rebase: change and standarize template for rebase's one-line summary

This removes the default template in rebase and switches to a
centrally defined template. I've simplified it a bit to avoid the
conditional parenthesis. I've also added labels so the different parts
can be easily colored. The template is somewhat similar to what we've
used internally at Google for a few years.

I'm happy to change the template if others have opinions. Should we
reuse the `color.log.` names as I have?

 def rebase(ui, repo, **opts):
     """move changeset (and descendants) to a different branch
 
     Rebase uses repeated merging to graft changesets from one part of
     history (the source) onto another (the destination). This can be
     useful for linearizing *local* changes relative to a master
     development tree.
 
     Published commits cannot be rebased (see :hg:`help phases`).
     To copy commits, see :hg:`help graft`.
 
     If you don't specify a destination changeset (``-d/--dest``), rebase
     will use the same logic as :hg:`merge` to pick a destination.  if
     the current branch contains exactly one other head, the other head
     is merged with by default.  Otherwise, an explicit revision with
     which to merge with must be provided.  (destination changeset is not
     modified by rebasing, but new changesets are added as its
     descendants.)
 
     Here are the ways to select changesets:
 
       1. Explicitly select them using ``--rev``.
 
       2. Use ``--source`` to select a root changeset and include all of its
          descendants.
 
       3. Use ``--base`` to select a changeset; rebase will find ancestors
          and their descendants which are not also ancestors of the destination.
 
       4. If you do not specify any of ``--rev``, ``--source``, or ``--base``,
          rebase will use ``--base .`` as above.
 
     If ``--source`` or ``--rev`` is used, special names ``SRC`` and ``ALLSRC``
     can be used in ``--dest``. Destination would be calculated per source
     revision with ``SRC`` substituted by that single source revision and
     ``ALLSRC`` substituted by all source revisions.
 
     Rebase will destroy original changesets unless you use ``--keep``.
     It will also move your bookmarks (even if you do).
 
     Some changesets may be dropped if they do not contribute changes
     (e.g. merges from the destination branch).
 
     Unlike ``merge``, rebase will do nothing if you are at the branch tip of
     a named branch with two heads. You will need to explicitly specify source
     and/or destination.
 
     If you need to use a tool to automate merge/conflict decisions, you
     can specify one with ``--tool``, see :hg:`help merge-tools`.
     As a caveat: the tool will not be used to mediate when a file was
     deleted, there is no hook presently available for this.
 
     If a rebase is interrupted to manually resolve a conflict, it can be
     continued with --continue/-c, aborted with --abort/-a, or stopped with
     --stop.
 
     .. container:: verbose
 
       Examples:
 
       - move "local changes" (current commit back to branching point)
         to the current branch tip after a pull::
 
           hg rebase
 
       - move a single changeset to the stable branch::
 
           hg rebase -r 5f493448 -d stable
 
       - splice a commit and all its descendants onto another part of history::
 
           hg rebase --source c0c3 --dest 4cf9
 
       - rebase everything on a branch marked by a bookmark onto the
         default branch::
 
           hg rebase --base myfeature --dest default
 
       - collapse a sequence of changes into a single commit::
 
           hg rebase --collapse -r 1520:1525 -d .
 
       - move a named branch while preserving its name::
 
           hg rebase -r "branch(featureX)" -d 1.3 --keepbranches
 
       - stabilize orphaned changesets so history looks linear::
 
           hg rebase -r 'orphan()-obsolete()'\
  -d 'first(max((successors(max(roots(ALLSRC) & ::SRC)^)-obsolete())::) +\
  max(::((roots(ALLSRC) & ::SRC)^)-obsolete()))'
 
     Configuration Options:
 
     You can make rebase require a destination if you set the following config
     option::
 
       [commands]
       rebase.requiredest = True
 
     By default, rebase will close the transaction after each commit. For
     performance purposes, you can configure rebase to use a single transaction
     across the entire rebase. WARNING: This setting introduces a significant
     risk of losing the work you've done in a rebase if the rebase aborts
     unexpectedly::
 
       [rebase]
       singletransaction = True
 
     By default, rebase writes to the working copy, but you can configure it to
     run in-memory for better performance. When the rebase is not moving the
     parent(s) of the working copy (AKA the "currently checked out changesets"),
     this may also allow it to run even if the working copy is dirty::
 
       [rebase]
       experimental.inmemory = True
 
     Return Values:
 
     Returns 0 on success, 1 if nothing to rebase or there are
     unresolved conflicts.

     Args:
       repo: The repository from which we're exporting revisions.
       revs: A list of revisions to export as revision numbers.
       basefm: A formatter to which patches should be written.
       fntemplate: An optional string to use for generating patch file names.
       switch_parent: If True, show diffs against second parent when not nullid.
                      Default is false, which always shows diff against p1.
       opts: diff options to use for generating the patch.
       match: If specified, only export changes to files matching this matcher.
 
     Returns:
       Nothing.
 
     Side Effect:
       "HG Changeset Patch" data is emitted to one of the following
       destinations:
         fntemplate specified: Each rev is written to a unique file named using
                             the given template.
         Otherwise: All revs will be written to basefm.

 Copy a file onto another file with same content. If metadata is stored in changeset, this does not
 produce a new filelog entry. The changeset's "files" entry should still list the file.

 Copy x to z, then remove z, then copy x2 (same content as x) to z. With copy metadata in the
 changeset, the two copies here will have the same filelog entry, so ctx['z'].introrev() might point
 to the first commit that added the file. We should still report the copy as being from x2.

       Runs any configured tools to fix the content of files. Only affects files
       with changes, unless file arguments are provided. Only affects changed
       lines of files, unless the --whole flag is used. Some tools may always
       affect the whole file regardless of --whole.
   
       If --working-dir is used, files with uncommitted changes in the working
       copy will be fixed. Note that no backup are made.
   
       If revisions are specified with --source, those revisions and their
       descendants will be checked, and they may be replaced with new revisions
       that have fixed file content. By automatically including the descendants,
       no merging, rebasing, or evolution will be required. If an ancestor of the
       working copy is included, then the working copy itself will also be fixed,
       and the working copy will be updated to the fixed parent.
   
       When determining what lines of each file to fix at each revision, the
       whole set of revisions being fixed is considered, so that fixes to earlier
       revisions are not forgotten in later ones. The --base flag can be used to
       override this default behavior, though it is not usually desirable to do
       so.
   
