      Add DEBUG_ASSERTIONS option to custom assert (#12667) · 88e83e51
      Roshan Khatri authored
      This PR introduces a new macro, serverAssertWithInfoDebug, to do complex assertions only for debugging. The main intention is to allow running complex operations during tests without impacting runtime performance. This assertion is enabled when setting DEBUG_ASSERTIONS.
      
      The DEBUG_ASSERTIONS flag is set for the daily and CI variants of `test-sanitizer-address`.

      Use cross-platform-actions for FreeBSD support. (#12732) · 6223355c
      Yossi Gottlieb authored
      This change overcomes many stability issues experienced with the
      vmactions action.
      
      We need to limit VMs to 8GB for better stability, as the 13GB default
      seems to hang them occasionally.
      
      Shell code has been simplified since this action seem to use `bash -e`
      which will abort on non-zero exit codes anyway.

      Fix some compile warnings and errors when building with gcc-12 or clang (#12035) · 42c8c618
      sundb authored
      This PR is to fix the compilation warnings and errors generated by the latest
      complier toolchain, and to add a new runner of the latest toolchain for daily CI.
      
      ## Fix various compilation warnings and errors
      
      1) jemalloc.c
      
      COMPILER: clang-14 with FORTIFY_SOURCE
      
      WARNING:
      ```

                      ^
      ```
      
      REASON:  the compiler to alert developers to potential issues with string concatenation
      that may miss a comma,
      just like #9534 which misses a comma.
      
      SOLUTION: use `()` to tell the compiler that these two line strings are continuous.
      
      2) config.h
      
      COMPILER: clang-14 with FORTIFY_SOURCE
      
      WARNING:

      ```
      
      REASON: Enabling _FORTIFY_SOURCE will cause the compiler to use `strcpy()` with check,
      it results in a deprecated attribute declaration after including <features.h>.
      
      SOLUTION: move the deprecated attribute declaration from config.h to fmacro.h before "#include <features.h>".
      
      3) networking.c
      
      COMPILER: GCC-12

      REASON: GCC-12 predicts that digits10() may return 9 or 10 through `return 9 + (v >= 1000000000UL)`.
      
      SOLUTION: add an assert to let the compiler know the possible length;

      ```
      
      REASON: when _FORTIFY_SOURCE is enabled, the compiler will use the print() with
      check, which is a macro. this may result in the use of directives within the macro, which
      is undefined behavior.
      
      SOLUTION: move the directives-related code out of `print()`.

      ```
      
      REASON: The compiler thinks that the `argc` returned by `sdssplitlen()` could be 0,
      resulting in an empty array of size 0 being passed to lookupCommandLogic.
      this should be a false positive, `argc` can't be 0 when strings are not NULL.
      
      SOLUTION: add an assert to let the compiler know that `argc` is positive.

      ```
      
      REASON: due to the bug[https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80922], when
      enable LTO, gcc-12 will not see `diagnostic ignored "-Wstringop-overread"`, resulting in a warning.
      
      SOLUTION: temporarily set SHA1Update to noinline to avoid compiler warnings due
      to LTO being enabled until the above gcc bug is fixed.
      
      7) zmalloc.h

         59 |   return __builtin___memset_chk (__dest, __ch, __len,
      ```
      
      REASON: due to the GCC-12 bug [https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96503],
      GCC-12 cannot see alloc_size, which causes GCC to think that the actual size of memory
      is 0 when checking with __glibc_objsize0().
      
      SOLUTION: temporarily set malloc-related interfaces to `noinline` to avoid compiler warnings
      due to LTO being enabled until the above gcc bug is fixed.
      
      ## Other changes
      1) Fixed `ps -p [pid]`  doesn't output `<defunct>` when using procps 4.x causing `replication
        child dies when parent is killed - diskless` test to fail.
      2) Add a new fortify CI with GCC-13 and ubuntu-lunar docker image.

      Attempt to solve MacOS CI issues in GH Actions (#12013) · 997fa41e
      Oran Agra authored
      The MacOS CI in github actions often hangs without any logs. GH argues that
      it's due to resource utilization, either running out of disk space, memory, or CPU
      starvation, and thus the runner is terminated.
      
