**Changes:**
- Adds listpack support to hash field expiration
- Implements hgetf/hsetf commands
**Listpack support for hash field expiration**
We keep field name and value pairs in listpack for the hash type. With
this PR, if one of hash field expiration command is called on the key
for the first time, it converts listpack layout to triplets to hold
field name, value and ttl per field. If a field does not have a TTL, we
store zero as the ttl value. Zero is encoded as two bytes in the
listpack. So, once we convert listpack to hold triplets, for the fields
that don't have a TTL, it will be consuming those extra 2 bytes per
item. Fields are ordered by ttl in the listpack to find the field with
minimum expiry time efficiently.
**New command implementations as part of this PR:**
- HGETF command
For each specified field get its value and optionally set the field's
expiration time in sec/msec /unix-sec/unix-msec:
```
HGETF key
[NX | XX | GT | LT]
[EX seconds | PX milliseconds | EXAT unix-time-seconds | PXAT
unix-time-milliseconds | PERSIST]
<FIELDS count field [field ...]>
```
- HSETF command
For each specified field value pair: set field to value and optionally
set the field's expiration time in sec/msec /unix-sec/unix-msec:
```
HSETF key
[DC]
[DCF | DOF]
[NX | XX | GT | LT]
[GETNEW | GETOLD]
[EX seconds | PX milliseconds | EXAT unix-time-seconds | PXAT
unix-time-milliseconds | KEEPTTL]
<FVS count field value [field value …]>
```
Todo:
- Performance improvement.
- rdb load/save
- aof
- defrag

Redis Test Suite
The normal execution mode of the test suite involves starting and manipulating
local redis-server instances, inspecting process state, log files, etc.
The test suite also supports execution against an external server, which is
enabled using the --host and --port parameters. When executing against an
external server, tests tagged external:skip are skipped.
There are additional runtime options that can further adjust the test suite to match different external server configurations:
| Option | Impact |
|---|---|
--singledb |
Only use database 0, don't assume others are supported. |
--ignore-encoding |
Skip all checks for specific encoding. |
--ignore-digest |
Skip key value digest validations. |
--cluster-mode |
Run in strict Redis Cluster compatibility mode. |
--large-memory |
Enables tests that consume more than 100mb |
Tags
Tags are applied to tests to classify them according to the subsystem they test, but also to indicate compatibility with different run modes and required capabilities.
Tags can be applied in different context levels:
start_servercontexttagscontext that bundles several tests together- A single test context.
The following compatibility and capability tags are currently used:
| Tag | Indicates |
|---|---|
external:skip |
Not compatible with external servers. |
cluster:skip |
Not compatible with --cluster-mode. |
large-memory |
Test that requires more than 100mb |
tls:skip |
Not compatible with --tls. |
needs:repl |
Uses replication and needs to be able to SYNC from server. |
needs:debug |
Uses the DEBUG command or other debugging focused commands (like OBJECT REFCOUNT). |
needs:pfdebug |
Uses the PFDEBUG command. |
needs:config-maxmemory |
Uses CONFIG SET to manipulate memory limit, eviction policies, etc. |
needs:config-resetstat |
Uses CONFIG RESETSTAT to reset statistics. |
needs:reset |
Uses RESET to reset client connections. |
needs:save |
Uses SAVE or BGSAVE to create an RDB file. |
When using an external server (--host and --port), filtering using the
external:skip tags is done automatically.
When using --cluster-mode, filtering using the cluster:skip tag is done
automatically.
When not using --large-memory, filtering using the largemem:skip tag is done
automatically.
In addition, it is possible to specify additional configuration. For example, to
run tests on a server that does not permit SYNC use:
./runtest --host <host> --port <port> --tags -needs:repl
