merge: simplify mergestate iter

resolve: simplify "finished" message The recently introduced message was: no unresolved files; you may continue your unfinished operation This had three problems: - looks a bit like an error message because it's not saying "we've just resolved the last file" - refers to "unfinished operation", which won't be the case with "update" or "merge" - introduces semicolons to error messages, which is stylistically questionable I've simplified this to: no more unresolved files In the future, if we want to prompt someone to continue a particular operation, we should use a hint style: no more unresolved files (use 'hg graft --continue' to finish grafting)

resolve: print message when no unresolved files remain (issue4214) When using resolve, users often have to consult with the output of |hg resolve -l| to see if any unresolved files remain. This step is tedious and adds overhead to resolving. This patch will notify a user if there are no unresolved files remaining after executing |hg resolve|:: no unresolved files; you may continue your unfinished operation The patch stops short of telling the user exactly what command should be executed to continue the unfinished operation. That is because this information is not currently captured anywhere. This would make a compelling follow-up feature.

resolve: print warning when no work performed (issue4208) Previously, if the paths specified as arguments to |hg resolve| were invalid, they were silently ignored and a no-op would ensue. This patch fixes that in some scenarios. If none of the paths specified to |hg resolve| match a path that is in mergestate, a warning will be emitted. Ideally, a warning would be emitted for every path/pattern specified that doesn't match anything. To achieve this would require significant refactoring of the matching subsystem. That work is beyond the scope of this patch series. Something is better than nothing and this patch gets us something.

resolve: abort when not applicable (BC) The resolve command is only relevant when mergestate is present. This patch will make resolve abort when no mergestate is present. This change will let people know when they are using resolve when they shouldn't be. This change will let people know when their use of resolve doesn't do anything. Previously, |hg resolve -m| would allow mergestate to be created. This patch now forbids that. Strictly speaking, this is backwards incompatible. The author of this patch believes creating mergestate via resolve doesn't make much sense and this side-effect was unintended.

resolve: split test Part of test-resolve.t is split into multiple tests to create an injection point for new tests that will be added in subsequent patches.

resolve: use early continue and deindent

mergestate: consistently set variables to None Some code branches and exceptional circumstances such as empty mergestate files could result in mergestate._local and mergestate._other not being defined or reset to None. These variables are now correctly set to None when they should be.

changegroup: refactor outgoing logic into a function Extensions that add to bundle2 will want to know which commits are outgoing so they can bundle data that is appropriate to those commits. This moves the logic for figuring that out to a separate function so extensions can do the same computation.

bundle2: fix bundle2 pulling all revs on empty pulls When bundle2 was enabled, if hg pull had no commits to pull, it would print 'no changes found' and then download the entire repository from the server. This was caused by heads and common being set to None, which gets treated as heads=cl.heads() and common=[nullid], which means download the entire repo. Pulling bundles without a changegroup is a valid use case (like if we're just updating bookmarks), so this modifes the bundle code to allow not adding changegroups.

exchange: fix bad indentation Those two lines where double indented for no good reasons.

exchange: propagate arguments to the _getbundleextrapart function The arguments was wrongly propagated (again).

bundle2: fix configuration name mismatch During pulls bundle2 was checking server.bundle2, but during pushes it was checking experimental.bundle2. This makes them both experimental.bundle2.

cmdutil: omit redundant "savecommitmessage()" in "tryimportone()" The preceding patch causes that "makememctx()" with "editor" argument saves (manually edited) commit message into ".hg/last-message.txt": saving itself is executed indirectly in "memctx.__init__()". This makes it redundant to invoke "savecommitmessage()" on caller side of "makememctx()". This patch omits such redundant "savecommitmessage()" invocation in "tryimportone()". "tryimportone()" uses one of "commiteditor" or "commitforceeditor" as "editor" argument, and this causes saving commit message always.

amend: use "editor" argument for "memctx.__init__" to save commit message This patch uses "editor" argument of "memctx.__init__" to save commit message, instead of explicit editor invocation and saving commit message by "localrepository.savecommitmessage()". By passing one of "commiteditor" or "commitforceeditor" as "editor", "memctx.__init__" saves commit message, even when editor invocation is not needed.

histedit: pass "editor" argument to "memctx.__init__()" for "collapse" command The preceding patch causes that "memctx.__init__()" with "editor" argument invokes editor and saves edited commit message into ".hg/last-message.txt". This patch passes "editor" argument to "memctx.__init__()" instead of explicit invocations of "commitforceeditor()" and "savecommitmessage()" for "collapse" command.
