dirstate: don't remove normallookup files from nonnormalset The dirstate typically tries to keep the nonnormalset and otherparentset up-to-date when making changes to the dirstate. In the case of files marked normallookup, however, it erroneously removes the file from the nonnormalset, after _addpath had just added it. This doesn't seem to matter at the moment, as nothing relies on the nonnormalset being correct at this point, however a future re-implementations of the dirstate map will require this to be kept up-to-date correctly.

dirstate: clear map cached properties when clearing the map dirstatemap.clear should remove all record of the files in the map. This includes removing caches of values derived from these. Differential Revision: https://phab.mercurial-scm.org/D1338

util: add util.clearcachedproperty This utility function allows clearing of the cached value set up @propertycache, if there is one. Differential Revision: https://phab.mercurial-scm.org/D1337

changegroup: use any node, not min(), in treemanifest's generatemanifests This is fixing quadratic behavior, which is probably not noticeable in the common case, but if a very large directory gets added here, it can get pretty bad. This was noticed because we had some pushes that spent >25s in changegroup generation calling min() here, according to profiling. The original reasoning for min() being used in 829d369fc5a8 was that, at that point in the series, we were adding almost everything to tmfnodes during the first iteration through the loop , so we needed to avoid sending child directories before parents. Later changes made it so that the child directories were added only when we visited the parent directory (not all of them on the first iteration), so this is no longer necessary - there won't be any child directories in tmfnodes before the parents have been sent. This does mean that the manifests are now exchanged unordered, whereas previously we would essentially do [a, b, b/c, b/c/d, e], we now can send a, b, and e in any order; b/c must still follow b, and b/c/d must still follow b/c.

bundle: allow bundlerepo to support alternative manifest implementations With our treemanifest logic, the manifests are no longer transported as part of the changegroup and are no longer stored in a revlog. This means the self.manifestlog line in bundlerepo.filestart no longer calls _constructmanifest, and therefore does not consume the manifest portion of the changegroup, which means filestart is not populated and we result in an infinite loop. The fix is to make filestart aware that self.manifestlog might not consume the changegroup part, and consume it manually if necessary. There's currently no way to test this in core, but our treemanifest extension has tests to cover this. Differential Revision: https://phab.mercurial-scm.org/D1329

obsfate: makes successorsetverb takes the markers as argument Right now, successorsetverb only needs successors to compute the verb. But we will want use additional information (effect-flags and operation) in the near future to compute a better verb. Add the markers parameter now so extensions (like Evolve) could wrap the function and start experimenting around better obsfate verbs. As successorsetverb now takes both successorset and markers parameters, rename it to obsfateverb, successorsetandmarkersverb was too long. Differential Revision: https://phab.mercurial-scm.org/D1191

scmutil: don't try to delete origbackup symlinks to directories (issue5731) When origbackuppath is set, when looking to see if a file we are backing up conflicts with a directory in the origbackuppath, we incorrectly match on symlinks to directories. This means we try to call vfs.rmtree on the symlink, which fails. Differential Revision: https://phab.mercurial-scm.org/D1311

tests: add a test demonstrating issue5731 If origbackups are in use, a symlink to a valid directory is backed up, and an update is made that attempts to backup a file or link over that symlink, we abort with a bad error message instead of successfully updating.

cmdutil: create dirs for templated cat file output Previously, the caller was responsible for creating the directory structure of files written out using a path template. This is onerous, especially if the exact filenames are not known upfront, but are being accessed via a matcher. This patch changes things so that hg will attempt to create the appropriate directories before writing the output file. Differential Revision: https://phab.mercurial-scm.org/D1332

cat: test output path behvaior when target path does not exist In the next patch, we will change the behavior of the cat command to create output file parent directories before attempting to write the output file. This patch documents the current unfortunate behavior. Differential Revision: https://phab.mercurial-scm.org/D1331
