On my Linux machine, init() is only called once, whether or not I open a database. Same goes with my Windows VM. I tested by writing to a file within init() to make sure I didn't miss any debug output.

@patateqbool Could you remove your "ugly hacks" in your next commit and close this issue? Thanks!

The previous fix seems to crash IDA in some cases.
Here are the steps to reproduce in order to reach the bug:
- cp /bin/ls /tmp
- open /tmp/ls with ida and close to create /tmp/ls.i64
- cp /tmp/ls.i64 /tmp/ls2.i64
- ida64 /tmp/ls.i64 & ida64 /tmp/ls2.i64
Open first /tmp/ls2.i64 and then /tmp/ls.i64, the first one should open correctly and the second one should crash.
@NeatMonster can you check this out ? Thanks !

SilverBut
commented on June 15, 2024
I can partially reproduce it in latest commit 1d345cc, using IDA 7.1 Linux.
However I don't think the plugin is loaded twice, since if you do this patch in idarling/inferface/plugin.py you can see while the initialize message and get me out message print out 2 times, the message already out only output 1 time.
Maybe someone wrongly used logging?

commented on June 15, 2024
@SilverBut Are you taking about this crash? I've found that the __init__ method from the plugin class is called twice if you're opening an IDB, but that init and term methods are only called once. But that shouldn't be an issue because all the real initialization stuff should be performed within init.
However, @patateqbool and I have been using this ticket to track other unrelated crashes (e.g. the backtraces), when we should have opened new issues instead. Sorry about that...
