0b425b5f11 txnutil: add HG_SHAREDPENDING and trysharedpending
Summary:
Add `HG_SHAREDPENDING` which contains the path to the shared primary repository,
similar to how `HG_PENDING` contains the path to the local repository.

Repositories that are not shared check whether either of these refer to the
local repository path.  Repositories that are shared check whether the pending
directory matches their own path, or the shared-pending directory matches their
shared path, via the new `trysharedpending` function.

This fixes the asymmetry in shared repos where pending changes made in a shared
repo were not visible in the primary repo, even though they were visible the
other way around.

07f3d004cc summary: remove branch related logic
Summary:
I noticed `hg summary` takes 32 seconds running in my local repo. Profiling
shows 30 seconds spent on `changelog.findmissing`. We don't use branches and
heavily patched other places to get rid of branch heads logic. So let's remove
them from `hg summary` too.

effa0da8de test-helpers: add a helper to run test using chg
Summary:
The helper could be used in individual tests to enable chg if chg exists.
This allows us to have more precise control on what tests to use chg instead
of using a global flag in run-tests.py.

This makes certain tests containing many hg commands much faster. For example,
`test-revset.t` took 99 seconds before:

  % ./run-tests.py test-revset.t --time
  .
  # Ran 1 tests, 0 skipped, 0 failed.
  # Producing time report
  start   end     cuser   csys    real      Test
    0.000  99.990  86.410  12.000  99.990   test-revset.t

And 10 seconds after:

  % ./run-tests.py test-revset.t --time
  .
  # Ran 1 tests, 0 skipped, 0 failed.
  # Producing time report
  start   end     cuser   csys    real      Test
    0.000  10.080   0.380   0.130  10.080   test-revset.t

Also enable it for some other tests. Note the whitelist is not complete.  We
probably want to whitelist more tests in the future.

The feature could be opted out by deleting `contrib/chg/chg`.

9d58e7d4a4 test-largefiles: demonstrate problems with renaming and reverting a directory
These things were uncovered looking at issue5738.

First, if the destination directory exists under .hglf, the source is moved
under the destination instead of renaming the last component for `hg mv srcdir
dstdir`.  This is extra confusing, because it occurs even if the user visible
destination (i.e. the path _not_ under .hglf) does not exist.

Additionally, when a largefile is forgotten via revert, any modifications end up
getting clobbered.  For normal files, the forgotten file is left unchanged, as
shown by test-import.t.  The forget command on a largefile will correctly leave
the file unmodified.

1146ca6217 templatekw: force noprefix=False to insure diffstat consistency (issue4755)
The result of diffstatdata should not depend on having noprefix set or not, as
was reported in issue 4755. Forcing noprefix to false on call makes sure the
parser receives the diff in the correct format and returns the proper result.

Another way to fix this would have been to change the regular expressions in
path.diffstatdata(), but that would have introduced many unecessary special
cases.

8f93d72f88 hook: centralize passing HG_PENDING to external hook process
This patch centralizes passing HG_PENDING to external hook process
into '_exthook()'. To make in-memory changes visible to external hook
process, this patch does:

  - write (or schedule to write) in-memory dirstate changes, and
  - set HG_PENDING environment variable, if:
    - a transaction is running, and
    - there are in-memory changes to be visible

This patch tests some commands with some hooks, because transaction
activity of a same hook differs from each other ("---": "not tested").

    ======== ========= ========= ============
    command  preupdate precommit pretxncommit
    ======== ========= ========= ============
    unshelve   o        ---       ---

    qrefresh   ---       x         o
    ======== ========= ========= ============

Each hooks are examined separately to prevent in-memory changes from
being visible to external process accidentally by side effect of hooks
previously invoked.

36207b46bf cmdutil: make in-memory changes visible to external editor (issue4378)
Before this patch, external editor process for the commit log can't
view some in-memory changes (especially, of dirstate), because they
aren't written out until the end of transaction (or wlock).

This causes unexpected output of Mercurial commands spawned from that
editor process.

To make in-memory changes visible to external editor process, this
patch does:

  - write (or schedule to write) in-memory dirstate changes, and
  - set HG_PENDING environment variable, if:
    - a transaction is running, and
    - there are in-memory changes to be visible

"hg diff" spawned from external editor process for "hg qrefresh"
shows:

  - "changes newly imported into the topmost" before ab68b153ce34(*)
  - "all changes recorded in the topmost by refreshing" after this patch

(*) ab68b153ce34 changed steps invoking editor process

Even though backward compatibility may be broken, the latter behavior
looks reasonable, because "hg diff" spawned from the editor process
consistently shows "what changes new revision records" regardless of
invocation context.

In fact, issue4378 itself should be resolved by b46029eb5b29, which
made 'repo.transaction()' write in-memory dirstate changes out
explicitly before starting transaction. It also made "hg qrefresh"
imply 'dirstate.write()' before external editor invocation in call
chain below.

