vfs: add "isfile()"

transaction: unlink target file via vfs Before this patch, unlink target file is once opened before unlinking, because "opener" before vfs migration doesn't have "unlink()" function. This patch uses "vfs.unlink()" instead of "open()" and "fp.name".

relink: abort earlier when on different devices (issue3916) Add a first check of the devices before collecting candidate files. This is much quicker when big repos are on different devices. Keep the existing check in prune. It checks for same device of the files. This could probably be different in a special repo store (with symlinks).

localrepo: prevent to copy repo local config, copy baseui instead Copying a repos local configuration to another repo is a bad idea because the 2nd repo gets the configuration of the first. Prevent this by really calling repo.baseui.copy when repo.ui.copy is called. This requires some changes in commandserver which needs to clone repo.ui for rejecting temporary changes. This patch has its roots back in the topic "repo isolation" around f0564402d059 and was suggested by mpm.

doc: show details of command options in pages generated by docutils Before this patch, HTML/man pages generated by docutils don't show details of each command options, whether it should take argument or not for example, even though "hg help" does. This patch shows details of command options as same as "hg help" shows. This patch uses "--option <VALUE[+]>" style instead of "--option <VALUE> [+]" used in output of "hg help", because docutils requires that option argument strings starts with "<" and ends with ">".

Makefile: intermediate steps work with temporary copy of hg.pot In case of abortion or a failing step, the target file remains untouched instead of being in an intermediate state.

help: drop help for branches template keyword The {branches} keyword dates to pre-1.0 Mercurial's tag-like branch scheme which allowed changesets to be on multiple branches. This is the last visible vestige of that scheme, users should instead be using {branch}, possibly with if().

test-command-template.t: fix failure due to trailing whitespace

templater: makes branches work correctly with stringify (issue4108)

manifest: increase lrucache from 3 to 4 During a commit amend there are 4 manifests being handled: - original commit - temporary commit - amended commit - merge base This causes a manifest cache miss which hurts perf on large repos. On a large repo, this fix causes amend to go from 6 seconds to 5.5 seconds.

strip: add faster revlog strip computation The previous revlog strip computation would walk every rev in the revlog, from the bottom to the top. Since we're usually stripping only the top few revs of the revlog, this was needlessly expensive on large repos. The new algorithm walks the exact number of revs that will be stripped, thus making the operation not dependent on the number of revs in the repo. This makes amend on a large repo go from 8.7 seconds to 6 seconds.

revlog: return lazy set from findcommonmissing When computing the commonmissing, it greedily computes the entire set immediately. On a large repo where the majority of history is irrelevant, this causes a significant slow down. Replacing it with a lazy set makes amend go from 11 seconds to 8.7 seconds.

histedit: hold wlock and lock while in progress Currently, histedit acquires and releases lock and wlock several times during its run. This isn't great because it allows other hg processes to come in and change state. With this fix, lock and wlock are acquired and released exactly once. The change to test-histedit-drop.t is a minor implementation one -- the cache is still correctly invalidated, but it just happens a little later and only gets printed out because of the unrelated --debug flag.

templater: only recursively evaluate string literals as templates (issue4103)

templater: fix escaping in nested string literals (issue4102) Before the templater got extended for nested expressions, it made sense to decode string escapes across the whole string. Now we do it on a piece by piece basis.

shelve: unshelve using an unfiltered repository when evolve is enabled and a hidden obsolete changeset exists in the repository, the strip during unshelve will fail due to filtered revs. we use an unfiltered repository like to repair.strip to strip the proper nodes.

largefiles: update in two steps, handle interrupted updates better An update would try to fetch any missing largefiles after having updated normal files and standins. That could fail or be interrupted and would leave the working directory in a state where the largefiles not only were missing but also were scheduled for remove ... and where the old largefile was left in place. Instead we now remove old largefiles before starting to download and update missing largefiles.

largefiles: inline _updatelfile, prepare for further refactorings

largefiles: cache largefiles for update, also without printmessage

largefiles: cleanup of printmessage handling - the printed flag was redundant

convert: fix svn crash when svn.ra.get_log calls back with orig_paths=None get_log started calling back with orig_paths=None on Fedora 20 with subversion-1.8.3. That broke test-convert-svn-source.t . There used to be some handling of that situation until e8f4e40f285a apparently broke it. This patch restores what seems to be the most obvious handling of the situation.

