In obsmarker we can't store keys and values of more than 255 bytes in metadata. If we try to do so, ProgrammingError is raised. The note flag to amend stores the note in obsmetadata. If a user will try to store a larger note, he will encounter ProgrammingError which is wrong. We must error out early. Thanks to Yuya for warning about this.

fsmonitor can significantly speed up operations on large working directories. But fsmonitor isn't enabled by default, so naive users may not realize there is a potential to make Mercurial faster. This commit introduces a warning to working directory updates when fsmonitor could be used. The following conditions must be met: * Working directory is previously empty * New working directory adds >= N files (currently 50,000) * Running on Linux or MacOS * fsmonitor not enabled * Warning not disabled via config override Because of the empty working directory restriction, most users will only see this warning during `hg clone` (assuming very few users actually do an `hg up null`). The addition of a warning may be considered a BC change. However, clone has printed warnings before. Until recently, Mercurial printed a warning with the server's certificate fingerprint when it wasn't explicitly trusted for example. The warning goes to stderr. So it shouldn't interfere with scripts parsing meaningful output. The OS restriction was on the advice of Facebook engineers, who only feel confident with watchman's stability on the supported platforms. .. feature:: Print warning when fsmonitor isn't being used on a large repository Differential Revision: https://phab.mercurial-scm.org/D894

This patch adds support to rebase to show the changes in node once the rebase is complete. This will be extremely helpful for automation purposes and editors such as Nuclide. The output is a dictionary of predecessor hash as key and a list of successors' hashes. The successors one is a list as there can be many successors for a single predecessor in case of split and it will good to have a generic output format. This patch adds tests for the same. A new file is created for the patch as existing files related to rebase has their own purpose and there will be more formatter support coming for rebase in next cycle. Thanks to Jun for suggesting to use fm.data(). Differential Revision: https://phab.mercurial-scm.org/D1173

Since the ui objects can be created with the 'load' class method, it is possible to lose the exit handlers information from the old ui instance. For example, running 'test-bad-extension.t' leads to this situation where chg creates a new ui instance which does not copy the exit handlers from the earlier ui instance. For exit handlers, which are special cases anyways, it probably makes sense to have a global state of the handlers. This would ensure that the exit handlers registered once are definitely executed at the end of the request. Test Plan: Ran all the tests without '--chg' option. This also fixes the 'test-bad-extension.t' with the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D1166

Splitting at too small gaps might not be worthwhile. With this changeset, we stop considering splitting on too small gaps. The threshold is configurable. We arbitrarily pick 256K as a default value because it seems "okay". Further testing on various repositories and setups will be needed to tune it. The option name is 'experimental.sparse-read.min-gap-size`, and replaces `experimental.sparse-read.min-block-size` which is not used any more.

The previous recursive approach was trying to optimise each read slice to have a good density. It had the tendency to over-optimize smaller slices while leaving larger hole in others. The new approach focuses on improving the combined density of all the reads, instead of the individual slices. It slices at the largest gaps first, as they reduce the total amount of read data the most efficiently. Another benefit of this approach is that we iterate over the delta chain only once, reducing the overhead of slicing long delta chains. On the repository we use for tests, the new approach shows similar or faster performance than the current default linear full read. The repository contains about 450,000 revisions with many concurrent topological branches. Tests have been run on two versions of the repository: one built with the current delta constraint, and the other with an unlimited delta span (using 'experimental.maxdeltachainspan=0') Below are timings for building 1% of all the revision in the manifest log using 'hg perfrevlogrevisions -m'. Times are given in seconds. They include the new couple of follow-up changeset in this series. delta-span standard unlimited linear-read 922s 632s sparse-read 814s 566s

I think there's a slight hole here in that a subrepo could be shared, removed from .hgsub, and then it's not part of context.substate (so not iterated over). But the push command has the same hole IIRC, and I think removing a subrepo is an edge case. The import hack is a copy/paste of subrepo.subrepo().

Matt Harbison authored
This will be used to setup unsharing subrepos. Usually cmdutil is used for this purpose. But the implementation needs hg.copystore(), and the hg module already imports cmdutil.