   (use 'hg help -e fix' to show help for the fix extension)
   
   options ([+] can be repeated):
   
       --all            fix all non-public non-obsolete revisions
       --base REV [+]   revisions to diff against (overrides automatic selection,
                        and applies to every revision being fixed)
    -s --source REV [+] fix the specified revisions and their descendants
    -w --working-dir    fix the working directory
       --whole          always fix every line of a file
   
   (some details hidden, use --verbose to show complete help)
 
   $ hg help -e fix
   fix extension - rewrite file content in changesets or working copy
   (EXPERIMENTAL)
   
   Provides a command that runs configured tools on the contents of modified
   files, writing back any fixes to the working copy or replacing changesets.
   
   Here is an example configuration that causes 'hg fix' to apply automatic
   formatting fixes to modified lines in C++ code:
   
     [fix]
     clang-format:command=clang-format --assume-filename={rootpath}
     clang-format:linerange=--lines={first}:{last}
     clang-format:pattern=set:**.cpp or **.hpp
   
   The :command suboption forms the first part of the shell command that will be
   used to fix a file. The content of the file is passed on standard input, and
   the fixed file content is expected on standard output. Any output on standard
   error will be displayed as a warning. If the exit status is not zero, the file
   will not be affected. A placeholder warning is displayed if there is a non-
   zero exit status but no standard error output. Some values may be substituted
   into the command:
   
     {rootpath}  The path of the file being fixed, relative to the repo root
     {basename}  The name of the file being fixed, without the directory path
   
   If the :linerange suboption is set, the tool will only be run if there are
   changed lines in a file. The value of this suboption is appended to the shell
   command once for every range of changed lines in the file. Some values may be
   substituted into the command:
   
     {first}   The 1-based line number of the first line in the modified range
     {last}    The 1-based line number of the last line in the modified range
   
   Deleted sections of a file will be ignored by :linerange, because there is no
   corresponding line range in the version being fixed.
   
   By default, tools that set :linerange will only be executed if there is at
   least one changed line range. This is meant to prevent accidents like running
   a code formatter in such a way that it unexpectedly reformats the whole file.
   If such a tool needs to operate on unchanged files, it should set the
   :skipclean suboption to false.
   
   The :pattern suboption determines which files will be passed through each
   configured tool. See 'hg help patterns' for possible values. However, all
   patterns are relative to the repo root, even if that text says they are
   relative to the current working directory. If there are file arguments to 'hg
   fix', the intersection of these patterns is used.
   
   There is also a configurable limit for the maximum size of file that will be
   processed by 'hg fix':
   
     [fix]
     maxfilesize = 2MB
   
   Normally, execution of configured tools will continue after a failure
   (indicated by a non-zero exit status). It can also be configured to abort
   after the first such failure, so that no files will be affected if any tool
   fails. This abort will also cause 'hg fix' to exit with a non-zero status:
   
     [fix]
     failure = abort
   
   When multiple tools are configured to affect a file, they execute in an order
   defined by the :priority suboption. The priority suboption has a default value
   of zero for each tool. Tools are executed in order of descending priority. The
   execution order of tools with equal priority is unspecified. For example, you
   could use the 'sort' and 'head' utilities to keep only the 10 smallest numbers
   in a text file by ensuring that 'sort' runs before 'head':
   
     [fix]
     sort:command = sort -n
     head:command = head -n 10
     sort:pattern = numbers.txt
     head:pattern = numbers.txt
     sort:priority = 2
     head:priority = 1
   
   To account for changes made by each tool, the line numbers used for
   incremental formatting are recomputed before executing the next tool. So, each
   tool may see different values for the arguments added by the :linerange
   suboption.
   
   Each fixer tool is allowed to return some metadata in addition to the fixed
   file content. The metadata must be placed before the file content on stdout,
   separated from the file content by a zero byte. The metadata is parsed as a
   JSON value (so, it should be UTF-8 encoded and contain no zero bytes). A fixer
   tool is expected to produce this metadata encoding if and only if the
   :metadata suboption is true:
   
     [fix]
     tool:command = tool --prepend-json-metadata
     tool:metadata = true
   
   The metadata values are passed to hooks, which can be used to print summaries
   or perform other post-fixing work. The supported hooks are:
   
     "postfixfile"
       Run once for each file in each revision where any fixer tools made changes
       to the file content. Provides "$HG_REV" and "$HG_PATH" to identify the file,
       and "$HG_METADATA" with a map of fixer names to metadata values from fixer
       tools that affected the file. Fixer tools that didn't affect the file have a
       value of None. Only fixer tools that executed are present in the metadata.
   
     "postfix"
       Run once after all files and revisions have been handled. Provides
       "$HG_REPLACEMENTS" with information about what revisions were created and
       made obsolete. Provides a boolean "$HG_WDIRWRITTEN" to indicate whether any
       files in the working copy were updated. Provides a list "$HG_METADATA"
       mapping fixer tool names to lists of metadata values returned from
       executions that modified a file. This aggregates the same metadata
       previously passed to the "postfixfile" hook.
   
   Fixer tools are run in the repository's root directory. This allows them to
   read configuration files from the working copy, or even write to the working
   copy. The working copy is not updated to match the revision being fixed. In
   fact, several revisions may be fixed in parallel. Writes to the working copy
   are not amended into the revision being fixed; fixer tools should always write
   fixed file content back to stdout as documented above.
   
   list of commands:
   
    fix           rewrite file content in changesets or working directory
   
   (use 'hg help -v -e fix' to show built-in aliases and global options)
 
 There is no default behavior in the absence of --rev and --working-dir.
 
   $ hg init badusage
   $ cd badusage
 
   $ hg fix
   abort: no changesets specified
   (use --rev or --working-dir)
   [255]
   $ hg fix --whole
   abort: no changesets specified
   (use --rev or --working-dir)
   [255]
   $ hg fix --base 0
   abort: no changesets specified
   (use --rev or --working-dir)
   [255]
 
 Fixing a public revision isn't allowed. It should abort early enough that
 nothing happens, even to the working directory.
 
