Commit 5cbe5a538c disabled chunking for all writes to streams. However,
user streams have a callback where code is executed on data that is
subject to the memory limit. Therefore, when using large writes or
stream_copy_to_stream/copy the memory limit can easily be hit with large
enough data.
To solve this, we reintroduce chunking for userspace streams.
Users have control over the chunk size, which is neat because
they can improve the performance by setting the chunk size if
that turns out to be a bottleneck.
In an ideal world, we add an option so we can "ask" the stream whether
it "prefers" chunked writes, similar to how we have
php_stream_mmap_supported & friends. However, that cannot be done on
stable branches.
Closes GH-13136.
This changes memory stream to allow seeking past end which makes it the
same as seeking on files. It means the position is allowed to be higher
than the string length. The size only increases if data is appended to
the past position. The space between the previous string and position
is filled with zero bytes.
Fixes GH-9441
Closes GH-12058
This is an alternative implementation for GH-10406 that resets the
has_buffered_data flag after finishing stream read so it does not impact
other ops->read use like for example php_stream_get_line.
Closes GH-11421
This adds support for the completed event. Since the read handler could
be entered twice towards the end of the stream we remember what the eof
flag was before reading so we can emit the completed event when the flag
changes to true.
Closes GH-10505.

This change restores the old behaviour for the server socket streams
that don't support IO. This is now stored in the stream flags so it can
be later used to do some other decisions and possibly introduce some
better error reporting.
Closes GH-10877
On some filesystems, the copy operation fails if we specify a size
larger than the file size in certain circumstances and configurations.
In those cases EIO will be returned as errno and we will therefore fall
back to other methods.
copy_file_range can return early without copying all the data. This is
legal behaviour and worked properly, unless the mmap fallback was used.
The mmap fallback would read too much data into the destination,
corrupting the destination file. Furthermore, if the mmap fallback would
fail and have to fallback to the regular file copying mechanism, a
similar issue would occur because both maxlen and haveread are modified.
Furthermore, there was a mmap-resource in one of the failure paths of
the mmap fallback code.
This patch fixes these issues. This also adds regression tests using the
new copy_file_range early-return simulation added in the previous
commit.
This fix is another solution to replace d0527427be, use zend_try and zend_catch to make sure persistent stream will be released when error occurred.
Closes GH-9332.
This reverts commit d0527427be.
This patch makes Swoole/Swow can not work anymore, because Coroutine will yield to another one during socket operation, EG(record_errors) assertion will always fail, and zend_begin_record_errors() was only used during compile time before.
Note: zend_emit_recorded_errors() and the typo fix are reserved.
This is not actually related to SSL handshake but stream socket creation
which does not clean errors if the error handler is set. This fix
prevents emitting errors until the stream is freed.
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.
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.
