Reserve 2 bits out of hash-field expiration time (`EB_EXPIRE_TIME_MAX`) for possible future lightweight indexing/categorizing of fields. It can be achieved by hacking HFE as follows: ``` HPEXPIREAT key [ 2^47 + USER_INDEX ] FIELDS numfields field [field …] ``` Redis will also need to expose kind of `HEXPIRESCAN` and `HEXPIRECOUNT` for this idea. Yet to be better defined. `HFE_MAX_ABS_TIME_MSEC` constraint must be enforced only at API level. Internally, the expiration time can be up to `EB_EXPIRE_TIME_MAX` for future readiness.

* For replica sake, rewrite commands `H*EXPIRE*` , `HSETF`, `HGETF` to have absolute unix time in msec. * On active-expiration of field, propagate HDEL to replica (`propagateHashFieldDeletion()`) * On lazy-expiration, propagate HDEL to replica (`hashTypeGetValue()` now calls `hashTypeDelete()`. It also takes care to call `propagateHashFieldDeletion()`). * Fix `H*EXPIRE*` command such that if it gets flag `LT` and it doesn’t have any expiration on the field then it will considered as valid condition. Note, replicas doesn’t make any active expiration, and should avoid lazy expiration. On `hashTypeGetValue()` it doesn't check expiration (As long as the master didn’t request to delete the field, it is valid) TODO: * Attach `dbid` to HASH metadata.

Add RDB de/serialization for HFE This PR adds two new RDB types: `RDB_TYPE_HASH_METADATA` and `RDB_TYPE_HASH_LISTPACK_TTL` to save HFE data. When the hash RAM encoding is dict, it will be saved in the former, and when it is listpack it will be saved in the latter. Both formats just add the TTL value for each field after the data that was previously saved, i.e HASH_METADATA will save the number of entries and, for each entry, key, value and TTL, whereas listpack is saved as a blob. On read, the usual dict <--> listpack conversion takes place if required. In addition, when reading a hash that was saved as a dict fields are actively expired if expiry is due. Currently this slao holds for listpack encoding, but it is supposed to be removed. TODO: Remove active expiry on load when loading from listpack format (unless we'll decide to keep it)

In order to speed up tests, avoid saving an RDB (mostly notable on shutdown), except for tests that explicitly test the RDB mechanism In addition, use `shutdown-on-sigterm force` to prevetn shutdown from failing in case the server is in the middle of the initial AOFRW Also a a test that checks that the `shutdown-on-sigterm default` is to refuse shutdown if there's an initial AOFRW Co-authored-by:

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 Co-authored-by:

If we have integer scores on the sorted set we're not using the fastest way to reply by calling `d2string` which uses `double2ll` and `ll2string` when it can, instead of `fpconv_dtoa`. This results by some 50% performance improvement in certain cases of integer scores for both RESP2 and RESP3, and no apparent impact on double scores. Co-authored-by:

Improve memory efficiency of list keys ## Description of the feature The new listpack encoding uses the old `list-max-listpack-size` config to perform the conversion, which we can think it of as a node inside a quicklist, but without 80 bytes overhead (internal fragmentation included) of quicklist and quicklistNode structs. For example, a list key with 5 items of 10 chars each, now takes 128 bytes instead of 208 it used to take. ## Conversion rules * Convert listpack to quicklist When the listpack length or size reaches the `list-max-listpack-size` limit, it will be converted to a quicklist. * Convert quicklist to listpack When a quicklist has only one node, and its length or size is reduced to half of the `list-max-listpack-size` limit, it will be converted to a listpack. This is done to avoid frequent conversions when we add or remove at the bounding size or length. ## Interface changes 1. add list entry param to listTypeSetIteratorDirection When list encoding is listpack, `listTypeIterator->lpi` points to the next entry of current entry, so when changing the direction, we need to use the current node (listTypeEntry->p) to update `listTypeIterator->lpi` to the next node in the reverse direction. ## Benchmark ### Listpack VS Quicklist with one node * LPUSH - roughly 0.3% improvement * LRANGE - roughly 13% improvement ### Both are quicklist * LRANGE - roughly 3% improvement * LRANGE without pipeline - roughly 3% improvement From the benchmark, as we can see from the results 1. When list is quicklist encoding, LRANGE improves performance by <5%. 2. When list is listpack encoding, LRANGE improves performance by ~13%, the main enhancement is brought by `addListListpackRangeReply()`. ## Memory usage 1M lists(key:0~key:1000000) with 5 items of 10 chars ("hellohello") each. shows memory usage down by 35.49%, from 214MB to 138MB. ## Note 1. Add conversion callback to support doing some work before conversion Since the quicklist iterator decompresses the current node when it is released, we can no longer decompress the quicklist after we convert the list.

