It seems like a macOS bug related to strcoll and LC_COLLATE

Add an extra environment `LC_COLLATE="C"` can bypass this bug.

Recent update 663947 tried to use `stringidsorter` in `table.sort` which utilizes `strcmp`. However it seems there is some other bugs in stringidsorter..

print(stringidsorter("AO", "Ao")) -- false
print(stringidsorter("Ao", "AO")) -- false

 

The `strcoll` thing is interesting. I tried to trigger the bug in some minimal C code between MacOS and Linux but results were identical, tried with LC_ALL/LC_COLLATE set to C or an UTF-8 locale, with or without setlocale(LC_ALL, "") in the code beginning etc. but sorting of "exitgym" with regards to other values was the same.

Wondering if Apple instead fixed a bug or something, or my test setup is not capturing whatever behavior changed.

Because I'm way too curious with too much time on my hands, I snooped in a bit even though this is all irrelevant by now with regards to this bug......but maybe somewhere out there, some project also hits this strcoll() bug and they put that in Google, and then they find this post because I'm using many technical words they might put in a search

In Ghidra I can see the MacOS version of the game (and critically ONLY MacOS) has code that calls _setlocale(0, "") (which I think is same as setlocale(LC_ALL, ""), LC_ALL is a zero constant on Mac, but Ghidra is unable to tell me if it's actually called; it seems far removed from wherever main() entrypoint is in DST. (Screenshot from Ghidra).

But Linux version, in Ghidra I cannot see any calls to setlocale using this tool. I even tested a simple symbol stripped executable (same as strcmp_test below in my test setup) in Ghidra to see should it be visible even in symbol-stripped binaries and answer was yes, I should be able to see a setlocale.

My hypothesis (not sure if any of this is true but making my best guess):

1) DST does not call setlocale(LC_ALL, "") on other platforms, save for MacOS. The fact that MacOS version has a call to it according to Ghidra is because it's part of some MacOS-specific library DST uses, or there is code in DST that only is compiled in on MacOS that incidentally also sets the locale. Other editions do not set the locale. Setting the locale affects behavior of strcoll() so the question of setting locale or not is key part of this conundrum.

2) Apple fixed a bug in strcoll(). It used to work incorrectly and did not actually take locale into account at all. Since MacOS DST calls setlocale(LC_ALL, "") (unlike the other editions), it now uses the correct behavior of strcoll(). I'm guessing this because the behavior looks identical on Linux/MacOS in my tests below. If I had access to an older Mac, I could verify if this guess is correct. Alternatively, some totally unrelated change in Sequoia 15.4 made DST take a code path that does the setlocale() thingy and made it trigger the case-aware strcoll() and its behavior has not actually changed. (I tried to Google for similar issues in other projects...did not find any mentions).

I noticed in Lua source code it indeed uses strcoll() internally. I had never even seen or heard of strcoll() until @Hubert Zhang mentioned it

Test setup for people who have way too much time and curiosity on their hands

If anyone is curious enough and has an older Mac, you can try replicate my setup. I wrote one C file (strcmp_test.c) and a shell script (run_strcmp_strcoll_test_thingy.sh) to try combinations. The only difference I found between Linux/macOS is that the numerical value is different for collating cases but it's different in a way that would not affect sorting. I compared "exitgym" and "GetChatHistory" because they were next to each other in the RPC code listings.

It's a shame I don't have an older version of Mac to run this on. If my hypothesis above is correct, I'd expect to see identical behavior to strcoll()/strcmp() on Mac on every test case.

// strcmp_test.c
// Purpose: Compares two strings with strcmp/strcoll and
//          is meant to be ran off a shell script running
//          with varying locale setup.

#include <stdio.h>
#include <stdlib.h>
#include <locale.h>
#include <string.h>

int main(int argc, char **argv)
{
    if (argc != 4) { fprintf(stderr, "Usage: strcmp_test [t|f] <string1> <string2>\n"); return 1; }

    if (argv[1][0] == 't') {
        setlocale(LC_ALL, "");
    } else if (argv[1][0] == 'f') {
        // intentionally empty
    } else {
        fprintf(stderr, "Bad first argument; use t or f.\n");
        return 1;
    }

    int result_strcmp = strcmp(argv[2], argv[3]);
    int result_strcoll = strcoll(argv[2], argv[3]);

    const char* lc_all_env = getenv("LC_ALL");
    const char* lc_collate_env = getenv("LC_COLLATE");

    printf("--- TEST ---\n");
    system("uname"); // Prints "Darwin" on mac, "Linux" on linux
    printf("getenv(LC_ALL) = %s\n", lc_all_env);
    printf("getenv(LC_COLLATE) = %s\n", lc_collate_env);
    printf("setlocale(LC_ALL, \"\") has been called: %s\n", argv[1][0] == 't' ? "yes" : "no");
    printf("  strcmp(\"%s\", \"%s\") = %d\n", argv[2], argv[3], result_strcmp);
    printf("  strcoll(\"%s\", \"%s\") = %d\n", argv[2], argv[3], result_strcoll);
    return 0;
}

Shell script:

#!/usr/bin/env bash

# Compile strcmp_test first manually with either:
# clang -Wall -arch x86_64 strcmp_test.c -o strcmp_test  # (Mac, and x86_64 to match Don't Starve)
# gcc -Wall strcmp_test.c -o strcmp_test                 # (Linux)

# First two tests: with LC_ALL set to unicode locale and no LC_COLLATE
export LC_ALL=en_US.UTF-8
unset LC_COLLATE
./strcmp_test t exitgym GetChatHistory
./strcmp_test f exitgym GetChatHistory

# Second two tests: with LC_ALL set to C locale
export LC_ALL=C
./strcmp_test t exitgym GetChatHistory
./strcmp_test f exitgym GetChatHistory

# Final tests, no LC_ALL set at all
unset LC_ALL
./strcmp_test t exitgym GetChatHistory
./strcmp_test f exitgym GetChatHistory

#             ^
#             |
#             +--- The t or f here affects if strcmp_test will call
#                  setlocale(LC_ALL, ""). The program will print if it did so.

Output from both Mac and Linux:

...Oh and also I confirm everything seems to work now. I did clean slate install without any of my hacks and moving works and I can use the Wendy flower as well. Thanks for the fix!

and if any of you did read the ramblings of my previous post though then thanks for coming to my TED talk I shall take my exit now

Just turn off Game Mode. The game server runs as a separate background process, and Game Mode limits the CPU usage of background programs, which causes stuttering.
