Crash when changing directory in custom build system

[MK-Alias]

OmniSharp: v1.9.7
Windows: 10 (BUILD: 1803)
Sublime: 3.1.1 (BUILD: 3176)

After a short period (couple of minutes) OmniSharp stops working. It states in the status bar:

OmniSharp: Error Talking to http://localhost:50736/autocomplete

This shows up in the console:

HTTPConnectionPool(host='localhost', port=50736): Max retries exceeded with url: /autocomplete (Caused by ProtocolError('Connection aborted.', ConnectionRefusedError(10061, 'No connection could be made because the target machine actively refused it', None, 10061)))

If I would direct my browser to http://localhost:<port> when OmniSharp is still working, then a blank page shows. After the error I get: ERR_CONNECTION_REFUSED

So it seems that Node is having problems? Or, also i've noticed that the previous version send some kind of keep alive messages... This version does not! Perhaps just a timeout?

[Rosalie241]

Odd, can you see if the console shows something else?

I did not change the way omnisharp-sublime interacts with omnisharp-roslyn.

On my end part of the problem seems to be my buildsystem. Every time a do a build the .csproj gets overwritten. Sublime OmniSharp seems to not handle this correctly. (VScode version does not care)

I will try and investigate if not overwriting the .csproj file solves this.

I've removed all data, paths and names of the console output but notice this:

@virella2385 verify that you have all the requirements installed

@ALIAS-777 odd, can you try to manually execute omnisharp.cmd -s /path/to/solution/directory
in OmniSharp/prebuilt-omnisharp-roslyn/ ?
then just do the same thing(overwriting the csproj) and see if the same thing happens

[MK-Alias]

Found the culprit... It's really the weirdest thing. After doing lots of test and finding out the running my build from outside Sublime worked just fine and keeps OmniSharp going, I've tested an other scenario. My build system uses cd and popd a lot and that's the problem. If you change directory in a Sublime build system then the problem occurs - omnisharp plugin reacts to this. Here is repro.

test.cmd: Put this in the root of the folder you are opening.

@echo off
echo Going to CD
cd ..

MyBuild.sublime-build: Put this in <ST3_userdir>\Sublime Text 3\Packages\User

{
	"working_dir": "$folder",
	"cmd": ["test.cmd"],
	"shell": true
}

Set MyBuild as default build system by checking it on in: Tools -> Build System -> MyBuild ... And then execute the build: Tools -> Build

This will crash OmniSharp. For now I will just workaround this by building from a console or AutoHokeys Script until this gets fixed.

Thank you for figuring it out! I'll research the code and see if it's the fault of this plugin or sublime. Thank you very much! :)

@ALIAS-777 I looked at it, doesn't seem like something I can fix sadly

omnisharp-sublime/lib/helpers.py

Lines 34 to 58 in 6adda05

	def current_solution_filepath_or_project_rootpath(view):
	project_file = project_file_name(view)
	if project_file is not None:
	print('project file %s found' % project_file)
	data = project_data(view)
	if 'solution_file' not in data:
	raise ValueError('Please specify a path to the solution file in your sublime-project file or delete it')
	project_dir = os.path.dirname(project_file)
	solution_file_name = data['solution_file']
	solution_file_path = os.path.join(project_dir, solution_file_name)
	return os.path.abspath(solution_file_path)
	else:
	active_window = sublime.active_window()
	if len(active_window.folders()) > 0:
	return active_window.folders()[
	0] # assume parent folder is opened that contains all project folders eg/Web,ClassLib,Tests
	try:
	return os.path.dirname(active_window.active_view().file_name())
	except Exception:
	print("New file not saved. Can't find path.")
	return None

@tim241 I'm not familair with python nor the internals of the sublime plugin system, but can you not just query the path the first time the function is called and store it in a variable instead of re-querying it on each call.... Does that fix it? (or perhaps in an init function?). Or is there maybe an hook (callback) when a new "project folder" opens? Then query it there and then store it.

These are obviously not the most prettiest ways of doing it. but the only things changing the working directory seem to be build-systems anyways.

To be honest, in my opinion sublime+omnisharp is not a great combination at this point. I'ts just unstable and frustrating to use. I will check it out in the future, perhaps things are better then. For now I will stick with VScode. (which Omnisharp impenmentation is very decent)

Thanks for all your help though!

Any solution for this already? I'm having the same problem, I 'm trying to use Sublime Text 3 with Unity, I followed this tutorial: http://makegamessa.com/discussion/2879/tutorial-using-sublime-text-3-in-unity-with-intellisense-autocomplete and I'm getting this error on console:

Error description is in portuguese but it means exactly the same thing.
I know the tutorial is quite old but I didn't found anything as easilly explained, could anyone help plz?

I'm running into same problem. Trying to use OmniSharp with Sublime for Unity, getting connection refused.
