22 root 1.118 2
23     - INCOMPATIBLE CHANGE: the node protocol used by this version is not
24 root 1.121 compatible to versions <2 - you have to upgrade all nodes.
25 root 1.124 - INCOMPATIBLE CHANGE: many APIs have changed, see the section
26     "PORTING FROM VERSION 1" in the AnyEvent::MP manpage for details.
27 root 1.121 - AnyEvent::MP::Global is now optional - only seed nodes autoload it
28     and create a fully-meshed network with each other, normal nodes only
29     have to connect to seed nodes, other connections are on-demand.
30 root 1.118 - new "norc" and "force" options for MP::configure to ignore
31     or override the rc file.
32 root 1.116 - move seed code to Kernel.
33 root 1.118 - fixed small typo in MP::Transport.
34     - fix (unused) provider-kv (version sometimes missing).
35     - reduce the default export list of MP::Kernel.
36 root 1.120 - reduced various random delays to zero, as they
37     are hopefully no longer needed with the new global
38     protocol.
39 root 1.126 - implement a secure mode that can suppress remote code execution
40     requests on a per-node/per-request basis.
41 root 1.122 - do not use GMP for generating alphanumeric strings even when
42     available, use a more tricky algorithm instead.
43 root 1.121 - anonymous node names and remote port names have been shortened
44     considerably.
45 root 1.122 - aemp shell now supports "package" selection and offers an
46     $ECHO port you cna send messages to.
47     - rely on perl rand() instead of using /dev/urandom when available, as
48     hopefully it is random enough.
49 root 1.123 - aemp shell no longer leaks one port per command.
50 root 1.125 - nodenames can contain %-escapes such as %n or %u.
51     - aemp now uses aemp/%n/%u as nodename.
52 root 1.124 - known_nodes is gone, it has little value, use all_nodes as
53     replacement.
54 root 1.125 - lots of small change and improvements.
55 elmex 1.115
56 root 1.114 1.30 Thu Jun 30 11:30:39 CEST 2011
57     - connection errors at the right time would kill node
58     connections in a bad way (patch by Malcolm Studd).
59 root 1.107
60 root 1.113 1.29 Fri May 7 20:13:39 CEST 2010
61     - codename "Sadrak".
62 root 1.111 - fix error in callback at AnyEvent/MP/Global.pm line 339
63     (found by Sadrak).
64 root 1.108 - listener-less nodes had trouble sending keepalive
65 root 1.109 messages on write timeouts (found by Sadrak).
66     - the monitor guard could cause a memleak due
67     to autovivification if a mon was cleared after
68     the port was gone (analysed by Sadrak).
69 root 1.112 - do not overwrite the config file if we couldn't read it
70     for some reason (lesson demonstrated by Sadrak).
71 root 1.108
72 root 1.106 1.28 Thu Apr 1 21:23:54 CEST 2010
73 root 1.111 - accepted connections didn't correctly set up the SRCNODE
74 root 1.106 in some cases, leading to intra-node messages (such as monitoring)
75     to fail silently (great testcase by Sadrak).
76    
77 root 1.105 1.27 Sat Mar 20 21:11:16 CET 2010
78 root 1.101 - avoid exceptions in the transport code if the connection
79     fails during TLS negotiation.
80 root 1.102 - delay new address broadcasts in seednodes, to reduce the
81 root 1.103 likelyhood of nodes connecting at the same time, leading to
82 root 1.102 message loss.
83 root 1.104 - improve general message passing efficiency by 8%, and special
84     case json framing for a 50% speed increase.
85 root 1.99 - add hints how to interface to aemp nodes from other programming
86     languages using the aemp protocol in AnyEvent::MP::Transport
87     (it can really be quite simple).
88 root 1.100 - handle unsupported remote framings more gracefully.
89 root 1.99
90 root 1.98 1.26 Wed Dec 30 16:48:37 CET 2009
91 root 1.94 - INCOMPATIBLE CHANGE: the high-level node protocol changed,
92     all nodes need to upgrade.
93 root 1.93 - remote kil's did not work (reported by Eugene Grigoriev).
94 root 1.94 - documented monitor_timeout, connect_interval, auth_offer,
95     auth_accept, framing_format, autocork and nodelay options
96     and make them configurable via bin/aemp.
97 root 1.96 - some doc updates.
98     - remote kil's were not synchronous to message sends which affected
99     nobody, as remote kils were broken.
100 root 1.97 - remote mon/unmonitor requests were not synchronous to message
101     sends either sometimes, although it likely didnt matter.
102 root 1.92
103 root 1.91 1.24 Wed Dec 9 14:59:52 CET 2009
104 root 1.87 - codename "the foul egg".
105     - increased "unmonitored local port died" message level to 2, so
106     it is displayed by default now.
107 root 1.89 - generate random seed at configure time, not module loading time,
108     so fork&configure works as expected.
109 root 1.88 - decreased "seed"-related message priority in Global from 0 (d'oh)
110     to 9, as they are not signifcant.
111 root 1.85 - new experimental module AnyEvent::MP::DataConn to establish
112     additional data connections between nodes.
113 root 1.84 - bin/aemp now loads AnyEvent::Watchdog::Util before trying
114     to call restart.
115 elmex 1.86 - bin/aemp setcert didn't properly handle the filename argument.
116 root 1.90 - removed empty and unused timeout= parameter from protocol greeting.
117 root 1.44
118 root 1.82 1.23 Fri Nov 6 18:46:26 CET 2009
119 root 1.80 - listener-less nodes were misinformed by their masters about
120     the location of new nodes, and therefore didn't connect
121     properly in all cases.
122 root 1.81 - messages send during node-up processing could sometimes get lost,
123     which would hamper global's ability to mesh the network.
124     - fixed AnyEvent::MP::Global::grp_reg to return a guard also
125     in scalar context.
126     - fixed AnyEvent::MP::Kernel::mon_nodes to return a guard also
127     in scalar context.
128 root 1.79 - try to improve error reporting when automatically loading
129     a function - being unable to load a module will now
130     stop the process and report the error.
131 elmex 1.78
132 root 1.77 1.22 Sat Oct 17 03:41:47 CEST 2009
133     - fix two rcv-bugs: after adding a tagged rcv, the default
134     callback would not be used or changed anymore (reported
135     by Felix Antonius Wilhelm Ostmann, with apologies for
136     taking so long to releae the fix).
137 root 1.76 - added Coro::MP introduction to AnyEvent::MP::Intro.
138 root 1.75 - add peval function.
139    
140 root 1.74 1.21 Mon Oct 5 21:58:36 CEST 2009
141 root 1.72 - always delay kil messages.
142 root 1.74 - remote monitor requests were never cleaned up (found by
143     Sadrak and analysed by elmex).
144     - move $VERSION to AnyEvent::MP and AnyEvent::MP only.
145 root 1.72
146 root 1.71 1.2 Thu Oct 1 22:59:35 CEST 2009
147 root 1.70 - fix a rather big bug where message processing could be
148     inhibited completely.
149 root 1.65 - grp_mon could not return a guard due to a typo.
150 root 1.66 - implement primitive aemp shell.
151 root 1.67 - do not use bound address as listen length (reported by

