test-strip: display more information highlight buggy behavior When using `hg strip --keep` on a set of changeset that contains a merge, the set of file considered when rebuilding the dirstate is missing files updated by changeset that are not directly inside the `new-parent::old-parent` range. We start with updating the test with new output highlighting the issue. This issue was spotted because that dirstate inconsistency made the test flaky. The new command make the test less flaky (but still wrong).

py3: fix formatting of LookupError for workingctx Spotted while writing broken tests for "hg grep -fr'wdir()'". basectx._fileinfo() raises ManifestLookupError(self._node, ..), but _node of the workingctx is None for historical reasons.

log: fix crash and bad filematcher lookup by -fr'wdir()' PATH "-fr'wdir()' ADDED-PATH" is still wrong, which will be fixed in default branch.

hgdemandimport: bypass demandimport for _ast module (issue6407) This is broken on Python 3.9rc1, and while it sounds like there may be a fix in Python, we probably also should have this workaround in place in hg. See the bug for more details (including on bugs at redhat and b.p.o). Differential Revision: https://phab.mercurial-scm.org/D9004

repoview: pin revisions for `local` and `other` when a merge is active I've hit this a couple of times, where pulling with a dirty `wdir` obsoletes `p1` and updating to the successor results in merge conflicts. The problem was resolving them failed immediately, complaining that the old checkout was filtered. The change in `test-rebase-obsolete.t` is because there's an outstanding merge conflict in a rebase operation. The summary prompt to merge seems incorrect for this scenario, but that's an existing issue. Differential Revision: https://phab.mercurial-scm.org/D8980

hgweb: compatibility of hgweb.cgi template with Python 3 When running Mercurial on Python 3 hgweb expects the config variable to be a bytestring. The solution proposed by Anton Shestakov is to use a byteprefix to the literal string defined cgi script as provided in this patch for hgweb.cgi, contrib/hgweb.fcgi and contrib/hgweb.wsgi. I am not sure whether this covers all relevant templates, but I couldn't find others. Differential Revision: https://phab.mercurial-scm.org/D8978

genosxversion: don't give up if we can't find a path to hg libraries This doesn't work if you have a PyOxidized hg on $PATH, but everything is fine if you just ignore that problem. Differential Revision: https://phab.mercurial-scm.org/D8975

tests: fix test-demandimport.py on Python 3.9 Starting with Python 3.9, importing importlib.resources (indirectly) imports the zipfile module. Therefore, the module is not suitable for the test. Instead, we can use the ftplib module, which is very unlikely to be imported during the test run.

test: add `test-repo` requirement to `test-check-format` (issue6395) Kindly reported by Tristan Seligmann <mithrandi@mithrandi.net>

keepalive: Do not append _rbuf if _raw_readinto exists (issue6356) The readline method append to the chunks the content of the _rbuf then there is a loop that call _raw_read which on Python3 call readinto. But the readinto version in mercurial append again the _rbuf content. So this creates the duplicate content. This does not happen in Python2 because _raw_read does not call readinto.

mergestate: fix BC breakage introduced because of removal of a merge record In fcd0cff3400a I removed the usage of RECORD_RESOLVED_OTHER. However I also removed the reading support, hence if there is any user who runs into merge conflict with older version of hg, upgrades hg and then tries to read mergestate, they will end up with an MergeRecordUnsupportedError.

rebase: fix regression in file change detection introduced by 0ecb3b11fcad Before 0ecb3b11fcad, `wctx._compact()`, was called by `wctx.nofilechanges()` as a side effect. Later, it turned out that this side effect is needed to correctly detect which files changed. See https://phab.mercurial-scm.org/D8733#131949 for the history. The problem could also be triggered by running `tests/test-rebase-parameters.t` with `--extra-config-opt rebase.experimental.inmemory=1`. Differential Revision: https://phab.mercurial-scm.org/D8843

push: test for checks preventing publishing obsolete changeset The main difference from the previous test is how the changeset was obsoleted. In this case it is an amend so publishing the orphan would also create phase divergence. This must not go unnoticed.

push: another test for checks preventing pushing orphaness to a server In this one, orphan was create with and amend instead of a prune.
