Force INFO used_memory_peak to match peak memory
-
antirez authored
This is still code to rework in order to use agreement to obtain a new configEpoch when a slot is migrated, however this commit handles the special case that happens when the nodes are just started and everybody has a configEpoch of 0. In this special condition to have the maximum configEpoch is not enough as the special epoch 0 is not unique (all the others are). This does not fixes the intrinsic race condition of a failover happening while we are resharding, that will be addressed later.

used_memory_peak only updates in serverCron every server.hz, but Redis can use more memory and a user can request memory INFO before used_memory_peak gets updated in the next cron run. This patch updates used_memory_peak to the current memory usage if the current memory usage is higher than the recorded used_memory_peak value. (And it only calls zmalloc_used_memory() once instead of twice as it was doing before.)

With the new behavior it is possible to specify just the start in the range (the end will be assumed to be the first byte), or it is possible to specify both start and end. This is useful to change the behavior of the command when looking for zeros inside a string. 1) If the user specifies both start and end, and no 0 is found inside the range, the command returns -1. 2) If instead no range is specified, or just the start is given, even if in the actual string no 0 bit is found, the command returns the first bit on the right after the end of the string. So for example if the string stored at key foo is "\xff\xff": BITPOS foo (returns 16) BITPOS foo 0 -1 (returns -1) BITPOS foo 0 (returns 16) The idea is that when no end is given the user is just looking for the first bit that is zero and can be set to 1 with SETBIT, as it is "available". Instead when a specific range is given, we just look for a zero within the boundaries of the range.

It appears to work but more stress testing, and both unit tests and fuzzy testing, is needed in order to ensure the implementation is sane.

It was verified in practice that this test is able to stress much more the implementation by introducing errors that were only trivially to detect with different offsets but impossible to detect starting always at zero and counting bits the full length of the string.

This commit changes the findBigKeys() function in redis-cli.c to use the new SCAN command for iterating the keyspace, rather than RANDOMKEY. Because we can know when we're done using SCAN, it will exit after exhausting the keyspace.

The computation is just something to take the CPU busy, no need to use a specific type. Since stdint.h was not included this prevented compilation on certain systems.

An unit can abort in the middle for an error. The next unit should not assume that the instances are in a clean state, and must restart what was left killed.

Sentinel tests are designed to be dependent on the previous tests in the same unit, so usually we can't continue with the next test in the same unit if a previous test failed.

The test was previously performed by removing the master from the Sentinel monitored masters. The test with the Sentinels crashed is more similar to real-world partitions / failures.

Also kill_instance was modified to warn when a test will try to kill the same instance multiple times for error.

The area a number of mandatory tests to craete a stable setup for testing that is not too sensitive to timing issues. All those tests moved to includes/init-tests, and marked as (init).

Now that we have a runtime configuration system, it is very important to be able to log how the Sentinel configuration changes over time because of API calls.
