Resolving a stacktrace including functions in dynamic libraries requires
us to look inside the libraries for the symbols. Addr2line needs to be
started with the correct binary for each address on the stack. To do this,
figure out which library it is using dladdr, then if the addr2line
binary was started with a different binary, fork it again with the
correct one.
We only have one addr2line process running at any point during the
stacktrace resolving step. The maximum number of forks for addr2line should
generally be around 6.
One for server stacktrace code, one for plugin code, one when going back
into server code, one for pthread library, one for libc, one for the
_start function in the server. More can come up if plugin calls server
function which goes back to a plugin, etc.
Check for readline before checking for curses headers, because
MYSQL_CHECK_READLINE fails when curses is not found, but
CHECK_INCLUDE_FILES simply remembers the fact and continues. So if
there's no curses, MYSQL_CHECK_READLINE will abort, the user will then
installs curses and continue the build. Thus, CHECK_INCLUDE_HEADERS
will remember that there is no curses, but other checks from
MYSQL_CHECK_READLINE will remember that curses are there. It will
result in inconsistent HAVE_xxx defines.
1. check that unused inline functions are removed
2. only allow compilation if they are or if the check if overridden
3. with CMAKE_GENERATOR=Makefiles, use all flags when testing
(e.g. both CMAKE_C_FLAGS and CMAKE_C_FLAGS_DEBUG if
CMAKE_BUILD_TYPE=Debug). This is because
- on Solaris with the SunPro compiler, default CMAKE_C_FLAGS_xxx
values contain -xO2 (for Release and RelWithDebInfo)
and -g (for RelWithDebInfo and Debug)
- proper inlining only works at -xO4 without -g
- so if CMAKE_C_FLAGS has -xO4, inlining would work in
configure.cmake (before this fix) and fail during actual compilation
also remove the outdated check for inline from myu_global.h
cherry-pick f1daf9ce from 10.0 branch
-------------------------------------
Fix build failures caused by new C runtime library
- isnan, snprintf, struct timespec are now defined, attempt to
redefine them leads
- P_tmpdir, tzname are no more defined
- lfind() and lsearch() in lf_hash.c had to be renamed, declaration
conflicts with some C runtime functions with the same name declared in
a header included by stdlib.h
Also fix couple of annoying warnings :
- remove #define NOMINMAX from config.h to avoid "redefined" compiler
warnings(NOMINMAX is already in compile flags)
- disable incremental linker in Debug as well (feature not used much
and compiler crashes often)
Also simplify package building with Wix, require Wix 3.9 or later
(VS2015 is not compatible with old Wix 3.5/3.6)
The check for UCONTEXT in cmake was somehow become broken, disabling the
fallback to ucontext. This caused the non-blocking client API to not be
available for non-x86 platforms, on which no hand-crafted assembler
implementation of my_context is available.
- Added some extra command to rpl_start_stop to ensure that the
IO thread has connected to the master before we shut down the server.
- if signal returns signalhandler_t, use this with the alarm code
- Added missing tests to sys_vars
- Fixed some possible overflow bugs in tabxml.cpp

in cmake tests let's treat clang like gcc (same options,
same builtins) in many cases.
* don't check the compiler when
* testing for -fvisibility=hidden support
* testing for HAVE_ABI_CXA_DEMANGLE
* testing for HAVE_GCC_ATOMIC_BUILTINS
* when removing options with string(replace)
* when running ${CC} --version (ignore the error instead)
* run ABI checks for clang
* use "canonical" gcc flags for clang
* fix groonga too
Also:
* add cmake detection for gcc __atomic_* builtins. they might be
supported (__ATOMIC_SEQ_CST is defined), but not for all operand
sizes. In particular, 64-bit atomic load is problematic on i386
* cache check results for Windows
* remove the test for HAVE_CXXABI_H (HAVE_ABI_CXA_DEMANGLE is
suffifient)
Bug#17959689: MAKE GCC AND CLANG GIVE CONSISTENT COMPILATION WARNINGS
Bug#18313717: ENABLE -WERROR IN MAINTANER MODE WHEN COMPILING WITH CLANG
Bug#18510941: REMOVE CMAKE WORKAROUNDS FOR OLDER VERSIONS OF OS X/XCODE
Backport from mysql-5.6 to mysql-5.5
Non-blocking client currently can be build on Windows, GCC on i386 and x64, or any OS wth ucontext.h header. Prior to this patch, build failed if neither of these conditions is true.
