refresh to latest libgit2?

[esjmb]

Hi, thanks for great software. i wonder could this repository be refreshed to the latest gitlib2? thanks.

[jwiegley]

You mean the latest libgit2? It's on the task list, but that's not a minor undertaking, there is no one funding gitlib development, and the current version is working for all my use cases. So it may be a while before this happens.

[esjmb]

:) yes,, libgit2.

no problem. I might have a bash myself if you don't mind and ping you for help if i hit walls. I'd like to gain access to blame support.

for starters, looks to me that the generation of about 8 Bindings/xx.hs generations fail with the current c2hsc, and thus need manual writing. The present hlibgit2 versions serve reasonably well as a base for some with minor mods, but some need writing from scratch. That about right? Any other big hurdles I'm not seeing?

[jwiegley]

That's about right. c2hsc can only do about 90% of the job, and the rest is manual based on your understanding of the header files. That's mainly why it hasn't happened yet.

Hi John,

I've completed a refresh for the latest libgit2 on a local clone. It's compiling, building and with 'build test' results below. I wouldn't presume to issue a pull request etc. until I've tested locally in anger (appreciate that gen tests are necessarily minimal) but if you want the update or a link to a temporary fork, let me know, and i'll provide one - you may be in a better position to test more quickly against your other projects...

thanks,
Stephen.

Distributions like Debian probably want to avoid an embedded code copy of libgit2 inside hlibgit2. So, getting it updated to a version that is available in Debian (such as 0.23) is quite likely a blocker for getting gitlib-libgit2 into Debian.

[jwiegley]

@esjmb Is your upgrade ready for inclusion?

[jwiegley]

Also, I'd like to avoid an embedded copy @joeyh, but this creates pain for everyone not using a system like Debian. It's easiest for Haskell users if Hackage provides everything you need.

[jwiegley]

However, maybe we should have an option to allow the use of an external libgit2.

[joeyh]

An option to use the system libgit2 would be a good balance.
This approach is also taken by persistent-sqlite.

libgit2 is up to 0.25.1 now.
