rebase: improve description of --base No Mercurial DAG has ever (!) been drawn in a way where 'up to' would apply. Instead, describe deliberatey vague and informal instead of seemingly precise but not describing the essentials: rebase the tree around the specified changeset without ancestors of dest

dagutils: fix docstrings for singleton internalize/externalize

cmdutil: avoid the confusing name 'patch' for a matcher

fedora: remove sample.hgrc from shipped files sample.hgrc was long obsolete and was removed in 63ed188e3fc7.

config: propose some sample global config file An example of what could be suggested to the user as a global config file. Trying to be conservative here, and only suggesting the safest possible extensions. In addition to the user-level extensions, the blackbox extension is something a sysadmin might reasonable want to enable for every repo on the system.

config: give more fine-tuned sample hgrcs to this command The hgrc for user config is typically different from the hgrc at the system-wide or repository level. This patch provides different sample hgrcs for each level. Sometimes when copying repos around, the copy or the original don't have a default path yet, so at least for `hg config -l`, this ought to provide a more reasonable default and suggestions of what typically goes there. The actual sample configs go in the config.py file, to minimise clutter. In order to avoid an unnecessary import, the corresponding import for this dictionary is at the file level.

rebase: add a deprecated -i/--interactive flag A common mistake can be to type 'hg rebase -i' to discover interactive history editing. We add a -i/--interactive flag as discussed in the sprint and deprecate it right away, but hint people using it to use histedit instead.

revlog: introduce isancestor method for efficiently determining node lineage Hide the not so obvious use of commonancestorsheads.

clone: provide sample username = config entry in .hg/hgrc (issue4359) Some users clone from a server before ever running 'hg config --edit', so they don't see our helpful template for things like enabling the username. Attempt to give them some helpful guidance.

test-acl: alter sed construct to avoid changes in .hg/hgrc formatting A future patch is going to add some extra commented-out boilerplate to the top of .hg/hgrc during clone. In order to make this test not require regular updates, switch to searching for [hooks] or [acl] and print file from the first match to that pattern.

dispatch: check shell alias again after loading extensions (issue4355) Before this patch, the shell alias causes failure when it takes its specific (= unknown for "hg") options in the command line, because "_parse()" can't accept them. This is the regression introduced by 03d345da0579. It fixed the issue that ambiguity between shell aliases and commands defined by extensions was ignored. But it also caused that ambiguous shell alias is handled in "_parse()" even if it takes specific options in the command line. To avoid such failure, this patch checks shell alias again after loading extensions. All aliases and commands (including ones defined by extensions) are completely defined before the 2nd (= newly added in this patch) "_checkshellalias()" invocation, and "cmdutil.findcmd(strict=False)" can detect ambiguity between them correctly. For efficiency, this patch does: - omit the 2nd "_checkshellalias()" invocation if "[ui] strict= True" it causes "cmdutil.findcmd(strict=True)", of which result should be equal to one of the 1st invocation before adding aliases - avoid removing the 1st "_checkshellalias()" invocation it causes "cmdutil.findcmd(strict=True)" invocation preventing shell alias execution from loading extensions uselessly

dispatch: make "_checkshellalias" reusable regardless of adding aliases To reduce changes in the subsequent patch fixing issue4355, this patch makes "_checkshellalias" reusable regardless of adding aliases. In this patch, alias definitions are added and restored, only when "precheck=True".

build: don't clean __version__.py on 'make clean' in release tarballs When running 'make clean' in an extracted release tarball, file mercurial/__version__.py is removed, causing a subsequent install to indicate 'version unknown'. This problem was reported in the past [1] and a patch proposed in that mail, but was never properly sent nor applied. [1] http://selenic.com/pipermail/mercurial/2010-December/036249.html

revert: drop now useless conditional in the backup check Now that we removed the (hopeless) attempt to backup file we knew to be missing in the target changeset, we can stop checking if the file exists in the target changeset.

revert: no backup for `dsadded` set There is only one case where a backup is required in the `dsadded` set, and the current backup mechanism fails to handle it. So we stop trying to do backups at all for now. This will help us to simplify the backup code and finally fix this backup issue.

revert: add more padding in the dispatch list We are going to add more sets and some of them will have longer names. We add padding in a standalone patch for readbility purposes.

revert: add documentation in the dispatch table More sets are coming so documenting the existing ones will help.

revert: add a way for external extensions to prefetch file data This allow extensions that mess with the storage layer (remotefilelog, largefile) to prefetch any data that will be accessed during the revert operation. We are currently fetching more data than theoretically required because the backup code is a bit stupid. Future patches will improve that.

histedit: abort gracefully on --continue/--abort with no state Previously we'd print an ugly message saying that the histedit-state file doesn't exist in the repo.

Added signature for changeset 5dc91146f353

Added tag 3.1.1 for changeset 5dc91146f353

bookmarks: allow pushkey if new equals current Previously a bookmark pushkey would be rejected if the specified 'old' value didn't match the servers 'current' value. This change allows this situation, as long as the 'current' server value equals the 'new' pushkey value already. We are trying to write a hook that forces a server bookmark to move forward, using a changegroup hook. If the user also pushed the bookmark, they would get an error, since they computed their pushkey (old,new) pair before the server moved the bookmark. Long term, bundle2 will let us do this more smartly, but this change seems reasonable for now.

tests: improve test coverage of branch command and existing branches

localrepo: make it possible to pass multiple path elements to join and wjoin This makes join and wjoin behave in the same way as os.path.join. That is, it makes it possible to pass more than one path element to them. Note that the first path element is still required, as it was before this patch, and as is the case for os.path.join.

run-tests: make --interactive work with --view

convert: don't use multi-argument set.update Mumble mumble 2.4 mumble.

error: use docstrings, not bare strings, for error classes

osx: create dmg with installer instead of zip OS X would offer to expand the zip so the (multi file) installer inside it could be run ... but that would leave the expanded zip folder around. Instead, use a .dmg file that automatically will be mounted - that seems more common on OS X. Still, there is two levels of levels of clicking before actually launching the installer. Having a single file installer would be better ... but seems to be hard. A more feasible improvement would be some fancy layout inside the .dmg .

branchmap: pre-filter topological heads before ancestors based filtering We know that topological heads will not be ancestors of anything, so we filter them out to potentially reduce the range of the ancestors computation. On a strongly headed repo this gives humble speedup: from 0.1984 to 0.1629

branchmap: issue a single call to `ancestors` for all heads There is no reason to make multiple calls. This provides a massive speedup for repo with a lot of heads. On a strongly headed repo this gives humble speedup in simple case: from 8.1097 to 5.1051 And massive speedup in other case: from 7.8787 to 0.1984

test-ancestor: add a test for `ancestor` with ancestry within the initset I was wondering if revisions in the initial set that are still ancestors of other elements in the initial set were yielded by `changelog.ancestors`. I now have my answer (they do) and Mercurial has a new test.

bundle2: pull obsmarkers relevant to the pulled set through bundle2 We use the new `obsheads` argument to retrieve them in a bundle2 part at the same time as the changegroup.

getbundle: add `obsmarkers` argument to getbundle This argument triggers the retrieval of all markers relevant to the set of changesets defined by the nodes in `heads`.

pull: use the "cg" argument when pulling a bundle2 We use the `cg` argument to disable the generation of a changegroup part. This is useful to pull information when changesets are already in sync (phases, obsmarkers).

wireprotocol: fix 'boolean' handling The encoding and decoding code were swapped. This is now fixed.

push: only push obsmarkers relevant to the "pushed subset" We should only exchange obsolete markers related to the changesets that are being exchanged. For example, if `A'` is a successor of `A`, we do not want to push the marker if we are not exchanging `A'`. Otherwise `A` would disappear without a successor, leading to confusion for both users and the evolution mechanism. Therefore we now exchange only the markers relevant to the subset of nodes involved in the push (the nodes themselves may be already common but were selected by --rev (or the lack of --rev)). Note that all selected markers are still exchanged on each push. We do not have a discovery protocol for markers in core yet. Such discovery would save us the exchange of markers known on both side.

test-obsolete: sort the output of debugobsolete The set of relevant markers is currently unordered. Therefore the markers will be added in arbitrary order. We sort the list of markers beforehand to ensure stable output for testing.

test-obsolete: change a marker so it is relevant to the exchanged set We are going to only exchange markers relevant to the exchanged changesets. So we need to change this marker to use a known changeset as a successor instead of a precursor.

push: use bundle2 to push obsmarkers when possible

exchange: add a `buildobsmarkerpart` function We'll have to build an obsmarker part for both push and pull. So we build a function to factor out the common part.

obsolete: add a `commonversion` function This function returns the highest common version between the locally known formats and a list of remotely known formats. This is going to be useful to know what format should be used for exchange.

bundle2: add a `obsmarkersversion` function to extract supported version Right next to the function that encodes the supported versions in capabilities we add a function that decodes the versions out of capabilities. This is going to be useful to know what formats can be used for exchange.

bundle2: advertise the obsmarker part in bundle2 capabilities

bundle2: introduce a `getrepocaps` to retrieve the bundle2 caps of a repo This function lets extensions change the bundle2 capabilities of a repository.

obsmarker: move bundle2caps from the localrepo class to the bundle2 module The localrepo path was quicker, easier, more seductive. We'll soon add a function in another changeset to alter the capabilities.
