26 root 1.161 2.02 Sun Jul 29 04:22:53 CEST 2018
27     - hardcode version in MP.pm to help the CPAN indexer.
28 root 1.154
29 root 1.160 2.01 Tue Jul 24 09:02:34 CEST 2018
30     - try to work around a race condition that we can't identify

32    
33 root 1.159 2.0 Tue Jul 24 08:52:26 CEST 2018
34 root 1.118 - INCOMPATIBLE CHANGE: the node protocol used by this version is not
35 root 1.121 compatible to versions <2 - you have to upgrade all nodes.
36 root 1.124 - INCOMPATIBLE CHANGE: many APIs have changed, see the section
37     "PORTING FROM VERSION 1" in the AnyEvent::MP manpage for details.
38 root 1.121 - 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 root 1.157 - remove md6 auth algorithms (and use algorithms based on SHA3 instead).
42     - implement CBOR framing and make it the preferred format.
43 root 1.118 - new "norc" and "force" options for MP::configure to ignore
44     or override the rc file.
45 root 1.151 - a shitload of minor and major fixes all reported and debugged
46     by Felix Ostmann.
47 root 1.116 - move seed code to Kernel.
48 root 1.136 - non-json receive framing was probably broken.
49 root 1.118 - fixed small typo in MP::Transport.
50     - fix (unused) provider-kv (version sometimes missing).
51     - reduce the default export list of MP::Kernel.
52 root 1.120 - reduced various random delays to zero, as they
53     are hopefully no longer needed with the new global
54     protocol.
55 root 1.148 - implement a secure mode that can suppress (some) code execution
56     requests.
57 root 1.122 - do not use GMP for generating alphanumeric strings even when
58     available, use a more tricky algorithm instead.
59 root 1.121 - anonymous node names and remote port names have been shortened
60     considerably.
61 root 1.136 - $AnyEvent::MP::Kernel::SRCNODE contains the node ID of the origin
62     node during message receives.
63 root 1.122 - aemp shell now supports "package" selection and offers an
64 root 1.138 $ECHO port you can send messages to.
65 root 1.122 - rely on perl rand() instead of using /dev/urandom when available, as
66     hopefully it is random enough.
67 root 1.123 - aemp shell no longer leaks one port per command.
68 root 1.125 - nodenames can contain %-escapes such as %n or %u.
69     - aemp now uses aemp/%n/%u as nodename.
70 root 1.143 - configure supports "eval", a small perl snippet to initialsie a node,
71     most useful in "aemp run eval ...".
72 root 1.124 - known_nodes is gone, it has little value, use all_nodes as
73     replacement.
74 root 1.125 - lots of small change and improvements.
75 root 1.134 - node_is_known has been removed.
76 root 1.129 - TRACE now shows the portid on SND.
77 root 1.145 - aggressively reduce number of external modules, to reduce
78     memory usage for nodes.
79 root 1.146 - rework most of the documentation.
80     - clean up MP::Kernel exports.
81 root 1.158 - include AnyEvent::MP in AnyEvent::MP::Kernel's @CARP_NOT to
82     hopefully improve error messages.
83 elmex 1.115
84 root 1.114 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 root 1.107
88 root 1.113 1.29 Fri May 7 20:13:39 CEST 2010
89     - codename "Sadrak".
90 root 1.111 - fix error in callback at AnyEvent/MP/Global.pm line 339
91     (found by Sadrak).
92 root 1.108 - listener-less nodes had trouble sending keepalive
93 root 1.109 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 root 1.112 - do not overwrite the config file if we couldn't read it
98     for some reason (lesson demonstrated by Sadrak).
99 root 1.108
100 root 1.106 1.28 Thu Apr 1 21:23:54 CEST 2010
101 root 1.111 - accepted connections didn't correctly set up the SRCNODE
102 root 1.106 in some cases, leading to intra-node messages (such as monitoring)
103     to fail silently (great testcase by Sadrak).
104    
105 root 1.105 1.27 Sat Mar 20 21:11:16 CET 2010
106 root 1.101 - avoid exceptions in the transport code if the connection
107     fails during TLS negotiation.
108 root 1.102 - delay new address broadcasts in seednodes, to reduce the
109 root 1.103 likelyhood of nodes connecting at the same time, leading to
110 root 1.102 message loss.
111 root 1.104 - improve general message passing efficiency by 8%, and special
112     case json framing for a 50% speed increase.
113 root 1.99 - 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 root 1.100 - handle unsupported remote framings more gracefully.
117 root 1.99
118 root 1.98 1.26 Wed Dec 30 16:48:37 CET 2009
119 root 1.94 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
120     all nodes need to upgrade.
121 root 1.93 - remote kil's did not work (reported by Eugene Grigoriev).
122 root 1.94 - 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 root 1.96 - some doc updates.
126     - remote kil's were not synchronous to message sends which affected
127     nobody, as remote kils were broken.
128 root 1.97 - remote mon/unmonitor requests were not synchronous to message
129     sends either sometimes, although it likely didnt matter.
130 root 1.92
131 root 1.91 1.24 Wed Dec 9 14:59:52 CET 2009
132 root 1.87 - codename "the foul egg".
133     - increased "unmonitored local port died" message level to 2, so
134     it is displayed by default now.
135 root 1.89 - generate random seed at configure time, not module loading time,
136     so fork&configure works as expected.
137 root 1.88 - decreased "seed"-related message priority in Global from 0 (d'oh)
138     to 9, as they are not signifcant.
139 root 1.85 - new experimental module AnyEvent::MP::DataConn to establish
140     additional data connections between nodes.
141 root 1.84 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
142     to call restart.
143 elmex 1.86 - bin/aemp setcert didn't properly handle the filename argument.
144 root 1.90 - removed empty and unused timeout= parameter from protocol greeting.
145 root 1.44
146 root 1.82 1.23 Fri Nov 6 18:46:26 CET 2009
147 root 1.80 - 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 root 1.81 - 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 root 1.79 - 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 elmex 1.78
160 root 1.77 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 root 1.76 - added Coro::MP introduction to AnyEvent::MP::Intro.

173 root 1.72
174 root 1.71 1.2 Thu Oct 1 22:59:35 CEST 2009
175 root 1.70 - fix a rather big bug where message processing could be
176     inhibited completely.
177 root 1.65 - grp_mon could not return a guard due to a typo.
178 root 1.66 - implement primitive aemp shell.

188     - new function AnyEvent::MP::cal for simple rpc.
189 root 1.49 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
190 root 1.63 - implemented monitoring for Global groups.

194     it can return before invoking the init function.
195 root 1.55 - break endless recursion between ping-pong ports on the local
196     node after ~50 iterations.
197 root 1.47 - support JSON-encoded aemp arguments.

199 root 1.52 - support for starting init functions with parameters added.
200 root 1.53 - data_format, auth_offer and auth_accept are now configurable, albeit

202 root 1.54 - new service: AnyEvent::MP::LogCatcher.
203 root 1.58 - 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 root 1.61 - use seed nodes to notify nodes about new nodes.
208 root 1.63 - in the case where a ndoe learns new addresses after it tried
209     connecting, prefer the new addrseses over the old ones.
210 root 1.46
211 root 1.45 1.0 Wed Sep 2 20:40:43 CEST 2009
212 root 1.44 - randomise more connection times, but reduce delay to 0.2s (seeds)

220     pairs for configuration.
221 root 1.33 - give aemp a full manpage.

226 root 1.31 - nodes get freed when no longer needed.
227 root 1.35 - support "*" hostname to specify all local interface addresses

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