Redis [BUG] "make test" fails with [exception]: Executing test client: tail: + 28: No such file or directory.

VERSION: 6.0.6 DESCRIPTION: Post-build automated testing fails with error. REPRODUCTION: run make test EXPECTATION: Success.

This is in reference to the now-closed #7605 issue.

My version of macOS comes with tclsh 8.5.9 I used MacPorts to install 8.6.10 then re-ran make test I now have some fresh errors:

. . .
[ok]: Detect write load to master
[ok]: Test replication partial resync: no backlog (diskless: yes, disabled, reconnect: 1)
[ok]: Check for memory leaks (pid 43538)
[ok]: Check for memory leaks (pid 43520)
[ok]: Master stream is correctly processed while the replica has a script in -BUSY state
[ok]: Check for memory leaks (pid 43128)
[ok]: Check for memory leaks (pid 43118)
[ok]: Slave should be able to synchronize with the master
[ok]: Detect write load to master
[ok]: slave fails full sync and diskless load swapdb recovers it

[ok]: Master stream is correctly processed while the replica has a script in -BUSY state [ok]: Test replication partial resync: ok psync (diskless: yes, swapdb, reconnect: 1) [ok]: slave fails full sync and diskless load swapdb recovers it [ok]: Slave should be able to synchronize with the master [ok]: Detect write load to master
