d76e7796c9 Instead of pickling the whole decoder, use the new getstate/setstate API. 2007-04-17 02:38:04 +00:00

13633bb8c5 Support name and mode attributes on all file types. 
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.

dc0b1a1069 Make a few more tests pass with the new I/O library. 
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).

d410395ea7 Make sure that writing an array instance returns the number of bytes, 
not the number of array elements.

aa43ed95cd TextIO improvement: 
- 25% speed increse in tell();
- f.seek(0, 1) now maps to f.seek(f.tell(), 0) instead of to f.tell().

b9c4c3e455 Speed up next() by disabling snapshot updating then. 2007-04-11 16:07:50 +00:00

cba608cadb More efficient implementation of tell(); _read_chunk() doesn't have to 
call self.buffer.tell().

0dd32e246c Real pickling for bytes. 
Restore complex pickling.
Use cPickle in io.py.

9b76da6a8f Checkpoint so I can continue to work on this at a different box. 
There is somewhat working (but slow) code supporting seek/tell for text files,
but extensive testing exposes a bug I can't nail down.

8742977b33 truncate() returns the new size and position. 
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__.

53807dabf0 Implement long positioning (Unix only, probably). 
Etc., etc.

cce92b27d6 BufferedIOBase and TextIOBase should derive from IOBase, not from RawIOBase! 2007-04-10 14:41:39 +00:00

141f767d46 More cleanup. Renamed BlockingIO to BlockingIOError. 
Removed unused _PyFileIO class.
Changed inheritance structure.
TODO: do the same kinds of things to TextIO.

4f0db6e4a1 Cleanup. 
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.

9be5597abf Add some backwards compatibility stuff. 
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.

76c5d4d72d Checkpoint. 
Some cleanup of test_io.py and io.py.
Added seeking to buffered reader and writer, but no tests yet.

78892e4613 Added a working Text I/O layer, by Mark Russell. 
This is essentially a checkpoint.

a9e2024b84 Check in Daniel Stutzbach's _fileio.c and test_fileio.py 
(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.

00efeadbcf Change the specs for readinto() -- it should *not* shorten the buffer to 
the amount of data read.

01a2752d19 New version from Mike Verdone (sat in my inbox since 2/27). 
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.

68bbcd2a71 Mike Verdone's checkpoint, cleaned up. 
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.
