23 2.01 Tue Jul 24 09:02:34 CEST 2018
24 - try to work around a race condition that we can't identify
25 (patch suggested by Sadrak).
26
27 2.0 Tue Jul 24 08:52:26 CEST 2018
28 - INCOMPATIBLE CHANGE: the node protocol used by this version is not
29 compatible to versions <2 - you have to upgrade all nodes.
30 - INCOMPATIBLE CHANGE: many APIs have changed, see the section
31 "PORTING FROM VERSION 1" in the AnyEvent::MP manpage for details.
32 - AnyEvent::MP::Global is now optional - only seed nodes autoload it
33 and create a fully-meshed network with each other, normal nodes only
34 have to connect to seed nodes, other connections are on-demand.
35 - remove md6 auth algorithms (and use algorithms based on SHA3 instead).
36 - implement CBOR framing and make it the preferred format.
37 - new "norc" and "force" options for MP::configure to ignore
38 or override the rc file.
39 - a shitload of minor and major fixes all reported and debugged
40 by Felix Ostmann.
41 - move seed code to Kernel.
42 - non-json receive framing was probably broken.
43 - fixed small typo in MP::Transport.
44 - fix (unused) provider-kv (version sometimes missing).
45 - reduce the default export list of MP::Kernel.
46 - reduced various random delays to zero, as they
47 are hopefully no longer needed with the new global
48 protocol.
49 - implement a secure mode that can suppress (some) code execution
50 requests.
51 - do not use GMP for generating alphanumeric strings even when
52 available, use a more tricky algorithm instead.
53 - anonymous node names and remote port names have been shortened
54 considerably.
55 - $AnyEvent::MP::Kernel::SRCNODE contains the node ID of the origin
56 node during message receives.
57 - aemp shell now supports "package" selection and offers an
58 $ECHO port you can send messages to.
59 - rely on perl rand() instead of using /dev/urandom when available, as
60 hopefully it is random enough.
61 - aemp shell no longer leaks one port per command.
62 - nodenames can contain %-escapes such as %n or %u.
63 - aemp now uses aemp/%n/%u as nodename.
64 - configure supports "eval", a small perl snippet to initialsie a node,
65 most useful in "aemp run eval ...".
66 - known_nodes is gone, it has little value, use all_nodes as
67 replacement.
68 - lots of small change and improvements.
69 - node_is_known has been removed.
70 - TRACE now shows the portid on SND.
71 - aggressively reduce number of external modules, to reduce
72 memory usage for nodes.
73 - rework most of the documentation.
74 - clean up MP::Kernel exports.
75 - include AnyEvent::MP in AnyEvent::MP::Kernel's @CARP_NOT to
76 hopefully improve error messages.
77
78 1.30 Thu Jun 30 11:30:39 CEST 2011
79 - connection errors at the right time would kill node
80 connections in a bad way (patch by Malcolm Studd).
81
82 1.29 Fri May 7 20:13:39 CEST 2010
83 - codename "Sadrak".
84 - fix error in callback at AnyEvent/MP/Global.pm line 339
85 (found by Sadrak).
86 - listener-less nodes had trouble sending keepalive
87 messages on write timeouts (found by Sadrak).
88 - the monitor guard could cause a memleak due
89 to autovivification if a mon was cleared after
90 the port was gone (analysed by Sadrak).
91 - do not overwrite the config file if we couldn't read it
92 for some reason (lesson demonstrated by Sadrak).
93
94 1.28 Thu Apr 1 21:23:54 CEST 2010
95 - accepted connections didn't correctly set up the SRCNODE
96 in some cases, leading to intra-node messages (such as monitoring)
97 to fail silently (great testcase by Sadrak).
98
99 1.27 Sat Mar 20 21:11:16 CET 2010
100 - avoid exceptions in the transport code if the connection
101 fails during TLS negotiation.
102 - delay new address broadcasts in seednodes, to reduce the
103 likelyhood of nodes connecting at the same time, leading to
104 message loss.
105 - improve general message passing efficiency by 8%, and special
106 case json framing for a 50% speed increase.
107 - add hints how to interface to aemp nodes from other programming
108 languages using the aemp protocol in AnyEvent::MP::Transport
109 (it can really be quite simple).
110 - handle unsupported remote framings more gracefully.
111
112 1.26 Wed Dec 30 16:48:37 CET 2009
113 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
114 all nodes need to upgrade.
115 - remote kil's did not work (reported by Eugene Grigoriev).
116 - documented monitor_timeout, connect_interval, auth_offer,
117 auth_accept, framing_format, autocork and nodelay options
118 and make them configurable via bin/aemp.
119 - some doc updates.
120 - remote kil's were not synchronous to message sends which affected
121 nobody, as remote kils were broken.
122 - remote mon/unmonitor requests were not synchronous to message
123 sends either sometimes, although it likely didnt matter.
124
125 1.24 Wed Dec 9 14:59:52 CET 2009
126 - codename "the foul egg".
