24 - INCOMPATIBLE CHANGE: the node protocol used by this version is not
25 compatible to versions <2 - you have to upgrade all nodes.
26 - INCOMPATIBLE CHANGE: many APIs have changed, see the section
27 "PORTING FROM VERSION 1" in the AnyEvent::MP manpage for details.
28 - AnyEvent::MP::Global is now optional - only seed nodes autoload it
29 and create a fully-meshed network with each other, normal nodes only
30 have to connect to seed nodes, other connections are on-demand.
31 - remove md6 auth algorithms (and use algorithms based on SHA3 instead).
32 - implement CBOR framing and make it the preferred format.
33 - new "norc" and "force" options for MP::configure to ignore
34 or override the rc file.
35 - a shitload of minor and major fixes all reported and debugged
36 by Felix Ostmann.
37 - move seed code to Kernel.
38 - non-json receive framing was probably broken.
39 - fixed small typo in MP::Transport.
40 - fix (unused) provider-kv (version sometimes missing).
41 - reduce the default export list of MP::Kernel.
42 - reduced various random delays to zero, as they
43 are hopefully no longer needed with the new global
44 protocol.
45 - implement a secure mode that can suppress (some) code execution
46 requests.
47 - do not use GMP for generating alphanumeric strings even when
48 available, use a more tricky algorithm instead.
49 - anonymous node names and remote port names have been shortened
50 considerably.
51 - $AnyEvent::MP::Kernel::SRCNODE contains the node ID of the origin
52 node during message receives.
53 - aemp shell now supports "package" selection and offers an
54 $ECHO port you can send messages to.
55 - rely on perl rand() instead of using /dev/urandom when available, as
56 hopefully it is random enough.
57 - aemp shell no longer leaks one port per command.
58 - nodenames can contain %-escapes such as %n or %u.
59 - aemp now uses aemp/%n/%u as nodename.
60 - configure supports "eval", a small perl snippet to initialsie a node,
61 most useful in "aemp run eval ...".
62 - known_nodes is gone, it has little value, use all_nodes as
63 replacement.
64 - lots of small change and improvements.
65 - node_is_known has been removed.
66 - TRACE now shows the portid on SND.
67 - aggressively reduce number of external modules, to reduce
68 memory usage for nodes.
69 - rework most of the documentation.
70 - clean up MP::Kernel exports.
71
72 1.30 Thu Jun 30 11:30:39 CEST 2011
73 - connection errors at the right time would kill node
74 connections in a bad way (patch by Malcolm Studd).
75
76 1.29 Fri May 7 20:13:39 CEST 2010
77 - codename "Sadrak".
78 - fix error in callback at AnyEvent/MP/Global.pm line 339
79 (found by Sadrak).
80 - listener-less nodes had trouble sending keepalive
81 messages on write timeouts (found by Sadrak).
82 - the monitor guard could cause a memleak due
83 to autovivification if a mon was cleared after
84 the port was gone (analysed by Sadrak).
85 - do not overwrite the config file if we couldn't read it
86 for some reason (lesson demonstrated by Sadrak).
87
88 1.28 Thu Apr 1 21:23:54 CEST 2010
89 - accepted connections didn't correctly set up the SRCNODE
90 in some cases, leading to intra-node messages (such as monitoring)
91 to fail silently (great testcase by Sadrak).
92
93 1.27 Sat Mar 20 21:11:16 CET 2010
94 - avoid exceptions in the transport code if the connection
95 fails during TLS negotiation.
96 - delay new address broadcasts in seednodes, to reduce the
97 likelyhood of nodes connecting at the same time, leading to
98 message loss.
99 - improve general message passing efficiency by 8%, and special
100 case json framing for a 50% speed increase.
101 - add hints how to interface to aemp nodes from other programming
102 languages using the aemp protocol in AnyEvent::MP::Transport
103 (it can really be quite simple).
104 - handle unsupported remote framings more gracefully.
105
106 1.26 Wed Dec 30 16:48:37 CET 2009
107 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
108 all nodes need to upgrade.
109 - remote kil's did not work (reported by Eugene Grigoriev).
110 - documented monitor_timeout, connect_interval, auth_offer,
111 auth_accept, framing_format, autocork and nodelay options
112 and make them configurable via bin/aemp.
113 - some doc updates.
114 - remote kil's were not synchronous to message sends which affected
115 nobody, as remote kils were broken.
116 - remote mon/unmonitor requests were not synchronous to message
117 sends either sometimes, although it likely didnt matter.
118
119 1.24 Wed Dec 9 14:59:52 CET 2009
120 - codename "the foul egg".
121 - increased "unmonitored local port died" message level to 2, so
122 it is displayed by default now.
123 - generate random seed at configure time, not module loading time,
124 so fork&configure works as expected.
