* Remove native popen() and fdopen(), replacing them with subprocess calls.Guido van Rossum2007-05-241-2/+6
| | | | | Fix a path to an assert in fileio_read(). Some misc tweaks.
* Sockets facelift. APIs that could return binary data (e.g. aton() andGuido van Rossum2007-05-211-17/+37
| | | | | | | | | recv()) now return bytes, not str or str8. The socket.py code is redone; it now subclasses _socket.socket and instead of having its own _fileobject for makefile(), it uses io.SocketIO. Some stuff in io.py was moved around to make this work. (I really need to rethink my policy regarding readline() and read(-1) on raw files; and readline() on buffered files ought to use peeking(). Later.)
* Make all the multibyte codec tests pass.Guido van Rossum2007-05-171-72/+57
| | | | | | | | Changes to io.py, necessary to make this work: - Redid io.StringIO as a TextIOWrapper on top of a BytesIO instance. - Got rid of _MemoryIOMixin, folding it into BytesIO instead. - The read() functions that take -1 to mean "eveything" now also take None. - Added readline() support to BufferedIOBase. :-(
* Fix io.StringIO for wide Python builds.Walter Dörwald2007-05-161-6/+11
|
* Fix io.StringIO: String are stored encoded (using "unicode-internal" as theWalter Dörwald2007-05-161-15/+30
| | | | | | | | | encoding) which makes the buffer mutable. Strings are encoded on the way in and decoded on the way out. Use io.StringIO in test_codecs.py. Fix the base64_codec test in test_codecs.py.
* Add to an XXX comment.Guido van Rossum2007-05-091-1/+2
|
* Fix a few places where a str instead of a bytes object was used.Guido van Rossum2007-05-081-1/+1
|
* PEP 3114: rename .next() to .__next__() and add next() builtin.Georg Brandl2007-04-211-2/+2
|
* Instead of pickling the whole decoder, use the new getstate/setstate API.Guido van Rossum2007-04-171-33/+27
|
* Support name and mode attributes on all file types.Guido van Rossum2007-04-131-10/+81
| | | | | | Don't read more than one line when reading text from a tty device. Add peek() and read1() methods. Return str instead of unicode when return ASCII characters in text mode.
* Make a few more tests pass with the new I/O library.Guido van Rossum2007-04-121-2/+0
| | | | | | Fix the truncate() semantics -- it should not affect the current position. Switch wave.py/chunk.py to struct.unpack_from() to support bytes. Don't use writelines() on binary files (test_fileinput.py).
* Make sure that writing an array instance returns the number of bytes,Guido van Rossum2007-04-121-1/+6
| | | | not the number of array elements.
* TextIO improvement:Guido van Rossum2007-04-121-3/+5
| | | | | - 25% speed increse in tell(); - f.seek(0, 1) now maps to f.seek(f.tell(), 0) instead of to f.tell().
* Speed up next() by disabling snapshot updating then.Guido van Rossum2007-04-111-5/+19
|
* More efficient implementation of tell(); _read_chunk() doesn't have toGuido van Rossum2007-04-111-29/+34
| | | | call self.buffer.tell().
* Real pickling for bytes.Guido van Rossum2007-04-111-1/+5
| | | | | Restore complex pickling. Use cPickle in io.py.
* Checkpoint so I can continue to work on this at a different box.Guido van Rossum2007-04-111-25/+145
| | | | | There is somewhat working (but slow) code supporting seek/tell for text files, but extensive testing exposes a bug I can't nail down.
* truncate() returns the new size and position.Guido van Rossum2007-04-101-11/+14
| | | | | | | | write() returns the number of bytes/characters written/buffered. FileIO.close() calls self.flush(). Implement readinto() for buffered readers. Tests th check all these. Test proper behavior of __enter__/__exit__.
* Implement long positioning (Unix only, probably).Guido van Rossum2007-04-101-14/+22
| | | | Etc., etc.
* BufferedIOBase and TextIOBase should derive from IOBase, not from RawIOBase!Guido van Rossum2007-04-101-3/+2
|
* More cleanup. Renamed BlockingIO to BlockingIOError.Guido van Rossum2007-04-101-253/+312
| | | | | | Removed unused _PyFileIO class. Changed inheritance structure. TODO: do the same kinds of things to TextIO.
* Cleanup.Guido van Rossum2007-04-081-61/+124
| | | | | | | | | Add closed attribute. Support int argument to open() -- wrapping a file descriptor. For b/w compat, support readline(n). Support readlines() and readlines(n). Flush on __del__. Added some XXX comments.
* Add some backwards compatibility stuff.Guido van Rossum2007-04-071-4/+29
| | | | | This now appears to work when io.open is substituted for the real open in fileinput.py -- at least the latter's unit tests pass.
* Checkpoint.Guido van Rossum2007-04-061-16/+49
| | | | | Some cleanup of test_io.py and io.py. Added seeking to buffered reader and writer, but no tests yet.
* Get rid of duplicate definition of BufferedIOBase.Guido van Rossum2007-04-061-12/+6
|
* Added a working Text I/O layer, by Mark Russell.Guido van Rossum2007-04-061-26/+257
| | | | This is essentially a checkpoint.
* Bug 1679498: remove unused instance variables _readable, _writable andGuido van Rossum2007-03-181-4/+0
| | | | _seekable.
* Bug 1679498: unset variable 'bs'.Guido van Rossum2007-03-181-0/+2
|
* Add some XXX comments and fix BufferedReader signature.Guido van Rossum2007-03-151-2/+6
|
* Check in Daniel Stutzbach's _fileio.c and test_fileio.pyGuido van Rossum2007-03-081-1/+13
| | | | | | (see SF#1671314) with small tweaks. The io module now uses this instead of its own implementation of the FileIO class, if it can import _fileio.
* Change the specs for readinto() -- it should *not* shorten the buffer toGuido van Rossum2007-03-071-4/+10
| | | | the amount of data read.
* New version from Mike Verdone (sat in my inbox since 2/27).Guido van Rossum2007-03-071-57/+174
| | | | | | | I cleaned up whitespace but otherwise didn't change it. This will need work to reflect the tentative decision to drop nonblocking I/O support from the buffering layers.
* Mike Verdone's checkpoint, cleaned up.Guido van Rossum2007-02-271-12/+132
| | | | | | Also implemented Neal's suggestion (add fileno() to SocketIO) and some unrelated changes, e.g. remove Google copyright and make BytesIO a subclass of BufferedIOBase.
* Added some comments and docstrings. More is needed.Guido van Rossum2007-02-271-16/+62
|
* Add some XXX comments for Guido to look at.Neal Norwitz2007-02-271-0/+4
|
* Checkpoint for new I/O library.Guido van Rossum2007-02-271-0/+264
