The changeset displayer allows setting extra keywords to be available
to the templating layer. This patch adds an argument to displaygraph()
to pass a dict of extra properties to be available to every changeset.

Following https://phab.mercurial-scm.org/D636, passing the same date that the
changeset to amend would results in no new commits but the output changed
from:
$ hg amend -d '0 0'
nothing changed
[1]
to:
$ hg amend -d '0 0'
Restore the old behavior by parsing the date passed as parameter so the
condition "date == old.date()" correctly works in cases both dates are
identical.
Add a test for covering this regression.
This bug was found thanks to Evolve test suite.

Since the redundant commit during the amend has been been removed, there is no
need for commit callback function in amend now. Therefore, this commit removes
the unused parameter "commmitfunc" which was being used for this purpose.

There was an extra commit made during the amend operation to track the
changes to the working copy. However, this logic was written a long time back
and newer API's make this extra commit redundant. Therefore, I am removing the
extra commit. After this change, I noticed that
- Execution time of the cmdutil.amend improved by over 40%.
- Execution time of "hg commit --amend" improved by over 20%.
Test Plan:
I ensured that the all the hg tests passed after the change. I had
to fix a few tests which were aware of the extra commit made during the amend.

Changes the API of `ui.edit()` to take an optional `action` argument,
which is used when constructing the suffix of the temp file.
Previously, it was possible to set the suffix by specifying a `suffix` to the
optional `extra` dict that was passed to `ui.edit()`, but the goal is to
drop support for `extra.suffix` and make `action` a required argument.
To this end, `ui.edit()` now yields a `develwarn()` if `action` is not set
or if `extra.suffix` is set.
I updated all calls to `ui.edit()` I could find in `hg-crew` to specify the
appropriate `action`. This means that when creating a commit, instead
of the path to the editor file being something like:
`/tmp/hg-editor-XXXXXX.txt`
it is now something like:
`/tmp/hg-editor-XXXXXX.commit.hg.txt`
Some editors (such as Atom) make it possible to statically define a [TextMate]
grammar for files with a particular suffix. For example, because Git reliably
uses `.git/COMMIT_EDITMSG` and `.git/MERGE_MSG` as the paths for commit-type
messages, it is trivial to define a grammar that is applied when files of
either name are opened in Atom:
https://github.com/atom/language-git/blob/v0.19.1/grammars/git%20commit%20message.cson#L4-L5
Because Hg historically used a generic `.txt` suffix, it was much harder to
disambiguate whether a file was an arbitrary text file as opposed to one
created for the specific purpose of authoring an Hg commit message.
This also makes it easier to add special support for `histedit`, as it has its own
suffix that is distinct from a commit:
`/tmp/hg-histedit-XXXXXX.histedit.hg.txt`
Test Plan:
Added an integration test: `test-editor-filename.t`.
Manually tested: ran `hg ci --amend` for this change and saw that it
used `/tmp/hg-editor-ZZjcz0.commit.hg.txt` as the path instead of
`/tmp/hg-editor-ZZjcz0.txt` as the path.
Verified `make tests` passes.

This should be sensible default since mfunc(subset) is roughly equivalent
to 'subset & mfunc'. The order argument is still there so we can specify
'anyorder' if the order doesn't really matter.

Wrapping text in templates for 'hg log --graph' can't be done very well,
because the template doesn't know how wide the graph drawing is. The edge
drawing function needs to know the number of lines in the template output, so
we need to also determine how wide that drawing would be before we call the
edgefn or evaluate the template.
This patch makes edgefn compute the graph width and pass it into the template
so that we can do something like this:
COLUMNS=10 hg log --graph --template "{fill(desc, termwidth - graphwidth)}"
@ a a a a
| a a a a
| a a a a
o a a a
|\ a a a
| | a a a
| | a a a
Using extensions to do this would be relatively complicated due to a lack of
hooks in this area of the code.
In the future it may make sense to have a more generic "textwidth" that tells
you how many columns you can expect to fill without causing the terminal to
wrap your output. I'm not sure there are other situations to motivate this yet,
or if it is entirely feasible.

