graphlog: document what "_" and "*" mean Documenting "*" should've been a part of 9b3f95d9783d, but I somehow didn't notice that the symbols are explained in the command's help text.

tests: expand test coverage for updating phases Consolidating the tests demonstrated that there are behavior differences when pushing phases between bundle1 and bundle2. A reason for this is the behavior of legacy pushes where the client queries the state of phases and then conditionally updates phases after an "unbundle" is processed. This behavior is expected. The tests were incomplete because they only tested the case of a publishing repo. In this commit, we add a variant for a non-publishing repo. We still see some differences between the legacy and bundle2 exchanges. But they are less pronounced. The behavior of not firing a pushkey hook when phases are updated as part of changegroup application feels weird to me. I'm not sure if this is a feature or a bug. By the time the "pushkey" or "phases" bundle2 part is applied, the phases have already been moved on a publishing repository. We fire the "pushkey" hook regardless, even though it would be a no-op. This is the part that feels the most buggy.

tests: consolidate test-push-http.t and test-push-http-bundle1.t These tests were initially copies of each other. Now that we have #testcases support in .t tests, we can consolidate them. The changes to test-push-http.t reflect the differences between that file and test-push-http-bundle1.t. The variances in phases push behavior are the biggest differences. The test will be updated in a subsequent commit to make the differences more clear and to expand test coverage. For now, let's just port the differences verbatim to get the tests consolidated.

tests: port value-less unbundle capability test to test-push-http.t This test is present in test-push-http-bundle1.t. Let's add it to test-push-http.t to further unify the tests.

tests: add phase testing to test-push-http-bundle1.t test-push-http.t and test-push-http-bundle1.t were initially copies. Now that we have support for inline test variants, we can combine them. One of the variances between the tests is testing of phase moving. We add the missing code to test-push-http-bundle1.t.

date: fix parsing months Thanks nemo for discovering this on #mercurial IRC channel. Test Plan: Add a test.

tests: allow age to go up to triple digits in test-shelve.t We started to glob the age of shelved changes in 51934fc796c0, which says that sometimes tests run slow and `hg shelve --list` says "2s" instead of "1s". However in some instances, like [1], tests run so slow that the age goes up to double digits ("13s" in that case). When that happens, `hg shelve --list` output has less white spaces after the age, so let's glob the spaces too. We probably won't ever need to handle triple digits there, but I went ahead and left only 2 required white spaces in total.

fileset: don't abort when running copied() on a revision with a removed file It looks like AND with any status-y fileset would trigger this, as added() and removed() also failed. The 4.5-rc revision is a convenient test case, but the merge isn't necessary.

revset: evaluate filesets against each revision for 'file()' (issue5778) After f2aeff8a87b6, the fileset was evaluated to a set of files against the working directory, and then those files were applied against each revision. The result was nonsense. For example, `hg log -r 'file("set:exec()")'` on the Mercurial repo listed revision 0 because it has the `hg` script, which is currently +x. But that bit wasn't applied until revision 280 (which 'contains()' properly indicates). This technique was borrowed from checkstatus(), which services adds(), modifies(), and removes(), so it seems safe enough. The 'r:' case is explicitly assigned to wdirrev, freeing up rev=None to mean "re-evaluate at each revision". The distinction is important to avoid behavior changes with `hg log set:...` (test-largefiles-misc.t and test-fileset-generated.t drop current log output without this). I'm not sure what the right behavior for that is (1fd352aa08fc explicitly enabled this behavior for graphlog), but the day before the release isn't the time to experiment.

test-bookmarks-pushpull: stabilize for Windows

makefile: add Ubuntu Artful docker targets (.deb and ppa) Artful Aardvark was released on 2017-10-19 and will be supported until 2018-07.

bundle2: fix the formatting of the stream part requirements Use the same pre-encoded normalization as bundlespecs for the stream v2 part requirements. As it touch the wire protocol, it needs to change before the release. This was spotted by Gregory Szorc. Differential Revision: https://phab.mercurial-scm.org/D1950

streamclone: extract requirements formatting It will be reused for the formatting of the requirements of the stream v2 part requirement and later for the stream v2 requirements. Differential Revision: https://phab.mercurial-scm.org/D1949

bookmarks: fix pushkey compatibility mode (issue5777) The namespace used for the compatibility mode was missing a trailing 's'.

lazymanifest: avoid reading uninitialized memory I got errors running tests with clang UBSAN [1] enabled. One of them is: ``` --- test-dirstate.t +++ test-dirstate.t.err @@ -85,9 +85,115 @@ $ echo "[extensions]" >> .hg/hgrc $ echo "dirstateex=../dirstateexception.py" >> .hg/hgrc $ hg up 0 - abort: simulated error while recording dirstateupdates - [255] + mercurial/cext/manifest.c:781:13: runtime error: load of value 190, which is not a valid value for type 'bool' + #0 0x7f668a8cf748 in lazymanifest_diff mercurial/cext/manifest.c:781 + #1 0x7f6692fc1dc4 in call_function Python-2.7.11/Python/ceval.c:4350 + ....... + SUMMARY: UndefinedBehaviorSanitizer: invalid-bool-load mercurial/cext/manifest.c:781:13 in + [1] $ hg log -r . -T '{rev}\n' 1 $ hg status - ? a ``` While the code is not technically wrong, but switching the condition would make clang UBSAN happy.

unamend: fix command summary line Before this patch, the docstring started with a newline, which led the summary line (shown in e.g. `hg help -c`) to be blank. Differential Revision: https://phab.mercurial-scm.org/D1943

lfs: don't require the .hglfs file to be tracked to control the policy The .hgignore file doesn't need to be tracked, nor does the git equivalent of this file. I'm still a little concerned about the effects of forgetting to commit this file. But the fact that conversions maintain the hashes if only the normal vs external storage changes, should make this less risky.