   $ printf "hello\n" > hello.whole
   $ hg commit -Aqm "hello"
   $ hg phase -r 0 --public
   $ hg fix -r 0
   abort: cannot fix public changesets
   (see 'hg help phases' for details)
   [255]
   $ hg fix -r 0 --working-dir
   abort: cannot fix public changesets
   (see 'hg help phases' for details)
   [255]
   $ hg cat -r tip hello.whole
   hello
   $ cat hello.whole
   hello
 
   $ cd ..
 
 Fixing a clean working directory should do nothing. Even the --whole flag
 shouldn't cause any clean files to be fixed. Specifying a clean file explicitly
 should only fix it if the fixer always fixes the whole file. The combination of
 an explicit filename and --whole should format the entire file regardless.
 
   $ hg init fixcleanwdir
   $ cd fixcleanwdir
 
   $ printf "hello\n" > hello.changed
   $ printf "world\n" > hello.whole
   $ hg commit -Aqm "foo"
   $ hg fix --working-dir
   $ hg diff
   $ hg fix --working-dir --whole
   $ hg diff
   $ hg fix --working-dir *
   $ cat *
   hello
   WORLD
   $ hg revert --all --no-backup
   reverting hello.whole
   $ hg fix --working-dir * --whole
   $ cat *
   HELLO
   WORLD
 
 The same ideas apply to fixing a revision, so we create a revision that doesn't
 modify either of the files in question and try fixing it. This also tests that
 we ignore a file that doesn't match any configured fixer.
 
   $ hg revert --all --no-backup
   reverting hello.changed
   reverting hello.whole
   $ printf "unimportant\n" > some.file
   $ hg commit -Aqm "some other file"
 
   $ hg fix -r .
   $ hg cat -r tip *
   hello
   world
   unimportant
   $ hg fix -r . --whole
   $ hg cat -r tip *
   hello
   world
   unimportant
   $ hg fix -r . *
   $ hg cat -r tip *
   hello
   WORLD
   unimportant
   $ hg fix -r . * --whole --config experimental.evolution.allowdivergence=true
   2 new content-divergent changesets
   $ hg cat -r tip *
   HELLO
   WORLD
   unimportant
 
   $ cd ..
 
 Fixing the working directory should still work if there are no revisions.
 
   $ hg init norevisions
   $ cd norevisions
 
   $ printf "something\n" > something.whole
   $ hg add
   adding something.whole
   $ hg fix --working-dir
   $ cat something.whole
   SOMETHING
 
   $ cd ..
 
 Test the effect of fixing the working directory for each possible status, with
 and without providing explicit file arguments.
 
   $ hg init implicitlyfixstatus
   $ cd implicitlyfixstatus
 
   $ printf "modified\n" > modified.whole
   $ printf "removed\n" > removed.whole
   $ printf "deleted\n" > deleted.whole
   $ printf "clean\n" > clean.whole
   $ printf "ignored.whole" > .hgignore
   $ hg commit -Aqm "stuff"
 
   $ printf "modified!!!\n" > modified.whole
   $ printf "unknown\n" > unknown.whole
   $ printf "ignored\n" > ignored.whole
   $ printf "added\n" > added.whole
   $ hg add added.whole
   $ hg remove removed.whole
   $ rm deleted.whole
 
   $ hg status --all
   M modified.whole
   A added.whole
   R removed.whole
   ! deleted.whole
   ? unknown.whole
   I ignored.whole
   C .hgignore
   C clean.whole
 
   $ hg fix --working-dir
 
   $ hg status --all
   M modified.whole
   A added.whole
   R removed.whole
   ! deleted.whole
   ? unknown.whole
   I ignored.whole
   C .hgignore
   C clean.whole
 
   $ cat *.whole
   ADDED
   clean
   ignored
   MODIFIED!!!
   unknown
 
   $ printf "modified!!!\n" > modified.whole
   $ printf "added\n" > added.whole
 
 Listing the files explicitly causes untracked files to also be fixed, but
 ignored files are still unaffected.
 
   $ hg fix --working-dir *.whole
 
   $ hg status --all
   M clean.whole
   M modified.whole
   A added.whole
   R removed.whole
   ! deleted.whole
   ? unknown.whole
   I ignored.whole
   C .hgignore
 
   $ cat *.whole
   ADDED
   CLEAN
   ignored
   MODIFIED!!!
   UNKNOWN
 
   $ cd ..
 
 Test that incremental fixing works on files with additions, deletions, and
 changes in multiple line ranges. Note that deletions do not generally cause
 neighboring lines to be fixed, so we don't return a line range for purely
 deleted sections. In the future we should support a :deletion config that
 allows fixers to know where deletions are located.
 
   $ hg init incrementalfixedlines
   $ cd incrementalfixedlines
 
   $ printf "a\nb\nc\nd\ne\nf\ng\n" > foo.txt
   $ hg commit -Aqm "foo"
   $ printf "zz\na\nc\ndd\nee\nff\nf\ngg\n" > foo.txt
 
   $ hg --config "fix.fail:command=echo" \
   >    --config "fix.fail:linerange={first}:{last}" \
   >    --config "fix.fail:pattern=foo.txt" \
   >    fix --working-dir
   $ cat foo.txt
   1:1 4:6 8:8
 
   $ cd ..
 
 Test that --whole fixes all lines regardless of the diffs present.
 
   $ hg init wholeignoresdiffs
   $ cd wholeignoresdiffs
 
   $ printf "a\nb\nc\nd\ne\nf\ng\n" > foo.changed
   $ hg commit -Aqm "foo"
   $ printf "zz\na\nc\ndd\nee\nff\nf\ngg\n" > foo.changed
 
   $ hg fix --working-dir
   $ cat foo.changed
   ZZ
   a
   c
   DD
   EE
   FF
   f
   GG
 
   $ hg fix --working-dir --whole
   $ cat foo.changed
   ZZ
   A
   C
   DD
   EE
   FF
   F

   $ cd ..
 
 We should do nothing with symlinks, and their targets should be unaffected. Any
 other behavior would be more complicated to implement and harder to document.
 
 #if symlink
   $ hg init dontmesswithsymlinks
   $ cd dontmesswithsymlinks
 
   $ printf "hello\n" > hello.whole
   $ ln -s hello.whole hellolink
   $ hg add
   adding hello.whole
   adding hellolink
   $ hg fix --working-dir hellolink
   $ hg status
   A hello.whole
   A hellolink
 
   $ cd ..
 #endif
 
 We should allow fixers to run on binary files, even though this doesn't sound
 like a common use case. There's not much benefit to disallowing it, and users
 can add "and not binary()" to their filesets if needed. The Mercurial
 philosophy is generally to not handle binary files specially anyway.
 
