DISCARD TABLESPACE or if the .ibd file is missing for some other reason. ibd_file_missing and tablespace_discarded are manipulated only in row_discard_tablespace_for_mysql() and in row_import_tablespace_for_mysql() and the manipulation is protected/surrounded by row_mysql_lock_data_dictionary()/row_mysql_unlock_data_dictionary() thus we do the same in ha_innobase::info() when checking the values of those members to avoid race conditions.

The fix for bug# 38839 triggered this bug. When the offset and increment are > 1 we need to calculate the next value taking into consideration the two variables. Previously we simply assumed they were 1 particularly offset was never used. MySQL does its own calculation and that's probably why it seemed to work in the past. We would return what we thought was the correct next value and then MySQL would recalculate the actual value from that and return it to the caller (e.g., handler::write_row()). Several new tests have been added that try and catch some edge cases. The tests exposed a wrap around error in MySQL next value calculation which was filed as bug#39828. The tests will need to be updated once MySQL fix that bug. One good side effect of this fix is that dict_table_t size has been reduced by 8 bytes because we have moved the autoinc_increment field to the row_prebuilt_t structure. See review-board for a detailed discussion. rb://3 ------------------------------------------------------------------------

Change the patch to fix the failing mysql-test index_merge_innodb. The previous variant is inappropriate because myisam results are different (2 instead of 4) and then the index_merge_myisam test fails.

fields that are related to the records stored in the page. page_zip_copy() is a fall-back method in certain B-tree operations (tree compression, splitting or merging nodes). The contents of a page may fit in the compressed page frame when it has been modified in a certain sequence, but not when the page is recompressed. Sometimes, copying all or part of the records to an empty page could fail because of compression overflow. In such cases, we copy the compressed and uncompressed pages bit for bit and delete any unwanted records from the copy. (Deletion is guaranteed to succeed.) The method page_zip_copy() is invoked very rarely. In one case, page_zip_copy() was called in btr_lift_page_up() to move the records to the root page of the B-tree. Because page_zip_copy() copied all B-tree page header fields, it overwrote the file segment header fields PAGE_BTR_SEG_LEAF and PAGE_BTR_SEG_TOP. This is the probable cause of the corruption that was reported as Mantis issue #63 and others.

The memory leak was due to wrong parameters passed into VirtualFree() call. So, the call fails with Windows error 87. MEM_DECOMMIT can NOT be used along with MEM_RELEASE. And if the parameter is MEM_RELEASE, the size parameter must be 0. The function frees the entire region that is reserved in the initial allocation call to VirtualAlloc. This issue was introduced by r984. Approved by: Heikki (on IM)

ha_thd() whenever possible. EQ_CURRENT_THD(thd): New predicate, for use in assertions. innobase_drop_database(): Tolerate current_thd == NULL, so that the Windows plugin will work. In the Windows plugin, it will be impossible to skip foreign key checks in this function. However, DROP DATABASE will drop each table (that MySQL knows about) individually before calling this function. Thus, the foreign key checks can be disabled also in the Windows plugin, unless some .frm files are missing.

the maximum record size will never exceed the B-tree page size limit. For uncompressed tables, there should always be enough space for two records in an empty B-tree page. For compressed tables, there should be enough space for storing two node pointer records or one data record in an empty page in uncompressed format. dict_build_table_def_step(): Remove the inaccurate check for table row size. dict_index_too_big_for_tree(): New function: check if the index records would be too big for a B-tree page. dict_index_add_to_cache(): Add the parameter "strict". Invoke dict_index_too_big_for_tree() if it is set. trx_is_strict(), thd_is_strict(): New functions, for determining if innodb_strict_mode is enabled for the current transaction. dict_create_index_step(): Pass the new parameter strict of dict_index_add_to_cache() as trx_is_strict(trx). All other callers pass it as FALSE. innodb.test: Enable innodb_strict_mode before attempting to create a table with a too big record size. innodb-zip.test: Remove the test of inserting random data. Add tests for checking that the maximum record lengths are enforced at table creation time.
