marko	06375f3cb1	branches/zip: Make innodb_adaptive_hash_index settable. btr_search_disabled: Rename to btr_search_enabled and change the type to char, so that it can be directly linked to the MySQL parameters. Note that the variable is protected by btr_search_latch and btr_search_enabled_mutex, a new mutex introduced in this patch. btr_search_enabled_mutex: A new mutex, to protect btr_search_enabled together with btr_search_latch. buf_pool_drop_hash_index(): New function, to be called from btr_search_disable(). btr_search_disable(), btr_search_enable(): Fix bugs. These functions were previously unused. btr_search_guess_on_hash(), btr_search_build_page_hash_index(): Check btr_search_enabled once more, while holding btr_search_latch. btr_cur_search_to_nth_level(): Note that the reads of btr_search_enabled may be dirty and explain why it should not be a problem. innobase_adaptive_hash_index: Remove. The variable btr_search_enabled will be used directly instead. innodb_adaptive_hash_index_update(): New function, an update callback for innodb_adaptive_hash_index. This will call either btr_search_disable() or btr_search_enable() when the value is assigned. The functions will be called even if the value does not appear to be changed, e.g., when setting from TRUE to TRUE or FALSE to FALSE. rb://85 approved by Heikki Tuuri.

calvin	61a3389553	branches/zip: Implement the system tablespace tagging described on the wiki: https://svn.innodb.com/innobase/InnoDB_version_and_feature_compatibility A brief description of the changes: * The file format tag will be saved in the trx system page, starting at (UNIV_PAGE_SIZE - 16) for 8 bytes. * The configuration parameter innodb_file_format_check is introduced. This variable can be set to on/off and any of the supported file formats in the configuration file, but can only be set to any of the supported file formats during runtime. The default is on. * During table create/open, check the current file format against the max in file_format_max. If the current file format is newer, update file_format_max and tag the system tablespace with the newer one in a normal mtr. * During startup, write the tag to the error log and check it against DICT_TF_FORMAT_MAX. Refuse to start with error, if -- DICT_TF_FORMAT_MAX < the tag, and -- innodb_file_format_check is ON Print out a warning , if -- DICT_TF_FORMAT_MAX < the tag, but -- innodb_file_format_check is off * The system tablespace tag is re-settable using: set innodb_file_format_check = <file_format> Approved by: Sunny	18 years ago
sunny	fbe40461c3	branches/zip: Fix a bug in the sync debug code where a lock with level SYNC_LEVEL_VARYING would cause an assertion failure when a thread tried to release it. We still have to check because it's a varying lock and could have been added later, so if the lookup fails then we simply ignore it and return TRUE.	18 years ago

marko	1d1dc31a06	branches/zip: Introduce UNIV_INTERN, a linkage specifier for InnoDB-global symbols. Use it for all definitions of non-static variables and functions. lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static. It is referenced from pars0grm.c. Actually, according to nm .libs/ha_innodb.so\|grep -w '[ABCE-TVXYZ]' the following symbols are still global: * The vtable for class ha_innodb * pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs The required changes to the Bison-generated file pars0grm.c will be addressed in a separate commit, which will add a script similar to make_flex.sh. The class ha_innodb is renamed from class ha_innobase by a #define. Thus, there will be no clash with the builtin InnoDB. However, there will be some overhead for invoking virtual methods of class ha_innodb. Ideas for making the vtable hidden are welcome. -fvisibility=hidden is not available in GCC 3.	18 years ago
