automation: upgrade to latest packages in requirements.txt Let's stay modern. Differential Revision: https://phab.mercurial-scm.org/D6785

localrepo: push manifestlog and changelog construction code into store This feels substantially more appropriate, as the store is actually the layer with knowledge of how to handle this storage. I didn't move the caching decorators for now because that's going to require some more involved work, and this unblocks my current experimentation.

notify: add option for deterministic message-id generation Copied from email by durin42: > Pierre-Yves asked offline why I asked a new option for this and why it > is not the default. Message-Id is supposed to be unique world-wide and > while it is desirable to have a deterministic mechanism for them for > creating follow-up emails, it needs organisational control for ensuring > the uniqueness.

uncommit: add options to update to the current user or current date These are also from the evolve extension's version of uncommit. I tried adding validation that both forms of user or date can't be specified at the same time, but that fails because these show up in `opts` with a None value whether or not the option was given on the command line. Presumably that means the conditional in `resolvecommitoptions` could be simplified. But this is how both evolve and MQ handle it. Differential Revision: https://phab.mercurial-scm.org/D6828

uncommit: add support to modify the commit message and date Currently, the evolve extension's version of this command supports it. Differential Revision: https://phab.mercurial-scm.org/D6827

run-tests: add a dedicated 'isoptional' function This is clearer than repeated manual call to to 'endswith'. (This is a gratuitous cleanup that I made while investigating a bug).

run-tests: remove the artificial indentation

run-tests: extract a `process_out_line` from the main function The main function doing line comparison is quite complex. Slicing it in smaller piece should clarify it. To avoid a huge diff, the code is kept at the same indentation. We'll re-indent in the next changesets. (This is a gratuitous cleanup that I made while investigating a bug).

run-tests: extract a `process_cmd_line` from the main function The main function doing line comparison is quite complex. Slicing it in smaller piece should clarify it. (This is a gratuitous cleanup that I made while investigating a bug).

changegroup: move message about added changes to transaction summary Before that, applying multiple changegroups in the same transaction issued the message multiple time. This result in a confusing output: adding changesets adding manifests adding file changes added 32768 changesets with 60829 changes to 2668 files adding changesets adding manifests adding file changes added 8192 changesets with 16885 changes to 1553 files adding changesets adding manifests adding file changes added 1020 changesets with 1799 changes to 536 files adding changesets adding manifests ... Instead, we now only issue the message once at the end of the transaction, summing up all added changesets, changes and files. The line is identical, but happens sightly later in the output. There are other suboptimal behavior around issue multiple changegroup (eg: progress bar). We'll cover them later. This impact of lot of test as one would expect, but a two pass check show they are just the order change we expected. To deal with "under the hood" bundle application by internal code, we had to take a slightly hacky move. We could clean that up with a more official way to enter "under the hood" section, however I want to keep this series simple to get it landed. This kind of change have a very high bit rot rate since it impact a lot of test output.
