Problem: some call of INET_NTOA() function may lead
to a crash due to missing its character set initialization.
Fix: explicitly set the character set.
mysql-test/r/func_misc.result:
Fix for bug#57283: inet_ntoa() crashes
- test result.
mysql-test/t/func_misc.test:
Fix for bug#57283: inet_ntoa() crashes
- test case.
sql/item_strfunc.cc:
Fix for bug#57283: inet_ntoa() crashes
- explicitly set buffer's character set.
Problem: if multibyte and binary string arguments passed to
RPAD(), LPAD() or INSERT() functions, they might return
wrong results or even lead to a server crash due to missed
character set convertion.
Fix: perform the convertion if necessary.
mysql-test/r/ctype_utf8.result:
Fix for bug#57272: crash in rpad() when using utf8
- test result.
mysql-test/t/ctype_utf8.test:
Fix for bug#57272: crash in rpad() when using utf8
- test case.
sql/item_strfunc.cc:
Fix for bug#57272: crash in rpad() when using utf8
- convert multibyte argument's character set to binary in case of
FUNCTION(MULTIBYTE_ARG, .., BINARY_ARG,..) for RPAD(), LPAD() and
INSERT() functions.
No mysql-test case. Tested by creating a table, removing a *.frm file and
attempting to create the table again. Code coverage tested by
instrumentation. Tested with Valgrind.
- fix ~20 warnings about redefinition of HAVE_DLOPEN
This was caused by new ADD_DEFINITIONS(-DHAVE_DLOPEN) inside client library CMakeLists.txt
- fix dlerror() message which ("static build?" ) which is only confusing on Windows,
there is no "static build"
The error was introduced by typo in variable name (errormsg instead of correct
errmsg)
- Also, precache HAVE_PEERCRED to OFF in cmake\os\WindowsCache.cmake
(to avoid useless system check).
- Also, add missing check for errors from FormatMessage().
- Also, remove annoying CMake debug printout of MALLOC_LIB if this is not set.
connectors plugins
Implemented changes needed to keep the client plugin API compatible with
the existing plugins :
1. Provided an options() client plugin API to let the application pass
options to the plugin after loading it
2. Added "License" (const char *) to specify the client plugin's license
3. Added "mysql_api" as a placeholder that the client library can use
to pass function pointers to the plugin so that the plugin can call the
C lib back.
4. Updated the existing client plugins to comply with the API change.
5. Added more detailed error message generation for Windows.
Quoting from the bug report:
The pstack library has been included in MySQL since version
4.0.0. It's useless and should be removed.
Details: According to its own documentation, pstack only works
on Linux on x86 in 32 bit mode and requires LinuxThreads and a
statically linked binary. It doesn't really support any Linux
from 2003 or later and doesn't work on any other OS.
