Well, not quite the same functionality. module:add_timer() would cancel the
timer if the module got unloaded while processing. This would leave the async
runner hanging forever. The new code would let it finish.]]> Matthew Wild <mwild1@gmail.com> Sat, 06 Dec 2025 16:00:22 +0000 http://hg.omfa.de/prosody-hg/log/9cfc62b4625b/plugins/mod_mam/mod_mam.lua
To prevent modern MAM-capable clients from receiving messages twice (MAM +
offline), Prosody has long suppressed offline messages for clients that
query the MAM archive before initial presence (which is the trigger for
sending offline messages).

From Conversations 2.19.2, it is now sending MAM queries before initial
presence, apparently for the first time, triggering the Prosody feature.

However, this has caused some undesired observable effects in certain edge
cases.

For example, if MAM is enabled on the server, but the user has disabled
archiving for their account, their archive may be empty while they have
actually have pending offline messages.

The long term goal remains to move towards smart retention in MAM, and
the deprecation and removal of the legacy offline messages mechanism.]]> Matthew Wild <mwild1@gmail.com> Thu, 04 Dec 2025 11:12:23 +0000 http://hg.omfa.de/prosody-hg/log/24252947a8ca/plugins/mod_mam/mod_mam.lua Kim Alvefur <zash@zash.se> Sun, 23 Mar 2025 19:59:45 +0100 http://hg.omfa.de/prosody-hg/log/1a8e47d42264/plugins/mod_mam/mod_mam.lua Kim Alvefur <zash@zash.se> Sun, 23 Mar 2025 19:57:06 +0100 http://hg.omfa.de/prosody-hg/log/f424c9f1460b/plugins/mod_mam/mod_mam.lua

Changes sub-second part of example timestamp to .5 in order to avoid
floating point issues.

Some clients use timestamps when ordering messages which can lead to
messages having the same timestamp ending up in the wrong order.

It would be better to preserve the order messages are sent in, which is
the order they were stored in.]]> Kim Alvefur <zash@zash.se> Sun, 14 Aug 2022 17:28:31 +0200 http://hg.omfa.de/prosody-hg/log/706375b75475/plugins/mod_mam/mod_mam.lua Kim Alvefur <zash@zash.se> Tue, 14 Jun 2022 22:06:21 +0200 http://hg.omfa.de/prosody-hg/log/519e6403f455/plugins/mod_mam/mod_mam.lua
