Add --purge FILE to remove all caches of FILE. Since the current --remove FILE removes a cache which has same build-id of given FILE. Since the command takes a FILE path, it can confuse user who tries to remove cache about FILE path. ----- # ./perf buildid-cache -v --add ./perf Adding 133b7b5486d987a5ab5c3ebf4ea14941f45d4d4f ./perf: Ok # (update the ./perf binary) # ./perf buildid-cache -v --remove ./perf Removing 305bbd1be68f66eca7e2d78db294653031edfa79 ./perf: FAIL ./perf wasn't in the cache ----- Actually, the --remove's FAIL is not shown, it just silently fails. So, this patch adds --purge FILE action for such usecase. perf buildid-cache --purge FILE removes all caches which has same FILE path. In other words, it removes all caches including old binaries. ----- # ./perf buildid-cache -v --add ./perf Adding 133b7b5486d987a5ab5c3ebf4ea14941f45d4d4f ./perf: Ok # (update the ./perf binary) # ./perf buildid-cache -v --purge ./perf Removing 133b7b5486d987a5ab5c3ebf4ea14941f45d4d4f ./perf: Ok ----- BTW, if you want to purge all the caches, remove ~/.debug/* .
