Summary:
This check is useful and detects real errors (ex. fbconduit). Unfortunately
`arc lint` will run it with both py2 and py3 so a lot of py2 builtins will
still be warned.
I didn't find a clean way to disable py3 check. So this diff tries to fix them.
For `xrange`, the change was done by a script:
```
import sys
import redbaron
headertypes = {'comment', 'endl', 'from_import', 'import', 'string',
'assignment', 'atomtrailers'}
xrangefix = '''try:
xrange(0)
except NameError:
xrange = range
'''
def isxrange(x):
try:
return x[0].value == 'xrange'
except Exception:
return False
def main(argv):
for i, path in enumerate(argv):
print('(%d/%d) scanning %s' % (i + 1, len(argv), path))
content = open(path).read()
try:
red = redbaron.RedBaron(content)
except Exception:
print(' warning: failed to parse')
continue
hasxrange = red.find('atomtrailersnode', value=isxrange)
hasxrangefix = 'xrange = range' in content
if hasxrangefix or not hasxrange:
print(' no need to change')
continue
# find a place to insert the compatibility statement
changed = False
for node in red:
if node.type in headertypes:
continue
# node.insert_before is an easier API, but it has bugs changing
# other "finally" and "except" positions. So do the insert
# manually.
# # node.insert_before(xrangefix)
line = node.absolute_bounding_box.top_left.line - 1
lines = content.splitlines(1)
content = ''.join(lines[:line]) + xrangefix + ''.join(lines[line:])
changed = True
break
if changed:
# "content" is faster than "red.dumps()"
open(path, 'w').write(content)
print(' updated')
if __name__ == "__main__":
sys.exit(main(sys.argv[1:]))
```
For other py2 builtins that do not have a py3 equivalent, some `# noqa`
were added as a workaround for now.

This makes sure that all columns are aligned. getlogcolumns() is hosted by
templatekw so the namespaces module can see it.
i18n/de.po is updated so test-log.t passes with no error. "obsolete:" and
"instability:" are kept untranslated.
We do "'%d:%s' % (ctx...)" at several places, so let's formalize it. A low-
level function, formatrevnode(ui, rev, node), is extracted so we can pass
a manifest rev/node pair.
Note that hex() for manifest output can be replaced with hexfunc() because
it is printed only when debugflag is set.
i18n/de.po is updated so test-log.t passes with no error.
Before this patch, source filename for msgid in hg.pot file becomes
incorrect, if a function is defined in file A, but detected in dict in
file B,
For example, almost all debug* commands are defined in
debugcommands.py, but hggettext detects them in "table" of
commands.py. Therefore, docstring fragments of debug* commands are
marked as "defined in commands.py" in hg.pot file.
This is serious problem for translation, because the cost to find out
original location of texts increases very much.
Docstring of modules is needed only for "hg help -e EXTNAME".
This is a preparation for applying hggettext on util.py, which has
module docstring, but it isn't needed for translation.
To list up available compression types instead of
".. bundlecompressionmarker" in "hg help bundlespec" output, proxy
object "docobject" is used, because:
- current online help system requires that __doc__ of registered
object (maybe, function) is already well formatted in reST syntax
- bundletype() method of compressionengine classes is used to list up
available compression types, but
- __doc__ of bundletype() object (= "instancemethod") is read-only
On the other hand, hggettext requires original function object, in
order to get document location in source code.
Therefore, description of each compression types isn't yet
translatable. Even if translatable, translators should make much
effort to determine location of original texts in source code.
To get actual function information, this patch makes hggettext use
function object saved as "_origfunc", if it is available. This patch
also changes bundlecompressiontopics() side, in order to explain how
these changes work easily.
This patch is a part of preparations for making description of each
compression types translatable.
hggettext assumes that backslashes in docstring are always doubled in
original source code, in order to find the location of original
docstring out certainly.
This assumption almost always works as expected. But doctest easily
breaks it, because many of backslashes in doctests aren't doubled.
This mismatching causes "unknown offset in ..." warning at "make
update-pot".
To avoid such warning, this patch ignores doctest part of docstring
before finding the location of original docstring out.
BTW, at this patch, only person() in templatefilters.py has doctest
part, which causes "unknown offset ..." warning.
Therefore, just making backslashes in that doctest doubled can avoid
such warning, too. But forcing doctest writers to double backslashes
in doctest isn't reasonable, IMHO.
Before this patch, hggettext uses __doc__ of each functions to compute
offset of document text.
But __doc__ of many functions is already modified by decorators in
registrar (e.g. @templatekeyword adds ":NAME: " prefix to it), and
hggettext can not find it out in original source.
This causes many "unknown offset in ..." warning at "make update-pot",
and leaving them might cause overlooking serious problems.
This patch makes hggettext use original docstring, which decorators in
registrar save into _origdoc, to compute offset.
Even after this patch, there are still a few "unknown offset in ..."
warning at "make update-pot" for specific reasons. These will be fixed
later one by one.
These are all simple one-argument print statements, so this syntax
works the same way in 2 and 3.

This patch replaces domain of mercurial-devel ML address by
mercurial-scm.org for "Report-Msgid-Bugs-To" property of each *.po
files.
This avoids releasing 4.1.1 with invalid "Report-Msgid-Bugs-To"
in *.mo file, if corresponded *.po file isn't msgmerge-ed with recent
hg.pot by translator.
These *.po files aren't covered by check-code.py pattern newly added
in subsequent patch, because it ignores them.
This patch includes addition of absolute_import and print_function to the
files where they are missing. The modern importing conventions are also followed.
