posix: fix test-permissions regression

dockerlib: allow non-unique uid and gid of $DBUILDUSER (issue4657) There are make targets for building mercurial packages for various distributions using docker. One of the preparation steps before building is to create inside the docker image a user with the same uid/gid as the current user on the host system, so that the resulting files have appropriate ownership/permissions. It's possible to run `make docker-<distro>` as a user with uid or gid that is already present in a vanilla docker container of that distibution. For example, issue4657 is about failing to build fedora packages as a user with uid=999 and gid=999 because these ids are already used in fedora, and groupadd fails. useradd would fail too, if the flow ever got to it (and there was a user with such uid already). A straightforward (maybe too much) way to fix this is to allow non-unique uid and gid for the new user and group that get created inside the image. I'm not sure of the implications of this, but marmoute encouraged me to try and send this patch for stable.

dirstate: fix filefoldmap incosistency on file delete The _filefoldmap is not updated in when files are deleted from dirstate. In the case where the file with the same but differently cased name is added afterwards it renders _filefoldmap incorrect. Those steps must occur to for a problem to reproduce: - call status (with listunknown=True), - update working rectory to a commit which does a casefolding change (A -> a) - call status again (it will show the file "a" as deleted) Unfortunately I'm unable to write a test for it because I don't know any core-mercurial command able to reproduce those steps. The bug was originally spotted when hgwatchman was enabled. It caused the changeset contents change during hg rebase (one file unrelarted to changeset was deleted in it after rebase). The hgwatchman is able to hit it because when hgignore changes the hgwatchmans overridestatus is calling original status with listunknown=True.

wix: style-coal.css has been renamed

clonebundles: fix typo s/comand/command/

posix: retry on symlink race in checklink Multiple threads might attempt to check links with the same temporary name. This would cause one side to get an EEXIST error and wrongly fail the support check. Here, we simply retry if our temporary name exists.

changegroup: back code change of e7c618cee8df out The previous changeset is a simpler way of fixing issue4934 without changing the spirit of the code. We can remove the dual call to 'delayupdate' but we keep the tests to show that the issue is still fixed.

changegroup: call 'prechangegroup' hook before setting up write delay The 'prechangegroup' interfere with 'delayupdate' logic because it trigger the one time call of 'changelog._writepending' (see issure4934). There is no reason not to call that hook before setting up 'delayupdate' so we move the call a bit earlier to avoid interference.

changegroup: fix the scope of a try finally The try finally is here to ensure we release the just-created transaction. Therefore we should not do half a dozen operations before actually entry the try scope.

encoding: re-escape U+DCxx characters in toutf8b input (issue4927) This is the final missing piece in fully round-tripping random byte strings through UTF-8b. While this issue means that UTF-8 <-> UTF-8b isn't fully bijective, we don't expect to ever see U+DCxx codepoints in "real" UTF-8 data, so it should remain bijective in practice.

encoding: use getutf8char in toutf8b This correctly avoids the ambiguity of U+FFFD already present in the input and similar confusion by working a character at a time.

encoding: handle non-BMP characters in fromutf8b

posix: use getutf8char to handle OS X filename percent-escaping This replaces an open-coded utf-8 parser that was ignoring subtle issues like overlong encodings.

encoding: add getutf8char helper This allows us to find character boundaries in byte strings when trying to do custom encodings.

unbundle: gratuitous fix white spacing "issue" We were missing one space on this block.

demandimport: fix level passed to loader of sub-modules As the fromlist gives the names of sub-modules, they should be searched in the parent directory of the package's __init__.py, which is level=1. I got the following error by rewriting hgweb to use absolute_import, where the "mercurial" package is referenced as ".." (level=2): ValueError: Attempted relative import beyond toplevel package I know little about the import mechanism, but this change seems correct. Before this patch, the following code did import the os module with no error: from mercurial import demandimport demandimport.enable() from mercurial import os print os.name

parsers: fix width of datalen variable in fm1readmarkers Because parsers.c does not define PY_SSIZE_T_CLEAN, "s#" format requires (const char*, int), not (const char*, Py_ssize_t). https://docs.python.org/2/c-api/arg.html This error had no problem before 042344313939, where datalen wasn't used. But now fm1readmarkers() fails with "overflow in obsstore" on Python 2.6.9 (amd64) because upper bits of datalen seem to be filled with 1, making it a negative integer. This problem seems not visible on our Python 2.7 environment because upper bits happen to be filled with 0.

manifest: skip fastdelta if the change is large In large repos, the existing manifest fastdelta computation (which performs a bisect on the raw manifest for every file that is changing), is excessively slow. This patch makes fastdelta fallback to the normal string delta algorithm if the number of changes is large. On a large repo with a commit of 8000 files, this reduces the commit time by 7 seconds (fastdelta goes from 8 seconds to 1). I tested this change by modifying the function to compare the old and the new values and running the test suite. The only difference is that the pure text-diff algorithm sometimes produces smaller (but functionaly identical) deltatexts than the bisect algorithm.

merge.mergestate: update docstrings for preresolve and resolve Add a docstring for preresolve, and update the one for resolve.

rebase: pass date parameter to concludenode

rebase: add date parameter to concludenode function This parameter will allow us to set the date of rebased commits

hgweb: remove unused colorPart() from mercurial.js Looks like the function wasn't ever used since its introduction in 0dba955c2636, since setColor() below always used "rgb(255, 255, 255)" notation which doesn't need hex digits.

