VSCode Perl::LanguageServer causes a process that consumes CPU #200

Open adefaria opened 1 year ago

adefaria commented 1 year ago

When running Perl::LanguageServer inside of VSCode there is a master perl that consumes about 100% of a CPU. Initially, this process fires off a number of pls processes, apparently parsing all of the Perl modules it can find and communicating that data to the master perl process bloating it up to 1.5G in my case. OK, I understand that. There's a lot of Perl code here. However, after it settles down and the pls processes go away the master perl process continues to chew on about 100% of one CPU, even if VSCode is essentially idle.

Closing VSCode causes the master perl process to go away.

An strace of the master perl reveals:

select(16, [3 5 8], [], NULL, {tv_sec=3600, tv_usec=0}) = 1 (in [5], left {tv_sec=3599, tv_usec=999999})
select(16, [3 5 8], [], NULL, {tv_sec=3600, tv_usec=0}) = 1 (in [5], left {tv_sec=3599, tv_usec=999999})
select(16, [3 5 8], [], NULL, {tv_sec=3600, tv_usec=0}) = 1 (in [5], left {tv_sec=3599, tv_usec=999999})
select(16, [3 5 8], [], NULL, {tv_sec=3600, tv_usec=0}) = 1 (in [5], left {tv_sec=3599, tv_usec=999999})
select(16, [3 5 8], [], NULL, {tv_sec=3600, tv_usec=0}) = 1 (in [5], left {tv_sec=3599, tv_usec=999999})

over and over again.

Could you set the log-level to 2 and look in the Perl-LanguageServer output pane of vscode if there is anything going on? Please post the output here.

adefaria commented 12 months ago

BTW, as I said various pls processes start and apparently parse all .pl and .pm files found in the current directory. This bloats the perl process significantly. Is there a way to configure it such that certain directory trees are ignored? For example, we use a specific version of Perl that is contained in a directory called 3rdparty. I don't want to debug that stuff but would like to exclude it from this process.

Here's the log:

For now, I have turned it off pls by removing the execute bit. The problem is that over time it eventually consumes all of my memory causing my sandbox to hand which is not conducive to productivity. I'm not sure what else to do or what else to supply.

richterger commented 11 months ago

This is the log of remotessh. Could you please switch the output to Perl LanguageServer and resend the output

adefaria commented 11 months ago

Sorry. Never knew that the Output tab had things to switch to but that makes sense. Ok, after restarting vscode and letting it parse the initial files until it settled down to just one Perl process taking 99.3% of the CPU, the Output tab for Perl Language Server contains:

Version of IDE/Editor plugin is 2.6.1
Version of Perl::LanguageServer is 2.3.0

Before we continue, could you please update Perl::LanguageServer to the newest version from CPAN (2.6.1). Just running cpan Perl::LanguageServer normaly should do the upgrade. If this doesn't change anything, please in preferences for Perl::LanguageServer set the LogLevel to 2 and then repost the output.

adefaria commented 11 months ago

OK, I verified I have the correct versions. Seems I had two PLS extensions in the IDE. One from you:

2023-12-22@09:01:41

and one from FractalBoy:

2023-12-22@08:59:53

I disabled FractalBoy's, set logLevel to 2 for your extensionand restarted. I also saw this in your extension settings and removed Path Map:

2023-12-22@09:04:42

I've attached the log file Perl-LanguageServer.log

richterger commented 11 months ago

The log look fine. I stumbled about the sentence "For now, I have turned it off pls by removing the execute bit". pls is not part of Perl::LangaugeServer. So maybe it's from the other extention. Did the CPU go down, when disabling the other extention? If not, please press c inside of top so we see the full command line of the process taking up 100% cpu

adefaria commented 11 months ago

I do see a lot of pls processes running when I first start vscode. I assumed they were forked off by the perl process that later chewed up the CPU. I thought they were contributing to the problem. I've enabled the execute bit on pls.

The other extension has been removed. The CPU usage does not go down. Here's the full command line of the perl process:

/usr/local/cpanel/3rdparty/bin/perl -I/opt/clearscm/lib -MPerl::LanguageServer -e Perl::LanguageServer::run -- --port 13603 --log-level 0 --log-file  --version 2.6.2

This is still an issue for me...
