Struct ObjFileCache

internal/server/obj-cache.go:18–24

ObjFileCache is a /tmp/nocc/obj/obj-cache directory, where the resulting .o files are saved. Its purpose is to reuse a ready .o file if the same .cpp is requested to be compiled again. This is especially useful to share .o files across build agents: if one build agent compiles the master branch, oth

// The hardest problem is how to detect that "this .cpp was already compiled, we can use .o".
// See ObjFileCache.MakeObjCacheKey.
type ObjFileCache struct {
	*FileCache

	// next to obj-cache, there is a /tmp/nocc/obj/cxx-out directory (session.objOutFile point here)
	// after being compiled, files from here are hard linked to obj-cache
	objTmpDir string
}
