stablerangecache: include units in ui.progress() calls

stablerange: include units in ui.progress() calls

tests: add test demonstarting issue5833 is fixed Previous patch which fixed issue5832 also fixed issue5833 as the root cause for both was same. This patch adds test of issue5833 as well. CHANEGLOG entry is also added for the fixed issues.

utility: convert node from MultipleSuccessorsError to rev numbers (issue5832) utility.builddependencies() deals with rev numbers but MultipleSuccessorsError returns nodeid which breaks the function and also breaks instability resolution. Previou patch demonstrate the breakage. This patch makes sure we convert those nodeids to rev numbers before processing ahead.

tests: add a test demonstarting issue5832 traceback The traceback will be fixed in upcoming patches.

CHANGELOG: add an entry about `hg evolve --abort` Previous patches added a new flag `--abort` for `hg evolve` which aborts an interrupted evolve. Currently this only works for orphan resolution cases which is very common and most people use `evolve` for that. So let's add an entry about that.

evolve: restore bookmarks correctly after `hg evolve --abort` This patch adds logic to store bookmark movements in evolvestate class and restore bookmarks to their original place if `hg evolve --abort` is called.

topic-ext: restrict the format of topic names This patch restrict the format of topic names to make sure they consist only of alphanumeric, '_' and '-' characters.

serverminitopic: wrap context.changectx.branch instead of context.changectx Recently some changes in core resulted in this wrapping of class leading to an infinite recursion. Let's wrap the particular function instead of wrapping the whole command. This fixes test-minitopic.t which was breaking.

templatekw: remove obsfatedata templatekw Individuals fields are available in core as single template functions.

evolve: do not exit 1 when there are no troubled changesets (issue5823) There are possibly other cases we also do not wish to exit non-zero for in this function, but I did not analyze them closely and am just looking at resolving issue5823.

changelog: add an entry about the memory fixes

safeguard: use self instead of repo in noautopublishrepo.checkpush() Referring to repo here was somehow preventing it from being garbage-collected (important in hgweb, where currently every request gets a new repo).

stablerangecache: use self instead of repo in stablerangerepo.stablerange() Referring to repo here was somehow preventing it from being garbage-collected (important in hgweb, where currently every request gets a new repo).

obscache: use self instead of repo in obscacherepo.updatecaches() Referring to repo here was somehow preventing it from being garbage-collected (important in hgweb, where currently every request gets a new repo).

templatekw: fix templatedata for 46

style: fix a couple of pyflakes complains

evolve: add a `--abort` flag for `hg evolve` command This patch adds a new flag `--abort` to `hg evolve` command which will abort the interrupted evolve going on undoes the changes created by the evolve command till now. The changes are bookmark movements, creation of evolved commits, obsolete the old commits in favor of evolved commits. In case when user changed things while the interrupted evolve, like did some actions which created a new commit on top of evolved commits, or changed phase of evolved commits to public, the evolve fails to abort as we should not strip out the new commit formed by user neither we can strip the public changeset. The abort fails and tell user to use `hg evolve --stop` instead. Right now bookmark movement is broken, and will be fixed in upcoming patches. Tests are added for the new flag.

evolve: don't allow updating or commiting when there is interrupted evolve We should make things simple in the starting and restrict user from doing things which can lead to problems. This is same as the rebase behavior.

evolve: internationalize the entry of --list in hg evolve help

evolve: add evolvestate as an argument to _finalizerelocate() This will help us to store bookmark changes to evolvestate to revert them in case when `hg evolve --abort` is called.

evolve: add evolvestate as an argument to evolvecmd.relocate() This will help us in passing it to _finalizerelocate() and store the bookmark changes which happend.

tests: add test about handling phase-divergent merges We don't handle phase-divergent merges and we should. Upcoming patches will add the ability to handle them.

evolve: show a message when evolution leads to no changes to commit In case of orphan resolution, evolution may result in no changes to commit. This patch adds a use message in such cases. This is same as the rebase behavior.

evolve: pass the instability category to relocate() and _finalizerelocate() This patch adds category argument to relocate() and _finalizerelocate() functions to take the type of instability which we are processing so that we perform actions accordingly.

tests: add more tests for solving phase-divergence using `hg evolve` This patch adds more tests for resolving phase-divergence caused due to fold or split using `hg evolve` command. The resolution in case of split is not very good and will be fixed in upcoming patches

evolve: handle interrupted phase-divergence resolution gracefully This patch adds logic to handle the interrupted phase-divergence resolution by `hg evolve` command gracefully. We first complete the relocation of the changeset and then do the divergence resolution. Previous functions moved required code separate fucntions so that we can use them here.

evolve: move logic to resolve phase-divergence in a new function This patch moves logic which does the revert and create a commit on top of public changeset because we need to repeat that logic while handling continuation of `hg evolve` when there are conflicts while rebasing the phase-divergent changeset.
