tests: make check-py3-compat.py actually load the specified files correctly For most uses, this change is essentially a no-op, as this script is generally only run by test-check-py3-compat.t, which will already put `$TESTDIR/..` in `$PYTHONPATH`. When running outside of tests, however, `$PYTHONPATH` is likely not set, causing check-py3-compat.py to parse the file from the repo, but then import the installed version, and raise any errors about the installed version, not the one currently in the repo. Additionally, this helps users (like me) who have a strange set up where their home directory (and thus their hg repos) happen to be in a subdirectory of sys.prefix (which is /usr on my system). Since the '.' entry added to sys.path takes precedence over the absolute path of `$TESTDIR/..` in `$PYTHONPATH`, the path to the modules that it imports (and that show up in any stack trace) are *relative*, meaning that we don't detect them as starting with `sys.prefix`. Sample non-test invocation, and the difference this change makes (the path for 'error at <path>:<line>' is correct now):: Before: ``` $ python3 contrib/check-py3-compat.py mercurial/win*.py mercurial/win32.py: error importing: <ValueError> _type_ 'v' not supported (error at check-py3-compat.py:65) mercurial/windows.py: error importing: <ModuleNotFoundError> No module named 'msvcrt' (error at check-py3-compat.py:65) ``` After: ``` $ python3 contrib/check-py3-compat.py mercurial/win*.py mercurial/win32.py: error importing: <ValueError> _type_ 'v' not supported (error at win32.py:11) mercurial/windows.py: error importing: <ModuleNotFoundError> No module named 'msvcrt' (error at windows.py:12) ``` Differential Revision: https://phab.mercurial-scm.org/D8814

templater: handle None returned from templatedir() My recent 91aa9bba3dc9 (templater: make templatepaths() return a single path, or None, 2020-07-21) didn't account for the fact that `templatedir()` returns `None` in frozen binaries. That is ironic, since the reason I'm working on this is to add support for built-in mapfiles in frozen binaries. This patch updates the callers to handle the `None` case. It's somewhat ugly, but I will have to revisit this soon anyway, since my goal is to make all callers handle that case by trying to read the map file using the resources API instead. Differential Revision: https://phab.mercurial-scm.org/D8810

templater: do search for include of unqualified builtin outside of config code Commit 081b08e4ea13 (templater: look for mapfiles in template paths, 2015-05-15) added support for using things like `%include map-cmdline.default` to include built-in map files without using a valid path to them. This patch rewrites that support by moving it into `_readmapfile()` so it can later be adapted for reading from a non-file resource. Differential Revision: https://phab.mercurial-scm.org/D8792

templater: switch to lower-level config.parse() in _readmapfile() I hope to modify this code to also work with resources loaded from memory (for PyOxidizer support). For that, we'll need to handle the lookup of relative `%include` path (not joined with the base directory of the containing file). This patch prepares for that by using `config.parse()` instead of `config.read()`, since the latter expects a file in the file system. As it happens, this change also lets us clean up the `config` class to not need the `_includepaths` field. That will happen next. Differential Revision: https://phab.mercurial-scm.org/D8791

config: pass both relative and absolute paths to `include` callback The `include` callback is responsible for loading configs from `%include` statements. The callback currently gets passed the absolute path [1] to the config to read. That is created by joining the dirname of the file that contains the `%include` statement. For PyOxidizer support, I'm trying to reduce dependence on paths. This patch helps with that by passing the relative path found in the `%include` statement (but with username expansion, etc.) to the `include` callback. It also turns out that the existing callers can easily adapt to using the relative path. Coming patches will clean that up and then we'll remove the absolute path from the callback. [1] The "absolute path" bit is a bit of a lie -- it's going to be an absolute path if the path that was passed into `config.parse()` was absolute. Differential Revision: https://phab.mercurial-scm.org/D8790

tests: add test for bad template %include and __base__ It doesn't seem like we had any tests for `%include non-existent` and `__base__ = non-existent`. The latter raises an error while the former ignores the include. We should probably also make the former an error. Differential Revision: https://phab.mercurial-scm.org/D8798

tests: add test for unqualified include of a built-in template map The feature was added in 081b08e4ea13 (templater: look for mapfiles in template paths, 2015-05-15), but no test case was added. Differential Revision: https://phab.mercurial-scm.org/D8797

commitctx: extract _filecommit too This function is exclusively used in `commitctx`. So we should extract it too for consistency and to reduce the `localrepo` bloat. This is part of a larger refactoring/cleanup of the commitctx code to clarify and augment the logic gathering metadata useful for copy tracing. The current code is a tad too long and entangled to make such update easy. Differential Revision: https://phab.mercurial-scm.org/D8710

commitctx: extract the function in a dedicated module the function have few callers (< 15) is quite long a mostly independent from the repository itself. It seems like a good candidate to reduce the bloatness of the localrepository class. Extracting it will help us cleaning the code up and splitting it into more reasonable-size function. We don't use a copy trick because the amount of code extract is quite small (<5%) and the de-indent means every single line change anyway. So this is not deemed valuable to do so. This is part of a larger refactoring/cleanup of the commitctx code to clarify and augment the logic gathering metadata useful for copy tracing.

templater: make templatepaths() return a single path, or None The function returns either a singleton list or an empty list, so it makes more sense to return a value or None. The plural in the name also doesn't make sense, but `templatepath()` is already taken, so I renamed it to `templatedir()` instead. Differential Revision: https://phab.mercurial-scm.org/D8786

templater: simplify templatepaths() to avoid iterating a singleton list The function iterates over a hard-coded list of one element since d844e220792a (templater: don't search randomly for templates - trust util.datapath, 2014-09-28). Differential Revision: https://phab.mercurial-scm.org/D8785

commitctx: move a tiny else clause above the very long one This is simple to have all the simple case unfold before the 100+ line one. Otherwise it is hard to relate the `else` to the initial conditionnal.

commitctx: rename "changed" to touched The variable contains content that are both added and modified. "changed" could be confused with "modified" only, so we pick a less ambiguous naming that will help with more unification. For example, it would make sense to shove the "removed" item in there since this is how the variable is used.

commitctx: compute files added from _filecommit returns When possible, lets avoid recomputing the same information again.

commitctx: return "touched" status from _filecommit Instead of mutating a list passed in argument, we simply return the information from the `_filecommit` function. This make for a cleaner API and allow for richer information to be returned. That richer information will be used in the next commit to avoid duplicated computation.

strip: with --keep, consider all revs "removed" from the wcp (issue6270) The current code was blink to change from other branches when stripping merges that are ancestors of the working copy parents.

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.

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.

hgweb: compatibility of hgweb.cgi template with Python 3 When running Mercurial on Python 3 hgweb expects the config variable to be a bytestring.
