buffers.
When selecting for read, the streams are examined; if any of them have
pending read data, no actual select(2) call is performed; instead the
streams with buffered data are returned; just like a regular select
call.
Prevent erroneous warning in stream_select when obtaining the fd.
- webdav-specific stuff removed (should be handled using httpd.conf
LIMIT or equivalents)
- always_populate_raw_post_data now working on any method, not just
POST (and webdav methods with allow_webdav_methods), when
Content-Length is greater zero
- raw input data is also available using php://input stream,
this way one doesn't have to care about memory_limit
- input data is now always consumed (although maybe ignored,
this fixes we had withproblems with keep-alive connections
@ raw POST data is now available as php://input stream (hartmut)
php_stream_gets is now a macro which calls php_stream_get_line. The latter
has an option argument to return the number of bytes in the line.
Functions like fgetcsv(), fgetss() can be made binary safe by calling
php_stream_get_line directly.
# HEADS UP: You will need to make clean after updating your CVS, as the

When not enough data to satisfy a read was found in the buffer, fgets modifies
the buf pointer to point to the position to store the next chunk. It then
returned the modified buf pointer, instead of a pointer to the start of the
buffer.
Also added some infrastructure for making fgets grow the buffer on-demand to
the correct line-size. Since streams uses reasonable chunk sizes, the
performance of the realloc's should be pretty good; in the best case, the line
is already found completely in the buffer, so the returned buffer will be
allocated to precisely the correct size.
In the worst case, where the buffer only contains part of the line, we get a
realloc per buffer fill. The reallocs are either the size of the remainder
of the line, or the chunk_size (if the buffer sill does not contain a complete
line). Each realloc adds an extra byte for a NUL terminator.
I think this will perform quite well using the default chunk size of 8K.
data is sent to the kernel using write(2). fsync'ing a
file descriptor is not required -- writing to a fd has the same
affect as calling fflush after each fwrite.
