Sunny Bains	b37256b1ab	Fix bug# 55543 - InnoDB Plugin: Signal 6: Assertion failure in file fil/fil0fil.c line 4306 The bug is due to a double delete of a BLOB, once via: rollback -> btr_cur_pessimistic_delete() and the second time via purge. The bug is in row_upd_clust_rec_by_insert(). There we relinquish ownership of the non-updated BLOB columns in btr_cur_mark_extern_inherited_fields() before building the row entry that will be inserted and whose contents will be logged in the UNDO log. However, we don't set the BLOB column later to INHERITED so that a possible rollback will not free the original row's non-updated BLOB entries. This is because the condition that checks for that is in : if (node->upd_ext) {}. node->upd_ext is non-NULL only if a BLOB column was updated and that column is part of some key ordering (see row_upd_replace()). This results in the non-update BLOB columns being deleted during a rollback and subsequently by purge again. rb://413	15 years ago

Davi Arnaut	11fae04527	Bug#45288: pb2 returns a lot of compilation warnings on linux Although the C standard mandates that sprintf return the number of bytes written, some very ancient systems (i.e. SunOS 4) returned a pointer to the buffer instead.

Davi Arnaut	cd37b73fe5	Bug#53445: Build with -Wall and fix warnings that it generates Introduce a MySQL maintainer/developer mode that enables a set of warning options for the C/C++ compiler. This mode is intended to help improve the overall quality of the code. The warning options are: C_WARNINGS="-Wall -Wextra -Wunused -Wwrite-strings -Werror" CXX_WARNINGS="$C_WARNINGS -Wno-unused-parameter" Since -Wall is essentially a moving target, autoconf checks are not run with warning options enabled, in particualr -Werror. This decision might be revisited in the future. The patch also fixes a mistake in the makefiles, where automake CXXFLAGS would be set to CFLAGS. config/ac-macros/maintainer.m4: Add a set of default compiler flags used when in maintainer mode. configure.in: Hook into the maintainer mode. Disabled by default.	16 years ago

Marko Mäkelä	707a3bef6e	Correct some comments that were added in the fix of Bug #54358 (READ UNCOMMITTED access failure of off-page DYNAMIC or COMPRESSED columns). Records that lack incompletely written externally stored columns may be accessed by READ UNCOMMITTED transaction even without involving a crash during an INSERT or UPDATE operation. I verified this as follows. (1) added a delay after the mini-transaction for writing the clustered index 'stub' record was committed (patch attached) (2) started mysqld in gdb, setting breakpoints to the where the assertions about READ UNCOMMITTED were added in the bug fix (3) invoked ibtest3 --create-options=key_block_size=2 to create BLOBs in a COMPRESSED table (4) invoked the following: yes 'set transaction isolation level read uncommitted; checksum table blobt3;select sleep(1);'\|mysql -uroot test (5) noted that one of the breakpoints was triggered (return(NULL) in btr_rec_copy_externally_stored_field()) === modified file 'storage/innodb_plugin/row/row0ins.c' --- storage/innodb_plugin/row/row0ins.c 2010-06-30 08:17:25 +0000 +++ storage/innodb_plugin/row/row0ins.c 2010-06-30 08:17:25 +0000 @@ -2120,6 +2120,7 @@ function_exit: rec_t* rec; ulint* offsets; mtr_start(&mtr); + os_thread_sleep(5000000); btr_cur_search_to_nth_level(index, 0, entry, PAGE_CUR_LE, BTR_MODIFY_TREE, &cursor, 0, === modified file 'storage/innodb_plugin/row/row0upd.c' --- storage/innodb_plugin/row/row0upd.c 2010-06-30 08:11:55 +0000 +++ storage/innodb_plugin/row/row0upd.c 2010-06-30 08:11:55 +0000 @@ -1763,6 +1763,7 @@ row_upd_clust_rec( rec_offs_init(offsets_); mtr_start(mtr); + os_thread_sleep(5000000); ut_a(btr_pcur_restore_position(BTR_MODIFY_TREE, pcur, mtr)); rec = btr_cur_get_rec(btr_cur);	16 years ago

Marko Mäkelä	62084feb55	Bug#54358: READ UNCOMMITTED access failure of off-page DYNAMIC or COMPRESSED columns When the server crashes after a record stub has been inserted and before all its off-page columns have been written, the record will contain incomplete off-page columns after crash recovery. Such records may only be accessed at the READ UNCOMMITTED isolation level or when rolling back a recovered transaction in recv_recovery_rollback_active(). Skip these records at the READ UNCOMMITTED isolation level. TODO: Add assertions for checking the above assumptions hold when an incomplete BLOB is encountered. btr_rec_copy_externally_stored_field(): Return NULL if the field is incomplete. row_prebuilt_t::templ_contains_blob: Clarify what "BLOB" means in this context.

