Starting Game Server results in segfault

Question

Starting Game Server results in segfault

mclayan opened this issue 7 years ago · 6 comments

I set up a new instance of dirtsand from scratch on a freshly installed Ubuntu server 17.04. Logging in and configuring my avatar works (mostly) fine but linking the first time to Personal will crash the whole server (as well as my bash). It happens every time I select my player after logging in with my account. This is the crash message of dirtsand:

Answer 1 · 2018-02-21T01:51:34.000Z

It looks like it's running into an issue merging the Global SDL state for the age with the age's local SDL state (both from the Vault). Is this on a clean vault db? Does the client's SDL match the server's SDL?

Answer 2 · 2018-02-24T14:44:09.000Z

@zrax
Yes, client and server share exactly the same .sdl and .age (and .fni) files. I dropped the whole database and re-created it, copied a set of files from a repository to the server and client, replacing existing files.
EDIT: here the latest crash log. Seems different this time:

Answer 3 · 2018-04-07T23:31:20.000Z

This appears to be an issue with string_theory's case insensitive hash or equals, @zrax. In my testing, when the client requests the Personal SDL, we ask the unordered_map for the Personal SDL. That SDL is present in the map, but the map doesn't return it.

Answer 4 · 2018-07-12T07:27:46.000Z

I'm guessing zrax/string_theory@be30cb2 might be a step towards fixing this

Answer 5 · 2018-07-12T15:30:36.000Z

It's actually highly doubtful, unless you have SDL filenames with non BMP/ASCII characters in them.

Answer 6 · 2018-12-02T23:50:40.000Z

Commenting to note that I experience the exact same issue (including call traces stemming from a segfault in SDL::State::merge()) as stated by the OP after compiling and running the latest dirtsand (plus latest string_theory) on a couple different machines (x86 ubuntu server 18.04, and arch linux ARM). Both used fresh databases built independently on each machine with the exact same results upon attempting to link to Relto after successful avatar customization.

Let me know if there's anything you'd like me to try on my end.
