c4c94ea0ac Bug#42054: SELECT CURDATE() is returning bad value
The problem from a user point of view was that on Solaris the
time related functions (e.g. NOW(), SYSDATE(), etc) would always
return a fixed time.

This bug was happening due to a logic in the time retrieving
wrapper function which would only call the time() function every
half second. This interval between calls would be calculated
using the gethrtime() and the logic relied on the fact that time
returned by it is monotonic.

Unfortunately, due to bugs in the gethrtime() implementation,
there are some cases where the time returned by it can drift
(See Solaris bug id 6600939), potentially causing the interval
calculation logic to fail.

The solution is to retrieve the correct time whenever a drift in
the time returned by gethrtime() is detected. That is, do not
use the cached time whenever the values (previous and current)
returned by gethrtime() are not monotonically increasing.

mysys/my_getsystime.c:
  Do not used the cached time if gethrtime is not monotonic.

998065c3a6 Bug#51023: Mysql server crashes on SIGHUP and destroys InnoDB files
From a user perspective, the problem is that a FLUSH LOGS or SIGHUP
signal could end up associating the stdout and stderr to random
files. In the case of this bug report, the streams would end up
associated to InnoDB ibd files.

The freopen(3) function is not thread-safe on FreeBSD. What this
means is that if another thread calls open(2) during freopen()
is executing that another thread's fd returned by open(2) may get
re-associated with the file being passed to freopen(3). See FreeBSD
PR number 79887 for reference:

  http://www.freebsd.org/cgi/query-pr.cgi?pr=79887

This problem is worked around by substituting a internal hook within
the FILE structure. This avoids the loss of atomicity by not having
the original fd closed before its duplicated.

Patch based on the original work by Vasil Dimov.

include/my_sys.h:
  Export my_freopen.
mysys/my_fopen.c:
  Add a my_freopen abstraction to workaround bugs in specific OSes.
  Add a prototype for getosreldate() as older FreeBSD versions did
  not define one.
sql/log.cc:
  Move freopen abstraction code over to mysys.
  The streams are now only reopened for writing.

e63b5546c5 Implementation of MWL#172: Add support for prepared statements to HANDLER READ
It includes speed optimizations for HANDLER READ by caching as much as possible in HANDLER OPEN
Other things:
- Added mysqld option --disable-thr-alarm to be able to benchmark things without thr_alarm
- Changed 'Locked' state to 'System lock' and 'Table lock' (these where used in the code but never shown to end user)

- Moved handler function prototypes to sql_handler.h
- Remove not anymore used 'thd->locked' member


include/thr_alarm.h:
  Added my_disable_thr_alarm

0eae06c430 Bug#473914: mysql_client_test fail with in debug compilaton on windows x64
Reason: inconsistent compilation, federatedx is compiled without SAFEMALLOC
flag, while anything else is compiled with SAFEMALLOC.

As a consequence, my_hash_init used inside federatedx initialization does not
provide correct caller info parameters (file, line) , so they are initialized with 
whatever is on stack. When info about allocated memory is output in
COM_DEBUG command, the server crashes trying to output string starting at
0xcccccccccccccccc.

The fix is to remove SAFEMALLOC  preprocessor flags 
from every CMakeLists.txt, except the top-level one.

Also, SAFEMALLOC is not defined by default now, instead
there is WITH_DEBUG_FULL CMake option which adds 
-DSAFEMALLOC to C and C++ flags in debug compilation. 
This option is off by  default, because 
1) Debug C runtime already has heap debugging builtin with 
 overwrite and leak detection
2)safemalloc considerably slows down the tests.


Note also  that 
- SAFEMALLOC is gone  in MySQL5.5
- On Windows, heap related overflows can also be found using free pageheap utility
(that is also part of application verifier). This is even more efficient if there are no other layers 
on top of Windows heap allocator, e.g  it is most efficient with release version.

- Fixed problem with oqgraph and 'make dist'

Note that after this merge we have a problem show in join_outer where we examine too many rows in one specific case (related to BUG#57024).
This will be fixed when mwl#128 is merged into 5.3.

cd504e49bc Workaround a GCC warning about a pointer being cast to a larger
integral type. Use intptr which is designed to hold pointer values
and pass it to off_t.

mysys/stacktrace.c:
  Add a compile time assert to ensure that off_t is large enough
  to hold the pointer value.

d5e928959e Bug#51817: incorrect assumption: thd->query at 0x2ab2a8360360 is an invalid pointer
The problem is that the logic which checks if a pointer is
valid relies on a poor heuristic based on the start and end
addresses of the data segment and heap.

Apart from miscalculating the heap bounds, this approach also
suffers from the fact that memory can come from places other
than the heap. See Bug#58528 for a more detailed explanation.

On Linux, the solution is to access the process's memory
through /proc/self/task/<tid>/mem, which allows for retrieving
the contents of pages within the virtual address space of
the calling process. If a address range is not mapped, a
input/output error is returned.

client/mysqltest.cc:
  Use new interface to my_safe_print_str.
include/my_stacktrace.h:
  Drop name from my_safe_print_str.
mysys/stacktrace.c:
  Access the process's memory through a file descriptor and
  dump the contents of the memory range. The file descriptor
  offset is equivalent to a offset into the address space.
  
  Do not print the name of the variable associated with the
  address. It can be better accomplished at a higher level.
sql/mysqld.cc:
  Put the variable dumping information within its own newline block.
  Use symbolic names which better convey information to the user.

0de9a4abab MWL#74: Shared libmysqld.so library.
Switch makefiles to use libtool to build libmysqld.so, as well as all its
dependencies.

The previous MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() declaration is removed,
as it does not work well with a libtool build. Instead, plugins that need it
can specify an alternate object in MYSQL_PLUGIN_STATIC() that will be used for
embedded library. The plugin must then take care itself of compiling the
special object for embedded, rebuilding the source files previously listed in
MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() with @plugin_embedded_defs@ in
CFLAGS/CXXFLAGS. The extra target @XXX_embedded_static_target@ is available
for the special object, this will be empty when --without-embedded-server.

All in-tree plugins are changed to build their static targets with libtool.
Additional plugins that want to work with libmysqld.so will need to be
similarly modified to build with libtool (or otherwise provide an -fPIC
object). Dynamically loaded plugins are not affected.

The old libraries like libmysys.a, libmyisam.a and similar libraries, which
were installed by `make install` though this is of little use, are still built
and installed to not break package scripts etc. that expect them. These
libraries are kept static to avoid introducing new .so dependencies.

The patch also fixes a handfull of duplicate symbol linker errors, where we
included some object twice during linking; these for one reason or another did
not produce errors before but caused problems on some platforms with this
patch (eg. Mac OS X linker is more strict for shared objects).

This patch only does what is necessary to build libmysqld.so. There are some
more cleanups that are possible now that we are using libtool more fully,
which could done in subsequent patches (though we may not bother as we are
switching from autotools to CMake anyway):

 - In libmysql_r/, we should be able to just link libmysys.la etc, instead of
   symlinking and re-compiling sources into the directory.

 - In libmysql/, we can similarly avoid symlinking and recompiling sources if
   we instead build a libmysys_nothread.la library with appropriate CFLAGS and
   link that.

 - In sql/, we can build a separate target libmysql_int.la with appropriate
   CFLAGS for embedded and use that in libmysqld/ instead of symlinking
   sources.

 - libmysys.a, libmyisam.a and similar libraries could be installed as .so
   also to save on code size; or alternatively could be not installed at all.
