debugbuilddag: read DAG from stdin if not given on cmdline

run-tests: remove check on --shell argument No shell is needed when executing Python tests and finding a good shell might be difficult/impossible on some platforms (e.g., Windows).

subrepo: create subrepos using clone instead of pull Subrepositories used to be created empty and then filled with data using pull. This is wasteful when you do a clone from a local source since it means that no hardlinks are created for the subrepos. This patch make the hgsubrepo._get method check for an empty subrepo and in that case do a clone instead of a pull. This brings in the same data as before, but creates hardlinks when possible.

progress: add speed format This is not enabled by default, but the user can add it by setting progress.format. We might want to let the estimate format output a speed instead of an ETA if there is not total. Currently estimate just returns the empty string in that case.

revlog: support writing generaldelta revlogs With generaldelta switched on, deltas are always computed against the first parent when adding revisions. This is done regardless of what revision the incoming bundle, if any, is deltaed against. The exact delta building strategy is subject to change, but this will not affect compatibility. Generaldelta is switched off by default.

check-code: complain about set.isdisjoint

fix bookmarks rollback behavior Before this patch undo.bookmarks was created on bookmarks write and not with other transaction-related files. There were two issues: first is that if you have changed bookmarks few times after a transaction happened, rollback will give you a state which can point to non-existing revision. Second is that if you have not changed bookmarks after a transaction, rollback will touch your state anyway. This change also adds `localrepo._writejournal` method, which can be used by other extensions to save their transaction-related backup in right time.

record: unconditionally update the working dir after patching

mq: explicitly updatedir() even if patch() fails It already works that way in practice, and we intend to merge updatedir() into patch().

mq: allow to qpop/push with a dirty working copy (issue2780) It's safe to do so if the sets of changed files in the working copy and patches are disjoint.

patch: introduce changedfiles returns the set of all changed files in a given patch

debugindex: change output for generaldelta revlogs For generaldelta revlogs, reporting the deltaparent instead of the chain base makes more sense, since that's what's actually stored in the revlog.

revlog: support reading generaldelta revlogs Generaldelta is a new revlog global flag. When it's turned on, the base field of each revision entry holds the deltaparent instead of the base revision of the current delta chain. This allows for great potential flexibility when generating deltas, as any revision can serve as deltaparent. Previously, the deltaparent for revision r was hardcoded to be r - 1. The base revision of the delta chain can still be accessed as before, since it is now computed in an iterative fashion, following the deltaparents backwards.

revlog: calculate base revisions iteratively This is in preparation for generaldelta, where the revlog entry base field is reinterpreted as the deltaparent. For that reason we also rename the base function to chainbase. Without generaldelta, performance is unaffected, but generaldelta will suffer from this in _addrevision, since delta chains will be walked repeatedly. A cache has been added to eliminate this problem completely.

revlog: remove the last bits of punched/shallow Most of it was removed in e7483ec3c374, but a few pieces were accidentally left behind.

util: make readfile() operate in binary mode writefile() and appendfile() are already working that way.

cmdutil: normalize log message eols when reading from file This will be necessary once util.readfile() operates in binary mode. While changelog.add() already normalizes the message, doing so in logmessage() is required as ui.edit() or others expect messages with LF only.

match: make 'listfile:' split on LF and CRLF We want util.readfile() to operate in binary mode, so EOLs have to be handled correctly depending on the platform. It seems both easier and more convenient to treat LF and CRLF the same way on all platforms.

progress: remove useless statement left by bab267e7fc1a

debugbuilddag: simplify tags serialization a bit

httprepo: send 100-continue on POSTs if using http2

url: use new http support if requested by the user The new http library is wired in via an extra module (httpconnection.py), as it requires similar but different plumbing to connect the library to Mercurial's internals and urllib2. Eventualy we should be able to remove all of keepalive.py and its associated tangle in url.py and replace it all with the code in httpconnection.py. To use the new library, set 'ui.usehttp2' to true. The underlying http library uses the logging module liberally, so if things break you can use 'ui.http2debuglevel' to set the log level to INFO or DEBUG to get that logging information (for example, ui.http2debuglevel=info.)

Import new http library as mercurial.httpclient. This is revision a4229f13c374 of http://py-nonblocking-http.googlecode.com/ with a no-check-code comment added to the end of each file using `for fi in $(hg manifest | grep mercurial/httpclient/) ; echo '# no-check-code' >> $fi`.

rename path_auditor to pathauditor The Mercurial 1.9 release is moving a lot of stuff around anyway and we are already moving path_auditor from util.py to scmutil.py for that release. So this seems like a good opportunity to do such a rename. It also strengthens the current project policy to avoid underbars in names.

revlog: use real Booleans instead of 0/1 in nodesbetween

patch: fix clash between local variable and exception instance The local err variable would be bound to PatchError thrown and it keeps this value even after the except block is executed. The whole thing worked anyway since the rejected variable is set in the except block and this makes the function return -1 when a PatchError is thrown.

subrepo: use code from 71ea5b2b9517 only if Python needs it (issue2795) With Python >= 2.6 the original code already works correct, therefore the fix for issue2556 on Python <= 2.5 broke relative subrepositories with newer versions of Python.

sslutil: extracted ssl methods from httpsconnection in url.py This makes it easier to share ssl cert validation with other http implementations.

