code completion gives me a IOException: pipe closed

[jcompagner]

if i look at the stack below:

it almost seems this is a logging thing?
(i did have some log enabled but only to the console not to a file)

i turned of the logs completely to see if i also get it then.
i do get a lot of logs in my normal eclipse workspace log file (that generates a lot of bak_X.log files besides the normal log files
also with a lot of other exceptions coming from lsp4e or lsp4j

[mickaelistria]

What files are you editing when you see this error? Such error usually happens when the language server is shutdown for whatever reason (eg a server side error aborting execution)

[jcompagner]

always ts files (but angular ts files)
most of the time this is fixed by reopening the file (but that doesn't mean that the language sever is also restarted, because i could have had other in open editors files just fine).
Somehow it would be nice if the system auto corrects itself (so a reconnect is tried?)

[mickaelistria]

A reconnect is tried. But a LS being erroneous and shutting down is not really something we can mitigate properly on client side anyway.

[mickaelistria]

I've moved it to Wild Web Developer as the issue is most likely on the server or integration side, not in generic LS support.

[jcompagner]

i just got it again (so its not related to logging)
and i was just coding in that file the whole morning (so lets say 5 minutes before this it worked fine)

now the stack is also a bit different:

the only way to fix this is to close and reopen the same editor
But as far as i know the language server is not stopped or restarted because of this (there are other editors open for the same project)

[mickaelistria]

It looks like the Language Server crashes here. Is this a particular code construct triggering this error? Or it it somehow crashing that way every ~5 minutes (so it could be some memory issue).

But as far as i know the language server is not stopped or restarted because of this (there are other editors open for the same project)

This error really makes that the Language Server is restarted. If you want to verify that, check the PID of the node .... typescript-language-server/... process before and after a crash, it will most likely be a different one.

[jcompagner]

its not that it crashes after every 5 minutes. My comment about the 5 minutes that it worked fine before and suddenly i get this
I will try to see if the typescript server is really a different process suddenly
if i log the typescript language server only i also should see this right?

[mickaelistria]

if i log the typescript language server only i also should see this right?

The Language Server logs you see in preferences are logging the Language Server messages, they're not triggering or capturing internal logging of the server. So I don't think those would help much unfortunately.

ah so there are no "start" messages? (i think with the angular lang server i do see that i can see when it started up)

[mickaelistria]

Language Server can use some operations to trigger some logging or alert in the client, but this is more intended to user assistance, not to debugging.

[jcompagner]

there is no change in the Language Servers when it happens
so i had a script editor open again and i got that broken pipe again
i made a screen dump of the taskmanager

then i closed the editor, reopen it again
and nothing changed compared to the nodes that are started.. but the code completion works again
Now i will have a look if i get it again if then maybe something is changed..

Should we move this case to LSP4J ?

Because no matter what happens (if something really crashes) it should just auto correct itself right?

[jcompagner]

what i do notice that it is just code completion that bombs out (and maybe also validation)
because document hover or go to declaration (F3) is just working fine.

[mickaelistria]

Maybe the language server crashes on completion with an internal error for some cases. Can you please provide a minimal project and steps to reproduce?

[jcompagner]

hmm with the latest release 20220613 on my main product i can't do anything anymore, it always bombs out all the time.
constantly getting that stream closed and the logging of the languages services don't tell anything usefull

in the eclipse workspace log file i see:

and yes also constantly that starting up? so it seems that it constantly crashes for some reason and it wants to restart?

The thing is, opening that same directory in visual studio code has no problems, everything works nicely.
