- References to headers now involve the package names. - The zpkg support files have been moved to the top-level directory, and the releases/ tree has been removed. The resource map and configuration file have been combined now that zpkg allows that. - The scripts are now all located in src/scripts/ in a checkout. - Scripts that were imported in the tests have been split into library and script components; the library portions share name of the script (in order to reduce changes). The library portions may not be used as scripts directly.

More on collector 1847 (ZEO cache tracing). simul.py hit NameErrors when startup cache verification found data in the cache to invalidate. The cache's loadBefore() implementation called _trace() incorrectly, passing the tid where the version argument belonged.

Part of Collector 1860 (the other part is in Zope). There's no possiblity of rollback here, so no need to insist that the data manager support rollbacks.

Plug leaks in the ZEO client cache. ClientCache._evicted(): When deleting the last range of non-current tids for an oid, remove the list from the noncurrent dict instead of leaving an empty list sitting there forever. This also required adjusting the side- effect dance in ClientCache._remove_noncurrent_revisions(). FileCache._makeroom(): This was the major leak -- it neglected to remove an evicted object's Entry from the key2entry dict.

Removed the `key2size` OIBTree. Maintaining this is a significant expense; the code didn't make real use of it; and every time I've tried to exploit it I've ended up with grossly too-large simulated hit rates. Would probably take another day to figure out exactly why that is, and the simulated rates are "good enough" now without it.

The cache simulation seems good enough to be useful now, although the toy app I wrote to generate a 500MB trace file doesn't use MVCC in an essential way (some of the MVCC simulation code is nevertheless exercised, since an invalidation of current data in the presence of MVCC always creates a cache record for the newly non-current revision). Still puzzling over what to do when the trace file records a load hit but the simulated cache gets a miss. The old simulation code seemed to assume that a store for the same oid would show up in the trace file next, and it could get the info it needed about the missing object from the store trace. But that isn't true: precisely because the load was a hit in the trace file, the object isn't going to be stored again "soon" in the trace file. Here are some actual-vs-simulated hit rate results, for a 20MB cache, with a trace file covering about 9 million loads, over 3 ZEO client (re)starts: actual simulated ------ --------- 93.1 92.7 79.8 79.0 68.0 69.1 81.4 81.1 overall Since the simulated hit rates are both higher and lower than the actual hit rates, that argues against a gross systematic bias in the simulation (although there may be several systematic biases in opposite directions).

Massive rewrite to make simul.py's circular cache aware of MVCC. It isn't blowing up, but it thinks the hit rate is 100% -- might have missed something there <wink>.

More steps on the way toward having useful cache simulation. I think the primary hangup now is that simul.py doesn't know anything about MVCC. As a result, it thinks there's significatly more free space in the cache than there really is, and that probably accounts for it predicting significantly higher hit rates than I actually see.

Lots of fiddling to work w/ current trace file format. Output isn't obviously wholly insane, but isn't a reasonably close enough match to stats.py output either yet.

stats.py: cut the # of file reads by 1/3, and the # of struct.unpack() calls by 1/2. Various bugfixes elsewhere.

Tim Peters authored
Many little bugfixes and improvements in stats.py. This has survived several 100 MB of trace files I generated over the last few days, so it's solid now if not necessarily perfect. Replaced simul.py with the much broader-ranging code Jeremy and I were working on a couple years ago, although it can't work with the current trace file format (no real loss there -- the simul.py it's replacing can't work with the current format either).

Stitch in ZConfig's docs from ZConfig.

Tim Peters authored
Remove this -- it's a way out-of-date copy of the ZConfig docs. I'll stitch them back in from the ZConfig repo next, via svn:externals. Ideally, ZODB shouldn't have this as part of its checkout tree at all, but that also has implications for the way ZRS gets packaged, etc.

A large number of changes so that cache tracing isn't 100% broken -- I can get a trace file now, and stats.py doesn't blow up anymore. Don't yet know whether it's reporting sensible things, but it's not obviously insane. simul.py doesn't know about the current cache implementation either yet.

ClientCache: made it a new-style class. FileCache: Removed the reuse= argument. IIRC, it made some sense when different cache schemes were first being tried, but complicated the logic now to no good end. Nuked the maddening log warnings about reuse=True. They were never helpful and were often confusing. Added info-level log messages to record the path of the client cache file, whether it's persistent or temporary, and if it's persistent whether we're creating or reusing it. Minor changes to comments.

Collector 1843: IISet.keys: bad exception handling. Bucket_rangeSearch(): De-obfuscated the calls to Bucket_findRangeEnd(), so that they stop ignoring the latter's error returns (a mind-bending combination of embedded assignment nested in an UNLESS macro, seemingly copy+paste'd so that the error occurred twice).

Port from ZODB 3.2. Collector #1846: If an uncommitted transaction was found, fsrecover.py fell into an infinite loop. Fixed that, and added a new test (testUncommittedAtEnd) to ensure this stays fixed.
