remotePathResolve not working on VS Code Windows with a coverage.xml file using Unix paths about vscode-coverage-gutters

[denisrossetre]

Actually, I solved the problem! The thing is that the path parsing will be done on a Unix path in a Windows system.

By changing the value
"coverage-gutters.remotePathResolve": ["/opt/local", "c:/Users/myusername/projects/myprojectname"]
to
"coverage-gutters.remotePathResolve": ["\\opt\\local", "."]
the problem disappeared (the second value "." does not matter so much, but I prefer relative paths for the local dev system as they are more stable).

To close this issue, I'd like to write a bit of documentation for the remotePathResolve setting. Would you accept a PR, and if so, where should I put the documentation?

@denisrossetre Thanks for the ticket! Are you able to grab more logs from the extension output log area?

In terms of extra logging, check out this area, and you could maybe remove the .size to print the whole cache and that would assist us in figuring out what is inside (this should really be an extension setting to enable "verbose" logging mode but sadly haven't got to that yet 😓).

vscode-coverage-gutters/src/coverage-system/coverageservice.ts

Lines 101 to 105 in c15ac1a

	const dataCoverage = await this.coverageParser.filesToSections(dataFiles);
	this.outputChannel.appendLine(
	`[${Date.now()}][coverageservice]: Caching ${dataCoverage.size} coverage(s)`,
	);
	this.cache = dataCoverage;

I am glad you got it figured out 👍🏻 !
More documentation is always welcome, so PR will definitely be accepted, thanks.

I think the tips and tricks section would be a good fit? It gets great SEO from being on the front page + in the marketplace.

@denisrossetre I'm encountering the same issue that you were -- I'm using Windows 10, and I have a docker container running Linux, but coverage gutters isn't showing the code coverage in VSC.

I tried using your fix, here is my settings.json

"coverage-gutters.coverageFileNames": [
        "coverage.xml",
        "lcov.info",
        "cov.xml",
        "jacoco.xml"
    ],
    "coverage-gutters.remotePathResolve": [
        
        [
            "\\home\\dev\\Mxxxx",
            "."
        ]
    ]

The /home/dev/M... path is what I'm using in the container.

In the CG log I see this:

[1698181260483][coverageservice]: c:\Users\Exxxxxxxx\gitlab\Mxxxx\coverage.xml
[1698181260483][coverageservice]: Loaded 1 data file(s)
[1698181260488][coverageservice]: Caching 6 coverage(s)

[1698181260488][coverageservice]: RENDERING
[1698181260488][coverageservice]: READY

so I know that it's picking up my coverage file, but there's just still no visual indication on the file, and the bottom bar still shows "No coverage".

Did you end up having to do anything else other than changing this setting, to fix the issue? I'm running Coverage Gutters v2.11.0

@ralittl Hmm I think you might want to try one level of array instead?
"coverage-gutters.remotePathResolve": ["\\home\\dev\\Mxxxx", "."]

Also, once you get the system working, try out the watch button in the bottom status bar and you should get an output similar to the following:
