branchmap: check node against changelog instead of repo Testing 'node in repo' requires constructing a changectx, which is a little expensive. Testing 'repo.changelog.hasnode(node)' is notably faster. This saves 10-20ms off of every command, when testing a few thousand nodes from the branch cache. I considered changing the implementation of localrepository.__contains__ so every place would benefit from the change, but since localrepository.__contains__ uses changectx to check if the commit exists, it means it supports a wider range of possible inputs (like revs, hashes, '.', etc), so it seemed unnecessarily risky.

changegroup: clear progress callback after changelog processing The progress callback is replaced by one for manifests after changelog processing is done, but let's not depend on manifests replacing the value and instead explicitly clear it.

tests: adjust for code move in Hypothesis 2.0.0 It appears that the Settings class was renamed to settings, and because of this, the settings module was renamed to configuration. https://github.com/DRMacIver/hypothesis/commit/a0e663b

changegroup: progress for added files is not measured in "chunks" The "prog" class cg1unpacker.apply() has the unit set to "chunks". This is not correct for files, where the file itself is the unit. The unit is not usually printed, which is probably why this has not been fixed yet. It can be show with e.g. "--config progress.format='topic number unit'".

changegroup: exclude submanifests from manifest progress The progress callback for manifests is cleared outside of _unpackmanifests(), which means it will remain in effect while pulling subdirectory manifests when using treemanifests. Since the total number of revisions used for the progress is the number of changesets, the total number of treemanifest revisions is usually larger than that. One effect of this is that the ETA is negative. It's hard to estimate the number of subdirectory revisions, so let's just exclude them from progress for now.

commit: block amend while histedit is in progress (issue4800)

chg: limit reconnect attempts Some users may have hg as a wrapper script which sets sensitive environment variables (like setting up virtualenv). This will make chg redirect forever because the environment variables are never considered up to date. This patch adds a limit (10) for reconnect attempts and warn the user with a possible solution if the limit is exceeded.

chg: use validate to make sure the server is up to date This patch uses the newly added validate method to make sure the server has loaded the up-to-date config and extensions. If the server cannot validate itself, the client will receive instructions and follow them to try to reach another server that is more likely to validate itself. The instructions can be a redirect (connect to another server address) and/or an unlink (stops an out-dated server).

chg: implement validate in hgclient This patch implements the corresponding validate method in hgclient. It will return instruction strings as is without taking any real action.

hgclient: use absolute_import and print_function

fixpax: use absolute_import and print_function

debugcmdserver: use absolute_import and print_function

check-config: use absolute_import and print_function

casesmash: use absolute_import

chgserver: implement validate command validate will load the repo config and check if the server has up-to-date config to continue serve the client. In case it does not, the server will send instructions to the client about what to do next, including to retry with a different address or to unlink an outdated socket file to stop an old server.

templater: handle exception when applying map operator to non-iterable object Before this, "{noniterable % template}" raised an exception. This tries to provide a better indication for the common case, where a left-hand-side expression is a keyword.

templater: factor out thin helper that evaluates argument as string This function is trivial, but it can make it clear that args[i] is a (func, data) pair.

color: make label() template function stringify "expr" argument first Since label() should return a string (or a thunk to be evaluated to a string), this change is okay. This helps porting to evalstring() helper. See the next patch for details.

templater: fix shortest() to evaluate int argument and handle error

templater: fix pad() to evaluate int argument and handle error

templater: drop redundant type conversion when evaluating integer argument A function argument may be an integer. In this case, it isn't necessary to convert a value to string and back to integer. Because an argument may be an arbitrary object (e.g. date tuple), TypeError should be caught as well.

templater: factor out function that evaluates argument as integer We have more bare int()s that may raise ValueError or TypeError. This function will be used to fix them.

chgserver: use basename for socket symlink Previously we use full path and the symlink may point to outside (unsafe) world if the directory is moved. This patch fixes it by only linking to basename of the target. Therefore the symbolic link and socket files will always stay in the same directory.

patch: when importing from email, RFC2047-decode From/Subject headers Reported at https://bugs.debian.org/737498

histedit: reword message when a changeset produces no changes There are various ways to use histedit such that an item in the list of things to perform will not result in a change relative to the previous repository state. When that happens, histedit does not keep the commit/message. This changes the note to try to explain to the user that it will not be present in their history.

tests: replace cat.py with cat in test-histedit-fold-non-commute.t

tests: Solaris grep doesn't add a trailing newline when it's missing The bad-extension tests emits a list of not-loaded extensions, and pipes that output through grep. On Solaris, the test-output gets "(no-eol)" appended because although the message has no trailing newline, GNU grep adds it. If we simply add the newline to the message, the problem goes away for both versions of grep.
