Cache wasn't restored successfully

[kenorb]

I don't think caching works properly.

First run worked fine:

Run johelegp/gcc-snapshot@v1
/usr/bin/tar --posix --use-compress-program zstd -T0 -cf cache.tzst -P -C /home/runner/work/Foo/Bar --files-from manifest.txt
Cache Size: ~0 MB (22 B)
Cache saved successfully
...
Run g++ --version
g++ (GCC) 13.0.0 20220911 (experimental)

Second run, restored cache, but g++ is the same as it was before:

Run johelegp/gcc-snapshot@v1
Received 22 of 22 (100.0%), 0.0 MBs/sec
Cache Size: ~0 MB (22 B)
/usr/bin/tar --use-compress-program zstd -d -xf /home/runner/work/_temp/eb5035af-977b-.../cache.tzst -P -C /home/runner/work/Foo/Bar
Cache restored successfully
...
Run g++ --version
g++ (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0

Thank you for reporting this.

It seems that caching always succeeds with 22 bytes. Perhaps something changed with the condition of restorage, since this used to work.

gcc-snapshot/index.js

Line 16 in c7b5c01

return [ (await cache.restoreCache(paths, key, Array()) !== undefined), key ];

gcc-snapshot/index.js

Lines 41 to 42 in c7b5c01

	const [ restored, key ] = await restoreCache();
	if (!restored)

I actually wanted this to be a composite action rather than a JavaScript action. Now that the limitations of composite actions have been lifted, perhaps I can restore the original composite action.
