* | | Remove unused Git attributes identPeter Kokot2018-07-251-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | consumption and avoid race condition during resolving/caching of user iterator functions of internal classes in ZTS build.

| | | | | | | | | | | | zend_class_entry.trait_precedences to avoid keeping "intermediate" trait references, that are used only during inheritance.

* | | Fixed ZTS race condition (zend_class_entry->ce_flags of internal classes ↵Dmitry Stogov2018-06-271-1/+0
| | | | | | | | | | | | must not be modified, because internal class enties are shared between threads)

| | | | | | | | | | | | | | | | | | at runtime) Run-time cache is used to eliminate recalculation of constant expression in RECV_INIT opcode (only non reference countable values are cached).

| | | | | | | | | | | | | | | Instead of moving live ranges around to maintain the start opnum invariant, add an explicit sorting step in pass two.

| | | | | | | | | | | | | | | | | | | | | properties and constants of internal classes). 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.

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.

| | | | | | | | | | | This means we no longer allocate an unused VAR for the retval of instructions that support unused results. Nearly all instructions already used the result variable only if it was used. The only exception to this was the return value variable for internal function call results. I've adjusted the code to use a stack zval for the unused return case now. As we have retval specialization now, we know that it doesn't matter.
