1) cur_test: when restart_server, "no such variable" error occurs
./runtest --single integration/rdb
test {client freed during loading}
SET ::cur_test
restart_server
kill_server
test "Check for memory leaks (pid $pid)"
SET ::cur_test
UNSET ::cur_test
UNSET ::cur_test // This global variable has been unset.
2) `ps --ppid` not available on macOS platform, can be replaced with
`pgrep -P pid`.
(cherry picked from commit e90385e2232d41fd7c40dc239279f9837e7bdf57)
- redirect valgrind reports to a dedicated file rather than console
- try to avoid killing instances with SIGKILL so that we get the memory
leak report (killing with SIGTERM before resorting to SIGKILL)
- search for valgrind reports when done, print them and fail the tests
- add --dont-clean option to keep the logs on exit
- fix exit error code when crash is found (would have exited with 0)
changes that affect the normal redis test suite:
- refactor check_valgrind_errors into two functions one to search and
one to report
- move the search half into util.tcl to serve the cluster tests too
- ignore "address range perms" valgrind warnings which seem non relevant.
(cherry picked from commit da723a917dec7f2514d821a615668e158bb4f60c)
reduce code duplication in aof.tcl.
move creation of clients into the test so that it can be skipped
(cherry picked from commit cc455a710cc68d0fd8243cd1f04c5ee7332e4fdb)
- the test now waits for specific set of log messages rather than wait for
timeout looking for just one message.
- we don't wanna sample the current length of the log after an action, due
to a race, we need to start the search from the line number of the last
message we where waiting for.
- when attempting to trigger a full sync, use multi-exec to avoid a race
where the replica manages to re-connect before we completed the set of
actions that should force a full sync.
- fix verify_log_message which was broken and unused
(cherry picked from commit 06aaeabaea9d9b248e8a790dde352cd14d66628a)
tests were sensitive to additional log lines appearing in the log
causing the search to come empty handed.
instead of just looking for the n last log lines, capture the log lines
before performing the action, and then search from that offset.
(cherry picked from commit efc4189b6227a17f26ed9bd6bbac62bf4bf7ab66)
i.e. don't start the search from scratch hitting the used ones again.
this will also reduce the likelihood of collisions (if there are any
left) by increasing the time until we re-use a port we did use in the
past.
apparently when running tests in parallel (the default of --clients 16),
there's a chance for two tests to use the same port.
specifically, one test might shutdown a master and still have the
replica up, and then another test will re-use the port number of master
for another master, and then that replica will connect to the master of
the other test.
this can cause a master to count too many full syncs and fail a test if
we run the tests with --single integration/psync2 --loop --stop

* Introduce a connection abstraction layer for all socket operations and
integrate it across the code base.
* Provide an optional TLS connections implementation based on OpenSSL.
* Pull a newer version of hiredis with TLS support.
* Tests, redis-cli updates for TLS support.
now that replica can read rdb directly from the socket, it should avoid exiting
on short read and instead try to re-sync.
this commit tries to have minimal effects on non-diskless rdb reading.
and includes a test that tries to trigger this scenario on various read cases.
The implementation of the diskless replication was currently diskless only on the master side.
The slave side was still storing the received rdb file to the disk before loading it back in and parsing it.
This commit adds two modes to load rdb directly from socket:
1) when-empty
2) using "swapdb"
the third mode of using diskless slave by flushdb is risky and currently not included.
other changes:
--------------
distinguish between aof configuration and state so that we can re-enable aof only when sync eventually
succeeds (and not when exiting from readSyncBulkPayload after a failed attempt)
also a CONFIG GET and INFO during rdb loading would have lied
When loading rdb from the network, don't kill the server on short read (that can be a network error)
Fix rdb check when performed on preamble AOF
tests:
run replication tests for diskless slave too
make replication test a bit more aggressive
Add test for diskless load swapdb
Some inline test moved into server_is_up procedure.
Also find_available_port was moved into util since it is going
to be used for the Sentinel test as well.
A new stress test was added to stress test the code converting a ziplist
into an hash table.
In this commit also randomValue helper function was modified to also
return negative values.
wait_for_condition is now used instead of the usual "after 1000" (that
is the way to sleep in Tcl). This should avoid to find the replica in
a state where it is loading the RDB in memory, returning -LOADING error.
This test used to fail when running the test over valgrind, due to the
added latencies.
Commit 2f22d57a5219aaabe088cc4e64624d3d3fccf760 modified the name of a
few INFO fields. This commit changes the Redis test to account for this
changes.
Due to a change in the format of the bug report in case of crash of
failed assertion the test suite was no longer able to properly log it.
Instead just a protocol error was logged by the Redis TCL client that
provided no clue about the actual problem.
This commit resolves the issue by logging everything from the first line
of the log including the string REDIS BUG REPORT, till the end of the
file.