test: enforce non-general delta in 'test-generaldelta.t' If general delta becomes the default, we need to be explicit about what we want to be tested.

test: enforce bundle1 in 'test-push-cgi.t' This test is checking bundle1 application, therefore we have to enforce the generated bundle to be a bundle1.

test: enforce v1 in 'test-debugbundle.t' This test is about bundle1 and should remain so when we move to generaldelta by default.

test: enforce bundle1 in "test-commit-interactive.t" This test generate a bundle to get a binary file to commit. We should ensure this binary file remains the same when we move to general delta as default.

discovery: factor out calculation of heads to not warn about In addition to taking a step towards getting an unreasonably large function factored into smaller, more manageable functions, this will allow extensions such as remotenames have more control over what pushes are allowed or not.

hooks: back 9f272bf3b342 out Changeset 9f272bf3b342 alters the 'HG_PENDING' mechanism to be "always" there. This change is made under the assumption than we previously did it only when "writepending() actually wrote something". This assumption was wrong, 'writepending()' informs of pending changes the first time something is written and for all following calls. We back this change out to restore the former behavior, which was already correct.

hooks: fix hooks not firing if prechangegroup was set (issue4934) We need to call delayupdate again after writing to the changelog. Otherwise the prechangegroup hook consumes the delayupdate subscription and future hooks don't see the pending changes (see issue 4934 for more details). Adds a test that triggers the prechangegroup hook before the pretxnchangegroup hook and verifies that the output of pretxnchangegroup doesn't change.

hooks: always include HG_PENDING Previously we would only include HG_PENDING in the hook args if the transaction's writepending() actually wrote something. This is a bad criteria, since it's possible that a previous call to writepending() wrote stuff and the hooks want to still see that. The solution is to always have hooks execute within the scope of the pending changes by always putting HG_PENDING in the environment.

wireproto: move clonebundles command from extension (issue4931) The SSH peer class accesses wireproto.commands[cmd] as part of encoding command arguments. Previously, the wire protocol command was defined in the clonebundles extension. If the client didn't have this extension enabled (which it likely doesn't since it is meant as a server-side extension), then clients attempting to clone via ssh:// would get a crash due to a KeyError accessing wireproto.commands['clonebundles'] when cloning from a server that is advertising clone bundles. Moving the definition of the wire protocol command to wireproto.py makes this problem go away. A side effect of this code move is servers will always respond to "clonebundles" wire protocol command requests. This should be fine: the server will return an empty response unless a clone bundles manifest file is present and clients shouldn't call the command unless the server is advertising the capability, which only happens if the clonebundles extension is enabled and the manifest file exists.

templatefilters: try round-trip utf-8 conversion by json filter (issue4933) As JSON string is known to be a unicode, we should try round-trip conversion for localstr type. This patch tests localstr type explicitly because encoding.fromlocal() may raise Abort for undecodable str, which is probably not what we want. Maybe we can refactor json filter to use encoding module more later. Still "{desc|json}" can't round-trip because showdescription() modifies a localstr object.

exchange: do not attempt clone bundle if local repo is non-empty (issue4932)

test-clonebundles.t: add test for incremental pull This demonstrates issue4932.

i18n: make sure to include translation of (DEPRECATED) This patch replaces old "DEPRECATED" msgid by "(DEPRECATED)" if that .po file does not have "(DEPRECATED)" but have "... (DEPRECATED)". It is necessary to hide deprecated options correctly.

i18n: do not abuse msgstr of "DEPRECATED" to check for bad translation Because 44cc9f63a2f1 requires the msgstr of "(DEPRECATED)", old *.po files must be blamed. Using "DEPRECATED" would just hide the error. For example, "LANG=da_DK.UTF-8 hg help serve" fails to hide deprecated options right now, but check-translation.py couldn't detect it because da.po has outdated translation of "DEPRECATED".

filemerge.prompt: separate out choice selection and action This will make future patches cleaner.

test-merge-prompt.t: add tests for linear updates + change/delete conflicts Turns out this bit of code was woefully untested.

test-pathencode.py: drop support for Python 2.4

hgweb.server: drop support for Python 2.4

util: drop Python 2.4 compat by directly importing md5 and sha1 There's been a fair amount of cruft here over the years, which we can all just get rid of now.

hgweb: replace some str.split() calls by str.partition() or str.rpartition() Since Python 2.5 str has new methods: partition and rpartition. They are more specialized than the usual split and rsplit, and they sometimes convey the intent of code better and also are a bit faster (faster than split/rsplit with maxsplit specified). Let's use them in appropriate places for a small speedup. Example performance (partition): $ python -m timeit 'assert "apple|orange|banana".split("|")[0] == "apple"' 1000000 loops, best of 3: 0.376 usec per loop $ python -m timeit 'assert "apple|orange|banana".split("|", 1)[0] == "apple"' 1000000 loops, best of 3: 0.327 usec per loop $ python -m timeit 'assert "apple|orange|banana".partition("|")[0] == "apple"' 1000000 loops, best of 3: 0.214 usec per loop Example performance (rpartition): $ python -m timeit 'assert "apple|orange|banana".rsplit("|")[-1] == "banana"' 1000000 loops, best of 3: 0.372 usec per loop $ python -m timeit 'assert "apple|orange|banana".rsplit("|", 1)[-1] == "banana"' 1000000 loops, best of 3: 0.332 usec per loop $ python -m timeit 'assert "apple|orange|banana".rpartition("|")[-1] == "banana"' 1000000 loops, best of 3: 0.219 usec per loop
