templater: catch regexp error at sub() function This patch splits re.sub() into re.compile() and sub() so that it can distinguish which argument causes re.error.

graphmod: compute slow revset query once prior to reachableroots (issue4782) Because revsets query is evaluated lazily, "list(revs)" may take long for complicated query. So we shouldn't iterate revs many times. This patch is the easiest workaround for the issue4782. We could introduce more aggressive caching, but it wouldn't be as fast as the simple baseset operation. Gregory Szorc said "this makes `hg wip` on my Firefox clone ~4x faster than 3.5.1 (~6.5s to ~1.5s). This is after a regression in @ to ~45s."

profiling: add config option for enabling profiling Previously you could only enable profiling via the --profile option. This is awkward when trying to debug a server side operation. Let's add a config option to enable profiling. In the future, this could be extended to allow profiling a certain percentage of operations (and potentially reporting that information to an external service).

blackbox: add pid to output This adds the process id to the line header for the blackbox output. This is useful for distinguishing processes when using the blackbox on a server and many processes are writing to the blackbox at once.

exchange: allow fallbackheads to use lazy set behavior The common ancestor set implementation was made lazy a couple years ago, but this piece of code still required processing the entire repo by putting set() around the lazy set. The code was introduced in 5653f2d166ea, a year before the lazy ancestor set was added. Dropping the set() shaves 3.5 seconds off of 'push -r' in repos with hundreds of thousands of commits.

hgweb: move templater instantiation to requestcontext This code needs to access a lot of config options. All our config lookups have moved to requestcontext. It makes sense to move this function there.

rebase: fix warning about ignoring tool option on rebase continue (issue4698) Before this patch rebase --continue with specified --tool option outputs warnings "tool option will be ignored". It is false statement because in case of any merge conflicts it uses specified tool to resolve it. This patch makes this warning appears only when user specified --tool when running rebase --abort , in this case tool doesn't have any sense

hgweb: create websubtable on requestcontext

hgweb: move templatepath to requestcontext This does change behavior in that the templatepath could change during the lifetime of the server. But everything else can change, I don't see why template paths can't.

hgweb: extract web substitutions table generation to own function It doesn't use any state in hgweb except for the repo instance. Move it to a standalone function.

hgweb: remove hgweb.configbool It is redundant with requestcontext.configbool.

hgweb: move additional state setting outside of refresh We want refresh() to only be about refreshing repository instances. This state doesn't belong in requestcontext because it is shared across multiple threads.

commands: support hg help scripting.HGPLAIN keywords are lowercased within help/minirst...

run-tests: use $HGTEST_RUN_TESTS_PURE test-run-tests and test-hghave call run-tests; if you don't have a working build environment, and you are trying to use --pure, then if they don't use --pure or --with-hg, they'll break.

minirst: don't treat top level item as children of last item (issue4803) test for "hg help -c config" in help config

scmutil.readonlyvfs: implement join Required in an upcoming patch.

localrepo: move dirstate validate function to class scope This will allow the function to be referred to by subclasses, as required for upcoming patches.

convert: remove restriction on multiple --rev in hg source Multiple --rev args on convert is a new feature, and was initially disabled for all sources. It has since been enabled on git sources, and this patch enables it on mercurial sources.

hgweb: use latest mtime for caching tag (issue4814) Previously, we were using the last mtime we saw when reporting the HTTP cache etag. When we added bookmarks to the end of the list of files checked, unchanged or missing bookmarks would keep the client cache from being invalidated.

hgweb: initialize repostate to None The initial value is irrelevant since refresh() compares it to a tuple of tuples of file mtime and size. None != tuple and None is a better default value than a tuple containing irrelevant values.

debian: switch to using debhelper and dh_python2 to build debs This is a much larger commit than I'd like, but I honestly don't see a good way to break it up and leave things working. Summary: We now use debian/rules with debhelper to build our debs. This is much more standard, and means we use dh_python2 to do things like handle leaving .pyc files out of the built debs. The resulting package is split into mercurial and mercurial-common, with the former being the hg stub and all the native .sos, and the latter being basically everything else. builddeb and dockerdeb are updated to use the new system. The old way (using dpkg by hand) breaks with the above changes because debian/control no longer contains a version string (that's now guessed from the phony changelog.) Tests are updated to assert that the right files end up in the right debs.

test-debian-packages: new test for testing construction of debian packages

test-docker-packaging: test packages built using docker For now this only tests debian packages, but it could easily be extended to also test rpms.

hghave: correct test for debhelper debhelper exits with a nonzero status when you pass --help, at least on jessie.

