dirstate._walkexplicit: drop normpath calls The paths the matcher returns are normalized already.

dirstate._walkexplicit: indicate root as '.', not '' '.' is the canonical way to represent the root, and it's apparently the only transformation that normpath makes.

phases: add killswitch for native implementation

phases: move pure phase computation in a function

revset: add hook after tree parsing This will be useful to execute actions after the tree is parsed and before the revset returns a match. Finding symbols in the parse tree will later allow hashes of hidden revisions to work on the command line without the --hidden flag.

hgk: remove unused revlog import

run-tests: obtain replacements inside Test._runcommand Now that command running is part of Test, we no longer need to pass a list of replacements down through various call layers. The impetus for this change is to fetch replacements after command execution, not before. This will allow replacements to be defined as part of test execution.

hgk: remove no longer needed debug-rev-parse command

hgk: remove no longer needed debug-config command

hgk: display obsolete changesets in darkgrey

hgk: pass --hidden switch to hg subprocesses when needed

hgk: remove repetitious (and wrong) command syntax descriptions

run-tests: separate newline normalization from replacements Upcoming patches will change how the replacements system works to make it more flexible. To prepare for this, eliminate the one-off use of replacements to perform newline normalization on Windows.

run-tests: remove arguments from Test._runcommand Now that runcommand is part of the Test class, arguments that were previously coming from Test attributes can now be switched to lookups inline.

run-tests: move run into Test class Future patches will change how replacements work. Since the logic in run() is strongly tied to the operation of individual tests and since there is potential to make the implementation simpler by giving the function access to Test attributes, move it into Test.

run-tests: wait for test threads after first error The test runner has the ability to stop on first error. Tests are executed in new Python threads. The test runner starts new threads when it has capacity to do so. Before this patch, the "stop on first error" logic would return immediately from the "run tests" function, without waiting on test threads to complete. There was thus a race between the test runner thread doing cleanup work and the test thread performing activity. For example, the test thread could be in the middle of executing a test shell script and the test runner could remove the test's temporary directory. Depending on timing, this could result in any number of output from the test runner. This patch eliminates the race condition by having the test runner explicitly wait for test threads to complete before continuing. I discovered this issue as I modified the test harness in a subsequent patch and was reliably able to tickle the race condition.

run-tests: report code coverage from source directory As part of testing code coverage output, I noticed some files were being reported twice: there was an entry for the file in the install location and for the file in the source tree. I'm not sure why this is. But it resulted in under-reporting of coverage data since some lines weren't getting covered in both locations. I also noticed that files in the source directory and outside the "mercurial" and "hgext" packages were getting included in the coverage report. Cosmetically, this seemed odd to me. It's not difficult to filter paths from the report. But I figure this data can be useful (we could start reporting run-tests.py coverage, for example). This patch switches the coverage API to report code coverage from the source directory. It registers a path alias so that data from the install location is merged into data from the source directory. We now get merged results for files that were being reported in multiple locations. Since code coverage reporting now relies on the profiled install now being in sync with the source tree, an additional check to disallow code coverage when --with-hg is specified has been added. This should have been present before, as --local was previously disallowed for the same reasons. Merging the paths raises our aggregate line coverage from ~60 to 81%.

run-tests: collect aggregate code coverage Before this patch, every Python process during a code coverage run was writing coverage data to the same file. I'm not sure if the coverage package even tries to obtain a lock on the file. But what I do know is there was some last write wins leading to loss of code coverage data, at least with -j > 1. This patch changes the code coverage mechanism to be multiple process safe. The mechanism for initializing code coverage via sitecustomize.py has been tweaked so each Python process will produce a separate coverage data file on disk. Unless two processes generate the same random value, there are no race conditions writing to the same file. At the end of the test run, we combine all written files into an aggregate report. On my machine, running the full test suite produces a little over 20,000 coverage files consuming ~350 MB. As you can imagine, it takes several seconds to load and merge these coverage files. But when it is done, you have an accurate picture of the aggregate code coverage for the entire test suite, which is ~60% line coverage.

run-tests: obtain code coverage via Python API Before, we were invoking the "coverage" program provided by the "coverage" module. This patch changes the code to go through the Python API. This makes the next patch a little bit easier to reason about. A side effect of this patch is that writing code coverage reports will be slightly faster, as we won't have to redundantly load coverage data.

commands.debugrevlog: report max chain length This is sometimes useful to know. Report it.

_lazymanifest: drop unnecessary call to sorted() The entries returned from _lazymanifest.iterentries() are already sorted.

test-git-export: add globs the test runner wants on Windows The only difference for the first two was to add the globs, but the third line of output on Windows was '..\dir2\copy'. I'm not sure why 'copy' is output on Windows instead of '*'.

run-tests: explicitly handle unicode when writing xunit file The xunit writer was passing a str to a minidom API. An implicit .decode('ascii') was performed somewhere, causing UnicodeDecodeError if test output contained non-ascii sequences. This patch converts test output to utf-8 before passing it to minidom. We use the "replace" strategy to ensure invalid utf-8 sequences get munged into �.

parsers.c: avoid implicit conversion loses integer warnings These warnings are raised by Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn) and were introduced in 539b3c7eea44

test-annotate: conditionalize error output for Windows It seems better to leave the actual output in place instead of globbing everything but 'abort:', in case it starts aborting for other reasons. It isn't clear the purpose for reversing the file name position, but that originates in windows.posixfile.

test-diffstat: add a glob the test runner wants on Windows The test gets a '~' status without it.

tests: add testing for diff.showfunc The diff.showfunc config knob did not have coverage before.

manifest: make manifest.intersectfiles() internal manifest.intersectfiles() is just a utility used by manifest.matches(), and a future commit removes intersectfiles for treemanifest for optimization purposes. This commit makes the intersectfiles methods on manifestdict and treemanifest internal, and converts its test to a more generic testMatches(), which has the exact same coverage.
