This issue happens because http wrapper sets peer_name but then does not
remove so it stays in the context. The fix removes the peer name from
the context after enabling crypto.
In addition to bug #74796, this also fixes bug #76196.
In addition it should be a final fix for those SOAP bugs:
bug #69783
bug #52913
bug #61463
Triggers the assertion as with SEEK_CUR the stream position is set to a
negative value so we force the failure without affecting its position
instead.

We need to avoid signed integer overflows which are undefined behavior.
We catch that, and set `offset` to `ZEND_LONG_MAX` (which is also the
largest value of `zend_off_t` on all platforms). Of course, that seek
may fail, but even if it succeeds, the stream is no longer readable,
but that matches the current behavior for offsets near `ZEND_LONG_MAX`.
Closes GH-15989.

This was first reported as a leak in GH-15026, but was mistakingly
believed to be a false positive. Then an assertion was added and it got
triggered in GH-15908. This fixes the leak. Upon merging into master the
assertion should be removed as well.
Closes GH-15924.
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 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.
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.
copy_file_range() is a Linux-specific system call which allows
efficient copying between two file descriptors, eliminating the need
to transfer data from the kernel to userspace and back. For
networking file systems like NFS and Ceph, it even eliminates copying
data to the client, and local filesystems like Btrfs and XFS can
create shared extents.
Since we're going to read from the current stream position anyway, the
`max_len` should be the size of the file minus the current position
(still catering to potentially filtered streams). We must, however,
make sure to cater to the file position being beyond the actual file
size.
While we're at, we also fix the step size in the comment, which is 8K.
A further optimization could be done for unfiltered streams, thus
saving that step size, but 8K might not be worth it.
Closes GH-7693.
On x86_64 glibc memrchr() uses SSE/AVX CPU extensions and works much
faster then naive loop. On x86 32-bit we still use inlined version.
memrchr() is a GNU extension. Its prototype becomes available when
<string.h> is included with defined _GNU_SOURCE macro. Previously, we
defined it in "php_config.h", but some sources may include <string.h>
befire it. To avod mess we also pass -D_GNU_SOURCE to C compiler.
Use ASCII case conversion instead of locale-dependent case conversion in
the following places:
* grapheme_stripos() and grapheme_strripos() in the "fast" path
* ldap_get_entries()
* oci_pconnect() for case folding of parameters when constructing a key
into the connection or session pool
* SoapClient: case folding of function names
* get_meta_tags(): case conversion of property names
* http stream wrapper: header names
* phpinfo(): anchor names
* php_verror(): docref URLs
* rfc1867.c: Content-Type boundary parameter name
* streams.c: stream protocol names
Using locale-dependent case folding for these cases is either
unnecessary or actively incorrect. These functions could have
misbehaved when used with certain locales (e.g. Turkish).
Closes GH-7511.
The stream position is not related to the buffer, and needs to be
updated for non-seekable streams as well. The erroneous condition
around the position update is a relict of an old commit[1].
The unexpected test expectation is due to bug #81345.

1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.
4. fixed indentation in some files before |
