subrepo: drop the 'ui' parameter to cat()
This no longer needs to be explicitly passed because the subrepo object tracks
a 'ui' reference since fcbc66b5da6a. See the change to 'archive' for details
about the differences between the output level in the root repo and subrepo 'ui'
object.
The only use for 'ui' in cat is to emit a status message when a subrepo is
missing. The bad() method on the matcher still uses the root repo's ui, because
narrowing the matcher doesn't change the ui object.

'''perform automatic newline conversion (DEPRECATED) Deprecation: The win32text extension requires each user to configure the extension again and again for each clone since the configuration is not copied when cloning. We have therefore made the ``eol`` as an alternative. The ``eol`` uses a version controlled file for its configuration and each clone will therefore use the right settings from the start. To perform automatic newline conversion, use:: [extensions] win32text = [encode] ** = cleverencode: # or ** = macencode: [decode] ** = cleverdecode: # or ** = macdecode: If not doing conversion, to make sure you do not commit CRLF/CR by accident:: [hooks] pretxncommit.crlf = python:hgext.win32text.forbidcrlf # or pretxncommit.cr = python:hgext.win32text.forbidcr To do the same check on a server to prevent CRLF/CR from being pushed or pulled:: [hooks] pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf # or pretxnchangegroup.cr = python:hgext.win32text.forbidcr ''' from mercurial.i18n import _ from mercurial.node import short from mercurial import util import re testedwith = 'internal' # regexp for single LF without CR preceding. re_single_lf = re.compile('(^|[^\r])\n', re.MULTILINE) newlinestr = {'\r\n': 'CRLF', '\r': 'CR'} filterstr = {'\r\n': 'clever', '\r': 'mac'} def checknewline(s, newline, ui=None, repo=None, filename=None): # warn if already has 'newline' in repository. # it might cause unexpected eol conversion. # see issue 302: # http://mercurial.selenic.com/bts/issue302 if newline in s and ui and filename and repo: ui.warn(_('WARNING: %s already has %s line endings\n' 'and does not need EOL conversion by the win32text plugin.\n' 'Before your next commit, please reconsider your ' 'encode/decode settings in \nMercurial.ini or %s.\n') % (filename, newlinestr[newline], repo.join('hgrc'))) def dumbdecode(s, cmd, **kwargs): checknewline(s, '\r\n', **kwargs) # replace single LF to CRLF return re_single_lf.sub('\\1\r\n', s) def dumbencode(s, cmd): return s.replace('\r\n', '\n') def macdumbdecode(s, cmd, **kwargs): checknewline(s, '\r', **kwargs) return s.replace('\n', '\r') def macdumbencode(s, cmd): return s.replace('\r', '\n') def cleverdecode(s, cmd, **kwargs): if not util.binary(s): return dumbdecode(s, cmd, **kwargs) return s def cleverencode(s, cmd): if not util.binary(s): return dumbencode(s, cmd) return s def macdecode(s, cmd, **kwargs): if not util.binary(s): return macdumbdecode(s, cmd, **kwargs) return s def macencode(s, cmd): if not util.binary(s): return macdumbencode(s, cmd) return s _filters = { 'dumbdecode:': dumbdecode, 'dumbencode:': dumbencode, 'cleverdecode:': cleverdecode, 'cleverencode:': cleverencode, 'macdumbdecode:': macdumbdecode, 'macdumbencode:': macdumbencode, 'macdecode:': macdecode, 'macencode:': macencode, } def forbidnewline(ui, repo, hooktype, node, newline, **kwargs): halt = False seen = set() # we try to walk changesets in reverse order from newest to # oldest, so that if we see a file multiple times, we take the # newest version as canonical. this prevents us from blocking a # changegroup that contains an unacceptable commit followed later # by a commit that fixes the problem. tip = repo['tip'] for rev in xrange(len(repo) - 1, repo[node].rev() - 1, -1): c = repo[rev] for f in c.files(): if f in seen or f not in tip or f not in c: continue seen.add(f) data = c[f].data() if not util.binary(data) and newline in data: if not halt: ui.warn(_('attempt to commit or push text file(s) ' 'using %s line endings\n') % newlinestr[newline]) ui.warn(_('in %s: %s\n') % (short(c.node()), f)) halt = True if halt and hooktype == 'pretxnchangegroup': crlf = newlinestr[newline].lower() filter = filterstr[newline] ui.warn(_('\nTo prevent this mistake in your local repository,\n' 'add to Mercurial.ini or .hg/hgrc:\n' '\n' '[hooks]\n' 'pretxncommit.%s = python:hgext.win32text.forbid%s\n' '\n' 'and also consider adding:\n' '\n' '[extensions]\n' 'win32text =\n' '[encode]\n' '** = %sencode:\n' '[decode]\n' '** = %sdecode:\n') % (crlf, crlf, filter, filter)) return halt def forbidcrlf(ui, repo, hooktype, node, **kwargs): return forbidnewline(ui, repo, hooktype, node, '\r\n', **kwargs) def forbidcr(ui, repo, hooktype, node, **kwargs): return forbidnewline(ui, repo, hooktype, node, '\r', **kwargs) def reposetup(ui, repo): if not repo.local(): return for name, fn in _filters.iteritems(): repo.adddatafilter(name, fn) def extsetup(ui): if ui.configbool('win32text', 'warn', True): ui.warn(_("win32text is deprecated: " "http://mercurial.selenic.com/wiki/Win32TextExtension\n"))
