Bug: rogomatic hangs sometimes due to using a potion, or scroll

[lcn2]

The player tool hangs a various times, while sometimes reading a scroll, or sometimes reading a potion, or shooting arrows at a monster, or at various other times.

The dungeon seed this happens on early seems to be highly dependent on the code. I.e., sometimes code mods will change when things hang.

Priority

Given recent edits and bug fixes, this problem appears to be the number 1 most common reason why rogomatic fails.

Suggestions

• Use the -d command line option when debugging as creating a new UTC date & time sub-directory will also cause player to start with an initial / default state. The rogomatic system is supposed to "evolve" over time, so without the -d command line option it may be harder to reproduce a problem.

• Make with either make clobber gcc or make clobber clang (depending on your local compiler) as this will turn OFF the optimizer, making it easier to debug.

• You may use killall player to terminate a hung setup, then reset to restore the terminal state.

UPDATE 0c

The archery fix seeks too work, the Hanging as a result of Quaffing a potion, and Hanging as a result of reading a scroll remain a problem.

As of commit 7d2b83e, much of the potion hanging and scroll hanging problems have been fixed. However, more test is needed and there seems to be some corner cases that need to be addressed.

Some seeds will hang due to some corner cases. See comments near the bottom for seeds that cause problems.

Partial "Good News Everyone" 🤓

With commit a399680, this hanging while Arching a monster appears to hav e been resolved using rogue version 5.4.5 release 2026-03-29.

The critical edit was:

Fixed how wield() in things.c tests if the currently wielded weapon is cursed,
and how it switches the weapon being wielded.

TODO

The other issues need to be addressed in order for this issue to be resolved.

The rogue process was still running, and so was player.

We suspect that the code in the wield() function in things.c is not working well with rogue. Perhaps the "current weapon might be cursed" check that issues the command (w^[) is not correct for the current versions of rogue?

Partial "Good News Everyone" 🤓

As of commit 7d2b83e, this hanging while Quaffing a potion appears to be mostly resolved.

There may be corner potion quaffing cases that still hang.

The critical edit was:

To create a state machine that can determine when issuing a "?\n;" is needed.

TODO

Continue to test.
