ladybird on NetBSD #23375

0-wiz-0 · 2024-02-27T17:41:03Z

I tried packaging ladybird for pkgsrc and tried following the Custom CMake build directory instructions from https://github.com/SerenityOS/serenity/blob/master/Documentation/BuildInstructionsLadybird.md but fail quite soon (directly after configure) when various Python scripts are called and want to create files in directories that do not exist (yet?).

I though that perhaps it's caused by me building highly parallel, but even with a single job it fails with:

with more jobs in parallel, here are some more of the problems:

For the last example, which has a complete path, I see that the path up to LibGfx exists, but not the ImageFormats subdirectory:

# ls work/serenity/cmake-pkgsrc-build/Lagom/Userland/Libraries/LibGfx/
CMakeFiles            Makefile              cmake_install.cmake

Please advise, thank you!

The build with the default Unix Makefiles generator has been broken for a while, I think. Can you try using the ninja generator?

cmake <.... arguments> -GNinja

0-wiz-0 · 2024-02-27T18:07:09Z

Thanks for the comment.
I've tried that too, but see an endless loop of these messages:

The combination of cmake + ninja in pkgsrc usually works fine, but I had to disable it for two other projects too. I suspect a timestamp problem, but I have no clue how to debug this.

Update: It's not endless, it's just very long, and then it fails with:

so that's progress :)

ADKaster · 2024-02-27T18:18:43Z

We just recently (like, literally yesterday) added the calls to secure_getenv in that file. What OS is this? Does it have that function? Or are we just missing an include

I'm compiling on NetBSD.
As I understand it, both functions are glibc extensions and should be hidden by ifdef(__linux__).
I use this for now:

ADKaster · 2024-02-27T18:29:22Z

so we don't have many people compiling for NetBSD, so this is kinda expected. FreeBSD is going ok it seems, as they have a port in their tree.

fwiw FreeBSD 14 seems to have secure_getenv https://man.freebsd.org/cgi/man.cgi?getenv(3)

we have macros like AK_OS_NETBSD already, from AK/Platform.h

Regarding executing binaries from the build, that's supposed to work via RPATH. if pkgsrc hates RPATH, then it's expected you'd need LD_LIBRARY_PATH. that's #22335

That popcount thing looks super bogus. On my linux box that's calling ::AK::popcount from AK/BuiltinWrappers.h, which we using into the global namespace. it shouldn't be calling ::popcount from /usr/include/strings.h.

0-wiz-0 · 2024-02-27T18:43:15Z

Thanks, I'll use AK_OS_NETBSD.
pkgsrc doesn't like temporary RPATHs. only the final installation RPATH is allowed. So the LD_LIBRARY_PATH workaround is fine.
Does Linux even provide a native popcount? NetBSD does, perhaps that's the problem.

I needed no further patches to compile; I had to change the font search path (pkgsrc uses ${PREFIX}/share/fonts which is usually, but not always,/usr/pkg/share/fonts).

On startup, I have a major problem though:

MAP_FAILED calls to mind mmap() - I should perhaps mention that NetBSD by default doesn't allow mapping writable mmap sections as executable (PAX mprotect), which annoys most JITs. The workaround is to double-map sections; the NetBSD mremap man page has example code for this.

However, turning this feature off didn't fix the problem, so perhaps that's a red herring. Any ideas?

ADKaster · 2024-02-27T18:46:59Z

That mmap should be just a

mmap(nullptr, HeapBlock::block_size, PROT_READ | PROT_WRITE, MAP_ANONYMOUS | MAP_PRIVATE, 0, 0);

where HeapBlock::block_size is 4096.

serenity/Userland/Libraries/LibJS/Heap/BlockAllocator.cpp

Line 58 in a0dc958

    
           auto* block = (HeapBlock*)mmap(nullptr, HeapBlock::block_size, PROT_READ | PROT_WRITE, MAP_ANONYMOUS | MAP_PRIVATE, 0, 0);

perhaps NetBSD expects that the fd parameter is -1 for MAP_ANONYMOUS?

0-wiz-0 · 2024-02-27T18:48:27Z

I think you're right, from NetBSD's mmap man page:

           MAP_ANON              Map anonymous memory not associated with any
                                 specific file.  The file descriptor is not
                                 used for creating MAP_ANON regions, and must
                                 be specified as -1.  The mapped memory will
                                 be zero filled.

           MAP_ANONYMOUS         Synonymous with MAP_ANON.

about:srcdoc is a known issue #23216

hitting issues in getaddrinfo/freeaddrinfo is unexpected though.

It looks like we copy struct addrinfo into a vector from getaddrinfo, and then free the pointer we got from getaddrinfo with freeaddrinfo later.

C++ is not my forte, but from a short review this looks fine.
I assume:

        TRY(addresses.try_append(*result));

makes a copy of the result and doesn't move it?

What is a site that should definitely work (for testing)?

clausecker · 2024-05-05T13:52:07Z

The same patch to mmap with MAP_ANONYMOUS is also needed to make Ladybird work on FreeBSD (again). I'll include it as a distribution patch into the port.

So I tried ladybird with the proposed patches from the pull request, the one in the comment #23375 (comment) and the last one from comment #23375 (comment) (constexpr) on NetBSD, and it starts up and shows the search bar with some icons for Bing, Duckduckgo etc. but does nothing when I click on them and core dumps when I enter "https://github.com/" in the URL bar. Only one core dump though, for RequestServer.

ADKaster · 2024-05-09T19:17:32Z

Sounds like the problem with getaddrinfo is still there. Still not sure what we're doing wrong with those, though I haven't looked into it very much.

Still core dumps, a problem in getaddrinfo, see SerenityOS/serenity#23375

That's when I try to visit https://github.com

0-wiz-0 · 2024-06-06T20:39:48Z

I saw the commit and thought I'd give it another try. Most patches seem merged, so I just removed all local changes.
Compilation currently fails with multiple instances of:

That's with gcc 10.5.0 in case it matters.

ADKaster · 2024-06-06T20:45:30Z

We bumped our minimum required gcc version to 13.x recently 😅 . That or clang-17+

0-wiz-0 · 2024-06-06T21:03:02Z

Ah, I forgot that the package was already using gcc 12. I've now switched it to gcc 13, and see:

NetBSD has its own popcount: https://man.netbsd.org/popcount.3
Can you please rename ladybird's one or make it compatible?

ADKaster · 2024-06-06T21:13:28Z

Ah hmm. Does qualifying that call as AK::popcount fix the build error?

0-wiz-0 · 2024-06-06T21:27:09Z

That does indeed work! Thanks:

Compared to last time I built this, liblagom-gui.so is not installed any longer. Just mentioning this to check if this is intended or a local issue.

Also, progress! I visited github.com again and it showed the page! :)
While I was scrolling down, ladybird died though :(
