Hello,
For some reason, I notice that clangd isn't picking compilation commands from the compilation database in one instance. The debug log is appended below. I have the compilation_database_folder set in .ycm_extra_conf.py the following way:
compilation_database_folder = '../build.release'
and the build.release does have a 'compile_commands.json' with the command to compile the said file (which I can verify separately as well). However, ycm isn't picking it. The error log doesn't have anything other than INFO messages. Is there something else to check to see what's going wrong? In fact, I can confirm that the behavior is the same as having a non-existent database folder.

If you're using clangd, you don't need an extra conf file and usually it actually suppresses some functionality. I would recommend removing it and either:
- Use `g:ycm_clangd_args` to add `--compile-commands-dir=<path to where your compile commands are>`, or
- symlink the compile_commands.json to the root of your project (usually easier)
For the actual question, we can't really come up with any theories without seeing your actual .ycm_extra_conf.py file and e.g. which file is problematic.

Thank you, but I use clangd for multiple projects and a single configuration in .vimrc won't work. But the second option you suggest would be good. But with this second option, I have issues with getting clangd started. Even after restarting the server, it yields:

For the actual question, we can't really come up with any theories without seeing your actual .ycm_extra_conf.py file and e.g. which file is problematic.
Thanks - I actually figured this out. I was using the default .ycm_extra_conf.py from a previous Ycm, and there was the FlagsForFile def that needed to be updated as below. Incidentally, I had contributed a patch to update the default .ycm_extra_conf.py that was committed upstream some time back but I had this old version still for this project - but there wasn't an error that pointed to it. It was a silent incorrect behavior.
def GetCompilationInfoForFile( filename ): -> def Settings( **kwargs ):
-> filename -> kwargs[ 'filename' ] )
It now works fine with this change, but it'll be good to also figure out why the symlinking to compiler_commands.json from the working dir doesn't help.
Thanks,
- Uday

Need to see the clangd log to see why it is failing to start. You can get is from YcmToggleLogs

Try rm -rf .clangd then restart Vim
That fixes about 99% of index crashes

I did this and restarted vim, but have the same issue. Restarted ycm server as well, but the issue persists. The logs show a similar stack trace but on a different file. Not sure why this doesn't happen with the .ycm_extra_conf.py approach (I'm using the default configuration that ships with ycm except that I'm setting the compilation database folder).

Oh dear. I guess you’d need to report this to clangd devs as clangd is crashing while trying to index your project.
You could also try the latest snapshot build from https://github.com/clangd/clangd (set g:ycm_clangd_binary_path to point at it)

Thanks, I'll do that. But why does it when using the ycm extra conf?
It turns out the project it is indexing is the thing clangd itself depends on - LLVM (one of its in-tree sub-projects).

Becuase clangd never sees your compile db, so this stops it from doing a full background index

Thanks - it now works with the trunk version of clangd. It is indexing everything.

Thanks. I now realize that clangd would have the compiler_commands.json in that dir - I was thinking that ycm was somehow providing the compiler_commands.json it knows about (via its ycm_extra_conf) to clangd.
