marko	d03bdd38bc	branches/zip: btr_free_externally_stored_field(): Clear rec_zip_size when rec == NULL.	18 years ago
marko	4b23d55164	branches/zip: page_zip_compress(): Do not call deflate(&c_stream, Z_FULL_FLUSH) unless more than 6 bytes are available for the output. This should remove the possibility that deflate() returns Z_OK without consuming all input.	18 years ago
marko	a8635f7e29	branches/zip: buf_page_get_gen(): Ignore "guess" if it does not point to buf_pool->chunks[]->blocks[]. buf_block_is_uncompressed(): New function, to detect if a block points to buf_pool->chunks[]->blocks[].	18 years ago
marko	a3c79ebcfc	branches/zip: buf_page_hash_get(): Fix a debug assertion that was accidentally negated in r2043.	18 years ago
marko	89f0e34f2a	branches/zip: trx_rollback_or_clean_all_recovered(): Acquire the kernel_mutex in the beginning of each loop, as was the case until r2040. The bug was spotted by Heikki.	18 years ago
marko	7187686bda	branches/zip: sync0sync.h: Define mutex_free as mutex0_free, because symbols defined in innodb_redefine.h must not be undefined. After this change, innodb_redefine.h will define mutex0_free instead of mutex_free, and everything is fine.	18 years ago
marko	cf98f66049	branches/zip: Allow the symbols in the dynamic InnoDB plugin to be redefined so that the dynamic plugin can replace the builtin InnoDB in MySQL 5.1. ha_innodb.cc, handler0alter.cc: #include "univ.i" before any other InnoDB header files or before defining any symbols innodb_redefine.h: New file, to contain a mapping of symbols. The idea is that this file will be replaced in the build process; because this is a large file that can be generated automatically, it does not make sense to keep it under version control. univ.i: #include "innodb_redefine.h" and #define ha_innobase ha_innodb Makefile.am (ha_innodb_la_CXXFLAGS): Remove -Dha_innobase=ha_innodb NOTE: there are still some issues in the source code. One known issue is the #undef mutex_free in sync0sync.h, which will cause the plugin to call the function mutex_free in the builtin InnoDB. The preprocessor symbols defined in innodb_redefine.h must not be undefined or redefined anywhere in the code.	18 years ago
marko	418d050f91	branches/zip: Remove the parameter innodb_dynamic, and always call the plugin "InnoDB", not "InnoDBzip". We can disable the builtin InnoDB by mysqld --skip-innodb. If the builtin InnoDB is not disabled, installing the InnoDB plugin by the same name will not work. innodb_plugin_init(): Ignore differences in the PLUGIN_VAR_READONLY flag.	18 years ago
marko	1bfa27fb91	branches/zip: Remove warnings for BUILD/compile-... --warning-mode=pedantic. ha_innobase::write_row(): The printf format %p expects const void*. STRUCT_FLD: Do not use the GCC extension when __STRICT_ANSI__ is defined. row_merge_read_clustered_index(): Compound initializers must not contain variables. Assign to struct fields instead.	18 years ago
marko	66e193b4ba	branches/zip: buf_page_init_low(): Initialize also flush_type.	18 years ago
marko	63968a86e6	branches/zip: page_zip_compress(): Flag the compressed stream completely initialized, although Valgrind believes that some bits in the 7th or 8th bytes from the end are uninitialized. (They might be, but the decompressor should not care about those bits after encountering the end-of-stream marker in the compressed bit stream.)	18 years ago
marko	d1ef07b308	branches/zip: Check that page_zip->data is defined, not page_zip itself.	18 years ago
marko	589393da83	branches/zip: Improve Valgrind instrumentation. btr_cur_optimistic_insert(): On compressed tablespaces, check that both the compressed and the uncompressed page are completely initialized in the beginning of the function. page_zip_compress(): After successful compression, check that the compressed page is completely initialized.	18 years ago
