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:
```
src/jemalloc.c:1028:7: warning: suspicious concatenation of string literals in an array initialization; did you mean to separate the elements with a comma? [-Wstring-concatenation]
"/etc/malloc.conf",
^
src/jemalloc.c:1027:3: note: place parentheses around the string literal to silence warning
"\"name\" of the file referenced by the symbolic link named "
^
```
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:
```
In file included from quicklist.c:36:
./config.h:319:76: warning: attribute declaration must precede definition [-Wignored-attributes]
char *strcat(char *restrict dest, const char *restrict src) __attribute__((deprecated("please avoid use of unsafe C functions. prefer use of redis_strlcat instead")));
```
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
WARNING:
```
networking.c: In function ‘addReplyDouble.part.0’:
networking.c:876:21: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=]
876 | dbuf[start] = '$';
| ^
networking.c:868:14: note: at offset -5 into destination object ‘dbuf’ of size 5152
868 | char dbuf[MAX_LONG_DOUBLE_CHARS+32];
| ^
networking.c:876:21: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=]
876 | dbuf[start] = '$';
| ^
networking.c:868:14: note: at offset -6 into destination object ‘dbuf’ of size 5152
868 | char dbuf[MAX_LONG_DOUBLE_CHARS+32];
```
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;
4) redis-cli.c & redis-benchmark.c
COMPILER: clang-14 with FORTIFY_SOURCE
WARNING:
```
redis-benchmark.c:1621:2: warning: embedding a directive within macro arguments has undefined behavior [-Wembedded-directive] #ifdef USE_OPENSSL
redis-cli.c:3015:2: warning: embedding a directive within macro arguments has undefined behavior [-Wembedded-directive] #ifdef USE_OPENSSL
```
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()`.
5) server.c
COMPILER: gcc-13 with FORTIFY_SOURCE
WARNING:
```
In function 'lookupCommandLogic',
inlined from 'lookupCommandBySdsLogic' at server.c:3139:32:
server.c:3102:66: error: '*(robj **)argv' may be used uninitialized [-Werror=maybe-uninitialized]
3102 | struct redisCommand *base_cmd = dictFetchValue(commands, argv[0]->ptr);
| ~~~~^~~
```
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.
6) sha1.c
COMPILER: gcc-12
WARNING:
```
In function ‘SHA1Update’,
inlined from ‘SHA1Final’ at sha1.c:195:5:
sha1.c:152:13: warning: ‘SHA1Transform’ reading 64 bytes from a region of size 0 [-Wstringop-overread]
152 | SHA1Transform(context->state, &data[i]);
| ^
sha1.c:152:13: note: referencing argument 2 of type ‘const unsigned char[64]’
sha1.c: In function ‘SHA1Final’:
sha1.c:56:6: note: in a call to function ‘SHA1Transform’
56 | void SHA1Transform(uint32_t state[5], const unsigned char buffer[64])
| ^
In function ‘SHA1Update’,
inlined from ‘SHA1Final’ at sha1.c:198:9:
sha1.c:152:13: warning: ‘SHA1Transform’ reading 64 bytes from a region of size 0 [-Wstringop-overread]
152 | SHA1Transform(context->state, &data[i]);
| ^
sha1.c:152:13: note: referencing argument 2 of type ‘const unsigned char[64]’

sha1.c:56:6: note: in a call to function ‘SHA1Transform’
56 | void SHA1Transform(uint32_t state[5], const unsigned char buffer[64])
```
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
COMPILER: GCC-12
WARNING:
```
In function ‘memset’,
inlined from ‘moduleCreateContext’ at module.c:877:5,
inlined from ‘RM_GetDetachedThreadSafeContext’ at module.c:8410:5:
/usr/include/x86_64-linux-gnu/bits/string_fortified.h:59:10: warning: ‘__builtin_memset’ writing 104 bytes into a region of size 0 overflows the destination [-Wstringop-overflow=]
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.

testsuite (#12023)
In daily.yml, if the input suggests we don't run the full testsuite,
do not pass --fail-commands-not-all-hit to the validator.
This fixes the first point in #11954. Credit goes to the comment
on the open issue for GH actions: actions/runner#409
Also improve prints to show the dispatch arguments in every job.

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.

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%`.

these latency threshold errors prevent the schema validation from running.

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,
"maxItems": 2,
"items": [
{
"description": "Member",
"type": "string"
},
{
"description": "Score",
"type": "number"
}
]
}
}
]
}
```
### 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

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.

the new test is incompatible with valgrind.
added a new `--valgrind` argument to `redis-server tests` mode,
which will cause that test to be skipped..

# 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.

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 4faddf1, added in #9320.
So only `test-ubuntu-tls` fails in daily CI.

