22 root 1.118 2
23     - INCOMPATIBLE CHANGE: the node protocol used by this version is not
24 root 1.121 compatible to versions <2 - you have to upgrade all nodes.
25 root 1.124 - INCOMPATIBLE CHANGE: many APIs have changed, see the section
26     "PORTING FROM VERSION 1" in the AnyEvent::MP manpage for details.
27 root 1.121 - AnyEvent::MP::Global is now optional - only seed nodes autoload it
28     and create a fully-meshed network with each other, normal nodes only
29     have to connect to seed nodes, other connections are on-demand.
30 root 1.118 - new "norc" and "force" options for MP::configure to ignore
31     or override the rc file.
32 root 1.116 - move seed code to Kernel.
33 root 1.118 - fixed small typo in MP::Transport.
34     - fix (unused) provider-kv (version sometimes missing).
35     - reduce the default export list of MP::Kernel.
36 root 1.120 - reduced various random delays to zero, as they
37     are hopefully no longer needed with the new global
38     protocol.
39 root 1.122 - do not use GMP for generating alphanumeric strings even when
40     available, use a more tricky algorithm instead.
41 root 1.121 - anonymous node names and remote port names have been shortened
42     considerably.
43 root 1.122 - aemp shell now supports "package" selection and offers an
44     $ECHO port you cna send messages to.
45     - rely on perl rand() instead of using /dev/urandom when available, as
46     hopefully it is random enough.
47 root 1.123 - aemp shell no longer leaks one port per command.
48 root 1.124 - known_nodes is gone, it has little value, use all_nodes as
49     replacement.
50 elmex 1.115
51 root 1.114 1.30 Thu Jun 30 11:30:39 CEST 2011
52     - connection errors at the right time would kill node
53     connections in a bad way (patch by Malcolm Studd).
54 root 1.107
55 root 1.113 1.29 Fri May 7 20:13:39 CEST 2010
56     - codename "Sadrak".
57 root 1.111 - fix error in callback at AnyEvent/MP/Global.pm line 339
58     (found by Sadrak).
59 root 1.108 - listener-less nodes had trouble sending keepalive
60 root 1.109 messages on write timeouts (found by Sadrak).
61     - the monitor guard could cause a memleak due
62     to autovivification if a mon was cleared after
63     the port was gone (analysed by Sadrak).
64 root 1.112 - do not overwrite the config file if we couldn't read it
65     for some reason (lesson demonstrated by Sadrak).
66 root 1.108
67 root 1.106 1.28 Thu Apr 1 21:23:54 CEST 2010
68 root 1.111 - accepted connections didn't correctly set up the SRCNODE
69 root 1.106 in some cases, leading to intra-node messages (such as monitoring)
70     to fail silently (great testcase by Sadrak).
71    
72 root 1.105 1.27 Sat Mar 20 21:11:16 CET 2010
73 root 1.101 - avoid exceptions in the transport code if the connection
74     fails during TLS negotiation.
75 root 1.102 - delay new address broadcasts in seednodes, to reduce the
76 root 1.103 likelyhood of nodes connecting at the same time, leading to
77 root 1.102 message loss.
78 root 1.104 - improve general message passing efficiency by 8%, and special
79     case json framing for a 50% speed increase.
80 root 1.99 - add hints how to interface to aemp nodes from other programming
81     languages using the aemp protocol in AnyEvent::MP::Transport
82     (it can really be quite simple).
83 root 1.100 - handle unsupported remote framings more gracefully.
84 root 1.99
85 root 1.98 1.26 Wed Dec 30 16:48:37 CET 2009
86 root 1.94 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
87     all nodes need to upgrade.
88 root 1.93 - remote kil's did not work (reported by Eugene Grigoriev).
89 root 1.94 - documented monitor_timeout, connect_interval, auth_offer,
90     auth_accept, framing_format, autocork and nodelay options
91     and make them configurable via bin/aemp.
92 root 1.96 - some doc updates.
93     - remote kil's were not synchronous to message sends which affected
94     nobody, as remote kils were broken.
95 root 1.97 - remote mon/unmonitor requests were not synchronous to message
96     sends either sometimes, although it likely didnt matter.
97 root 1.92
98 root 1.91 1.24 Wed Dec 9 14:59:52 CET 2009
99 root 1.87 - codename "the foul egg".
100     - increased "unmonitored local port died" message level to 2, so
101     it is displayed by default now.
102 root 1.89 - generate random seed at configure time, not module loading time,
103     so fork&configure works as expected.
104 root 1.88 - decreased "seed"-related message priority in Global from 0 (d'oh)
105     to 9, as they are not signifcant.
106 root 1.85 - new experimental module AnyEvent::MP::DataConn to establish
107     additional data connections between nodes.
108 root 1.84 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
109     to call restart.
110 elmex 1.86 - bin/aemp setcert didn't properly handle the filename argument.
111 root 1.90 - removed empty and unused timeout= parameter from protocol greeting.
112 root 1.44
113 root 1.82 1.23 Fri Nov 6 18:46:26 CET 2009
114 root 1.80 - listener-less nodes were misinformed by their masters about
115     the location of new nodes, and therefore didn't connect
116     properly in all cases.
117 root 1.81 - messages send during node-up processing could sometimes get lost,
118     which would hamper global's ability to mesh the network.
119     - fixed AnyEvent::MP::Global::grp_reg to return a guard also
120     in scalar context.
121     - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
122     in scalar context.
123 root 1.79 - try to improve error reporting when automatically loading
124     a function - being unable to load a module will now
125     stop the process and report the error.
126 elmex 1.78
127 root 1.77 1.22 Sat Oct 17 03:41:47 CEST 2009
128     - fix two rcv-bugs: after adding a tagged rcv, the default
129     callback would not be used or changed anymore (reported
130     by Felix Antonius Wilhelm Ostmann, with apologies for
131     taking so long to releae the fix).
132 root 1.76 - added Coro::MP introduction to AnyEvent::MP::Intro.
133 root 1.75 - add peval function.
134    
135 root 1.74 1.21 Mon Oct 5 21:58:36 CEST 2009
136 root 1.72 - always delay kil messages.
137 root 1.74 - remote monitor requests were never cleaned up (found by
138     Sadrak and analysed by elmex).
139     - move $VERSION to AnyEvent::MP and AnyEvent::MP only.
140 root 1.72
141 root 1.71 1.2 Thu Oct 1 22:59:35 CEST 2009
142 root 1.70 - fix a rather big bug where message processing could be
143     inhibited completely.
144 root 1.65 - grp_mon could not return a guard due to a typo.
145 root 1.66 - implement primitive aemp shell.
146 root 1.67 - do not use bound address as listen length (reported by
147     Felix Antonius Wilhelm Ostman).