check-code: fix checking for sh style in .t tests Restore checks after they were disabled by 64de9ca66511.

run-tests: add --shell command line flag This makes it easy to test with, say, both /bin/bash and /bin/dash instead of changing the system-wide /bin/sh.

run-tests: use type of default to convert environment variable Before, defaults could only be integers, they can now also be strings, floats and what have you.

test-treediscovery: fix escaping for both dash and bash A '\n' on the command line is turned into a newline by dash, but kept as-is by bash, which resulted in a syntax error in the config file. Luckily, dash wont turn '\n' into a newline when it is part of a here-doc, so we can write the config file using that technique.

treediscovery: fix regression when run against older repos (issue2793) I ran the entire test suite with "known" and "getbundle" disabled in localrepository. This generated failures because the old findoutgoing had always queried remote's heads explicitly and thus always got them back in the returned heads. treediscovery.findcommonincoming now correctly returns remote's heads in all cases. Also adds a dedicated test for running treediscovery against a pre-getbundle HTTP server.

For debugindex it is expected to still work, but I changed them as well for consistency.

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.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").

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/

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.

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.

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'.

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

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 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.

remove unused imports and variables

Zeroconf: catch both ValueError and KeyError in get() This prevents a traceback during discovery of available hosts.

run-tests: print a new line before writing the diff

revsets: add a last function last(set, n) = reverser(limit(reverse(set), n))

bundle: more comments about the different header types, remove useless if

hgweb: initialize permhooks at definition time This is simpler than creating it empty and then appending the default checkauthz hook 50 lines below.

revset: fix undefined name ParseError

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.

drop {short,hex}(ctx.node()) calls in favor of ctx methods

mq: add '.' and '..' to list of forbidden patch names When an empty string is being passed to normname it would return '.' causing checkfile() to always return that a patch with that name exists.

subrepo: handle svn tracked/unknown directory collisions This happens more often than expected. Say you have an svn subrepository with python code. Python would have generated unknown .pyc files. Now, you rebase this setup on a revision where a directory containing python code does not exist. Subversion is first asked to remove this directory when updating, but will not because it contains untracked items. Then it will have to bring back the directory after the merge but will fail because it now collides with an untracked directory. Using --force is not very elegant and only works with svn >= 1.5 but the only alternative I can think of is to write our own purge command for subversion.

subrepo: backout bcc6ed0f6c3b

wireproto: add test for new optional arg missing on server New argument is silently ignored by both HTTP and SSH servers. This means we can, for instance, add new flags to getbundle() to request advanced features (like lightweight-copy-aware bundles), and older servers will silently ignore this request and send back a plain bundle.

web: Made elapsed time calculation dynamic (javascript). This allow safe caching of the pages by the browser and still display the right amount of elapsed time upon page refresh. If javascript is disabled, absolute time is displayed, leaving it readable. All the templates have been updated.

extdiff: add repository root as a variable Some external diff tools (notably Plan 9 diff(1)) require the absolute path to the file being diffed for proper function. A root variable was added to inform an external tool of the repository root (the tool is invoked with the cwd set to tmproot).

help: move hgignore man page into built-in help (issue2769)

graphlog: make use of graphmod's revset support

graphmod: use revsets internally Thanks for the idea and most of the implementation to Klaus Koch Backs revisions() and filerevs() with DAG walker which can iterate through arbitrary list of revisions instead of strict one by one iteration from start to stop. When a gap occurs in a revisions (i.e. in file log), the next topological parent within the revset is searched and the connection to it is printed in the ascii graph. File graph can draw sometimes more connections than previous version, because graph is produced according to the revset, not according to a file's filelog. In case the graph contains several branches where the left parent is null, the graphs for each are printed sequentially, not in parallel as it was a case earlier (see for example the graph for README in hg-dev).

svn subrepo: attempt work around obstructed checkouts (issue2752) It should be possible to do better than this with 'svn switch', but the logic required woud be significantly more complex. Until someone needs the performance improvements of using switch, we'll just use the same strategy for everything.

churn: strip key earlier to avoid false negative seach in aliases

bookmarks: further restrict IOError on write This won't risk losing the undo file when the error was something other than file not found

tags: loosen IOError filtering when reading localtags

run-tests: don't count test as succeeded if it failed regressed around ec4ae5727f07

changegroup: do not count closed new heads (issue2697) If a closed head gets pulled, we currently see (example): $ hg pull pulling from $TESTTMP/repo2 searching for changes adding changesets adding manifests adding file changes added 2 changesets with 1 changes to 1 files (+1 heads) (run 'hg heads' to see heads, 'hg merge' to merge) A subsequent 'hg heads' doesn't show that head because it is closed. This patch improves the UI response texts for that same use case to: $ hg pull pulling from $TESTTMP/repo2 searching for changes adding changesets adding manifests adding file changes added 2 changesets with 1 changes to 1 files (run 'hg update' to get a working copy) That is, the part "(+1 heads)" is not shown in that case any longer.

shrink-revlog: defend against null first parents

test-contrib: add a test for shrink-revlog We only verify the extension runs and that verify passes at the end as constructing a test repository that would result in a shrink would be nontrivial.

Move test-dumprevlog to test-contrib in anticipation of more contrib tests
