Jon Olav Hauglid	b91f134ae1	Bug#13030056 62533: UNITTEST/MYSYS/MY_ATOMIC-T.C DOES NOT COMPILE ON MACOSX LION The problem was that on optimized builds, the wrong code was generated for my_atomic_add64 if a variable argument was optimized away as a constant. This patch fixes the problem by making the variable volatile. Another workaround is to specify architecture explicitly using e.g. CFLAGS/CXXFLAGS= "-m64". No test case added.	14 years ago
Davi Arnaut	017281da24	Bug#12727287: Maintainer mode compilation fails with gcc 4.6 GCC 4.6 has new -Wunused-but-set-variable flag, which is enabled by -Wall, that causes GCC to emit a warning whenever a local variable is assigned to, but otherwise unused (aside from its declaration). Since the maintainer mode uses -Wall and -Werror, source code which triggers these warnings will be rejected. That is, these warnings become hard errors. The solution is to fix the code which triggers these specific warnings. In most of the cases, this is a welcome cleanup as code which triggers this warning is probably dead anyway.	15 years ago
Marc Alff	4075c52b69	Bug#12552516 LF_HASH REQUIRES MY_THREAD_INIT() Before this fix, a thread instrumented for the performance schema, that would perform file io operations, could crash inside the LF_HASH implementation, in cases when my_thread_init is not called. The crash itself has not been reported in 5.5 but similar crashes have been found in 5.6-based development branches, using LF_HASH for more instrumentation. The possibility of a crash in 5.5 is confirmed by code analysis. The problem is that, when my_thread_init() is not called, which can happen for threads in storage engines or thirs party code, my_thread_var is NULL. Using my_thread_var->stacks_ends_here in mysys/lf_alloc-pin.c is unsafe. Given that my_thread_var is used: - only for stacks_ends_here - only on platform with HAVE_ALLOCA - only when there is enough room on the stack and given that the LF_HASH implementation has a fallback algorythm implemented already when using alloca is not possible, using my_thread_var->stacks_ends_here is in fact not a strict requirement, and can be relaxed. The fix is to: - test explicitly if my_thread_var is NULL, to account for cases when my_thread_init() is not used by the calling thread. - not use alloca in this case, and rely on the fall back code already in place. so that the LF_HASH can be supported even without my_thread_init(). The implementation of mysys/lf_alloc-pin.c has been fixed to support this new usage. The units tests in unittest/mysys/lf-t.c have been adjusted accordingly.	15 years ago

Jon Olav Hauglid	d1192eb8ee	Followup to Bug #11752069 (former bug 43152) Assertion `bitmap_is_set_all(&table->s->all_set)' failed in handler::ha_reset This followup fixes the compilation warning 'test_bit' may be used uninitialized in this function introduced by the previous patch.	15 years ago
Jon Olav Hauglid	ba5b97343c	Bug #11752069 (former bug 43152) Assertion `bitmap_is_set_all(&table->s->all_set)' failed in handler::ha_reset This assertion could be triggered if two connections simultaneously executed two bitmap test functions on the same bitmap. For example, the assertion could be triggered if one connection executed UPDATE while a second connection executed SELECT on the same table. Even if bitmap test functions have read-only semantics and have const bitmaps as parameter, several of them modified the internal state of the bitmap. With interleaved execution of two such functions it was possible for one function to modify the state of the same bitmap that the other function had just modified. This lead to an inconsistent state and could trigger the assert. Internally the bitmap uses 32 bit words for storage. Since bitmaps can contain any number of bits, the last word in the bitmap may not be fully used. A 32 bit mask is maintained where a bit is set if the corresponding bit in the last bitmap word is unused. The problem was that several test functions applied this mask to the last word. Sometimes the mask was negated and used to zero out the remainder of the last word and sometimes the mask was used as-is to fill the remainder of the last word with 1's. This meant that if a function first used the negated mask and another function then used the mask as-is (or vice-versa), the first function would then get the wrong result. This patch fixes the problem by changing the implementation of 9 bitmap functions that modified the bitmap state even if the bitmap was declared const. These functions now preserve the internal state of the bitmap. This makes it possible for two connections to concurrently execute two of these functions on the same bitmap without issues. The patch also removes dead testing code from my_bitmap.c. These tests have already been moved to unittest/mysys/bitmap-t.c. Existing test coverage of my_bitmap has been extended. No MTR test case added as this would require adding several sync points to the bitmap functions. The patch has been tested with a non-deterministic test case posted on the bug report.	15 years ago
Davi Arnaut	f6deb00a56	WL#5665: Removal of the autotools-based build system The autotools-based build system has been superseded and is being removed in order to ease the maintenance burden on developers tweaking and maintaining the build system. In order to support tools that need to extract the server version, a new file that (only) contains the server version, called VERSION, is introduced. The file contents are human and machine-readable. The format is: MYSQL_VERSION_MAJOR=5 MYSQL_VERSION_MINOR=5 MYSQL_VERSION_PATCH=8 MYSQL_VERSION_EXTRA=-rc The CMake based version extraction in cmake/mysql_version.cmake is changed to extract the version from this file. The configure to CMake wrapper is retained for backwards compatibility and to support the BUILD/ scripts. Also, a new a makefile target show-dist-name that prints the server version is introduced.	15 years ago