   $ hg init cantouchbinaryfiles
   $ cd cantouchbinaryfiles
 
   $ printf "hello\0\n" > hello.whole
   $ hg add
   adding hello.whole
   $ hg fix --working-dir 'set:binary()'
   $ cat hello.whole
   HELLO\x00 (esc)
 
   $ cd ..
 
 We have a config for the maximum size of file we will attempt to fix. This can
 be helpful to avoid running unsuspecting fixer tools on huge inputs, which
 could happen by accident without a well considered configuration. A more
 precise configuration could use the size() fileset function if one global limit
 is undesired.
 
   $ hg init maxfilesize
   $ cd maxfilesize
 
   $ printf "this file is huge\n" > hello.whole
   $ hg add
   adding hello.whole
   $ hg --config fix.maxfilesize=10 fix --working-dir
   ignoring file larger than 10 bytes: hello.whole
   $ cat hello.whole
   this file is huge
 
   $ cd ..
 
 If we specify a file to fix, other files should be left alone, even if they
 have changes.
 
   $ hg init fixonlywhatitellyouto
   $ cd fixonlywhatitellyouto
 
   $ printf "fix me!\n" > fixme.whole
   $ printf "not me.\n" > notme.whole
   $ hg add
   adding fixme.whole
   adding notme.whole
   $ hg fix --working-dir fixme.whole
   $ cat *.whole
   FIX ME!
   not me.
 
   $ cd ..
 
 If we try to fix a missing file, we still fix other files.
 
   $ hg init fixmissingfile
   $ cd fixmissingfile
 
   $ printf "fix me!\n" > foo.whole
   $ hg add
   adding foo.whole
   $ hg fix --working-dir foo.whole bar.whole
   bar.whole: $ENOENT$
   $ cat *.whole
   FIX ME!
 
   $ cd ..
 
 Specifying a directory name should fix all its files and subdirectories.
 
   $ hg init fixdirectory
   $ cd fixdirectory
 
   $ mkdir -p dir1/dir2
   $ printf "foo\n" > foo.whole
   $ printf "bar\n" > dir1/bar.whole
   $ printf "baz\n" > dir1/dir2/baz.whole
   $ hg add
   adding dir1/bar.whole
   adding dir1/dir2/baz.whole
   adding foo.whole
   $ hg fix --working-dir dir1
   $ cat foo.whole dir1/bar.whole dir1/dir2/baz.whole
   foo
   BAR
   BAZ
 
   $ cd ..
 
 Fixing a file in the working directory that needs no fixes should not actually
 write back to the file, so for example the mtime shouldn't change.
 
   $ hg init donttouchunfixedfiles
   $ cd donttouchunfixedfiles
 
   $ printf "NO FIX NEEDED\n" > foo.whole
   $ hg add
   adding foo.whole
   $ cp -p foo.whole foo.whole.orig
   $ cp -p foo.whole.orig foo.whole
   $ sleep 2 # mtime has a resolution of one or two seconds.
   $ hg fix --working-dir
   $ f foo.whole.orig --newer foo.whole
   foo.whole.orig: newer than foo.whole
 
   $ cd ..
 
 When a fixer prints to stderr, we don't assume that it has failed. We show the
 error messages to the user, and we still let the fixer affect the file it was
 fixing if its exit code is zero. Some code formatters might emit error messages
 on stderr and nothing on stdout, which would cause us the clear the file,
 except that they also exit with a non-zero code. We show the user which fixer
 emitted the stderr, and which revision, but we assume that the fixer will print
 the filename if it is relevant (since the issue may be non-specific). There is
 also a config to abort (without affecting any files whatsoever) if we see any
 tool with a non-zero exit status.
 
   $ hg init showstderr
   $ cd showstderr
 
   $ printf "hello\n" > hello.txt
   $ hg add
   adding hello.txt
   $ cat > $TESTTMP/work.sh <<'EOF'
   > printf 'HELLO\n'
   > printf "$@: some\nerror that didn't stop the tool" >&2
   > exit 0 # success despite the stderr output
   > EOF
   $ hg --config "fix.work:command=sh $TESTTMP/work.sh {rootpath}" \
   >    --config "fix.work:pattern=hello.txt" \
   >    fix --working-dir
   [wdir] work: hello.txt: some
   [wdir] work: error that didn't stop the tool
   $ cat hello.txt
   HELLO
 
   $ printf "goodbye\n" > hello.txt
   $ printf "foo\n" > foo.whole
   $ hg add
   adding foo.whole
   $ cat > $TESTTMP/fail.sh <<'EOF'
   > printf 'GOODBYE\n'
   > printf "$@: some\nerror that did stop the tool\n" >&2
   > exit 42 # success despite the stdout output
   > EOF
   $ hg --config "fix.fail:command=sh $TESTTMP/fail.sh {rootpath}" \
   >    --config "fix.fail:pattern=hello.txt" \
   >    --config "fix.failure=abort" \
   >    fix --working-dir
   [wdir] fail: hello.txt: some
   [wdir] fail: error that did stop the tool
   abort: no fixes will be applied
   (use --config fix.failure=continue to apply any successful fixes anyway)
   [255]
   $ cat hello.txt
   goodbye
   $ cat foo.whole
   foo
 
   $ hg --config "fix.fail:command=sh $TESTTMP/fail.sh {rootpath}" \
   >    --config "fix.fail:pattern=hello.txt" \
   >    fix --working-dir
   [wdir] fail: hello.txt: some
   [wdir] fail: error that did stop the tool
   $ cat hello.txt

   $ cat foo.whole
   FOO
 
   $ hg --config "fix.fail:command=exit 42" \
   >    --config "fix.fail:pattern=hello.txt" \
   >    fix --working-dir
   [wdir] fail: exited with status 42
 
   $ cd ..
 
 Fixing the working directory and its parent revision at the same time should
 check out the replacement revision for the parent. This prevents any new
 uncommitted changes from appearing. We test this for a clean working directory
 and a dirty one. In both cases, all lines/files changed since the grandparent
 will be fixed. The grandparent is the "baserev" for both the parent and the
 working copy.
 
