In other words, don't automatically unserialize when the magic
phar:// stream wrappers are used.
RFC: https://wiki.php.net/rfc/phar_stop_autoloading_metadata
Also, change the signature from `getMetadata()`
to `getMetadata(array $unserialize_options = [])`.
Start throwing earlier if setMetadata() is called and serialization threw.
See https://externals.io/message/110856 and
https://bugs.php.net/bug.php?id=76774
This was refactored to add a phar_metadata_tracker for the following reasons:
- The way to properly copy a zval was previously implicit and undocumented
(e.g. is it a pointer to a raw string or an actual value)
- Avoid unnecessary serialization and unserialization in the most common case
- If a metadata value is serialized once while saving a new/modified phar file,
this allows reusing the same serialized string.
- Have as few ways to copy/clone/lazily parse metadata (etc.) as possible,
so that code changes can be limited to only a few places in the future.
- Performance is hopefully not a concern - copying a string should be faster
than unserializing a value, and metadata should be rare in most cases.
Remove unnecessary skip in a test(Compression's unused)
Add additional assertions about usage of persistent phars
Improve robustness of `Phar*->setMetadata()`
- Add sanity checks for edge cases freeing metadata, when destructors
or serializers modify the phar recursively.
- Typical use cases of php have phar.readonly=1 and would not be affected.
Closes GH-5855
The hash extension is always available since PHP-7.4. The symbol
HAVE_HASH_EXT is kept for BC reasons and removed in PHP-8.0.
This patch also removes the PHAR_HASH_OK since it is no longer
relevant.
This patch follows previous license year ranges updates. With new
approach source code files now have simplified headers with license
information without year ranges.
This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.
A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.
This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.
With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.
Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.
The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
Preventing integer overflows in principle, which allows to avoid additional
range checks. The phar format is based on 32-bit lengths, so the storage
sizes was kept same.

So we can use it there as well...
For now I've retained the zend_smart_str_public.h header, though
it would probably be better to just move that one struct into
zend_types.h.