* 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;
}
...

* missing parenthesis meant that the ubuntu and centos jobs were not
skipped
* the recently divided freebsd, macos, and valgrind jobs, which are now
split into distict jobs for redis, modules, sentinel, cluster. were
all executed, producing a build, but not running anything.
now they're filtered at the job level
* iothreads was missing from the skip list defaults, so was not skipped
|
| |
|
|
| |
this should aid find the CI issues with freebsd and macos runs, and also
get faster results from valgrind and tls
|
| | |
|
| | |
|
| |
|
|
| |
sometimes you just wanna run one test on one system (e.g. memefficiency
on macos), so you want all other tests to be skipped
|
| | |
|
| |
|
| |
keep the push triggers for all repos, but run the scheduled ones only on redis/redis

To avoid data loss, this commit adds a grace period for lagging replicas to
catch up the replication offset.
Done:
* Wait for replicas when shutdown is triggered by SIGTERM and SIGINT.
* Wait for replicas when shutdown is triggered by the SHUTDOWN command. A new
blocked client type BLOCKED_SHUTDOWN is introduced, allowing multiple clients
to call SHUTDOWN in parallel.
Note that they don't expect a response unless an error happens and shutdown is aborted.
* Log warning for each replica lagging behind when finishing shutdown.
* CLIENT_PAUSE_WRITE while waiting for replicas.
* Configurable grace period 'shutdown-timeout' in seconds (default 10).
* New flags for the SHUTDOWN command:
- NOW disables the grace period for lagging replicas.
- FORCE ignores errors writing the RDB or AOF files which would normally
prevent a shutdown.
- ABORT cancels ongoing shutdown. Can't be combined with other flags.
* New field in the output of the INFO command: 'shutdown_in_milliseconds'. The
value is the remaining maximum time to wait for lagging replicas before
finishing the shutdown. This field is present in the Server section **only**
during shutdown.
Not directly related:
* When shutting down, if there is an AOF saving child, it is killed **even** if AOF
is disabled. This can happen if BGREWRITEAOF is used when AOF is off.
* Client pause now has end time and type (WRITE or ALL) per purpose. The
different pause purposes are *CLIENT PAUSE command*, *failover* and
*shutdown*. If clients are unpaused for one purpose, it doesn't affect client
pause for other purposes. For example, the CLIENT UNPAUSE command doesn't
affect client pause initiated by the failover or shutdown procedures. A completed
failover or a failed shutdown doesn't unpause clients paused by the CLIENT
PAUSE command.
Notes:
* DEBUG RESTART doesn't wait for replicas.
* We already have a warning logged when a replica disconnects. This means that
if any replica connection is lost during the shutdown, it is either logged as
disconnected or as lagging at the time of exit.

- add needs:debug flag for some tests
- disable "save" in external tests (speedup?)
- use debug_digest proc instead of debug command directly so it can be skipped
- use OBJECT ENCODING instead of DEBUG OBJECT to get encoding
- add a proc for OBJECT REFCOUNT so it can be skipped
- move a bunch of tests in latency_monitor tests to happen later so that latency monitor has some values in it
- add missing close_replication_stream calls
- make sure to close the temp client if DEBUG LOG fails

Block sensitive configs and commands by default.
* `enable-protected-configs` - block modification of configs with the new `PROTECTED_CONFIG` flag.
Currently we add this flag to `dbfilename`, and `dir` configs,
all of which are non-mutable configs that can set a file redis will write to.
* `enable-debug-command` - block the `DEBUG` command
* `enable-module-command` - block the `MODULE` command
These have a default value set to `no`, so that these features are not
exposed by default to client connections, and can only be set by modifying the config file.
Users can change each of these to either `yes` (allow all access), or `local` (allow access from
local TCP connections and unix domain connections)
Note that this is a **breaking change** (specifically the part about MODULE command being disabled by default).
I.e. we don't consider DEBUG command being blocked as an issue (people shouldn't have been using it),
and the few configs we protected are unlikely to have been set at runtime anyway.
On the other hand, it's likely to assume some users who use modules, load them from the config file anyway.
Note that's the whole point of this PR, for redis to be more secure by default and reduce the attack surface on
innocent users, so secure defaults will necessarily mean a breaking change.

