conversions of filename entries.
Normal path conversions will simply use this converter,
Certain other protocols (such as http) which specify a
required character set (utf8), may override the conversion
by defining a path_encode() and/or path_decode() wrapper ops method.
update userspace function file_get_contents().
Note: fgc()'s second parameter (use_include_path) has been changed
to be a bitmask "flags" parameter instead.
For the most commonly used values (TRUE, 1) this will continue functioning
as expected since the value of FILE_USE_INCLUDE_PATH is (coincidentally) 1.
The impact to other values should be noted in the migration6 guide.
This change makes it possible to allow fgc() to return binary file
contents (default) or unicode transcoded contents (using FILE_TEXT flag).
This updates userspace functions fpassthru() and readfile()
UG(output_encoding) is used by php_stream_passthru() to translate
unicode stream contents back to an outputable character set.

to be a bitmask "flags" parameter instead.

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.
fgets() will work now as will anything which calls one of the
_php_stream_get_line() family of functions.
The one exception here is when the legacy defines are used on a unicode
stream. At the moment they'll simply return NULL, I'll update these
to do sloppy conversion in a bit.
'make (u)test' still doesn't work, but it's a different doesn't work.
<?php
declare(encoding="latin1");
$a = "1234å67890";
file_put_contents( "/tmp/testuc.1", $a);
file_put_contents( "/tmp/testuc.2", (string) $a);
$context = stream_context_create();
stream_context_set_params($context, array( "output_encoding" => "latin1" ) );
file_put_contents( "/tmp/testuc.3", $a, FILE_TEXT, $context);
file_put_contents( "/tmp/testuc.4", (string) $a, FILE_TEXT, $context);
?>
But it still throws a warning on ".3". It's a small design issue that I
didn't want to touch right now.
Don't be frightened by the size of this commit.
A significant portion of it is restoring the read buffer semantics back
to what PHP4/5 use. (Or a close aproximation thereof).
See main/streams/streams.c and ext/standard/file.c for a set of
UTODO comments covering work yet to be done.
Now IS_BINRAY data type is removed and IS_STRING starts behave as IS_BINARY in unicode mode. IS_STRING is incompatible with IS_UNICODE, so ALL functions should be improved to support unicode mode.
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.
used to return "" and not bool(false). It's not worth keeping it because
STR_FREE() and zval_dtor() always have to check for it and it slows down
the general case. In addition, it seems that empty_string has been abused
quite a lot, and was used not only for setting zval's but generally in
PHP code instead of "", which wasn't the intention. Last but not least,
nuking empty_string should improve stability as I doubt every place
correctly checked if they are not mistakenly erealloc()'ing it or
calling efree() on it.
NOTE: Some code is probably broken. Each extension maintainer should
check and see that my changes are OK. Also, I haven't had time to touch
PECL yet. Will try and do it tomorrow.
behavior/API is as follows:
1) To close a persistent use php_stream_pclose(), it will close the stream
and remove it from the persistent list.
2) Inside PHP code only explicit fclose() will close persistent streams,
all other actions such as unset() or assigning a value to stream handle
will not.
3) Regular streams can still be closed by either fclose(), unset() or an
assignment of a value to the stream handler.
Make contexts auto-registered, ensures userland contexts
and C API contexts are both dealt with on request shutdown.
Also brings contexts in keeping with streams which are already
auto-registered.
