PHP 7.4 INTERNALS UPGRADE NOTES
- initial import, internals upgrade guide
2010-08-30 10:26:31 +00:00
1. Internal API changes
Create and expose php_sys_symlink() and php_sys_link() These macros are supposed to behave like POSIX's symlink() and link(), respectively, on POSIX compliant systems and on Windows. Future scope: merge link.c and link_win32.c
2018-08-02 12:08:30 +00:00
a. php_sys_symlink() and php_sys_link()
Change zend_lookup_class_ex() and zend_fetch_class_by_name() prototypes to accept optional lower-case class name as zend_string*, instead of zval*.
2018-08-22 14:07:31 +00:00
b. zend_lookup_class_ex() and zend_fetch_class_by_name()
Renumber ZEND_ACC_... flags
2018-09-11 14:21:17 +00:00
c. Function/property/class flags
Remove zend_check_private()
2018-09-13 10:47:06 +00:00
d. Removed zend_check_private()
- drop TSRMLS_FETCH in sapi_register_* (won't bring much at runtime :) ) and cleanup/group the upgrade guide, no need of twenty titles for the same change
2010-09-17 08:42:12 +00:00
- Added section for build system changes in UPGRADING.INTERNALS
2010-11-18 10:43:01 +00:00

2018-09-11 08:56:45 +00:00
- ZEND_ACC_SHADOW property flag is removed. Instead of creating shadow
clone, now we use the same private property_info, and should also
check property_info->ce (in the same way as with methods).
Replace ZEND_ACC_ANON_BOUND, ZEND_ACC_UNRESOLVED_PARENT and ZEND_ACC_UNRESOLVED_INTERFACES with single ZEND_ACC_LINKED.
2018-09-18 08:41:40 +00:00
- ZEND_ACC_ANON_BOUND is replaced with ZEND_ACC_LINKED. This flag is set
not only during anonymous classes declaration, but also during any
run-time or compile-time class declaration.

2018-09-11 14:21:17 +00:00

[ci skip] Update UPGRADING.INTERNALS
2018-09-21 14:27:51 +00:00
e. Pointers returned by php_win32_error_to_msg() have to be freed using
php_win32_error_msg_free(). Same regarding php_win_err() vs.
php_win_err_free().

2. Build system changes
========================
update UPGRADING.INTERNALS
2014-11-10 13:25:14 +00:00
a. Unix build system changes
Implement #64517: Add AC_ARG_PROGRAM macro The AC_ARG_PROGRAM Autoconf macro provides program name transformations when installing. This patch implements #64517 and prepares the implementation for the request #60518. In ./configure --help it additionally outputs --program-prefix=PREFIX, --program-suffix=SUFFIX and the upcoming --program-transform-name=PROGRAM option. Macro AC_ARG_PROGRAM is available since Autoconf 2.0 and needs to be called after the AC_CANONICAL_TARGET macro. Refs: - https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Transforming-Names.html
2018-08-25 18:52:28 +00:00
- configure --help now also outputs --program-suffix and --program-prefix
information by using the Autoconf AC_ARG_PROGRAM macro.
Remove AC_FUNC_UTIME_NULL Autoconf 2.59d (released in 2006) [1] started promoting several macros as not relevant for newer systems, including the AC_FUNC_UTIME_NULL. This macro checks if `utime(file, NULL)` sets file's timestamp to the current time and defines the `HAVE_UTIME_NULL` symbol. This check was relevant on very old systems (for example, 4.3BSD released in 1986) and today can be omitted for systems with utime since it should be well supported by now. [2] Refs: [1] http://git.savannah.gnu.org/cgit/autoconf.git/tree/NEWS [2] https://www.gnu.org/software/autoconf/manual/autoconf-2.69/autoconf.html
2018-09-01 01:56:52 +00:00
- Obsolescent macros AC_FUNC_VPRINTF and AC_FUNC_UTIME_NULL have been
removed. Symbols HAVE_VPRINTF and HAVE_UTIME_NULL are no longer defined
since they are not needed on the current systems.
update UPGRADING.INTERNALS
2014-11-10 13:25:14 +00:00
b. Windows build system changes
Update UPGRADING and UPGRADING.INTERNALS
2015-01-25 21:14:40 +00:00

3. Module changes
========================
Make ext/xml API private Also remove dead functions
2018-09-16 09:07:40 +00:00
a. ext/xml
- The public (internal) API of the ext/xml extension has been removed. All
functions and structures are private to the extension now.
