[issue20781] BZ2File doesn't decompress some .bz2 files correctly
James Dominy added the comment: Ah, I did some digging. It turns out pbzip2 is installed on the system in question, and more annoyingly, /usr/bin/bzip2 is a symlink to pbzip2. I didn't realise the file was compressed by pbzip2.

[issue20781] BZ2File doesn't decompress some .bz2 files correctly
James Dominy added the comment: How does one create a multi-stream bzip2 file in the first place? And how do I tell it's multi-stream. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20781 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue20781] BZ2File does decompress some .bz2 files correctly
New submission from James Dominy: bz2.BZ2File does not decompress a file (see attached) correctly. This file can be decompressed and compressed via stadard unix tools (bzip2 and bunzip2) without change. Consider ... $ python Python 2.7.6 (default, Dec 7 2013, 22:49:16) [GCC 4.8.2] on linux2 Type help, copyright, credits or license for more information. import bz2 import hashlib len(bz2.BZ2File(example-file.csv.bz2, r, 0).read()) 90 hashlib.md5(bz2.BZ2File(example-file.csv.bz2, r, 0).read()).hexdigest() 'e2d4ce212a040c879cb256f88c9faab9' len(bz2.BZ2File(example-file.csv.bz2, rb, 0).read()) 90 hashlib.md5(bz2.BZ2File(example-file.csv.bz2, rb, 0).read()).hexdigest() 'e2d4ce212a040c879cb256f88c9faab9' It looks like bz2 is not dealing with the second block. This is not the first file I've come across that has this problem, and initially I thought it was the file not the module. I've attached a copy of the file. I use gentoo on a 64bit intel core i5. -- components: IO files: example-file.csv.bz2 messages: 212250 nosy: James.Dominy priority: normal severity: normal status: open title: BZ2File does decompress some .bz2 files correctly versions: Python 2.7 Added file: http://bugs.python.org/file34230/example-file.csv.bz2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20781 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1503502] Pdb doesn't call flush on its stdout file descriptor
James Dominy [EMAIL PROTECTED] added the comment: I've been working on a patch that allows pdb when run as a script to split it's output such that the program being debugged uses a specified tty for stdin/stdout, and leave the pdb.py IO on the original stdin/stdout. I think perhaps these efforts should be merged. Certainly your suggested patch would make my work much easier. -- nosy: +sirlark ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue1503502 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
