Every now and then I face a corruption of the persistent zeo cache, but this is the first time I get this variant.Advertising
The cause is very likely to be a forced shutdown of the box this zope instance was running on, but I thought it would be nice to report the issue. Here's the traceback:: File "/home/sidnei/src/zope/28five/lib/python/ZEO/ClientStorage.py", line 314, in __init__ self._cache.open() File "/home/sidnei/src/zope/28five/lib/python/ZEO/cache.py", line 112, in open self.fc.scan(self.install) File "/home/sidnei/src/zope/28five/lib/python/ZEO/cache.py", line 835, in scan install(self.f, ent) File "/home/sidnei/src/zope/28five/lib/python/ZEO/cache.py", line 121, in install o = Object.fromFile(f, ent.key, skip_data=True) File "/home/sidnei/src/zope/28five/lib/python/ZEO/cache.py", line 630, in fromFile raise ValueError("corrupted record, oid") ValueError: corrupted record, oid I have a copy of the zeo cache file if anyone is interested. What is bad about this problem is that it prevented Zope from starting and there is no obvious clue that removing the persistent zeo cache would cure it, though that's what anyone that has a clue about what he's doing would do *wink*.
It sounds like there should be logic in that code to abandon the cache if a problem is found, much as we abandon file-storage index files if anything seems suspicious. It seems as though persistent caches haven't been a very sucessful feature. Perhaps we should abandon them. Jim -- Jim Fulton mailto:[EMAIL PROTECTED] Python Powered!
