Git get stucked on fifo::Inode::ReadDataFromBuffer

Reported by: emitrax Owned by: nobody

I was trying to check out Webkit source from Haiku running in vmware directly on a USB stick BFS formatted.

Git got stuck and I've not idea why. The stack trace is attached.

Since the program is waiting on a fifo file, don't know what is used for, how should I found out who is the writer on the other side?

I could not find any fifo related KDL command.

That probably just means that no data arrived. It's just the question why, but this could have any reason. Switching to a more likely component.

Is this problem reproducible?

I tried it only once at work. I'll see if I can try it again tomorrow.

Any suggestion or other info I should gather that might be useful?

This might not even be a kernel problem at all.

Replying to emitrax:

I would expect the fifo to be a pipe to a child process (maybe a transport tunnel like ssh), so the problem is probably just that the writer doesn't write anything for any reason. Finding out who is the writer and why it isn't doing anything would get us further. A look at the git sources to understand what is supposed to happen at this point might also help.

Ok, I tried again this morning from work and the directory got deleted. CPU activity was bit higher, 35% at most, but was going up and down. Personally I would expect something a lot higher to get thing faster. Looks like my slow laptop (1.6Ghz) brings out a lot of issues.

Now I'm trying to check out again the source.

PS. I just noticed "block notifer/writer" KDL'ed. I'll open a different bug. PSS. Would it be possible to write some KDL command to get more info about the pipe ?

Have you run into this issue recently? Perhaps try it on R1Alpha4.1 on that same hardware if you still have it and see if this still happens. There's been a few revisions to haiku and to git since this first happened.
