Is this lib production ready or deprecated?

Hi thanks for the lib! I wonder whether this lib is ready to be used in production environment, or it is already deprecated (seems nobody is maintaining it...)? Thanks!

Hi, this lib is stable under the following assumptions:

• The generator is run on a linux machine (instead of Android)
• The applier is run on Android
• Native libraries are used (this is tricky since I didn't managed to make it work using gradle so if you build it, you only get the java version which hasn't been used for quite a while).

@pspencil Thanks! Sorry I am a bit confused: What is "native libraries"? IMHO this github repo only has java code...

[pspencil]

Look inside this dir. https://www.github.com/google/archive-patcher/tree/v2/generator%2Fsrc%2Fmain%2Fjava%2Fcom%2Fgoogle%2Farchivepatcher%2Fgenerator%2Fbsdiff%2Fwrapper

It uses the native bsdiff implementation. The java version should also work. But it is just slower (and not used for a long time so not the same guarantees)

@pspencil Ha interesting! So how do I use that instead of the java one? You mentioned that I cannot use gradle to build it. Thank you!

I can no longer speak for the team on this, but the pure-java version in tag "1.0 " (https://github.com/google/archive-patcher/releases/tag/1.0) is quite stable. Depending on your use case, the performance may / may not be a problem. I'd personally (again not speaking for the team here) encourage you to try it out and see if its performance is adequate to your needs.

@andrewhayden Thank you very much! I have downloaded https://dl.bintray.com/juliantoledo/Maven/archive-patcher-1.0.jar several hours ago, and that speed (>10 seconds) is acceptable for me though a little bit slow.

@pspencil @andrewhayden By the way, a curious question: Does Google Play uses this for downloading app? If so, that sounds awesome!

[pspencil]

Yes it is one of the options.

Hello. Let me piggyback this issue because the question relates to the production-readiness of the library.

Is there a release plan for v2? I see commits being synced recently and the new generateDelta interface with ByteSource instead of File is something I could really use.
