fncache: document the fact fncache is outdate at hook run time Using 'addfinalize' to generate 'fncache' means that no pending version of the file will be generated for the hooks. We would have to use the 'addfilegenerator' method to get such result. However the 'fncachevfs' (who decide that a write is necessary) have no access to the transaction to register such file generation at add time. Having the transaction accessible to the 'vfs' is too much trouble for no benefit. This outdated 'fncache' file at hook time is not expected to be an issue. The previous move from 'onclose' to 'addfinalize' had no impact on this timing. I'm documenting it now because I looked at it.

fncache: drop dedicated 'onclose' function in favor of 'tr.addfinalize' Now that we have a shiny generic mechanism, we can use it.

merge with stable

graft: drop cset description from empty commit message This is either already redundant in the output or too verbose in quiet mode.

graft: show hashes in user-facing messages Graft was in various places just showing the revision number in status messges. Instead, also show the stable and more useful short hash.

graft: give helpful warning for empty grafts It was just showing a status message with the internal revision number. Instead, show a warning like note: graft of 27:3aaa8b6725f0 "28" created no changes to commit (message tweaked in-flight by mpm)

graft: show more useful status information while grafting Show status messages with first line of commit description and names, like grafting 12:2647734878ef "fork" (tip) This gives more context for the user when resolving conflicts.

tests: test coverage for empty graft A future change will add a warning to the quiet rebase.

largefiles: drop the unfiltered repo usage in overridepurge() Now that repoview supports replacing methods, we don't need this hack.

repoview: allow methods on the proxy class to be replaced It doesn't seem to be a common idiom for repo instances, but the status() method is replaced in largefiles' purge() override. Since __setattr__ is implemented in repoview to setattr() on the unfiltered repo, the replacement method wouldn't get called unless it was invoked with the unfiltered repo, because the filtered repo remains unchanged. Since this doesn't seem to be commonly used, I didn't bother to filter out methods that perhaps shouldn't be replaced, such as changelog().
