This is needed to simplify making `hg serve -S` paths the same as `hg serve`. Since 301 is permanent and cachable, this is arguably the proper behavior anyway. For example, once Firefox sees a 301, it automatically forwards, without querying the original URL again. Code hosting software may make use of redirects. I only have access to SCM Manager. It uses 302 to access subrepos, so it isn't affected by this. My understanding of the python libraries being used is minimal, and this was inspired by http://www.diveintopython.net/http_web_services/redirects.html. Since `hg serve` doesn't issue redirects, the added tests aren't showing the new redirect functionality yet. But they set a baseline that won't change when redirects are issued. Check-commit complains about the methods with '_', but those names are defined by python. diff --git a/mercurial/hg.py b/mercurial/hg.py --- a/mercurial/hg.py +++ b/mercurial/hg.py @@ -621,6 +621,15 @@ destrepo = destpeer.local() if destrepo: + # Update for 301 redirects + endsrc = srcpeer.url() + if not islocal(endsrc): + abspath = endsrc + + # statichttprepository never sees the 'static-' prefix, so that + # need to be accounted for here. + if origsource.startswith('static-http'): + abspath = 'static-' + abspath template = uimod.samplehgrcs['cloned'] fp = destrepo.vfs("hgrc", "w", text=True) u = util.url(abspath) diff --git a/mercurial/httppeer.py b/mercurial/httppeer.py --- a/mercurial/httppeer.py +++ b/mercurial/httppeer.py @@ -88,12 +88,12 @@ (u.query or u.fragment)) # urllib cannot handle URLs with embedded user or passwd - self._url, authinfo = u.authinfo() + self._url, self._authinfo = u.authinfo() self.ui = ui self.ui.debug('using %s\n' % self._url) - self.urlopener = url.opener(ui, authinfo) + self.urlopener = url.opener(ui, self._authinfo) self.requestbuilder = urlreq.request def __del__(self): @@ -230,6 +230,16 @@ if self._url.rstrip('/') != resp_url.rstrip('/'): if not self.ui.quiet: self.ui.warn(_('real URL is %s\n') % resp_url) + if resp.status == httplib.MOVED_PERMANENTLY: + u = util.url(resp_url.rstrip('/')) + + # The path has auth info on creation.
