Delete branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
After merging #248, the Docker container seems to be buffering logs until a sufficient number of lines are present. Then, they're printed all at once. I have no idea what caused this, but this should not be how it is. It should output each log line the moment it receives them.
I'm pretty sure this can be resolved by using
setbuf(stdout, NULL);to disable buffering for stdout (& stderr as well).