bundle2: don't try to recover from a GeneratorExit (issue4785) GeneratorExit means the other end of the conversation has already stopped listening, so don't try and yield out error information. Instead, just let the GeneratorExit propagate normally. This should resolve esoteric issues observed with servers that have aggressive timeouts waiting for data to send to clients logging internal Python errors[0]. This has been observed with both gunicorn's gevent worker model and with scm-manager's built-in webserver (which itself is something sitting inside jetty.) 0: Exception RuntimeError: 'generator ignored GeneratorExit' in <generator object getchunks at 0x7fd2f6c586e0> ignored

revset: fix resolving strings from a list When using multiple revsets that get optimized into a list (like hg log -r r1235 -r r1237 in hgsubversion), the revset list code was assuming the strings were resolvable via repo[X]. hgsubversion and other extensions override def stringset() to allow processing different revision identifiers (such as r1235 or g<githash>), and there for the _list() implementation was circumventing that resolution. The fix is to just call stringset(). The default implementaiton does the same thing that _list was already doing (namely repo[X]). This has always been broken, but it was recently exposed by 4ee4f7415095 which made "--rev X --rev Y" produce a combined revset "X | Y".

dispatch: error out on invalid -R path even if optionalrepo (issue4805) (BC) Before this patch, repo could be set to None for wrong -R. It's okay for commands that can reject repo=None, but the command server have a problem because: - it accepts repo=None for "unbound" mode - and it reenters dispatch() where repo object is created for cwd by default Test outputs are changed because the error is detected earlier. I think new message is better than ".hg not found".

test-ssh: remove superfluous triple slashes from absolute path test Because pwd should start with "/", "/`pwd`" is enough to make absolute path.

vagrant: update to official Debian 8.1 base box Debian now rolls their own official Vagrant base boxes, so use that. At the same time, we're updating from Debian 7.4 (wheezy) to 8.1 (jessie), and switching from 32-bit to 64-bit (Debian does not provide 32-bit base boxes).

buildrpm: mkdir -p two needed directories (issue4779) Without this, building RPMs can fail.

hghave: use subprocess instead of os.popen os.popen was deprecated in Python 2.6 in favor of subprocess, so let's move into the future.

hgweb: move archive related attributes to requestcontext As part of this, "archive_specs" was renamed to "archivespecs" to align with naming conventions. "archive_specs" didn't technically need to be moved from hgweb. But it seemed to make sense to have all the archive code in the same class. As part of this, hgweb.configlist is no longer used, so it was deleted.

hgweb: move some config options to requestcontext Various config options from the repository were stored on the hgweb instance. While unlikely, there could be race conditions between a new request updating these values and an in-flight request seeing both old and new values, leading to weird results. We move some of options/attributes from hgweb to requestcontext. As part of this, we establish config* helpers on requestcontext. As part of the move, we changed int() casts to configint() calls. The int() usage likely predates the existence of configint(). We also removed config option updating from once every refresh to every request. I don't believe obtaining config options is expensive enough to warrant only doing when the repository has changed. The excessive use of object.__setattr__ is unfortunate. But it will eventually disappear once the proxy is no longer necessary.

hgweb: establish class for holding per request context Currently, hgweb applications have many instance variables holding mutated state. This is somewhat problematic because multiple threads may race accessing or changing this state. This patch starts a series that will add more thread safety to hgweb applications. It will do this by moving mutated state out of hgweb and into per-request instances of the newly established "requestcontext" class. Our new class currently behaves like a proxy to hgweb instances. This should change once all state is captured in it instead of hgweb. The effectiveness of this proxy is demonstrated by passing instances of it - not hgweb instances/self - to various functions.

hgweb: don't make request optional The "request" argument has been optional in this code since it was introduced in 38170eeed18c in 2009. There are no consumers that don't pass this argument. So don't make it an optional argument.

hgweb: add some documentation It took longer than I wanted to grok how the various parts of hgweb worked. So I added some class and method documentation to help whoever hacks on this next.

hgweb: limit branches shown on summary page to 10 Tags and bookmarks on summary page are already limited to 10, let's limit branches as well. Each of the blocks (tags, bookmarks, branches) currently has a link to the full list.

hgweb: use webutil.branchentries for branches on summary page This allows showing correct status for each branch, which was missing on /summary. Usually that means that closed branches get the same css class (resulting in e.g. different color/shade) as they do on /branches page. The sorting of the branches on summary page also changes and is now the same as on /branches page: closed branches are now at the end of the list.

hgweb: move branchentries code from webcommands to webutil