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.

specifically the ziplist and listpack unit tests and benchmarks run for too long with address sanitizer and --accurate
|
| |
|
| |
So that we can print server log on test failure.
|
| |
|
|
|
|
| |
Add --accurate to unit tests (new feature recently added)
Add --no-latency to valgrind run (was present only for modules)
add --no-latency to macos and freebsd runs (was not present for modules)
add --timeout to freebsd (same one we have for valgrind)

- Added sanitizer support. `address`, `undefined` and `thread` sanitizers are available.
- To build Redis with desired sanitizer : `make SANITIZER=undefined`
- There were some sanitizer findings, cleaned up codebase
- Added tests with address and undefined behavior sanitizers to daily CI.
- Added tests with address sanitizer to the per-PR CI (smoke out mem leaks sooner).
Basically, there are three types of issues :
**1- Unaligned load/store** : Most probably, this issue may cause a crash on a platform that
does not support unaligned access. Redis does unaligned access only on supported platforms.
**2- Signed integer overflow.** Although, signed overflow issue can be problematic time to time
and change how compiler generates code, current findings mostly about signed shift or simple
addition overflow. For most platforms Redis can be compiled for, this wouldn't cause any issue
as far as I can tell (checked generated code on godbolt.org).
**3 -Minor leak** (redis-cli), **use-after-free**(just before calling exit());
UB means nothing guaranteed and risky to reason about program behavior but I don't think any
of the fixes here worth backporting. As sanitizers are now part of the CI, preventing new issues
will be the real benefit.

On test failure store the external redis server logs as CI artifacts so we can review them.
Write test name to server log for external server tests.
This is attempted and silently failed in case external server doesn't support it.
Note that in non-external server mode we use a more robust method of writing to the log which doesn't depend on the
server actually running/working. This isn't possible for externl servers and required for some complex tests which are
skipped in external mode anyway.
Cleanup: remove dup code.

First, avoid using --accurate on the freebsd CI, we only care about
systematic issues there due to being different platform, but not
accuracy
Secondly, when looking at the test which timed out it seems silly and
outdated:
- it used KEYS to attempt to trigger lazy expiry, but KEYS doesn't do
that anymore.
- it used some hard coded sleeps rather than waiting for things to
happen and exiting ASAP
|
| |
|
|
|
|
|
| |
We saw some tests sporadically time out on valgrind (namely the ones
from #9323).
Increasing valgrind timeout from 20 mins to 40 mins in CI.
And fixing an outdated help message.
|
| |
|
|
|
|
| |
In both tests, "diskless loading short read" and "diskless loading short read with module",
the timeout of waiting for the replica to respond to a short read and log it, is too short.
Also, add --dump-logs in runtest-moduleapi for valgrind runs.

Redis lists are stored in quicklist, which is currently a linked list of ziplists.
Ziplists are limited to storing elements no larger than 4GB, so when bigger
items are added they're getting truncated.
This PR changes quicklists so that they're capable of storing large items
in quicklist nodes that are plain string buffers rather than ziplist.
As part of the PR there were few other changes in redis:
1. new DEBUG sub-commands:
- QUICKLIST-PACKED-THRESHOLD - set the threshold of for the node type to
be plan or ziplist. default (1GB)
- QUICKLIST <key> - Shows low level info about the quicklist encoding of <key>
2. rdb format change:
- A new type was added - RDB_TYPE_LIST_QUICKLIST_2 .
- container type (packed / plain) was added to the beginning of the rdb object
(before the actual node list).
3. testing:
- Tests that requires over 100MB will be by default skipped. a new flag was
added to 'runtest' to run the large memory tests (not used by default)

Making sure Redis builds properly on older compiler is important given the wide range of systems it is built for. So far Ubuntu 16.04 has been used for this purpose, but as it's getting phased out we'll move to `oldoldstable` Debian as an "old system" precursor.

GETBIT/SETBIT/BITFIELD/BITCOUNT,BITPOS may overflow (see CVE-2021-32761) (#9191)
GETBIT, SETBIT may access wrong address because of wrap.
BITCOUNT and BITPOS may return wrapped results.
BITFIELD may access the wrong address but also allocate insufficient memory and segfault (see CVE-2021-32761).
This commit uses `uint64_t` or `long long` instead of `size_t`.
related https://github.com/redis/redis/pull/8096
At 32bit platform:
> setbit bit 4294967295 1
(integer) 0
> config set proto-max-bulk-len 536870913
OK
> append bit "\xFF"
(integer) 536870913
> getbit bit 4294967296
(integer) 0
When the bit index is larger than 4294967295, size_t can't hold bit index. In the past, `proto-max-bulk-len` is limit to 536870912, so there is no problem.
After this commit, bit position is stored in `uint64_t` or `long long`. So when `proto-max-bulk-len > 536870912`, 32bit platforms can still be correct.
For 64bit platform, this problem still exists. The major reason is bit pos 8 times of byte pos. When proto-max-bulk-len is very larger, bit pos may overflow.
But at 64bit platform, we don't have so long string. So this bug may never happen.
Additionally this commit add a test cost `512MB` memory which is tag as `large-memory`. Make freebsd ci and valgrind ci ignore this test.
