This code uses the ast module, which was new in 2.6, so we'll skip
|
|
|
|
|
this test on anything earlier.

Run the doctests from the import checker, and make sure

|
|

it's working correctly.

There are a handful of cases here that require renaming a module so it
|
|
|
|
|
doesn't overlap with a stdlib module name. There are also some cycles
|
|
|
|
|
here that we should still endeavor to fix, and some cycles will be
|
|
|
|
|
hidden by deduplication algorithm in the cycle detector, so fixing
|
|
|
|
|
these may expose other cycles.

template: add revset() template function
Adds a template function that executes a revset and returns the list of
revisions as the result. It has the signature 'revset(query [, args...])'. The
args are optional and are applied to the query string using the standard
python string.format(args) pattern. This allows things like:
'{revset("parents({0})", rev)}' to produce the parents of each individual
commit in the log output. If no args are specified, the revset result is
cached for the duration of the templater; so it's better to not use args if
performance is a concern.
By itself, revset() can be used to print commit parents, print the common
ancestor of a commit with the main branch, etc.
It can be used with the ifcontains() function to do things like
'{ifcontains(rev, revset('.'), label(...), ...)}' to color the working copy
parent, to color certain branches, to color draft commits, etc.

import-checker: make imported_modules yield absolute dotted_name_of_path
This patch makes `imported_modules()` always yield absolute
`dotted_name_of_path()`-ed name by strict detection with
`fromlocal()`.
This change improves circular detection in some points:
- locally defined modules, of which name collides against one of
standard library, can be examined correctly
For example, circular import related to `commands` is overlooked
before this patch.
- names not useful for circular detection are ignored
Names below are also yielded before this patch:
- module names of standard library (= not locally defined one)
- non-module names (e.g. `node.nullid` of `from node import nullid`)
These redundant names decrease performance of circular detection.
For example, with files at 13dc86d189c9, average loops per file in
`checkmod()` is reduced from 165 to 109.
- `__init__` can be handled correctly in `checkmod()`
For example, current implementation has problems below:
- `from xxx import yyy` doesn't recognize `xxx.__init__` as imported
- `xxx.__init__` imported via `import xxx` is treated as `xxx`,
and circular detection is aborted, because `key` of such
module name is not `xxx` but `xxx.__init__`
- it is easy to enhance for `from . import xxx` style or so (in the
future)
Module name detection in `imported_modules()` can use information
in `ast.ImportFrom` fully.
It is assumed that all locally defined modules are correctly specified
to `import-checker.py` at once.
Strictly speaking, when `from foo.bar.baz import module1` imports
`foo.bar.baz.module1` module, current `imported_modules()` yields only
`foo.bar.baz.__init__`, even though also `foo.__init__` and
`foo.bar.__init__` should be yielded to detect circular import
exactly.
But this limitation is reasonable one for improvement in this patch,
because current `__init__` files in Mercurial seems to be implemented
carefully.