125 - decreased "seed"-related message priority in Global from 0 (d'oh)
126 to 9, as they are not signifcant.
127 - new experimental module AnyEvent::MP::DataConn to establish
128 additional data connections between nodes.
129 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
130 to call restart.
131 - bin/aemp setcert didn't properly handle the filename argument.
132 - removed empty and unused timeout= parameter from protocol greeting.
133
134 1.23 Fri Nov 6 18:46:26 CET 2009
135 - listener-less nodes were misinformed by their masters about
136 the location of new nodes, and therefore didn't connect
137 properly in all cases.
138 - messages send during node-up processing could sometimes get lost,
139 which would hamper global's ability to mesh the network.
140 - fixed AnyEvent::MP::Global::grp_reg to return a guard also
141 in scalar context.
142 - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
143 in scalar context.
144 - try to improve error reporting when automatically loading
145 a function - being unable to load a module will now
146 stop the process and report the error.
147
148 1.22 Sat Oct 17 03:41:47 CEST 2009
149 - fix two rcv-bugs: after adding a tagged rcv, the default
150 callback would not be used or changed anymore (reported
151 by Felix Antonius Wilhelm Ostmann, with apologies for
152 taking so long to releae the fix).
153 - added Coro::MP introduction to AnyEvent::MP::Intro.
154 - add peval function.
155
156 1.21 Mon Oct 5 21:58:36 CEST 2009
157 - always delay kil messages.
158 - remote monitor requests were never cleaned up (found by
159 Sadrak and analysed by elmex).
160 - move $VERSION to AnyEvent::MP and AnyEvent::MP only.
161
162 1.2 Thu Oct 1 22:59:35 CEST 2009
163 - fix a rather big bug where message processing could be
164 inhibited completely.
165 - grp_mon could not return a guard due to a typo.
166 - implement primitive aemp shell.
167 - do not use bound address as listen length (reported by
168 Felix Antonius Wilhelm Ostman).
169 - no longer export an undefined "reg" function from AE::MP.
170 - the mon_guard return value no longer keeps an additional
171 reference to the passed refs.
172
173 1.1 Fri Sep 11 04:34:03 CEST 2009
174 - bumped the transport protocol to version 1 - sorry, but there
175 were too many bugfixes/changes.
176 - new function AnyEvent::MP::cal for simple rpc.
177 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
178 - implemented monitoring for Global groups.
179 - removed all userspace time-outs from the transport, instead
180 rely on tcp retransmit timeouts and tcp keepalive.
181 - spawn now delays spawns on the local node artificially, so
182 it can return before invoking the init function.
183 - break endless recursion between ping-pong ports on the local
184 node after ~50 iterations.
185 - support JSON-encoded aemp arguments.
186 - added aemp restart.
187 - support for starting init functions with parameters added.
188 - data_format, auth_offer and auth_accept are now configurable, albeit
189 not documented.
190 - new service: AnyEvent::MP::LogCatcher.
191 - rely on perl srand'ing better than we could.
192 - try to backport to 5.8.2, unfortunately, recursive dependencies
193 rely on Module::Build, which fails at 5.8.7, so YMMV.
194 - use a vastly different reseeding strategy.
195 - use seed nodes to notify nodes about new nodes.
196 - in the case where a ndoe learns new addresses after it tried
197 connecting, prefer the new addrseses over the old ones.
198
199 1.0 Wed Sep 2 20:40:43 CEST 2009
200 - randomise more connection times, but reduce delay to 0.2s (seeds)
201 and 0.05s (normal connects).
202 - upgrade to and require AnyEvent::Watchdog 1.0.
203
204 0.95 Mon Aug 31 22:03:55 CEST 2009
205 - tutorial finally covers all the basics, maybe not optimally, but it
206 is covered.
207 - rename initialise_node to configure and accepts key => value
208 pairs for configuration.
209 - give aemp a full manpage.
210 - bin/aemp now expects comma-separated lists and supports multiple
211 subcommands.
212 - new aemp eval subcommand.
213 - new aemp parent subcommand.
214 - nodes get freed when no longer needed.
215 - support "*" hostname to specify all local interface addresses
216 (without localhost etc.).
217 - support "*" port to specify a dynamically-assigned port (which
218 is the default now).
219 - fix per-transport memory leak.
220
221 0.9 Sat Aug 29 18:47:45 CEST 2009
222 - tutorial was updated to reflect the current API, but
223 does not touch monitoring yet.
224 - got rid of noderefs and slave nodes entirely, introduce
225 free-text node identifiers and anonymous nodes.
226 - document security issues with tls_anon method and introduce
227 optional tls_md6_64_256 method.
228
229 0.8 Wed Aug 19 07:54:50 CEST 2009
