the code in:
c->flags &= ~(CLIENT_TRACKING|CLIENT_TRACKING_BROKEN_REDIR);
will do sign extension and turn on all the high 31 bits
no damage so far since we don't have any yet
+ memcpy(&id,ri.key,sizeof(id));
The memcpy from the key to the id reliease on the fact that this key
*should* be 8 bytes long as it was entered as such a few lines up the
code.
BUT if someone will change the code to the point this is no longer true,
current code can trash the stack which makes debugging very hard
while this fix will result in some garbage id, or even page fault.
Both are preferable to stack mangaling.
it seems that commit b087dd1db60ed23d9e59304deb0b1599437f6e23 accidentially changed
gen_write_load to not use deferred client, which causes them to be slower and not
generate high load which they should, making some tests less effecitive
Changes in behavior:
- Change server.stream_node_max_entries from int64_t to long long, so that it can be used by the generic infra
- standard error reply instead of "repl-backlog-size must be 1 or greater" and such
- tls-port and a few TLS booleans were readable (config get) even when USE_OPENSSL was off (now they aren't)
- syslog-enabled, syslog-ident, cluster-enabled, appendfilename, and supervised didn't have a get (now they do)
- pidfile was initialized to NULL in InitServerConfig but had CONFIG_DEFAULT_PID_FILE in rewriteConfig (so the real default was "", but rewrite would cause it to be set), fixed the rewrite.
- TLS config in server.h was uninitialized (if no tls config args were provided)
Adding test for sanity and coverage
- Adding is_valid_fn and update_fn, both return 1 for success and 0 for failure with an optional error message.
- Bugfix in handling boundary check of unsigned numeric types (was boundaries as signed)
- Adding more numeric types to generic mechanism: uint, ulonglong, long, time_t, off_t
- More verbose error replies ("argument must be between" in out of range CONFIG SET (like config file parsing)
- add capability for each config to have a callback to check if value is valid and return error string
will enable converting many of the remaining custom configs into generic ones (reducing the x4 repetition for set,get,config,rewrite)
- add capability for each config to to run some update code after config is changed (only for CONFIG SET)
will also enable converting many of the remaining custom configs into generic ones
- add capability to move default values from server.h and server.c to config.c
will reduce many excess lines in server.h and server.c (plus, no need to rebuild the entire code base when a default change 8-))
other behavior changes:
- fix bug in bool config get (always returning 'yes')
- fix a bug in modifying jemalloc-bg-thread at runtime (didn't call set_jemalloc_bg_thread, due to bad merge conflict resolution (my fault))
- side effect when a failed attempt to enable activedefrag at runtime, we now respond with -ERR and not with -DISABLED
