WAD/zip file name format causes spawn location bug

[Clayman_Colony]

I found a strange bug in GZDOOM G4.13.2 on Linux (might not be limited to Linux systems though if someone else wants to replicate) also present in the latest dev build gzdoom-linux-x64-g4.15pre-1-gd61ec1722.tar.xz

If I rename a zipped WAD file a certain way it causes you to spawn in the wrong location when you start the first map (perhaps others also) even when restarting the map in game (no mods or anything else loading, just the map):

File names (RENAMED AS BELOW) causing spawn location bug I suspect:

• Miasma - D2, SM, 2016, Cacoward.zip

https://www.doomworld.com/idgames/level ... m-o/miasma

• Eviternity II Final - D2, MW-36, Dragonfly et al, 2024, Cacoward.zip

https://www.doomworld.com/idgames/level ... iternityii

Simply adding an "s" to the end of "Cacoward" making it "Cacowards" seems to make it work again. The problem is that I'm not sure what else can be broken by file names that might not be as obvious eg: monsters spawning in wrong locations or not spawning at all or scripts breaking - at least some other maps spawn correctly, but who knows what else is broken then. It is a strange problem and I cannot figure out the real pattern that breaks things. For example, I renamed Miasma to "Test - A2, B, 2016, Cacoward.zip" and that works. There is some underlying file name pattern bug at play breaking WADs. I could not see obvious errors or differences between in the console in any tests though someone might want to re-check that.

I also tried swapping the "broken" file names between Miasma and Eviternity II and they work fine then so it appears the file name bug is tied to the WAD/zip file itself as the "broken" name applied to another WAD/zip does not seem to break it. I downloaded fresh copies to make sure the zip wasn't broken in some way.

It appears if you extract the zip and rename the WADs mentioned earlier to the "broken" file names it works again (though there might be other name patterns that potentially breaks them). Not an ideal work around to have to unzip everything into folders and also the given possibility of file names breaking things is not a good to have.

The problem is also present when not using any launchers like Doom Runner.

Eviternity II correct start spawn location for the first map:


Eviternity II incorrect start spawn on the first map due to file name "Eviternity II Final - D2, MW-36, Dragonfly et al, 2024, Cacoward.zip" and perhaps other file name patterns:

Please post your startup log. The container's file name should not affect its contents, but of course it may cause a file from a different location to be loaded.
In addition, please run 'mapchecksun' for the affected maps at the console to make sure they are identical.

I tried looking up how to export a text version of the startup log but could not find instructions so had to do screenshots again sorry. I switched back and forth between them quickly and could not see any relevant differences. These tests were done with the same file with only the zip file name being changed as per the original post:

Other source ports like DSDA did not have any issues that I noticed. Again I am not sure if any of this is replicable on non-linux systems.

Add +logfile log.txt
to the command line (in a shortcut, or a batch file, or adding it to the parameters of a launcher if you use one, or just at the cmd prompt).

This will save all console output to the file log.txt. You can specify a different name or a path if you want to.

e.g. gzdoom +logfile c:\doom\mynewlog.txt

[Clayman_Colony]

Add +logfile log.txt

Thanks for that, I appreciate the tip.

Quick side note: The bug manifesting in the Miasma example is also present in LZDoom so I don't think this is a recent bug - I tried Eviternity II in LZDoom but that does not even load. There is definitely some underlying bug regarding how GZDoom is handling zip files would be my guess unless it is not replicable on other Linux machines.
