21 - INCOMPATIBLE CHANGE: the node protocol used by this version is not
22 compatible to versions <2 - you have to upgrade all nodes.
23 - INCOMPATIBLE CHANGE: many APIs have changed, see the section
24 "PORTING FROM VERSION 1" in the AnyEvent::MP manpage for details.
25 - AnyEvent::MP::Global is now optional - only seed nodes autoload it
26 and create a fully-meshed network with each other, normal nodes only
27 have to connect to seed nodes, other connections are on-demand.
28 - new "norc" and "force" options for MP::configure to ignore
29 or override the rc file.
30 - move seed code to Kernel.
31 - fixed small typo in MP::Transport.
32 - fix (unused) provider-kv (version sometimes missing).
33 - reduce the default export list of MP::Kernel.
34 - reduced various random delays to zero, as they
35 are hopefully no longer needed with the new global
36 protocol.
37 - implement a secure mode that can suppress remote code execution
38 requests on a per-node/per-request basis.
39 - do not use GMP for generating alphanumeric strings even when
40 available, use a more tricky algorithm instead.
41 - anonymous node names and remote port names have been shortened
42 considerably.
43 - 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 - aemp shell no longer leaks one port per command.
48 - nodenames can contain %-escapes such as %n or %u.
49 - aemp now uses aemp/%n/%u as nodename.
50 - known_nodes is gone, it has little value, use all_nodes as
51 replacement.
52 - lots of small change and improvements.
53 - TRACE now shows the portid on SND.
54
55 1.30 Thu Jun 30 11:30:39 CEST 2011
56 - connection errors at the right time would kill node
57 connections in a bad way (patch by Malcolm Studd).
58
59 1.29 Fri May 7 20:13:39 CEST 2010
60 - codename "Sadrak".
61 - fix error in callback at AnyEvent/MP/Global.pm line 339
62 (found by Sadrak).
63 - listener-less nodes had trouble sending keepalive
64 messages on write timeouts (found by Sadrak).
65 - the monitor guard could cause a memleak due
66 to autovivification if a mon was cleared after
67 the port was gone (analysed by Sadrak).
68 - do not overwrite the config file if we couldn't read it
69 for some reason (lesson demonstrated by Sadrak).
70
71 1.28 Thu Apr 1 21:23:54 CEST 2010
72 - accepted connections didn't correctly set up the SRCNODE
73 in some cases, leading to intra-node messages (such as monitoring)
74 to fail silently (great testcase by Sadrak).
75
76 1.27 Sat Mar 20 21:11:16 CET 2010
77 - avoid exceptions in the transport code if the connection
78 fails during TLS negotiation.
79 - delay new address broadcasts in seednodes, to reduce the
80 likelyhood of nodes connecting at the same time, leading to
81 message loss.
82 - improve general message passing efficiency by 8%, and special
83 case json framing for a 50% speed increase.
84 - add hints how to interface to aemp nodes from other programming
85 languages using the aemp protocol in AnyEvent::MP::Transport
86 (it can really be quite simple).
87 - handle unsupported remote framings more gracefully.
88
89 1.26 Wed Dec 30 16:48:37 CET 2009
90 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
91 all nodes need to upgrade.
92 - remote kil's did not work (reported by Eugene Grigoriev).
93 - documented monitor_timeout, connect_interval, auth_offer,
94 auth_accept, framing_format, autocork and nodelay options
95 and make them configurable via bin/aemp.
96 - some doc updates.
97 - remote kil's were not synchronous to message sends which affected
98 nobody, as remote kils were broken.
99 - remote mon/unmonitor requests were not synchronous to message
100 sends either sometimes, although it likely didnt matter.
101
102 1.24 Wed Dec 9 14:59:52 CET 2009
103 - codename "the foul egg".
104 - increased "unmonitored local port died" message level to 2, so
105 it is displayed by default now.
106 - generate random seed at configure time, not module loading time,
107 so fork&configure works as expected.
108 - decreased "seed"-related message priority in Global from 0 (d'oh)
109 to 9, as they are not signifcant.
110 - new experimental module AnyEvent::MP::DataConn to establish
111 additional data connections between nodes.
112 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
113 to call restart.
114 - bin/aemp setcert didn't properly handle the filename argument.
115 - removed empty and unused timeout= parameter from protocol greeting.
