* Bug#34043: Server loops excessively in _checkchunk() when safemalloc is enabledDavi Arnaut2010-07-083-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Another incarnation of the patch for Bug#30708Alexander Nozdrin2010-05-191-3/+0

* | Bug#51607: Automake distcheck target broken.Vladislav Vaintroub2010-03-091-2/+3
|/ | | | | | | | | Reason for the error was that ./configure wrapper script was not safe for VPATH builds used by "make distcheck", specifically it expected configure.am to be in the current directory. Fix changes configure wrapper to resolve script names relative to configure script path. Also, use $top_srcdir/configure.am instead of configure.am in dist-hook to be more VPATH friendly.

| | | | | | | | | | configure wrapper. The bug was that ./configure was passing paramers to subscripts as $@, and to handle embedded spaces it needs to be quoted as "$@". This resulting into a bug when ./configure was called e.g with CFLAGS='-m64 -Xstrconst'.. Additionally, fixed cmake/configure.pl did not handle environment variables passed on the command line. this is fixed in this push

|/ / | | | | | | | | | | | | | | | | | | | | | | The convert_constant_item function converts a constant to integer using field for condition like 'field = a_constant'. In some cases the convert_constant_item is called for a subquery when outer select is already being executed, so convert_constant_item saves field's value to prevent its corruption. For EXPLAIN and at the prepare phase field's value isn't initialized yet, thus when convert_constant_item tries to restore saved value it fails assertion. Now the convert_constant_item doesn't save/restore field's value if it's haven't been read yet. Outer constant values are always saved.
