This reverts commit 94ee4f9834.
The commit was a bit too late to be included in PHP 8.2 RC1. Given it's a massive ABI break, we decide to postpone the change to PHP 8.3.
Switch the recursion check from the result of `get_properties_for`
(the returned hash table of properties) to just checking for
infinite recursion on the object.
- In order for a native datastructure to correctly implement
`*get_properties_for` for var_export's cycle detection,
it would need to return the exact same array every time prior to this PR.
Prior to this commit, the requirements for cycle detection
would prevent SplFixedArray or similar classes from returning a
temporary array that:
1. Wouldn't be affected by unexpected mutations from error handlers
2. Could be garbage collected instead.
* 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

Given that Windows ignores trailing dots and spaces in filenames, we
catch that ourselves to avoid confusion with the respective filenames
without these characters.
Closes GH-9229.
This PR changes the glob stream wrapper so it impacts "glob://"
streamsas well. The idea is to do a check for each found path instead
of the pattern which was not working correctly.
One may argue that `DROP_NEW_LINE` does not make sense in combination
with `READ_CSV`, but without `DROP_NEW_LINE`, `SKIP_EMPTY` does not
skip empty lines at all. We could fix that, but do not for BC reasons.
Instead we no longer drop newlines in `spl_filesystem_file_read_ex()`
when reading CSV, but handle that in `spl_filesystem_file_read_csv()`
by treating lines with only (CR)LF as being empty as well.
Closes GH-7618.
Implements https://wiki.php.net/rfc/partially-supported-callables-expand-deprecation-notices
so that uses of "self" and "parent" in is_callable() and callable
type constraints now raise a deprecation notice, independent of the
one raised when and if the callable is actually invoked.
A new flag is added to the existing check_flags parameter of
zend_is_callable / zend_is_callable_ex, for use in internal calls
that would otherwise repeat the notice multiple times. In particular,
arguments to internal function calls are checked first based on
arginfo, and then again during ZPP, so the former suppresses the
deprecation notice.
Some existing tests which raised this deprecation have been updated
to avoid the syntax, but the existing version retained for maximum
regression coverage until it is made an error.
With thanks to Juliette Reinders Folmer for the RFC and initial
investigation.
Closes GH-8823.
smart_str uses an over-allocated string to optimize for append operations. Functions that use smart_str tend to return the over-allocated string directly. This results in unnecessary memory usage, especially for small strings.
The overhead can be up to 231 bytes for strings smaller than that, and 4095 for other strings. This can be avoided for strings smaller than `4096 - zend_string header size - 1` by reallocating the string.
This change introduces `smart_str_trim_to_size()`, and calls it in `smart_str_extract()`. Functions that use `smart_str` are updated to use `smart_str_extract()`.
Fixes GH-8896
Also refactor what happens on an empty line to return NULL instead of setting the array to [NULL] which makes no design sense at all.
However, as this is the current behaviour create a BC Shim inline function to recreate this weird HashTable in the functions which currently use this API
