connection: reimplement timeout logic and redefine pings as a keep-alive feature · 737e227a

Julien Muchembled authored May 27, 2011

- Previous implementation was not able to import transactions with many small
  objects, the client for faster to send a store request than to process its
  answer. If X is the difference of time for these 2 operations, the maximum
  number of objects a transaction could contain was CRITICAL_TIMEOUT / X.
  And HasLock feature can't act as a workaround because it is not working yet.
- Change API of 'on_timeout', which currently only used by HasLock.
- Stop pinging when we wait for an answer. This wastes resources and would
  never recover any bad state.
- Make client connections send pings when they are idle instead.
  This implements keep-alive feature for high availability.
  Start with an non-configurable period of 60 seconds.
- Move processing of ping/pong to handlers.

poll: data may be received when processing exception list · 86ce8602

Julien Muchembled authored May 27, 2011

For the moment, this only fixes a performance issue because in the worst case,
subsequent pings (every 6 seconds) would make _poll() check in the connection
has any pending message (while processing 'rlist').

Revert to single-dist setup.py and use virtual dependencies instead · 6e1932bd

Julien Muchembled authored May 23, 2011

The only reason why we produced different eggs was because we may want to
install easily an admin node without caring about dependencies of neo.client.

Multi-dist setup.py contains hacks and was overkill for NEO.

Full review of packaging, with multi-eggs setup.py · 185dffa0

- multi-eggs setup.py because we really don't want to split the repository

- move 'components.xml' since namespace packages should not contain anything
- workaround python-mock.sf.net because not eggified:
  automatically get a copy of mock.py (license: BSD) when setting up 'neotests'

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.
