From: schlatterbeck Date: Thu, 7 Oct 2010 12:22:10 +0000 (+0000) Subject: - refactor: move import_journal to hyperdb -- it was reimplemented in X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=ed1f70d9af02711dafa92e950fc9bb79a23548f2;p=roundup.git - refactor: move import_journal to hyperdb -- it was reimplemented in back_anydbm and rdbms_common and was already inconsistent -- and it doen't have any backend dependencies itself. Interestingly this now fails a test for memorydb (but passes for anydbm: Huh?) git-svn-id: http://svn.roundup-tracker.org/svnroot/roundup/roundup/trunk@4538 57a73879-2fb5-44c3-a270-3262357dd7e2 --- diff --git a/CHANGES.txt b/CHANGES.txt index 246023e..0121458 100644 --- a/CHANGES.txt +++ b/CHANGES.txt @@ -44,8 +44,7 @@ Fixed: Thanks to Benni Bärmann for reporting. - Allow search_popup macro to work with all db classes, issue2550567 (thanks John Kristensen) -- lower memory footprint for (journal-) import -- only for rdbms - backends, other backends shouldn't have that much data anyway. +- lower memory footprint for (journal-) import 2010-07-12 1.4.15 diff --git a/roundup/backends/back_anydbm.py b/roundup/backends/back_anydbm.py index 463a43f..3d132ec 100644 --- a/roundup/backends/back_anydbm.py +++ b/roundup/backends/back_anydbm.py @@ -2000,34 +2000,6 @@ class Class(hyperdb.Class): repr(action), repr(params)]) return r - def import_journals(self, entries): - """Import a class's journal. - - Uses setjournal() to set the journal for each item.""" - properties = self.getprops() - d = {} - for l in entries: - nodeid, jdate, user, action, params = tuple(map(eval, l)) - r = d.setdefault(nodeid, []) - if action == 'set': - for propname, value in params.iteritems(): - prop = properties[propname] - if value is None: - pass - elif isinstance(prop, hyperdb.Date): - value = date.Date(value) - elif isinstance(prop, hyperdb.Interval): - value = date.Interval(value) - elif isinstance(prop, hyperdb.Password): - pwd = password.Password() - pwd.unpack(value) - value = pwd - params[propname] = value - r.append((nodeid, date.Date(jdate), user, action, params)) - - for nodeid, l in d.iteritems(): - self.db.setjournal(self.classname, nodeid, l) - class FileClass(hyperdb.FileClass, Class): """This class defines a large chunk of data.
