26 root 1.118 2
27     - INCOMPATIBLE CHANGE: the node protocol used by this version is not
28 root 1.121 compatible to versions <2 - you have to upgrade all nodes.
29 root 1.124 - INCOMPATIBLE CHANGE: many APIs have changed, see the section
30     "PORTING FROM VERSION 1" in the AnyEvent::MP manpage for details.
31 root 1.121 - AnyEvent::MP::Global is now optional - only seed nodes autoload it
32     and create a fully-meshed network with each other, normal nodes only
33     have to connect to seed nodes, other connections are on-demand.
34 root 1.118 - new "norc" and "force" options for MP::configure to ignore
35     or override the rc file.
36 root 1.151 - a shitload of minor and major fixes all reported and debugged
37     by Felix Ostmann.
38 root 1.116 - move seed code to Kernel.
39 root 1.136 - non-json receive framing was probably broken.
40 root 1.118 - fixed small typo in MP::Transport.
41     - fix (unused) provider-kv (version sometimes missing).
42     - reduce the default export list of MP::Kernel.
43 root 1.120 - reduced various random delays to zero, as they
44     are hopefully no longer needed with the new global
45     protocol.
46 root 1.148 - implement a secure mode that can suppress (some) code execution
47     requests.
48 root 1.122 - do not use GMP for generating alphanumeric strings even when
49     available, use a more tricky algorithm instead.
50 root 1.121 - anonymous node names and remote port names have been shortened
51     considerably.
52 root 1.136 - $AnyEvent::MP::Kernel::SRCNODE contains the node ID of the origin
53     node during message receives.
54 root 1.122 - aemp shell now supports "package" selection and offers an
55 root 1.138 $ECHO port you can send messages to.
56 root 1.122 - rely on perl rand() instead of using /dev/urandom when available, as
57     hopefully it is random enough.
58 root 1.123 - aemp shell no longer leaks one port per command.
59 root 1.125 - nodenames can contain %-escapes such as %n or %u.
60     - aemp now uses aemp/%n/%u as nodename.
61 root 1.143 - configure supports "eval", a small perl snippet to initialsie a node,
62     most useful in "aemp run eval ...".
63 root 1.124 - known_nodes is gone, it has little value, use all_nodes as
64     replacement.
65 root 1.125 - lots of small change and improvements.
66 root 1.134 - node_is_known has been removed.
67 root 1.129 - TRACE now shows the portid on SND.
68 root 1.145 - aggressively reduce number of external modules, to reduce
69     memory usage for nodes.
70 root 1.146 - rework most of the documentation.
71     - clean up MP::Kernel exports.
72 elmex 1.115
73 root 1.114 1.30 Thu Jun 30 11:30:39 CEST 2011
74     - connection errors at the right time would kill node
75     connections in a bad way (patch by Malcolm Studd).
76 root 1.107
77 root 1.113 1.29 Fri May 7 20:13:39 CEST 2010
78     - codename "Sadrak".
79 root 1.111 - fix error in callback at AnyEvent/MP/Global.pm line 339
80     (found by Sadrak).
81 root 1.108 - listener-less nodes had trouble sending keepalive
82 root 1.109 messages on write timeouts (found by Sadrak).
83     - the monitor guard could cause a memleak due
84     to autovivification if a mon was cleared after
85     the port was gone (analysed by Sadrak).
86 root 1.112 - do not overwrite the config file if we couldn't read it
87     for some reason (lesson demonstrated by Sadrak).
88 root 1.108
89 root 1.106 1.28 Thu Apr 1 21:23:54 CEST 2010
90 root 1.111 - accepted connections didn't correctly set up the SRCNODE
91 root 1.106 in some cases, leading to intra-node messages (such as monitoring)
92     to fail silently (great testcase by Sadrak).
93    
94 root 1.105 1.27 Sat Mar 20 21:11:16 CET 2010
95 root 1.101 - avoid exceptions in the transport code if the connection
96     fails during TLS negotiation.
97 root 1.102 - delay new address broadcasts in seednodes, to reduce the
98 root 1.103 likelyhood of nodes connecting at the same time, leading to
99 root 1.102 message loss.
100 root 1.104 - improve general message passing efficiency by 8%, and special
101     case json framing for a 50% speed increase.
102 root 1.99 - add hints how to interface to aemp nodes from other programming
103     languages using the aemp protocol in AnyEvent::MP::Transport
104     (it can really be quite simple).
105 root 1.100 - handle unsupported remote framings more gracefully.
106 root 1.99
107 root 1.98 1.26 Wed Dec 30 16:48:37 CET 2009
108 root 1.94 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
109     all nodes need to upgrade.
110 root 1.93 - remote kil's did not work (reported by Eugene Grigoriev).
111 root 1.94 - documented monitor_timeout, connect_interval, auth_offer,
112     auth_accept, framing_format, autocork and nodelay options
113     and make them configurable via bin/aemp.
114 root 1.96 - some doc updates.
115     - remote kil's were not synchronous to message sends which affected
116     nobody, as remote kils were broken.
117 root 1.97 - remote mon/unmonitor requests were not synchronous to message
118     sends either sometimes, although it likely didnt matter.
119 root 1.92
120 root 1.91 1.24 Wed Dec 9 14:59:52 CET 2009
121 root 1.87 - codename "the foul egg".
122     - increased "unmonitored local port died" message level to 2, so
123     it is displayed by default now.
124 root 1.89 - generate random seed at configure time, not module loading time,
125     so fork&configure works as expected.
126 root 1.88 - decreased "seed"-related message priority in Global from 0 (d'oh)
127     to 9, as they are not signifcant.
128 root 1.85 - new experimental module AnyEvent::MP::DataConn to establish
129     additional data connections between nodes.
130 root 1.84 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
131     to call restart.
132 elmex 1.86 - bin/aemp setcert didn't properly handle the filename argument.
133 root 1.90 - removed empty and unused timeout= parameter from protocol greeting.
134 root 1.44
135 root 1.82 1.23 Fri Nov 6 18:46:26 CET 2009
136 root 1.80 - listener-less nodes were misinformed by their masters about
137     the location of new nodes, and therefore didn't connect
138     properly in all cases.
139 root 1.81 - messages send during node-up processing could sometimes get lost,
140     which would hamper global's ability to mesh the network.
141     - fixed AnyEvent::MP::Global::grp_reg to return a guard also
142     in scalar context.
143     - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
144     in scalar context.
145 root 1.79 - try to improve error reporting when automatically loading
146     a function - being unable to load a module will now
147     stop the process and report the error.
148 elmex 1.78
149 root 1.77 1.22 Sat Oct 17 03:41:47 CEST 2009
150     - fix two rcv-bugs: after adding a tagged rcv, the default
151     callback would not be used or changed anymore (reported
152     by Felix Antonius Wilhelm Ostmann, with apologies for
153     taking so long to releae the fix).
154 root 1.76 - added Coro::MP introduction to AnyEvent::MP::Intro.
155 root 1.75 - add peval function.
156

