mq: strip extra whitespace from node ids in header (issue2790) This makes `hg qpush --exact` work with patches created by `hg export`.

check-code: disallow calling opener(...).read() and opener(..).write()

prevent transient leaks of file handle by using new helper functions These leaks may occur in environments that don't employ a reference counting GC, i.e. PyPy. This implies: - changing opener(...).read() calls to opener.read(...) - changing opener(...).write() calls to opener.write(...) - changing open(...).read(...) to util.readfile(...) - changing open(...).write(...) to util.writefile(...)

util & scmutil: adapt read/write helpers as request by mpm

store: use a subclass, not a function for fncacheopener

util.termwidth: never return 0 for terminal width Catch a case where the termwidth was being reported as 0 when I was connecting with TLMTask instead of NSTask in OSX. This caused the progress extension to print no progress. The termwidth should never return 0 so in case we would return 0, simply fall back to the default termwidth below which is 80.

discovery: add new set-based discovery Adds a new discovery method based on repeatedly sampling the still undecided subset of the local node graph to determine the set of nodes common to both the client and the server. For small differences between client and server, it uses about the same or slightly fewer roundtrips than the old tree-based discovery. For larger differences, it typically reduces the number of roundtrips drastically (from 150 to 4, for instance). The old discovery code now lives in treediscovery.py, the new code is in setdiscovery.py. Still missing is a hook for extensions to contribute nodes to the initial sample. For instance, Augie's remotebranches could contribute the last known state of the server's heads. Credits for the actual sampler and computing common heads instead of bases go to Benoit Boissinot.

debugbuilddag: use memctx for speed This drops the options to run arbitrary shell commands within commits and the option to create a file that gets appended to in every revision. It now supports to not write file data at all, which is very fast for generating a pure 00changelog.i (useful for discovery tests, for instance). Timings for 1000 linear nodes: * Old `hg debugbuilddag -o '+1000'` took 4.5 secs. * New `hg debugbuilddag -o '+1000'` takes 2 secs. * New `hg debugbuilddag '+1000'` takes 0.8 secs. (The last one creates only 00changelog.i).

localrepo: reuse parent manifest in commitctx if no files have changed This speeds up the in-memory version of debugbuilddag that I'm working on considerably for the case where we want to build just a 00changelog.i (for discovery tests, for instance). There are a couple of test changes because node ids in tests have changed. The changes to the patch names in test-mq-qdelete.t were required because they could collide with nodeid abbreviations and newly actually do (patch "c" collides with id "cafe..." for patch "b").

bundlerepo: fix and improve getremotechanges Fixes the regression where incoming could show local changes introduced by rev 72c84f24b420.

revset: avoid over-aggresive optimizations of non-filtering functions (issue2549) When limit, last, min and max were evaluated they worked on a reduced set in the wrong way. Now they work on an unrestricted set (the whole repo) and get limited later on.

convert: handle invalid subversion source paths

convert: also catch missing revlogs when introduced in repo roots The previous behaviour was almost as if convert.hg.ignoreerrors was always set for revisions without parents, except that errors were silently ignored. Revlog errors are handled as a side effect of getcopies(), but getcopies() was only called when convert.hg.ignoreerrors was set. Now we always call self.getcopies for root revisions, not only when convert.hg.ignoreerrors is set, just like we do on all other revisions. The extra call might be a bit expensive, but the proper fix for that would be to catch these errors in another way.

status: remove unreachable code for status between revisions The manifest value of a file will never be false when "not parentworking", and the expensive content comparision would thus fortunately never be reached. (If it was reached it would be wrong for example in case of renames.) This code once handled status against working directory, but that has been done elsewhere for a long time.

httprepo: proper handling of invalid responses without content-type (issue2019) This can currently be tested on http://sf.net/

httprepo: use the original exception after falling back to static-http failed Before the fine exception handling in httprepo was never shown. The static-http exception will now only be shown when static-http is requested explicitly.

check-code: adding debug flag

run-tests: add flag to provide extra hgrc options for test runs

graphlog: always sort revisions topologically The grapher cannot really handled revisions if they are not emitted in topological order. The previous 'reverse()' revset was not enough to achieve that and was replaced by an explicit sort call for simplicity. The --limit option is now also handled as usual with cmdutil.loglimit() instead of a 'limit' revset.

graphlog: take the union of --rev specs instead of the intersection

graphmod: correctly emit nodes with more than 2 predecessors The grandparent() function was returning only the closest predecessor of a missing parent while it must return all of them to display a correct ancestry graph.

graphlog: display nodes with more than 2 predecessors While nodes with more than 2 parents do not exist in revision graphs, they do appear when you transform them by removing subgraphs while trying to preserve ancestry links. This code was borrowed from Peter Arrenbrecht <peter.arrenbrecht@gmail.com> pbranch extension.

