tests: test that `hg obslog wdir()` aborts with a useful message

obshistory: make obslog work when a commit doesn't have any description This logic is taken from logcmdutil.changesetprinter class. It checks that commit description is not empty before extracting the first line (before this patch it would try to index an empty list). Stripping description also makes obslog behave more like regular log when there are trailing/leading whitespaces.

obshistory: use a more appropriate type for obslog entries cand is actually a regular changeset and not 'M' (graphmod.MISSINGPARENT). And 'M' is only used for graph edges, but cand is drawn as a graph node. Visually there's no effect, but the code makes more sense this way.

evolve: don't pass stringified int to repo.__getitem__ We were doing repo['-1'], which is now deprecated. Switch to repo['tip'], which is much clearer anyway (I initially thought this was nullrev and sent an incorrect patch until Pierre-Yves corrected me).

patch: offer the user a chance to fix the patch if it fails to apply The experience is still not great, but better than purely dropping the changes.

amend: add a new flag `--patch` to `hg amend` This patch adds a new flag `--patch` to `hg amend` which pops up an editor with the patch of working directory parent which you can change, and when you exit the editor the patch with changes is applied to current working directory with old changeset being obsoleted in favour of new one created by the applied patch. If supplied filenames, only those filenames are present in the popped editor and rest files stay the same way in the commit as they were. The extension of the file which opens up in editor is '.diff', we cannot have it as '.patch' as there will be develwarns related to that. We need to change to patch core and undo some change to achieve this. The implementation does not use any core API rather it has picked chunks from API which are required. One main reason to not use core import API is that we have to change wdir parent before using patch.patch() which I will like to avoid to make sure we handle merge cases too. While writing this patch I have spend lot of time try to use internal API's to work for this but none of them served the purpose well. If I have time in future and work on similar problem again, I am going to write better high-level API's which uses patchstore to achieve this. A new test file test-amend-patch.t which contains a lot of testing of the feature.

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.

evolve: store the precursor of phase-divergent in evolvestate This patch makes `hg evolve` store the precursor of phase-divergent changeset in evolvestate so that we don't need to calculate that again.

evolve: move logic to complete interrupted relocation to new fn This moves logic which completed the interrupted relocation to it's own separate function as we will need that function in continuing phase-divergence and content-divergence too.

evolve: move logic to complete interrupted orphan resolution to new fn This patch moves logic which completes an interrupted orphan resolution to it's own new function. We will defining such functions for completing phase-divergence and content-divergence too.

evolve: write data to evolvestate in case on conflicts in phase-divergence This patch makes phase-divergence resolution write data to evolvestate instead of graftstate. The `evolve --continue` handling of phase-divergence is broken which will be done in upcoming patches.

evolve: explicitly turn revs to list before storing into evolvestate The cbor library which we are using cannot handle encoding and decoding Python sets, and revs was set there. Let's convert revs explicitly to list to make sure we don't try writing sets.

tests: add tests of content+parent change creating phase-divergence This patch adds tests which shows handling of phase divergence cases by `hg evolve` command which involved content+parent change. The conflicts case is not handled and will be fixed in upcoming patches.

tests: show first line of commit message in test-evolve-phase-divergence.t This patch adds 'firstline' filter to description in the log template.

evolve: make sure bookmarks are moved after phase-divergence resolution This patch adds logic to move bookmarks from the rebased node to the phase-divergence resolved node.

evolve: use the new rebased changeset to resolve phase-divergence When there is a parent change in phase-divergence, `hg evolve` first rebases the diveregent changeset on parent of public changeset and then continue the resolution of phase-divergence *but* we used to continue with the old divergent changeset rather than the new rebased one. This patch makes sure we use the new rebased changeset to proceed with the resolution. Tests changes shows that it fixes things which were broken earlier.

evolvecmd: add a detailed comment and some newlines This patch adds a detailed comment on a chunk and some newlines to make things look better and more understandable for upcoming patches.

tests: add one more test case about handling of phase-divergence by evolve This patch adds a test case when phasedivergence is caused by rebase command and there is parent change involved. As the tests show, we are not handling things correctly here. Upcoming patches will fix that. Fixing things in later patches showed there was a wrong case in one another test which will be fixed by later patches, so let's add description on why that test is wrong in this patch.

tests: add more tests for handling of phase divergence by `hg evolve` This patch adds more tests related to handling of phase-divergence by `hg evolve` command.

tests: temporary delete the merge test of handling phase divergence This patch temporary deletes the merge test of handling phase divergence by `hg evolve` command to that other important tests can be plugged in before this. This will make adding more tests easy. As I say, this is temporary to ease out adding more tests, the test will be added back.

tests: various comment on test-evolve-phase-divergence

tests: make test-evolve-phase-divergence more descriptive This patch adds description to what each part is doing in test-evolve-phase-divergence.t and some commands which should be used to analyze the divergence before resolving that.

compat: use updateresult API if available The status return is no longer a tuple, we access attribute instead.

compat: provide an explicit default value to the 'odiff' config There is a devel warning about this now.

compat: keep passing arguments as keyword argument Otherwise, This break with new changes in upstream Mercurial.

compat: search for stringmatcher in the new location More of util has been split into sub modules.

rebase: update the rebase wrapping to works with hg 4.6 Mercurial core commit bd0086bd3af4 removed _makeextrafn hence breaking our wrapping. Update the code to wrap rebaseruntime directly in a way that's compatible with hg 4.1+.

compat: call current obsolete.createmarkers(), not one from load time Other extensions may wrap obsolete.createmarkers(). If they do, we should call their wrapped version. However, since f61a23a84dac (compat: add wrapper for obsolete.createmarkers() that accepts "operation" arg, 2018-03-16), we started storing the version of the function as it was when our compat module was loaded. This broke an extension we use internally at Google.
