Mob Spawns Disappearing

Temporary code to track and prevent the multiple remove_map's was added in [rev=12430].

Issue is most likely still present in rAthena. Here are some debug messages produced by the tracking code:

I'd appreciate rA server owners to check their logs for similar debug messages, to make sure problem is not fixed yet.

This is very bad, it's happening in WoE maps The WoE script seemed broken by the way, it didn't always respawn people out of the castle... but we don't know if it's related to that problem.

I have the full console server log in a file. If you need to search for other Debug messages I'll grep'em for you [img]http://www.eathena.ws/board/style_emoticons/default/smile.gif[/img]

I did a further extension of the debug message by myself, to figure out, what is calling unit_remove_map_pc. It turns out, that it is called from the same position in pc_setpos.

x = y = 0; // make it random
}

if( x == 0 && y == 0 )
{// pick a random walkable cell
do {
x=rand()%(map[m].xs-2)+1;
y=rand()%(map[m].ys-2)+1;
} while(map_getcell(m,x,y,CELL_CHKNOPASS));

Once again digging this up, still cannot reproduce it intentionally, but could further track where both calls are coming from. Both calls start in unit_walktoxy_timer and go along through npc_touch_areanpc->pc_setpos->unit_remove_map_pc->unit_remove_map.

/src/map/unit.c (r127xx):[/size][/color][color=#000000][b]
CODE[/b][/color][color=#465584][font=Courier,]
static int unit_walktoxy_timer(int tid, unsigned int tick, int id, intptr data)
{
[...]
if(sd) {
if(map_getcell(bl->m,x,y,CELL_CHKNPC)) {
npc_touch_areanpc(sd,bl->m,x,y); // <--
if (bl->prev == NULL) //Script could have warped char, abort remaining of the function.
return 0;
} else
sd->areanpc_id=0;
if (sd->state.gmaster_flag &&
(battle_config.guild_aura&(agit_flag?2:1)) &&
(battle_config.guild_aura&(map_flag_gvg2(bl->m)?8:4))
)[/font][/color]

Dunno how to track it further, hope this may help.

[u][b]How to reproduce[/b][/u]

1) Cast AL_WARP (warp portal) on the very edge of a warp area_npc. The destination is of no importance.
2) Wait for the portal to become active.
3) Use cloaking.
4) Walk to the tile with the warp portal (and warp npc).
(this can be done with two characters by "legitimate" players.)

[u][b]Reconstruction[/b][/u]

As the character arrives at the destination tile, warp portal will trigger. It is important to note that this happens despite being in cloaking state. The issuing map change will end the cloaking state. Ending cloaking will in turn trigger nearby area npcs, thus activating a second warp inside the code of the first. Thus unit_remove_map will re-enter and print the warning/double decrement the map user counter. The character will arrive at the second destination, while the first will receive the faulty user count.

[b][u]Stacktrace[/u][/b]

The first call to unit_remove_map. Note status_change_end in there.

And for completion's sake, this is the second call. Note that it's exactly the same call as the lower part of the first.

[u][b]Proposed Solution[/b][/u]

This is a delicate issue, and I'm afraid I'm not too familiar with the inner workings of the unit code as of yet. My initial instinct was to end the statuses after map change instead of before, but the number of scenarios (especially pc vs non-pc) and potential side effects are huge. For one, the client would no longer properly display the character uncloaking when doing so on top of a warp. My second idea would involve making non-re-entrant version of status_change_end. I'm sure a better solution exists, however, and will see if I can come up with one. If you have any input, please share it! I hope I was of help.

[u][b]Additional Concerns[/b][/u]

It is entirely possible that other scenarios exist for the same issue. I sifted though most of the code surrounding it, but was unable to spot anything at first glance.

Wildcard

After extensive testing, on and off my live server (400-500 players online) to ensure this fix won't affect anything else, I've come up with the following fix. Fixed in [rev=16434]. Not experiencing any issues with dynamic mobs not spawning due to the -1, as well.

Edit:
Not an end-all-be-all to the issue (in my opinion, as Wildcard pointed out), but it surely resolved the "[font=Arial, Verdana, Tahoma,][font=Courier,]unit_remove_map: unexpected state when removing player" jazz and issues with mobs not spawning (the original issue at hand).[/font][/font]
