WebRTC Native. cannot pass through "gclient sync" step

[Ilya Malyavskiy]

Hello Everyone. I'm new here and experiencing troubles with native libraries building.

I've fetched the master of the repository. Then executing "gclient sync" the output is the following:

=========================

Syncing projects:  36% (12/33) src/third_party                           

                                                                         

src/third_party (ERROR)                                                  

----------------------------------------                                 

[0:00:02] Started.                                                       

[0:00:29] From https://chromium.googlesource.com/chromium/src/third_party

[0:00:29]    66bea27c42f..09ab2e00816  master     -> origin/master       

----------------------------------------                                 

Error: 6>

6>      You have unstaged changes.                                       

6>      Please commit, stash, or reset.                                  

=========================

This step passes well at 65th branch. But not on the master. 

May be I am doing something wrong?.. Any opinions?

6>      You have unstaged changes.                                       

6>      Please commit, stash, or reset.           

This is likely something left over in one of the repos that "gclient sync" tries to write to.

Dilligent use of "git status" (possibly iterating over the subdirectories) may uncover the culprit.

Thank you for fast reply. I've just tested the 65th branch too and behavior is almost the same. Seems like you definitely right about things left after prev. sync.

Got the reason of such kind failures: windows has a limitation for path length. If this limitation is exceeded the webrtc build system may report may not report... some strange errors can appear and so on.... so I would recommend to add some notice to do not put the webrtc-checkout folder to any place then a root dir of some local drive. And also take this point into account for the webrtc stuff updates to be aware that paths cannot exceed some maximum length.

Just for posterity: the issue is still there, never been resolved (https://bugs.chromium.org/p/webrtc/issues/detail?id=8843), but there's a simple workaround which might worth mentioning in the WebRTC native API primer: adjust you Git config with "git config --system core.longpaths true", and all of a sudden it all works.

So at the end of the day it's a actually an issue with the default Git config on Windows.

It's worth noting the 260 character path limit can be easily removed via registry "hacks" by following a guide like this. Maybe syncing should also modify the registry to remove the limitation, or at least prompt for it

[Vitaly Ivanov]

It doesn't help. I had long paths enabled in the registry, but it still failed

So, for posterity what is Google's official O/S then ?
