annotate: rewrite long short-circuit statement by if-elif-else

revert: use modified information from both statuses Using status information against the target ensures we are catching all files with modifications that need reverting. We still need to distinguish fresh modifications for backup purpose. test-largefile is affected because it reverted a file that needs no content change.

revert: drop special case handling for file unknown in parent We had a special case for file not caught by any categories. It was aimed at files missing in wc and wc's parent but existing in the target revision. This is now properly handled using status information.

revert: use "remove" information from both statuses Using status information against the target to make sure we are catching all files that need to be re-added. We still need to distinguish fresh removal because they use a different message.

revert: process removed files missing in target as clean If a file does not exist in target and is marked as removed in the dirstate, we can mark it as clean. There are no changes needed to revert it.

revert: also track clean files Tracking clean files is the simplest way to be able to reports files that need no changes. So we explicitly retrieve them. This fixes a couple of test outputs where the lack of changes was not reported.

revert: triage "deleted" files into more appropriate categories Status can return file as "deleted". This is only a special case related to working directory state: file is recorded as tracked but no file exists on disk. This will never be a state obtainable from manifest comparisons. "Deleted" files have another working directory status shadowed by the lack of file. They will -alway- be touched by revert. The "lack of file" can be seen as a modification. The file will never match the same "content" as in the revert target. From there we have two options: 1. The file exists in the target and can be seen as "modified". 2. The file does not exist in the target and can be seen as "added". So now we just dispatch elements from delete into appropriate categories.

unshelve: silence internal revert This prepares for upcoming revert changes.

tests: fixup issue markers to make check-commit happy

incoming: don't request heads that already are common Pull would send a getbundle command where common heads were sent both as common and head, even though there is no reason to request a common head. The request was thus twice as big as necessary and more likely to hit HTTP header size limits. Instead, don't request heads that already are common. This is fixed in bundlerepo.getremotechanges . It could perhaps also have been fixed in discovery.findcommonincoming but that would have a bigger impact.

tests: improve test coverage for discovery and actual parameters for pulling

changectx: ancestor should only prefer merge.preferancestor if it is a revision The value '*' currently designates that bid merge should be used. The best way to test bid merge is to set preferancestor=* in the configuration file ... but then it would abort with unknown revision '*' when other code paths ended up in changectx.ancestor . Instead, just skip and ignore the value '*' when looking for a preferred ancestor.

merge: show the scary multiple ancestor hint for merges only, not for updates Updates with uncommited changes will always only have one ancestor - the parent revision. Updates between existing revision should (and will) always give the same result no matter which ancestor is used. The warning is thus only relevant when doing a "real" merge.

discovery: prevent crash on unknown remote heads with old repo (issue4337) When a remote is not capable of the `branchmap` wireproto command, we denote incoming heads with None. This leads to a crash in the code in charge of displaying the list of unknown remote heads. We now properly detect this case and display a shorter message in this case. The reason for this `set([None])` value is now documented.

obsstore.create: add a simple safeguard against cyclic markers We detect when there is a cycle in the marker itself (precursors being listed as successors).

debugobsolete: catch ValueError that may be raised by obsstore.create There are already a couple of errors that obsstore.create can raise and we are going to introduce a cycle check too.

check-code: extend try/except/finally check for multiple except clauses

repoview: fix try/except/finally for py2.4

test-run-tests: fix up slash/backslash on diff chunks for Windows

test-largefiles: add test for hg log --follow --patch with path This was the one case for test-largefiles that was not broken.

largefiles: don't override matchandpats for always matchers (issue4334) This makes hg log --follow --patch work, since in cmdutil._makelogrevset we use the non-follow matcher for hg log --follow --patch with no file arguments.

largefiles: in overridelog, use non-lf matcher for patch generation (issue4334) This has actually been broken since at least Mercurial 2.8 -- hg log --patch with largefiles only used to work when no largefiles existed. Rev 5809d62e7106 exposed this bug for all cases.

largefiles: drop setting lfstatus in overridelog (issue4334) lfstatus should only be True for operations where we want standins to be printed out. We explicitly do not want that for historical operations like log. Other historical operations like hg diff -r A -r B don't print out standins either. This is required to fix issue4334, but doesn't fix anything by itself. That's why there aren't any tests accompanying this patch.

cmdutil: add a hook for making custom non-follow log file matchers This will be used by largefiles (and basically only by largefiles) in an upcoming patch.

cmdutil: rename _makelogfilematcher to _makefollowlogfilematcher We're going to add a _makenofollowlogfilematcher in an upcoming patch.
