René Cannaò	b57ff42b9c	Drafting again support for ClickHouse Introduced new ClickHouse Server module Introduced new ClickHouse Authentication module None of the two new modules are working yet: only initialized.	9 years ago
René Cannaò	21df8d1346	Return 0 checksum if mysql_users is empty If table `mysql_users` is empty, its checksum must be all zeros	9 years ago
René Cannaò	e3c4cb9964	A lot of changes all related to Cluster In `MySQL_Cluster` class added functions to sync with remote node, like: - `pull_mysql_query_rules_from_peer()` - `pull_mysql_servers_from_peer()` - `pull_mysql_users_from_peer()` - `pull_proxysql_servers_from_peer()` Added 8 new global variables in Admin. 4 variables determine after how many different checks the remote configuration will be synced: - cluster_mysql_query_rules_diffs_before_sync - cluster_mysql_servers_diffs_before_sync - cluster_mysql_users_diffs_before_sync - cluster_proxysql_servers_diffs_before_sync 4 variables determine if after a remote sync the changes need to be written to disk: - cluster_mysql_query_rules_save_to_disk - cluster_mysql_servers_save_to_disk - cluster_mysql_users_save_to_disk - cluster_proxysql_servers_save_to_disk Table `proxysql_servers` is now automatically loaded from disk to memory and into runtime at startup. Added new Admin's command `LOAD PROXYSQL SERVERS FROM CONFIG` to load `proxysql_servers` from config file to memory (not runtime). Internal structures with credentials in MySQL_Authentication moved from `unsorted_map` to `map` : this to ensure the right order when generating the checksum. Config file supports both `address` and `hostname` for `mysql_servers` and `proxysql_servers` , #1091 `ProxySQL_Admin::load_proxysql_servers_to_runtime()` now has a lock or no lock option, to avoid deadlock For now, Cluster module is quite verbose.	9 years ago
René Cannaò	708f14a6e6	More accurate memory metrics	9 years ago
René Cannaò	1414d4430f	Introduced new table stats_memory_metrics Here an example: ``` Admin> SELECT * FROM stats_memory_metrics ORDER BY variable_name; +----------------------+----------------+ \| Variable_Name \| Variable_Value \| +----------------------+----------------+ \| Auth_memory \| 836 \| \| SQLite3_memory_bytes \| 1636648 \| \| jemalloc_active \| 3469312 \| \| jemalloc_allocated \| 3055248 \| \| jemalloc_mapped \| 14680064 \| \| jemalloc_metadata \| 1480576 \| \| jemalloc_resident \| 4542464 \| \| jemalloc_retained \| 0 \| \| query_digest_memory \| 459 \| +----------------------+----------------+ 9 rows in set (0.00 sec) ```	9 years ago
René Cannaò	64eb4cda35	Remove spinlock from MySQL Auth #977	9 years ago
René Cannaò	6469ff269b	num_connections_used incorrectly reset	9 years ago
René Cannaò	f0f85a44fe	Introduced table stats.stats_mysql_users Example: ``` mysql> select * from stats_mysql_users; +----------+----------------------+--------------------------+ \| username \| frontend_connections \| frontend_max_connections \| +----------+----------------------+--------------------------+ \| root \| 0 \| 10000 \| \| user1 \| 0 \| 10000 \| \| user2 \| 1 \| 10000 \| +----------+----------------------+--------------------------+ 3 rows in set (0.00 sec) ```	9 years ago
René Cannaò	b449a3ffb4	Merge branch 'master' into v1.4.0	9 years ago
Christopher Troup	0f75916a2e	Ensure that users num_connections_used doesn't get incremented if connection rejected If the users connection is rejected we shouldn't be incrementing `num_connections_used` on the account_details object. This leads to `free_users` dropping below zero and _all_ subsequent requests getting rejected for that user. Refs #940	9 years ago
René Cannaò	a6c53d0d12	Revert "Refactor header includes."	9 years ago
Maxim Bublis	30dbcc21a8	Refactor header includes. * reduce build time by 25%; * remove circular dependency on `cpp.h` and other headers. * fixes issue with `my_global.h` from mariadbclient which redefines `__attribute__`, that leads to broken STL and GCC intrinsics if `<algorithm>` wasn't included prior including this header; * fixes another issue with redefined `__attribute__` which leads to `_conn_exchange_t` not being aligned to cache line size; * removes `pthread_setstacksize` calls as `my_global.h` redefines `pthread_setstacksize` to be `pthread_dummy(0)` which led to stack size being never adjusted; * add missing include guards to some headers; * remove unused proxysql_hash.h header.	9 years ago
Maxim Bublis	043a321e55	Cleanup legacy codebase.	9 years ago
René Cannaò	95a6ed5f26	Speed up the cleanup of MySQL_Authentication #802 This drastically reduces the time to gracefully shutdown proxysql in case of hundreds of thousands of mysql users	9 years ago
René Cannaò	1ca56c9b3e	Speeds up LOAD MYSQL USERS TO RUNTIME #802 MySQL_Authentication::add() used to delete a user, and then create it. This patch applied the change in place if possible. With 100k users, not it is around 7 times faster.	9 years ago
René Cannaò	d0d764533d	Specify when a mysql_users.max_connections is reached #794 It also fixes: * bug in deps/Makefile related to cleanall * crashing bug in HGCU_thread_run()	9 years ago
René Cannaò	c710f54987	Compiling optimization * converted MySQL_Authentication to use unsorted_map instead of btree_map * Query_Cache now uses pointers to KV_BtreeArray * removed some unnecesary headers	10 years ago
René Cannaò	b24d9e8d2b	Bugfixes on encrypted password	10 years ago
René Cannaò	60b3dcaadf	More on sha1_passs on MySQL_Authentication() MySQL_Authentication() is now able to keep track of sha1_pass between LOAD MYSQL USERS TO RUNTIME wothout the need of a new user uathentication	10 years ago
René Cannaò	625c969a5d	Use hash password in mysql_users This feature is not completed yet. libmariadb/password.c is patched to use either password or sha1(password) Class MySQL_Connection_userinfo() is expanded to also support sha1_pass Inroduced MySQL_Authentication::set_SHA1() to store this information at runtime only Added several auxiliary functions	10 years ago
René Cannaò	3f472d41aa	Fix on num_connections_used not initialized	11 years ago
René Cannaò	76edfb126f	Further implementation of libmariadb client	11 years ago
René Cannaò	d9a2df7039	Query Cache is not a plugin anymore	11 years ago
René Cannaò	59507675e5	MySQL_Thread, MySQL_Threads_Handler and MySQL_Authentication are no longer modules	11 years ago
