R. David Murray 25b4add5b0 Fix issue 2245. aifc now skips any chunk type it doesn't actually
process instead of throwing errors for anything not in an explicit
skip list.  This is per this spec: http://www.cnpbagwell.com/aiff-c.txt.
Spec reference and test sound file provided by Santiago Peresón, fix
based on patch by Hiroaki Kawai.

Skip Montanaro e99d5ea25b added __all__ lists to a number of Python modules
added test script and expected output file as well
this closes patch 103297.
__all__ attributes will be added to other modules without first submitting
a patch, just adding the necessary line to the test script to verify
more-or-less correct implementation.

Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Guido van Rossum 2663c13c5b Sjoerd Mullender:
The (relatively) new chunk module uses seek, not setpos.  One instance
of the call still needed to be fixed.
2000-03-07 15:19:31 +00:00
Guido van Rossum 4acc25bd39 Mass patch by Ka-Ping Yee:
1. Comments at the beginning of the module, before
       functions, and before classes have been turned
       into docstrings.

    2. Tabs are normalized to four spaces.

Also, removed the "remove" function from dircmp.py, which reimplements
list.remove() (it must have been very old).

"""
Extended chunk so that it can also handle formats that are almost
according to EA IFF 85.  In particular, added options to handle
little-endian and to handle formats that include the header size in
the chunk size value.

Fixed a bug where the header size was included in the chunk size, which
it isn't according to EA IFF 85.

Added a new method getsize() to get the size of the chunk (excluding
header).

Fixed chunk documentation (TIFF doesn't look like it uses chunks).
Converted wave to use chunk.  Wave uses EA IFF 85 chunks except that
it uses little-endian encoding of integer data.

Removed __del__ methods from aifc and wave since I got an
AttributeError there upon exit.

Fred Drake 4316135a44 Make the mode parameter to open() default in the same way as for wave.open(). 1999-06-22 21:23:23 +00:00
Guido van Rossum 8ea7bb8e78 Patch/new code by Sjoerd Mullender:
Separate the Chunk class out of the aifc module into a new "chunk" module.

Guido van Rossum 5c071fab8f The _comp_data() function never worked, it contained a reference to
undefined 'nframes'.  Should be self._nframes.  (Andrew Dalke & kjpylint)

Guido van Rossum 2c2f731daf [Sjoerd Mullender]
Don't use CL module since all constants are now in cl.
1998-08-07 15:28:23 +00:00
Guido van Rossum bb189dbcb0 Small corrections to comments that were cloned from aifc; moreover
the description of setparams() was wrong.

wave.py: Include the tag of an unknown format in the exception.

Guido van Rossum afe3ebfa5c Use newer struct, which handles unsigned long right 1997-01-11 19:21:09 +00:00
Guido van Rossum 36bb181cdf Rewrote _{read,write}_{short,long} to use the newly revamped struct
module.  (Small problem: struct.pack() won't deal with the Python long
ints returned by struct.unpack() for the 'L' format.  Worked around
that for now.)

just set file pointer correctly instead of returning the complete
file.
