Well, I `git stash` in src/third_party/harfbuzz-ng/src and fixed the problem. Feel free to WontFix it. But it still feels like a bug.

I think this is an old bug in gclient.
I also receive this error message from time to time.

( cd third_party/libphonenumber/dist && git reset --hard)

usually helps. (This is not specific to libphonenumber, just an example.)

alemate: why'd you assign this to me & why do you think this is a bug in gclient?

Because gclient sync sometimes fails for never-changed-locally-sources when trying to sync from some old chrome version. I believe that warx@ never changed that no-one-knows-what third-party library.

I don't know why, but if you check out and synchronize relatively old chrome (like half a year ago), and then try to switch back to ToT, it is very common for gclient sync to fail reporting unstaged changes in random third_party/ stuff.

May be it's git bug, but gclient should have workaround for that. Basically, if before synchronizing dependency there were no unstaged changes, it should probably run some git-hack to help with those git errors.

that answers the second question, but not the first :)

I'm not the right owner for this, or the best person to say whether it's a bug. I don't think it's a P1, though, regardless.

+agable & ehmaldonado for their thoughts.
