Local user streams must not be able to open(), URLs if allow_url_include is off
Implemented new function stream_is_local()
[
- stream_wrapper_register() extended with additional optional argument "flags"
of type long. This time only one flag is implemented
- STREAM_IS_URL, that means that userstream wrapper is remote (URL).
By default stream is local.
- stream_is_local() is a new function that accepts stream and tell if this
stream is local or remote (URL)
]
Allow for non-blocking negotiation when calling stream_socket_enable_crypto().
That function will return the foolowing values:
false - negotiation failed
0 - try again when more data is available (only for non-blocking sockets)
true - ssl was enabled
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.
Register filters as resources when
instantiated by stream_filter_(ap|pre)pend().
Export php_stream_filter_flush() internal function to wind buffered data
out of a particular filter until consumed by a later filter or sent to
stream->readbuffer or stream->ops->write()
You may then set options that affect streams operations for the whole script.
Added stream_socket_enable_crypto() which allows you to turn on or off a crypto
layer (eg: SSL/TLS) on stream, if supported by the underlying transport.
Registered a bunch of constants for that.
