redbean: LaunchBrowser not working on macos

[mika76]

redbean 1.5 macos big sur 11.6

If I add in an index.html file then it works fine and I get the server running, but as soon as I add the command LaunchBrowser() to the .init.lua file, it fails with:

error: Uncaught SIGSEGV (SEGV_MAPERR) on Mikas-Mac-Pro pid 5793
  ./redbrean.com.zip
  ENOENT[No such file or directory][2]

I've tried with paths "/" and "/index.html" and "index.html" but they all fail with the same issue.

[pkulchenko]

@mika76, this doesn't seem to be related to LaunchBrowser, as any external request fails for me. redbean 1.5 works on older versions (Mac Mini 2012 - Intel i7 - 10.15.7), but doesn't work on a newer one (MacBook Pro 2021 14” - M1 Max - macOS 12.0.1). I suspect it may be related to Rosetta emulation, but I'm not sure if it's used in your case or not (it's used in mine on 12.0.1).

@jart, here is the full crash report:

I did a bit of troubleshooting and it looks like it's crashing in the HandlePoll function and it looks like it doesn't come back from the signal handler correctly. I'm not sure how to debug it further. I tried to run it with a debug build, but ran into a different issue trying to launch redbean:

libc/intrin/asan.c:1147: assert(!OverlapsShadowSpace((void *)p, n)) failed

[mika76]

@pkulchenko My macbook is a 2019 x86 based one - not m1 so I don't think it's rosetta in my case...

[pkulchenko]

Do you get the same SIGSEGV when you access the URL without LaunchBrowser command?

[mika76]

With just a single LaunchBrowser() command...

Do you get the same SIGSEGV when you access the URL without LaunchBrowser command?

Nope - works fine - although I've only just started playing with redbean so I haven't tried much...

[pkulchenko]

@mika76, interesting; can you launch the same command with -vvv options? there should be some additional information in the logs from the LaunchBrowser command. Also, does it actually launch the browser?

, does it actually launch the browser?

Nope, just crashes back to the prompt

[pkulchenko]

Hm, there are not that many lines where it may fail, given that it doesn't even get to the DEBUGF call:

  if ((prog = commandv(GetSystemUrlLauncherCommand(), gc(malloc(PATH_MAX))))) {
    u = gc(xasprintf("http://%s:%d%s", inet_ntoa(addr),
                     ntohs(serveraddr->sin_port), gc(EscapePath(path, -1, 0))));
    DEBUGF("(srvr) opening browser with command %`'s %s", prog, u);

If you're compiling from source, can you add a couple of print statements inside LaunchBrowser to see where exactly it fails?

[badiku]

same on windows10

[pkulchenko]

@mika76, @badiku, can you check if this patch fixes the issue: https://github.com/pkulchenko/cosmopolitan/tree/redbean-fix-browserlaunch? It does fix the issue for me on Windows, but the explorer still fails to launch with error code 5 returned and I can't yet figure out why.

[mika]

@pkulchenko you pinged the wrong mika ;)

[pkulchenko]

Ha, thanks; fixed.

[pkulchenko]

@mika76, let me know if you had a chance to test the patch in https://github.com/jart/cosmopolitan/issues/337#issuecomment-1002434246 and if it worked for you; not sure if you saw the update. Thanks!

[mika76]

Hey @pkulchenko nah I haven't played with this since then - I'll see if I can try it out sometime and will post here...

[jung-kurt]

Nice work, @pkulchenko -- your change 82d62e76fd6abc3b3edb840a814cb22f12f7ad05 corrected the LaunchBrowser() problem for me on Ubuntu.

[pkulchenko]

Thank you for checking! Submitted a PR #359.

[imaitland]

I am seeing this issue on MacOs. calling LaunchBrowser('/foo') from .init.lua fails.

I can confirm that just doing: open https://google.com in my terminal works as expected, (opens browser at google.com), so not sure what the ENOSYS[Function not implemented][78] might be. Happy to debug myself with a bit of direction if available.

This appears to be a slightly different issue. What version of Redbean are you using and did you download it or built yourself? Also, what version of macOS are you on? I may be able to check later today.

[imaitland]

Redbean 1.5 from: curl https://redbean.dev/redbean-latest.com >redbean.com

macOS Big Sur version 11.6.5

MacBook Pro (Retina, 15-inch, Mid 2015)
2.2 GHz Quad-Core Intel Core i7

@imaitland, yes, that fix wasn't in 1.5, as it was introduced later, after 1.5 was already released.
