Issue when sycing codes and syncing from specified tag

[Gary Chine]

Hi Chrominum Devs,

Recently I need to sync codes from specified tag like 99.0.4839.0. To save time I want to finish that based on the local codes synced from master branch.Below are steps of commands executed:

$export CR_BRANCH=99.0.4839.0
$cd src  
$gclient sync --force --nohooks --with_branch_heads --with_tags -D -v 
$git checkout -b $CR_BRANCH $CR_BRANCH 
$gclient sync --force --nohooks --with_branch_heads --with_tags -D -v (Error happened here)
$gclient runhooks -v    

See the log attahced, I think during the sync process gclient use some commit history information which is not sync to my localbranch,  it can not find the CR-Commit Postion from my git log. Does that matter. Please shine me some light.

Thanks,

Daniel

See lastchange.py ,there is no Cr-Commit-Position found from git cat-file COMMITID.So it failed. How to recover from that?

I guess you did a shallow clone.

I also followed guide here https://stackoverflow.com/questions/47087970/how-to-checkout-and-build-specific-chromium-tag-branch-without-download-the-full and I will try to add depth parameter like 1000000, 

Let me have a try and tell you the result later.

Thanks,

I'd also be careful to check your crlf settings.

Now after git checkout with large depth, I could see multiple git logs for commits, seems problem resolved for commit information missing. Thanks a lot, thumbs up!

Please let me reuse this thread to follow stuff syncing codes related for this tag branch.

Not I am being stucked on syncing src/third_party/angle although my network speed is about 800k/s. I have spend tons of time and servral times for this syncing,  one time it cost more than 4 hours for the third_party sync and failed on consequcence steps.., now I have to spend another time to continue to sync the angle and now one and half hour passed.

Hi Km,

I think you mean the break line character? I am always working on ubuntu ,does that matter

[Gary Chine]

Finally the angle syncing failed after more then 8 hours. If I want to recover from this messy, how can I, event create a new dir and resync again is an option. Thanks for your opinion.

If you're on Ubuntu, you probably don't need to worry about CRLF settings. Glad to hear that it sounds like you were able to resolve your issue.

gclient sync is just performing Git operations for most dependencies, so they should be resumable in most cases. You should be able to just run gclient sync again in most cases.
