Downloaded components posing as not downloaded

[jrichter1]

Some components never seem to act like they have been downloaded. The file sizes might be wrong.

[jrichter1]

The sizes don't match, I'm going to keep this open as a reminder for when we update to the release candidates.

[jrichter1]

And strangely enough, it looks like some files actually return different sizes on different systems.

[mohitsuman]

@jrichter1 Which components are these, I will check them individually for the file size.

[jrichter1]

@mohitsuman from what I've experienced, it was: devstudio, CDK (mac only), kompose and fuse platform (EAP one)
The really weird thing though, fs.stat returns different size for devstudio for each OS I've tried, even though it is the same file

[dgolovin]

could that be related to node.js version we use to build in Central CI?
@jrichter1 @mohitsuman I installed version 8 on my mac mini and it works as expected.

[jrichter1]

@dgolovin all fs.stat does is call the appropriate stat function from the terminal and put the results into an object
And from what I have seen, different OSes (or indeed different file systems) just return slightly different values.

For example, what stat returns for devstudio:

• mac 11.15.4: 677694419
• win10: 677689480

Problem is mkdirp.sync(this.downloadFolder); call inside InstallableItem constructor. It has different behavior between mac and windows. On windows if targeted folder exists execution continues, on mac it throws exception. It means everything is fine for first execution when no cache folder and it starts to behave wrong for all consecutive times.

Fuse on EAP still has a different size to what is in requirements.json for me. Anyone care to verify?

[dgolovin]

I'll check it, it is probably related to fact that Fuse on EAP is downloading two files under the hood, not one.

[mohitsuman]

On macOS, these are the 2 files which are getting downloaded & installed.
_fuse-eap-installer-6.3.0.redhat-187.jar : 234.9 MB
jboss-eap-6.4.0.GA-installer.jar : 201.3 MB

On the UI selection page, it shows 217.49 MB.

@mohitsuman Problem is even it is downloaded it is still marked as Selected for download, could you confirm that?

[mohitsuman]

@dgolovin Yeah it is marked as Selected for download.

I've opened issue specific to components that require more than one resource to download #995
