Background

• Fetching icon set repository with git submodules
• Clone was taking a very long time. (20 minutes or more depending on the environment)
• It took a lot of disk space.
• Editors such as VS Codes have poor performance in repositories with many submodules

Changes

• Introduced fetcher instead of git submodules. This is a git wrapper script.
• Get the files by running git clone --filter=tree:0 --no-checkout **** **** git sparse-checkout set --cone ****. It contains only the files required by the project.
• Significantly reduced network transfer and disk consumption.
• Also, execute this up to 10 processes in parallel.

Speed up CI

CI execution time has been cut in half.

• Before improvement: 11~14 minutes
• After improvement: 6~7 minutes

Icon fetch speeds up to x12!

• Before: 4m 6s
• After improvement: 0m 20s

Since CI used --depth=1 before the improvement, the improvement in the local environment that does not use this option is even greater.