Davi Arnaut	0eb26fdfa8	Bug#53445: Build with -Wall and fix warnings that it generates Apart strict-aliasing warnings, fix the remaining warnings generated by GCC 4.4.4 -Wall and -Wextra flags. One major source of warnings was the in-house function my_bcmp which (unconventionally) took pointers to unsigned characters as the byte sequences to be compared. Since my_bcmp and bcmp are deprecated functions whose only difference with memcmp is the return value, every use of the function is replaced with memcmp as the special return value wasn't actually being used by any caller. There were also various other warnings, mostly due to type mismatches, missing return values, missing prototypes, dead code (unreachable) and ignored return values. BUILD/SETUP.sh: Remove flags that are implied by -Wall and -Wextra. Do not warn about unused parameters in C++. BUILD/check-cpu: Print only the compiler version instead of verbose banner. Although the option is gcc specific, the check was only being used for GCC specific checks anyway. client/mysql.cc: bcmp is no longer defined. client/mysqltest.cc: Pass a string to function expecting a format string. Replace use of bcmp with memcmp. cmd-line-utils/readline/Makefile.am: Always define _GNU_SOURCE when compiling GNU readline. Required to make certain prototypes visible. cmd-line-utils/readline/input.c: Condition for the code to be meaningful. configure.in: Remove check for bcmp. extra/comp_err.c: Use appropriate type. extra/replace.c: Replace use of bcmp with memcmp. extra/yassl/src/crypto_wrapper.cpp: Do not ignore the return value of fgets. Retrieve the file position if fgets succeed -- if it fails, the function will bail out and return a error. extra/yassl/taocrypt/include/blowfish.hpp: Use a single array instead of accessing positions of the sbox_ through a subscript to pbox_. extra/yassl/taocrypt/include/runtime.hpp: One definition of such functions is enough. extra/yassl/taocrypt/src/aes.cpp: Avoid potentially ambiguous conditions. extra/yassl/taocrypt/src/algebra.cpp: Rename arguments to avoid shadowing related warnings. extra/yassl/taocrypt/src/blowfish.cpp: Avoid potentially ambiguous conditions. extra/yassl/taocrypt/src/integer.cpp: Do not define type within a anonymous union.

Remove unused code. extra/yassl/taocrypt/src/twofish.cpp: Avoid potentially ambiguous conditions. extra/yassl/testsuite/test.hpp: Function must have C language linkage. include/m_string.h: Remove check which relied on bcmp being defined -- they weren't being used as bcmp is only visible when _BSD_SOURCE is defined. include/my_bitmap.h: Remove bogus helpers which were used only in a few files and were causing warnings about dead code. include/my_global.h: Due to G++ bug, always silence false-positive uninitialized variables warnings when compiling C++ code with G++. Remove bogus helper. libmysql/Makefile.shared: Remove built-in implementation of bcmp. mysql-test/lib/My/SafeProcess/safe_process.cc: Cast pid to largest possible type for a process identifier. mysys/mf_loadpath.c: Leave space of the ending nul. mysys/mf_pack.c: Replace bcmp with memcmp. mysys/my_bitmap.c: Dead code removal. mysys/my_gethwaddr.c: Remove unused variable. mysys/my_getopt.c: Silence bogus uninitialized variable warning.

Sunny Bains	7299858763	Fix bug#54583. This change reverses rsvn:1350 by getting rid of a bogus assertion and clarifies the invariant in dict_table_get_on_id(). In Mar 2007 Marko observed a crash during recovery, the crash resulted from an UNDO operation on a system table. His solution was to acquire an X lock on the data dictionary, this in hindsight was an overkill. It is unclear what caused the crash, current hypothesis is that it was a memory corruption. The X lock results in performance issues by when undoing changes due to rollback during normal operation on regular tables. Why the change is safe: ====================== The InnoDB code has changed since the original X lock change was made. In the new code we always lock the data dictionary in X mode during startup when UNDOing operations on the system tables (this is a given). This ensures that the crash Marko observed cannot happen as long as all transactions that update the system tables follow the standard rules by setting the appropriate DICT_OP flag when writing the log records when they make the changes. If transactions violate the above mentioned rule then during recovery (at startup) the rollback code (see trx0roll.c) will not acquire the X lock and we will see the crash again. This will however be a different bug.	16 years ago