context: provide an efficient iterator for workingctx This avoids needing to call status or build a synthetic manifest.

tests: export patches only once in test-impexp-branch

tests: do not export several times the same patch/diff in test-import

tests: move rebase-keep-branch into rebase-named-branches It's not worth building a repository just to test keep branch when we can do it our bigger, other, already built repositories.

tests: move testcase from rebase-named-branches to rebase-parameters It saves us a clone of a repository.

tests: change test-rebase-parameters to use bundle/rebase.hg

tests: simplify test-rebase-named-branches We were cloning a repo to perform a smoke test that could have been performed earlier.

tests: upgrade bundles/rebase.hg to support test-rebase-collapse Add two changesets to the scenario so that the bundle can be reused within three tests. Before: @ 5: 'F' | | o 4: 'E' |/| o | 3: 'D | | | o 2: 'C' |/ | o 1: 'B' |/ o 0: 'A' After: @ 7: 'H' | | o 6: 'G' |/| o | 5: 'F' | | | o 4: 'E' |/ | o 3: 'D' | | | o 2: 'C' | | | o 1: 'B' |/ o 0: 'A' Revisions 0-1 keep the same number/label. Others were translated by an offset of 2 (2.C -> 4.E)

tests: introduce a rebase bundle to use with rebase tests Allows saving a few seconds in test runs by not constructing over and over the same repository.

zeroconf: notify the Zeroconf threads when hg exits Zeroconf launches two threads in the background, and they wait on Condition objects to exit. We need to call Zeroconf.close() to release those conditions so that threads can gracefully exit. This means that an interrupt on the hg process will now gracefully propagate to the Zeroconf children, fixing that bug which did not allow us to kill an `hg serve` process.

color: use ui.formatted() to test TTYness, not sys.stdout.isatty() This fixes the color extension not working with pager (broken in 877390020477). The pager extension already sets ui.formatted=True to allow this use case.

pushkey: add hooks for pushkey/listkeys

test-patchbomb.t: clean up progress tests

util: really drop size from readfile

util: add readfile() & writefile() helper functions These two functions allow quickly reading or writing a file, without relying on reference counting to close the file handle afterwards.

revset aliases

opener: add read & write utility methods The two new methods are useful for quickly opening a file for reading or writing. Unlike 'opener(...).read()', they ensure they the file is immediately closed without relying on CPython reference counting.

dispatch: handle IndexErrors

color: verify stdout is a tty before using curses Without this change, curses complains when invoked in certain contexts because stdout isn't a tty (such as emacs integration) but we ask it to check for various bits of information from terminfo.

http: minor tweaks to long arg handling x-arg -> x-hgarg replace itertools.count(1)

httprepo: long arguments support (issue2126) Send the command arguments in the HTTP headers. The command is still part of the URL. If the server does not have the 'httpheader' capability, the client will send the command arguments in the URL as it did previously. Web servers typically allow more data to be placed within the headers than in the URL, so this approach will: - Avoid HTTP errors due to using a URL that is too large. - Allow Mercurial to implement a more efficient wire protocol. An alternate approach is to send the arguments as part of the request body. This approach has been rejected because it requires the use of POST requests, so it would break any existing configuration that relies on the request type for authentication or caching. Extensibility: - The header size is provided by the server, which makes it possible to introduce an hgrc setting for it. - The client ignores the capability value after the first comma, which allows more information to be included in the future.

store: rename the 'opener' argument to 'openertype' The 'opener' argument wasn't, in fact, an actual opener instance, but rather something expected to return an opener. The normal argument, from localrepository, is the scmutil.opener type; hence 'openertype'.

statichttprepo: make the opener a subclass of abstractopener

add filteropener abstraction for store openers

opener: introduce an abstact superclass of it Currently, this class doesn't do anything useful.

graphlog: use a set for inclusion test This makes a big difference in performance in the special case where all revisions are being graphed.

graphmod: restore generator nature of dagwalker 9966c95b8c4f introduced the ability to walk the DAG given arbitrary revisions, but changed the behaviour of it to return a list of all nodes (and create a changectx for each one) rather than doing it lazily. This has a pretty significant impact on performance for large repositories (tested on CPython repo, with output disabled): $ time hg glog real 0m2.642s user 0m2.560s sys 0m0.080s Before 9966c95b8c4f: $ time hg glog real 0m0.143s user 0m0.112s sys 0m0.032s And after this fix: $ time hg glog real 0m0.213s user 0m0.184s sys 0m0.028s

graphlog: log -G --follow file does not work, forbid it We do not have revsets to follow file history.