158 root 1.72 - always delay kil messages.
159 root 1.74 - remote monitor requests were never cleaned up (found by
160     Sadrak and analysed by elmex).
161     - move $VERSION to AnyEvent::MP and AnyEvent::MP only.
162 root 1.72
163 root 1.71 1.2 Thu Oct 1 22:59:35 CEST 2009
164 root 1.70 - fix a rather big bug where message processing could be
165     inhibited completely.
166 root 1.65 - grp_mon could not return a guard due to a typo.
167 root 1.66 - implement primitive aemp shell.
168 root 1.67 - do not use bound address as listen length (reported by
169     Felix Antonius Wilhelm Ostman).

176     were too many bugfixes/changes.
177     - new function AnyEvent::MP::cal for simple rpc.
178 root 1.49 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
179 root 1.63 - implemented monitoring for Global groups.

181     rely on tcp retransmit timeouts and tcp keepalive.
182 root 1.48 - spawn now delays spawns on the local node artificially, so
183     it can return before invoking the init function.
184 root 1.55 - break endless recursion between ping-pong ports on the local
185     node after ~50 iterations.
186 root 1.47 - support JSON-encoded aemp arguments.

192 root 1.58 - rely on perl srand'ing better than we could.
193     - try to backport to 5.8.2, unfortunately, recursive dependencies
194     rely on Module::Build, which fails at 5.8.7, so YMMV.
195     - use a vastly different reseeding strategy.
196 root 1.61 - use seed nodes to notify nodes about new nodes.
197 root 1.63 - in the case where a ndoe learns new addresses after it tried
198     connecting, prefer the new addrseses over the old ones.
199 root 1.46
200 root 1.45 1.0 Wed Sep 2 20:40:43 CEST 2009

209     pairs for configuration.
210 root 1.33 - give aemp a full manpage.

222 root 1.29 0.9 Sat Aug 29 18:47:45 CEST 2009
223     - tutorial was updated to reflect the current API, but
224 root 1.43 does not touch monitoring yet.