When I wrote f33f2b5b4874 (commit: don't let failed commit with
--addremove update dirstate (issue5645), 2017-07-31), Durham's
422ca3501516 (rebase: use one dirstateguard for when using
rebase.singletransaction, 2017-07-20) had not yet landed, so I had to
write it in the old-fashioned way. Now that Durham's patch is in, we
can simplify by using a context manager.
Differential Revision: https://phab.mercurial-scm.org/D406
This is just a simple refactoring to make the next patch simpler. If
the dirstateguard constructor raises an exception, the finally-block
won't do anything anyway, so this is functionally equivalent (and
there is no except-block).

morestatus extension in fbext use to show more context about the state of the
repo like the repository is in a unfinished merge state, or a rebase is going
on, or histedit is going on, listing the files which need to be resolved and
also suggesting ways to handle the situation.
This patch moves the extension directly to core by plugging it into the
--verbose flag of the status command. So now if you are in any unfinished state
and you do hg status -v, it will show you details and help related to the state.
The extension in fbext also shows context about unfinished update state
which is not ported to core as that plug in hooks to update command which need
to be tackled somewhat differently.
The following configuration will turn the behaviour on by default
[commands]
status.verbose = 1
You can also skip considering some states like bisect as follows:
[commands]
status.skipstates=bisect
This patch also adds test for the feature.
.. feature::
``hg status -v`` can now show unfinished state. For example, when in
an unfinished rebase state, ``hg status -v`` might show::
# The repository is in an unfinished *rebase* state.
# No unresolved merge conflicts.
# To continue: hg rebase --continue
# To abort: hg rebase --abort

As we changed the meaning of unstable between the old vocabulary and the new

The initial attempt was to discard cache when appropriate, but it appears
to be error prone. We had to carefully inspect all places where audit() is
called e.g. without actually updating filesystem, before removing files and
directories, etc.
So, this patch disables the cache of audited paths by default, and enables
it only for the following cases:
- short-lived auditor objects
- repo.vfs, repo.svfs, and repo.cachevfs, which are managed directories
and considered sort of append-only (a file/directory would never be
replaced with a symlink)
There would be more cacheable vfs objects (e.g. mq.queue.opener), but I
decided not to inspect all of them in this patch. We can make them cached
later.
Benchmark result:
- using old clone of http://selenic.com/repo/linux-2.6/ (38319 files)
- on tmpfs
- run HGRCPATH=/dev/null hg up -q --time tip && hg up -q null
- try 4 times and take the last three results
original:
real 7.480 secs (user 1.140+22.760 sys 0.150+1.690)
real 8.010 secs (user 1.070+22.280 sys 0.170+2.120)

This adds an experimental flag -t/--terse which will terse the output. The terse flag
will respect other flags which filters the output. The flag takes a string
whose value can be a subsequence of "marduic" (the order does not matter here.)
Ignored files are not considered while tersing unless -i flag is passed or 'i'
is there is the terse flag value.
The flag is experimental for testing as there may be cases which will produce
strange results with the flag. We can set the terse on by default by simply
passing 'u' to the cmdutil.tersestatus().
This patch also adds a test file with tests covering the new feature.
We do not touch the bookmarks store in this code, just the active bookmark, not
covered by the transaction. So it seems we can safely drop this call and the
tests agree with us.
Let "isignoreddir" function first check that supplied directory is itself
ignored before walking recursively into its content. Otherwise, the command is
awfully slow when one has an ignored directory with a lot of content.
Update and rephrase function docstring accordingly.
Rename trouble(s) to instability in all external user-facing output. Only
update user-facing output for the moment, variables names, templates keyword
and potentially configuration would be done in later series.
The renaming is done according to
https://www.mercurial-scm.org/wiki/CEDVocabulary.

This is equivalent to the previous code. But it seems to me that if the user is
going to be prompted that a commit is needed, missing files should be ignored,
but branch and merge changes shouldn't be.
Extensions sometimes wants to add other information in the default log output
format (when no templating is used).
Add an empty function named '_exthook' for easing the extension life.
Extensions will be able to wrap this function and collaborate to display
additional information.
Exthook is called after displaying troubles and just before displaying the
files, extra and description.
Add a new test file to test it and not pollute other test files.
As commented, this should be used with docheader and docfooter, not with
header nor footer. That's one reason why no props are passed to templater
when rendering a separator. (See map-cmdline.changelog to understand what
the "header" is.)
Since this postfix hack exists only for backward compatibility, we don't need
it for new [templates] section. This isn't a BC as templates defined in
[templates] section weren't loaded until recently.
