constructor also accepts zero arguments
* hash_update_file() stream context is optional
* xmlwriter_write_dtd_entity() $isparam argument is optional
This code was actually unused since its introduction, and since at
least the md5 implementation in the core was completely overhauled,
we're dropping the md5 and sha1 related stuff from ext/hash.
The php_stream_read() and php_stream_write() functions now return
an ssize_t value, with negative results indicating failure. Functions
like fread() and fwrite() will return false in that case.
As a special case, EWOULDBLOCK and EAGAIN on non-blocking streams
should not be regarded as error conditions, and be reported as
successful zero-length reads/writes instead. The handling of EINTR
remains unclear and is internally inconsistent (e.g. some code-paths
will automatically retry on EINTR, while some won't).
I'm landing this now to make sure the stream wrapper ops API changes
make it into 7.4 -- however, if the user-facing changes turn out to
be problematic we have the option of clamping negative returns to
zero in php_stream_read() and php_stream_write() to restore the
old behavior in a relatively non-intrusive manner.
The hash extension is always available since PHP-7.4. The symbol
HAVE_HASH_EXT is kept for BC reasons and removed in PHP-8.0.
This patch also removes the PHAR_HASH_OK since it is no longer
relevant.
Normalization include:
- Use dnl for everything that can be ommitted when configure is built in
favor of the shell comment character # which is visible in the output.
- Line length normalized to 80 columns
- Dots for most of the one line sentences
- Macro definitions include similar pattern header comments now
Optimizing compilers have an annoying tendency to throw out
memsets over data that they think aren't used anymore. Apply secure
zero-out in cases where this has potential to happen.
