[Bug] GHDL-LS crashes with some projects on Windows

[pidgeon777]

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

Something seems to have caused an exception related to the files_map.adb GHDL-LS file, line 608.

[pidgeon777]

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:

[tgingold]

I barely use windows, so I have to create a setup to reproduce the issue.

[pidgeon777]

I'm willing to help with the testing.

[tgingold]

Ok. The first thing to do is to reproduce the bug with logs enabled in ghdl-lsp. You need to run ghdl-lsp with two '-v'. The log file would contain more details.

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)...

[tgingold]

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.
