dirstate: fix debug.dirstate.delaywrite to use the new "now" after sleeping It seems like the a regression has sneaked into debug.dirstate.delaywrite in 6c6b48aca328. It would sleep until no files were modified "now" any more, but when writing the dirstate it would use the old "now" and still mark files as 'unset' instead of recording the timestamp that would make the file show up as clean instead of unknown. Instead of getting a new "now" from the file system, we trust the computed end time as the new "now" and thus cause the actual modification time to be writiten to the dirstate. debug.dirstate.delaywrite is undocumented and only used in test-largefiles-update.t . All tests seems to work fine for me without debug.dirstate.delaywrite . Perhaps because it not really worked as intended without the fix in this patch, and code and tests thus have evolved to do fine without it? It could thus perhaps make sense to drop usage of this setting in the tests. That could speed the test up a bit. This functionality (or something very similar) can however apparently be very convenient in setups where checking dirty-ness is expensive - such as when using large files and have slow file filesystems or are CPU constrained. Now it works and we can try it. (But ideally, for the largefile use case, it should probably only delay lfdirstate writes - not ordinary dirstate.)
