The php_stream_read() and php_stream_write() functions now return
an ssize_t value, with negative results indicating failure. Functions
like fread() and fwrite() will return false in that case.
As a special case, EWOULDBLOCK and EAGAIN on non-blocking streams
should not be regarded as error conditions, and be reported as
successful zero-length reads/writes instead. The handling of EINTR
remains unclear and is internally inconsistent (e.g. some code-paths
will automatically retry on EINTR, while some won't).
I'm landing this now to make sure the stream wrapper ops API changes
make it into 7.4 -- however, if the user-facing changes turn out to
be problematic we have the option of clamping negative returns to
zero in php_stream_read() and php_stream_write() to restore the
old behavior in a relatively non-intrusive manner.
Although TsHashTable and the according API are supposed to easily make
a HashTable thread-safe, they do not; for instance, there can be race
conditions between finding and updating entries. We therefore avoid
the usage of TsHashTable in favor of a HashTable with our own mutex
management.
The patch has been provided by krakjoe@php.net; I only did some minor
fixes and tweaks.
Now that set() is gone, there is little point in keeping get(), as
it is essentially just a different way of writing cast_object()
now.
Closes GH-4202.
The AC_CHECK_TYPE was refactored in more recent versions of Autoconf
and the call with two arguments is obsolete and not recommended anymore.
This patch also refactors some leftovers of using ulong and uint which
are not standard nor common usages of types in C.
The ulong can be used as zend_ulong and uint usage is actually
`unsigned int`.
The usage of HAVE_ULONG removed since it is not used in current code
base.
Legacy edgecase for some legacy HPUX systems removed:
- sys/stream.h header is not checked and the HAVE_SYS_STREAM_H is
not defined with current build system.
- flags are unsigned int
- max_allowed_packet changed to unsigned int
We apply only the most minimal fix here, and will cater to the
unnecessary re-allocation for PHP-7.4.
We don't need to add a regression test, since bug39606.phpt and
bug77621.phpt already show the misbehavior.
As of PHP 7.3.0, case-insensitive constants are deprecated. We catch
up on this with regard to ext/com_dotnet, which allows to import
constants from typelibs, by triggering a deprecation notice whenever
`com_load_typelib()` is called with `$case_sensitive` being `false`,
and whenever `com.autoregister_casesensitive` is set to `false`,
regardless of whether there are actually constants in the typelib which
would be imported.
We must not check uninitialized values (i.e. `c.value`), and we have to
use proper types for printf-style formats (i.e. `char *` instead of
`zend_string *`).
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.