marko	15d01d3e31	branches/zip: Add some more Valgrind instrumentation. page_zip_write_rec(), page_zip_write_blob_ptr(), page_zip_write_node_ptr(), page_zip_write_trx_id_and_roll_ptr(), page_zip_clear_rec(), page_zip_rec_set_deleted(), page_zip_rec_set_owned(), page_zip_dir_insert(), page_zip_dir_delete(), page_zip_dir_add_slot(), page_zip_reorganize(), page_zip_copy(), page_zip_get_trailer_len(), page_zip_write_header(): Assert that the complete contents of the compressed page is defined.	18 years ago
marko	f8e3c447a3	branches/zip: Improve Valgrind instrumentation. page_zip_compress(): Assert that the contents of the uncompressed page is entirely initialized. page_zip_decompress(): Assert that the contents of the compressed page is entirely initialized. Assert that the uncompressed page is entirely writeable. Flag the uncompressed page uninitialized in the beginning.	18 years ago
marko	dd2dd78cd7	branches/zip: buf_block_align(): Add missing type conversion.	18 years ago
marko	6eb43b3d44	branches/zip: Correct the Valgrind instrumentation of r2041. Use UNIV_MEM_ASSERT_RW() instead of UNIV_MEM_VALID(). The latter flags memory defined; the former checks that it is defined.	18 years ago
marko	fe6e780d82	branches/zip: buf_LRU_block_remove_hashed_page(): Add some Valgrind instrumentation.	18 years ago
marko	a815c47ccb	branches/zip: buf_buddy_relocate(): The src block may be partially freed. Remove the Valgrind check about it.	18 years ago
marko	92df6720be	branches/zip: Improve Valgrind instrumentation. buf_buddy_relocate(): Allow the source block to contain uninitialized data. buf0buddy.c: Replace the remaining VALGRIND_CHECK_ macros with the wrappers defined in univ.i.	18 years ago
marko	902893c719	branches/zip: Improve Valgrind instrumentation. buf_LRU_free_block(): Check that the block descriptor contains valid data. buf_buddy_relocate(): Check that the source block contains valid data. buf_page_get_gen(): Do not dereference bpage after calling buf_relocate(). This avoids a bogus Valgrind warning; the memory itself was valid. buf_page_hash_get(): Check that the returned block descriptor contains valid data.	18 years ago
marko	281d3966cf	branches/zip: trx_rollback_or_clean_all_without_sess(): Rename to trx_rollback_or_clean_all_recovered().	18 years ago
marko	b013f0d321	branches/zip: page0zip.c: Add some Valgrind instrumentation.	18 years ago
marko	7d5f2f84da	branches/zip: trx_rollback_or_clean_all_without_sess(): Distinguish recovered transactions from new ones. Until r1594, they were distinguished by trx->sess == NULL. trx_t: Add the bitfield is_recovered. trx_lists_init_at_db_start(): Set trx->is_recovered. trx_create(): Initialize trx->is_recovered = 0. trx_print(): Display information about trx->is_recovered. trx_rollback_or_clean_all_without_sess(): Skip new transactions. Protect all accesses of trx_sys->trx_list with kernel_mutex. trx_roll_crash_recv_trx, trx_roll_max_undo_no, trx_roll_progress_printed_pct: Made these variables static.	18 years ago
marko	b1d3192f45	branches/zip: row_merge_drop_temp_indexes(): Use COMMIT WORK instead of trx_commit_for_mysql().	18 years ago
marko	a877fffcc9	branches/zip: buf_block_get_frame(): Add missing parenthesis.	18 years ago
vasil	0028e8d1ee	branches/zip: Add innodb_locks.lock_data column and some relevant tests. For record locks this column represents the ordering fields of the locked row in a human readable, SQL-valid, format. Approved by: Marko	18 years ago
marko	ef91b93e6d	branches/zip: Minor performance tuning based on measurement data on mispredicted branches: opcontrol --event=BR_CND_MISSP_EXEC:45000 UT_SORT_FUNCTION_BODY(): Copy the array with memcpy(3). cmp_dtuple_rec_with_match(), cmp_rec_rec_with_match(), cmp_debug_dtuple_rec_with_match(): Add UNIV_UNLIKELY hints around tests for REC_INFO_MIN_REC_FLAG.	18 years ago
marko	fca2f0c678	branches/zip: Reduce WAIT_FOR_READ from 20 to 5 milliseconds, to correspond to the time in which modern disks can serve a random disk read.	18 years ago
