When I use GHDL-LS with Neovim, if I open a source file not defined in the list of project files, GHDL-LS keep running, but as soon as I open a source file belonging to the list specified in the hdl-prj.json file, it crashes.

OS: Windows 10 x64 Pro
ghdl-ls: ghdl-ls 2.0.0-dev

hdl-prj.json:

An update: when specifying the full source file path in the hdl-prj.json file, going from this:

....
    "files": [
        { "file": "ENTITY_TOP.vhd", "language": "vhdl" }
    ] 
....

to this:

....
    "files": [
        { "file": "C:/Work/MEGA/Portable/GHDL/bin/src_test/ENTITY_TOP.vhd", "language": "vhdl" }
    ] 
....

then GHDL-LS doesn't crash anymore when opening that file, but it reports as warning:

entity "entity_top" was also defined in file "C:/Work/MEGA/Portable/GHDL/bin/src_test/ENTITY_TOP.vhd"

In conclusion, in my opinion, there are some serious bugs in the way file paths are managed by GHDL-LS on Windows.

For example, when opening the source file with the entity definition of ENTITY_TOP, even if this file is also added to hdl-prj.json, it gets analysed but it is reported as if that very same file is not considered as belonging to the project.

So, we have to investigate the way file paths are handled by GHDL-LS on Windows, and this should be a good start to fix the issue.

@pidgeon777, how are you installing GHDL, ghdl-ls and the Neovim client on WIndows?

For installing ghdl-ls, I followed those advices:

More in detail, these are all of the tests I did. In each of those, opening ENTITY_TOP.vhd file was the only thing done, and nothing else.

Setup A

hdl-prj.json:

{
    "options": {
        "ghdl_analysis": [
            "--workdir=work",
            "--ieee=synopsys",

            "--warn-unused",
            "--warn-others",
            "--warn-pure",
            "--warn-static"
        ]
    },
    "files": [
        { "file": "C:/Work/MEGA/Portable/GHDL/bin/src_test/ENTITY_TOP.vhd", "language": "vhdl" },
        { "file": "C:/Work/MEGA/Portable/GHDL/bin/src_test/ENTITY_TOP_2.vhd", "language": "vhdl" },

        { "file": "C:/Work/MEGA/Portable/GHDL/bin/src_test/Sub/ENTITY_1.vhd", "language": "vhdl" },
        { "file": "C:/Work/MEGA/Portable/GHDL/bin/src_test/Sub/ENTITY_2.vhd", "language": "vhdl" }
    ]

GHDL-LS crashed because the vhdl-ls.trace.in.5 and vhdl-ls.trace.out.5 files already existed, according to the log above.

This should be classified as a bug I think (it can append 1 to 5 to the trace file names, but not beyond, resulting in a crash).

Anyway, after having deleted those files and restarted the test, we obtain:

vhdl-ls.log:

The third row of vhdl-ls.trace.out is:

{"jsonrpc":"2.0","method":"textDocument/publishDiagnostics","params":{"uri":"file:///C:/Work/MEGA/Portable/GHDL/bin/src_test/ENTITY_TOP.vhd","diagnostics":[{"source":"ghdl","range":{"start":{"line":0,"character":0},"end":{"line":0,"character":0}},"message":"entity \"entity_top\" was also defined in file \"C:/Work/MEGA/Portable/GHDL/bin/src_test/ENTITY_TOP.vhd\"","severity":2},{"source":"ghdl","range":{"start":{"line":84,"character":2},"end":{"line":84,"character":2}},"message":"infinite loop for this process without a wait statement","severity":2}]}}Content-Length: 38

This is a bug because the full path of ENTITY_TOP.vhd is defined in hdl-prj.json file, but when opening it, it is detected by GHDL-LS as not belonging to the project files, instead.

What I mean is that, if a file listed in hdl-prj.json is opened, GHDL-LS should not detect and report it as if didn't belong to the project.

In my opinion, this is due to the way GHDL-LS handles Windows paths, but I'm not sure about this.

