Problem: Currently, when performing random distribution verification, we determine the probability of each element occurring in the sum, but the probability is only an estimate, these tests had rare sporadic failures, and we cannot verify what the probability of failure will be. Solution: Using the chi-square distribution instead of the original random distribution validation makes the test more reasonable and easier to find problems.

The cluster bus is established over TLS or non-TLS depending on the configuration tls-cluster. The client ports distributed in the cluster and sent to clients are assumed to be TLS or non-TLS also depending on tls-cluster. The cluster bus is now extended to also contain the non-TLS port of clients in a TLS cluster, when available. The non-TLS port of a cluster node, when available, is sent to clients connected without TLS in responses to CLUSTER SLOTS, CLUSTER NODES, CLUSTER SLAVES and MOVED and ASK redirects, instead of the TLS port. The user was able to override the client port by defining cluster-announce-port. Now cluster-announce-tls-port is added, so the user can define an alternative announce port for both TLS and non-TLS clients. Fixes #8134

In certain scenario start_server may think it failed to start a redis server although it started successfully. in these cases, it'll not terminate it, and it'll remain running when the test is over. In start_server if config doesn't have bind (the minimal.conf in introspection.tcl), it will try to bind ipv4 and ipv6. One may success while other fails. It will output "Could not create server TCP listening socket". wait_server_started uses this message to check whether instance started successfully. So it will consider that it failed even though redis started successfully. Additionally, in some cases it wasn't clear to users why the server exited, since the warning message printed to the log, could in some cases be harmless, and in some cases fatal. This PR adds makes a clear distinction between a warning log message and a fatal one, and changes the test suite to look for the fatal message.

When redis responds with tracking-redir-broken push message (RESP3), it was responding with a broken protocol: an array of 3 elements, but only pushes 2 elements. Some bugs in the test make this pass. Read the push reply will consume an extra reply, because the reply length is 3, but there are only two elements, so the next reply will be treated as third element. So the test is corrected too. Other changes: * checkPrefixCollisionsOrReply success should return 1 instead of -1, this bug didn't have any implications. * improve client tracking tests to validate more of the response it reads.

RAND* commands: fix risk of OOM panic in hash and zset, use fair random in hash, and add tests for even distribution to all (#8429) Changes to HRANDFIELD and ZRANDMEMBER: * Fix risk of OOM panic when client query a very big negative count (avoid allocating huge temporary buffer). * Fix uneven random distribution in HRANDFIELD with negative count (wasn't using dictGetFairRandomKey). * Add tests to check an even random distribution (HRANDFIELD, SRANDMEMBER, ZRANDMEMBER).

* The corrupt dump fuzzer found a division by zero. * in some cases the random fields from the HRANDFIELD tests produced fields with newlines and other special chars (due to \ char), this caused the TCL tests to see a bulk response that has a newline in it and add {} around it, later it can think this is a nested list. in fact the `alpha` random string generator isn't using spaces and newlines, so it should not use `\` either.

New commands: `HRANDFIELD [<count> [WITHVALUES]]` `ZRANDMEMBER [<count> [WITHSCORES]]` Algorithms are similar to the one in SRANDMEMBER. Both return a simple bulk response when no arguments are given, and an array otherwise. In case values/scores are requested, RESP2 returns a long array, and RESP3 a nested array. note: in all 3 commands, the only option that also provides random order is the one with negative count. Changes to SRANDMEMBER * Optimization when count is 1, we can use the more efficient algorithm of non-unique random * optimization: work with sds strings rather than robj Other changes: * zzlGetScore: when zset needs to convert string to double, we use safer memcpy (in case the buffer is too small) * Solve a "bug" in SRANDMEMBER test: it intended to test a positive count (case 3 or case 4) and by accident used a negative count Co-authored-by:

It was confusing as to why these don't return a map type. the reason is that order matters, so we need to make sure the client library knows to respect it. Added comments in the implementation and tests to cover it.

This adds basic coverage to IO threads by running the cluster and few selected Redis test suite tests with the IO threads enabled. Also provides some necessary additional improvements to the test suite: * Add --config to sentinel/cluster tests for arbitrary configuration. * Fix --tags whitelisting which was broken. * Add a `network` tag to some tests that are more network intensive. This is work in progress and more tests should be properly tagged in the future.