optimizing d2string() and addReplyDouble() with grisu2: double to string conversion based on Florian Loitsch's Grisu-algorithm (#10587) All commands / use cases that heavily rely on double to a string representation conversion, (e.g. meaning take a double-precision floating-point number like 1.5 and return a string like "1.5" ), could benefit from a performance boost by swapping snprintf(buf,len,"%.17g",value) by the equivalent [fpconv_dtoa](https://github.com/night-shift/fpconv) or any other algorithm that ensures 100% coverage of conversion. This is a well-studied topic and Projects like MongoDB. RedPanda, PyTorch leverage libraries ( fmtlib ) that use the optimized double to string conversion underneath. The positive impact can be substantial. This PR uses the grisu2 approach ( grisu explained on https://www.cs.tufts.edu/~nr/cs257/archive/florian-loitsch/printf.pdf section 5 ). test suite changes: Despite being compatible, in some cases it produces a different result from printf, and some tests had to be adjusted. one case is that `%.17g` (which means %e or %f which ever is shorter), chose to use `5000000000` instead of 5e+9, which sounds like a bug? In other cases, we changed TCL to compare numbers instead of strings to ignore minor rounding issues (`expr 0.8 == 0.79999999999999999`)

Fix broken protocol in MISCONF error, RM_Yield bugs, RM_Call(EVAL) OOM check bug, and new RM_Call checks. (#10786) * Fix broken protocol when redis can't persist to RDB (general commands, not modules), excessive newline. regression of #10372 (7.0 RC3) * Fix broken protocol when Redis can't persist to AOF (modules and scripts), missing newline. * Fix bug in OOM check of EVAL scripts called from RM_Call. set the cached OOM state for scripts before executing module commands too, so that it can serve scripts that are executed by modules. i.e. in the past EVAL executed by RM_Call could have either falsely fail or falsely succeeded because of a wrong cached OOM state flag. * Fix bugs with RM_Yield: 1. SHUTDOWN should only accept the NOSAVE mode 2. Avoid eviction during yield command processing. 3. Avoid processing master client commands while yielding from another client * Add new two more checks to RM_Call script mode. 1. READONLY You can't write against a read only replica 2. MASTERDOWN Link with MASTER is down and `replica-serve-stale-data` is set to `no` * Add new RM_Call flag to let redis automatically refuse `deny-oom` commands while over the memory limit. * Add tests to cover various errors from Scripts, Modules, Modules calling scripts, and Modules calling commands in script mode. Add tests: * Looks like the MISCONF error was completely uncovered by the tests, add tests for it, including from scripts, and modules * Add tests for NOREPLICAS from scripts * Add tests for the various errors in module RM_Call, including RM_Call that calls EVAL, and RM_call in "eval mode". that includes: NOREPLICAS, READONLY, MASTERDOWN, MISCONF