      This PR contains multiple attempts to resolve this:
      1. introducing pause_process instead of SIGSTOP, which waits for the process
        to stop before resuming the test, possibly resolving race conditions in some tests,
        this was a suspect since there was one test that could result in an infinite loop in that
       case, in practice this didn't help, but still a good idea to keep.
      2. disable the `save` config in many tests that don't need it, specifically ones that use
        heavy writes and could create large files.
      3. change the `populate` proc to use short pipeline rather than an infinite one.
      4. use `--clients 1` in the macos CI so that we don't risk running multiple resource
        demanding tests in parallel.
      5. enable `--verbose` to be repeated to elevate verbosity and print more info to stdout
        when a test or a server starts.

      Increase threshold for flaky cache reclaim test (#12004) · f263b6da
      Oran Agra authored
      This test produces 1GB of data and moves it around, and was expecting less
      than 500kb to be present in the system page cache.
      It sometimes fails with up to some 6mb in the page cache (0 in the actual RDB files),
      increasing the threshold. It looks like some background tasks in the container are
      occupying the page cache.
      
      It is safe to ignore the above since we also explicitly check the pages of our dump.rdb
      are not cached (matching `vmtouch -v` to `0%`).
      An additional fix is to match ` 0%` (add space), so that we don't successfully match `10%`.

      Add reply_schema to command json files (internal for now) (#10273) · 4ba47d2d
      guybe7 authored
      Work in progress towards implementing a reply schema as part of COMMAND DOCS, see #9845
      Since ironing the details of the reply schema of each and every command can take a long time, we
      would like to merge this PR when the infrastructure is ready, and let this mature in the unstable branch.
      Meanwhile the changes of this PR are internal, they are part of the repo, but do not affect the produced build.
      
      ### Background
      In #9656 we add a lot of information about Redis commands, but we are missing information about the replies
      
      ### Motivation
      1. Documentation. This is the primary goal.
      2. It should be possible, based on the output of COMMAND, to be able to generate client code in typed
        languages. In order to do that, we need Redis to tell us, in detail, what each reply looks like.
      3. We would like to build a fuzzer that verifies the reply structure (for now we use the existing
        testsuite, see the "Testing" section)
      
      ### Schema
      The idea is to supply some sort of schema for the various replies of each command.
      The schema will describe the conceptual structure of the reply (for generated clients), as defined in RESP3.
      Note that the reply structure itself may change, depending on the arguments (e.g. `XINFO STREAM`, with
      and without the `FULL` modifier)
      We decided to use the standard json-schema (see https://json-schema.org/) as the reply-schema.
      
      Example for `BZPOPMIN`:
      ```
      "reply_schema": {
          "oneOf": [
              {
                  "description": "Timeout reached and no elements were popped.",
                  "type": "null"
              },
              {
                  "description": "The keyname, popped member, and its score.",
                  "type": "array",
                  "minItems": 3,
                  "maxItems": 3,
                  "items": [
                      {
                          "description": "Keyname",
                          "type": "string"
                      },
                      {
                          "description": "Member",
                          "type": "string"
                      },
                      {
                          "description": "Score",
                          "type": "number"
                      }
                  ]
              }
          ]
      }
      ```
      
      #### Notes
      1.  It is ok that some commands' reply structure depends on the arguments and it's the caller's responsibility
        to know which is the relevant one. this comes after looking at other request-reply systems like OpenAPI,
        where the reply schema can also be oneOf and the caller is responsible to know which schema is the relevant one.
      2. The reply schemas will describe RESP3 replies only. even though RESP3 is structured, we want to use reply
        schema for documentation (and possibly to create a fuzzer that validates the replies)
      3. For documentation, the description field will include an explanation of the scenario in which the reply is sent,
        including any relation to arguments. for example, for `ZRANGE`'s two schemas we will need to state that one
        is with `WITHSCORES` and the other is without.
      4. For documentation, there will be another optional field "notes" in which we will add a short description of
        the representation in RESP2, in case it's not trivial (RESP3's `ZRANGE`'s nested array vs. RESP2's flat
        array, for example)
      
      Given the above:
      1. We can generate the "return" section of all commands in [redis-doc](https://redis.io/commands/)
        (given that "description" and "notes" are comprehensive enough)
      2. We can generate a client in a strongly typed language (but the return type could be a conceptual
        `union` and the caller needs to know which schema is relevant). see the section below for RESP2 support.
      3. We can create a fuzzer for RESP3.
      
