run-tests: alternative way of handling \r on Windows After f71d60da58fb all \r was stripped from output on Windows, and the places where a \r explicitly was expected it was accepted that it was missing. Ugly hack. Instead we now accept that an extra \r might appear at the end of lines on Windows. That is more to the point and less ugly.

obsolete: flip `obstore.successors` and `obsolete.precursors` People were confused by the fact `obstore.precursors` contained marker allowing to find "precursors" and vice-versa. This changeset changes their meaning to: - precursors[x] -> set(markers on precursors edges of x) - successors[x] -> set(markers on successors edges of x) Some documentation is added to clarify the situation.

obsolete: add example of marker usage in the documentation Recent discussion with Augie Fackler pointed the lack of such example in the documentation.

obsolete: cheap detection of nullid as successors Nullid as successors create multiple issues: - Nullid revnum is -1, confusing algorithm that use revnum unless you add special handling in all of them. - Nullid confuses "divergent" changeset detection and resolution. As you can't add any successors to Nullid without being in even more troubles Fortunately, there is no good reason to use nullid as a successor. The only sensible meaning of "succeed by nullid" is "dropped" and this meaning is already covered by obsolescence marker with empty successors set. However, letting some nullid successors to slip in may cause terrible damage in such algorithm difficult to debug. So I prefer to perform and clear detection of of such pathological changeset. We could be much smarter by cleaning up nullid successors on the fly but it would be much for expensive. As core Mercurial does not create any such changeset, I think it is fine to just abort when suspicious situation is detected. Earlier experimental version created such changesets, so there are some out there. The evolve extension added the necessary logic to clean up its mess.

commands: don't infer repo for commands like update (issue2748) Maintain a whitelist of commands to infer the repo for instead. The whitelist contains those commands that take file(s) in the working dir as arguments.

hgweb: make the escape filter remove null characters (issue2567)

histedit: create obsolescence markers in deterministic order I arbitrary use the revnum of the precursor because it sound a right order.

bookmarks: when @ bookmark diverges, don't double the @ sign (BC) This changeset treats the bookmark "@" as a special case for the naming of divergent bookmarks, as per the tables below. For the <no alias> case, the actual suffix will vary, depending on what suffixes are already in use. Before: Bookmark | Remote | Divergent Bookmark -------------------------------------- foo | bar | foo@bar foo | <no alias> | foo@1 @ | bar | @@bar @ | <no alias> | @@1 After: Bookmark | Remote | Divergent Bookmark -------------------------------------- foo | bar | foo@bar foo | <no alias> | foo@1 @ | bar | @bar @ | <no alias> | @1 This case is likely to be more common now that 92980a8dfdfe has made the "@" bookmark have special meaning to clone. The change in behavior was discussed on the mailing list in the thread below: http://markmail.org/thread/rwedgxp7le5j2h2f

histedit: max(x, key=y) and min(x, key=y) are not available in python 2.4 Use sorted(x, key=y)[-1] or sorted(x, key=y)[0] instead.

vfs: use self.write to write symlink placeholders The existing write() path is much more robust than the hand-rolled version that was inlined here.

histedit: do not use "min" on ctx It does not crash but does not compare revision number at all. We actually remove any call to min because the list is already topologically sorted.

histedit: clean abort when there is nothing to edit

histedit: rename `revs` in `ctxs` inside the `between` function The variable content is actually contexts, not revision numbers.

test: fix invalid redirection for histedit text Appending to the file is wrong, we want new content.

vfs: backout fchmod change from 76b73ce0ffac Only works on Unix with Python >= 2.6, need a different fix.

histedit: refuse to edit public changeset Public changeset are immutable. This changeset enforce that in histedit.

histedit: ignores hidden revision when checking for orphaned nodes We do not want hidden revision to block histedit. They are already "dead" and we do not care about dead orphans. see similar changeset 9e2dc0d292cd for rebase.

histedit: simplify computation of edited set (issue3620) This complex code can be replaced by two simple revset calls.

histedit: add obsolete support When the obsolete feature is enabled, histedit creates obsolescence marker instead of stripping replaced changesets. For now, we keep stripping temporary nodes created along the way.

histedit: replace various nodes lists with replacement graph (and issue3582) This changeset rewrites the change tracking logic of histedit to record every operation it does. Tracked operations record the full list of "old" node that will eventually be removed to the list of new nodes that replace it. Operations on temporary nodes are tracked too. Dropped changesets are also recorded as an "old" node replacement by nothing. This logic is similar to the obsolescence marker one and will be used for this purpose in later commit. This new logic implies a big amount of change in the histedit code base. histedit action functions now always return a tuple of (new-ctx, [list of rewriting operations]) The old `created`, `replaced` and `tmpnodes` are no longer returned and stored during histedit operation. When such information is necessary it is computed from the replacement graph. This computation is done in the `processreplacement` function. The `replacemap` is also dropped. It is computed at the end of the command from the graph. The `bootstrapcontinue` methods are altered to compute this different kind of information. This new mechanism requires much less information to be written on disk. Note: This changes allows a more accurate bookmark movement. bookmark on dropped changeset are now move of their parent (or replacement of their parent) instead of their children. This fix issue3582

merge with durin42

clone: update to @ bookmark if it exists

templatefilters: avoid traceback caused by bogus date input (issue3344) Wrap datefilters which split date texts with util.parsedate. We do not abort, as the bogus date must have been given by the user.

notify: support revset selection for subscriptions A repo pattern for any notify configuration contains a glob matching the path to the repo. Additionally, it may now contain a revset spec, separated from the glob by '#'. Example: [reposubs] */widgets#branch(release) = qa-team@example.com This sends to ``qa-team@example.com`` whenever a changeset on the ``release`` branch triggers a notification in any repository ending in ``widgets``. This patch was completely done by David Champion <dgc@uchicago.edu> with me making tiny changes to his tests.

revsets: add branchpoint() function The branchpoint() function returns changesets with more than one child. Eventually I would like to be able to see only branch points and merge points in a graphical log to see the topology of the repository.

vfs: use fchmod for _fixfilemode On general principle, we should use fchmod instead of chmod to avoid security pitfalls, although none is likely possible here.

tests: correctly report a test killed by a signal

histedit: update bookmark movement notice New format is: histedit: moving bookmarks <bookmark> from <old> to <new>

histedit: simplify computation of `newchildren` during --continue We are now checking for any changesets between the previous `parentctx` and the current working directory parent. If the current working directory parent is inconsistent, we abort. This change is useful as it simplifies the --continue process, easing upcoming changes. While working on this changeset, I spotted an unhandled corner case. This corner case is now documented and have an appropriate issue in the tracker (issue3655). However, the corner case is still unhandled. handling this test case would required some additional work: - actually decide what the proper behavior should be: - change content of "histedit-state" to add missing data necessary to detect the situation - add proper testcase, But leaving the case unhandled is "okay": - this is not a regression, - this is not the purpose of the current series, - the freeze was near and I had more critical stuff to attend to, - this is a simple but non trivial, (see above)
