changegroup: extract condition for linkrev fastpath The condition for taking the fastpath (or not) is used in two places. By extracting it, we also provide a place to document what it's about.

lazymanifest: drop SP before some labels These seem to be the only occurrences in our code base, so let's make it consistent.

lazymanifest: avoid 'bail' label when used on success path 3d485727e45e (lazymanifest: extract function for iterating to next line, 2015-03-11) introduced a large memory leak because I stopped running the 'bail' block in the successful case. Let's rename 'bail' to 'done', since it has to run not only in the error case.

dockerdeb: rules to build a debian package using docker Currently only supports jessie (current stable), but other version should be trivial.

packaging: extract packagelib for common code from builddeb and buildrpm

builddeb: new script for building a deb package Future work will allow us to use docker to build debs. Right now this doesn't install any config files. I plan to do that as a followup, but getting something basic and working checked in seems like more of a priority than getting everything done in one big step. This also does not create a source deb yet. I haven't looked into that process. Note that this declares incompatibility with the `mercurial-common` package. It's typical for debian packages to be split between architecture-independent bits and native bits, meaning the python bits downstream live in mercurial-common and the c extension bits live in mercurial. We don't do that because we want to (ideally) give users a single deb file to install.

dockerlib: fix initcontainer for boot2docker users This allows me to build rpm packages using boot2docker on my Mac. It's probably a very fragile hack, but it seems to work well enough for now that I felt it was worth sharing.

dockerlib: extract initcontainer() method This helps contain all the logic around creating containers.

dockerlib: start extracting common functions for setting up docker I'm about to start interacting with docker for Debian packaging too, so it's time to centralize this so that any bugfixes I figure out apply to both codepaths.

run-test: ensure the test ports are available before launching test I'm running into a systematic issue because there is always some port taken in the 1500-wide range of ports used by the test (3 for each test file).

templater: strip single backslash before quotation mark in quoted template db7463aa080f fixed the issue of double escapes, but it made the following template fail with syntax error because of <\">. Strictly speaking, <\"> appears to be invalid in non-string part, but we are likely to escape <"> if surrounded by quotes, and we are used to write such templates by trial and error. [templates] sl = "{tags % \"{ifeq(tag,'tip','',label('log.tag', ' {tag}'))}\"}" So, for backward compatibility between 2.8.1 and 3.4, a single backslash before quotation mark is stripped only in quoted template. We don't care for <\"> in string literal in quoted template, which never worked as expected before. template result --------- ------------------------ {\"\"} parse error "{""}" {""} -> <> "{\"\"}" {""} -> <> {"\""} {"\""} -> <"> '{"\""}' {"\""} -> <"> "{"\""}" parse error (don't care)

run-tests: implement Test._testMethodName This methods is needed internally by utilities like __repr__. I do not see any harm in having it declared. Any actual attempt to use it to call a test would crash, but at least random debug print in the test runner will no longer crash. Another approach would have been to redefine the __repr__ function, but I think it a good thing to have some respect for the base class API.

test-subrepo-git: ignore pax_global_header when listing archive 5115d03440f4 is adding a new tar call but forgot to filter out the pax_global_header file that some tar versions write. This is similar to what happened in 5dda6c708138.

test-subrepo-recursion: glob out all the date listed by unzip -l This date output is unstable (01-01-1980 vs 1980-01-01). As the test is not about the modification date, we glob the data out. Caught by buildbot.

bookmarks: remove unused updatecurrentbookmark function (API) This function was not used anywhere in core and there is no indication that it is used elsewhere either.

changelog: drop unnecessary override of "hasnode" revlog.hasnode() calls self.rev(node) that takes filtering into account.

test-run-test: unset run-test specific environment variables Otherwise variable set for the real test run interfere with the test runner tests.

histedit: fix --continue when rules are finished If histedit failed after all the rules were complete (for instance, if there was an exception in the cleanup phase), you couldn't --continue because it was unable to pop a rule. Let's just skip the rule execution phase of --continue if there are no more rules.

histedit: fix serializing of None backupfile If the histedit backupfile was None (like if evolve is enabled) it would get serialized as 'None' into the state file. Later if the histedit was aborted and the top most commit was unreachable (ex: if it was obsolete or stripped), histedit would try to unbundle the backupfile and try to read .hg/None. This fixes it to not serialize None. Since it only happens with evolve, I'm not sure how to add test coverage here.

merge with stable

treemanifest: set requires at repo creation time, ignore config after The very next changeset will start writing one revlog per directory when tree manifests are enabled. That is backwards incompatible, so it requires .hg/requires to be updated. Just like with generaldelta, we want to update .hg/requires only when the repo is created. Updating ..hg/requires is bad for repos on shared disk. Instead, those who do want to upgrade a repo to using treemanifest (or manifestv2, etc) can run hg clone --config experimental.treemanifest repo clone which will create a new repo with the requirement set. Unlike the case of e.g. generaldelta, it will not rewrite the changesets, since tree manifests hash differently.

remove: use ctx.hasdir(f) instead of 'f in ctx.dirs()' This speeds up 'hg remove python/README' on the Firefox repo from 2.479s to 0.664s with lazily loaded treemanifests (which is not yet in core) and has no measurable effect on flat manifests.

largefiles: drop os.path.join() in subrepo archive override This is related to 41cd8171e58f, but not required for that to function correctly because 'prefix' always ends with '/', so os.path.join(prefix, _path) simply concatenates the strings. Take the opportunity to drop the os.path usage, and avoid confusion by using the same pattern as the overridden subrepo method.

archive: drop the leading '.' path component from the prefix (issue4634) Unix utilities like tar will happily prefix the files it packs with './', but annoyingly, Windows Explorer will not show these packed files when it opens the archive. Since there doesn't seem to be a point in including './' in the path names, just drop it. The default 'hg archive' prefix is the basename of the archive, so specifying '.' allows for that default to be disabled completely.