  - mq.queue.refresh
    - strip.strip
      - repair.strip
        - localrepository.transaction
          - dirstate.write
    - localrepository.commit
      - invoke external editor

Though, this patch has '(issue4378)' in own summary line to indicate
that issues like issue4378 should be fixed by this.

BTW, this patch adds '-m' option to a 'hg ci --amend' execution in
'test-commit-amend.t', to avoid invoking external editor process.

In this case, "unsure" states may be changed to "clean" according to
timestamp or so on. These changes should be written into pending file,
if external editor invocation is required,

Then, writing dirstate changes out breaks stability of test, because
it shows "transaction abort!/rollback completed" occasionally.

Aborting after editor process invocation while commands below may
cause similar instability of tests, too (AFAIK, there is no more such
one, at this revision)

  - commit --amend
    - without --message/--logfile

  - import
    - without --message/--logfile,
    - without --no-commit,
    - without --bypass,
    - one of below, and
      - patch has no description text, or
      - with --edit
    - aborting at the 1st patch, which adds or removes file(s)
      - if it only changes existing files, status is checked only for
        changed files by 'scmutil.matchfiles()', and transition from
        "unsure" to "normal" in dirstate doesn't occur (= dirstate
        isn't changed, and written out)
      - aborting at the 2nd or later patch implies other pending
        changes (e.g. changelog), and always causes showing
        "transaction abort!/rollback completed"

344e42ce00 localrepo: restore dirstate to one before rollbacking if not parent-gone
'localrepository.rollback()' explicilty restores dirstate, only if at
least one of current parents of the working directory is removed at
rollbacking (a.k.a "parent-gone").

After DirstateTransactionPlan, 'dirstate.write()' will cause marking
'.hg/dirstate' as a file to be restored at rollbacking.

    https://mercurial.selenic.com/wiki/DirstateTransactionPlan

Then, 'transaction.rollback()' restores '.hg/dirstate' regardless of
parents of the working directory at that time, and this causes
unexpected dirstate changes if not "parent-gone" (e.g.  "hg update" to
another branch after "hg commit" or so, then "hg rollback").

To avoid such situation, this patch restores dirstate to one before
rollbacking if not "parent-gone".

  before:
    b1. restore dirstate explicitly, if "parent-gone"

  after:
    a1. save dirstate before actual rollbacking via dirstateguard
    a2. restore dirstate via 'transaction.rollback()'
    a3. if "parent-gone"
        - discard backup (a1)
        - restore dirstate from 'undo.dirstate'
    a4. otherwise, restore dirstate from backup (a1)

Even though restoring dirstate at (a3) after (a2) seems redundant,
this patch keeps this existing code path, because:

  - it isn't ensured that 'dirstate.write()' was invoked at least once
    while transaction running

    If not, '.hg/dirstate' isn't restored at (a2).

    In addition to it, rude 3rd party extension invoking
    'dirstate.write()' without 'repo' while transaction running (see
    subsequent patches for detail) may break consistency of a file
    backup-ed by transaction.

  - this patch mainly focuses on changes for DirstateTransactionPlan

    Restoring dirstate at (a3) itself should be cheaper enough than
    rollbacking itself. Redundancy will be removed in next step.

Newly added test is almost meaningless at this point. It will be used
to detect regression while implementing delayed dirstate write out.

7771de9187 summary: add a phase line (draft, secret) to the output
The number of draft and secret changesets are currently not summarized.
This is an important information because the number of drafts give some rough
idea of the number of outgoing changesets in typical workflows, without needing
to probe a remote repository. And a non-zero number of secrets means that
those changeset will not be pushed.

If the repository is "dirty" - some draft or secret changesets exists - then
summary will display a line like:

phases: X draft, Y secret (public)

The phase in parenthesis corresponds to the highest phase of the parents of
the working directory, i.e. the current phase.

By default, the line is not printed if the repository is "clean" - all
changesets are public - but if verbose is activated, it will display:

phases: (public)

On the other hand, nothing will be printed if quiet is in action.

A few tests have been added in test-phases.t to cover the -v and -q cases.

"editform" argument for "getcommiteditor" is decided according to the
format below:

  COMMAND[.ROUTE]

  - COMMAND: name of command
  - ROUTE: name of route, if there are two or more routes in COMMAND

This patch uses "normal.normal" and "normal.merge" as ROUTE of
"editform" instead of "normal", to distinguish merge commits from
other in "hg import" without "--bypass" case.

This patch assumes "editform" variations for "hg import" below:

    import.normal.merge
    import.bypass.normal
    import.bypass.merge

Unlike other patches in this series, this patch uses "editor.sh"
instead of "checkeditform.sh" for the name of the script to check
"HGEDITFORM", because it has to do more than checking "HGEDITFORM".

To invoke editor forcibly in "test-import-merge.t", this patch creates

b7c330c46d import: add --partial flag to create a changeset despite failed hunks
The `hg import` command gains a `--partial` flag. When specified, a commit will
always be created from a patch import. Any hunk that fails to apply will
create .rej file, same as what `hg qimport` would do. This change is mainly
aimed at preserving changeset metadata when applying a patch, something very
important for reviewers.

