extensions: extract partial application into a bind() function We use partial function application for wrapping existing Mercurial functions, and it's implemented separately each time. This patch extracts the partial application into a new bind() function that can be used on its own by extensions when appropriate. In particular, the evolve extension needs to wrap functions in the various bundle2 processing dictionaries, which the pre-existing methods don't support.

obsolete: experimental flag to get debug about obsmarkers exchange The obsolescence markers exchange is still experimental. We (developer) need more information about what is going on. I'm adding an experimental flag to add display the amount of data exchanged during bundle2 exchanges.

bundle2: add an 'idx' argument to the 'getbundle2partsgenerator' This argument let extensions control in what order bundle2 part are generated server side during a pull. This is useful to ensure the transaction is in a proper state before some actions or hooks happens.

bundle2: add an 'idx' argument to the 'b2partsgenerator' This argument let extensions control in what order bundle2 part are generated client side during a push. This is useful to ensure the transaction is in a proper state before some actions or hooks happens.

rpms: create missing builds dir if it doesn't exist

rpms: for packages with their own python, put it in /opt/python-hg This is more compliant with the FHS and Fedora packaging guidelines.

branchcache: stay silent if failing to read cache files The warning has in some cases incorrectly attributed unrelated problems to rbc. Instead, just do like the branch head cache does and stay quiet when reading fails. The cache will be missing the first time a repo is used. It is a normal situation and there is no reason to make a note of that.

merge: better debug messages before/after invoking external merge tool

subrepo: use vfs.walk instead of os.walk "dirpath" in the tuple yielded by "vfs.walk()" is relative one from the root of specified vfs, and absolute path in the warning message is composed by "vfs.join()". On the other hand, target file "f" exists in "dirpath", and "reljoin()" is needed to unlink "f" by "vfs.unlink()".

vfs: add walk To eliminate "path prefix" (= "the root of vfs") part from "dirpath" yielded by "os.walk()" correctly, "path prefix" should have "os.sep" at the end of own string, but it isn't easy to ensure it, because: - examination by "path.endswith(os.sep)" isn't portable Some problematic encodings use 0x5c (= "os.sep" on Windows) as the tail byte of some multi-byte characters. - "os.path.join(path, '')" isn't portable With Python 2.7.9, this invocation doesn't add "os.sep" at the end of UNC path (see issue4557 for detail). Python 2.7.9 changed also behavior of "os.path.normpath()" (see *) and "os.path.splitdrive()" for UNC path. vfs root normpath splitdrive os.sep required =============== ============== =================== ============ z:\ z:\ z: + \ no z:\foo z:\foo z: + \foo yes z:\foo\ z:\foo z: + \foo yes [before Python 2.7.9] \\foo\bar \\foo\bar '' + \\foo\bar yes \\foo\bar\ \\foo\bar (*) '' + \\foo\bar yes \\foo\bar\baz \\foo\bar\baz '' + \\foo\bar\baz yes \\foo\bar\baz\ \\foo\bar\baz '' + \\foo\bar\baz yes [Python 2.7.9] \\foo\bar \\foo\bar \\foo\bar + '' yes \\foo\bar\ \\foo\bar\ (*) \\foo\bar + \ no \\foo\bar\baz \\foo\bar\baz \\foo\bar + \baz yes \\foo\bar\baz\ \\foo\bar\baz \\foo\bar + \baz yes If it is ensured that "normpath()"-ed vfs root is passed to "splitdrive()", adding "os.sep" is required only when "path" part of "splitdrive()" result isn't "os.sep" itself. This is just what "pathutil.nameasprefix()" examines. This patch applies "os.path.normpath()" on "self.join(None)" explicitly, because it isn't ensured that vfs root is already normalized: vfs itself is constructed with "realpath=False" (= avoid normalizing in "vfs.__init__()") in many code paths. This normalization should be much cheaper than subsequent file I/O for directory traversal.

subrepo: pass wvfs to _sanitize instead of absolute path to a subrepository As a preparation for vfs migration of "_sanitize()", this patch passes "wvfs" to "_sanitize()" and use "wvfs.base" instead of absolute path to a subrepository.

repoview: move function for computing filtered hash An upcoming patch will establish per-filter tags caches. We'll want to use the same cache validation logic as the branch cache. Prepare for that by moving the logic for computing a filtered view hash to somewhere central.

revset: don't import discovery at module level discovery.py imports a lot of the world. Pierre-Yves told me to move it to a function-level import to avoid an import cycle in a future patch.

transaction: add missing newline to message Add a missing newline to the "journal was created by a different version of Mercurial" message.

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.