   $ hg init fixdotandcleanwdir
   $ cd fixdotandcleanwdir
 
   $ printf "hello\n" > hello.whole
   $ printf "world\n" > world.whole
   $ hg commit -Aqm "the parent commit"
 
   $ hg parents --template '{rev} {desc}\n'
   0 the parent commit
   $ hg fix --working-dir -r .
   $ hg parents --template '{rev} {desc}\n'
   1 the parent commit
   $ hg cat -r . *.whole
   HELLO
   WORLD
   $ cat *.whole
   HELLO
   WORLD
   $ hg status
 
   $ cd ..
 
 Same test with a dirty working copy.
 
   $ hg init fixdotanddirtywdir
   $ cd fixdotanddirtywdir
 
   $ printf "hello\n" > hello.whole
   $ printf "world\n" > world.whole
   $ hg commit -Aqm "the parent commit"
 
   $ printf "hello,\n" > hello.whole
   $ printf "world!\n" > world.whole
 
   $ hg parents --template '{rev} {desc}\n'
   0 the parent commit
   $ hg fix --working-dir -r .
   $ hg parents --template '{rev} {desc}\n'
   1 the parent commit
   $ hg cat -r . *.whole
   HELLO

   $ cat *.whole
   HELLO,
   WORLD!
   $ hg status
   M hello.whole
   M world.whole
 
   $ cd ..
 
 When we have a chain of commits that change mutually exclusive lines of code,
 we should be able to do incremental fixing that causes each commit in the chain
 to include fixes made to the previous commits. This prevents children from
 backing out the fixes made in their parents. A dirty working directory is
 conceptually similar to another commit in the chain.
 
   $ hg init incrementallyfixchain
   $ cd incrementallyfixchain
 
   $ cat > file.changed <<EOF
   > first
   > second
   > third
   > fourth
   > fifth
   > EOF
   $ hg commit -Aqm "the common ancestor (the baserev)"
   $ cat > file.changed <<EOF
   > first (changed)
   > second
   > third
   > fourth
   > fifth
   > EOF
   $ hg commit -Aqm "the first commit to fix"
   $ cat > file.changed <<EOF
   > first (changed)
   > second
   > third (changed)
   > fourth
   > fifth
   > EOF
   $ hg commit -Aqm "the second commit to fix"
   $ cat > file.changed <<EOF
   > first (changed)
   > second
   > third (changed)
   > fourth
   > fifth (changed)
   > EOF
 
   $ hg fix -r . -r '.^' --working-dir

 If we incrementally fix a merge commit, we should fix any lines that changed
 versus either parent. You could imagine only fixing the intersection or some
 other subset, but this is necessary if either parent is being fixed. It
 prevents us from forgetting fixes made in either parent.
 
   $ hg init incrementallyfixmergecommit
   $ cd incrementallyfixmergecommit
 
   $ printf "a\nb\nc\n" > file.changed
   $ hg commit -Aqm "ancestor"
 
   $ printf "aa\nb\nc\n" > file.changed
   $ hg commit -m "change a"
 
   $ hg checkout '.^'
   1 files updated, 0 files merged, 0 files removed, 0 files unresolved
   $ printf "a\nb\ncc\n" > file.changed

 Abort fixing revisions if there is an unfinished operation. We don't want to
 make things worse by editing files or stripping/obsoleting things. Also abort
 fixing the working directory if there are unresolved merge conflicts.
 
   $ hg init abortunresolved
   $ cd abortunresolved
 
   $ echo "foo1" > foo.whole
   $ hg commit -Aqm "foo 1"
 
   $ hg update null

 When fixing a file that was renamed, we should diff against the source of the
 rename for incremental fixing and we should correctly reproduce the rename in
 the replacement revision.
 
   $ hg init fixrenamecommit
   $ cd fixrenamecommit
 
   $ printf "a\nb\nc\n" > source.changed
   $ hg commit -Aqm "source revision"
   $ hg move source.changed dest.changed
   $ printf "a\nb\ncc\n" > dest.changed
   $ hg commit -m "dest revision"
 
   $ hg fix -r .
   $ hg log -r tip --copies --template "{file_copies}\n"
   dest.changed (source.changed)
   $ hg cat -r tip dest.changed
   a
   b
   CC
 
   $ cd ..
 
 When fixing revisions that remove files we must ensure that the replacement
 actually removes the file, whereas it could accidentally leave it unchanged or
 write an empty string to it.
 
   $ hg init fixremovedfile
   $ cd fixremovedfile
 
   $ printf "foo\n" > foo.whole
   $ printf "bar\n" > bar.whole
   $ hg commit -Aqm "add files"
   $ hg remove bar.whole
   $ hg commit -m "remove file"
   $ hg status --change .
   R bar.whole
   $ hg fix -r . foo.whole
   $ hg status --change tip
   M foo.whole
   R bar.whole
 
   $ cd ..
 
 If fixing a revision finds no fixes to make, no replacement revision should be
 created.
 
   $ hg init nofixesneeded
   $ cd nofixesneeded
 
   $ printf "FOO\n" > foo.whole
   $ hg commit -Aqm "add file"
   $ hg log --template '{rev}\n'
   0
   $ hg fix -r .
   $ hg log --template '{rev}\n'
   0
 
   $ cd ..
 
 If fixing a commit reverts all the changes in the commit, we replace it with a
 commit that changes no files.
 
   $ hg init nochangesleft
   $ cd nochangesleft
 
   $ printf "FOO\n" > foo.whole
   $ hg commit -Aqm "add file"
   $ printf "foo\n" > foo.whole
   $ hg commit -m "edit file"
   $ hg status --change .
   M foo.whole
   $ hg fix -r .
   $ hg status --change tip
 
   $ cd ..
 
 If we fix a parent and child revision together, the child revision must be
 replaced if the parent is replaced, even if the diffs of the child needed no
 fixes. However, we're free to not replace revisions that need no fixes and have
 no ancestors that are replaced.
 
