histedit: add checkunfinished support (issue3955) The tests contain a couple corner cases where workarounds are now required. Strictly speaking, these are behavior regressions, but of an extremely obscure and marginal sort. Commits or updates in the middle of a histedit would have almost always been fairly serious user error.

rebase: add checkunfinished support (issue3955)

rebase: reorder parent check and state storage This could cause a rebase to be 'in progress' even though it aborted.

commands: add checks for unfinished operations (issue3955) commands checked: backout bisect commit graft import

update: clear any clearable unfinished operations (issue3955) Unclearable operations will cause an abort.

cmdutil: core functionality to block during multistep commands (issue3955) This adds a registration point and check functions that will allow commands to check if multistep operations like an interrupted graft or rebase are in progress before proceeding.

histedit: refuse to edit history that contains merges (issue3962)

largefiles: overridematch() should replace the file path instead of extending (issue3934)

revlog: handle hidden revs in _partialmatch (issue3979) Looking up hidden prefixes could cause a no node exception Looking up unique non-hidden prefixes could be ambiguous

fileset: handle underbar in symbols This was documented, but not implemented.

heads: modernize documentation (issue3992) The old docs emphasized topological heads rather than branch heads and incorrectly defined branch heads as not having children rather than descendants.

convert: catch empty origpaths in svn gettags (issue3941)

template: fix tabindent docstring (issue2880)

merge default into stable for 2.7 code freeze

osutil: consider WindowsError's behaviour to support python 2.4 on Windows This change treat the ESRCH error as ENOENT like WindowsError class does in python 2.5 or later. Without this change, some try..execpt code which expects errno is ENOENT may fail. Actually hg command does not work with python 2.4 on Windows. CreateFile() will fail with error code ESRCH when parent directory of specified path is not exist, or ENOENT when parent directory exist but file is not exist. Two errors are same in the mean of "file is not exist". So WindowsError class treats error code ESRCH as ENOENT in python 2.5 or later, but python 2.4 does not. Actual results with python 2.4: >>> errno.ENOENT 2 >>> errno.ESRCH 3 >>> WindowsError(3, 'msg').errno 3 >>> WindowsError(3, 'msg').args (3, 'msg') And with python 2.5 (or later): >>> errno.ENOENT 2 >>> errno.ESRCH 3 >>> WindowsError(3, 'msg').errno 2 >>> WindowsError(3, 'msg').args (3, 'msg') Note that there is no need to fix osutil.c because it never be used with python 2.4.

churn: split email aliases from the right This splits churn email aliases from the right, to enable incorrectly-specified addresses that include equal signs to be mapped to correct addresses. This will enable aliasing of bad addresses (typically typos) such as: sername=myusername that appear in the churn output through a churn alias such as: sername=myusername = myusername whereas previously splitting from the left would not enable this behavior.

hgweb: highlight line which is linked to at annotate view

hgweb: always start log with searched revision This makes the specified revision be always on top of the list. Before the patch, for example with repo having revisions 0, 1, 2, 3 and user searching for '2', all revisions were shown and the specified one wasn't the first.

util: check if re2 works before using it (issue 3964)

run-tests: backout 4f32747879d1 line endings change It made the windows buildbot sad.

hgweb: highlight line which is linked to at comparison view

hgweb: change highlighted line color to be different from 'inserted' color This changes line highlight color from a fain yellow (#ffff99) to a faint blue (#bfdfff), because yellow color is used in comparison view for inserted lines. This new color is okay for people with different forms of color blindness (tested with a simulator): a) this color looks quite different from other used backgrounds b) text doesn't lose distinction on this color

convert: fix bad conversion of copies when hg.startrev is specified The 'copynode' was looked up in self.keep as if it was a changeset node. It is however a filelog node, and self.keep would thus fail if it actually looked at its parameter ... which it only did if a startrev was specified. Instead we now don't check the copy node - we don't have to. It must have been copied from one of the parents, and we already check whether one of the parents have the copy source. We could perhaps use linkrev to see if the corresponding changeset was converted ... but that would sometimes be wrong. The existing test of this was wrong - now it is better, but it seems like it exposes a 'log' issue.

test-convert-hg-startrev: fix test for copy removal on missing parent The test assumed that 'b' was missing just because the changeset that introduced 'b' wasn't converted ... but 'b' was also not removed before the start revision, and the parent was thus not missing at all. Instead we introduce a file 'f' in rev 0 and remove it in rev 1 so the copy source really doesn't exist in the repo that is converted from rev 1.
