[issue6715] xz compressor support
Per Øyvind Karlsen peroyv...@mandriva.org added the comment: LZMAFile, LZMACompressor LZMADecompressor are all inspired by and written to be as similar to bz2's for easier use maintenance. I must admit that I haven't really put much thought into alternate ways to implement them beyond monkey see, monkey do.. ;) LZMAOptions is a bit awkwardly written, but it doesn't serve documentation purposes only, it also exposes these values for max, min etc. to python (ie. as used by it's regression tests) and are also used when processing various compression options passed. IMO it does serve a useful purpose, but certainly wouldn't hurt from being rewritten in some better way... -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6715 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5689] please support lzma compression as an extension and in the tarfile module
Per Øyvind Karlsen peroyv...@mandriva.org added the comment: if you're already looking at issue6715, then I don't get why you're asking.. ;) quoting from msg106433: For my code, feel free to use your own/any other license you'd like or even public domain (if the license of bz2module.c that much of it's derived from permits of course)! The reason why I picked LGPLv3 in the past was simply just because liblzma at the time was licensed under it, so I just picked the same for simplicity. I've actually already dual-licensed it under the python license in addition on the project page though, but I just forgot updating the module's metadata as well before I released 0.5.3 last month.. Martin: For LGPL (or even GPL for that matter, disregarding linking restrictions) libraries you don't have to distribute the sources of those libraries at all (they're already made available by others, so that would be quite overly redundant, uh?;). LGPL actually doesn't even care at all about the license of your software as long as you only dynamically link against it. I don't really get what the issue would be even if liblzma were still LGPL, it doesn't prohibit you from distributing a dynamically linked library along with python either if necessary (which of course would be of convenience on win32..).. tsktsk, discussions about python module for xz compression should anyways be kept at issue6715 as this one is about the tarfile module ;p -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5689 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Per Øyvind Karlsen peroyv...@mandriva.org added the comment: Yeah, I guess I anyways can just break the current API right away to make it compatible with future changes, I've already figured since long ago how it should look like.

[issue5689] please support lzma compression as an extension and in the tarfile module
Per Øyvind Karlsen peroyv...@mandriva.org added the comment: I'm the author of the pyliblzma module, and if desired, I'd be happy to help out adapting pyliblzma for inclusion with python. Most of it's code is based on bz2module.c, so it shouldn't be very far away from being good 'nuff. What I see as required is: * clean out use of C99 types etc. * clean up the LZMAOptions class (this is the biggest difference from the bz2 module, as the filter supports a wide range of various options, everything related such as parsing, api documentation etc. was placed in it's own class, I've yet to receive any feedback on this decission or find any remote equivalents out there to draw inspiration from;) * While most of the liblzma API has been implemented, support for multiple/alternate filters still remains to be implemented. When done it will also cause some breakage with the current pyliblzma API. I plan on doing these things sooner or later anyways, it's pretty much just a matter of motivation and priorities standing in the way, actual interest from others would certainly have a positive effect on this. ;) For other alternatives to the LGPL liblzma, you really don't have any, keep in mind that LZMA is merely the algorithm, while xz (and LZMA_alone, used for '.lzma', now obsolete, but still supported) are the actual format you want support for. The LZMA SDK does not provide any compatibility for this. -- nosy: +proyvind ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5689 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Per Øyvind Karlsen peroyv...@mandriva.org added the comment: ah, you're right, I forgot that the license for the library had changed as well (motivated by attempt of pleasing BSD people IIRC;), in the past the library was LGPL while only the 'xz' util was public domain.. For my code, feel free to use your own/any other license you'd like or even public domain (if the license of bz2module.c that much of it's derived from permits of course)! I guess everyone should be happy now then. :) Btw. for review, I think the code already available should be pretty much good 'nuff for an initial review. Some feedback on things not derived from bz2module.c would be nice, especially the LZMAOptions class would be nice as it's where most of the remaining work required for adding additional filters support. Would kinda blow if I did the work using an approach that would be dismissed as utterly rubbish. ;) Oh well, it's out there available for anyone already, I probably won't(/shouldn't;) have time for it in a month at least, do as you please meanwhile. :) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6715 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