FLUSHDB and FLUSHALL add call forceCommandPropagation / FLUSHALL reset dirty counter to 0 if we enable save (#10691) ## FLUSHALL We used to restore the dirty counter after `rdbSave` zeroed it if we enable save. Otherwise FLUSHALL will not be replicated nor put into the AOF. And then we do increment it again below. Without that extra dirty++, when db was already empty, FLUSHALL will not be replicated nor put into the AOF. We now gonna replace all that dirty counter magic with a call to forceCommandPropagation (REPL and AOF), instead of all the messing around with the dirty counter. Added tests to cover three part (dirty counter, REPL, AOF). One benefit other than cleaner code is that the `rdb_changes_since_last_save` is correct in this case. ## FLUSHDB FLUSHDB was not replicated nor put into the AOF when db was already empty. Unlike DEL on a non-existing key, FLUSHDB always does something, and that's to call the module hook. So basically FLUSHDB is never a NOP, and thus it should always be propagated. Not doing that, could mean that if a module does something in that hook, and wants to avoid issues of that hook being missing on the replica if the db is empty, it'll need to do complicated things. So now FLUSHDB add call forceCommandPropagation, we will always propagate FLUSHDB. Always propagating FLUSHDB seems like a safe approach that shouldn't have any drawbacks (other than looking odd) This was mentioned in #8972 ## Test section: We actually found it while solving a race condition in the BGSAVE test (other.tcl). It was found in extra_ci Daily Arm64 (test-libc-malloc). ``` [exception]: Executing test client: ERR Background save already in progress. ERR Background save already in progress ``` It look like `r flushdb` trigger (schedule) a bgsave right after `waitForBgsave r` and before `r save`. Changing flushdb to flushall, FLUSHALL will do a foreground save and then set the dirty counter to 0.

This PR attempts to solve two problems that happen sometime in valgrind: `ERR Background save already in progress` and `not bgsave not aborted` the test used to populate the database with DEBUG, which didn't increment the dirty counter, so couldn't trigger an automatic bgsave. then it used a manual bgsave, and aborted it (when it got aborted it populated the dirty counter), and then it tried to do another bgsave. that other bgsave could have failed if the automatic one already started.

# Background The main goal of this PR is to remove relevant logics on Lua script verbatim replication, only keeping effects replication logic, which has been set as default since Redis 5.0. As a result, Lua in Redis 7.0 would be acting the same as Redis 6.0 with default configuration from users' point of view. There are lots of reasons to remove verbatim replication. Antirez has listed some of the benefits in Issue #5292: >1. No longer need to explain to users side effects into scripts. They can do whatever they want. >2. No need for a cache about scripts that we sent or not to the slaves. >3. No need to sort the output of certain commands inside scripts (SMEMBERS and others): this both simplifies and gains speed. >4. No need to store scripts inside the RDB file in order to startup correctly. >5. No problems about evicting keys during the script execution. When looking back at Redis 5.0, antirez and core team decided to set the config `lua-replicate-commands yes` by default instead of removing verbatim replication directly, in case some bad situations happened. 3 years later now before Redis 7.0, it's time to remove it formally. # Changes - configuration for lua-replicate-commands removed - created config file stub for backward compatibility - Replication script cache removed - this is useless under script effects replication - relevant statistics also removed - script persistence in RDB files is also removed - Propagation of SCRIPT LOAD and SCRIPT FLUSH to replica / AOF removed - Deterministic execution logic in scripts removed (i.e. don't run write commands after random ones, and sorting output of commands with random order) - the flags indicating which commands have non-deterministic results are kept as hints to clients. - `redis.replicate_commands()` & `redis.set_repl()` changed - now `redis.replicate_commands()` does nothing and return an 1 - ...and then `redis.set_repl()` can be issued before `redis.replicate_commands()` now - Relevant TCL cases adjusted - DEBUG lua-always-replicate-commands removed # Other changes - Fix a recent bug comparing CLIENT_ID_AOF to original_client->flags instead of id.

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) Co-authored-by:

Since we measure the COW size in this test by changing some keys and reading the reported COW size, we need to ensure that the "dismiss mechanism" (#8974) will not free memory and reduce the COW size. For that, this commit changes the size of the keys to 512B (less than a page). and because some keys may fall into the same page, we are modifying ten keys on each iteration and check for at least 50% change in the COW size.

