cluefs's Issues
traces format
hi,
I haven't looked into cluefs traces' event format but I suppose it would be great to use chromium traces' format so these traces could be analyzed with the nice trace-viewer they've developed:
https://www.chromium.org/developers/how-tos/trace-event-profiling-tool
https://github.com/google/trace-viewer
trace-event format
Go runtime is now using this when launched in profiling/tracing mode and it's a breeze to inspect and debug performance profiles.
Building with recent tools
- The uploaded binaries are not useful to me, I need linux-arm64
- The build instructions no longer with with current go
I've tried this
FROM golang:bookworm AS base
RUN go install github.com/airnandez/cluefs@latestbut that fails with
> [build-install 1/1] RUN go install github.com/airnandez/cluefs@latest:

Create a cluefs package which could be embedded in other applications
Hi there, are you still interested in creating a cluefs package? Because I am interesting in using it in my application :)
If you are ok with that, I will start working on it in my fork ( https://github.com/rfjakob/cluefs ) and send a pull request once it is ready.
Doesn't support Fsync?
When using VIM on CentOS 7.5, whenever I save a file, I see this error:
"/tmp/trace/nanofile.txt"
"/tmp/trace/nanofile.txt" E667: Fsync failed
WARNING: Original file may be lost or damaged
don't quit the editor until the file is successfully written!
Press ENTER or type command to continue
Does cluefs not support fsync?
Rename does not work
Renaming a file leaves the renamed file in a broken state that is only fixed by unmounting and mounting again:
$ echo foo > foo.txt
$ ls -l
-rw-rw-r--. 1 jakob jakob 4 7. Sep 20:58 foo.txt
$ mv foo.txt bar.txt
$ ls -l
----------. 0 root root 0 1. Jan 1970 bar.txt
$ rm bar.txt
rm: cannot remove ‘bar.txt’: Input/output error
