If you run a pyblosxom blog with auto-copied stories from SVN you are probably interested in getting stable story dates that don't change every time you update a story. The date of the initial SVN log entry of a story is something like the "day of birth" of a story, so it's a good value to use. Christopher Baus implemented a plugin for pyblosxom, which looks overly complicated to me: it depends on memcached and comes in two large python scripts.
To simplify things I wrote this minimal replacement:
import pysvn, os, sys, anydbm from config import py def get_mtime(fname): cache_fname = os.path.join(py['datadir'], 'SVNDATES') cache = anydbm.open(cache_fname, "c") if cache.has_key(fname): d = float(cache[fname]) else: client = pysvn.Client(fname) l = client.log(fname) if len(l) > 0: d = l['date'] cache[fname] = str(d) else: d = -1 del client del cache return d def cb_filestat(args): args["mtime"] = list(args["mtime"]) d = get_mtime(args["filename"]) if d >= 0: args["mtime"] = d return args
Since accessing SVN logs is quite slow the script caches the "date of birth" in a dbm file. Make sure that your web server has enough priviliges to access that database file which is stored in $datadir/SVNDATES by default.
