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 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.
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.
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()
Disables a wrapper (user-defined or built-in) for the life of the request.
Add stream_wrapper_restore()
Restores the wrapper originally defined at the time the request started
to the protocol name mentioned.
Userdefined wrappers were being registered into a global wrapper hash
which can cross threads. Termination of once instance then has the
potential to leave an active stream in another instance with no wrapper
leading to segfault.
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.
Usage:
php_stream *stream = php_stream_fopen("/path/to/file", "r+b", NULL,
STREAM_OPEN_PERSISTENT | ENFORCE_SAFE_MODE | REPORT_ERRORS);
the filename and mode are combined to form the hash key for the persistent
list; they must be identical for this same stream to be returned again in the
next request.
Calling php_stream_close() on a persistent stream *will* close it, as is
usual with all persistent resources in PHP/ZE.
This is deliberately *not* exposed to user-space PHP at this time.
Main Changes:
- Implement a socket transport layer for use by all code that needs to open
some kind of "special" socket for network or IPC.
- Extensions can register (and override) transports.
- Implement ftruncate() on streams via the ioctl-alike option interface.
- Implement mmap() on streams via the ioctl-alike option interface.
- Implement generic crypto API via the ioctl-alike option interface.
(currently only supports OpenSSL, but could support other SSL toolkits,
and other crypto transport protocols).
Impact:
- tcp sockets can be overloaded by the openssl capable sockets at runtime,
removing the link-time requirement for ssl:// and https:// sockets and
streams.
- checking stream types using PHP_STREAM_IS_SOCKET is deprecated, since
there are now a range of possible socket-type streams.
Working towards:
- socket servers using the new transport layer
- mmap support under win32
- Cleaner code.
# I will be updating the win32 build to add the new files shortly
# after this commit.
This breaks user-space filters (for the time being), and those
weird convert.* filters in ext/standard/filters.c
The filters stack has been separated into one chain for read and one chain
for write.
The user-space stream_filter_append() type functions currently only operate
on the read chain. They need extending to work with the write chain too.