116
117 1.23 Fri Nov 6 18:46:26 CET 2009
118 - listener-less nodes were misinformed by their masters about
119 the location of new nodes, and therefore didn't connect
120 properly in all cases.
121 - messages send during node-up processing could sometimes get lost,
122 which would hamper global's ability to mesh the network.
123 - fixed AnyEvent::MP::Global::grp_reg to return a guard also
124 in scalar context.
125 - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
126 in scalar context.
127 - try to improve error reporting when automatically loading
128 a function - being unable to load a module will now
129 stop the process and report the error.
130
131 1.22 Sat Oct 17 03:41:47 CEST 2009
132 - fix two rcv-bugs: after adding a tagged rcv, the default
133 callback would not be used or changed anymore (reported
134 by Felix Antonius Wilhelm Ostmann, with apologies for
135 taking so long to releae the fix).
136 - added Coro::MP introduction to AnyEvent::MP::Intro.
137 - add peval function.
138
139 1.21 Mon Oct 5 21:58:36 CEST 2009
140 - always delay kil messages.
141 - remote monitor requests were never cleaned up (found by
142 Sadrak and analysed by elmex).
143 - move $VERSION to AnyEvent::MP and AnyEvent::MP only.
144
145 1.2 Thu Oct 1 22:59:35 CEST 2009
146 - fix a rather big bug where message processing could be
147 inhibited completely.
148 - grp_mon could not return a guard due to a typo.
149 - implement primitive aemp shell.
150 - do not use bound address as listen length (reported by
151 Felix Antonius Wilhelm Ostman).
152 - no longer export an undefined "reg" function from AE::MP.
153 - the mon_guard return value no longer keeps an additional
154 reference to the passed refs.
155
156 1.1 Fri Sep 11 04:34:03 CEST 2009
157 - bumped the transport protocol to version 1 - sorry, but there
158 were too many bugfixes/changes.
159 - new function AnyEvent::MP::cal for simple rpc.
160 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
161 - implemented monitoring for Global groups.
162 - removed all userspace time-outs from the transport, instead
163 rely on tcp retransmit timeouts and tcp keepalive.
164 - spawn now delays spawns on the local node artificially, so
165 it can return before invoking the init function.
166 - break endless recursion between ping-pong ports on the local
167 node after ~50 iterations.
168 - support JSON-encoded aemp arguments.
169 - added aemp restart.
170 - support for starting init functions with parameters added.
171 - data_format, auth_offer and auth_accept are now configurable, albeit
172 not documented.
173 - new service: AnyEvent::MP::LogCatcher.
174 - rely on perl srand'ing better than we could.
175 - try to backport to 5.8.2, unfortunately, recursive dependencies
176 rely on Module::Build, which fails at 5.8.7, so YMMV.
177 - use a vastly different reseeding strategy.
178 - use seed nodes to notify nodes about new nodes.
179 - in the case where a ndoe learns new addresses after it tried
180 connecting, prefer the new addrseses over the old ones.
181
182 1.0 Wed Sep 2 20:40:43 CEST 2009
183 - randomise more connection times, but reduce delay to 0.2s (seeds)
184 and 0.05s (normal connects).
185 - upgrade to and require AnyEvent::Watchdog 1.0.
186
187 0.95 Mon Aug 31 22:03:55 CEST 2009
188 - tutorial finally covers all the basics, maybe not optimally, but it
189 is covered.
190 - rename initialise_node to configure and accepts key => value
191 pairs for configuration.
192 - give aemp a full manpage.
193 - bin/aemp now expects comma-separated lists and supports multiple
194 subcommands.
195 - new aemp eval subcommand.
196 - new aemp parent subcommand.
197 - nodes get freed when no longer needed.
198 - support "*" hostname to specify all local interface addresses
199 (without localhost etc.).
200 - support "*" port to specify a dynamically-assigned port (which
201 is the default now).
202 - fix per-transport memory leak.
203
204 0.9 Sat Aug 29 18:47:45 CEST 2009
205 - tutorial was updated to reflect the current API, but
206 does not touch monitoring yet.
207 - got rid of noderefs and slave nodes entirely, introduce
208 free-text node identifiers and anonymous nodes.
209 - document security issues with tls_anon method and introduce
210 optional tls_md6_64_256 method.
211
212 0.8 Wed Aug 19 07:54:50 CEST 2009