share: fix unshare calling wrong repo.__init__() method When running the unshare command, if there's other code that tries to use the repo after the command is finished, it'll end up with a ui object for repo.unfiltered(). This change fixes an erroneous call to repo.__init__() that could be on the repoview proxy class--now it's always done on the unfiltered repo.

statichttprepo.httprangeheader: implement readlines bookmarks.readcurrent() requires readlines() on file objects returned from repo.vfs. It isn't used right now but will be in upcoming patches.

statichttprepo: pass in True to splitlines, not 1 splitlines actually takes a boolean.

scmutil.filecache: support watching over multiple files

scmutil: introduce a filecacheentry that can watch multiple paths

scmutil: rename filecacheentry to filecachesubentry Upcoming patches will allow the file cache to watch over multiple files, and call the decorated function again if any of the files change. The particular use case for this is the bookmark store, which needs to be invalidated if either .hg/bookmarks or .hg/bookmarks.current changes. (This doesn't currently happen, which is a bug. This bug will also be fixed in upcoming patches.)

scmutil.filecacheentry: make stat argument to constructor mandatory There's no real upside to making stat optional -- this constructor has just two callers.

test-filecache.py: add markers to the output for each event Previously it was possible that a different, incorrect set of events might print out 'creating' the same number of times.

test-filecache.py: make setbeforeget test clearer '0' and 'None' as outputs tripped me up. Make the distinction between values set externally and values computed by calling the decorated function clearer.

test-module-imports.t: new test to use the import cycle detector

import-checker: try a little harder to show fewer cycles This makes sure that all cycles begin with the lexicographically first module, so that we're less likely to show overlapping cycles in the final analysis.

import-checker: ignore nested imports

contrib: add an import checker This checks for cycles in the module graph and verifies that imports of stdlib modules are not on the same line as relative imports of mercurial modules.

makememctx: move from patch to context to break import cycle

cleanup: move stdlib imports to their own import statement There are a few warnings still produced by my import checker, but those are false positives produced by modules that share a name with stdlib modules.

pathutil: tease out a new library to break an import cycle from canonpath use

subsettable: move from repoview to branchmap, the only place it's used This is a step towards breaking an import cycle between revset and repoview. Import cycles happened to work in Python 2 with implicit relative imports, but breaks on Python 3 when we start using explicit relative imports via 2to3 rewrite rules.

obsolete: add __eq__ and __hash__ to marker to make set() deduplication work

obsolete: do not accept duplicated marker during exchange Before this patch, duplicated obsolescence markers could slip into an obstore if the bookmark was unknown locally and duplicated in the incoming obsolescence stream. Existing duplicate markers will not be automatically removed but they'll stop propagating. Having a few duplicated markers is harmless and people have been warned evolution is <blink>experimental</blink> anyway.

obsolete: stop doing membership test on list According to the Surgeon General, computer should not use list for membership testing because of the risk of being slow.

bookmarks: rewrite pushing bookmarks in "localrepository.push()" by "compare()" This patch adds "updateremote()", which uses "compare()" to compare bookmarks between the local and the remote repositories, to replace pushing local bookmarks in "localrepository.push()".

bookmarks: rewrite pushing local bookmarks in "commands.push()" by "compare()" This patch adds "pushtoremote()", which uses "compare()" to compare bookmarks between the local and the remote repositories, to replace pushing local bookmarks in "commands.push()".

bookmarks: rewrite "updatefromremote()" by "compare()" To update entries in bmstore "localmarks", this patch uses "bin(changesetid)" instead of "repo[changesetid].node()" used in original "updatefromremote()" implementation, because the former is cheaper than the latter.

bookmarks: add function to centralize the logic to compare bookmarks This patch adds "compare()" function to centralize the logic to compare bookmarks between two repositories.

hgweb: use semantically suitable filelog.revs in filelog The functions are equivalent in behaviour, so no behavior change.

hgweb: always compute all entries and latestentry in filelog This is the same thing which was done for changelog earlier, and it doesn't affect performance at all. This change will make it possible to get the first entry of the next page easily without computing the list twice.

hgweb: remove unused argument of entries function in filelog This doesn't change the behavior as the argument wasn't used anyway.

