tests: add test showing puzzling test output with (glob) lines When using multiple (glob) lines, the test runner often moves the lines around in the output on failure. I have run into this problem many times. The added test shows one example of this. Note that it doesn't show the mismatching lines and instead shows diff hunks that appear to replace a literal by a glob, and other hunks that should clearly match.

tests: move handling of None "el" out of linematch() It just seems odd for linematch() to know what None means. Differential Revision: https://phab.mercurial-scm.org/D3879

tests: remove some redundant code in run-tests These two lines also happen below if "r" is truthy, which it is in this case since it's equal to "retry". Differential Revision: https://phab.mercurial-scm.org/D3878

tests: don't reimplement enumerate() in run-tests Differential Revision: https://phab.mercurial-scm.org/D3877

histedit: improve help text for --no-backup option Improved help text for --no-backup option to clearly define it's meaning. Differential Revision: https://phab.mercurial-scm.org/D3885

histedit: add --no-backup option (issue5825) This option provides a functionality to not store a backup while aborting histedit in between. Also added tests for the same. Differential Revision: https://phab.mercurial-scm.org/D3872

tests: use interfaceutil in simplestorerepo Without it, we crash at module import time. This has likely been busted since 856f381ad74b. Differential Revision: https://phab.mercurial-scm.org/D3884

rebase: improve output of --dry-run Improved output when in dryrun, for user to make sure that no change will be written to repository. Differential Revision: https://phab.mercurial-scm.org/D3764

status: add support for log-like template keywords and functions It's bound to ctx2 since "hg status" can be considered to show the status of the files at ctx2 given ctx1 as the base.

resolve: add support for log-like template keywords and functions It uses wctx as the associated revision since "hg resolve" is the command to manipulate the working directory files.

manifest: add support for log-like template keywords and functions "hg manifest --all" isn't supported since it has no single associated revision.

files: add support for log-like template keywords and functions Note that the ctx does not point to the revision where the file was last changed, but the revision specified by -rREV option.

files: automatically populate fields referenced from template

grep: add support for log-like template keywords and functions

cat: add support for log-like template keywords and functions

bookmarks: add support for log-like template keywords and functions This is basically the same as 5d9b765dbe15 "tags: unblock log-like template keywords and functions."

fix: add progress bar for number of file revisions processed This ensures responsiveness when the configured tools are slow or numerous. Differential Revision: https://phab.mercurial-scm.org/D3848

fix: use a worker pool to parallelize running tools This is important for usability when tools are slow or numerous. Differential Revision: https://phab.mercurial-scm.org/D3846

worker: support more return types in posix worker This allows us to return things that aren't tuple(int, str) from worker functions. I wanted to use marshal instead of pickle, but it seems to read from the pipe in non-blocking mode, which means it stops before it sees the results. The windows worker already supports arbitrary return values without serialization, because it uses threads instead of subprocesses. Differential Revision: https://phab.mercurial-scm.org/D3845

debug: process --debug flag earlier This allow the verbosity level to be set correctly during extension initialization.

test: stop passing --quiet in a run dedicated to debug output The goal of the run is to display some debug output. Passing --quiet in this case is strange.

acl: add bookmarks support Originally submitted at https://www.mercurial-scm.org/pipermail/mercurial-devel/2016-March/080650.html as an RFC by timeless. .. feature:: The `acl` extension now has support for bookmarks as well as branches. Differential Revision: https://phab.mercurial-scm.org/D3750

repository: define manifest interfaces The long march towards declaring interfaces for repository primitives continues. This commit essentially defines interfaces based on the following types: * manifest.manifestdict -> imanifestdict * manifest.manifestlog -> imanifestlog * manifest.memmanifestctx -> imanifestrevisionwritable * manifest.manifestctx -> imanifestrevisionstored * manifest.memtreemanifestctx -> imanifestrevisionwritable * manifest.treemanifestctx -> imanifestrevisionstored * util.dirs -> idirs The interfaces are thoroughly documented. Their documentation is now better than the documentation in manifest.py in many cases. With the exception of util.dirs, classes have been annotated with their interfaces. (I didn't feel like util.dirs needed the proper interface treatment.) Tests have been added demonstrating that all classes and instances conform to their interfaces. This work was much easier than filelogs. That's because Durham did an excellent job formalizing the manifest API a while back. There are still some minor kludges with the interfaces that should probably be addressed. But the primary goal with interface declarations is getting something established. Once we have an interface, we can modify it later easily enough. Differential Revision: https://phab.mercurial-scm.org/D3869

narrowbundle2: when we handle a widen, mark the operation as unsafe We have to manually drive the context manager here since the logic is awkwardly split between a couple of places. Differential Revision: https://phab.mercurial-scm.org/D3719

narrow: mark the critical chunks of narrowing/widening as unsafe I'm _mostly_ sure these are the only unsafe chunks here. Differential Revision: https://phab.mercurial-scm.org/D3718

repair: mark the critical section of strip() as unsafe When our experimental nointerrupt feature is enabled, this will help prevent users from corrupting their repo during a strip. Differential Revision: https://phab.mercurial-scm.org/D3717

ui: add an uninterruptable context manager that can block SIGINT The blocking of SIGINT is not done by default, but my hope is that we will one day. This was inspired by Facebook's "nointerrupt" extension, which is a bit more heavy-handed than this (whole commands are treated as unsafe to interrupt). A future patch will enable this for varying bits of Mercurial that are performing unsafe operations. It's intentional that the KeyboardInterrupt is raised as the context manager exits: during the span of the context manager interrupting Mercurial could lead to data loss, but typically those spans are fairly narrow, so we can let the unsafe block complete and then terminate hg (which will leave the repo in a consistent state, even if it's not the user's desired state). .. api:: New context manager ``ui.uninterruptable()`` to mark portions of a command as potentially unsafe places to interrupt Mercurial with Control-C or similar.

revset: add partial support for ancestor(wdir()) It's easy, so let's make it happen. I'm not certain if 'wdir() &' should be required. ancestors(wdir()) works without it, but ancestor(wdir()) doesn't as of now. That's the issue of fullreposet.__contains__() vs __and__().

context: also accept diff option directly For now we accept both diff option and dictionary. This will let us upgrade internal users gradually before we drop the old API at the end of this series.