Fix to avoid compiler errors in these case - non-blocking API would not be useful on , but otherwise everything will work as before.
- Fixed that wait_timeout_func and wait_timeout tests works on solaris
- We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO).
- Fixed that compile-solaris-amd64-debug works (before that we got a wrong ELF class: ELFCLASS64 on linkage)
- Fixed some compiler warnings
- Fixed some failing tests
BUILD/compile-solaris-amd64-debug:
Fixed that compile-solaris-amd64-debug works (before that we got a wrong ELF class: ELFCLASS64 on linkage)
configure.cmake:
We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO)
mysql-test/suite/parts/t/partition_basic_innodb.test:
Mark test as big test (as otherwise we get timeout on our opensolaris machine in buildbot)
mysql-test/suite/rpl/t/rpl_cant_read_event_incident.test:
Remove warning
Solaris fixes:
- Fixed that wait_timeout_func and wait_timeout tests works on solaris
- We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO).
- Fixed that compile-solaris-amd64-debug works (before that we got a wrong ELF class: ELFCLASS64 on linkage)
- Added missing sync_with_master
Other bug fixes:
- Free memory for rpl_global_gtid_binlog_state before exit() to avoid 'accessing uninitalized mutex' error.
BUILD/FINISH.sh:
Fixed issues on Solaris with ksh
BUILD/compile-solaris-amd64-debug:
Added missing -m64 flag
configure.cmake:
We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO)
mysql-test/suite/rpl/t/rpl_gtid_mdev4473.test:
- Added missing sync_with_master (fix by knielsen)
sql-common/client.c:
Added () to get rid of compiler warning
sql/item_strfunc.cc:
Fixed compiler warning
sql/log.cc:
Free memory for static variable rpl_global_gtid_binlog_state before exit()
- If we are compiling with safemalloc, we would try to call sf_free() for some members after sf_terminate() was called, which would result of trying to access the uninitalized mutex 'sf_mutex'
sql/multi_range_read.cc:
Fixed compiler warnings of converting double to ulong.
sql/opt_range.cc:
Fixed compiler warnings of converting double to ulong or uint
- Better to have all variables that can be number of rows as 'ha_rows'
sql/rpl_gtid.cc:
Added rpl_binlog_state::free() to be able to free memory for static objects before exit()
sql/rpl_gtid.h:
Added rpl_binlog_state::free() to be able to free memory for static objects before exit()
sql/set_var.cc:
Fixed compiler warning
sql/sql_join_cache.cc:
Fixed compiler warnings of converting double to uint
sql/sql_show.cc:
Added cast to get rid of compiler warning
sql/sql_statistics.cc:
Remove code that didn't do anything.
(store_record() with record[0] is a no-op)
storage/xtradb/os/os0file.c:
Added __attribute__ ((unused))
support-files/compiler_warnings.supp:
Ignore warnings from atomic_add_64_nv
(was not able to fix this with a cast as the macro is a bit different between systems)
vio/viosocket.c:
Added more DBUG_PRINT
The check for unsigned time_t failed, on all platforms, due to missing #include.
from CMakeFiles/CMakeError.log
with this patch: error: size of array array is negative
without this patch: error: time_t undeclared (first use in this function)
The reason for the error is missing definition for SIGNAL_WITH_IO_CLOSE on this platform
which now needs to always be defined, as in 5.6
On Solaris10 only, this preprocessor constant was not defined, thus code that shutdowns a socket in THD::awake was not executed, and polling thread was not interrupted.
Fix is to always define SIGNAL_WITH_IO_CLOSE, just like MySQL5.6 does.
sql/item_subselect.cc:
Added purecov info
sql/sql_select.cc:
Added cast
storage/innobase/handler/ha_innodb.cc:
Added cast
storage/xtradb/btr/btr0btr.c:
Added buf_block_get_frame_fast() to avoid compiler warning
storage/xtradb/handler/ha_innodb.cc:
Added cast
storage/xtradb/include/buf0buf.h:
Innodb has buf_block_get_frame(block) defined as (block)->frame.
Didn't want to do a big change to break xtradb as it may use block_get_frame() differently, so I mad this quick hack to patch one compiler warning.
cmake/maintainer.cmake:
Add -DFORCE_INIT_OF_VARS to not get warnings generated by -Wall
configure.cmake:
Don't add -Wall if we already have it. This is to not enable options that are already turned off.
support-files/compiler_warnings.supp:
Removed suppression that is not needed anymore
