log file is written on each poll

I get the following logs in the eclipse console on each wwd-poll and it writes a log file for each poll in the eclipse/.metadata-folder. I did not configure anything with wwd. I only installed it and it makes such a noise by making polls and repeated logs:

[Info]	Using @angular/language-service v9.0.0-next.8 from /Applications/Eclipse.app/Contents/Eclipse/plugins/org.eclipse.wildwebdeveloper_0.5.3.201912031954/language-servers/node_modules/@angular/language-service

On each poll, this log is shown and a log file is written in /Users/workspace/ide/.metadata/. I have found out that wwd writes over 3000 log files - so much garbage with same messages which can be avoided by default. Why does wwd makes so much logs and why does wwd-log says:

Using less efficient polling watcher. Set TSC_NONPOLLING_WATCHER to true.

Why does wwd not use the more efficient polling watcher by default when it already knows that it uses a less efficient polling watcher?

Disabling language service for /Users/workspace/ide/test/src/main/webapp/WEB-INF/tsconfig.json because it is not an Angular project.

Why does wwd annoy me with such messages when wwd already knows that this is not an angular project?

Hello @nimo23

I just started to investigate your problem. I will try to summarize all problems and solutions.

• There is multiple log files under /Users/workspace/ide/.metadata/ folder
  • Problem comes from the launch of angular language server: see https://github.com/eclipse/wildwebdeveloper/blob/8fb84afcc8a3e9d34db601ab8af5470b912cd3ac/org.eclipse.wildwebdeveloper/src/org/eclipse/wildwebdeveloper/angular/AngularLanguageServer.java#L40-L41
  • I think we should not use a timestamp in the log file name.
  • We should verify preferences about logging angular language server. If I understand correctly the documentation of Angular Language Service, logging is disabled if there is no log file.
• Angular Language Server is launch in debug mode
  • Obviously this line is the one to modify. https://github.com/eclipse/wildwebdeveloper/blob/8fb84afcc8a3e9d34db601ab8af5470b912cd3ac/org.eclipse.wildwebdeveloper/src/org/eclipse/wildwebdeveloper/angular/AngularLanguageServer.java#L53
• Angular language server use less efficient polling watcher
  • Accordingly to the implementation of the log, we should add an environment variable named TSC_NONPOLLING_WATCHER with value to true. See https://github.com/angular/vscode-ng-language-service/blob/master/server/src/server.ts#L50-L52
  • I don’t know what is the impact of doing this modification. I will not modify this for the moment.
• Angular language server should not be launch when the project is not an angular project
  • I think we should create another issue for this point
• There are multiple folders with log files under eclipse.app->Contents/MacOs
  • I can’t reproduce because I haven’t an Apple laptop. I hope my following patch will help.

Now I will work on the codebase in order to provide a patch about log files.

We can release Wild Web Developer any time. Last release was last week. Is there any change you think is worth releasing soon?
