25
26 2.02 Sun Jul 29 04:22:53 CEST 2018
27 - hardcode version in MP.pm to help the CPAN indexer.
28
29 2.01 Tue Jul 24 09:02:34 CEST 2018
30 - try to work around a race condition that we can't identify
31 (patch suggested by Sadrak).
32
33 2.0 Tue Jul 24 08:52:26 CEST 2018
34 - INCOMPATIBLE CHANGE: the node protocol used by this version is not
35 compatible to versions <2 - you have to upgrade all nodes.
36 - INCOMPATIBLE CHANGE: many APIs have changed, see the section
37 "PORTING FROM VERSION 1" in the AnyEvent::MP manpage for details.
38 - AnyEvent::MP::Global is now optional - only seed nodes autoload it
39 and create a fully-meshed network with each other, normal nodes only
40 have to connect to seed nodes, other connections are on-demand.
41 - remove md6 auth algorithms (and use algorithms based on SHA3 instead).
42 - implement CBOR framing and make it the preferred format.
43 - new "norc" and "force" options for MP::configure to ignore
44 or override the rc file.
45 - a shitload of minor and major fixes all reported and debugged
46 by Felix Ostmann.
47 - move seed code to Kernel.
48 - non-json receive framing was probably broken.
49 - fixed small typo in MP::Transport.
50 - fix (unused) provider-kv (version sometimes missing).
51 - reduce the default export list of MP::Kernel.
52 - reduced various random delays to zero, as they
53 are hopefully no longer needed with the new global
54 protocol.
55 - implement a secure mode that can suppress (some) code execution
56 requests.
57 - do not use GMP for generating alphanumeric strings even when
58 available, use a more tricky algorithm instead.
59 - anonymous node names and remote port names have been shortened
60 considerably.
61 - $AnyEvent::MP::Kernel::SRCNODE contains the node ID of the origin
62 node during message receives.
63 - aemp shell now supports "package" selection and offers an
64 $ECHO port you can send messages to.
65 - rely on perl rand() instead of using /dev/urandom when available, as
66 hopefully it is random enough.
67 - aemp shell no longer leaks one port per command.
68 - nodenames can contain %-escapes such as %n or %u.
69 - aemp now uses aemp/%n/%u as nodename.
70 - configure supports "eval", a small perl snippet to initialsie a node,
71 most useful in "aemp run eval ...".
72 - known_nodes is gone, it has little value, use all_nodes as
73 replacement.
74 - lots of small change and improvements.
75 - node_is_known has been removed.
76 - TRACE now shows the portid on SND.
77 - aggressively reduce number of external modules, to reduce
78 memory usage for nodes.
79 - rework most of the documentation.
80 - clean up MP::Kernel exports.
81 - include AnyEvent::MP in AnyEvent::MP::Kernel's @CARP_NOT to
82 hopefully improve error messages.
83
84 1.30 Thu Jun 30 11:30:39 CEST 2011
85 - connection errors at the right time would kill node
86 connections in a bad way (patch by Malcolm Studd).
87
88 1.29 Fri May 7 20:13:39 CEST 2010
89 - codename "Sadrak".
90 - fix error in callback at AnyEvent/MP/Global.pm line 339
91 (found by Sadrak).
92 - listener-less nodes had trouble sending keepalive
93 messages on write timeouts (found by Sadrak).
94 - the monitor guard could cause a memleak due
95 to autovivification if a mon was cleared after
96 the port was gone (analysed by Sadrak).
97 - do not overwrite the config file if we couldn't read it
98 for some reason (lesson demonstrated by Sadrak).
99
100 1.28 Thu Apr 1 21:23:54 CEST 2010
101 - accepted connections didn't correctly set up the SRCNODE
102 in some cases, leading to intra-node messages (such as monitoring)
103 to fail silently (great testcase by Sadrak).
104
105 1.27 Sat Mar 20 21:11:16 CET 2010
106 - avoid exceptions in the transport code if the connection
107 fails during TLS negotiation.
108 - delay new address broadcasts in seednodes, to reduce the
109 likelyhood of nodes connecting at the same time, leading to
110 message loss.
111 - improve general message passing efficiency by 8%, and special
112 case json framing for a 50% speed increase.
113 - add hints how to interface to aemp nodes from other programming
114 languages using the aemp protocol in AnyEvent::MP::Transport
115 (it can really be quite simple).
116 - handle unsupported remote framings more gracefully.
117
118 1.26 Wed Dec 30 16:48:37 CET 2009
119 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
120 all nodes need to upgrade.
121 - remote kil's did not work (reported by Eugene Grigoriev).
122 - documented monitor_timeout, connect_interval, auth_offer,
123 auth_accept, framing_format, autocork and nodelay options
124 and make them configurable via bin/aemp.
125 - some doc updates.
126 - remote kil's were not synchronous to message sends which affected
127 nobody, as remote kils were broken.
128 - remote mon/unmonitor requests were not synchronous to message
129 sends either sometimes, although it likely didnt matter.
