with regard to sockets. The behaviour should be aligned with PHP 4.2 now.
This has been verified to some degree.
If the underlying stream operations block when no new data is readable,
we need to take extra precautions.
If there is buffered data available, we check for a EOL. If it exists,
we pass the data immediately back to the caller. This saves a call
to the read implementation and will not block where blocking
is not necessary at all.
If the stream buffer contains more data than the caller requested,
we can also avoid that costly step and simply return that data.
second and subsequent events.
Implement very simple recursion protection for user streams written
like this:
class urlEncodeStream {
var $fp = NULL;
function stream_open($path, $mode, $options, &$opened_path)
{
$this->fp = fopen($path, $mode); // <-- this recurses infinitely
return is_resource($this->fp);
}
}
file_register_wrapper('urlencode', 'urlEncodeStream');
$fp = fopen('urlencode:///tmp/outputfile.txt', 'w');
Noticed by: Yasuo.
Eliminate similar code from network.c.
Implement fgets equivalent at the streams level, which can detect
the mac, dos and unix line endings and handle them appropriately.
The default behaviour is unix (and dos) line endings.
An ini option to control this behaviour will follow.
# Don't forget to make clean!
# I've done some testing but would appreciate feedback from
# people with scripts/extensions that seek around a lot.
uses off_t or the newer, more portable "fpos_t *".
The check could perhaps be more refined, as the test program will segfault
on older systems (like mine) that use off_t.
Filters can be stacked onto a stream; more details will follow in docs and
on php-dev.
Implement "string.rot13" filter
Allows the following script:
$fp = fopen("file.txt", "r");
stream_filter_prepend($fp, "string.rot13");
// File contents will be subject to a rot13 transformation before
// being output.
fpassthru($fp);
fclose($fp);
php_stream_set_option which can be used in a similar way as ioctl()
to set options for streams.
Current options include buffering and blocking support.
o Buffer control is support for stdio based streams.
o Blocking/non-blocking is supported for stdio and socket based streams.
and warnings (some of which are bogus) when there are problems opening
streams.
Implement sanity check on the mode used to open ftp and http connections.
This fixes Bug 12004.
Add is_url field to wrapper structure; the stream wrapper openers
will disallow opening is is_url && !PG(allow_url_fopen).
Add infrastructure for stat($url) and opendir($url).
Tidy up/centralize code that locates and instantiates wrappers for the
various operations.
Implement opendir for plain files.
Make the PHP opendir and dir functions use the streams implementations.
Add modelines for syntax highlighting the pear scripts in vim
Added notice when a requested wrapper is not found.
# This BC thing was giving me nightmares.
# It took me 10 minutes to realize I hadn't compiled in zlib support also.
in ext/standard/file.c, so a gzopen()ed file pointer can be used in
fread, fseek etc.
Improved behaviour of zlib stream.
Moved passthru code into streams.c
# I'm not happy about BG(mmap_file)
Nuked gzgetss_state as no longer needed.
natively (Thanks Marcus).
Implement php_stream_make_seekable() and add STREAM_MUST_SEEK as an
option to php_stream_open_wrapper().
See README.STREAMS for usage.
- Big indentation patch. I don't have strength to do all of the changed
- files but here's a good example. Please try and keep to the coding
- standards even if you think they suck :)
- Things to keep in mind:
- void *foo and not void * foo;
- if() { and not if()<TAB>{
- } else { and not {\nelse
-
- The streams stuff looks very cool though! :)
and rename to php_connect_nonb().
Use php_connect_nonb() instead of connect() in php_hostconnect() -> timeouts
should now work in php_hostconnect().
sock streams abstraction now uses php_sockbuf as the "abstract" pointer.
