* Remove free_chunk APINikita Popov2021-02-231-30/+1
| | | | | | This API only works in very limited circumstances -- relying on it will invariably lead to leaks. The correct way to "free" something from the pool is to use the checkpoint API.

| * Fix bug #78525Nikita Popov2019-09-131-0/+3
| | | | | | | | | | | | | | When calling free_result_buffers(), also free field metadata and restore the mempool state to what it was before any allocations have been made. Remove the mempool save/restore logic for the inner result set as this is now handled on a higher level.

| | | | | | | | | | We have to ensure that we don't create an arena which is smaller than its header, regardless of the configured alignment.

* | Add tracked arena allocatorNikita Popov2019-06-281-81/+15
| | | | | | | | | | | | | | | | | | | | Available under -DZEND_TRACK_ARENA_ALLOC. This will use the system allocator combined with arena checkpointing & release semantics and allows analyzing arena usage under asan/valgrind. I've sacrificed the duplicate arena implementation in mysqlnd, as the integration with mysqlnd alloc is not worth the code duplication to me.
* | Update and fix remaining year ranges (2019)Peter Kokot2019-02-081-1/+1
| | | | | | | | | | | | This patch follows previous license year ranges updates. With new approach source code files now have simplified headers with license information without year ranges.
* | Remove local variablesPeter Kokot2019-02-031-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the so called local variables defined per file basis for certain editors to properly show tab width, and similar settings. These are mainly used by Vim and Emacs editors yet with recent changes the once working definitions don't work anymore in Vim without custom plugins or additional configuration. Neither are these settings synced across the PHP code base. A simpler and better approach is EditorConfig and fixing code using some code style fixing tools in the future instead. This patch also removes the so called modelines for Vim. Modelines allow Vim editor specifically to set some editor configuration such as syntax highlighting, indentation style and tab width to be set in the first line or the last 5 lines per file basis. Since the php test files have syntax highlighting already set in most editors properly and EditorConfig takes care of the indentation settings, this patch removes these as well for the Vim 6.0 and newer versions. With the removal of local variables for certain editors such as Emacs and Vim, the footer is also probably not needed anymore when creating extensions using ext_skel.php script. Additionally, Vim modelines for setting php syntax and some editor settings has been removed from some *.phpt files. All these are mostly not relevant for phpt files neither work properly in the middle of the file.

| | | | | | | | | | | | | | | | Fix two problems: - The value of mysqli_get_client_info() has been changed recently and did not include "mysqlnd" anymore thus the test suite was thinking the build is always libmysql. This did not kept the suite from running pconn tests - Going back to the libc allocator because the memory arena could be on a persistent connections. If the build is not debug there will be no error but the memory will be freed and in the second use of this pconn freed memory will be used - not good! For now the arena doesn't take an argument whether it should allocate persistently or not, thus persistent is safe for now. Johannes gave his +1 to commit this.

| | | | | | | | | | Hardwire function call instead of using callbacks. We don't actually need callbacks, it was done for making 2 functions static, not to pollute the global functions space but that had its price of 8 bytes overheat per allocation, which is just too much. Also making the app member 32b instead of 64b, which should save additional 4 byte, to the total of 12 byte per allocation of a row buffer.
