templates: add filter to reverse list
The filter supports only lists because for lists, it’s straightforward to
implement. Reversing text doesn’t seem very useful and is hard to implement.
Reversing the bytes would break multi-bytes encodings. Reversing the code
points would break characters consisting of multiple code points. Reversing
graphemes is non-trivial without using a library not included in the standard
library.
====================================
Testing head checking code: Case E-3
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category E: case involving changeset on multiple branch
TestCase 8: moving only part of the interleaved branch away, creating 2 heads
.. old-state:
..
.. * 2-changeset on branch default
.. * 1-changeset on branch Z (between the two other)
..
.. new-state:
..
.. * 2-changeset on branch default, on untouched, the other moved
.. * 1-changeset on branch Z (at the same location)
..
.. expected-result:
..
.. * push rejected

Test setup
----------
$ mkdir E1
$ cd E1
$ setuprepos
creating basic server and client repo
updating to branch default
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd client
$ hg branch Z
marked working directory as branch Z
(branches are permanent and global, did you want a bookmark?)
$ mkcommit B0
$ hg branch default --force
marked working directory as branch default
$ mkcommit C0
created new head
$ hg push --new-branch
pushing to $TESTTMP/E1/server
searching for changes
adding changesets
adding manifests
adding file changes
added 2 changesets with 2 changes to 2 files
$ hg up 0
0 files updated, 0 files merged, 3 files removed, 0 files unresolved
$ mkcommit C1
created new head
$ hg debugobsolete `getid "desc(C0)" ` `getid "desc(C1)"`
1 new obsolescence markers
obsoleted 1 changesets
$ hg log -G --hidden

Actual testing
--------------
$ hg push -r 'desc("C1")'
pushing to $TESTTMP/E1/server
searching for changes
abort: push creates new remote head dc44c53142f0
(merge or see 'hg help push' for details about pushing new heads)