      ### Limitations (because we are using the standard json-schema)
      The problem is that Redis' replies are more diverse than what the json format allows. This means that,
      when we convert the reply to a json (in order to validate the schema against it), we lose information (see
      the "Testing" section below).
      The other option would have been to extend the standard json-schema (and json format) to include stuff
      like sets, bulk-strings, error-string, etc. but that would mean also extending the schema-validator - and that
      seemed like too much work, so we decided to compromise.
      
      Examples:
      1. We cannot tell the difference between an "array" and a "set"
      2. We cannot tell the difference between simple-string and bulk-string
      3. we cannot verify true uniqueness of items in commands like ZRANGE: json-schema doesn't cover the
        case of two identical members with different scores (e.g. `[["m1",6],["m1",7]]`) because `uniqueItems`
        compares (member,score) tuples and not just the member name. 
      
      ### Testing
      This commit includes some changes inside Redis in order to verify the schemas (existing and future ones)
      are indeed correct (i.e. describe the actual response of Redis).
      To do that, we added a debugging feature to Redis that causes it to produce a log of all the commands
      it executed and their replies.
      For that, Redis needs to be compiled with `-DLOG_REQ_RES` and run with
      `--reg-res-logfile <file> --client-default-resp 3` (the testsuite already does that if you run it with
      `--log-req-res --force-resp3`)
      You should run the testsuite with the above args (and `--dont-clean`) in order to make Redis generate
      `.reqres` files (same dir as the `stdout` files) which contain request-response pairs.
      These files are later on processed by `./utils/req-res-log-validator.py` which does:
      1. Goes over req-res files, generated by redis-servers, spawned by the testsuite (see logreqres.c)
      2. For each request-response pair, it validates the response against the request's reply_schema
        (obtained from the extended COMMAND DOCS)
      5. In order to get good coverage of the Redis commands, and all their different replies, we chose to use
        the existing redis test suite, rather than attempt to write a fuzzer.
      
      #### Notes about RESP2
      1. We will not be able to use the testing tool to verify RESP2 replies (we are ok with that, it's time to
        accept RESP3 as the future RESP)
      2. Since the majority of the test suite is using RESP2, and we want the server to reply with RESP3
        so that we can validate it, we will need to know how to convert the actual reply to the one expected.
         - number and boolean are always strings in RESP2 so the conversion is easy
         - objects (maps) are always a flat array in RESP2
         - others (nested array in RESP3's `ZRANGE` and others) will need some special per-command
           handling (so the client will not be totally auto-generated)
      
      Example for ZRANGE:
      ```
      "reply_schema": {
          "anyOf": [
              {
                  "description": "A list of member elements",
                  "type": "array",
                  "uniqueItems": true,
                  "items": {
                      "type": "string"
                  }
              },
              {
                  "description": "Members and their scores. Returned in case `WITHSCORES` was used.",
                  "notes": "In RESP2 this is returned as a flat array",
                  "type": "array",
                  "uniqueItems": true,
                  "items": {
                      "type": "array",
                      "minItems": 2,

      ```
      
      ### Other changes
      1. Some tests that behave differently depending on the RESP are now being tested for both RESP,
        regardless of the special log-req-res mode ("Pub/Sub PING" for example)
      2. Update the history field of CLIENT LIST
      3. Added basic tests for commands that were not covered at all by the testsuite
      
      ### TODO
      
      - [x] (maybe a different PR) add a "condition" field to anyOf/oneOf schemas that refers to args. e.g.
        when `SET` return NULL, the condition is `arguments.get||arguments.condition`, for `OK` the condition
        is `!arguments.get`, and for `string` the condition is `arguments.get` - https://github.com/redis/redis/issues/11896
      - [x] (maybe a different PR) also run `runtest-cluster` in the req-res logging mode
      - [x] add the new tests to GH actions (i.e. compile with `-DLOG_REQ_RES`, run the tests, and run the validator)
      - [x] (maybe a different PR) figure out a way to warn about (sub)schemas that are uncovered by the output
        of the tests - https://github.com/redis/redis/issues/11897
      - [x] (probably a separate PR) add all missing schemas
      - [x] check why "SDOWN is triggered by misconfigured instance replying with errors" fails with --log-req-res
      - [x] move the response transformers to their own file (run both regular, cluster, and sentinel tests - need to
        fight with the tcl including mechanism a bit)
      - [x] issue: module API - https://github.com/redis/redis/issues/11898
      - [x] (probably a separate PR): improve schemas: add `required` to `object`s - https://github.com/redis/redis/issues/11899

