Created attachment 756042 [details]
Log with LIBGUESTFS_TRACE=1 LIBGUESTFS_DEBUG=1
This is a log when running upload-test.pl with both trace and
debug enabled.
Also I am running:
kernel-3.9.4-200.fc18.x86_64
libvirt-daemon-1.0.5.1-1.fc20.x86_64
qemu-1.5.0-1.fc18.x86_64 [self-compiled from Rawhide]
Also happens with upstream qemu from git (fixed because there's currently an unrelated bug in qemu). Also happens with qemu 1.5.0-4 [self-compiled from Rawhide] Does not happen with $g->upload is replaced by $g->write, indicating this is probably a protocol synchronization error related to FileIn & error handling. Fixed upstream in commit 697b0f89fed04a4017e033861a9eaaa40b3270d9. |
Created attachment 756038 [details] upload-test.pl Description of problem: See attached test script. This test script creates a directory and then uploads a file to this directory (to the directory itself, not inside the directory). Obviously this should fail since you can't upload to a directory. And usually it does fail. However once in a while (very rarely) it hangs. Version-Release number of selected component (if applicable): libguestfs 1.23.1 How reproducible: 100% reproducible using the test script, although the actual failure is very rare. Steps to Reproduce: 1. Run attached test script. 2. Observe that after a while the spinner will hang. 3. Rerun with LIBGUESTFS_DEBUG=1 to get more detail. Actual results: Hangs. During the hang, no %CPU is used and there is no output. Expected results: Should run forever.