We add an experimental -L/--line-range option to 'hg log' taking file patterns along with a line range using the (new) FILE,FROMLINE-TOLINE syntax where FILE may be a pattern (matching exactly one file). The resulting history is similar to what the "followlines" revset except that, if --patch is specified, only diff hunks within specified line range are shown. Basically, this brings the CLI on par with what currently only exists in hgweb through line selection in "file" and "annotate" views resulting in a file log with filtered patch to only display followed line range. The option may be specified multiple times and can be combined with --rev and regular file patterns to further restrict revisions. Usage of this option requires --follow; revisions are shown in descending order and renames are followed. Only the --graph option is currently not supported. The UI is the result of a consensus from review feedback at: https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-October/106749.html The implementation spreads between commands.log() and cmdutil module. In commands.log(), the main loop may now use a "hunksfilter" factory (similar to "filematcher") that, for a given "rev", produces a filtering function for diff hunks for a given file context object. The logic to build revisions from -L/--line-range options lives in cmdutil.getloglinerangerevs() which produces "revs", "filematcher" and "hunksfilter" information. Revisions obtained by following files' line range are filtered if they do not match the revset specified by --rev option. If regular FILE arguments are passed along with -L options, both filematchers are combined into a new matcher. .. feature:: Add an experimental -L/--line-range FILE,FROMLINE-TOLINE option to 'hg log' command to follow the history of files by line range. In combination with -p/--patch option, only diff hunks within specified line range will be displayed. Feedback, especially on UX aspects, is welcome.

We add a 'hunksfilterfn' keyword argument in all functions of the call stack from changeset_printer.show() to patch.diff(). This is a callable that will be used to filter out hunks by line range and will be used in the "-L/--line-range" option of "hg log" command introduced in the following changesets.

Use the verbosity aware template keyword introduced earlier. It has the nice property of being verbosity dependent but in order to customize the obsfate part, users will need to replace the lobsfate definition from default mapfile with the one using template functions (by copying the one from test-obsmarker- template.t for example). As it's a more advanced use-case, I'm more inclined to have the same code for the {obsfate} keyword, in the changeset printer and in the default mapfile for consistency. But, the definition in default mapfile could be replaced with one based on template filter to obsfate output customization if it is a big need for users.

Having an obsfate by default in log will be useful for users to understand why they have obsolete and unstable changesets. Obsfate will only be shown for obsolete changesets, which only happens if people opt-in to experimental feature. But when obsolete changeset are visible, it is very useful to understand where they are. Having it in log could be sufficient for most people, so they don't have to learn a new command (like obslog which is itself useful in case of divergences). For example, when pulling and working directory parent become obsolete: $ hg pull ... working directory parent is obsolete! (f936c1697205) This message comes from the Evolve extension. Obsfate would comes handy: $ hg log -G o changeset: 2:6f91013c5136 | tag: tip | parent: 0:4ef7b558f3ec | user: Boris Feld <boris.feld@octobus.net> | date: Mon Oct 09 16:00:27 2017 +0200 | summary: A | | @ changeset: 1:f936c1697205 |/ user: Boris Feld <boris.feld@octobus.net> | date: Mon Oct 09 16:00:27 2017 +0200 | obsfate: rewritten using amend as 2:6f91013c5136 | summary: -A | o changeset: 0:feb4dd822b8c user: Boris Feld <boris.feld@octobus.net> date: Tue Oct 09 16:00:00 2017 +0200 summary: ROOT And once we update, we don't have an obsolete changeset in the log anymore so we don't show obsfate anymore, most users won't see obsfate often if they don't have obsolete changeset often: @ changeset: 2:6f91013c5136 | tag: tip | parent: 0:4ef7b558f3ec | user: Boris Feld <boris.feld@octobus.net> | date: Mon Oct 09 16:00:27 2017 +0200 | summary: A | o changeset: 0:feb4dd822b8c user: Boris Feld <boris.feld@octobus.net> date: Tue Oct 09 16:00:00 2017 +0200 summary: ROOT

Obsolescence is sometimes used only locally so the obs-marker users is always the same. Showing the user in this case does not bring much values. In the case where multiple users rewrite the commit, display the full list of users. Also show all users in verbose mode.