   $ hg init mustreplacechild
   $ cd mustreplacechild
 
   $ printf "FOO\n" > foo.whole
   $ hg commit -Aqm "add foo"
   $ printf "foo\n" > foo.whole
   $ hg commit -m "edit foo"
   $ printf "BAR\n" > bar.whole
   $ hg commit -Aqm "add bar"
 
   $ hg log --graph --template '{rev} {files}'
   @  2 bar.whole
   |
   o  1 foo.whole
   |
   o  0 foo.whole
   
   $ hg fix -r 0:2
   $ hg log --graph --template '{rev} {files}'
   o  4 bar.whole
   |
   o  3
   |
   | @  2 bar.whole
   | |
   | x  1 foo.whole
   |/
   o  0 foo.whole
   
 
   $ cd ..
 
 It's also possible that the child needs absolutely no changes, but we still
 need to replace it to update its parent. If we skipped replacing the child
 because it had no file content changes, it would become an orphan for no good
 reason.
 
   $ hg init mustreplacechildevenifnop
   $ cd mustreplacechildevenifnop
 
   $ printf "Foo\n" > foo.whole
   $ hg commit -Aqm "add a bad foo"
   $ printf "FOO\n" > foo.whole
   $ hg commit -m "add a good foo"
   $ hg fix -r . -r '.^'
   $ hg log --graph --template '{rev} {desc}'
   o  3 add a good foo
   |
   o  2 add a bad foo
   
   @  1 add a good foo
   |
   x  0 add a bad foo
   
 
   $ cd ..
 
 Similar to the case above, the child revision may become empty as a result of
 fixing its parent. We should still create an empty replacement child.
 TODO: determine how this should interact with ui.allowemptycommit given that
 the empty replacement could have children.
 
   $ hg init mustreplacechildevenifempty
   $ cd mustreplacechildevenifempty
 
   $ printf "foo\n" > foo.whole
   $ hg commit -Aqm "add foo"
   $ printf "Foo\n" > foo.whole
   $ hg commit -m "edit foo"
   $ hg fix -r . -r '.^'
   $ hg log --graph --template '{rev} {desc}\n' --stat
   o  3 edit foo
   |
   o  2 add foo
       foo.whole |  1 +
       1 files changed, 1 insertions(+), 0 deletions(-)
   
   @  1 edit foo
   |   foo.whole |  2 +-
   |   1 files changed, 1 insertions(+), 1 deletions(-)
   |
   x  0 add foo
       foo.whole |  1 +
       1 files changed, 1 insertions(+), 0 deletions(-)
   
 
   $ cd ..
 
 Fixing a secret commit should replace it with another secret commit.
 
   $ hg init fixsecretcommit
   $ cd fixsecretcommit
 
   $ printf "foo\n" > foo.whole
   $ hg commit -Aqm "add foo" --secret
   $ hg fix -r .
   $ hg log --template '{rev} {phase}\n'
   1 secret
   0 secret
 
   $ cd ..
 
 We should also preserve phase when fixing a draft commit while the user has
 their default set to secret.
 
   $ hg init respectphasesnewcommit
   $ cd respectphasesnewcommit
 
   $ printf "foo\n" > foo.whole
   $ hg commit -Aqm "add foo"
   $ hg --config phases.newcommit=secret fix -r .
   $ hg log --template '{rev} {phase}\n'
   1 draft
   0 draft
 
   $ cd ..
 
 Debug output should show what fixer commands are being subprocessed, which is
 useful for anyone trying to set up a new config.
 
   $ hg init debugoutput
   $ cd debugoutput
 
   $ printf "foo\nbar\nbaz\n" > foo.changed
   $ hg commit -Aqm "foo"
   $ printf "Foo\nbar\nBaz\n" > foo.changed
   $ hg --debug fix --working-dir
   subprocess: * $TESTTMP/uppercase.py 1-1 3-3 (glob)
 
   $ cd ..
 
 Fixing an obsolete revision can cause divergence, so we abort unless the user
 configures to allow it. This is not yet smart enough to know whether there is a
 successor, but even then it is not likely intentional or idiomatic to fix an
 obsolete revision.
 
   $ hg init abortobsoleterev
   $ cd abortobsoleterev
 
   $ printf "foo\n" > foo.changed
   $ hg commit -Aqm "foo"
   $ hg debugobsolete `hg parents --template '{node}'`
   1 new obsolescence markers
   obsoleted 1 changesets
   $ hg --hidden fix -r 0
   abort: fixing obsolete revision could cause divergence
   [255]
 
   $ hg --hidden fix -r 0 --config experimental.evolution.allowdivergence=true
   $ hg cat -r tip foo.changed
   FOO
 
   $ cd ..
 
 Test all of the available substitution values for fixer commands.
 
   $ hg init substitution
   $ cd substitution
 
   $ mkdir foo
   $ printf "hello\ngoodbye\n" > foo/bar
   $ hg add
   adding foo/bar
   $ hg --config "fix.fail:command=printf '%s\n' '{rootpath}' '{basename}'" \
   >    --config "fix.fail:linerange='{first}' '{last}'" \
   >    --config "fix.fail:pattern=foo/bar" \
   >    fix --working-dir
   $ cat foo/bar
   foo/bar
   bar
   1
   2
 
   $ cd ..
 
 The --base flag should allow picking the revisions to diff against for changed
 files and incremental line formatting.
 
   $ hg init baseflag
   $ cd baseflag
 
   $ printf "one\ntwo\n" > foo.changed
   $ printf "bar\n" > bar.changed
   $ hg commit -Aqm "first"
   $ printf "one\nTwo\n" > foo.changed
   $ hg commit -m "second"
   $ hg fix -w --base .
   $ hg status
   $ hg fix -w --base null
   $ cat foo.changed
   ONE
   TWO
   $ cat bar.changed
   BAR
 
   $ cd ..
 
 If the user asks to fix the parent of another commit, they are asking to create
 an orphan. We must respect experimental.evolution.allowunstable.
 
   $ hg init allowunstable
   $ cd allowunstable
 
   $ printf "one\n" > foo.whole
   $ hg commit -Aqm "first"
   $ printf "two\n" > foo.whole
   $ hg commit -m "second"
   $ hg --config experimental.evolution.allowunstable=False fix -r '.^'
   abort: cannot fix changeset with children
   [255]
   $ hg fix -r '.^'
   1 new orphan changesets
   $ hg cat -r 2 foo.whole
   ONE
 
   $ cd ..
 