graphlog: unify log -G revset translation

graphlog: fix log -G --prune follow() revset really means '::.' while we want something based on the passed argument. Also, ancestors() revset does not include the parent revisions.

graphlog: escape log -G single value option arguments

graphlog: fix log -G --removed Current version was mispelled and processed like a valued argument.

graphlog: fix log -G option types when translating to revset For instance, --keyword is a multiple value option while it was processed as a single value option.

revset: add tests for multiple and mixed ^ and ~ operators

extensions: obsolete and remove parentrevspec extension As of 305c97670d7a, revsets implements the ^ and ~ operators that this extension provides, so it's no longer necessary.

wix: a new mercurial.js has replaced graph.js

util.url: copy urllib.unquote() into util to improve startup times The ui class uses util.hasscheme() in a couple of places, causing hg to import urllib even when it doesn't need to. This copies urllib.unquote() to avoid that import. perfstartup time before the URL refactoring (8796fb6af67e): ! wall 0.050692 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) before this change: ! wall 0.064742 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) after this change: ! wall 0.052126 comb 0.000000 user 0.000000 sys 0.000000 (best of 100

url: move URL parsing functions into util to improve startup time The introduction of the new URL parsing code has created a startup time regression. This is mainly due to the use of url.hasscheme() in the ui class. It ends up importing many libraries that the url module requires. This fix helps marginally, but if we can get rid of the urllib import in the URL parser all together, startup time will go back to normal. perfstartup time before the URL refactoring (8796fb6af67e): ! wall 0.050692 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) current startup time (139fb11210bb): ! wall 0.070685 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) after this change: ! wall 0.064667 comb 0.000000 user 0.000000 sys 0.000000 (best of 100)

revlog: introduce _chunkbase to allow filelog to override Used by revlog.revision to retrieve the base-chunk in a delta chain.

filelog: extract metadata parsing and packing _parsemeta returns the dictionary and a list of keys in the order they appear in metadata. This can be used to repack the dictionary in the same order. _packmeta creates metadata from a dictionary and an optional key-order list. In _parsemeta, we use slices and re.search indead of str.index so we can accept both buffers and strings.

discovery: drop findoutgoing and simplify findcommonincoming's api This is a long desired cleanup and paves the way for new discovery. To specify subsets for bundling changes, all code should use the heads of the desired subset ("heads") and the heads of the common subset ("common") to be excluded from the bundled set. These can be used revlog.findmissing instead of revlog.nodesbetween. This fixes an actual bug exposed by the change in test-bundle-r.t where we try to bundle a changeset while specifying that said changeset is to be assumed already present in the target. This used to still bundle the changeset. It no longer does. This is similar to the bugs fixed by the recent switch to heads/common for incoming/pull.

revset: add missing whitespace

url: remove unused/obsolete functions

revset: add ^ and ~ operators from parentrevspec extension ^ (Nth parent) and ~ (Nth first ancestor) are infix operators that match certain ancestors of the set: set^0 the set set^1 (also available as set^) the first parent of every changeset in set set^2 the second parent of every changeset in set set~0 the set set~1 the first ancestor (i.e. the first parent) of every changeset in set set~2 the second ancestor (i.e. first parent of first parent) of every changeset in set set~N the Nth ancestor (following first parents only) of every changeset in set; set~N is equivalent to set^1^1..., with ^1 repeated N times.

encoding: add an encoding-aware lower function

add: notify when adding a file that would cause a case-folding collision On a case-sensitive file system, files can be added with names that differ only in case (a "case collision"). This would cause an error on case-insensitive filesystems. A warning or error is now given for such collisions, depending on the value of ui.portablefilenames ('warn', 'abort', or 'ignore'): $ touch file File $ hg add --config ui.portablefilenames=abort File abort: possible case-folding collision for File $ hg add File warning: possible case-folding collision for File

scmutil: refactor ui.portablefilenames processing The ui.portablefilenames config handling is generally useful for notifying the user of various portability problems.

pure bdiff: don't use a generator Generators are slow, and currently defeat the PyPy JIT.

pure mpatch: avoid using list.insert(0, ...) In Python lists are implemented as arrays with overallocation. As a result, list.insert(0, ...) is O(n), whereas list.append() has an amortised running time of O(1). Reversing the internal representation of the list should cause a slight speedup for pure Python builds.

branchcache: improve speed relative to the amount of heads Updating the branch cache is quadratic to the amount of heads in the repository. One consequence of this was that cloning a pathological repository with 10,000 heads (and nothing else) took hours of CPU time. This patch makes one of the inner loop much faster, by removing a changectx instantiation, and removes another entirely in cases where there are no candidate branch heads which descend from other branch heads.
