cat: disable optimization of single file case for workingctx It crashes because workingctx has no manifest.

committablectx: override manifestnode() to return None wctx.manifestnode() crashed before because it has no _changeset. Instead of crashing, just return None like wctx.node().

cat: use ctx.manifestnode() in place of ctx._changeset[0]

changegroup: flush the ui stdio buffers after adding a changegroup This eliminates the following test failure on Windows, as well as a similar one in evolve's test-wireproto.t.

What is happening is that no data is available in 'sshpeer.pipee' while the command is executing. As the command completes, local output is printed, and then sshpeer.cleanup() is called. When it calls 'self.pipeo.close()', the child process is shutdown, flushing stderr. As an experiment, I printed a line to stdout and another to stderr instead this flush(). The stdout data was immediately available to the hg client, and none of the stderr data was until the child exited. At that point, pipee has all of the buffered data, and it is read out and printed before the pipe is closed in sshpeer.cleanup(). This is probably a known issue, since ui.write_err() mentions that stderr may be buffered, and also flushes stderr. It would be nice if there was a more general fix (there is one more test that fails), but I'm not sure what it is. I've seen (ancient) references [1] to setvbuf() "crashing spectacularly" on some systems if any I/O has been done already, so it seems worth avoiding. https://sourceware.org/ml/gdb-patches/2013-08/msg00422.html [1] https://groups.google.com/forum/#!msg/comp.lang.python/JT8LiYzYDEY/Qg9d1HwyjScJ

json: implement {fileannotate} template

json: implement {comparison} template Similar to {filediff}, we abbreviate some property names to cut down on string bloat.

json: implement {filediff} template Single letter properties are used to keep payload size down, as diff representation can be quite large and longer property names can create a lot of extra work for parsers. Rename is not yet captured. This can be done in a follow-up.

hgweb: expose raw line numbers to templates Surpringly, the templates didn't receive an unmodified version of the line numbers. Expose it to make implementing the JSON templates easier. In theory, we could post-process an existing template variable. But extra string manipulation seems quite wasteful, especially on items that could occur hundreds or even thousands of times in output.

revert: stop marking files clean after interactive revert (issue4592) The goal of 'hg revert --interactive' is usually to keep some change in the revert file, so the files -must-not- be marked as clean. We want the status logic to do its usual job here. For unclear reasons (probably timing related), I was unable to build an automated test that reproduced issue4592 but manual testing shows this is fixed.

lazymanifest: prevent leak when updating an entry more than once __setitem__ on the lazymanifest C type wasn't checking to see if a line had previously been malloced before replacing it, leading to leaks if files got updated multiple times in the course of a task. I was able to reproduce the leak with this change to test-manifest.py: diff --git a/tests/test-manifest.py b/tests/test-manifest.py --- a/tests/test-manifest.py +++ b/tests/test-manifest.py @@ -456,6 +456,16 @@ class basemanifesttests(object): ['a/b/c/bar.txt', 'a/b/c/foo.txt', 'a/b/d/ten.txt'], m2.keys()) + def testManifestSetItem(self): + m = self.parsemanifest('') + for x in range(3): + m['file%d' % x] = BIN_HASH_1 + for x in range(3): + m['file%d' % x] = BIN_HASH_2 + import time + time.sleep(4) + + along with the commands: $ make local $ PYTHONPATH=.

As far as I can tell, it had to be an interactive shell so that I could get the pid of the test run using the jobs builtin. Prior to this change, I was leaking several strings, and after this change leaks reports no leaks. I thought there was a bug filed for this in bugzilla, but I can't find it either in bugzilla or by searching my email.

strip: properly clear resolve state with --keep (issue4593) Normal updates automatically clean up the resolve state, but strip --keep does a "manual" update that bypasses the normal machinery. This adds a mergestate reset.

revsets: more informative syntax error message I came across a case where an internal command was using a revset that I didn't immediately pass in and it was difficult to debug what was going wrong with the revset. This prints out the revset and informs the user that the error is with a rebset so it should be more obvious what and where the error is.

revsets: show current revset abort behavior

tests: move blackbox testing of tags to test-tags.t We're going to refactor tags cache shortly. It is easier to test the blackbox logging if these tests are in test-tags.t.

tests: move mock blackbox extension into own file Having all blackbox log testing in test-blackbox.t isn't scalable. Move the mock blackbox extension into its own file so we can start to move blackbox logging into other tests.

shelve: acquire lock in the right order Text book says that 'wlock' should be acquired before 'lock'. Caught through developer warning.

check-commit: be more picky about detection of wrong bug tag The check-commit script search for "bug" withing bracket and ask people to use (issueXXXX) instead. The test was too wide and matching any "(+b+u+g"sequence.

discovery: don't compute allfuturecommon when it won't be used In repos with many changesets, the computation of allfuturecommon can take a significant amount of time. Since it's only used if there's an obsstore, don't compute it otherwise.

treemanifest: separate flags for trees in memory and trees on disk When we start writing tree manifests with one manifest revlog per directory, it will still be nice to be able to run tests using tree manifests in memory but writing to a flat manifest to a single revlog. Let's break the current '_usetreemanifest' flag on the revlog into '_treeinmem' and '_treeondisk'. Both are populated from the same config, but after this change, one can temporarily hard-code _treeinmem=True to see that tests still pass.

manifestdict: drop empty-string argument when creating empty manifest manifestdict() creates an empty manifestdict, so let's consistently use that instead of explicitly parsing an empty string (which does result in an empty manifest).

lazymanifest: fix memory leak in lmiter_iterentriesnext() after 3d485727e45e

revert: do not requires '--all' if '--interative' is present The '--all' option have been introduced in 890e285c52a1 (August 2006), most probably to prevent user shooting themselves in the foot. As the record process will let you, view and select the set of files and change you want to revert, I feel like the '--all' flag is superfluous in the '--interactive' case.

bundle2: drop the experimental hooks The series at e9ede9b4c2f8::8e13cc0825f1 introduced generic transaction level hooking. This makes the experimental bundle2 specific hooks redundant, we drop them.

bundle2: advertise bundle2 by default That way, any new server will be ready to accept bundle2 payload. The decision for the client to use it is still off by default so this is not turning bundle2 everywhere. We introduce a new kill switch for this in case stuff goes wrong.

subrepo: convert the os.path references in git to vfs There are a handful of os.path references in the free functions at the top of the module that will be trickier to remove.

subrepo: use vfs.removedirs instead of os.removedirs This patch also removes useless composing absolute path by "repo.wjoin()".

vfs: add removedirs

util: add removedirs as platform depending function According to fa901423ac23 introducing "windows._removedirs()": If a hg repository including working directory is a reparse point (directory symlinked or a junction point), then using os.removedirs will remove the reparse point erroneously. "windows._removedirs()" should be used instead of "os.removedirs()" on Windows. This patch adds "removedirs" as platform depending function to replace "os.removedirs()" invocations for portability and safety

subrepo: use vfs.unlink instead of os.remove This patch also removes useless composing absolute path by "os.path.join()".
