* [Patch #654421 from Matthew Mueller]Andrew M. Kuchling2003-02-051-2/+2
| | | | | | | | | gzip shouldn't raise ValueError on corrupt files Currently the gzip module will raise a ValueError if the file was corrupt (bad crc or bad size). I can't see how that applies to reading a corrupt file. IOError seems better, and it's what code will likely be looking for.
* Another round on SF patch 618135: gzip.py and files > 2GTim Peters2002-11-051-4/+9
| | | | | | | | | | The last round boosted "the limit" from 2GB to 4GB. This round gets rid of the 4GB limit. For files > 4GB, gzip stores just the last 32 bits of the file size, and now we play along with that too. Tested by hand (on a 6+GB file) on Win2K. Boosting from 2GB to 4GB was arguably enough "a bugfix". Going beyond that smells more like "new feature" to me.
* Related to SF patch 618135: gzip.py and files > 2G.Tim Peters2002-11-041-18/+34
| | | | | | | | | | | | | | | | Fixed the signed/unsigned confusions when dealing with files >= 2GB. 4GB is still a hard limitation of the gzip file format, though. Testing this was a bitch on Win98SE due to frequent system freezes. It didn't freeze while running gzip, it kept freezing while trying to *create* a > 2GB test file! This wasn't Python's doing. I don't know of a reasonable way to test this functionality in regrtest.py, so I'm not checking in a test case (a test case would necessarily require creating a 2GB+ file first, using gzip to zip it, using gzip to unzip it again, and then compare before-and-after; so >4GB free space would be required, and a loooong time; I did all this "by hand" once). Bugfix candidate, I guess.

* Actually, the previous batch's comment should have been different;Guido van Rossum2000-02-041-1/+2
| | | | | | | | | | *this* set of patches is Ka-Ping's final sweep: The attached patches update the standard library so that all modules have docstrings beginning with one-line summaries. A new docstring was added to formatter. The docstring for os.py was updated to mention nt, os2, ce in addition to posix, dos, mac.
* More trivial comment -> docstring transformations by Ka-Ping Yee,Guido van Rossum2000-02-041-6/+6
| | | | | | | | | | | | | | | | | | who writes: Here is batch 2, as a big collection of CVS context diffs. Along with moving comments into docstrings, i've added a couple of missing docstrings and attempted to make sure more module docstrings begin with a one-line summary. I did not add docstrings to the methods in profile.py for fear of upsetting any careful optimizations there, though i did move class documentation into class docstrings. The convention i'm using is to leave credits/version/copyright type of stuff in # comments, and move the rest of the descriptive stuff about module usage into module docstrings. Hope this is okay.
* Make read() and readlines() conform more to the file object interface:Guido van Rossum2000-02-021-3/+3

* Two different changes.Guido van Rossum1999-04-121-2/+5
| | | | | | | | | | 1. Jack Jansen reports that on the Mac, the time may be negative, and solves this by adding a write32u() function that writes an unsigned long. 2. On 64-bit platforms the CRC comparison fails; I've fixed this by casting both values to be compared to "unsigned long" i.e. modulo 0x100000000L.

* Based on a suggestion from bruce@hams.com, make a trivial change toAndrew M. Kuchling1999-03-251-32/+67
| | | | | | | | | | | | | allow using the 'a' flag as a mode for opening a GzipFile. gzip files, surprisingly enough, can be concatenated and then decompressed; the effect is to concatenate the two chunks of data. If we support it on writing, it should also be supported on reading. This *wasn't* trivial, and required rearranging the code in the reading path, particularly the _read() method. Raise IOError instead of RuntimeError in two cases, 'Not a gzipped file' and 'Unknown compression method'

* (This fix is really by Jeremy)Guido van Rossum1998-01-271-22/+29
| | | | | | | | | | | Here's my suggested replacement for gzip.py for 1.5.1. I've re-implemeted methods readline and readlines, added an _unread, and tweaked read and _read. I tried a more complicated buffer scheme for unread (using a list of strings and string.join), but it was more complicated and slower. This version is a lot faster than the current version and is still pretty simple.

* Adding Jeremy Hylton's gzip module.Guido van Rossum1997-04-301-0/+264
This requires Andrew Kuchling's zlib extension module. It still needs some doc strings.
