ny significant slowdown, but incrise maintainability a lot. Note that the setting of memory_limit wasn't changes (neither in main/main.c nor in php.ini) and it
still set to 16M.
This moves unicode conversion to the filter layer
(rather than at the lower streams layer)
unicode_filter.c has been moved from ext/unicode to main/streams
as it's an integral part of the streams unicode conversion process.
There are now three ways to set encoding on a stream:
(1) By context
$ctx = stream_context_create(NULL,array('encoding'=>'latin1'));
$fp = fopen('somefile', 'r+t', false, $ctx);
(2) By stream_encoding()
$fp = fopen('somefile', 'r+');
stream_encoding($fp, 'latin1');
(3) By filter
$fp = fopen('somefile', 'r+');
stream_filter_append($fp, 'unicode.from.latin1', STREAM_FILTER_READ);
stream_filter_append($fp, 'unicode.to.latin1', STREAM_FILTER_WRITE);
Note: Methods 1 and 2 are convenience wrappers around method 3.
Add compiler version checks, as vs.net 2005 has dropped support for /YX and /GB
options, and deprecated ANSI stdio (in favour of more secure, non-standard
versions).
We avoid the problem by using poll(2).
On systems without poll(2) (older bsd-ish systems, and win32), we emulate
poll(2) using select(2) and check for valid descriptors before attempting
to access them via the descriptor sets.
If an out-of-range descriptor is detected, an E_WARNING is raised suggesting
that PHP should be recompiled with a larger FD_SETSIZE (and also with a
suggested value).
Most uses of select(2) in the source are to poll a single descriptor, so
a couple of handy wrapper functions have been added to make this easier.
A configure option --enable-fd-setsize has been added to both the unix and
win32 builds; on unix we default to 16384 and on windows we default to 256.
Windows FD_SETSIZE imposes a limit on the maximum number of descriptors that
can be select()ed at once, whereas the unix FD_SETSIZE limit is based on the
highest numbered descriptor; 256 should be plenty for PHP scripts under windows
(the default OS setting is 64).
The win32 specific parts are untested; will do that now.
Big fat note: if you're building from a .dsp, you need to replicate
the custom build step that uses MC to generate the message catalog
To make use of this fix, you need to register the event source; running "nmake
install" will handle this for you (if you also build the win32std extension
from pecl).
I'll arrange with Phil to have the installer handle this registration too.
