py: error out if a "skip" character was given with non-dict to util.dirs() util.dirs() keeps track of the directories in its input collection. If a "skip" character is given to it, it will assume the input is a dirstate map and it will skip entries that are in the given "skip" state. I think this is used only for skipping removed entries ("r") in the dirtate. The C implementation of util.dirs() errors out if it was given a skip character and a non-dict was passed. The pure implementation simply ignored the request skip state. Let's make it easier to discover bugs here by erroring out in the pure implementation too. Let's also switch to checking for the dict-ness, to make the C implementation (since that's clearly been sufficient for many years). This last change makes test-issue660.t pass on py3 in pure mode, since the old check was for existence of iteritems(), which doesn't exist on py3.

rust-filepatterns: unescape comment character property There were multiple issues in the original implementation: a. the local variable "line" dropped soon after replace_slice() applied b. replace_slice() was noop since br"\#".len() != b"#" This patch uses bytes::Regex::replace_all() since it seems the simplest way to replace bytes of arbitrary length, and I don't think we have to avoid using Regexp here.

rust-filepatterns: use literal b'#' instead of cast

rust-filepatterns: fix type of warnings tuple to (bytes, bytes) Otherwise warn() in match.py would fail if the warning contains non-ASCII character. We might want to add a thin ByteString wrapper around Vec<u8> to implement ToPyObject<ObjectType = PyBytes>, but I'm not sure.

hgignore: add escape syntax test for glob patterns The last example, [\#], is what the rust implementation fails to parse. The other escapes can be removed by regexp engine or _globre().

hgignore: add a few more weird patterns to test case

hgignore: update \-escape test to reflect actual behavior "\\<char>" is not an escape character but "\\" + <char>.

py3: add a b'' prefix in tests/test-convert-identity.t Differential Revision: https://phab.mercurial-scm.org/D6662

lookup: don't use "00changelog.i@None" when lookup of prefix fails We were shadowing the "node" variable, so we always passed None to the LookupError instead of the node we meant to pass. (This showed up in py3 tests since py3 doesn't like to format None using "%s".) Differential Revision: https://phab.mercurial-scm.org/D6661

shelve: modify help text on --interactive We now have `unshelve --interactive` after rHG5162753c4c14. So, the help text on `shelve --interactive` suggesting that it only works for `shelve` can be removed. Differential Revision: https://phab.mercurial-scm.org/D6654

unshelve: mark unshelve interactive as experimental This is a follow-up patch to rHG5162753c4c14. We have the logic for interactive unshelve under `_rebaserestorecommit()`. So, we might get conflicts even if there are conflicting changes other than selected changes by the user. We should mark unshelve `--interactive` as `EXPERIMENTAL` until we solve this issue.

commit: improve the files field of changelog for merges Currently, the files list of merge commits repeats all the deletions (either actual deletions, or files that got renamed) that happened between base and p2 of the merge. If p2 is the main branch, the list can easily be much bigger than the change being merged. This results in various problems worth improving: - changelog is bigger than necessary - `hg log directory` lists many unrelated merge commits, and `hg log -v -r commit` frequently fills multiple screens worth of files - it possibly slows down adjustlinkrev, by forcing it to read more manifests, and that function can certainly be a bottleneck - the server side of pulls can waste a lot of time simply opening the filelogs for pointless files (the constant factors for opening even a tiny filelog is apparently pretty bad) So stop listing such files as described in the code. Impacted merge commits and their descendants get a different hash than they would have without this. This doesn't seem problematic, except for convert. The previous commit helped with that in the hg->hg case (but if you do svn->hg twice from scratch, hashes can still change). The rest of the description is numbers. I don't have much to report, because recreating the files list of existing repositories is not easy: - debugupgradeformat and bundle/unbundle don't recreate the list - export/import tends to choke quickly applying patches or on description that contain diffs, - merge commits from the convert extension don't have the right files list for reasons orthogonal to the current commit - replaying the merge with hg update/hg merge/hg revert --all/hg commit can end up failing in hg revert - I wasn't sure that using debugsetparents + debugrebuilddirstate would really build the right thing I measured commit time before and after this change, in a case with no files filtered out, several files filtered out (no difference) and 5k files filtered out (+1% time). Recreating the 100 more recent merges in a private repo, the concatenated uncompressed files lists goes from 1.12MB to 0.52MB. Excluding 3 merges that are not representative, then the size goes from 570k to 15k. I converted part of mozilla-central, and observed file list shrinking quite a bit too, starting at the very first merge, 733641d9feaf, going from 550 files to 10 files (although they have relatively few merges, so they probably wouldn't care).

convert: add a config option to help doing identity hg->hg conversion I want to change the computation of the list of files modified by a commit. In principle, this would simply change a cache. But since this information is stored in commits rather than a cache, changing it means changing commit hashes (going forward). Some users rely on the convert extension from hg to hg not changing hashes when nothing changes (usually). Allow these users to preserve hashes despite changes to the changelog files computation by reusing these files lists when the manifest is unchanged (since these files list are derived from the manifest).

tests: show the files fields of changelogs for many merges I don't think there's coverage for many of the subtle cases, and I found it hard to understand what the code is doing by reading it. The test takes 40s to run on a laptop, or 9s with --chg. I have yet to find a description of what the files field is supposed to be for merges. I thought it could be one of: 1. the files added/modified/removed relative to p1 (wouldn't seem useful, but `hg diff -c -r mergerev` has this behavior) 2. the files with filelog nodes not in either parent (i.e., what is needed to create a bundle out of a commit) 3. the files added/removed/modified files by merge itself [1] It's clearly not 1, because file contents merges are symmetric. It's clearly not 2 because removed files and exec bit changes are listed. It's also not 3 but I think it's intended to be 3 and the differences are bugs. Assuming 3, the test shows that, for merges, the list of files both overapproximates and underapproximates. All the cases involve file changes not in the filelog but in the manifest (existence of file at revision, exec bit and file vs symlink). I didn't look at all underapproximations, but they looked minor. The two overapproximations are problematic though because they both cause potentially long lists of files when merging cleanly. [1] even what it means for the merge commit itself to change a file is not completely trivial. A file in the merge being the same as in one of the parent is too lax as it would consider that merges change nothing when they revert all the changes done on one side. The criteria used in the test and in the next commit for "merge didn't touch a file" is: - the parents and the merge all have the same file - or, one parent didn't touch the file and the other parent contains the same file as the merge Differential Revision: https://phab.mercurial-scm.org/D6612

phabricator: handle local:commits time being string or int When setting local:commits arcanist has different behaviour depending on whether the repo is git or hg. With hg it sets the time as a number, since it calls PHP's strtotime on the value, but with git it sets it as a string. Normally this wouldn't be an issue since phabread wouldn't be interacting with Phabricator Revisions for git repos, but Mozilla has a secondary workflow for git users that uses the git-cinnabar tool to interact with their hg repos. When a git-cinnabar user uses the moz-phab tool to submit patches for mozilla-central it makes use of Mozilla's fork of arcanist, which works with their local git version of m-c, and thus sets the local:commit time as a string, and then translates the commit hashes. Currently when encountering such DREVS phabread dies with "TypeError: %d format: a number is required, not str". phabsend also used to set it as a string but wouldn't have encountered the issue with its own DREVs since it would read hg:meta first.
