This fix, provided by Paul Kulchenko (@pkulchenko), allows the Lua
scripting engine to evaluate statements with a trailing comment like the
following one:
EVAL "print() --comment" 0
Lua can't parse the above if the string does not end with a newline, so
now a final newline is always added automatically. This does not change
the SHA1 of scripts since the SHA1 is computed on the body we pass to
EVAL, without the other code we add to register the function.
Close#2951.
It's a key invariant that when AOF is enabled, after the cluster
reshards, a crash-recovery event causes all the keys to be still fine
with the expected logical content. Now this is part of unit 04.
The old version was modeled with two failovers, however after the first
it is possible that another slave will migrate to the new master, since
for some time the new master is not backed by any slave. Probably there
should be some pause after a failover, before the migration. Anyway the
test is simpler in this way, and depends less on timing.
HINCRBY* tests later used the value "tmp" that was sometimes generated
by the random key generation function. The result was ovewriting what
Tcl expected to be inside Redis with another value, causing the next
HSTRLEN test to fail.
MOVE was not able to move the TTL: when a key was moved into a different
database number, it became persistent like if PERSIST was used.
In some incredible way (I guess almost nobody uses Redis MOVE) this bug
remained unnoticed inside Redis internals for many years.
Finally Andy Grunwald discovered it and opened an issue.
This commit fixes the bug and adds a regression test.
Close#2765.
This test on Linux was extremely slow, since in Tcl we can't enable
easily tcp-nodelay, so the busy loop used to take *a lot* with bigger
writes. Fixed using pipelining.
People mostly use SORT against lists, but our prior
behavior was pretending lists were an unordered bag
requiring a forced-sort when no sort was requested.
We can just use the native list ordering to ensure
consistency across replicaion and scripting calls.
Closes#2079Closes#545 (again)
start_server now uses return value from Tcl exec to get the server pid,
however this introduces errors that depend from timing: a lot of the
testing code base assumed the server to be actually up and running when
server_start returns.
So the old code that waits to see the pid in the log file was restored.
Basically: test to make sure we can load cmsgpack
and do some sanity checks to make sure pack/unpack works
properly. We also have a bonus test for circular encoding
and decoding because I was curious how it worked.