In case of failure with `--partial`, `hg import` returns 1 and the following
message is displayed:

    patch applied partially
    (fix the .rej files and run `hg commit --amend`)

When multiple patches are imported, we stop at the first one with failed hunks.

In the future, someone may feel brave enough to tackle a --continue flag to
import.

ef317883c7 export: show 'Date' header in a format that also is readable for humans
'export' is the official export format and used by patchbomb, but it would only
show date as a timestamp that most humans might find it hard to relate to. It
would be very convenient when reviewing a patch to be able to see what
timestamp the patch will end up with.

Mercurial has always used util.parsedate for parsing these headers. It can
handle 'all' date formats, so we could just as well use a readable one.

'export' will now use the format used by 'log' - which is the format described
as 'Unix date format' in the templating help. We assume that all parsers of '#
HG changeset patch'es can handle that.

9355854f8a tests: cleanup of tests that got lost in their own nested directories
Some tests ended up in a directory several directories deeper than $TESTTMP,
usually because some 'cd ..' had been forgotten between different test cases.

Add 'cd ..' where they are missing so the tests get back where they started.

87c663dfca test-import: remove unneeded chmod call
As pointed out by Mads, setting the x bit on dummypatch.py is unneeded, because
it is called with 'python ../dummypatch.py'.

9228db24a3 patch: fix segfault against unified diffs which start line is zero
Since f7e538c3b7ba, if a chunk starts with "@@ -0,1", oldstart turns into
a negative value. Because diffhelpers.testhunk() doesn't expect negative bstart,
it bypasses "alen > blen - bstart" condition and segfaults at
"PyList_GET_ITEM(b, i + bstart)".

20e5c736c0 patch: fuzz more aggressively to match patch(1) behaviour
The previous code was assuming a default context of 3 lines. When fuzzing, it
would take this value in account to reduce the amount of removed line from
hunks top or bottom. For instance, if a hunk has only 2 lines of bottom
context, fuzzing with fuzz=1 would do nothing and with fuzz=2 it would remove
one of those lines. A hunk with one line of bottom context could not be fuzzed
at all.  patch(1) has apparently no such restrictions and takes the fuzz level
at face value.

- test-import.t: fuzz/offset changes at the beginning of file are explained by
  the new fuzzing behaviour and match patch(1) ones. Patching locations are
  different but those of my patch(1) do not make a lot of sense right now
  (patched output are the same)

- test-import-bypass.t: more agressive fuzzing makes a patching supposed to
  fail because of context, succeed. Change the diff to avoid this.

- test-mq-merge.t: more agressive fuzzing would allow the merged patch to apply
  with fuzz, but fortunately we disallow this behaviour. The new output is
  kept.

I have not enough experience with patch(1) fuzzing to know whether aligning our
implementation on it is a good or bad idea. Until now, it has been the
implementation reference. For instance, "qpush" tolerates fuzz (test-mq-merge.t
runs the special case of pushing merge revisions where fuzzing is forbidden).

39da9af001 patch: fix fuzzing of hunks without previous lines (issue3264)
When applying hunks such as:

  @@ -2,1 +2,2 @@
   context
  +change

fuzzing would empty the "old" block and make patchfile.apply() traceback.
Instead, we apply the new block at specified location without testing.

The "bottom hunk" test was removed as patch(1) has no problem applying hunk
with no context in the middle of a file.

a7eea871c8 import: handle git renames and --similarity (issue3187)
There is no reason to discard copy sources from the set of files considered by
addremove(). It was done to handle the case where a first patch would create
'a' and a second one would move 'a' to 'b'. If these patches were applied with
--no-commit, 'a' would first be marked as added, then unlinked and dropped from
the dirstate but still passed to addremove(). A better fix is thus to exclude
removed files which ends being dropped from the dirstate instead of removed.

2582d1e3d9 mdiff/patch: fix bad hunk handling for unified diffs with zero context
Prior to this patch "hg diff -U0", i.e., zero lines of context, would
output hunk headers with a start line one greater than what GNU patch
and git output. Guido van Rossum documents the unified diff format[1]
as having a start line value "one lower than one would expect" for
zero length hunks.

Comparing the behaviour of the three systems prior to this patch in
transforming

  c1
  c3

to

  c1
  c2
  c3

- GNU "diff -U0" reports the hunk as "@@ -1,0 +2 @@"
- "git diff -U0" reports the hunk as "@@ -1,0 +2 @@"
- "hg diff -U0" reports the hunk as "@@ -2,0 +2,1 @@"

After this patch, "hg diff -U0" reports "@@ -1,0 +2,1 @@".

Since "hg export --config diff.unified=0" outputs zero-context unified
diffs, "hg import" has also been updated to account for start lines
one less than expected for zero length hunk ranges.
