Ticket #1474: improve-check-interfaces.darcs.patch

4 patches for repository davidsarah@dev.allmydata.org:/home/darcs/tahoe/trunk:

Thu Sep 15 17:15:32 BST 2011  david-sarah@jacaranda.org
  * Add a script 'misc/coding_tools/check-interfaces.py' that checks whether zope interfaces are enforced. Also add 'check-interfaces', 'version-and-path', and 'code-checks' targets to the Makefile. fixes #1474

Fri Sep 16 22:26:24 BST 2011  david-sarah@jacaranda.org
  * misc/coding_tools/check-interfaces.py: reduce false-positives by adding Dummy* to the set of excluded classnames, and bench-* to the set of excluded basenames. refs #1474

Fri Sep 16 22:26:33 BST 2011  david-sarah@jacaranda.org
  * misc/coding_tools/check_interfaces.py: use os.walk instead of FilePath, since this script shouldn't really depend on Twisted. refs #1474

Fri Sep 16 23:34:50 BST 2011  david-sarah@jacaranda.org
  * misc/coding_tools/check_interfaces.py: report all violations rather than only one for a given class, by including a forked version of verifyClass. refs #1474

Brian Warner <warner@lothar.com>**20110909181150
 Ignore-this: da66ee51c894eaa4e862e2dffb458acc
 
 This check needs to be done with each fetch from the storage server, to
 detect when someone has changed the share (i.e. our servermap goes stale).
 Doing it just once at the beginning of retrieve isn't enough: a write might
 occur after the first segment but before the second, etc.
 
 _try_to_validate_prefix() was not removed: it will be used by the future
 check-with-each-fetch code.
 
 test_mutable.Roundtrip.test_corrupt_all_seqnum_late was disabled, since it
 fails until this check is brought back. (the corruption it applies only
 touches the prefix, not the block data, so the check-less retrieve actually
 tolerates it). Don't forget to re-enable it once the check is brought back.

 This is a neat trick to reduce Foolscap overhead, but the need for an

 lost-progress bugs.
 
 Also change test_mutable.FakeStorageServer to tolerate multiple reads of the

 publish:
 * encrypt and encode times are cumulative, not just current-segment
 
 retrieve:
 * same for decrypt and decode times
 * update "current status" to include segment number
 * set status to Finished/Failed when download is complete
 * set progress to 1.0 when complete
 
 More improvements to consider:
 * progress is currently 0% or 100%: should calculate how many segments are
   involved (remembering retrieve can be less than the whole file) and set it
   to a fraction
 * "fetch" time is fuzzy: what we want is to know how much of the delay is not
   our own fault, but since we do decode/decrypt work while waiting for more
   shares, it's not straightforward

 Without this, we get a regression when modifying a mutable file that was
 created with more shares (larger N) than our current tahoe.cfg . The
 modification attempt creates new versions of the (0,1,..,newN-1) shares, but
 leaves the old versions of the (newN,..,oldN-1) shares alone (and throws a
 assertion error in SDMFSlotWriteProxy.finish_publishing in the process).
 
 The mixed versions that result (some shares with e.g. N=10, some with N=20,
 such that both versions are recoverable) cause problems for the Publish code,
 even before MDMF landed. Might be related to refs #1390 and refs #1042.

 The changes in layout.py are mostly concerned with the MDMF share
 format. In particular, we define read and write proxy objects used by
 retrieval, publishing, and other code to write and read the MDMF share
 format. We create equivalent proxies for SDMF objects so that these
 objects can be suitably general.

 A candidate patch for #1429 has a bug when it is using FilePath.is_dir() to detect whether the configured local dir exists and is a directory. FilePath.is_dir() raises exception, instead of returning False, if the thing doesn't exist. This test is to make sure that DropUploader.__init__ raise different exceptions for those two cases.

 of using an extension of the mock.patch() function from the mock library) and
 which unpatches in case of exception.

[immutable/downloader/fetcher.py: fix diversity bug in server-response handling
warner@lothar.com**20110227011153
 Ignore-this: bcd62232c9159371ae8a16ff63d22c1b
 
 When blocks terminate (either COMPLETE or CORRUPT/DEAD/BADSEGNUM), the
 _shares_from_server dict was being popped incorrectly (using shnum as the
 index instead of serverid). I'm still thinking through the consequences of
 this bug. It was probably benign and really hard to detect. I think it would
 cause us to incorrectly believe that we're pulling too many shares from a
 server, and thus prefer a different server rather than asking for a second
 share from the first server. The diversity code is intended to spread out the
 number of shares simultaneously being requested from each server, but with
 this bug, it might be spreading out the total number of shares requested at
 all, not just simultaneously. (note that SegmentFetcher is scoped to a single
 segment, so the effect doesn't last very long).

 No behavioral changes, just updating variable/method names and log messages.
 The effects outside these three files should be minimal: some exception
 messages changed (to say "server" instead of "peer"), and some internal class
 names were changed. A few things still use "peer" to minimize external
 changes, like UploadResults.timings["peer_selection"] and
 happinessutil.merge_peers, which can be changed later.

 I'm skeptical that the test was proceeding correctly but ran out of time. It seems more likely that it had gotten hung. But if we raise the timeout to an even more extravagant number then we can be even more certain that the test was never going to finish.

 Pass around IServer instance instead of (peerid, rref) tuple. Replace
 "descriptor" with "server". Other replacements:
 
  get_all_servers -> get_connected_servers/get_known_servers
  get_servers_for_index -> get_servers_for_psi (now returns IServers)
 
 This change still needs to be pushed further down: lots of code is now
 getting the IServer and then distributing (peerid, rref) internally.
 Instead, it ought to distribute the IServer internally and delay
 extracting a serverid or rref until the last moment.
 
 no_network.py was updated to retain parallelism.
