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.
