As described in the bug, the problem is not new in 5.4, but newly tickled.
We need a register whose lower 8 bits can be accessed, and must request
such from the assembler. Using a "q" constraint instead of "r" constraint
accomplishes this.
include/Makefile.am: use @PERL@ to call scripts/dheadgen.pl - don't rely on #! /usr/bin/perl
scripts/dheadgen.pl: use 2-arg open() for compatibility with older Perl versions

Bug#34309: '_PC' macro redefinition
For reasons that are now a mystery, we had defined a CPP symbol to
help ancient compilers work better (in some way that's lost to history).
This interferes with at least one modern compiler.
Now, don't define the _PC symbol. Those other underscore-leading
symbols are suspect also, but at least the names aren't inscrutable.
Let's leave them for now.
The problem was that new lock types were being added without a
corresponding description. Since the lock types (enum values)
are used as indices to the description array, the descriptions
could be shifted depending on the lock type. The solution is to
ensure that every lock type has a correspondent description.
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.
- Header <sys/ttydefaults.h> missing or not usable on QNX and OpenServer 6
include/my_global.h
- Moved down definition of function rint(), as for some platforms (in
this case Netware) 'longlong' is not defined until later in
"my_global.h"
Probe definition file is now a separate file that is copied during
build to the correct location, this enforces dependency requirements
correctly and allows builds to work when using the current or separate
build directories
Took the Xfree implementation (based on the same rewrite as the NDB one)
and added it instead of the current implementation.
Added a macro to make the calls to MD5 more streamlined.
When disk is full, server may waiting for free space while
writing binlog, relay-log or MyISAM tables. The server will
continue after user have freed some space. But the error
message printed was not quite clear about the how often the
error message is printed, and there will be a delay before
the server continue and user freeing space. And caused users
thinking that the server was hanging forever.
This patch fixed the problem by making the error messages
printed more clear. The error message is split into two part,
the first part will only be printed once, and the second part
will be printed very 10 times.
Message first part:
Disk is full writing '<filename>' (Errcode: <errorno>). Waiting
for someone to free space... (Expect up to 60 secs delay for
server to continue after freeing disk space)
Message second part:
Retry in 60 secs, Message reprinted in 600 secs
in load_defaults()
load_defaults(), my_search_option_files() and
my_print_default_files() utilized a global variable
containing a pointer to thread local memory. This could lead
to race conditions when those functions were called with high
concurrency.
Fixed by changing the interface of the said functions to avoid
the necessity for using a global variable.
Since we cannot change load_defaults() prototype for API
compatibility reasons, it was renamed my_load_defaults().
Now load_defaults() is a thread-unsafe wrapper around
a thread-safe version, my_load_defaults().
for bug #15936.
On some platforms fenv.h may #undef the min/max macros
defined in my_global.h.
Fixed by moving the #include directive for fenv.h from
mysqld.cc to my_global.h before definitions for min/max.
Add all HA error numbers and descriptions to perror.
Add reminder to header.
This is already fixed in smarter ways in future codebases, and this
codebase is unlikely to change, since new development is forbidden
here.
Improved data typing of server variables in InnoDB to avoid bugs on
Windows.
Workaround for bug in gcc assembler on 32-bit Mac OS X as well as
on Solaris.
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.