Add INFO field, rdb_active_cow_size, to report COW of a live fork child while it's active. - once in 1024 keys check the time, and if there's more than one second since the last report send a report to the parent via the pipe. - refactor the child_info_data struct, it's an implementation detail that shouldn't be in the server struct, and not used to communicate data between caller and callee - remove the magic value from that struct (not sure what it was good for), and instead add handling of short reads. - add another value to the structure, cow_type, to indicate if the report is for the new rdb_active_cow_size field, or it's the last report of a successful operation - add new Module API to report the active COW - add more asserts variants to test.tcl

When a Lua script returns a map to redis (a feature which was added in redis 6 together with RESP3), it would have returned the value first and the key second. If the client was using RESP2, it was getting them out of order, and if the client was in RESP3, it was getting a map of value => key. This was happening regardless of the Lua script using redis.setresp(3) or not. This also affects a case where the script was returning a map which it got from from redis by doing something like: redis.setresp(3); return redis.call() This fix is a breaking change for redis 6.0 users who happened to rely on the wrong order (either ones that used redis.setresp(3), or ones that returned a map explicitly). This commit also includes other two changes in the tests: 1. The test suite now handles RESP3 maps as dicts rather than nested lists 2. Remove some redundant (duplicate) tests from tracking.tcl

This Commit pushes forward the observability on overall error statistics and command statistics within redis-server: It extends INFO COMMANDSTATS to have - failed_calls in - so we can keep track of errors that happen from the command itself, broken by command. - rejected_calls - so we can keep track of errors that were triggered outside the commmand processing per se Adds a new section to INFO, named ERRORSTATS that enables keeping track of the different errors that occur within redis ( within processCommand and call ) based on the reply Error Prefix ( The first word after the "-", up to the first space ). This commit also fixes RM_ReplyWithError so that it can be correctly identified as an error reply.

Apparently the "leaks" took reports a different error string about process that's not found in each version of MacOS. This cause the test suite to fail on some OS versions, since some tests terminate the process before looking for leaks. Instead of looking at the error string, we now look at the (documented) exit code.

Add a new set of defrag functions that take a defrag context and allow defragmenting memory blocks and RedisModuleStrings. Modules can register a defrag callback which will be invoked when the defrag process handles globals. Modules with custom data types can also register a datatype-specific defrag callback which is invoked for keys that require defragmentation. The callback and associated functions support both one-step and multi-step options, depending on the complexity of the key as exposed by the free_effort callback.

This adds a new `tls-client-cert-file` and `tls-client-key-file` configuration directives which make it possible to use different certificates for the TLS-server and TLS-client functions of Redis. This is an optional directive. If it is not specified the `tls-cert-file` and `tls-key-file` directives are used for TLS client functions as well. Also, `utils/gen-test-certs.sh` now creates additional server-only and client-only certs and will skip intensive operations if target files already exist.

when using --baseport to run two tests suite in parallel (different folders), we need to also make sure the port used by the testsuite to communicate with it's workers is unique. otherwise the attept to find a free port connects to the other test suite and messes it. maybe one day we need to attempt to bind, instead of connect when tring to find a free port.

The test creates keys with various encodings, DUMP them, corrupt the payload and RESTORES it. It utilizes the recently added use-exit-on-panic config to distinguish between asserts and segfaults. If the restore succeeds, it runs random commands on the key to attempt to trigger a crash. It runs in two modes, one with deep sanitation enabled and one without. In the first one we don't expect any assertions or segfaults, in the second one we expect assertions, but no segfaults. We also check for leaks and invalid reads using valgrind, and if we find them we print the commands that lead to that issue. Changes in the code (other than the test): - Replace a few NPD (null pointer deference) flows and division by zero with an assertion, so that it doesn't fail the test. (since we set the server to use `exit` rather than `abort` on assertion). - Fix quite a lot of flows in rdb.c that could have lead to memory leaks in RESTORE command (since it now responds with an error rather than panic) - Add a DEBUG flag for SET-SKIP-CHECKSUM-VALIDATION so that the test don't need to bother with faking a valid checksum - Remove a pile of code in serverLogObjectDebugInfo which is actually unsafe to run in the crash report (see comments in the code) - fix a missing boundary check in lzf_decompress test suite infra improvements: - be able to run valgrind checks before the process terminates - rotate log files when restarting servers

