Bram Matthys c0b86c757c Change chanmode +H parameter to show hours and days when needed and
possible if it rounds off nicely, eg +H 100:7d. Note that the
existing syntax is still accepted, eg +H 20:1440 and +H 20:1440m
are both converted to 20:1d.

With potentially higher time values this change makes the mode
parameter a lot more readable.

Support for translating timevalues is already in UnrealIRCd 5.0.2
and higher, so should be fine for nearly everyone.

Bram Matthys c6873292b9 Implement CHATHISTORY TARGETS...
Except that it still needs to order the result by timestamp,
which it does not do at the moment.

Bram Matthys 937cc94940 Add CAP draft/chathistory and don't send history-on-join if this
CAP is enabled by a client.

Bram Matthys abeb222eed Implement CHATHISTORY BETWEEN 2021-05-22 11:50:51 +02:00
Bram Matthys 188dc7792d Fix crash on remote CHATHISTORY cmd (by servers/services). 2021-05-21 07:20:26 +02:00
Bram Matthys cda145b62a Add initial version of CHATHISTORY command
from https://ircv3.net/specs/extensions/chathistory

Current status of the module in UnrealIRCd:
* A significant part of this is done and working
* Currently in modules.optional.conf to get test exposure,
  not yet loaded by default.
* CHATHISTORY subcommands implemented: BEFORE, AFTER, LATEST, AROUND
* It does not implement the subcommand "BETWEEN" yet
* It does not announce or recognize the (draft) CAP's yet
* It does not announce the ISUPPORT token CHATHISTORY=xx yet
* Testcases need to be written to validate everything
* There will be bugs, now, and also while implementing the rest
  in the days to come.

Bram Matthys be81152da7 Move hash generation outside cfg() and do it early just to be safe. 2021-05-17 12:38:43 +02:00
Bram Matthys 8c71cd1a65 * Make channeldb write the db on terminate
* Fix channel history issues with writing on terminate
* Change tkldb and reputation to only write the db
  on terminate and not on every REHASH anymore

..all this thanks to the new loop.ircd_terminating, so modules can
see the difference between regular rehash and terminating.

Bram Matthys ae873ab25a Compile fixes for Windows 2021-05-16 19:15:01 +02:00
Bram Matthys f79fec62f1 Add CAP unrealircd.org/history-backend which declares the policy/
configuration on how history is stored (in memory and/or on disk).
This is similar to other disclosing policies like
unrealircd.org/link-security and unrealircd.org/plaintext-policy.
The reason for this cap (and similarly the other caps) is that
the user can make an informed decision on whether it finds the
policy/safety/privacy of an acceptable level or not.

Fixes for turning persist on/off on the fly (REHASH)

Make release notes a bit more clear.

Bram Matthys 3bf0c9e653 Add support for persistent channel history, if the channel is +P and +H.
This is not enabled by default and requires additional configuration,
documentation will follow later.

Bram Matthys deffc908e3 Document UnrealDB API and get rid of unrealdb_write_data/unrealdb_read_data.
API users must use specific size/type functions instead, otherwise it is
simply too dangerous / too easy to overlook issues.

Bram Matthys dd33b38264 Fix extended server ban ~a:accname not working for shun and also
not always kicking in on *line either.
We now check for shuns/*lines in user_account_login(), so upon
SASL or NS IDENTIFY etc. This also means that the client could
now be killed in that function, so callers should take extra
care and take that into account. We check for IsDead() in our
calls now (if it's our client anyway).

Hopefully this doesn't break anything.........
2021-04-17 14:42:40 +02:00
Bram Matthys d6b0981433 Module coders: Update HOOKTYPE_LOCAL_NICKCHANGE and HOOKTYPE_REMOTE_NICKCHANGE.
I forgot to include message tags earlier, so this is a breaking change:
-int hooktype_local_nickchange(Client *client, char *newnick);
-int hooktype_remote_nickchange(Client *client, char *newnick);
+int hooktype_local_nickchange(Client *client, MessageTag *mtags, char *newnick);
+int hooktype_remote_nickchange(Client *client, MessageTag *mtags, char *newnick);

Be sure to update your hooks!
You can use something like: #if UNREAL_VERSION_TIME>=202115
2021-04-17 10:38:25 +02:00
Bram Matthys e596b730af Move channel history sending from one layer to the other.
This so for example history_backend_mem() does not do any sending.
Less efficient but needed for later when things get more complex.