Setup B

Here I only changed the paths of the source files, going from absolute to relative (to the location of hdl-prj.json file).

hdl-prj.json:

{
    "options": {
        "ghdl_analysis": [
            "--workdir=work",
            "--ieee=synopsys",

            "--warn-default-binding",
            "--warn-binding",
            "--warn-reserved",
            "--warn-nested-comment",
            "--warn-parenthesis",
            "--warn-vital-generic",

            "--warn-pure",
            "--warn-static"
        ]
    },
    "files": [

In the log file above, this line is reported:

[ ERROR ] 2021-06-30T09:43:53+0200 ] ...A\Portable\Neovim\share\nvim\runtime\lua\vim\lsp\rpc.lua:457 ]	"rpc"	"ghdl-ls"	"stderr"	"YSTEM.ASSERTIONS.ASSERT_FAILURE : files_map.adb:608\n"

This time GHDL-LS crashed, maybe path management could be involved in this.

Summary:

When opening ENTITY_TOP.vhd, this happens:

  • Setup A: no GHDL-LS crash, but files are not currently identified as belonging to the project.
  • Setup B: GHDL-LS crashes.

Also, in Setup B, if a file not listed in hdl-prj.json file is opened, GHDL-LS correctly reports it as not belonging to the project files, but if a file listed in hdl-prj.json is opened instead, then it crashes as described.

Finally, there seems to be a bug about vhdl-ls.trace.in.XXX and vhdl-ls.trace.out.XXX file generation (output file writer set XXX to 5 as a maximum, then GHDL-LS crashes).

I have tried to install neovim on my windows VM. Big failure: I cannot install nvim-lspconfig plugin.
I think vim-plug is installed, but it simply doesn't work. As far as I understand, it is supposed to use git, but I am not sure how git is invoked (and not even sure how git should be installed)...

I am making some progresses.

I would suggest making use of this config:

https://github.com/ChristianChiarulli/LunarVim

It already provides many useful plugins, and also it simplifies the process of enabling GHDL-LS in Neovim.

I can provide support if needed.

I also add that Neovim 0.5 stable has just been released after 3 years of development, 0.4.4 is now its previous version.

I was not able to reproduce the issue, but I am using the python from mingw. From the log, I would assume you are using a full windows python. Is that correct ?

@tgingold with latest change how pyGHDL sets the DLL search path for Python 3.8/3.9, you should be able to run also ghdl-ls from Windows CPython. You can call the libghdl...dll within MinGW64 by using GHDL_PREFIX.

For installing GHDL-LS, I followed those advices:

#73 (comment)

I was not able to reproduce the issue, but I am using the python from mingw. From the log, I would assume you are using a full windows python. Is that correct ?

I can confirm that this is the command used to launch GHDL-LS in Neovim:

C:\msys64\mingw64\bin\ghdl-ls.exe --verbose --verbose --log-file vhdl-ls.log --trace-file vhdl-ls.trace

This command, in turn, launches:

C:\msys64\mingw64\bin\python.exe "C:\msys64\mingw64\bin\ghdl-ls-script.py" "--verbose" "--verbose" "--log-file" "vhdl-ls.log" "--trace-file" "vhdl-ls.trace"

Ok, I can reproduce a crash.

There is a consistency issue with the colon in uri like 'file:///C:/xxx'
It can be encoded as '%3A'

On my setup, my last commit fixes the issue. Now, does it work on your setup ?

I have two questions, these are the commands I executed for installing GHDL-LS into Windows.

In MSYS2 shell:

$ pacman -Syu

$ pacman -S mingw-w64-x86_64-ghdl-llvm
$ pacman -S mingw-w64-x86_64-python-pip

$ pacman -S git

In MinGW64 shell:

pip install git+https://github.com/ghdl/ghdl.git

I would like to ask:

  1. What procedure did you follow to install GHDL-LS in Windows on your setup?
  2. How could I update my local installation so that I can try your new version?

Thank you

file:///C:/ is not a valid URL for (local) resources.

The format is <protocol>://<host/<path>. For Windows, a C: drive translates to /c/, because <host> is usually not used, hence the 3 forward slashes in a URL for paths compare to 2 slashes in e.g. https://.

@umarcor should know how to get the latest binaries (and if this is possible).

You can also simply do a new pip install on the git repo. The binaries haven't changed.

For my setup, I always have a cloned repo and I build locally.
