13
14 - listener-less nodes had trouble sending keepalive
15 messages on write timeouts (found by Sadrak).
16 - the monitor guard could cause a memleak due
17 to autovivification if a mon was cleared after
18 the port was gone (analysed by Sadrak).
19
20 1.28 Thu Apr 1 21:23:54 CEST 2010
21 - accepted conenctions didn't corretcly set up the SRCNODE
22 in some cases, leading to intra-node messages (such as monitoring)
23 to fail silently (great testcase by Sadrak).
24
25 1.27 Sat Mar 20 21:11:16 CET 2010
26 - avoid exceptions in the transport code if the connection
27 fails during TLS negotiation.
28 - delay new address broadcasts in seednodes, to reduce the
29 likelyhood of nodes connecting at the same time, leading to
30 message loss.
31 - improve general message passing efficiency by 8%, and special
32 case json framing for a 50% speed increase.
33 - add hints how to interface to aemp nodes from other programming
34 languages using the aemp protocol in AnyEvent::MP::Transport
35 (it can really be quite simple).
36 - handle unsupported remote framings more gracefully.
37
38 1.26 Wed Dec 30 16:48:37 CET 2009
39 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
40 all nodes need to upgrade.
41 - remote kil's did not work (reported by Eugene Grigoriev).
42 - documented monitor_timeout, connect_interval, auth_offer,
43 auth_accept, framing_format, autocork and nodelay options
44 and make them configurable via bin/aemp.
45 - some doc updates.
46 - remote kil's were not synchronous to message sends which affected
47 nobody, as remote kils were broken.
48 - remote mon/unmonitor requests were not synchronous to message
49 sends either sometimes, although it likely didnt matter.
50
51 1.24 Wed Dec 9 14:59:52 CET 2009
52 - codename "the foul egg".
53 - increased "unmonitored local port died" message level to 2, so
54 it is displayed by default now.
55 - generate random seed at configure time, not module loading time,
56 so fork&configure works as expected.
57 - decreased "seed"-related message priority in Global from 0 (d'oh)
58 to 9, as they are not signifcant.
59 - new experimental module AnyEvent::MP::DataConn to establish
60 additional data connections between nodes.
61 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
62 to call restart.
63 - bin/aemp setcert didn't properly handle the filename argument.
64 - removed empty and unused timeout= parameter from protocol greeting.
65
66 1.23 Fri Nov 6 18:46:26 CET 2009
67 - listener-less nodes were misinformed by their masters about
68 the location of new nodes, and therefore didn't connect
69 properly in all cases.
70 - messages send during node-up processing could sometimes get lost,
71 which would hamper global's ability to mesh the network.
72 - fixed AnyEvent::MP::Global::grp_reg to return a guard also
73 in scalar context.
74 - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
75 in scalar context.
76 - try to improve error reporting when automatically loading
77 a function - being unable to load a module will now
78 stop the process and report the error.
79
80 1.22 Sat Oct 17 03:41:47 CEST 2009
81 - fix two rcv-bugs: after adding a tagged rcv, the default
82 callback would not be used or changed anymore (reported
83 by Felix Antonius Wilhelm Ostmann, with apologies for
84 taking so long to releae the fix).
85 - added Coro::MP introduction to AnyEvent::MP::Intro.
86 - add peval function.
87
88 1.21 Mon Oct 5 21:58:36 CEST 2009
89 - always delay kil messages.
90 - remote monitor requests were never cleaned up (found by
91 Sadrak and analysed by elmex).
92 - move $VERSION to AnyEvent::MP and AnyEvent::MP only.
93
94 1.2 Thu Oct 1 22:59:35 CEST 2009
95 - fix a rather big bug where message processing could be
96 inhibited completely.
97 - grp_mon could not return a guard due to a typo.
98 - implement primitive aemp shell.
99 - do not use bound address as listen length (reported by
100 Felix Antonius Wilhelm Ostman).
101 - no longer export an undefined "reg" function from AE::MP.
102 - the mon_guard return value no longer keeps an additional
103 reference to the passed refs.
104
105 1.1 Fri Sep 11 04:34:03 CEST 2009
106 - bumped the transport protocol to version 1 - sorry, but there
107 were too many bugfixes/changes.
108 - new function AnyEvent::MP::cal for simple rpc.
109 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
110 - implemented monitoring for Global groups.
111 - removed all userspace time-outs from the transport, instead
112 rely on tcp retransmit timeouts and tcp keepalive.
113 - spawn now delays spawns on the local node artificially, so
114 it can return before invoking the init function.
115 - break endless recursion between ping-pong ports on the local
116 node after ~50 iterations.
117 - support JSON-encoded aemp arguments.
118 - added aemp restart.
119 - support for starting init functions with parameters added.
120 - data_format, auth_offer and auth_accept are now configurable, albeit
121 not documented.
122 - new service: AnyEvent::MP::LogCatcher.
123 - rely on perl srand'ing better than we could.
124 - try to backport to 5.8.2, unfortunately, recursive dependencies
125 rely on Module::Build, which fails at 5.8.7, so YMMV.
126 - use a vastly different reseeding strategy.
127 - use seed nodes to notify nodes about new nodes.
128 - in the case where a ndoe learns new addresses after it tried
129 connecting, prefer the new addrseses over the old ones.
130
131 1.0 Wed Sep 2 20:40:43 CEST 2009
132 - randomise more connection times, but reduce delay to 0.2s (seeds)
133 and 0.05s (normal connects).
134 - upgrade to and require AnyEvent::Watchdog 1.0.
135
136 0.95 Mon Aug 31 22:03:55 CEST 2009
137 - tutorial finally covers all the basics, maybe not optimally, but it
138 is covered.
139 - rename initialise_node to configure and accepts key => value
140 pairs for configuration.
141 - give aemp a full manpage.
142 - bin/aemp now expects comma-separated lists and supports multiple
143 subcommands.
144 - new aemp eval subcommand.
145 - new aemp parent subcommand.
146 - nodes get freed when no longer needed.
147 - support "*" hostname to specify all local interface addresses
148 (without localhost etc.).
149 - support "*" port to specify a dynamically-assigned port (which
150 is the default now).
151 - fix per-transport memory leak.
152
153 0.9 Sat Aug 29 18:47:45 CEST 2009
154 - tutorial was updated to reflect the current API, but
155 does not touch monitoring yet.
156 - got rid of noderefs and slave nodes entirely, introduce
157 free-text node identifiers and anonymous nodes.
158 - document security issues with tls_anon method and introduce
159 optional tls_md6_64_256 method.