transplant: use peer of source repository as "remote" for "repo.pull()" Before this patch, transplant with "--merge" option fails with traceback unexpectedly, if it causes pull from the source repository on the local host. "discovery.findcommonincoming()" invokes "capable()" method on the object given from "localrepository.pull()", but it is "localrepository" object in this case and doesn't have such method. This patch uses peer object of source repository as "remote" argument for "localrepository.pull()" invocation like other invocations of it in transplant.py.

run-tests: remove files that we potentially create outside of $TMPDIR

run-tests: remove code that creates a dummy 'diffstat' This was introduced in fb1d7a42663c for an old test that is no longer the same.

template: change extras to use showlist rather than manual templ call. This enables start_extras and end_extras in template maps.

help: adding example 'extras' printing to 'hg help templates'

help: document about {extras} template keyword This adds text about the "extras" template keyword, similar to that proposed by Yuya Nishihara previously.

check-code: document last ignore regexp For easier remembering to delete when it is not needed anymore.

check-code: drop unneeded ignore patterns The exceptions seem to have disappeared.

contrib: add editmerge script for editor conflict prompts Adds a script that opens the editor to the conflict as part of the merge process. This way you can fix the merge during the rebase instead of having to pause the rebase, resolve --mark, rebase --continue. Only works on unix.

strip: fix last unprotected mq reference (issue4097)

tests: skip tests that require not having root (issue4089) This adds a new root hghave to test against. Almost all of these are a subset of unix-permissions, but that is also used for checking exec bit handling.

make: restrict recursion in make clean

scmutil: skip checks in "casecollisionauditor" if filename is already checked Before this patch, almost all of check code in "casecollisionauditor.__call__()" is executed, even if specified filename is already checked, because "f in self._newfiles" is examined lastly. In addition to it, adding "fl" to "self._loweredfiles" and "f" to "self._newfiles" are also redundant in such case. This patch checks "f in self._newfiles" first, and returns immediately to avoid execution of check code for efficiency.

check-code: prepend warning prefix only once, but for each warning The code adding the prefix is now run once per pattern. It was run once per file (after the change 3e1e4a8aec1e). Demonstrate that it is working now by extending the test. Raise two different warnings, one of them twice.

hgweb, i18n: do not translate search mode description The search mode description can't be translated by itself, since it's displayed as part of a template phrase (the "Assuming ..." / "Use ... instead" bits). Just drop the translation markers for now, since the templates themselves currently do not support translations.

tests: end output lines including path with "(glob)" to pass on Windows

tests: quote environment variable to extract wildcard on MinGW environment On MinGW environment, the command line below in test script can't extract wildcard "*" and remove target files correctly. $ rm $ENVVAR/foo/bar.* To extract wildcard, environment variable should be quoted by double quotation like below: $ rm "$ENVVAR"/foo/bar.* This patch also omits "-f" of "rm" to know whether files are removed or not by exit code of it.

tests: choose the path separator in PYTHONPATH suitable for platform Before this patch, test code introduced by e3a5922e18c3 into test-extension.t always uses ":" as the path separator in PYTHONPATH. But ";" should be used on Windows. This patch chooses the path separator in PYTHONPATH suitable for platform.

util: warn when adding paths ending with \ Paths ending with \ will fail the verification introduced in 684a977c2ae0 when checking out on Windows ... and if it didn't fail it would probably not do what the user expected.

check-code: more replacement characters for finding '.. note::' (even) more exact by using more characters: replace '.' with 'p' and ':' with 'q'

check-code: check comment for '.. note::' without two newlines Because string entries are replaced before matching, we must search for the transformed pattern. But it seems to be quite unique and does not return false matches. If it will, they can be listed as 3rd arg in pypats.

documentation: add an extra newline after note directive Like this no docutils version interprets any line in the following text as argument of note.

tests: modify minirst test input to new format Modifying the test input data shows the effects of the last patches. In text output nothing has changed. In html output the title has moved on its own line.

minirst: do not add a 2nd empty paragraph This does not add a separating block after a separated note directive. .. note:: text is formatted to Note: text

minirst: find admonitions before pruning comments and adding margins Lines with only a directive are not deleted anymore because they are detected before comments are deleted by prunecomments(). addmargins() will be adapted later.

minirst: do not fail on an empty admonition block

minirst: do not interpret a directive as a literal block When a directive was on its own line, it was interpreted as a literal block. Example of problematic input: .. note:: a note text

Makefile: do update on a temporary copy of a po file This avoids having a half completed file (with a new timestamp) when msgmerge has failed.
