discovery: list new remote heads in prepush() on --debug

With this patch applied, Mercurial will list the hashes of new remote heads
if push --debug aborts because of new remote heads (option -f/--force not set).

Example:

  $ hg push --debug repo1
  using http://example.org/repo1
  http auth: user johndoe, password not set
  sending between command
  pushing to http://example.org/repo1
  sending capabilities command
  capabilities: changegroupsubset stream=1 lookup pushkey unbundle=HG10GZ,HG10BZ,HG10UN branchmap
  sending heads command
  searching for changes
  common changesets up to 609edbc7853f
  sending branchmap command
  new remote heads on branch 'default'        <- new output line
  new remote head 5862c07f53a2                <- new output line
  abort: push creates new remote heads on branch 'default'!
  (did you forget to merge? use push -f to force)

Compare to without --debug (not changed by this patch, including it here
for reference purposes only):

  $ hg push repo1
  pushing to http://example.org/repo1
  searching for changes
  abort: push creates new remote heads on branch 'default'!
  (did you forget to merge? use push -f to force)

Motivation for this change:

'hg outgoing' may list a whole lot of benign changesets plus an odd changeset
that will trigger the "new remote heads" abort. It can be hard to spot that
single unwanted changeset (it may be an old forgotten experiment, lingering
in the local repo).

"hg log -r 'heads(outgoing())'" might be useful, but that also lists a head
that may be benign on push.

Inside prepush(), we already know which heads are causing troubles on 'hg push'.
Why not make that info available (at least on --debug)?

This would also be helpful for doing remote support, as the supporter can ask
the user to paste the output of 'hg push --debug' on error and then ask further
questions about the heads listed.

  $ hg init repo
  $ cd repo
  $ echo 123 > a
  $ echo 123 > c
  $ echo 123 > e
  $ hg add a c e
  $ hg commit -m "first" a c e
  $ echo 123 > b

should show b unknown

  $ hg status
  ? b
  $ echo 12 > c

should show b unknown and c modified

  $ hg status
  M c
  ? b
  $ hg add b

should show b added and c modified

  $ hg status
  M c
  A b
  $ hg rm a

should show a removed, b added and c modified

  $ hg status
  M c
  A b
  R a
  $ hg revert a

should show b added, copy saved, and c modified

  $ hg status
  M c
  A b
  $ hg revert b

should show b unknown, and c modified

  $ hg status
  M c
  ? b
  $ hg revert --no-backup c

should show unknown: b

  $ hg status
  ? b
  $ hg add b

should show b added

  $ hg status b
  A b
  $ rm b

should show b deleted

  $ hg status b
  ! b
  $ hg revert -v b
  forgetting b

should not find b

  $ hg status b
  b: No such file or directory

should show a c e

  $ ls
  a
  c
  e

should verbosely save backup to e.orig

  $ echo z > e
  $ hg revert --all -v
  saving current version of e as e.orig
  reverting e

should say no changes needed

  $ hg revert a
  no changes needed to a

should say file not managed

  $ echo q > q
  $ hg revert q
  file not managed: q
  $ rm q

should say file not found

  $ hg revert notfound
  notfound: no such file in rev 334a9e57682c
  $ touch d
  $ hg add d
  $ hg rm a
  $ hg commit -m "second"
  $ echo z > z
  $ hg add z
  $ hg st
  A z
  ? e.orig

should add a, remove d, forget z

  $ hg revert --all -r0
  adding a
  removing d
  forgetting z

should forget a, undelete d

  $ hg revert --all -rtip
  forgetting a
  undeleting d
  $ rm a *.orig

should silently add a

  $ hg revert -r0 a
  $ hg st a
  A a
  $ hg rm d
  $ hg st d
  R d

should silently keep d removed

  $ hg revert -r0 d
  $ hg st d
  R d

  $ hg update -C
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ chmod +x c
  $ hg revert --all
  reverting c

should print non-executable

  $ test -x c || echo non-executable
  non-executable

  $ chmod +x c
  $ hg commit -m exe

  $ chmod -x c
  $ hg revert --all
  reverting c

should print executable

  $ test -x c && echo executable
  executable

  $ cd ..


Issue241: update and revert produces inconsistent repositories

  $ hg init a
  $ cd a
  $ echo a >> a
  $ hg commit -A -d '1 0' -m a
  adding a
  $ echo a >> a
  $ hg commit -d '2 0' -m a
  $ hg update 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ mkdir b
  $ echo b > b/b

should fail - no arguments

  $ hg revert -rtip
  abort: no files or directories specified; use --all to revert the whole repo
  [255]

should succeed

  $ hg revert --all -rtip
  reverting a


Issue332: confusing message when reverting directory

  $ hg ci -A -m b
  adding b/b
  created new head
  $ echo foobar > b/b
  $ mkdir newdir
  $ echo foo > newdir/newfile
  $ hg add newdir/newfile
  $ hg revert b newdir
  reverting b/b
  forgetting newdir/newfile
  $ echo foobar > b/b
  $ hg revert .
  reverting b/b


reverting a rename target should revert the source

  $ hg mv a newa
  $ hg revert newa
  $ hg st a newa
  ? newa

  $ cd ..

  $ hg init ignored
  $ cd ignored
  $ echo '^ignored$' > .hgignore
  $ echo '^ignoreddir$' >> .hgignore
  $ echo '^removed$' >> .hgignore

  $ mkdir ignoreddir
  $ touch ignoreddir/file
  $ touch ignoreddir/removed
  $ touch ignored
  $ touch removed

4 ignored files (we will add/commit everything)

  $ hg st -A -X .hgignore
  I ignored
  I ignoreddir/file
  I ignoreddir/removed
  I removed
  $ hg ci -qAm 'add files' ignored ignoreddir/file ignoreddir/removed removed

  $ echo >> ignored
  $ echo >> ignoreddir/file
  $ hg rm removed ignoreddir/removed

should revert ignored* and undelete *removed

  $ hg revert -a --no-backup
  reverting ignored
  reverting ignoreddir/file
  undeleting ignoreddir/removed
  undeleting removed
  $ hg st -mardi

  $ hg up -qC
  $ echo >> ignored
  $ hg rm removed

should silently revert the named files

  $ hg revert --no-backup ignored removed
  $ hg st -mardi
