Simplify removeUnusedExtensions about commerce-gradle-plugin HOT 10 CLOSED

Unpacking platform in sparse mode
Loaded extensions information from project custom folder in 39 ms
Loaded extensions information from hybrisPlatform dependencies in 2628 ms
Loaded all needed extensions from localextensions.xml in 1 ms
Loaded existing extensions information from project folder in 655 ms
No missing SAP Commerce extensions, nothing to unpack

This is from 2211.2 with intextpack 2211.3, on an M1 Max. With these numbers in mind, I do not believe we need any caching of extension info. I would make the PR as is and we can add caching if needed.

This is the run on a Windows machine:

Unpacking platform in sparse mode
Loaded extensions information from project custom folder in 160 ms
Loaded extensions information from hybrisPlatform dependencies in 10539 ms
Loaded all needed extensions from localextensions.xml in 2 ms
Loaded existing extensions information from project folder in 107 ms
Some needed SAP Commerce Suite extensions are missing, copying them

It is slower, but still good enough to not require any extra optimization/caching.

Thanks for reporting the issue!

I'm using Gradle / Java to delete the files/folders to be OS-agnostic, but you are definitely right about the performance.
Because now that you mention it, I had the same issues when implementing cleanPlatform

Long story short: project.delete is not fast enough, need to either use native Java or OS calls like you mentioned :)

How about, instead of cleaning up the unused extensions, we extract from the platform zip only the ones needed by local extensions.xml (and dependencies)? If we could improve the extractions of the platform in that direction, I can help with the implementation.

Thats sounds imteresting!

I guess you would:
build the complete dependency tree by parsing all extensioninfo.xml files across all zips (dependency configuration hybrisPlatform), resolve it against localextensions.xml and based on the pruned tree, unpakck only what's necessary.

from commerce-gradle-plugin.

Something along the line:

• phase 1: gather information about all extensions and their direct dependencies
  • gather information about all extensions in the custom folder by parsing the extensioninfo.xml files in there and building a list of objects describing each extension and its direct declared dependencies (e.g. ExtensionInformation)
  • gather information about all extensions in the commerce suite zip (obtained from project dependency configuration hybrisPlatform) by parsing the extensioninfo.xml files in the zip and build also for them a lost of extension objects
  • repeat the above step also for the optional integration extension pack (if it is declared)
  • add the platform dependency as a must (a single extension for the entire platform should be enough, not each individual extension in platform/ext, as the platform entirely should be always present
    -phase 2: build the list of needed hybris dependencies to be present
  • add the platform extension
  • for each extension declared in localextensions.xml, add it in the needed list, then add its dependencies, recursively
• phase 3: build the list of extensions already present in the hybris bin dir (not in the zip, but the project folder)
• phase 4: find the missing extensions, by removing from the needed list the present ones
• phase 5: extract from the zips (hybris commerce suite and integration pack) the missing extensions

Since the entire parsing of all the extensioninfo.xml files in the commerce suite zip and intpack zip can take some time, to make the next builds faster, we can save the resulting list of extension information objects in a file in the project cache directory and use that file as long as we do not need a different version of the commerce suite or intpack.

As soon as the version of the commerce suite dependency or of the intpack dependency changes from what we saved in the project cache, we proceed to delete the entire hybris bin/modules and bin/platform folders and start over with the steps above.

Another nice bonus we can have is to unzip some "always needed" extensions (e.g. yempty, yocc, ybackoffice), that are handy to have for ant extgen but we do not want them declared in the localextensions.xml of any project. We can configure these as a list property of our plugin.

What do you think?

from commerce-gradle-plugin.

I like both, the idea and the proposal. Do we have some dry runs to determine what the actual effect on the build time really is? (Just interested in it)

Besides the decrease of build times it will also safe disk space, which i also like.

You got my vote up 👍

from commerce-gradle-plugin.

I also like both the idea and the proposal, feel free to go ahead and submit a PR!

A few additional remarks:

• the new behavior should be opt-in
• this idea deserves its own section in the plugin config
• tests!!

hybris {
    sparseBootstrap {
        enabled.set(true)
        alwaysIncluded.set(listOf("yempty", ...))
    }
}

(Disclaimer: I just quickly typed this up. Suggestions for better names, different structure, ... are always welcome)

Good, then I will implement this in between next week and we will see how it goes.