 The --base flag affects the set of files being fixed. So while the --whole flag
 makes the base irrelevant for changed line ranges, it still changes the
 meaning and effect of the command. In this example, no files or lines are fixed
 until we specify the base, but then we do fix unchanged lines.
 
   $ hg init basewhole
   $ cd basewhole
   $ printf "foo1\n" > foo.changed
   $ hg commit -Aqm "first"
   $ printf "foo2\n" >> foo.changed
   $ printf "bar\n" > bar.changed
   $ hg commit -Aqm "second"
 
   $ hg fix --working-dir --whole
   $ cat *.changed
   bar
   foo1
   foo2
 
   $ hg fix --working-dir --base 0 --whole
   $ cat *.changed
   BAR
   FOO1
   FOO2
 
   $ cd ..
 
 The execution order of tools can be controlled. This example doesn't work if
 you sort after truncating, but the config defines the correct order while the
 definitions are out of order (which might imply the incorrect order given the
 implementation of fix). The goal is to use multiple tools to select the lowest
 5 numbers in the file.
 
   $ hg init priorityexample
   $ cd priorityexample
 
   $ cat >> .hg/hgrc <<EOF
   > [fix]
   > head:command = head -n 5
   > head:pattern = numbers.txt
   > head:priority = 1
   > sort:command = sort -n
   > sort:pattern = numbers.txt
   > sort:priority = 2
   > EOF
 
   $ printf "8\n2\n3\n6\n7\n4\n9\n5\n1\n0\n" > numbers.txt
   $ hg add -q
   $ hg fix -w
   $ cat numbers.txt
   0
   1
   2
   3
   4
 
 And of course we should be able to break this by reversing the execution order.
 Test negative priorities while we're at it.
 
   $ cat >> .hg/hgrc <<EOF
   > [fix]
   > head:priority = -1
   > sort:priority = -2
   > EOF
   $ printf "8\n2\n3\n6\n7\n4\n9\n5\n1\n0\n" > numbers.txt
   $ hg fix -w
   $ cat numbers.txt
   2
   3
   6
   7
   8
 
   $ cd ..
 
 It's possible for repeated applications of a fixer tool to create cycles in the
 generated content of a file. For example, two users with different versions of
 a code formatter might fight over the formatting when they run hg fix. In the
 absence of other changes, this means we could produce commits with the same
 hash in subsequent runs of hg fix. This is a problem unless we support
 obsolescence cycles well. We avoid this by adding an extra field to the
 successor which forces it to have a new hash. That's why this test creates
 three revisions instead of two.
 
   $ hg init cyclictool
   $ cd cyclictool
 
   $ cat >> .hg/hgrc <<EOF
   > [fix]
   > swapletters:command = tr ab ba
   > swapletters:pattern = foo
   > EOF
 
   $ echo ab > foo
   $ hg commit -Aqm foo
 
   $ hg fix -r 0
   $ hg fix -r 1
 
   $ hg cat -r 0 foo --hidden
   ab
   $ hg cat -r 1 foo --hidden
   ba
   $ hg cat -r 2 foo
   ab
 
   $ cd ..
 
 We run fixer tools in the repo root so they can look for config files or other
 important things in the working directory. This does NOT mean we are
 reconstructing a working copy of every revision being fixed; we're just giving
 the tool knowledge of the repo's location in case it can do something
 reasonable with that.
 
   $ hg init subprocesscwd
   $ cd subprocesscwd
 
   $ cat >> .hg/hgrc <<EOF
   > [fix]
   > printcwd:command = "$PYTHON" -c "import os; print(os.getcwd())"
   > printcwd:pattern = relpath:foo/bar
   > filesetpwd:command = "$PYTHON" -c "import os; print('fs: ' + os.getcwd())"
   > filesetpwd:pattern = set:**quux
   > EOF
 
   $ mkdir foo
   $ printf "bar\n" > foo/bar
   $ printf "quux\n" > quux
   $ hg commit -Aqm blah
 
   $ hg fix -w -r . foo/bar
   $ hg cat -r tip foo/bar
   $TESTTMP/subprocesscwd
   $ cat foo/bar
   $TESTTMP/subprocesscwd
 
   $ cd foo
 
   $ hg fix -w -r . bar
   $ hg cat -r tip bar ../quux
   $TESTTMP/subprocesscwd
   quux
   $ cat bar ../quux
   $TESTTMP/subprocesscwd
   quux
   $ echo modified > bar
   $ hg fix -w bar
   $ cat bar
   $TESTTMP/subprocesscwd
 
 Apparently fixing p1() and its descendants doesn't include wdir() unless
 explicitly stated.
 
   $ hg fix -r '.::'
   $ hg cat -r . ../quux
   quux
   $ hg cat -r tip ../quux
   fs: $TESTTMP/subprocesscwd
   $ cat ../quux
   quux
 
 Clean files are not fixed unless explicitly named
   $ echo 'dirty' > ../quux
 
   $ hg fix --working-dir
   $ cat ../quux
   fs: $TESTTMP/subprocesscwd
 
   $ cd ../..
 
 Tools configured without a pattern are ignored. It would be too dangerous to
 run them on all files, because this might happen while testing a configuration
 that also deletes all of the file content. There is no reasonable subset of the
 files to use as a default. Users should be explicit about what files are
 affected by a tool. This test also confirms that we don't crash when the
 pattern config is missing, and that we only warn about it once.
 
   $ hg init nopatternconfigured
   $ cd nopatternconfigured
 
   $ printf "foo" > foo
   $ printf "bar" > bar
   $ hg add -q
   $ hg fix --debug --working-dir --config "fix.nopattern:command=echo fixed"
   fixer tool has no pattern configuration: nopattern
   $ cat foo bar
   foobar (no-eol)
   $ hg fix --debug --working-dir --config "fix.nocommand:pattern=foo.bar"
   fixer tool has no command configuration: nocommand
 
   $ cd ..
 
 Tools can be disabled. Disabled tools do nothing but print a debug message.
 
   $ hg init disabled
   $ cd disabled
 
   $ printf "foo\n" > foo
   $ hg add -q
   $ hg fix --debug --working-dir --config "fix.disabled:command=echo fixed" \
   >                              --config "fix.disabled:pattern=foo" \
   >                              --config "fix.disabled:enabled=false"
   ignoring disabled fixer tool: disabled
   $ cat foo
   foo
 
   $ cd ..
 