      Stablize page reclaim CI test (#11818) · 3ac83577
      Oran Agra authored
      stabilize the test introduced in #11248
      * remove random aspect of the test by using DEBUG POPULATE instead of redis-benchmark
      * disable rdbcompression, so that the rdb file is always about 1GB.
      
      when fadvise was disabled, i get about 1GB in the page cace
      when enabled i get less than 200KB
      so for now, i'll keep the 500kb threshold.

      Reclaim page cache of RDB file (#11248) · 7dae142a
      Tian authored
      # Background
      The RDB file is usually generated and used once and seldom used again, but the content would reside in page cache until OS evicts it. A potential problem is that once the free memory exhausts, the OS have to reclaim some memory from page cache or swap anonymous page out, which may result in a jitters to the Redis service.
      
      Supposing an exact scenario, a high-capacity machine hosts many redis instances, and we're upgrading the Redis together. The page cache in host machine increases as RDBs are generated. Once the free memory drop into low watermark(which is more likely to happen in older Linux kernel like 3.10, before [watermark_scale_factor](https://lore.kernel.org/lkml/1455813719-2395-1-git-send-email-hannes@cmpxchg.org/) is introduced, the `low watermark` is linear to `min watermark`, and there'is not too much buffer space for `kswapd` to be wake up to reclaim memory), a `direct reclaim` happens, which means the process would stall to wait for memory allocation.
      
      # What the PR does
      The PR introduces a capability to reclaim the cache when the RDB is operated. Generally there're two cases, read and write the RDB. For read it's a little messy to address the incremental reclaim, so the reclaim is done in one go in background after the load is finished to avoid blocking the work thread. For write, incremental reclaim amortizes the work of reclaim so no need to put it into background, and the peak watermark of cache can be reduced in this way.
      
      Two cases are addresses specially, replication and restart, for both of which the cache is leveraged to speed up the processing, so the reclaim is postponed to a right time. To do this, a flag is added to`rdbSave` and `rdbLoad` to control whether the cache need to be kept, with the default value false.
      
      # Something deserve noting
      1. Though `posix_fadvise` is the POSIX standard, but only few platform support it, e.g. Linux, FreeBSD 10.0.
      2. In Linux `posix_fadvise` only take effect on writeback-ed pages, so a `sync`(or `fsync`, `fdatasync`) is needed to flush the dirty page before `posix_fadvise` if we reclaim write cache.
      
      # About test
      A unit test is added to verify the effect of `posix_fadvise`.
      In integration test overall cache increase is checked, as well as the cache backed by RDB as a specific TCL test is executed in isolated Github action job.

      Fix sentinel update loglevel tls test (#11528) · 0f857131
      Binbin authored
      Apparently we used to set `loglevel debug` for tls in spawn_instance.
      I.e. cluster and sentinel tests used to run with debug logging, only when tls mode was enabled.
      this was probably a leftover from when creating the tls mode tests.
      it cause a new test created for #11214 to fail in tls mode.
      
      At the same time, in order to better distinguish the tests, change the
      name of `test-centos7-tls` to `test-centos7-tls-module`, change the name
      of `test-centos7-tls-no-tls` to `test-centos7-tls-module-no-tls`.
      
      Note that in `test-centos7-tls-module`, we did not pass `--tls-module`
      in sentinel test because it is not supported, see 4faddf18
      
      , added in #9320.
      So only `test-ubuntu-tls` fails in daily CI.

      Upgrade vmactions/freebsd-vm to the latest version (0.3.0) can work.
      I've tested it, but don't know why, but first let's fix it.

