[Question] Alternative to git-lfs under go

[Randall S. Becker]

Hi All,

Does anyone know whether it is practical to rework git-lfs under a language
other than "go"? GCC is not even close to being possible to port to my
NonStop platform (may have tried, some have died - joke -  trying). I would
like to convert this directly to C or something more widely portable. Is
there a protocol doc out there I can reference?

Thanks,
Randall

Can you say more about the context?  You might like

 git clone --filter=blob:limit=512m <repo>

which tells Git to avoid downloading any blobs larger than 512 megabytes
until you know they need them.  See Documentation/technical/partial-clone.txt
for more details.

Thanks and hope that helps,
Jonathan

Sorry, I was not clear. I am not having issues with large files or blob
limits.  Members of my community wish to use Git LFS support on their
enterprise git servers, so as platform maintainer for git on NonStop, I am
trying to accommodate them. The stumbling block is that "Go" language will
not port to the platform.

Cheers,
Randall

We have an open-source specification here [1], and the rest of our API
documentation is in here [2].

Does that help?

Thanks,

Very much, thank you!

Thanks.  Then the answer is "no": there has not been a
reimplementation of Git LFS in another language, and my advice to
someone pursuing that would be to use the native Git feature described
above instead (or to get Go working on their platform).

If I'm reading
https://github.com/git-lfs/git-lfs/blob/master/CONTRIBUTING.md
correctly, the preferred way to contact the Git LFS maintainers is
using Github's issue tracker.

Thanks and sorry I don't have better news,
Jonathan

It is the interoperability with existing Git LFS repositories that my community is requesting, not specifically any file size issues. Some want the locking function. The API looks fairly straight forward and I suspect a complete reimplementation will take less of my time than trying to get GO to actually run on the platform. Cross-compilation might be an option, but that's likely a tricky proposition that has not worked in the past - the issue there is that cross compilation requires Windows and Cygwin, which make configure rather confused and so far, not workable. Neither GCC nor GNULIB build completely in port attempts. So the answer is "NO". ☹
