InnoDB depends on some MySQL internals which other plugins should not
26
need. This is because of InnoDB's foreign key support, "safe" binlog
27
truncation, and other similar legacy features.
29
We define accessors for these internals unconditionally, but do not
30
expose them in mysql/plugin.h. They are declared in ha_innodb.h for

The macros below are borrowed from include/linux/compiler.h in the
63
Linux kernel. Use them to indicate the likelyhood of the truthfulness
64
of a condition. This serves two purposes - newer versions of gcc will be
65
able to optimize for branch predication, which could yield siginficant
66
performance gains in frequently executed sections of the code, and the
67
other reason to use them is for documentation

The macros below are useful in optimising places where it has been
80
discovered that cache misses stall the process and where a prefetch
81
of the cache line can improve matters. This is available in GCC 3.1.1
83
PREFETCH_READ says that addr is going to be used for reading and that
84
it is to be kept in caches if possible for a while
85
PREFETCH_WRITE also says that the item to be cached is likely to be
87
The *LOCALITY scripts are also available for experimentation purposes
88
mostly and should only be used if they are verified to improve matters.

Solaris 9 include file <sys/feature_tests.h> refers to X/Open document
161
System Interfaces and Headers, Issue 5
163
saying we should define _XOPEN_SOURCE=500 to get POSIX.1c prototypes,
164
but apparently other systems (namely FreeBSD) don't agree.
166
On a newer Solaris 10, the above file recognizes also _XOPEN_SOURCE=600.
167
Furthermore, it tests that if a program requires older standard
168
(_XOPEN_SOURCE<600 or _POSIX_C_SOURCE<200112L) it cannot be
169
run on a new compiler (that defines _STDC_C99) and issues an #error.
170
It's also an #error if a program requires new standard (_XOPEN_SOURCE=600
171
or _POSIX_C_SOURCE=200112L) and a compiler does not define _STDC_C99.
173
To add more to this mess, Sun Studio C compiler defines _STDC_C99 while
174
C++ compiler does not!
176
So, in a desperate attempt to get correct prototypes for both
177
C and C++ code, we define either _XOPEN_SOURCE=600 or _XOPEN_SOURCE=500
178
depending on the compiler's announced C standard support.
180
Cleaner solutions are welcome.