Olav Sandstaa	93e7e5f9d9	Fix for Bug#54478 "mysqld crashes during boot when running mtr with --debug option" The crash during boot was caused by a DBUG_PRINT statement in fill_schema_schemata() (in sql_show.cc). This DBUG_PRINT statement contained several instances of %s in the format string and for one of these we gave a NULL pointer as the argument. This caused the call to vsnprintf() to crash when running on Solaris. The fix for this problem is to replace the call to vsnprintf() with my_vsnprintf() which handles that a NULL pointer is passed as argumens for %s. This patch also extends my_vsnprintf() to support %i in the format string.	15 years ago

Alexander Barkov	e497d6e6e1	Bug#45012 my_like_range_cp932 generates invalid string Problem: The functions my_like_range_xxx() returned badly formed maximum strings for Asian character sets, which made problems for storage engines. Fix: - Removed a number my_like_range_xxx() implementations, which were in fact dumplicate code pieces. - Using generic my_like_range_mb() instead. - Setting max_sort_char member properly for Asian character sets - Adding unittest/strings/strings-t.c, to test that my_like_range_xxx() return well-formed min and max strings. Notes: - No additional tests in mysql/t/ available. Old tests cover the affected code well enough.	16 years ago

Davi Arnaut	3a22d332c7	Bug#22320: my_atomic-t unit test fails Bug#52261: 64 bit atomic operations do not work on Solaris i386 gcc in debug compilation One of the various problems was that the source operand to CMPXCHG8b was marked as a input/output operand, causing GCC to use the EBX register as the destination register for the CMPXCHG8b instruction. This could lead to crashes as the EBX register is also implicitly used by the instruction, causing the value to be potentially garbaged and a protection fault once the value is used to access a position in memory. Another problem was the lack of proper clobbers for the atomic operations and, also, a discrepancy between the implementations for the Compare and Set operation. The specific problems are described and fixed by Kristian Nielsen patches: Patch: 1 Fix bugs in my_atomic_cas(val,cmp,new) that cmp is accessed after CAS succeds. In the gcc builtin implementation, problem was that cmp was read again after atomic CAS to check if old val == cmp; this fails if CAS is successful and another thread modifies cmp in-between. In the x86-gcc implementation, problem was that *cmp was set also in the case of successful CAS; this means there is a window where it can clobber a value written by another thread after successful CAS. Patch 2: Add a GCC asm "memory" clobber to primitives that imply a memory barrier. This signifies to GCC that any potentially aliased memory must be flushed before the operation, and re-read after the operation, so that read or modification in other threads of such memory values will work as intended. In effect, it makes these primitives work as memory barriers for the compiler as well as the CPU. This is better and more correct than adding "volatile" to variables.	16 years ago
Davi Arnaut	a10ae35328	Bug#34043: Server loops excessively in _checkchunk() when safemalloc is enabled Essentially, the problem is that safemalloc is excruciatingly slow as it checks all allocated blocks for overrun at each memory management primitive, yielding a almost exponential slowdown for the memory management functions (malloc, realloc, free). The overrun check basically consists of verifying some bytes of a block for certain magic keys, which catches some simple forms of overrun. Another minor problem is violation of aliasing rules and that its own internal list of blocks is prone to corruption. Another issue with safemalloc is rather the maintenance cost as the tool has a significant impact on the server code. Given the magnitude of memory debuggers available nowadays, especially those that are provided with the platform malloc implementation, maintenance of a in-house and largely obsolete memory debugger becomes a burden that is not worth the effort due to its slowness and lack of support for detecting more common forms of heap corruption. Since there are third-party tools that can provide the same functionality at a lower or comparable performance cost, the solution is to simply remove safemalloc. Third-party tools can provide the same functionality at a lower or comparable performance cost. The removal of safemalloc also allows a simplification of the malloc wrappers, removing quite a bit of kludge: redefinition of my_malloc, my_free and the removal of the unused second argument of my_free. Since free() always check whether the supplied pointer is null, redudant checks are also removed. Also, this patch adds unit testing for my_malloc and moves my_realloc implementation into the same file as the other memory allocation primitives.	16 years ago

Joerg Bruehe	67bcf54df6	Fix bug#46980 Option "--without-server" still not working in 5.1 The general approach is to make sure that source files which require thread support are only compiled if the build really needs thread support, which means when the server is built or a thread-safe client library. This required several changes: - Make sure the subdirectories "storage/" and "plugin/" are only processed if the server is built, not ifclient-only. - Make the compilation of some modules which inherently require threading depend on thread supportin the build. - Separate the handling of threading in "configure.in" from that of server issues, threading is also needed in a non-server build of a thread-safe client library. Also, "libdbug" must get built even in a client-only build, so "dbug/" must be in the list of client directories. In addition, calls to thread functions in source files which can be built without thread support must use the wrapper functions which handle the non-threaded build. So the modules "client/mysqlimport.c" and "client/mysqlslap.c" must call "my_thread_end()" only via "mysql_thread_end()".	16 years ago
