path names than 99 characters, using the USTAR format of the
resulting source TAR.
To be able to specify the use of USTAR when creating the source
TAR, we needed both to update the GNU autotools version requirements
slightly, and update the initiation of the tools to use more
modern constructs.
printstack() being present
When Bug#47391 was fixed, no assumption was made that support
for Solaris 8 was needed. Solaris 8 lacks printstack(), and
the build breaks because of this.
This patch adds a test for the presence of printstack() to
configure.in for 5.0, and uses HAVE_PRINTSTACK to make
decisions rather than the __sun define.
A build "--without-server" fails if using "--with-ssl" (YaSSL)
The problem was the lack of directory "extra" in a build
which did not include the server.
Backport from 6.0 to 5.1.
Only those sync points are included, which are used in debug_sync.test.
The Debug Sync Facility allows to place synchronization points
in the code:
open_tables(...)
DEBUG_SYNC(thd, "after_open_tables");
lock_tables(...)
When activated, a sync point can
- Send a signal and/or
- Wait for a signal
Nomenclature:
- signal: A value of a global variable that persists
until overwritten by a new signal. The global
variable can also be seen as a "signal post"
or "flag mast". Then the signal is what is
attached to the "signal post" or "flag mast".
- send a signal: Assign the value (the signal) to the global
variable ("set a flag") and broadcast a
global condition to wake those waiting for
a signal.
- wait for a signal: Loop over waiting for the global condition until
the global value matches the wait-for signal.
Please find more information in the top comment in debug_sync.cc
or in the worklog entry.
Solaris binary packages should be compiled with '-g0', not '-g'
The main fix for this is done in the build tools,
but in the sources it affects "configure.in"
which sets "DEBUG_CXXFLAGS" to be used in all debug builds.
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()".
The problem was that a pthread.h header used by gcc did not
declare the pthread_setscheprio, yet the function is implemented
by the function is implemented, causing a autoconf check to pass
and compilation with C++ to fail. The solution is to add a
autoconf check to ensure that the function is properly declared.
Change the default optimization level for Sun Studio to "-O1".
This is a workaround for a Sun Studio bug (see bug #41710
comments for details):
1. Use $GCC instead of $ac_cv_prog_gcc to check for gcc, since
the first one is the only documented way to do it.
2. Use $GXX instead of $ac_cv_prog_cxx_g to check for g++,
since the latter is set to "yes" when the C++ compiler accepts
"-g" which is the case for both g++ and CC.
3. When building with Sun Studio, set the default values for
CFLAGS/CXXFLAGS to "-O1", since unlike GCC, Sun Studio
interprets "-O" as "-xO3" (see the manual pages for cc and CC).
produce incorrect results for ROUND()
Added a workaround and a configure check to test whether
isinf() is affected by the GCC bug #39228.
Since no code in MySQL server is currently affected by that
bug, the patch is actually a safeguard for possible future
code modifications. No test cases or changelog entries are
needed.
Both of our own implementations of rint(3) were inconsistent with the
most common behavior of rint() on those platforms that have it: round
to nearest, break ties by rounding to nearest even.
Fixed by leaving just one implementation of rint() in our source tree,
and changing its behavior to match the most common native
implementations on other platforms.
The problem is that MySQL use of pthread_setschedprio is not
supported by i5/OS and the default system behavior for unsupported
calls is to emit a SIGILL signal which causes the server to
abort.
The solution is to treat the pthread_setschedprio as inexistent
when compiling binaries for i5/OS. This also does not invalidate
the fix for bug 38477 as the only supported dispatch class is
SCHED_OTHER (which is passed to pthread_setschedparam).