The main idea is how to allow a master to load replication info from RDB file when rebooting, if master can load replication info it means that replicas may have the chance to psync with master, it can save much traffic. The key point is we need guarantee safety and consistency, so there are two differences between master and replica: 1. master would load the replication info as secondary ID and offset, in case other masters have the same replid. 2. when master loading RDB, it would propagate expired keys as DEL command to replication backlog, then replica can receive these commands to delete stale keys. p.s. the expired keys when RDB loading is useful for users, so we show it as `rdb_last_load_keys_expired` and `rdb_last_load_keys_loaded` in info persistence. Moreover, after load replication info, master should update `no_replica_time` in case loading RDB cost too long time.

This PR adds a spell checker CI action that will fail future PRs if they introduce typos and spelling mistakes. This spell checker is based on blacklist of common spelling mistakes, so it will not catch everything, but at least it is also unlikely to cause false positives. Besides that, the PR also fixes many spelling mistakes and types, not all are a result of the spell checker we use. Here's a summary of other changes: 1. Scanned the entire source code and fixes all sorts of typos and spelling mistakes (including missing or extra spaces). 2. Outdated function / variable / argument names in comments 3. Fix outdated keyspace masks error log when we check `config.notify-keyspace-events` in loadServerConfigFromString. 4. Trim the white space at the end of line in `module.c`. Check: https://github.com/redis/redis/pull/7751 5. Some outdated https link URLs. 6. Fix some outdated comment. Such as: - In README: about the rdb, we used to said create a `thread`, change to `process` - dbRandomKey function coment (about the dictGetRandomKey, change to dictGetFairRandomKey) - notifyKeyspaceEvent fucntion comment (add type arg) - Some others minor fix in comment (Most of them are incorrectly quoted by variable names) 7. Modified the error log so that users can easily distinguish between TCP and TLS in `changeBindAddr`

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.

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

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

- improve stream rdb encoding test to include more types of stream metadata - add test to cover various ziplist encoding entries (although it does look like the stress test above it is able to find some too - add another test for ziplist encoding for hash with full sanitization - add similar ziplist encoding tests for list

on ci.redis.io the test fails a lot, reporting that bgsave didn't end. increaseing the timeout we wait for that bgsave to get aborted. in addition to that, i also verify that it indeed got aborted by checking that the save counter wasn't reset. add another test to verify that a successful bgsave indeed resets the change counter.

* tests/valgrind: don't use debug restart DEBUG REATART causes two issues: 1. it uses execve which replaces the original process and valgrind doesn't have a chance to check for errors, so leaks go unreported. 2. valgrind report invalid calls to close() which we're unable to resolve. So now the tests use restart_server mechanism in the tests, that terminates the old server and starts a new one, new PID, but same stdout, stderr. since the stderr can contain two or more valgrind report, it is not enough to just check for the absence of leaks, we also need to check for some known errors, we do both, and fail if we either find an error, or can't find a report saying there are no leaks. other changes: - when killing a server that was already terminated we check for leaks too. - adding DEBUG LEAK which was used to test it. - adding --trace-children to valgrind, although no longer needed. - since the stdout contains two or more runs, we need slightly different way of checking if the new process is up (explicitly looking for the new PID) - move the code that handles --wait-server to happen earlier (before watching the startup message in the log), and serve the restarted server too. * squashme - CR fixes

This bug was introduced by a recent change in which readQueryFromClient is using freeClientAsync, and despite the fact that now freeClientsInAsyncFreeQueue is in beforeSleep, that's not enough since it's not called during loading in processEventsWhileBlocked. furthermore, afterSleep was called in that case but beforeSleep wasn't. This bug also caused slowness sine the level-triggered mode of epoll kept signaling these connections as readable causing us to keep doing connRead again and again for ll of these, which keep accumulating. now both before and after sleep are called, but not all of their actions are performed during loading, some are only reserved for the main loop. fixes issue #7215

Testing with Solaris C compiler (SunOS 5.11 11.2 sun4v sparc sun4v) there were issues compiling due to atomicvar.h and running the tests also failed because of "tail" usage not conform with Solaris tail implementation. This commit fixes both the issues.
