[llvm-dev] 'git llvm push' not working for me on Windows

Wed Nov 28 12:55:19 PST 2018

Poking around in the .git\llvm-upstream-svn tree, I find that llvm\trunk\test\DebugInfo\Generic is empty, as are all the other subdirectories of test\DebugInfo that I tried.  I have other files in the checkin that are in leaf directories but those files all exist.
I hacked git-llvm to add a –verbose option:

`git apply --verbose -p2 -` returned 1

Patch doesn't apply: maybe you should try `git pull -r` first?

And now it's failing for me also… complaining about "no such file or directory" on a file that plainly exists.
Verbose log attached.

OK, I've managed to do it:

I was trying to push it from a build/ directory, maybe that's why the git apply was failing.

Pushing the commit from the root of the repo worked.

Hi,

The patch only changes one file in clang. Here's the patch: https://reviews.llvm.org/D54974

Attached the log. It seems to complain about the git apply -p2.

Maybe it's something related to arc?

Can you please run "git llvm --verbose push" and send me the output?

BTW, I've just committed a fix for the handling of binary patch data when you're running it under python3.X. I don't believe that was a regression from my recent changes, but if you're using python3, you could see if that fixes it for you.

I'm facing this now on Linux.

Any idea how to fix it?

I've verified that none of the files I tried to check in had Windows-style line endings. It's something else.

As a test case, try committing a change to clang/test/SemaCXX/sourceranges.cpp?

I believe most editors force Windows-style line endings for that file (they show up in my vim as “^M”). I recently tried to commit a change to that file using “git llvm push” on macOS, but hit what I think is the same issue. At least, the error message was the same.

FTR the commit where it failed for me had both llvm and clang changes.  I wonder if that contributed.

Hm.  Just now it worked for me for r347271.  If it happens again I'll try verbose mode and attach a log.
Thanks,

Usually every time I've seen that error message, it's been related to line ending normalization.  But James is right, I did use it successfully this morning as well as yesterday.

It does sound like I must've broken something, but I believe zturner used it on windows successfully. Perhaps you could help me debug the issue? Possibly running it with --verbose would show something useful.

My usual response to a problem from git-llvm (which is most often
an anti-virus issue) is to blow away .git\llvm-upstream-svn but
that doesn't help this time.

I see James Knight did a "performance improvement" on Friday,
perhaps that doesn't work so well on Windows?  The main
performance cost is one-time, and as long as my anti-virus isn't
trashing things behind my back the performance is just fine;
so it's not clear this is really a necessary improvement.
If it's interfering with developing the new git repo, then I'd
suggest making it optional or platform-dependent.

As a workaround I fetched the previous version of git-llvm
and put it earlier in my PATH, that worked.
