"XZ for Java" http://tukaani.org/xz/java.html which we already use for XZ compression likely knows how to do LZMA, I haven't explicitly looked into it, though. > Add 7zip or RAR archive support > --- > > Key: COMPRESS-54 > URL: https://issues.apache.org/jira/browse/COMPRESS-54 > Project: Commons Compress > Issue Type: New Feature > Components: Archivers > Environment: N/A >Reporter: Tim Pinet >Priority: Minor > Original Estimate: 30h > Remaining Estimate: 30h > > Has anyone looked into adding support for 7zip and RAR file types?

It really looks like C-style Java code, which is pretty hard to integrate into a Java project. 1. As some time has passed meanwhile, has anyone managed to convert it into a stream based Java implementation? Or even tried to embedd it into Apache Commons Compress? 2. Does anyone know if licenses could be a conflicting issue? > Add 7zip or RAR archive support > --- > > Key: COMPRESS-54 > URL: https://issues.apache.org/jira/browse/COMPRESS-54 > Project: Commons Compress > Issue Type: New Feature > Components: Archivers > Environment: N/A >Reporter: Tim Pinet >Priority: Minor > Original Estimate: 30h > Remaining Estimate: 30h > > Has anyone looked into adding support for 7zip and RAR file types?

I think there have been some questions as to whether this is allowed; AFAIK it's not covered in the existing rules. Also, the Wikipedia page says that the LZMA compression is similar to deflate, so maybe that will help understand the code. > Add 7zip or RAR archive support > --- > > Key: COMPRESS-54 > URL: https://issues.apache.org/jira/browse/COMPRESS-54 > Project: Commons Compress > Issue Type: New Feature > Environment: N/A >Reporter: Tim Pinet >Priority: Minor > Original Estimate: 30h > Remaining Estimate: 30h > > Has anyone looked into adding support for 7zip and RAR file types?

Input and Output mechanisms are mixed together. Codestyle doesn't follow Sun standards (looks like C), access modifiers are all public or package scoped, even for private members. Lots of "global variables". All the work is done with bitshifting which makes everything hard to read. However, with some manpower it should be possible to refactor everything into streams. > Add 7zip or RAR archive support > --- > > Key: COMPRESS-54 > URL: https://issues.apache.org/jira/browse/COMPRESS-54 > Project: Commons Compress > Issue Type: New Feature > Environment: N/A >Reporter: Tim Pinet >Priority: Minor > Original Estimate: 30h > Remaining Estimate: 30h > > Has anyone looked into adding support for 7zip and RAR file types?

For RAR I found sources for o rarlib (GPL) o unrar (sort of free but cpp) For 7zip I found o p7zip (LGPL + restriction, written in C) o j7zip (LGPL) And there are other algorithms (and libraries) to implement as well: ARJ, CAB, ... But I fear some of those implementations need to be hosted somewhere else (due to the licensing). I'd suggest to create a github project for it. > Add 7zip or RAR archive support > --- > > Key: COMPRESS-54 > URL: https://issues.apache.org/jira/browse/COMPRESS-54 > Project: Commons Compress > Issue Type: New Feature > Environment: N/A >Reporter: Tim Pinet >Priority: Minor > Original Estimate: 30h > Remaining Estimate: 30h > > Has anyone looked into adding support for 7zip and RAR file types?
