I can confirm that unsetting HASH_DIRS makes HASH_CMDS behave as I
expect. That is, after a successful invocation of rsync,
rsync=/usr/bin/rsync gets hashed.
This implies that invoking any non-existing command with HASH_DIRS set
effectively disables HASH_CMDS. The following test confirms it:
% sudo docker run -e TERM -it --rm zshusers/zsh:5.8
# does-not-exist
zsh: command not found: does-not-exist
# apt-get update && apt-get install -y rsync
# rsync
rsync version 3.1.2 protocol version 31
# print $+commands[rsync]
0
Do I understand it correctly that this is working as intended? It
appears to contradict the documentation for HASH_CMDS, which states
that commands are hashed when they are invoked for the first time.
Roman.
