This allows consumers of just the CSPRNG to include a much smaller header. It
also allows to verify at a glance whether a source file might use non-secure
randomness.
This commit includes the new header wherever the CSPRNG is used, possibly
replacing the inclusion of php_random.h if nothing else is used, but also
includes it in the main php_random.h header for compatibility.
Somewhat related to 45f8cfaf10,
2b30f18708, and
b14dd85dca.
This syncs the installed sapi and extension headers on *nix and Windows
systems by installing only what is intended outside of php-src.
- ext/gd: without gd_arginfo.h and gd_compat.h
- ext/hash: php_hash_joaat.h and php_hash_fnv.h added also on Windows
installation; xxhash/xxhash.h added on both installations as it is
included in php_hash_xxhash.h; Include path for xxhash.h changed to
relative so the php_hash_xxhash.h can be included outside of php-src;
Redundant include flags removed
- ext/iconv: without iconv_arginfo.h
- ext/mysqli: mysqli_mysqlnd.h was missing on Windows
- ext/phar: php_phar.h was missing on Windows
- ext/sodium: php_libsodium.h was missing on *nix
- ext/xml: without xml_arginfo.h
- sapi/cli: cli.h was missing on Windows

Several session tests incidentally check the values of INI variables
like session.name and session.save_path. This isn't the point of the
tests, and it can cause spurious failures if (for example) you want to
override your temporary directory while testing. So here, we make the
expected output patterns more lenient.
In an MPM worker scenario we have 1 module, N threads. Each thread must
have their globals initialised. If we only initialise the filename
fields in MINIT, then the threads have an uninitialized value. If the
uninitialized value is not NULL, this leads to segfaults upon access.
Closes GH-11530.
* Note where a session was already started
Duplicated session starts can be annoying to debug. The error that
occurs when a session is already active doesn't tell you where it
was initialized, so figuring out the callsite involves manual
debugging to find it out.
This keeps track of the call site of session_start as a request
global, and frees at the end of the request. It should make it
easier to find these instances for PHP users.
The resulting message can look like:
Notice: session_start(): Ignoring session_start() because a session is already active (started from /home/calvin/src/php-src/inc.php on line 4) in /home/calvin/src/php-src/index.php on line 9
Fixes GH-10721
* Convert to using zend_string for session start location
* Fix leak with session start callsite filename
If this was already initialized, we'd forget it. Have shared free
between session_start and RSHUTDOWN.
* For sessions that are automatically started, note that
Easy to forget that you have this set, in which case, session start
is done at RINIT outside of user code. Because this config option
can't change at runtime, we can check for it and make the error
more specific if that's the case.
* sid can never be NULL because it was NULL-checked earlier
* Change namelen to size_t because it is always unsigned and less in size than size_t
* Remove redundant check on ser
It can't be NULL, and even if it could, the ser++ would be UB.
In SessionHandler::gc, we use a virtual call to PS(default_mod)->s_gc to
call the gc implementation. That return value is checked against
FAILURE (-1).
One of the call targets of PS(default_mod)->s_gc is ps_gc_files().
ps_gc_files() calls to ps_files_cleanup_dir(). The latter function has
some error checks and outputs a notice if something goes wrong. In cases
of errors, the function returns 0. This means that the check in
SessionHandler::gc will misinterpret this as a success and report that 0
files have been *successfully* cleaned up. Fix it by returning -1 to
indicate something *did* go wrong.
Closes GH-10644.
This was introduced in 3467526a65 and the
corresponding RFC gives some reasoning. However the CSPRNG being “not secure
enough” is not a thing and reading these extra bytes is just security theater:
If the CSPRNG would hypothetically be broken, then PHP’s session IDs are the
least of one’s concerns, because we already trust it in `random_bytes()` and
might generate long-term secrets using that.
* Unserialize: Migrate "Unexpected end of serialized data" to E_WARNING
* Unserialize: Migrate "Error at offset %d of %d bytes" to E_WARNING
* Unserialize: Migrate "%s is returned from __sleep() multiple times" to E_WARNING
* Add NEWS for “Promote unserialize() notices to warning”
The issue is that PS(mod)->s_validate_sid is always defined for user modules, thus we need to check that the actual callable is set
Add another regression test to ensure current working behaviour is not broken (which was by the previous incorrect fix)
Closes GH-9638
* Emit deprecation warnings when adding dynamic properties to classes during unserialization - this will become an Error in php 9.0.
(Adding dynamic properties in other contexts was already a deprecation warning - the use case of unserialization was overlooked)
* Throw an error when attempting to add a dynamic property to a `readonly` class when unserializing
* Add new serialization methods `__serialize`/`__unserialize` for SplFixedArray to avoid creating deprecated dynamic
properties that would then be added to the backing fixed-size array
* Don't add named dynamic/declared properties (e.g. $obj->foo) of SplFixedArray to the backing array when unserializing
* Update tests to declare properties or to expect the deprecation warning
* Add news entry
