commands: add norepo argument to command decorator Since decorators are evaluated at module load time and since the @command decorator imports commands, the norepo variable (along with its friends) may not be declared yet. These variables are now declared before @command usage to ensure they are present.

cmdutil: better document command()

convert: update the transplant, rebase and graft references in 'extra' This change allows the origin() and destination() revsets to yield the same results in the new and old repos after a conversion. Previously, nothing would be listed for queries in the new repo. Like the SHA1 updates to the commit messages, this is only operational when the 'convert.hg.saverev=True' option is specified. If the old reference cannot be found, it is left as-is. It seems slightly better to leave stale evidence of the graft/transplant/rebase than to eliminate it entirely.

run-tests: hold iolock across diff/prompt when interactive Otherwise diff may get separated from the corresponding prompt by other threads. This required moving the interactive prompting from one helper method to another.

test-run-tests.t: test the --nodiff option

test-run-tests.t: test the --interactive option

run-tests: fixes the '--interactive' option error This patch fixes a regression recently introduced by a refactoring. Previously when failure occurs while testing with '--interactive' was enable, it didn't prompt user by asking whether he wants to accept this failure changes or not. This was happening beacuse of the 'if' condition if ret or not self._options.interactive or \ not os.path.exists(test.errpath): Everytime failure occurs, this condition gets true and returns back even when '--interactive' is enabled. This condition don't led the function to execute further, which consist the '--interactive' functionality. Now, on failure with '--interactive' enabled, it prompts user whether he wants to accepts failure changes or not. If yes then test gets passed and returns true, else test gets failed. On every failure, results gets stored in "self.failures.append((test, reason))" But if failure changes accepted by user then test must get "pop out" from failed test list.

run-tests: checks behaviour of test on failure while testing On failure while testing, if this function "result.addFailure(self, str(e))" returns true then test get 'passed' else count as 'failed'.

revlog: hold a private reference to self._cache This keeps other threads from modifying self._cache out from under us. With this and the previous fix, 'hg serve' survives 100k hits with siege.

revlog: make _chunkcache access atomic With this and related fixes, 'hg serve' survived 100000 hits with siege.

tests: cat error messages are different on Solaris
