When using the MIGRATE, with a destination Redis that has the user name or password set to the string "keys", Redis would have determine the wrong set of key names the command is gonna access. This lead to ACL returning wrong authentication result. Destination instance: ``` 127.0.0.1:6380> acl setuser default >keys OK 127.0.0.1:6380> acl setuser keys on nopass ~* &* +@all OK ``` Source instance: ``` 127.0.0.1:6379> set a 123 OK 127.0.0.1:6379> acl setuser cc on nopass ~a* +@all OK 127.0.0.1:6379> auth cc 1 OK 127.0.0.1:6379> migrate 127.0.0.1 6380 "" 0 1000 auth keys keys a (error) NOPERM this user has no permissions to access one of the keys used as arguments 127.0.0.1:6379> migrate 127.0.0.1 6380 "" 0 1000 auth2 keys pswd keys a (error) NOPERM this user has no permissions to access one of the keys used as arguments ``` Using `acl dryrun` we know that the parameters of `auth` and `auth2` are mistaken for the `keys` option. ``` 127.0.0.1:6379> acl dryrun cc migrate whatever whatever "" 0 1000 auth keys keys a "This user has no permissions to access the 'keys' key" 127.0.0.1:6379> acl dryrun cc migrate whatever whatever "" 0 1000 auth2 keys pswd keys a "This user has no permissions to access the 'pswd' key" ``` Fix the bug by editing db.c/migrateGetKeys function, which finds the `keys` option and all the keys following.
Redis Test Suite
The normal execution mode of the test suite involves starting and manipulating
local redis-server instances, inspecting process state, log files, etc.
The test suite also supports execution against an external server, which is
enabled using the --host and --port parameters. When executing against an
external server, tests tagged external:skip are skipped.
There are additional runtime options that can further adjust the test suite to match different external server configurations:
| Option | Impact |
|---|---|
--singledb |
Only use database 0, don't assume others are supported. |
--ignore-encoding |
Skip all checks for specific encoding. |
--ignore-digest |
Skip key value digest validations. |
--cluster-mode |
Run in strict Redis Cluster compatibility mode. |
--large-memory |
Enables tests that consume more than 100mb |
Tags
Tags are applied to tests to classify them according to the subsystem they test, but also to indicate compatibility with different run modes and required capabilities.
Tags can be applied in different context levels:
start_servercontexttagscontext that bundles several tests together- A single test context.
The following compatibility and capability tags are currently used:
| Tag | Indicates |
|---|---|
external:skip |
Not compatible with external servers. |
cluster:skip |
Not compatible with --cluster-mode. |
large-memory |
Test that requires more than 100mb |
tls:skip |
Not compatible with --tls. |
needs:repl |
Uses replication and needs to be able to SYNC from server. |
needs:debug |
Uses the DEBUG command or other debugging focused commands (like OBJECT). |
needs:pfdebug |
Uses the PFDEBUG command. |
needs:config-maxmemory |
Uses CONFIG SET to manipulate memory limit, eviction policies, etc. |
needs:config-resetstat |
Uses CONFIG RESETSTAT to reset statistics. |
needs:reset |
Uses RESET to reset client connections. |
needs:save |
Uses SAVE to create an RDB file. |
When using an external server (--host and --port), filtering using the
external:skip tags is done automatically.
When using --cluster-mode, filtering using the cluster:skip tag is done
automatically.
When not using --large-memory, filtering using the largemem:skip tag is done
automatically.
In addition, it is possible to specify additional configuration. For example, to
run tests on a server that does not permit SYNC use:
./runtest --host <host> --port <port> --tags -needs:repl