      Build TLS as a loadable module · 4faddf18
      Oran Agra authored
      
      
      * Support BUILD_TLS=module to be loaded as a module via config file or
        command line. e.g. redis-server --loadmodule redis-tls.so
      * Updates to redismodule.h to allow it to be used side by side with
        server.h by defining REDISMODULE_CORE_MODULE
      * Changes to server.h, redismodule.h and module.c to avoid repeated
        type declarations (gcc 4.8 doesn't like these)
      * Add a mechanism for non-ABI neutral modules (ones who include
        server.h) to refuse loading if they detect not being built together with
        redis (release.c)
      * Fix wrong signature of RedisModuleDefragFunc, this could break
        compilation of a module, but not the ABI
      * Move initialization of listeners in server.c to be after loading
        the modules
      * Config TLS after initialization of listeners
      * Init cluster after initialization of listeners
      * Add TLS module to CI
      * Fix a test suite race conditions:
        Now that the listeners are initialized later, it's not sufficient to
        wait for the PID message in the log, we need to wait for the "Server
        Initialized" message.
      * Fix issues with moduleconfigs test as a result from start_server
        waiting for "Server Initialized"
      * Fix issues with modules/infra test as a result of an additional module
        present
      
      Notes about Sentinel:
      Sentinel can't really rely on the tls module, since it uses hiredis to
      initiate connections and depends on OpenSSL (won't be able to use any
      other connection modules for that), so it was decided that when TLS is
      built as a module, sentinel does not support TLS at all.
      This means that it keeps using redis_tls_ctx and redis_tls_client_ctx directly.
      
      Example code of config in redis-tls.so(may be use in the future):
      RedisModuleString *tls_cfg = NULL;
      
      void tlsInfo(RedisModuleInfoCtx *ctx, int for_crash_report) {
          UNUSED(for_crash_report);
          RedisModule_InfoAddSection(ctx, "");
          RedisModule_InfoAddFieldLongLong(ctx, "var", 42);
      }
      
      int tlsCommand(RedisModuleCtx *ctx, RedisModuleString **argv, int argc)
      {
          if (argc != 2) return RedisModule_WrongArity(ctx);
          return RedisModule_ReplyWithString(ctx, argv[1]);
      }
      
      RedisModuleString *getStringConfigCommand(const char *name, void *privdata) {
          REDISMODULE_NOT_USED(name);
          REDISMODULE_NOT_USED(privdata);
          return tls_cfg;
      }
      
      int setStringConfigCommand(const char *name, RedisModuleString *new, void *privdata, RedisModuleString **err) {
          REDISMODULE_NOT_USED(name);
          REDISMODULE_NOT_USED(err);
          REDISMODULE_NOT_USED(privdata);
          if (tls_cfg) RedisModule_FreeString(NULL, tls_cfg);
          RedisModule_RetainString(NULL, new);
          tls_cfg = new;
          return REDISMODULE_OK;
      }
      
      int RedisModule_OnLoad(void *ctx, RedisModuleString **argv, int argc)
      {
          ....
          if (RedisModule_CreateCommand(ctx,"tls",tlsCommand,"",0,0,0) == REDISMODULE_ERR)
              return REDISMODULE_ERR;
      
          if (RedisModule_RegisterStringConfig(ctx, "cfg", "", REDISMODULE_CONFIG_DEFAULT, getStringConfigCommand, setStringConfigCommand, NULL, NULL) == REDISMODULE_ERR)
              return REDISMODULE_ERR;
      
          if (RedisModule_LoadConfigs(ctx) == REDISMODULE_ERR) {
              if (tls_cfg) {
                  RedisModule_FreeString(ctx, tls_cfg);
                  tls_cfg = NULL;
              }
              return REDISMODULE_ERR;
          }
          ...
      }

      Fix Lua C API violation on lua msgpack lib. (#9832) · a8c1253b
      Meir Shpilraien (Spielrein) authored
      msgpack lib missed using lua_checkstack and so on rare
      cases overflow the stack by at most 2 elements. This is a
      violation of the Lua C API. Notice that Lua allocates
      additional 5 more elements on top of lua->stack_last
      so Redis does not access an invalid memory. But it is an
      API violation and we should avoid it.
      
      This PR also added a new Lua compilation option. The new
      option can be enable using environment variable called
      LUA_DEBUG. If set to `yes` (by default `no`), Lua will be
      compiled without optimizations and with debug symbols (`-O0 -g`).
      In addition, in this new mode, Lua will be compiled with the
      `-DLUA_USE_APICHECK` flag that enables extended Lua C API
      validations.
      
      In addition, set LUA_DEBUG=yes on daily valgrind flow so we
      will be able to catch Lua C API violations in the future.
