Summary0006114: When using channel mode history +H with modes-on-join it does not apply.
DescriptionValue of modes-on-join "+GntCKMfHL [30j#i10,40m#m10,7c#C15,10n#N15,30k#K10]:15 15:1440 #Full";

When you join a room it puts the CModes :

[25-05/23:54] * Now talking in #123
[25-05/23:54] * irc.extra-cool.fr sets mode: +ntCGKMfHL [7c#C15,30j#i10,30k#K10,40m#m10,10n#N15]:15 15:1d #Full

but we can notice a history.BUG_HISTORY_ADD_NO_LIMIT [warn] [BUG] hbm_history_add() called for #123, which has no limit set

now when I change the value manually:

[26-05/00:43] * Now talking in #321
[26-05/00:43] * irc.extra-cool.fr sets mode: +ntCGKMfHL [7c#C15,30j#i10,30k#K10,40m#m10,10n#N15]:15 15:1d #Full
[26-05/00:44] -irc.extra-cool.fr- operoverride.OPEROVERRIDE_MODE [info] OperOverride: [email protected] changed channel mode of #321 to: +PH 20:1h
[26-05/00:44] * ZarTek sets mode: +PH 20:1h
[26-05/00:44] <@ZarTek> Hello
[26-05/00:44] * Attempting to rejoin channel #321
[26-05/00:44] * Rejoined channel #321
[26-05/00:44] <ZarTek> Hello <= replay

It works. that's why I think it misapplies mode +H with modes-on-join. at least for the value (max-value) that it should not be loaded correctly

 *
 * To enable this you need to create a Secret block like this:

 *
 * To get better security, read https://www.unrealircd.org/docs/Secret_block

/*
 * UnrealIRCd has the following goals for storing channel history on disk:

 * - All data within the .db's is encrypted
 * - We use a well-known encryption library, a good cipher and KDF,
 * see Dev:UnrealDB for in-depth technical details.
 * - By default the log databases are stored in the data/history/ directory
 * - All .db files are cryptographically hashed so a third party can't tell
 * which .db file belongs to which channel
 * - A 'master.db' file is present too, to achieve the above in a consistent
 * and safe manner. Don't delete this file.
 * - Be sure to look at Secret block to see the various ways to store the key
 * (password) and pick one acceptable to your environment

Confirmed! When you set {{persist yes;}} and {{db-secret "historydb";}} and having {{modes-on-join "+H 15:1d";}} when you join on a channel, server sets the +H correctly but when you speak on channel then https://github.com/unrealircd/unrealircd/blob/unreal60_dev/src/modules/history_backend_mem.c#L598 is triggered.

 Seems +H was not working at all in set::modes-on-join indeed. Strange, I thought I tested that but i must have only tested it in +P then, I guess.

Anyway, thanks for the report! Fixed now.

commit fe11f77be6fca18907ffeee498af7101c2d91417 (HEAD -> unreal60_dev)
Author: Bram Matthys <[email protected]>
Date: Thu May 26 07:14:12 2022 +0200

    Fix +H not working in set::modes-on-join.
    Reported by ZarTek-Creole in https://bugs.unrealircd.org/view.php?id=6114
    
    We now call HOOKTYPE_LOCAL_CHANMODE on the modes we set in modes-on-join,
    where 'client' is '&me'. Should be fine, as we already did the same for
    +P modes (indirectly) in channeldb.
