The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
In PHP static properties are shared between inheriting classes,
unless they are explicitly overwritten. However, because this
functionality was implemented using reference, it was possible
to break the implementation by reassigning the static property
reference.
This is fixed by switching the implementation from using references
to using INDIRECTs, which cannot be affected by userland code.
This fixes the behavior when the storage location of the fetch is
modified before the operand is dereferenced by the using VM opcode.
Furthermore it elimiates references as a possible return value from
*_R opcodes, which will give us more opportunities for inferences,
in particular in regard to typed properties.
The macro properly has two matching `(` and `)` symbols
after this change.
This typo was causing syntax errors when compiling extensions
using the (deprecated) macro.
This fixes a bug in the PHP 7.3 branch introduced by
742d5a01ed
convert_scalar_to_number() will now call cast_object() with an
_IS_NUMBER argument, in which case the cast handler should return
either an integer or floating point number, whichever is more
appropriate.
Previously convert_scalar_to_number() unconditionally converted
objects to integers instead.
Fixes bug #53033.
Fixes bug #54973.
Fixes bug #73108.
New macro ZVAL_COPY_OR_DUP() is used perform duplication, if necessary.
This should eliminate related race-coditions in ZTS build and prevent reference-counting bugs after unclean shutdown.
* master:
Use per-request heap instead of system one
Extend zend_register_class_alias_ex() with additional argument to allow creating persistent or per-request aliases
Makrk persistent resources and references with GC_PERSISTENT flag
Prohibit direct update of GC_REFCOUNT(), GC_SET_REFCOUNT(), GC_ADDREF() and GC_DELREF() shoukf be instead.
Added mactros to validate reference-counting (disabled for now).
These macros are going to be used to eliminate race-condintions during reference-counting on data shared between threads.
