templater: introduce a wrapper for date tuple (BC) Strictly speaking, this is BC, but I believe the original string format (str(float(unixtime)) + str(int(tzoffset))) was just plain wrong.

templater: promote tomap() to an interface type I originally considered merging tomap() with itermaps()/getmember(), but decided to not. We might want to add support for chained map operations (e.g. {foo % func() % ...}), where func() will return a mappable object, and 'foo % func()' will be a mappedgenerator of mappable objects.

templater: rename mappable to hybriditem as it is the primary use case This frees up the name 'mappable' for new interface type.

serve: do not daemonize by default by --print-url Per discussion in D3649, -d/--daemon should be explicitly specified to avoid surprising result. Differential Revision: https://phab.mercurial-scm.org/D3703

mercurial: add .t files to .editorconfig The notable entry here prevents the stripping of trailing whitespace, which is important in .t tests. Differential Revision: https://phab.mercurial-scm.org/D3702

graft: add a new `--stop` flag to stop interrupted graft This patch adds a new flag `--stop` to `hg graft` command which stops the interrupted graft. The `--stop` flag takes back you to the last successful step i.e. it will keep your grafted commits, it will just clear the mergestate and interrupted graft state. The `--stop` is different from `--abort` flag as the latter also undoes all the work done till now which is sometimes not what the user wants. Suppose you grafted a lot of changesets, you encountered conflicts, you resolved them, did `hg graft --continue`, again encountered conflicts, continue, again encountered conflicts. Now you are tired of solving merge conflicts and want to resume this sometimes later. If you use the `--abort` functionality, it will strip your already grafted changesets, making you loose the work you have done resolving merge conflicts. A general goal related to this flag is to add this flag to `rebase` and `histedit` too. The evolve command already has this --stop flag. Tests are added for the new flag. .. feature:: `hg graft` now has a `--stop` flag to stop interrupted graft. Differential Revision: https://phab.mercurial-scm.org/D3668

graft: fix the help text to say `graft reapplies previous options` The options which graft accepts are: * rev * continue * edit * log * force * currentdate * currentuser * date * user * tool * dryrun Out of these following should be reapplied in case conflicts occur and user does `hg graft --continue`: * rev * log * force * currentuser * currentdate * date * user rev and force were already reapplied by --continue. Some recent refactors made graft to store the values of other options in graftstate and reapplies them at `hg graft --continue`. Now all the options which should be reapplied are taken care of, we can easily remove the help note which says that `--continue does not reapply earlier options` and help text saying that we reapplies earlier options. .. feature:: `hg graft --continue` now reapplies all the earlier options `hg graft` now preserves the value of all the flags and reapplies them in case of `hg graft --continue`.

files: drop now-unnecessary filtering of removed dirstate files workingctx.matches() now filters out removed files. Differential Revision: https://phab.mercurial-scm.org/D3712

context: make workingctx.matches() filter our removed files (API) It seems surprising that workingctx.matches() includes files that had been removed in the working copy. The callers don't want that either (besides the `hg locate` that was changed in the previous patch). The only observable difference that I'm aware of is that `hg log -T 'wdir()' -r '{files(...)}'` will no longer include removed files (an improvement, IMO). That matches `hg files` (but does not match the deprecated `hg locate`). Differential Revision: https://phab.mercurial-scm.org/D3711

locate: explicitly use dirstate.matches() for working copy `hg locate` is odd in that it includes files that have been removed from the working copy. It relies on workingctx.matches() for that. I want to make workingctx.matches() not include removed files, so this patch makes `hg locate` handle the working copy differently instead.

revsets: define a none() revset This can be useful for default values in corp-wide configuration (e.g. for commits to hide, which defaults to none()), and perhaps in scripts. I named it none() rather than empty() to match all(). Differential Revision: https://phab.mercurial-scm.org/D3713

statprof: fix save and load Fix these functions even if they don't are used at the moment. Thanks to Yuya Nishihara for spotting that.

perftemplating: abort on incompatible version This is what the other debug commands do. Thanks to Yuya Nishihara for pointing this out.

templater: fix string representation of wrapped None flatten() and stringify() skip None, which means wrappedvalue(None).show() must return '' instead of 'None'. This isn't a problem right now, but we'll encounter it once we start using wrapped types extensively.

templater: show slightly better hint on map operation error It was super hard to find where the templater went wrong if a keyword was evaluated to '' or None.

templater: inline unwraphybrid() flatten() is the solo user of this function.

templater: drop hybrid-ness on unwrapvalue() Proxy methods are no longer necessary as list/dict functions go through the wrapped interface.

templater: mark .keytype as a private attribute

templater: abstract ifcontains() over wrapped types This allows us to make .keytype private. There's a minor BC that a hybrid dict/list of keytype=None now strictly checks the type of the needle. For example, {ifcontains(rev, files)} no longer matches a file named "1" at the rev=1. I made this change for consistency with the get(dict, key) function. We can restore the old behavior by making keytype=bytes the default if desired.

templater: inline wraphybridvalue() All wraphybridvalue() calls are now handled in the hybrid class.

templater: abstract min/max away I'm not certain how many get*() functions I'll add to the wrapped types, but getmin() and getmax() will allow us to optimize a revset wrapper.

stringutil: fix prettyrepr() to not orphan foo=<...> line

debugwalk: pretty-print nested matcher While porting filesets to composition of matchers, I found the original one-liner was hard to read.

debugwalk: show matcher output only if -v/--verbose And drop "egrep -v". This matches the behavior of "hg debugrevspec".

stringutil: promote smartset.prettyformat() to utility function It will be used by debugwalk.

profiling: introduce a "profiling.time-track" option This option allows to switch the time used by the statistical profiler from cpu to real time. Our goal is to profile IO intensive operations using the mercurial profiler.

statprof: also gather wall time Gathering wall time information is useful for operations that are IO (files, network) intensive. For now we only expose it in the final summary.

perftemplating: allow to specify the template to test This is useful to test the evolution of rendering time for a given template.

perftemplating: stop going through the log command Only benchmark the rendering phase by moving steps outside of the timed function: * revisions resolution, * template parsing

perftemplating: move revision argument to flag only The revision we want to render are less important than the templates. We move revision specification behind the usual `--rev` flag.
