This enables cross-compiling to set the php_cv_func_ttyname_r variable
for adjusting the configuration manually.
In case of cross-compiling the AC_CHECK_FUNCS is additionally used to
guess whether the target has the ttyname_r. Current platforms mostly
either have working ttyname_r compatible with POSIX or not.
The spl dependency is configured so the spl_autoload_register is
available when session_start() is used, meaning the spl extension needs
to be loaded before the session. It is marked as optional to be more
explicit as spl is not directly used nor required in the session
extension.
The session extension once depended on the hash extension for having
hash functions available when using the `session.hash_function` INI
directive. This directive was removed in PHP-7.1 via
3467526a65. At the time it could be marked
as optional dependency, because it only needed to be loaded before the
session in that case.
The removed ext/hash/php_hash.h in the ext/session/php_session.h might
cause BC break for PHP extensions if they rely on transitive include and
use hash extension in the code without explicitly including the
ext/hash/php_hash.h header. Solution is to include the
ext/hash/php_hash.h separately.
There's a hash table that maps type names to class name, but names with
a leading backslash are not supported. The engine has logic to strip
away the leading backslash that we should replicate here.
It works by checking if we need to make an actual copy in case an
unexpected (e.g. invalid data or leading backslash) situations are
detected. Upon making a copy we normalize the data in the table.
Furthermore, previously the code assumed that the key was always valid
and that the structure was a non-packed hash table. This isn't
necessarily the case. The new code fixes this as well.
Closes GH-14398.
This is a long standing bug: IDs aren't properly tracked causing either
outdated or plain incorrect results from getElementById.
This PR implements a pragmatic solution in which we still try to use the
ID lookup table to a degree, but only as a performance boost not as a
"single source of truth". Full details are explained in the
getElementById code.
Closes GH-14349.
There's a few leaks where the string is copied for lowercasing but not released.
Where possible, use the _lc functionality of zend_hash to do the lookup
to avoid the leaks that currently exist with the manual lowercasing.
Closes GH-14390.
Using PQSocketPoll to poll on a connection's socket.
Returns immediatly is there no event expected on read and write.
Other than that, it is a thin wrapper on top of poll, thus reflecting
its return value.
