used to return "" and not bool(false). It's not worth keeping it because
STR_FREE() and zval_dtor() always have to check for it and it slows down
the general case. In addition, it seems that empty_string has been abused
quite a lot, and was used not only for setting zval's but generally in
PHP code instead of "", which wasn't the intention. Last but not least,
nuking empty_string should improve stability as I doubt every place
correctly checked if they are not mistakenly erealloc()'ing it or
calling efree() on it.
NOTE: Some code is probably broken. Each extension maintainer should
check and see that my changes are OK. Also, I haven't had time to touch
PECL yet. Will try and do it tomorrow.
- [ main/safe_mode.h ] added new checkuid mode:
CHECKUID_ALLOW_ONLY_FILE: skips directory check if file check
fails
- [ ext/standard/dir.c ] changed php_checkuid() to use
CHECKUID_ALLOW_ONLY_FILE instead of CHECKUID_ALLOW_ONLY_DIR
- [ main/safe_mode.c ] added code for new checkuid mode
o Fixed Bug #12119: safe mode owner check can be bypassed with symlink
- [ main/safe_mode.c ] use VCWD_REALPATH to resolve destination
of symlink before trimming filename
o New Feature: safe_mode_include_dir (php.ini directive)
- Allows bypassing UID/GID checks when including files
from the directory in safe_mode_include_dir and its
subdirectories. (safe_mode must be on, directory must
also be in include_path or full path must be used when
including)
o Fixed Feature: safe_mode_gid (php.ini directive)
- Correctly check (and report) UID/GID bits on directories
o Changed include() fall back to scripts cwd implementation
- CWD added to the (local) search path in php_fopen_with_path()
instead of seperate case. [ main/fopen_wrappers.c ]
a gid check instead of a uid check.
@ - Add getmygid() and safe_mode_gid ini directive to allow safe mode to do
@ a gid check instead of a uid check. (James E. Flemer, Rasmus)
