Hang in downloading buildtools/mac/gn.sha1

[Avi Drissman]

I'm trying to "gclient sync" and I keep getting a hang:

/V/s/c/src ((cebcfd84a5f1...))> gclient sync

Any suggestions for diagnosing this?

Thanks!

What happens if you:

1) gsutil.py stat gs://chromium-gn/b8db422af70c716836c579dad9153c687ab54f7c

2) gsutil.py cp gs://chromium-gn/b8db422af70c716836c579dad9153c687ab54f7c /tmp/foo

3) download_from_google_storage --no_resume --platform=darwin --no_auth --bucket chromium-gn -s src/buildtools/mac/gn.sha1

Apologies.

This hung last night overnight, and hung this morning right before I sent this email, but of course now that I sent the email it works great.

Thank you anyway.

It's hanging again on a different file, always on that one file (src/v8/test/fuzzer/wasm.tar.gz.sha1 this time). When I do that first diagnostic step of statting that gs:// bucket, it hangs:

/V/s/c/src (dialog-trunk) [1]> 

gsutil.py stat gs://chromium-gn/b8db422af70c716836c579dad9153c687ab54f7c

What version of depot_tools are you running?

So again it magically started working after a few hours.

When I do git log in the depot_tools folder, it's e0a1afbf4b0d41b10d9eb1463835647024eb25bc.

I'm having the same issue as Avi, also with wasm.tar.gz.sha1

Same hash for depot_tools

Hmm that

Your "Oauth 2.0 User Account" credentials are invalid. For more help, see "gsutil help creds", or re-run the gsutil config command (see "gsutil help config").

is a bit suspicious. Did you see that only when hitting CTRL-C  or did show up before? Does it show consistently when failing?

avi@ if it happens again can you plz run this time:

gsutil.py -DD stat gs://chromium-gn/b8db422af70c716836c579dad9153c687ab54f7c

(note the -DD)

and attach the output to a RVG crbug?

That will spit out all the debugging X- headers which contain link to the backend traces (But also your Oauth2 bearer, hence mind the RVG)

No, it would just silently hang. I only saw that line when I used control-C. Plus, it was only jamming on one specific file. Surely that one file wasn't looking for a specific credential different from the others.

I'll keep an eye out for it happening again and will run that line for you.

Thank you for your help in this.
