hgweb: simplify now that we always have a single path Both `templatedir()` and `web.templatepath` are now always a single path (or None). Differential Revision: https://phab.mercurial-scm.org/D8788

templater: simplify stylemap() now that templatedir() returns a single path Differential Revision: https://phab.mercurial-scm.org/D8787

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. 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. We start with easy and small cleanup. Differential Revision: https://phab.mercurial-scm.org/D8708

commitctx: consider removed as touched This achieve the same result with clearer code. 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. We start with easy and small cleanup. Differential Revision: https://phab.mercurial-scm.org/D8707

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. 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. We start with easy and small cleanup. Differential Revision: https://phab.mercurial-scm.org/D8706

commitctx: more filesremoved assignment closer to removed computation A small change that makes the code flow clearer. 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. We start with easy and small cleanup. Differential Revision: https://phab.mercurial-scm.org/D8704

commitctx: compute files added from _filecommit returns When possible, lets avoid recomputing the same information again. 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. We start with easy and small cleanup. Differential Revision: https://phab.mercurial-scm.org/D8703

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. 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. We start with easy and small cleanup. Differential Revision: https://phab.mercurial-scm.org/D8702

relnotes: add release notes for relevant changes I did since the 5.4 release After having written the notes, I realized that the added points contain changes that were part of the 5.4.2 release. These were never included in any release notes. I asked on IRC whether they should be added to this file or not, but didn’t get an answer to this question. If they should not be added here, I can remove them. Differential Revision: https://phab.mercurial-scm.org/D8770

relnotes: fix indentation The two points were written by me. For some reason, I missed the fact that the other points were indented by one space. Differential Revision: https://phab.mercurial-scm.org/D8769
