Blocking waiting for file lock on the git database

[Yoric]

Since my rust upgrade to nightly-2016-04-10, I cannot use cargo at all in one of my git repos. Well, cargo clean works, but not cargo update, cargo build, cargo test, etc.

I imagine that I need to remove a file, but I have no clue which one :/

[Yoric]

Note: Cleaning up my \rm -Rf ~/.multirust/toolchains/nightly-2016-04-10/cargo/ seems to have solved the issue, but I would prefer something more discoverable.

Thanks for the report! Could you gist the output of Cargo as well? Also, is the repo public so I could repro it as well?

[Yoric]

This happened again today.

The only output of Cargo is

$ cargo build
    Blocking waiting for file lock on the git database

I got this by building Yoric/foxbox@822a52e using nightly-2016-04-29. After cleaning up the cargo directory of my toolchain, I couldn't reproduce.

I think I had hit ^C during a build previously, which might explain the issue.

[alexcrichton]

Hm in theory interrupting doesn't affect a build as the file locks are associated with the process, not state on the filesystem. I unfortunately couldn't reproduce either :(

I have the same issue on windows. What can I do?

[alexcrichton]

@stiv-yakovenko do you have a way to reproduce this issue? I could help debug if that comes up

[stiv-yakovenko]

Alex, this was caused by another cargo.exe running in background. That cargo.exe was probably launched by intellijIDEA. What if we give more info in this message?

[alexcrichton]

Oh in that case there's not really a bug there per se, it's working as intended?

[stiv-yakovenko]

Yes, it is.

[Yoric]

Note that in the case that prompted me to open this bug, after waiting 1h (for something that typically builds in 20secs), I still could not use cargo. So, at least in that case, it is a bug.

[alexcrichton]

@Yoric do you know what filesystem/OS you're using?

[Yoric]

hfs volume on MacOS X 10.11.5

[Yoric]

Note that I haven't checked at the time whether a rustc process could have been hung/zombified.

[alexcrichton]

Hm ok, this can't be reproduced though?

[Yoric]

Well, as usual, once I remove the directory, I cannot reproduce.
