Valentin Lorentz f8c5221efd do43x: add the current nick to the list of tried nicks.
The original nick was never added to the list...

Valentin Lorentz 6f6dad8f7b Add proper support for nested batches. 2021-03-03 23:32:00 +01:00
Valentin Lorentz 9719bb799e irclib: Send the bot user mode when advertized by the server
It is enabld by default in order to be a good netizen,
but can be overridden by admins if needed.

Valentin Lorentz 772ec8d6a9 When getting STS policy over insecure connection, reuse the exact same IP address
Otherwise, if some IP addresses don't work (eg. all odd ones), the bot will
consecutively fail because it can't connect, then connect + get STS + reconnect,
then fail again, then connect + get STS, etc.

I don't understand why it's happening or why it's only that specific test,
but there we go.

Valentin Lorentz c062787436 irclib: use a dedicated tag to detect emulated echo-messages, instead of receivedAt.
Plugins implementing inFilter do not set receivedAt, so incoming messages
rewritten by inFilter would be detected as echo messages, and ignored
by most plugins.

Valentin Lorentz 160bcc8b6b Revert "irclib: Fill the nick and prefix of simulated echo messages."
This reverts commit 1fe414764c.

I initially wrote that commit so that plugins with echoMessage=True can
get the nick/prefix from the message (eg. the SkypeRelay plugin in my
personal repo).
Unfortunately, this breaks any test that does equality comparison on
between the result of getMsg()/takeMsg() and an IrcMsg object they
crafted themselves.

Additionally, the filled in nick and prefix might be inaccurate if the
bot changes nick/host at the same time. So instead plugins should check
for the None value.

(Also, editing IrcMsgs on the fly like this isn't great, and the commit
forgot to reset the `_str` attribute.)

Valentin Lorentz 48b24769c2 irclib: Document classes better, especially instance attributes. 2020-09-27 15:51:01 +02:00
Valentin Lorentz 5d80b2eec9 irclib: Fix crash when MOTD is sent again later in the connection.
This can happen with this ZNC module: https://wiki.znc.in/Missingmotd
or if a plugin sends a 'MOTD' command.
2020-09-19 17:08:52 +02:00
Valentin Lorentz 0a6bb49fe6 irclib: Fix crash on CAP NEW.
Turns out, it wasn't tested so it never worked...
2020-09-19 16:55:51 +02:00
Valentin Lorentz 5dc72d2b34 Rename IrcCallback.echo_message to IrcCallback.echoMessage.
For consistency with 'alwaysCall' and 'noIgnore'.

Valentin Lorentz 0284ed9ebd irclib: Don't error when 004 is missing umodes and chanmodes. 2020-07-05 19:45:08 +02:00
Valentin Lorentz 6c4a8edb9c irclib: Ignore 'sts' in case of missing keys instead of aborting the connection.
In case https://github.com/ircv3/ircv3-specifications/pull/390 gets adopted.

Valentin Lorentz 568b84847b irclib: Fix hang in cap nego when echo-message is available but not labeled-response.
echo-message ended up in self.state.capabilities_req even though it wasn't
requested, so the bot was stuck in state:
"Waiting for ACK/NAK of capabilities: {'echo-message'}".
2020-05-18 20:50:14 +02:00
Valentin Lorentz e9a8826805 irclib: catch exception when calling callback.reset()
We don't want the Irc driver to hang when a plugin crashes
in this function.
2020-05-17 12:46:01 +02:00
Valentin Lorentz 759fca5eba Switch names of TimeoutDict and ExpiringDict.
For consistency, as TimeoutQueue has guaranteed deletion after the timeout,
like the new TimeoutDict (ex-ExpiringDict).
2020-05-10 08:42:25 +02:00
Valentin Lorentz eb1e27e20b Add echo messages, either with the echo-message capability or simulated.
Plugin can opt in to getting echo messages by setting the class attribute
'echo_message = True' if they want to get echos.
This defaults to False in order not to break existing plugins, and because
they usually don't need it (there's outFilter for most cases).
2020-05-07 21:08:07 +02:00
Valentin Lorentz 572c609181 Add labels to outgoing messages when labeled-response is supported.
This is going to be useful for implementing echo-message; and to plugins
targetting only networks with labeled-response support.
2020-05-07 20:56:59 +02:00
Valentin Lorentz 307a2367f4 Don't add line breaks in the middle of capability names. 2020-05-07 18:38:18 +02:00

They have their own 8191 bytes.

Valentin Lorentz da328b4985 Expire batches that never ended to avoid leaking memory. 2020-05-06 20:39:21 +02:00
Valentin Lorentz cc0af4e790 Include start and end messages in a batch.
They may have useful server tags (especially when we start
supporting labeled-response).
2020-05-06 18:29:17 +02:00
Valentin Lorentz a58c994954 Negotiate the 'setname' capability.
We don't store the name anywhere, but it can be useful to plugins.

Valentin Lorentz 309fc1233b Add postTransition method to IrcCallback, called when irc.state.fsm changes. 2020-05-01 20:19:53 +02:00
Valentin Lorentz f7130f2629 Add missing transition trigger on MOTD start. 2020-05-01 20:19:00 +02:00

Valentin Lorentz 51ff013fcc Apply STS policies when connecting to a server. 2020-05-01 19:46:19 +02:00
Valentin Lorentz ecc2c32950 Add support for storing STS policies.
If on an insecure connection: reconnect.
If on a secure connect: store it and do nothing else.

For now, stored STS policies are not read when connecting to an
insecure server.
2020-05-01 19:46:19 +02:00
Valentin Lorentz 45ff70907f [WIP] Start reworking Irc around a FSM.
To keep track of connection state instead of a complex implicit flow
between handling functions.
2020-05-01 19:43:27 +02:00
Valentin Lorentz e7553dcca4 Add subcommand dispatching for CAP/FAIL/WARN/NOTE. 2020-01-23 14:25:10 +01:00
Valentin Lorentz c4d073a9be Rename doAuthenticate* functions to not conflict with callback names. 2020-01-23 14:24:41 +01:00
Valentin Lorentz ac07b440dc Rewrite ecdsa-nist256p-challenge using python-cryptography instead of python-ecdsa.
Which is more secure. Closes GH-1389.

It also fixes the protocol/format to use the same one as Atheme.

Valentin Lorentz 84c1f1572d Don't temporarily set msg.channel to invalid values.
This causes issue when multiple command threads deal with the same message.
2019-09-20 21:25:32 +02:00
Valentin Lorentz c1ae3f5c81 all plugins: Use msg.channel instead of msg.args[0] + give network name to self.registryValue. 2019-08-24 23:35:01 +02:00
Valentin Lorentz 8bb31a54e7 Strip statusmsg chars in core to determine the actual channel.
Use msg.channel if relevant, otherwise strip them locally.
2019-08-24 14:52:59 +02:00
Valentin Lorentz 5b40b5136d Limit statusmsg prefix stripping to PRIVMSG and NOTICE. 2019-08-18 10:09:11 +02:00
Valentin Lorentz 7a7cdb9f05 Add a 'channel' attribute to IrcMsg objects.
It's nicer to use 'irc.channel' instead of 'irc.args[0]', and .channel
provides the actual channel name (stripped of the statusmsg prefix),
so it can be used by plugins when they want to use the actual channel
name.
2019-08-17 22:23:51 +02:00
Valentin Lorentz 696254ff1b Use irc.isChannel instead of ircutils.isChannel when possible.
It's aware of the network's 'chantypes'.
