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.)

tests: fix test-casefolding.t The message had changed, but the test was not updated. This test does not run on Linux, but failed on my Mac.

commands: print security protocol support in debuginstall Over the past week I've had to instruct multiple people to run Python code to query the ssl module to see what TLS protocol support is present. I think it would be useful for `hg debuginstall` to print this info to make it easier to access and debug why Mercurial is complaining about using an insecure TLS 1.0 protocol. Ideally we'd also print the path to the CA cert bundle. But the APIs for querying that in sslutil can emit warnings, making it slightly more difficult to integrate into `hg debuginstall`. That work will have to wait for another day.

manifest: make treemanifestctx store the repo Same as in the last commit, the old treemanifestctx stored a reference to the revlog. If the inmemory revlog became invalid, the ctx now held an old copy and would be incorrect. To fix this, we need the ctx to go through the manifestlog for each access. This is the same pattern that changectx already uses (it stores the repo, and accesses commit data through self._repo.changelog).

This is the same pattern that changectx already uses (it stores the repo, and accesses commit data through self._repo.changelog).

manifest: make manifestlog a storecache The old @property on manifestlog was broken. It meant that we would always recreate the manifestlog instance, which meant the cache was never hit. Since we'll eventually remove repo.manifest and make manifestlog the only property, let's go ahead and make manifestlog the @storecache property, have manifestlog own the manifest instance, and have repo.manifest refer to it via manifestlog. This means all accesses go through repo.manifestlog, which is now invalidated correctly.

manifest: move manifest creation to a helper function A future patch will be moving manifest creation to be inside manifestlog as part of improving our cache guarantees. bundlerepo and unionrepo currently rely on being able to hook into manifest creation, so let's temporarily move the actual manifest creation to a helper function for them to intercept. In the future manifest.manifest() will disappear entirely and this can disappear.
