In the distant history there was only the read flag for commands, and whatever command that didn't have the read flag was a write one. Then we added the write flag, but some portions of the code still used !read Also some commands that don't work on the keyspace at all, still have the read flag. Changes in this commit: 1. remove the read-only flag from TIME, ECHO, ROLE and LASTSAVE 2. EXEC command used to decides if it should propagate a MULTI by looking at the command flags (!read & !admin). When i was about to change it to look at the write flag instead, i realized that this would cause it not to propagate a MULTI for PUBLISH, EVAL, and SCRIPT, all 3 are not marked as either a read command or a write one (as they should), but all 3 are calling forceCommandPropagation. So instead of introducing a new flag to denote a command that "writes" but not into the keyspace, and still needs propagation, i decided to rely on the forceCommandPropagation, and just fix the code to propagate MULTI when needed rather than depending on the command flags at all. The implication of my change then is that now it won't decide to propagate MULTI when it sees one of these: SELECT, PING, INFO, COMMAND, TIME and other commands which are neither read nor write. 3. Changing getNodeByQuery and clusterRedirectBlockedClientIfNeeded in cluster.c to look at !write rather than read flag. This should have no implications, since these code paths are only reachable for commands which access keys, and these are always marked as either read or write. This commit improve MULTI propagation tests, for modules and a bunch of other special cases, all of which used to pass already before that commit. the only one that test change that uncovered a change of behavior is the one that DELs a non-existing key, it used to propagate an empty multi-exec block, and no longer does. |