127 - increased "unmonitored local port died" message level to 2, so
128 it is displayed by default now.
129 - generate random seed at configure time, not module loading time,
130 so fork&configure works as expected.
131 - decreased "seed"-related message priority in Global from 0 (d'oh)
132 to 9, as they are not signifcant.
133 - new experimental module AnyEvent::MP::DataConn to establish
134 additional data connections between nodes.
135 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
136 to call restart.
137 - bin/aemp setcert didn't properly handle the filename argument.
138 - removed empty and unused timeout= parameter from protocol greeting.
139
140 1.23 Fri Nov 6 18:46:26 CET 2009
141 - listener-less nodes were misinformed by their masters about
142 the location of new nodes, and therefore didn't connect
143 properly in all cases.
144 - messages send during node-up processing could sometimes get lost,
145 which would hamper global's ability to mesh the network.
146 - fixed AnyEvent::MP::Global::grp_reg to return a guard also
147 in scalar context.
148 - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
149 in scalar context.
150 - try to improve error reporting when automatically loading
151 a function - being unable to load a module will now
152 stop the process and report the error.
153
154 1.22 Sat Oct 17 03:41:47 CEST 2009
155 - fix two rcv-bugs: after adding a tagged rcv, the default
156 callback would not be used or changed anymore (reported
157 by Felix Antonius Wilhelm Ostmann, with apologies for
158 taking so long to releae the fix).
159 - added Coro::MP introduction to AnyEvent::MP::Intro.
160 - add peval function.
161
162 1.21 Mon Oct 5 21:58:36 CEST 2009
163 - always delay kil messages.
164 - remote monitor requests were never cleaned up (found by
165 Sadrak and analysed by elmex).
166 - move $VERSION to AnyEvent::MP and AnyEvent::MP only.
167
168 1.2 Thu Oct 1 22:59:35 CEST 2009
169 - fix a rather big bug where message processing could be
170 inhibited completely.
171 - grp_mon could not return a guard due to a typo.
172 - implement primitive aemp shell.
173 - do not use bound address as listen length (reported by
174 Felix Antonius Wilhelm Ostman).
175 - no longer export an undefined "reg" function from AE::MP.
176 - the mon_guard return value no longer keeps an additional
177 reference to the passed refs.
178
179 1.1 Fri Sep 11 04:34:03 CEST 2009
180 - bumped the transport protocol to version 1 - sorry, but there
181 were too many bugfixes/changes.
182 - new function AnyEvent::MP::cal for simple rpc.
183 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
184 - implemented monitoring for Global groups.
185 - removed all userspace time-outs from the transport, instead
186 rely on tcp retransmit timeouts and tcp keepalive.
187 - spawn now delays spawns on the local node artificially, so
188 it can return before invoking the init function.
189 - break endless recursion between ping-pong ports on the local
190 node after ~50 iterations.
191 - support JSON-encoded aemp arguments.
192 - added aemp restart.
193 - support for starting init functions with parameters added.
194 - data_format, auth_offer and auth_accept are now configurable, albeit
195 not documented.
196 - new service: AnyEvent::MP::LogCatcher.
197 - rely on perl srand'ing better than we could.
198 - try to backport to 5.8.2, unfortunately, recursive dependencies
199 rely on Module::Build, which fails at 5.8.7, so YMMV.
200 - use a vastly different reseeding strategy.
201 - use seed nodes to notify nodes about new nodes.
202 - in the case where a ndoe learns new addresses after it tried
203 connecting, prefer the new addrseses over the old ones.
204
205 1.0 Wed Sep 2 20:40:43 CEST 2009
206 - randomise more connection times, but reduce delay to 0.2s (seeds)
207 and 0.05s (normal connects).
208 - upgrade to and require AnyEvent::Watchdog 1.0.
209
210 0.95 Mon Aug 31 22:03:55 CEST 2009
211 - tutorial finally covers all the basics, maybe not optimally, but it
212 is covered.
213 - rename initialise_node to configure and accepts key => value
214 pairs for configuration.
215 - give aemp a full manpage.
216 - bin/aemp now expects comma-separated lists and supports multiple
217 subcommands.
218 - new aemp eval subcommand.
219 - new aemp parent subcommand.
220 - nodes get freed when no longer needed.
221 - support "*" hostname to specify all local interface addresses
222 (without localhost etc.).
223 - support "*" port to specify a dynamically-assigned port (which
224 is the default now).
225 - fix per-transport memory leak.
226
227 0.9 Sat Aug 29 18:47:45 CEST 2009
228 - tutorial was updated to reflect the current API, but
229 does not touch monitoring yet.
230 - got rid of noderefs and slave nodes entirely, introduce
231 free-text node identifiers and anonymous nodes.
232 - document security issues with tls_anon method and introduce
233 optional tls_md6_64_256 method.
234
235 0.8 Wed Aug 19 07:54:50 CEST 2009
