--debug_http doesn't work with --enable-storage-client-library=true

[MattIrv]

Describe the bug

I was trying to debug another issue and finding that the --debug_http flag documented in https://github.com/GoogleCloudPlatform/gcsfuse/blob/master/docs/mounting.md doesn't seem to make any difference on the log output when using --enable-storage-client-library=true

To Collect more Debug logs
Steps to reproduce the behavior:

1. Please make sure you have no other security, monitoring, background processes which can offend the FUSE process running. Possibly reproduce under a fresh/clean installation.
2. Please rerun with --debug_fuse --debug_fs --debug_gcs --debug_http --foreground as additional flags to enable debug logs.
3. Monitor the logs and please capture screenshots or copy the relevant logs to a file (can use --log-format and --log-file as well).
4. Attach the screenshot or the logs file to the bug report here.
5. If you're using gcsfuse with any other library/tool/process please list out the steps you took to reproduce the issue.

With default --enable-storage-client-library

1. gcsfuse --debug_fuse --debug_fs --debug_gcs --debug_http --foreground _ mp
2. ls mp/<bucket>
3. Log output doesn't contain HTTP logs: logs-gcs-library.txt

It also happens with JSON format logs and when outputting to a log file instead of to stdout

With --enable-storage-client-library=false

1. gcsfuse --debug_fuse --debug_fs --debug_gcs --debug_http --foreground --enable-storage-client-library=false _ mp
2. ls mp/<bucket>
3. Log output contains HTTP logs (trimmed): logs-gcloud-library.txt

System (please complete the following information):

• OS: Ubuntu 22.04
• Platform: VM (GCE)
• Version:

$ gcsfuse -v
gcsfuse version 0.42.3 (Go version go1.19.5)

Hi @MattIrv,

Thanks for reporting!

This is a valid bug that --debug_http flag doesn't work with --enable-storage-client-library=true.

To fix this issue, there is a dependency on go-storage-client library team, right now no API available in go-storage-client library using that we can write the traces.

We have created a bug for this issue our side. I'll update this thread, once we finalize something for this issue.

Regards,
Prince Kumar.

Hi @MattIrv,

We discussed this issue within the team and decided to not support this flag for storage-client library. We have updated the help description for --debug_http flag accordingly.
