It strikes me as awkward that a Zend API user needs to take care of
doing the engine's reference counting.
This fixes a memory overrun in a testcase. All ZEND_SET_* calls
should be correct now.
session_register("c");
unset($c);
$c = time();
If a user unsets a global session variable, it is not a reference
to a $_SESSION slot anymore.
During serialization, PHP 4.2 will not find the respective entry in
$_SESSION and fall back to the global sym table.
completely in PS(http_session_vars). This avoids bugs which are caused
by a lack of synchronization between the two hashes. We also don't need
to worry about prioritizing one of them.
Add session.bug_compat_42 and session.bug_compat_warn which are enabled
by default. The logic behind bug_compat_42:
IF bug_compat_42 is on, and
IF register_globals is off, and
IF any value of $_SESSION["key"] is NULL, and
IF there is a global variable $key, then
$_SESSION["key"] is set to $key.
The extension emits this warning once per script, unless told otherwise.
"Your script possibly relies on a session side-effect which existed until
PHP 4.2.3. Please be advised that the session extension does not consider
global variables as a source of data, unless register_globals is enabled.
You can disable this functionality and this warning by setting
session.bug_compat_42 or session.bug_compat_warn.
on the state of $_SESSION/$HTTP_SESSION_VARS. It does not look up
symbols in the global symbol table anymore.
This was achieved by actually planting references between every
$_SESSION["x"] and $x, not only when restoring a session, but also
when registering a session variable (in a register_globals=1 context).
Upon registering a new variable, this memory leak continues to show
up, regardless of register_globals.

Obviously, the newly allocated empty zval is not properly freed. If anyone
has any idea on how to fix that, please step forward.
Default directory for session data (if not specified) is same (platform-specific) directory used for temporary files.
This is backwards compatible and removes the need for explicitly specifying the session.save_path on Win32.

also fix an unconditional segfault in rshutdown due to efree'ing
a static char *.
remove remove_var, add reset_vars. move the function declarations
into the right header file.
@ and remove variables from the URL-Rewriter. (thies)
i have also modified the session module to use this - so it doesn't
need to fiddle with the output-system any more