Bram Matthys 775c00c096 Add displaying of reputation score in WHOX (if IRCOp).
The new display field is called 'R', use something like:
WHO * %cuhsnfmdaRr

At the moment only "displaying" is available and not "searching"
on reputation. If you need that, you're stuck with the /REPUTATION
command at the moment. Too much hassle to implement that.

Bram Matthys 0ea86fce83 Forbid using extended server bans in ZLINE/GZLINE as they only work on *@IP.

Bram Matthys d9fbb51a33 Fix error message for /ELINE not working with certain types.
Reported by westor in https://bugs.unrealircd.org/view.php?id=5843

This makes the code more generic so it's just adding a 1/0 in
the TKL types table.

Bram Matthys 4bd0969583 spamfilter { } blocks caused some confusing whitespace in stats for
the spamfilter. Only after a rehash it showed the me::name as the
setter. From now on we just display -config- in the setter field,
like we do for all the other TKLs as well (ELINE, ban xyz, etc).

Bram Matthys 17bdd6de1e Use different temporary filename. Not really important normally but
if running multiple ircds from the same directory you sometimes get
weird messages otherwise (not that we really support such a thing
but i use it while dev'ing).
2021-03-06 18:55:10 +01:00
Bram Matthys dc40d27cd8 Move set::anti-flood::unknown-flood-* to set::anti-flood::handshake-data-flood
which is a new block, documented at:
https://www.unrealircd.org/docs/Set_block#set::anti-flood::handshake-data-flood
The reason for this is better naming and allowing to tweak ban-action.
2021-02-28 07:52:33 +01:00
Bram Matthys 94b8f6575e Just some code cleanup (variable renaming) in tkldb, nothing more...

Bram Matthys 9e82f13c54 Fix bug in tkldb if ircd is rehashed every <300 secs it would never save.
Not reported by anyone, but yeah.. who knows there is someone out there
that does this :D.
Also make it work the same like channeldb by spreading the event.

Bram Matthys c71214cefe Rename nvplist functions to match the rest, fix resource leak,
and move the functions to list.c where they belong.

Bram Matthys 1baf5f9f7d Show reputation score and some other info in "Client connecting"
notices to IRCOps and in ircd.log.
See the release notes for more details.

Module coders:
You can use HOOKTYPE_CONNECT_EXTINFO to add your own additional
information as well. See get_connect_extinfo() for inspiration.
Use nvplist_add() or nvplist_add_fmt() to easily add your info
to the list.

Module coders II:
Small note: this moves the sending of the far connect notice
to /under/ HOOKTYPE_REMOTE_CONNECT instead of /above/.

PeGaSuS e90d661e8d Fixed typo in ELINE example flags, from f to F (spamfilter) (#130) 2021-01-29 19:11:36 +01:00
Bram Matthys 3a922d6ed5 Disable handshake delay for users that are exempt from blacklist checking.
The handshake delay exists so results from DNSBL's can be checked before
the user is fully online. Whenever someone is exempt from DNSBL checking
it serves no purpose, so we mark it that the user has no handshake delay.
This will speed up connecting by up to 2 seconds (by default).
Also updated WebIRC example to suggest this now:

Bram Matthys cd967a6ea6 Always exempt 127.* from gline, kline, etc.
The exempted ban types are only ones that will affect other connections as well,
such as gline, and/but not policy decissions such as bypassing qlines or maxperip.
Currently the list is: gline, kline, gzline, zline, shun, blacklist,
                       connect-flood, unknown-data-flood.
