When redis-check-aof finds an error, it prints the line number for faster troubleshooting.
(cherry picked from commit 761d7d27711edfbf737def41ff28f5b325fb16c8)
In github actions CI with valgrind, i saw that even the fast replica
(one that wasn't paused), didn't get to complete the replication fast
enough, and ended up getting disconnected by timeout.
Additionally, due to a typo in uname, we didn't get to actually run the
CPU efficiency part of the test.
Starting redis 6.0 (part of the TLS feature), diskless master uses pipe from the fork
child so that the parent is the one sending data to the replicas.
This mechanism has an issue in which a hung replica will cause the master to wait
for it to read the data sent to it forever, thus preventing the fork child from terminating
and preventing the creations of any other forks.
This PR adds a timeout mechanism, much like the ACK-based timeout,
we disconnect replicas that aren't reading the RDB file fast enough.
Another test race condition in the macos tests.
the test was waiting for PINGs to be generated and put on the replication stream,
but waiting for 1 or 2 seconds doesn't really guarantee that.
then the test that expected 6 full syncs, found only 4
the corrupt-dump-fuzzer test found a case where an access to a corrupt
stream would have caused accessing to uninitialized memory.
now it'll panic instead.
The issue was that there was a stream that says it has more than 0
records, but looking for the max ID came back empty handed.
p.s. when sanitize-dump-payload is used, this corruption is detected,
and the RESTORE command is gracefully rejected.
Since redis 6.2, redis immediately tries to connect to the master, not
waiting for replication cron.
in the slow freebsd CI, this test failed and master_link_status was
already "up" when INFO was called.
* The `redis-cli --scan` output should honor output mode (set explicitly or implicitly), and quote key names when not in raw mode.
* Technically this is a breaking change, but it should be very minor since raw mode is by default on for non-tty output.
* It should only affect TTY output (human users) or non-tty output if `--no-raw` is specified.
* Added `--quoted-input` option to treat all arguments as potentially quoted strings.
* Added `--quoted-pattern` option to accept a potentially quoted pattern.
Unquoting is applied to potentially quoted input only if single or double quotes are used.
Fixes#8561, #8563
When sanitizing the stream listpack, we need to count the deleted records too.
otherwise the last line that checks the next pointer fails.
Add test to cover that state in the stream tests.
* Remove linux/version.h dependency.
This introduces unnecessary dependencies, and generally not a good idea
as the platform we build on may be different than the platform we run
on.
To determine if sync_file_range exists we can simply rely on header file
hints.
* Fix setproctitle() on libmusl.
The previous ifdef checks were a bit too strict for no apparent
reason.
* Fix tests failure on Linux with no backtrace.
* Add alpine daily CI job.
* Adding current_save_keys_total and current_save_keys_processed info fields.
Present in replication, BGSAVE and AOFRW.
* Changing RM_SendChildCOWInfo() to RM_SendChildHeartbeat(double progress)
* Adding new info field current_fork_perc. Present in Replication, BGSAVE, AOFRW,
and module forks.
* Add bash temporarily to allow sentinel fd leaks test to run.
* Use vmactions-freebsd rdist sync to work around bind permission denied
and slow execution issues.
* Upgrade to tcl8.6 to be aligned with latest Ubuntu envs.
* Concat all command executions to avoid ignoring failures.
* Skip intensive fuzzer on FreeBSD. For some yet unknown reason, generate_fuzzy_traffic_on_key causes TCL to significantly bloat on FreeBSD resulting with out of memory.
* 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.
This commit introduces two new command and two options for an existing command
GETEX <key> [PERSIST][EX seconds][PX milliseconds] [EXAT seconds-timestamp]
[PXAT milliseconds-timestamp]
The getexCommand() function implements extended options and variants of the GET
command. Unlike GET command this command is not read-only. Only one of the options
can be used at a given time.
1. PERSIST removes any TTL associated with the key.
2. EX Set expiry TTL in seconds.
3. PX Set expiry TTL in milliseconds.
4. EXAT Same like EX instead of specifying the number of seconds representing the
TTL (time to live), it takes an absolute Unix timestamp
5. PXAT Same like PX instead of specifying the number of milliseconds representing the
TTL (time to live), it takes an absolute Unix timestamp
Command would return either the bulk string, error or nil.
GETDEL <key>
Would delete the key after getting.
SET key value [NX] [XX] [KEEPTTL] [GET] [EX <seconds>] [PX <milliseconds>]
[EXAT <seconds-timestamp>][PXAT <milliseconds-timestamp>]
Two new options added here are EXAT and PXAT
Key implementation notes
- `SET` with `PX/EX/EXAT/PXAT` is always translated to `PXAT` in `AOF`. When relative time is
specified (`PX/EX`), replication will always use `PX`.
- `setexCommand` and `psetexCommand` would no longer need translation in `feedAppendOnlyFile`
as they are modified to invoke `setGenericCommand ` with appropriate flags which will take care of
correct AOF translation.
- `GETEX` without any optional argument behaves like `GET`.
- `GETEX` command is never propagated, It is either propagated as `PEXPIRE[AT], or PERSIST`.
- `GETDEL` command is propagated as `DEL`
- Combined the validation for `SET` and `GETEX` arguments.
- Test cases to validate AOF/Replication propagation
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.
- the last COW report wasn't always read from the pipe
(receiveLastChildInfo wasn't used)
- but in fact, there's no reason we won't always try to drain that pipe
so i'm unifying receiveLastChildInfo with receiveChildInfo
- adjust threshold of the COW test when run in accurate mode
- add some prints in case this test fails again
- fix indentation, page size, and PID! in MacOS proc info
p.s. it seems that pri_pages_dirtied is always 0
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
If RESTORE passes successfully with full sanitization, we can't affort
to crash later on assertion due to duplicate records in a hash when
converting it form ziplist to dict.
This means that when doing full sanitization, we must make sure there
are no duplicate records in any of the collections.
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
