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.
Fix targeted for oses defining those flags as enums (like Linux/glibc).
`error: converting the enum constant to a boolean [-Werror,-Wint-in-bool-context]
} else if ((!sslsock->ssl_active && value == 0 && (MSG_DONTWAIT || !sslsock->s.is_blocked)) ||`
Closes#8895.
A file that has just been opened is known to be at offset zero, and
the lseek(SEEK_CUR) system call to determine the current offset can be
skipped.
Closes#8540.
If there is a zero timeout and MSG_DONTWAIT is available (or the
socket is non-blocking), the poll() call is not necessary, and we can
just call recv() right away.
Before this change:
poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 1, 0) = 0 (Timeout)
poll([{fd=4, events=POLLIN|POLLERR|POLLHUP}], 1, 60000) = 1 ([{fd=4, revents=POLLIN}])
recvfrom(4, "HTTP/1.1 301 Moved Permanently\r\n"..., 8192, MSG_DONTWAIT, NULL, NULL) = 348
poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 1, 0) = 1 ([{fd=4, revents=POLLIN}])
recvfrom(4, "", 1, MSG_PEEK, NULL, NULL) = 0
After this change:
recvfrom(4, 0x7ffe0cc719a0, 1, MSG_PEEK|MSG_DONTWAIT, NULL, NULL) = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=4, events=POLLIN|POLLERR|POLLHUP}], 1, 60000) = 1 ([{fd=4, revents=POLLIN}])
recvfrom(4, "HTTP/1.1 301 Moved Permanently\r\n"..., 8192, MSG_DONTWAIT, NULL, NULL) = 348
recvfrom(4, "", 1, MSG_PEEK|MSG_DONTWAIT, NULL, NULL) = 0
The first poll() is replaced by recvfrom(), and the third poll() is
omitted completely.
ext/openssl/xp_ssl: eliminate poll() when MSG_DONTWAIT is available
If there is a zero timeout and MSG_DONTWAIT is available (or the
socket is non-blocking), the poll() call is not necessary, and we can
just call recv() right away.
Closes GH-8092.
* Fix regression from GH-8587
Streams hold a reference to the stream wrapper. User stream wrappers
must not be released until the streams themselves are closed.
* Add test for directories
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.
This API had rather peculiar behavior in case the provided function
is not callable. For some types of failures, it would silently
return FAILURE (e.g. a function does not exist), while for others
(e.g. a class does not exist) it would generate a warning. Depending
on what the calling code does, this can either result in silent
failure or duplicate errors.
This commit switches the contract such that zend_call_function()
always (*) succeeds, though that success might be in the form of
throwing an exception. Calling a non-callable will now consistently
throw an exception.
There are some rare callers that do want to ignore missing methods,
for legacy APIs that are specific with optional methods. For these
use cases a new zend_call_method_if_exists() API is provided.
Calling code generally does not need to explicitly check for and
report zend_call_function() failures -- it can rely on
zend_call_function() having already done so. However, existing
code that does check for failure should continue to work fine.
(*) The only exception to this is if EG(active) being false during
late engine shutdown. This is not relevant to most code, but code
running in destructors and similar may need to be aware of the
possibility.
I don't see how object can be UNDEF here -- and just passing
NULL in that case is not going to do anything reasonable either.
It would fall back to global functions with the same name.
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.

Closes GH-7356.
When flushing the stream filters actually causes data to be written to
the stream, we need to update its position, because that is not done by
the streams' write methods.
Closes GH-7354.
When mapping the file, we need to pass the proper `dwFileOffsetHigh`
instead of `0`.