When loading an encoded payload we will at least do a shallow validation to check that the size that's encoded in the payload matches the size of the allocation. This let's us later use this encoded size to make sure the various offsets inside encoded payload don't reach outside the allocation, if they do, we'll assert/panic, but at least we won't segfault or smear memory. We can also do 'deep' validation which runs on all the records of the encoded payload and validates that they don't contain invalid offsets. This lets us detect corruptions early and reject a RESTORE command rather than accepting it and asserting (crashing) later when accessing that payload via some command. configuration: - adding ACL flag skip-sanitize-payload - adding config sanitize-dump-payload [yes/no/clients] For now, we don't have a good way to ensure MIGRATE in cluster resharding isn't being slowed down by these sanitation, so i'm setting the default value to `no`, but later on it should be set to `clients` by default. changes: - changing rdbReportError not to `exit` in RESTORE command - adding a new stat to be able to later check if cluster MIGRATE isn't being slowed down by sanitation.

Test support for the new map, null and push message types. Map objects are parsed as a list of lists of key value pairs. for instance: user => john password => 123 will be parsed to the following TCL list: {{user john} {password 123}} Also added the following tests: Redirection still works with RESP3 Able to use a RESP3 client as a redirection client No duplicate invalidation messages when turning BCAST mode on after normal tracking Server is able to evacuate enough keys when num of keys surpasses limit by more than defined initial effort Different clients using different protocols can track the same key OPTOUT tests OPTIN tests Clients can redirect to the same connection tracking-redir-broken test HELLO 3 checks Invalidation messages still work when using RESP3, with and without redirection Switching to RESP3 doesn't disturb previous tracked keys Tracking info is correct Flushall and flushdb produce invalidation messages These tests achieve 100% line coverage for tracking.c using lcov.

The tests sometimes fail to find a log message. Recently i added a print that shows the log files that are searched and it shows that the message was in deed there. The only reason i can't think of for this seach to fail, is we we happened to read an incomplete line, which didn't match our pattern and then on the next iteration we would continue reading from the line after it. The fix is to always re-evaluation the previous line.

if there are nested tests and nested servers, we need to restore the previous value of cur_test when a test exist. example: ``` test{test 1} { start_server { test{test 1.1 - master only} { } start_server { test{test 1.2 - with replication} { } } } } ``` when `test 1.1 - master only exists`, we're still inside `test 1` -

There is an inherent race condition in port allocation for spawned servers. If a server fails to start because a port is taken, a new port is allocated. This fixes a problem where the logs are not truncated and as a result a large number of unmonitored servers are started.

Starting redis 6.0 and the changes we made to the diskless master to be suitable for TLS, I made the master avoid reaping (wait3) the pid of the child until we know all replicas are done reading their rdb. I did that in order to avoid a state where the rdb_child_pid is -1 but we don't yet want to start another fork (still busy serving that data to replicas). It turns out that the solution used so far was problematic in case the fork child was being killed (e.g. by the kernel OOM killer), in that case there's a chance that we currently disabled the read event on the rdb pipe, since we're waiting for a replica to become writable again. and in that scenario the master would have never realized the child exited, and the replica will remain hung too. Note that there's no mechanism to detect a hung replica while it's in rdb transfer state. The solution here is to add another pipe which is used by the parent to tell the child it is safe to exit. this mean that when the child exits, for whatever reason, it is safe to reap it. Besides that, i'm re-introducing an adjustment to REPLCONF ACK which was part of #6271 (Accelerate diskless master connections) but was dropped when that PR was rebased after the TLS fork/pipe changes (5a477946). Now that RdbPipeCleanup no longer calls checkChildrenDone, and the ACK has chance to detect that the child exited, it should be the one to call it so that we don't have to wait for cron (server.hz) to do that.

- 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.
