run-tests: print more information on unnecessary glob matching
Extend the message with the test name and the approximate line number. (The
line number is the one of the command producing the output.)
Finding the line to fix is easier now.
old message:
......
Info, unnecessary glob: at a/b/c (glob)
..
new message:
......
Info, unnecessary glob in test-example.t (after line 9): at a/b/c (glob)
..
The test result is still pass as before.

"""interactive history editing
With this extension installed, Mercurial gains one new command: histedit. Usage
is as follows, assuming the following history::
@ 3[tip] 7c2fd3b9020c 2009-04-27 18:04 -0500 durin42
| Add delta
|
o 2 030b686bedc4 2009-04-27 18:04 -0500 durin42
| Add gamma
|
o 1 c561b4e977df 2009-04-27 18:04 -0500 durin42
| Add beta
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
If you were to run ``hg histedit c561b4e977df``, you would see the following
file open in your editor::
pick c561b4e977df Add beta
pick 030b686bedc4 Add gamma
pick 7c2fd3b9020c Add delta
# Edit history between c561b4e977df and 7c2fd3b9020c
#
# Commands:
# p, pick = use commit
# e, edit = use commit, but stop for amending
# f, fold = use commit, but fold into previous commit (combines N and N-1)
# d, drop = remove commit from history
# m, mess = edit message without changing commit content
#
In this file, lines beginning with ``#`` are ignored. You must specify a rule
for each revision in your history. For example, if you had meant to add gamma
before beta, and then wanted to add delta in the same revision as beta, you
would reorganize the file to look like this::
pick 030b686bedc4 Add gamma
pick c561b4e977df Add beta
fold 7c2fd3b9020c Add delta
# Edit history between c561b4e977df and 7c2fd3b9020c
#
# Commands:
# p, pick = use commit
# e, edit = use commit, but stop for amending
# f, fold = use commit, but fold into previous commit (combines N and N-1)
# d, drop = remove commit from history
# m, mess = edit message without changing commit content
#
At which point you close the editor and ``histedit`` starts working. When you
specify a ``fold`` operation, ``histedit`` will open an editor when it folds
those revisions together, offering you a chance to clean up the commit message::
Add beta
***
Add delta
Edit the commit message to your liking, then close the editor. For
this example, let's assume that the commit message was changed to
``Add beta and delta.`` After histedit has run and had a chance to
remove any old or temporary revisions it needed, the history looks
like this::
@ 2[tip] 989b4d060121 2009-04-27 18:04 -0500 durin42
| Add beta and delta.
|
o 1 081603921c3f 2009-04-27 18:04 -0500 durin42
| Add gamma
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
Note that ``histedit`` does *not* remove any revisions (even its own temporary
ones) until after it has completed all the editing operations, so it will
probably perform several strip operations when it's done. For the above example,
it had to run strip twice. Strip can be slow depending on a variety of factors,
so you might need to be a little patient. You can choose to keep the original
revisions by passing the ``--keep`` flag.
The ``edit`` operation will drop you back to a command prompt,
allowing you to edit files freely, or even use ``hg record`` to commit
some changes as a separate commit. When you're done, any remaining
uncommitted changes will be committed as well. When done, run ``hg
histedit --continue`` to finish this step. You'll be prompted for a
new commit message, but the default commit message will be the
original message for the ``edit`` ed revision.
The ``message`` operation will give you a chance to revise a commit
message without changing the contents. It's a shortcut for doing
``edit`` immediately followed by `hg histedit --continue``.
If ``histedit`` encounters a conflict when moving a revision (while
handling ``pick`` or ``fold``), it'll stop in a similar manner to
``edit`` with the difference that it won't prompt you for a commit
message when done. If you decide at this point that you don't like how
much work it will be to rearrange history, or that you made a mistake,
you can use ``hg histedit --abort`` to abandon the new changes you
have made and return to the state before you attempted to edit your
history.
If we clone the histedit-ed example repository above and add four more
changes, such that we have the following history::
@ 6[tip] 038383181893 2009-04-27 18:04 -0500 stefan
| Add theta
|
o 5 140988835471 2009-04-27 18:04 -0500 stefan
| Add eta
|
o 4 122930637314 2009-04-27 18:04 -0500 stefan
| Add zeta
|
o 3 836302820282 2009-04-27 18:04 -0500 stefan
| Add epsilon
|
o 2 989b4d060121 2009-04-27 18:04 -0500 durin42
| Add beta and delta.
|
o 1 081603921c3f 2009-04-27 18:04 -0500 durin42
| Add gamma
|
o 0 d8d2fcd0e319 2009-04-27 18:04 -0500 durin42
Add alpha
If you run ``hg histedit --outgoing`` on the clone then it is the same
as running ``hg histedit 836302820282``. If you need plan to push to a
repository that Mercurial does not detect to be related to the source
repo, you can add a ``--force`` option.
