scmutil: extract general delta config handling in a function General delta is currently controlled by a single option, we will introduce a new one in the next changeset. We extract the logic in a function while it is simple.

test: test-bundle-type.t needs to work more universally The cut and head utilities on Solaris have weird differences from the GNU versions. The f helper script does a dump more nicely than those tools, anyway.

bash_completion: add -p|--patch|--stat support for shelve

test-convert-git: silence commit output for stablity When running the tests with 1.7.7.6, I get 'files' and 'insertions' instead of the singular forms, and there is also an additional '0 deletions(-)' at the end. Since this doesn't seem important to the test, silence it.

rebase: preserve the 'intermediate-source' attribute of grafts Preserving the 'source' attribute of grafts started with a69a77a80900, which predates the introduction of 'intermediate-source' in 51930a7180bd by a year and a half. It looks like not preserving this was an oversight. On a related note, notice how the source value of 32af76 is no longer visible in the graph above this test. Is it reasonable to import the sha1 translation from evolve.py:relocate() into scmutil or similar, and use that to fixup these attributes as well as the commit message? (I realize that evolve is still experimental, but I don't see a way to do this from the evolve extension.)

verify: add a hook that can let extensions manipulate file lists Without a hook of this nature, narrowhg[0] clones always result in 'hg verify' reporting terrible damage to the entire repository history. With this hook, we can ignore files that aren't supposed to be in the clone, and then get an accurate report of any damage present (or not) in the repo. 0: https://bitbucket.org/Google/narrowhg

resolve: don't abort when file is missing A file being missing is a completely valid situation in which the user may want to re-resolve merge conflicts. Mercurial already maintains backups of local data, so this turns out to be easy to handle.

filemerge: treat EOF at prompt as fail, not abort Previously we'd abort the merge entirely if there was an EOF at the prompt. This is unnecessary -- it's much better to simply fail and treat the file as unresolved instead.

test-merge-tools.t: add 'hg resolve --list' output to tests In upcoming patches we're going to be making some improvements to the ':prompt' merge tool, and one of them is recovering appropriately from exceptions. It is important in such cases to make sure that the merge state is written out properly. I went through the output and verified that it all makes sense.

error: add structured exception for EOF at prompt We'll catch this exception for promptchoice queries to provide better error handling.

test-merge-prompt.t: unset HGMERGE We're going to test behavior with and without HGMERGE, so disable it for the test.

hgweb: compute changeset parents and children for log pages lazily Log pages, i.e. changelog, filelog and search results page computed children and parents for each changeset shown, because spartan hgweb style shows this info. Turns out, computing all this is heavy and also unnecessary for log pages in all other hgweb styles. Luckily, templates allow an easy way to do computations on demand: just pass the heavy part of code as a callable and it will be only called when needed. Here are some benchmarks on the mercurial repository (best of 3): time wget http://127.0.0.1:8021/ before: 0m0.050s after: 0m0.040s time wget http://127.0.0.1:8021/?revcount=960 before: 0m1.164s after: 0m0.389s time wget http://127.0.0.1:8021/log/tip/mercurial/commands.py before: 0m0.047s after: 0m0.042s time wget http://127.0.0.1:8021/log/tip/mercurial/commands.py?revcount=960 before: 0m0.830s after: 0m0.434s

filemerge: move :merge-local/other symlink check to precheck In upcoming patches we're going to add more checks to the function currently named _symlinkcheck. This consolidates all those checks.

test-merge-types.t: add tests for :merge-local/:merge-other with symlinks This had no test coverage.

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.

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