marko	9f7cad3268	branches/zip: Add UNIV_UNLIKELY hints to help branch prediction.	18 years ago
marko	fcd34fa208	branches/zip: buf_pool_t: Add n_pend_unzip. Display it in buf_print().	18 years ago
marko	d7deb7fc2e	branches/zip: buf_page_get_gen(): Improve the comments about wait_until_unfixed.	18 years ago
marko	8bee0c8358	branches/zip: buf_pool_init(): Allocate buf_pool with mem_zalloc().	18 years ago
marko	6b3be8a613	branches/zip: buf_page_get_gen(): Reinitialize guess when re-entering the loop.	18 years ago
vasil	806d940575	branches/zip: Change mach_read_int_type() to return an integer type (ullint) instead of array of bytes that later needs to be converted to an appropriate integer type. Approved by: Sunny	18 years ago
vasil	51f09f6447	branches/zip: Make lock_get_type_str() to also indicate if it is a gap lock. Suggested by: Heikki Approved by: Marko	18 years ago
marko	5e57a1ae83	branches/zip: Add the function dtype_is_utf8().	18 years ago
marko	2eb32d30b5	branches/zip: Minor cleanup. log_block_calc_checksum(), log_block_get_checksum(): Add const qualifiers. log_block_calc_checksum(): Split a long expression to more readable chunks. Some compilers might optimize this better.	18 years ago
marko	43becedf54	branches/zip: Cast void* pointers to byte* when doing pointer arithmetics.	18 years ago
marko	0d6bfafd6c	branches/zip: Merge 1937:2015 from trunk.	18 years ago
marko	03fcaeec56	branches/zip: Remove some unnecessary memory references in the master thread. srv_print_thread_releases, srv_print_lock_waits, srv_print_buf_io, srv_print_log_io, srv_print_latch_waits: Define these variables as constants (FALSE), unless UNIV_DEBUG is defined. These variables are never assigned to, and they are initialized to FALSE. It could be useful to set them when debugging InnoDB. srv_slot_t: Fuse the fields type, in_use, suspended to a single machine word. srv_meter[], srv_meter_low_water[], srv_meter_high_water[], srv_meter_high_water2[], srv_meter_foreground[]: Enclose these arrays inside #if 0. The arrays are essentially constants that do not affect the control flow. enum srv_thread_type: New enum, to replace the #defines SRV_COM, ... Enclose the unused values SRV_BUFFER, SRV_RECOVERY, SRV_INSERT inside #if 0, so that some arrays and loops can be reduced.	18 years ago
marko	7ebd4af72f	branches/zip: row_build_index_entry(): Correct a typo made in r2012.	18 years ago
marko	996edd8a91	branches/zip: Do not access the fields of dfield_t directly. dfield_dup(): New function for duplicating the data pointed to by dfield_t. dfield_set_len(), dfield_set_data(): Add Valgrind instrumentation.	18 years ago
marko	1033dbfb60	branches/zip: row_rec_to_index_entry_low(): Remove a bogus assertion.	18 years ago
marko	1a1c987ba5	branches/zip: Fix bugs that were introduced in r1591. row_upd_rec_in_place(): Correct a debug assertion. row_upd_index_parse(): Initialize new_val with dfield_set_data() or dfield_set_null(). This ensures that new_val->ext is initialized.	18 years ago
marko	5e9ec7afb6	branches/zip: When seeking to a different B-tree page, update the cached value of the block that the cursor points to. row_ins_check_foreign_constraint(): Call btr_pcur_get_block() after row_ins_foreign_check_on_constraint(), as it may reposition the cursor on a different page. row_ins_scan_sec_index_for_duplicate(): Call btr_pcur_get_block() on every iteration of the loop. Use do ... while instead of for (;;).	18 years ago
marko	cd12974298	branches/zip: Minor cleanup of B-tree cursor operations. btr_pcur_get_rel_pos(): Add a const qualifier. btr_pcur_get_btr_cur(), btr_pcur_get_page_cur(): btr_cur_get_page_cur(): Define as const-preserving macros. btr_pcur_is_on_user_rec(), btr_pcur_is_after_last_on_page(), btr_pcur_is_before_first_on_page(): Remove the unused parameter mtr.
