Gitian includes two caches where build-assets may be saved for use with
|
|
subsequent builds.
|
|
|
|
Common cache:
|
|
All descriptors share this cache. It can be useful for storing fetched sources,
|
|
sharing build assets between descriptors, etc.
|
|
To add or update files, copy them to ~/cache/common from the build script.
|
|
|
|
Per-descriptor cache
|
|
Files installed to this cache can only be seen by this descriptor. Use this to
|
|
store assets created as part of the build process, to avoid having to rebuild
|
|
them in future builds.
|
|
To add or update files, copy them to ~/cache/$NAME from the build script, where
|
|
$NAME is the value of the descriptor's "name" key.
|
|
|
|
Before each build, all files and folders in the cache directories will be
|
|
transferred to the VM. After each successful build, the caches will be
|
|
transferred back to the builder (overwriting existing files as necessary).
|
|
|
|
It is entirely up to the user and the descriptors to verify that cached files
|
|
are actually suitable for re-use. Overwriting existing cached files is _highly_
|
|
discouraged, as that would likely lead to non-deterministic results. Unique
|
|
filenames should always be used.
