hgwatchman crash on Windows x64 using TortoiseHG

[ziriax]

I started testing watchman on Windows.

I worked fine initially, but after a while (after trying to rebase), I had a crash:

Can you locate the Watchman log file and put it up in a gist?

I'm not at a windows system at the moment so can't verify the exact path, but it should be in your %TEMP% dir; https://facebook.github.io/watchman/docs/troubleshooting.html#where-are-the-logs is up to date for unix systems but not windows systems; the concepts are the same. I think you want to look at %TEMP%\.watchman.USER.log where USER is your windows username.

I'm so sorry but my IT support reinstalled my PC last week, so I don't have the log anymore.

If the crash occurs again, I'll provide the log

OK, I'll close this out for now; please re-open if it happens again!

So far it did not crash again. Too bad that TortoiseHG spends most of its time in updating the UI; even though "hg status" now returns instantaneously, it still takes 3 seconds for TortoiseHG. That is 2 seconds less than without watchman, but still slow :-)