154 root 1.69 - the mon_guard return value no longer keeps an additional
155     reference to the passed refs.

157 root 1.64 1.1 Fri Sep 11 04:34:03 CEST 2009

159     were too many bugfixes/changes.
160     - new function AnyEvent::MP::cal for simple rpc.
161 root 1.49 - renamed AnyEvent::MP::Global functions to grp_reg|get|mon.
162 root 1.63 - implemented monitoring for Global groups.
163 root 1.50 - removed all userspace time-outs from the transport, instead
164     rely on tcp retransmit timeouts and tcp keepalive.
165 root 1.48 - spawn now delays spawns on the local node artificially, so
166     it can return before invoking the init function.
167 root 1.55 - break endless recursion between ping-pong ports on the local
168     node after ~50 iterations.
169 root 1.47 - support JSON-encoded aemp arguments.

175 root 1.58 - rely on perl srand'ing better than we could.
176     - try to backport to 5.8.2, unfortunately, recursive dependencies
177     rely on Module::Build, which fails at 5.8.7, so YMMV.
178     - use a vastly different reseeding strategy.
179 root 1.61 - use seed nodes to notify nodes about new nodes.
180 root 1.63 - in the case where a ndoe learns new addresses after it tried
181     connecting, prefer the new addrseses over the old ones.
182 root 1.46
183 root 1.45 1.0 Wed Sep 2 20:40:43 CEST 2009

198 root 1.31 - nodes get freed when no longer needed.
199 root 1.35 - support "*" hostname to specify all local interface addresses
200     (without localhost etc.).

204 root 1.30
205 root 1.29 0.9 Sat Aug 29 18:47:45 CEST 2009
206     - tutorial was updated to reflect the current API, but
207 root 1.43 does not touch monitoring yet.

209 root 1.25 free-text node identifiers and anonymous nodes.
