py24: remove check-code py24 notation We require python2.6+

py3: convert hghave output to text Before this, Python3 generated: b'skipped: unknown feature: not-py3k\n'

py3: convert prereq bytes to string in run-tests Without this, run-tests would generate: WARNING: Did not find prerequisite tool: b'python3.5'

record: deprecate the extension The feature has been moved into core behind the -i flag. We can safely deprecated the extension and point people at the --interactive flag in core.

templater: use templatefunc to mark a function as template function Using decorator can localize changes for adding (or removing) a template function in source code. This patch also removes leading ":FUNC(ARG...):" part in help document of each function, because using templatefunc makes it useless. This patch uses not 'func' but 'templatefunc' as a decorator name, because the former is too generic one, even though the latter is a little redundant in 'templater.py'.

registrar: add templatefunc to mark a function as template function (API) This patch also adds loadfunction() to templater, because this combination helps to figure out how they cooperate with each other. Listing up loadfunction() in dispatch.extraloaders causes implicit loading template function at loading (3rd party) extension. This patch explicitly tests whether templatefunc decorator works as expected, because there is no bundled extension, which defines template function. This change requires that "templatefunc" attribute of (3rd party) extension is registrar.templatefunc or so.

keyword: use templatefilter to mark a function as template filter This patch also adds test for filter 'svnisodate' and 'svnutcdate' for safety, because there is no test using them, yet.

templatefilters: use templatefilter to mark a function as template filter Using decorator can localize changes for adding (or removing) a template filter function in source code. This patch also removes leading ":FILTER:" part in help document of each filters, because using templatefilter makes it useless. This patch uses not 'filter' but 'templatefilter' as a decorator name, because the former name hides Python built-in one, even though the latter is a little redundant in 'templatefilters.py'.

registrar: add templatefilter to mark a function as template filter (API) This patch also adds loadfilter() to templatefilters, because this combination helps to figure out how they cooperate with each other. Listing up loadfilter() in dispatch.extraloaders causes implicit loading template filter functions at loading (3rd party) extension. This change requires that "templatefilter" attribute of (3rd party) extension is registrar.templatefilter or so.

revset: inline _getaliasarg() function This function is now much simpler than before. Inlining small functions helps to extract a reusable alias processor.

revset: drop redundant check for unknown alias arguments Since _parsealiasdefn() rejects unknown alias arguments, _checkaliasarg() is unnecessary. New test is added to make sure unknown '$n' symbols are rejected.

revset: move tagging of alias arguments from tokenization to parsing phase In short, this patch moves the hack from tokenizedefn() to _relabelaliasargs(), which is called after parsing. This change aims to eliminate tight dependency on the revset tokenizer. Before this patch, we had to rewrite an alias argument to a pseudo function: "$1" -> "_aliasarg('$1')" ('symbol', '$1') -> ('function', ('symbol', '_aliasarg'), ('string', '$1')) This was because the tokenizer must generate tokens that are syntactically valid. By moving the process to the parsing phase, we can assign a unique tag to an alias argument. ('symbol', '$1') -> ('_aliasarg', '$1') Since new _aliasarg node never be generated from a user input, we no longer have to verify a user input at findaliases(). The test for _aliasarg("$1") is removed as it is syntactically valid and should pass the parsing phase.

revset: add test that should fail if '_aliasarg' tag is removed I'm going to refactor the alias processing functions. We need '_aliasarg' tag to limit the scope of the alias expansion, but it wasn't covered by the test. This patch adds the test that should fail if '_aliasarg' were 'symbol'. This is the first half of the second part of the "template alias" series. The whole series will consist of the following parts: 1. make parsed template tree to be compatible with parser functions (1d461ee26e1b and 73d01cba5810) 2. refactor alias processing to be less dependent on revset module (1/2 in this series) 3. extract reusable component to parser module 4. clean up it 5. extend it to support template syntax 6. add debugging/testing functions of template aliases 7. add alias expansion routine to templater

templater: do not strip non-quote characters from template config Before this patch, the first and last characters were stripped from ui.logtemplate and template.* if they were the same. It could lead to a strange result as quotes are optional. See the test for example.

rebase: fix crash when rebase aborts while rebasing obsolete revisions Before this patch, rebase --continue would crash when trying to resume a rebase of obsolete revisions whose successors were in the destination. This patch adds logic to recompute the mapping when rebase is resumed. This patch also adds a test that showcased the crash before the code change.
