- 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
When redis-cli received ASK, it used string matching wrong and didn't
handle it.
When we access a slot which is in migrating state, it maybe
return ASK. After redirect to the new node, we need send ASKING
command before retry the command. In this PR after redis-cli receives
ASK, we send a ASKING command before send the origin command
after reconnecting.
Other changes:
* Make redis-cli -u and -c (unix socket and cluster mode) incompatible
with one another.
* When send command fails, we avoid the 2nd reconnect retry and just
print the error info. Users will decide how to do next.
See #9277.
* Add a test faking two redis nodes in TCL to just send ASK and OK in
redis protocol to test ASK behavior.

In some cases large replies on slow systems may only be partially read
by the test suite, resulting with parsing errors.
This fix is still timing sensitive but should greatly reduce the chances
of this happening.
1. redis-cli can output --rdb data to stdout
but redis-cli also write some messages to stdout which will mess up the rdb.
2. Make redis-cli flush stdout when printing a reply
This was needed in order to fix a hung in redis-cli test that uses
--replica.
Note that printf does flush when there's a newline, but fwrite does not.
3. fix the redis-cli --replica test which used to pass previously
because it didn't really care what it read, and because redis-cli
used printf to print these other things to stdout.
4. improve redis-cli --replica test to run with both diskless and disk-based.

This commit revives the improves the ability to run the test suite against
external servers, instead of launching and managing `redis-server` processes as
part of the test fixture.
This capability existed in the past, using the `--host` and `--port` options.
However, it was quite limited and mostly useful when running a specific tests.
Attempting to run larger chunks of the test suite experienced many issues:
* Many tests depend on being able to start and control `redis-server` themselves,
and there's no clear distinction between external server compatible and other
tests.
* Cluster mode is not supported (resulting with `CROSSSLOT` errors).
This PR cleans up many things and makes it possible to run the entire test suite
against an external server. It also provides more fine grained controls to
handle cases where the external server supports a subset of the Redis commands,
limited number of databases, cluster mode, etc.
The tests directory now contains a `README.md` file that describes how this
works.
This commit also includes additional cleanups and fixes:
* Tests can now be tagged.
* Tag-based selection is now unified across `start_server`, `tags` and `test`.
* More information is provided about skipped or ignored tests.
* Repeated patterns in tests have been extracted to common procedures, both at a
global level and on a per-test file basis.
* Cleaned up some cases where test setup was based on a previous test executing
(a major anti-pattern that repeats itself in many places).
* Cleaned up some cases where test teardown was not part of a test (in the
future we should have dedicated teardown code that executes even when tests
fail).
* Fixed some tests that were flaky running on external servers.
* 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
This re-implements the redis-cli --pipe test so it no longer depends on a close feature available only in TCL 8.6.
Basically what this test does is run redis-cli --pipe, generates a bunch of commands and pipes them through redis-cli, and inspects the result in both Redis and the redis-cli output.
To do that, we need to close stdin for redis-cli to indicate we're done so it can flush its buffers and exit. TCL has bi-directional channels can only offers a way to "one-way close" a channel with TCL 8.6. To work around that, we now generate the commands into a file and feed that file to redis-cli directly.
As we're writing to an actual file, the number of commands is now reduced.
interestingly the latency monitor test fails because valgrind is slow
enough so that the time inside PEXPIREAT command from the moment of
the first mstime() call to get the basetime until checkAlreadyExpired
calls mstime() again is more than 1ms, and that test was too sensitive.
using this opportunity to speed up the test (unrelated to the failure)
the fix is just the longer time passed to PEXPIRE.
* Tests: fix and reintroduce redis-cli tests.
These tests have been broken and disabled for 10 years now!
* TLS: add remaining redis-cli support.
This adds support for the redis-cli --pipe, --rdb and --replica options
previously unsupported in --tls mode.
* Fix writeConn().
* 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.
