templatefilters: undeprecate hgdate See the previous patch for why. Backed out changeset 0fe65bb7e160

templater: restore the original string format of {date} Unfortunately, python-hglib relies on that. I could fix python-hglib, but there would be other tools that take a decimal separator as the separator of unixtime and tzoffset. The showfmt is set per instance since new code uses '%d %d' format by default.

hgweb: insist http_status value is a sysstr My previous change was extremely confusing to figure out, because I thought I was looking at a client-side problem. For the low cost of an isinstance assert, we can make those errors not happen in the future. Differential Revision: https://phab.mercurial-scm.org/D3727

hgweb: pass a sysstr to low-level _start_response method This fixes a regression in Python 3 support introduced in 7de7bd407251 on the stable branch. We're so early in do_hgweb that I don't see any especially better choices than this. Differential Revision: https://phab.mercurial-scm.org/D3726

tests: fix printenv script on Python 3 Differential Revision: https://phab.mercurial-scm.org/D3725

cvsps: port changeset __repr__ to py3 This appears to be unused except as a debugging aid, as it didn't break until I added a debug print() in service of the previous fix. Sigh. Differential Revision: https://phab.mercurial-scm.org/D3724

cvsps: avoid comparison between None and a tuple in date sorting Avoids badness on Python 3. I had to figure out which entries in this object *could* be None experimentally, but I think I've got them all now. Differential Revision: https://phab.mercurial-scm.org/D3723

py3: buildbot informs me we have two new passing tests Differential Revision: https://phab.mercurial-scm.org/D3722

tests: fix test-patch.t on pickier /bin/sh implementations This is a graft of 0b39edeff033 and f44306940c94 from default because I'm tired of seeing the FreeBSD build be red on stable. See those revisions for details on what's going on here.

commandserver: close server's fds explicitly from a worker The forked worker does not need to accept connections from the server's socket fd. So let's just close them explicitly to avoid surprises. Differential Revision: https://phab.mercurial-scm.org/D3720

run-tests: restrict the test cases allowed characters Most test cases in core and in extension only use `A-Za-z0-9-` but a few tests in extensions also have a `.` in their test cases names. Also add a `_` to allow all kind of case naming format. Differential Revision: https://phab.mercurial-scm.org/D3721

templater: abstract truth testing to fix {if(list_of_empty_strings)} Non-empty list should always be True even if it's stringified to ''. Spotted by Martin von Zweigbergk.

show: stringify filtered list of tags before testing emptiness `names % "{ifeq(name, 'tip', '', name)}"}"` may return [''], which shouldn't be falsy, but it is thanks to a templater bug. This patch converts [''] to '' before testing truthness.

templatefilters: deprecate hgdate as {date|hgdate} is the default format

templater: make date wrapper support dot/map operations No idea if it will be useful, but it just works.

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. Differential Revision: https://phab.mercurial-scm.org/D3710

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.