149 root 1.69 - the mon_guard return value no longer keeps an additional
150     reference to the passed refs.

152 root 1.64 1.1 Fri Sep 11 04:34:03 CEST 2009

154     were too many bugfixes/changes.
155     - new function AnyEvent::MP::cal for simple rpc.
156 root 1.49 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
157 root 1.63 - implemented monitoring for Global groups.
158 root 1.50 - removed all userspace time-outs from the transport, instead
159     rely on tcp retransmit timeouts and tcp keepalive.
160 root 1.48 - spawn now delays spawns on the local node artificially, so
161     it can return before invoking the init function.
162 root 1.55 - break endless recursion between ping-pong ports on the local
163     node after ~50 iterations.
164 root 1.47 - support JSON-encoded aemp arguments.
165 root 1.51 - added aemp restart.
166 root 1.52 - support for starting init functions with parameters added.
167 root 1.53 - data_format, auth_offer and auth_accept are now configurable, albeit
168     not documented.
169 root 1.54 - new service: AnyEvent::MP::LogCatcher.
170 root 1.58 - rely on perl srand'ing better than we could.
171     - try to backport to 5.8.2, unfortunately, recursive dependencies
172     rely on Module::Build, which fails at 5.8.7, so YMMV.
173     - use a vastly different reseeding strategy.
174 root 1.61 - use seed nodes to notify nodes about new nodes.
175 root 1.63 - in the case where a ndoe learns new addresses after it tried
176     connecting, prefer the new addrseses over the old ones.
177 root 1.46
178 root 1.45 1.0 Wed Sep 2 20:40:43 CEST 2009

187     pairs for configuration.
188 root 1.33 - give aemp a full manpage.

193 root 1.31 - nodes get freed when no longer needed.

199 root 1.30
200 root 1.29 0.9 Sat Aug 29 18:47:45 CEST 2009
201     - tutorial was updated to reflect the current API, but
202 root 1.43 does not touch monitoring yet.

204 root 1.25 free-text node identifiers and anonymous nodes.
