largefiles: omit restoring standins if working parent is not rollbacked For efficiency, this patch omits restoring standins and updating lfdirstate, if the parent of the working directory is not rollbacked. This patch adds the test not to confirm whether restoring is skipped or not, but to detect unexpected regression in the future: it is difficult to distinguish between skipping and perfectly restoring.

repoview: fix 0L with pack/unpack for 2.4

help: add pad function to template help Commit aa51392da507 introduced a pad function for use in templates, but did not add the corresponding documentation to 'hg help templating'.

histedit: use str.startswith to check for comments in action list

histedit: drop duplicate line extracting keep option

import: avoid editor invocation when importing with "--exact" for exact-ness Before this patch, external editor is invoked when imported patch has no commit message, even if "--exact" is specified. Then, exact-ness is broken, because empty commit message causes failure of committing. This patch avoids editor invocation at importing with "--exact" for exact-ness, because commit message in the patch should be kept as it is in such case, even if it is empty.

import: disallow meaningless combination of "--exact" and "--edit" Before this patch, "hg import" allows combination of "--exact" and "--edit", even though editing commit message breaks exact-ness. This patch disallows meaningless combination of "--exact" and "--edit".

config: highlight parse error caused by leading spaces (issue3214) Added "unexpected leading whitespace" message to parse error when .hgrc has a line that starts with whitespace. Helps new users unfamiliar with syntax of rc file.

test-config: add tests for invalid syntax This was not tested and there is more to come in the next patch.

debugobsolete: add a --rev argument This argument can be used to list markers relevant to a set of revisions. We add a test for this option and the relevant computation in the same move.

obsolete: rename `allmarkers` to `getmarkers` This function is going to gain a "nodes" argument to filter the markers to the ones relevant to <nodes> only.

debugobsolete: add a way to record parent information We add a ``--record-parents`` flag to debugobsolete. This can be used to record parent information in the marker when the precursors are known locally. This will be useful to test the "relevant markers" computation.

obsstore: add relevantmarkers method We add a ``relevantmarkers`` method to fetch all markers that seem relevant to a set of nodes. See function documentation about how this set is computed. This will let us exchange only the markers that seem "relevant" to the set of changesets related to a push or a pull. The approach used to define "relevant" has been successfully tested in evolve for 6 months.

obsstore: keep track of children information We use the new `parents` field to build a dictionary of markers that touch children of a node. This will be used to link prune markers to a set of exchanged nodes.

push: check if local and remote support evolution during discovery We can now directly prevent any evolution-related operation from happening by using an empty set for outgoing markers. So we detect if no transfers should occur and use an empty set in this case.

obsstore: drop outdated comment This comment was associated with a now-defunct line.

cvsps: add two more tiebreakers in cscmp test-convert-cvs.t has been a little flaky for a while now. Add an extra tiebreaker in cscmp so that all the cases in the test will sort reliably. Without this patch, test-convert-cvs.t failed after 346 runs. With this patch, I stopped trying to get it to fail after 615 runs. While not conclusive, that makes me pretty optimistic that this is a working fix.

annotate: abort early if no file is specified This change is intended to move the getdate function near the opmap table.

purge: avoid full walks when directories aren't purged If match.traversedir is not None, we're forced to do full walks. However when we aren't purging directories we don't need to set match.traversedir to anything. This speeds up non-full walks such as the one hgwatchman makes possible. For mozilla-central with hgwatchman enabled, 'hg purge --files' goes from 0.88 seconds to 0.22.

clone: for local clones, copy over filtered branchcaches as well (issue4286) Local clones copy/hardlink over files directly, so the branchcaches should all be valid. There's a slight chance that a read operation would update one of the branchcaches, but we hold a lock over the source repo so they shouldn't cause an invalid branchcache to be copied over, just a different, valid one.

clone: for local clones, copy branchcache from the right location (issue4286) The unfiltered branchcache is in .hg/cache/branch2, not .hg/store/cache/branch2.

obsolete: avoid 2-argument form of enumerate, which was new in Python 2.6

repoview: use util.sha1() instead of hashlib.sha1() 45b5cd948a4d accidentally broke Python 2.4 compatibility, this fixes it.

debugobsolete: display parents information from markers Now that we have a new field, we need a way to visualize it.

obsmarkers: add a `parentnodes` method to retrieve parent information

obsstore: also store the 'parents' field on disk We now store the `parents` field on disk. We use the same strategy as for `date`: We stick it into the metadata. This is slow and dirty, but this is also the only way we currently have. At some point we'll have a new obsstore format to store this properly.

obsstore: drop 'date' from the metadata dictionary We are extracting the `date` information from the metadata at read time. However, we failed to remove it from the metadata returned in the markers. This is now fixed.

createmarkers: automatically record the parent of pruned changesets We need this information to build the set of relevant markers during exchanges. This can only be done at the `createmarkers` level since the `obsstore.create` function does not have a repo and therefore has no access to the parent information.

obsstore: add a `parents` argument to obsstore.create We need a way to pass the information to the function. Some guru told me that what's arguments are made for.

obsstore: add a `parents` field This field is intended to store the parent of the precursor. This is useful to attach pruned changesets to a set of exchanged changesets. We currently just add the fields with a None value. None stands for "no data recorded".
