Split testRestartWithMissingStorage into 1 passing and 1 failing tests · c21ad524

Julien Muchembled authored Apr 28, 2011

testRestartWithMissingStorage was failing randomly depending on whether the
cluster was started before or after the storage initializing connection
with the master.
Change to NEOCluster.start allows to test both scenarios explicitely.

connection: make close always call handler (connectionClosed or connectionFailed) · 4b6c1387

Julien Muchembled authored Apr 27, 2011

Main reason is that it's difficult to know in advance which side really closes
the connection. Network events can be chaotic and this could lead to many race
conditions.
Thus, handler can be used to update any database that is somewhat redundant
to the connection status, i.e. node status usually. Safely and less duplicated
code.

This change is motivated by recurrent random failures during election.
An example of race condition was that 2 fully connected master could close the
extra connection (the primary -> secondary one) at the same time.

In order to stabilize lower-level code and start with reliable election process,
code has also been simplified to not care about node states. All connections
without exception are closed at the end of the election and states are then
updated 1 by 1 by identification handler.
Note that during election, there may be 2 connection per node, which makes
difficult to update node states by connectionFailed/connectionClosed events.

timeoutExpired & peerBroken are dropped as they are unused for the moment.
A new API should be designed so that connectionClosed know the reason of the
close.
BROKEN state becomes unused.

Rewrite storage cache of client · edde1fe3

Julien Muchembled authored Apr 12, 2011

- Stop using a list of (in)validated tid (hence removal of RevisionIndex),
  because it can't work in all cases and would even cause memory leaks.
  For example, this bug could lead to ConflictError with a single client.
  Fixit it also requires that database backends always return the next serial.
- Several performance improvements. The most important one is when the latest
  version of an object is cached: it inherits the access counter of the
  previous one (for the same oid), which gets in turn its counter reset.
- Do not waste CPU evaluating the real size taken by an entry in memory.
  Just use 'len' on the value (which is always a pickle data, i.e. a string).
