import-checker: parse python code from .t files

import-checker: track filenames for SyntaxErrors

import-checker: track SyntaxErrors We don't really need to report SyntaxErrors, since in theory docchecker or a test will catch them, but they happen, and we can't just have the code crash, so for now, we're reporting them.

import-checker: refactor source reading This will allow .t files to generate multiple sources. It will also allow .py doctests to generate additional sources.

tests: make test-pathencode use print_function

tests: make test-run-tests use absolute_import

tests: make test-symlink-os-yes-fs-no use absolute_import

tests: make test-url use absolute_import

templater: add parsing and expansion rules to process "templatealias" section The debugtemplate command is updated to show expanded tree, but still the template engine doesn't support alias expansion. That's why the test says "parse error" for now.

templater: add function to parse whole string as template expression This will be a parser of template aliases, and it can also be used for processing quoted string templates in map files. That's why this function isn't defined in the upcoming _aliasrules class.

parser: factor out _trygetfunc() that extracts function name and arguments This provides a customization point for templater. In templater, there are two ways to call a unary function: func(x) and x|func. They are processed differently in templater due to historical reasons, but they should be handled in the same way while expanding aliases. In short, x|func should be processed as syntactic sugar for func(x). _funcnode and _getlist() are replaced by _trygetfunc().

parser: make _getalias() return (alias, pattern-args) pair This allows us to factor out a function that extracts a function (name, args) pair. See the next patch for why.

parser: drop redundant comparison between alias declaration tree and pattern Since _getalias() explicitly tests the type and name of the pattern tree, we don't need to compare "a.tree == tree" for 'symbol', and "a.tree == tree[:2]" for 'func', where tree is either ('symbol', name) or ('func', ('symbol', name)). This change helps implementing better handling of template aliases. See the subsequent patches for details. The alias.tree field is removed as it is no longer used.

patchbomb: fix public-is-missing hint Without this, there is no space between a hash and the -r preceding the next line in the use hg push hint

tests: clarify patchbomb repo is public not remote

run-tests: set HGMODULEPOLICY for --pure Without this, my python 2.6 virtualenv test run with --pure and --local fails with: + ImportError: Python minor version mismatch: The Mercurial extension modules were compiled with Python 2.7.8, but Mercurial is currently using Python with sys.hexversion=33950192: Python 2.6.9 (unknown, Apr 13 2016, 12:40:12) + [GCC 4.9.2 20141101 (Red Hat 4.9.2-1)] + at: ~/hg/py26/bin/python

cmdutil: avoid recycling variable name "name" in namespaces code This just feels like asking for future trouble and confusion.

update: fix bare update to work on new branch So far bare update on new branch results in 'abort: branch new-branch not found'. This commit fixes this by updating to the parent of wctx. The effect of updating to the parent of wctx is to move to the paren't branch - this means that it is no longer necessary to prevent you from updating if you would lose your newly created branch.

remove: fix --force option help description (issue5177) Before this commit --force option help description stated that file was removed and deleted even if file was added or modified which is not true. Force option removes added file only from dirstate, it doesn't delete it from the filesystem.

logtoprocess: new experimental extension This extension lets you direct specific ui.log() information to shell commands, spawned in the background. This can be used to, say, capture timings, commandfailure tracebacks, etc., making the output available to other command-line tools.

convert: keep converted hg parents that are outside convert.hg.revs (BC) Before, when converting revisions without also including their already converted parents in convert.hg.revs, the parents would no longer be parents. That seems unfortunate and we dare to assume that nobody ever wants that. Instead, preserve parents that are outside the current convert range but already have been converted. The parents returned in getcommit() are unconditionally converted, so we introduce a separate optparents with optional parents.

tests: coverage of ancestry with convert in multiple non-overlapping steps This exposes that parent information is lost in cases where it is possible to preserve it - and where it thus would make sense if that was what happened.

revset: rename findaliases() to expandaliases() This function returns a full tree of alias expansion applied, which sounds different from what "findaliases" would do.

parser: add short comment how aliases are expanded in phases

parser: reorder alias expansion routine to return early I think it improves readability to move trivial cases first, and unindent blocks.

parser: move functions that process alias expansion to rule-set class They will be commonly used by revset and templater. It isn't easy to understand how _expand() works, so I'll add comments by a follow-up patch. The local variable 'alias' is renamed to 'a' to avoid shadowing the global 'alias' class.
