Using sourcekit-lsp on Ubuntu 18.10

cukr · April 3, 2019, 7:24pm

Is there a way to use sourcekit-lsp on Ubuntu 18.10? sourcekit-lsp install instructions want me to point it to a toolchain, but swift.org provides toolchains only for macos, old ubuntu and even older ubuntu. I can build swift from source, but what do I set SOURCEKIT_TOOLCHAIN_PATH to?

I would expect the 18.04 toolchain to work on 18.10 as well, so please give that a try and let us know if you run into issues. + @mishal_shah in case he knows of any issues on 18.10.

Unfortunately it cannot find libtinfo.so.5

swift: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

It looks like there is a libtinfo5 package for 18.10 that should contain that library; does installing that fix it? On 18.04 that libtinfo5 would be pulled in by our dependency on libncurses5-dev.

cukr · April 4, 2019, 6:05pm

Oh god. Such an easy fix. I swear I tried to find out what package provides it, and couldn't find it. Thank you very much! <3
After installing libtinfo5 and libncurses5 (not libncurses5-dev) it starts up from the toolchain!
The only problem is that I get [SR-8690] swift REPL error: adding range [0x1464a-0x146ba) which has a base that is less than the function's low PC · Issue #4488 · apple/llvm-project · GitHub , but apparently I can just ignore it.

Next step - trying lsp!

Unfortunately I got stuck again - this time while building sourcekit-lsp. Unfortunately there's even no error message, unless you count a single dot as one :(

@Aciid is this a known issue with the output of swift-build on Linux? Any suggestions?

Aciid · April 4, 2019, 7:23pm

No, this is the first I've seen something like this. Maybe try with -v.

cukr · April 4, 2019, 7:53pm

The dot wasn't the whole error message! Every time I run the command, the error gets cut out in a different place!

The path I provided was wrong - it has to be absolute, without the ~ :/ After I changed it - it compiles.

Thank you everyone for help! It works now! (As long as I create a new package. Somehow the sourcekit-lsp crashes when I open an old package, that I edited with LSP in the past. (deleting the .build directory fixed that package))

If you can reproduce this crash, it would be great to file a bug at bugs.swift.org and attach the code + .build directory content.

cukr · April 4, 2019, 9:55pm

My celebration was premature. It crashes for new packages too. If I do:

swift package init --type executable
swift run
ctrl+k ctrl+o and then select that directory in Visual Studio Code
it prints this:

[Info  - 11:42:00 PM] Connection to server got closed. Server will restart.
[Info  - 11:42:00 PM] Connection to server got closed. Server will restart.
[Info  - 11:42:01 PM] Connection to server got closed. Server will restart.
[Info  - 11:42:01 PM] Connection to server got closed. Server will restart.
[Error - 11:42:01 PM] Connection to server got closed. Server will not be restarted.

If I open the directory in VSC first, and then build it everything works perfectly (until I close VSC)

I tried to attach debugger to the server (as described here), but lldb errors out too

cukier@papryka:~/Desktop/lsp/foo$ lldb -w -n sourcekit-lsp
(lldb) process attach --name "sourcekit-lsp" --waitfor
error: attach failed: lost connection
(lldb)

Attaching a debugger to the extension (as described here) and setting a breakpoint at all exceptions shows "Error: Cannot find module 'supports-color'" being thrown, but I'm not sure how relevant that is.

blangmuir · April 4, 2019, 11:55pm

Is that the full output from the console if you select "OUTPUT > SourceKit Language Server"? If you turn on tracing (Settings > sourcekit-lsp > Trace), do you get any additional information?

cukr · April 5, 2019, 5:09am

Yes

blangmuir · April 5, 2019, 5:54pm

I can reproduce a crash, but I'm not sure if it's the same one you're seeing because I get different output. Could you please try to get a backtrace from sourcekit-lsp? Here's what I did:

$ code path/to/project
## Ensure no .swift files are open so that sourcekit-lsp hasn't launched yet

$ sudo lldb # you may not need sudo, but I did in order to attach

## Open a .swift file and then quickly:
(lldb) process attach -n sourcekit-lsp
Process 3718 stopped

(lldb) continue
## Crash

(lldb) bt

Also, we should move this to a bug report on bugs.swift.org. If you're able to attach the project you're using, please do - that might also be important.

If package was never built, or I delete the .build directory, the language server works perfectly. Steps to reproduce: ``` java $mkdir bug_report_package $cd bug_report_package $swift package init --type executable $swift run $code . click on main.swift file in VSC ``` More info about how I got here is in this thread: <https://forums.swift.org/t/using-sourcekit-lsp-on-ubuntu-18-10/22598> lldb output: ``` java cukier@papryka:~$ sudo /home/cukier/Developer/swift-5.0-RELEASE-ubuntu18.04/usr/bin/lldb (lldb) process attach -n sourcekit-lsp Process 10513 stopped * thread #1, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c0e6a3f6 libc.so.6`__GI___sigsuspend(set=0x00007f30c1b5b950) at sigsuspend.c:26:10 thread #2, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfa142 libpthread.so.0`do_futex_wait at futex-internal.h:205:13 thread #3, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfa142 libpthread.so.0`do_futex_wait at futex-internal.h:205:13 thread #4, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfa142 libpthread.so.0`do_futex_wait at futex-internal.h:205:13 thread #5, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfa142 libpthread.so.0`do_futex_wait at futex-internal.h:205:13 thread #6, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfa142 libpthread.so.0`do_futex_wait at futex-internal.h:205:13 thread #7, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfa142 libpthread.so.0`do_futex_wait at futex-internal.h:205:13 thread #8, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfa142 libpthread.so.0`do_futex_wait at futex-internal.h:205:13 thread #9, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c0f4410f libc.so.6`epoll_wait(epfd=3, events=0x00007f30b1ffaa30, maxevents=16, timeout=-1) at epoll_wait.c:30:10 thread #10, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bf72eb libpthread.so.0`__pthread_cond_wait at futex-internal.h:88:13 thread #11, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfa142 libpthread.so.0`do_futex_wait at futex-internal.h:205:13 thread #12, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfac24 libpthread.so.0`__libc_read at read.c:26:10 thread #13, name = 'sourcekit-lsp', stop reason = signal SIGSTOP frame #0: 0x00007f30c2bfac24 libpthread.so.0`__libc_read at read.c:26:10 Target 0: (sourcekit-lsp) stopped.

Any updates on this? Been having the exact same problem with swift 5.1 and Ubuntu 18.04

cukr · June 20, 2019, 10:26am

LSP doesn't crash for me anymore. I'm not sure when it fixed itself.
I checked swift-5.1-DEVELOPMENT-SNAPSHOT-2019-05-29-a-ubuntu18.04 toolchain on Ubuntu 19.04

atyshka · June 20, 2019, 11:45am

Hmm... That’s exactly the same tool chain I am using. What sourcekit Version are you using? The latest on master or the release tagged for 5.1 (5/29)? I am using the tagged release

cukr · June 20, 2019, 12:02pm

I was on something close to the current master. I checked out commit 76ee75da08bc2ab9a50d6049dd08fb3f9dc5d51f (I think that's the one you're using) and it's broken for me too.