 Test that we can configure a fixer to affect all files regardless of the cwd.
 The way we invoke matching must not prohibit this.
 
   $ hg init affectallfiles
   $ cd affectallfiles
 
   $ mkdir foo bar
   $ printf "foo" > foo/file
   $ printf "bar" > bar/file
   $ printf "baz" > baz_file
   $ hg add -q
 
   $ cd bar
   $ hg fix --working-dir --config "fix.cooltool:command=echo fixed" \
   >                      --config "fix.cooltool:pattern=glob:**"
   $ cd ..
 
   $ cat foo/file
   fixed
   $ cat bar/file
   fixed
   $ cat baz_file
   fixed
 
   $ cd ..
 
 Tools should be able to run on unchanged files, even if they set :linerange.
 This includes a corner case where deleted chunks of a file are not considered
 changes.
 
   $ hg init skipclean
   $ cd skipclean
 
   $ printf "a\nb\nc\n" > foo
   $ printf "a\nb\nc\n" > bar
   $ printf "a\nb\nc\n" > baz
   $ hg commit -Aqm "base"
 
   $ printf "a\nc\n" > foo
   $ printf "a\nx\nc\n" > baz
 
   $ cat >> print.py <<EOF
   > import sys
   > for a in sys.argv[1:]:
   >    print(a)
   > EOF
 
   $ hg fix --working-dir foo bar baz \
   >        --config "fix.changedlines:command=\"$PYTHON\" print.py \"Line ranges:\"" \
   >        --config 'fix.changedlines:linerange="{first} through {last}"' \
   >        --config 'fix.changedlines:pattern=glob:**' \
   >        --config 'fix.changedlines:skipclean=false'
 
   $ cat foo
   Line ranges:
   $ cat bar
   Line ranges:
   $ cat baz
   Line ranges:
   2 through 2
 
   $ cd ..
 
 Test various cases around merges. We were previously dropping files if they were
 created on only the p2 side of the merge, so let's test permutations of:
 *   added, was fixed
 *   added, considered for fixing but was already good
 *   added, not considered for fixing
 *   modified, was fixed
 *   modified, considered for fixing but was already good
 *   modified, not considered for fixing
 
 Before the bug was fixed where we would drop files, this test demonstrated the
 following issues:
 *   new_in_r1.ignored, new_in_r1_already_good.changed, and
 >   mod_in_r1_already_good.changed were NOT in the manifest for the merge commit
 *   mod_in_r1.ignored had its contents from r0, NOT r1.
 
 We're also setting a named branch for every commit to demonstrate that the
 branch is kept intact and there aren't issues updating to another branch in the
 middle of fix.

 #require no-reposimplestore
 
 Testing the case when there is no infinitepush extension present on the client
 side and the server routes each push to bundlestore. This case is very much
 similar to CI use case.

 Understanding how data is stored on the bundlestore in server
 -------------------------------------------------------------
 
 There are two things, filebundlestore and index
   $ ls ../repo/.hg/scratchbranches
   filebundlestore
   index
 
 filebundlestore stores the bundles
   $ ls ../repo/.hg/scratchbranches/filebundlestore/3b/41/
   3b414252ff8acab801318445d88ff48faf4a28c3
 
 index/nodemap stores a map of node id and file in which bundle is stored in filebundlestore
   $ ls ../repo/.hg/scratchbranches/index/
   nodemap
   $ ls ../repo/.hg/scratchbranches/index/nodemap/
   6cb0989601f1fb5805238edfb16f3606713d9a0b
 
   $ cd ../repo

 Test that update also updates the lfdirstate of 'unsure' largefiles after
 hashing them:
 
 The previous operations will usually have left us with largefiles with a mtime
 within the same second as the dirstate was written.
 The lfdirstate entries will thus have been written with an invalidated/unset
 mtime to make sure further changes within the same second is detected.
 We will however occasionally be "lucky" and get a tick between writing
 largefiles and writing dirstate so we get valid lfdirstate timestamps. The
 following verification is thus disabled but can be verified manually.

 A linear merge will update standins before performing the actual merge. It will
 do a lfdirstate status walk and find 'unset'/'unsure' files, hash them, and
 update the corresponding standins.
 Verify that it actually marks the clean files as clean in lfdirstate so
 we don't have to hash them again next time we update.

 Test a fatal error interrupting an update. Verify that status report dirty
 files correctly after an interrupted update. Also verify that checking all
 hashes reveals it isn't clean.
 
 Start with clean dirstates:
   $ hg up --quiet --clean --rev "8^"
   $ sleep 1
   $ hg st
 Update standins without updating largefiles - large1 is modified and largeX is
 added:
   $ cat << EOF > ../crashupdatelfiles.py
   > import hgext.largefiles.lfutil
   > def getlfilestoupdate(oldstandins, newstandins):
   >      raise SystemExit(7)
   > hgext.largefiles.lfutil.getlfilestoupdate = getlfilestoupdate
   > EOF
   $ hg up -Cr "8" --config extensions.crashupdatelfiles=../crashupdatelfiles.py
   [7]
 Check large1 content and status ... and that update will undo modifications:
   $ cat large1
   large1 in #3
   $ hg st
   M large1
   ! largeX
   $ hg up -Cr .
   getting changed largefiles
   2 largefiles updated, 0 removed
   2 files updated, 0 files merged, 0 files removed, 0 files unresolved
   $ cat large1
   manually modified before 'hg transplant --continue'

 Force largefiles rehashing and check that all changes have been caught by
 status and update:
   $ rm .hg/largefiles/dirstate
   $ hg st
 
   $ cd ..
 
 Test that "hg convert" avoids copying largefiles from the working
 directory into store, because "hg convert" doesn't update largefiles
 in the working directory (removing files under ".cache/largefiles"
 forces "hg convert" to copy corresponding largefiles)

 Test that branchheads cache is updated correctly when doing a strip in which
 the parent of the ancestor node to be stripped does not become a head and also,
 the parent of a node that is a child of the node stripped becomes a head (node
 3). The code is now much simpler and we could just test a simpler scenario
 We keep it the test this way in case new complexity is injected.

 branch name with the wdir branch name instead of the actual branch name (which
 should stay unchanged if --keepbranches is passed), and erroneously assumed
 that an otherwise empty changeset should be created because of the incorrectly
 assumed branch name change.