130
131 1.24 Wed Dec 9 14:59:52 CET 2009
132 - codename "the foul egg".
133 - increased "unmonitored local port died" message level to 2, so
134 it is displayed by default now.
135 - generate random seed at configure time, not module loading time,
136 so fork&configure works as expected.
137 - decreased "seed"-related message priority in Global from 0 (d'oh)
138 to 9, as they are not signifcant.
139 - new experimental module AnyEvent::MP::DataConn to establish
140 additional data connections between nodes.
141 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
142 to call restart.
143 - bin/aemp setcert didn't properly handle the filename argument.
144 - removed empty and unused timeout= parameter from protocol greeting.
145
146 1.23 Fri Nov 6 18:46:26 CET 2009
147 - listener-less nodes were misinformed by their masters about
148 the location of new nodes, and therefore didn't connect
149 properly in all cases.
150 - messages send during node-up processing could sometimes get lost,
151 which would hamper global's ability to mesh the network.
152 - fixed AnyEvent::MP::Global::grp_reg to return a guard also
153 in scalar context.
154 - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
155 in scalar context.
156 - try to improve error reporting when automatically loading
157 a function - being unable to load a module will now
158 stop the process and report the error.
159
160 1.22 Sat Oct 17 03:41:47 CEST 2009
161 - fix two rcv-bugs: after adding a tagged rcv, the default
162 callback would not be used or changed anymore (reported
163 by Felix Antonius Wilhelm Ostmann, with apologies for
164 taking so long to releae the fix).
165 - added Coro::MP introduction to AnyEvent::MP::Intro.
166 - add peval function.
167
168 1.21 Mon Oct 5 21:58:36 CEST 2009
169 - always delay kil messages.
170 - remote monitor requests were never cleaned up (found by
171 Sadrak and analysed by elmex).
172 - move $VERSION to AnyEvent::MP and AnyEvent::MP only.
173
174 1.2 Thu Oct 1 22:59:35 CEST 2009
175 - fix a rather big bug where message processing could be
176 inhibited completely.
177 - grp_mon could not return a guard due to a typo.
178 - implement primitive aemp shell.
179 - do not use bound address as listen length (reported by
180 Felix Antonius Wilhelm Ostman).
181 - no longer export an undefined "reg" function from AE::MP.
182 - the mon_guard return value no longer keeps an additional
183 reference to the passed refs.
184
185 1.1 Fri Sep 11 04:34:03 CEST 2009
186 - bumped the transport protocol to version 1 - sorry, but there
187 were too many bugfixes/changes.
188 - new function AnyEvent::MP::cal for simple rpc.
189 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
190 - implemented monitoring for Global groups.
191 - removed all userspace time-outs from the transport, instead
192 rely on tcp retransmit timeouts and tcp keepalive.
193 - spawn now delays spawns on the local node artificially, so
194 it can return before invoking the init function.
195 - break endless recursion between ping-pong ports on the local
196 node after ~50 iterations.
197 - support JSON-encoded aemp arguments.
198 - added aemp restart.
199 - support for starting init functions with parameters added.
200 - data_format, auth_offer and auth_accept are now configurable, albeit
201 not documented.
202 - new service: AnyEvent::MP::LogCatcher.
203 - rely on perl srand'ing better than we could.
204 - try to backport to 5.8.2, unfortunately, recursive dependencies
205 rely on Module::Build, which fails at 5.8.7, so YMMV.
206 - use a vastly different reseeding strategy.
207 - use seed nodes to notify nodes about new nodes.
208 - in the case where a ndoe learns new addresses after it tried
209 connecting, prefer the new addrseses over the old ones.
210
211 1.0 Wed Sep 2 20:40:43 CEST 2009
212 - randomise more connection times, but reduce delay to 0.2s (seeds)
213 and 0.05s (normal connects).
214 - upgrade to and require AnyEvent::Watchdog 1.0.
215
216 0.95 Mon Aug 31 22:03:55 CEST 2009
217 - tutorial finally covers all the basics, maybe not optimally, but it
218 is covered.
219 - rename initialise_node to configure and accepts key => value
220 pairs for configuration.
221 - give aemp a full manpage.
222 - bin/aemp now expects comma-separated lists and supports multiple
223 subcommands.
224 - new aemp eval subcommand.
225 - new aemp parent subcommand.
226 - nodes get freed when no longer needed.
227 - support "*" hostname to specify all local interface addresses
228 (without localhost etc.).
229 - support "*" port to specify a dynamically-assigned port (which
230 is the default now).
231 - fix per-transport memory leak.
232
233 0.9 Sat Aug 29 18:47:45 CEST 2009
234 - tutorial was updated to reflect the current API, but
235 does not touch monitoring yet.
236 - got rid of noderefs and slave nodes entirely, introduce
237 free-text node identifiers and anonymous nodes.
238 - document security issues with tls_anon method and introduce
239 optional tls_md6_64_256 method.
240
241 0.8 Wed Aug 19 07:54:50 CEST 2009
