Cpu load, memory leak

[pakulin]

mac sierra
Code 1.15.1
Php instellisense 1.15.0
php 7.1.6_18

Cpu load 95% with no tabs opened, memory usage gradually increased by 1-2 mb in 10 secs
Maybe this will help:

I also see a PHP process start and utilize a full core of my CPU as soon as I open VSCode.

OSX 10.12.5
VSCode 1.15.1
PHP Intellisense 1.5.1

EDIT: Err, it seems to be gone now. I saw it running for a while last night, maybe it just took a while to scan my current project? It is rather large.

What is the bug here? The language server needs to build it's index the first time when it's not cached, it's expected that this takes some CPU and RAM

[alancd]

It looks like there's no caching, and every time you open a project with VS CODE, a parsing process is opened.

[felixfbecker]

dependencies are cached

+1 i have the same problem. Everytime i relaunch Vscode, parsing starts from begining and dependencies are not cached - it may be because i have 2 separate folders and each of them has one composer.lock file.
Also i have large php projects where i don't use composer so all files are parsed on start. It would be nice to manually specify which files should be cached.

I'm seeing this too, even when launching simple projects.

[felixfbecker]

Could you try setting COMPOSER_ALLOW_XDEBUG=1 with XDebug on, then see if the language server crashes with a max recursion limit reached error?

[phil-nelson]

I have found a bug with the recent foreach handling, this is a case that causes an infinite loop:

$a = [];
foreach ($a as $k => $a) {
}

I have a fix but it's not very nice yet, working on it.

@jens1o you say the project you're seeing this on is simple, can you confirm if you have something like the above?

Another example is

foreach ($a->getArray() as $k => $a) {
}

Edit: to be clear, the issue I'm seeing occurs when you overwrite the variable being iterated with the foreach value, in the cases above, $a

[jens1o]

Yes, it has. It really looks like an infinite loop.

I have the same problem, PHP Language Server consume 100% cpu and Load average is +10.
How can I debug was is going on?
The worst is that when I close Atom, PHP Language Server is still running..

[harmboschloo]

I also have a continuous high cpu on windows running with vscode. After vscode closes the process remains with high cpu and I have to kill it manually.

edit: cpu load and memory usage are stable remaining at ~34% and ~115Mb
