Check for existence of diff fails on Solaris due to unsupported "-v"
Fix is to do this check only on Windows where it was needed

packages, this is now corrected (Bug#42278)

This is not the final merge of that release build, but we need early
access to these tool fixes (use of "awk" in the BDB configuration).

The default "awk" there cannot handle some of the scripts
which are used by BDB for configuration.

The fix:
1) Introduce a variable "AWK" in some of the BDB shell scripts,
2) search "gawk" and give it precedence over "awk"
   when assigning a value to the "AWK" variable,
   fail if neither is found,
3) use that variable when calling an "awk" program with one
   of the critical scripts.

The perfect solution would be to use the "awk" program found
by "configure", but we cannot follow that approach because
BDB's configuration is handled as a special case before the
overall "configure" is run. Because of this,
1) the "configure" result isn't yet available,
2) "configure" will not handle these BDB files.
Searching "gawk" is a (not-so-nice) way out.

Note that all this need not be perfectly portable,
it is needed only when we create a source distribution tarball
from a develkopment tree.

bdb/dist/s_all:
  Search "gawk" if available, give it precedence over "awk",
  fail if neither is found.
bdb/dist/s_include:
  Ensure we use a modern AWK, similar to GNU awk,
  the default awk on Solaris cannot handle BDB's script.
bdb/dist/s_recover:
  Ensure we use a modern AWK, similar to GNU awk,
  the default awk on Solaris cannot handle BDB's script.
bdb/dist/s_rpc:
  Ensure we use a modern AWK, similar to GNU awk,
  the default awk on Solaris cannot handle BDB's script.

Bug #39920: MySQL cannot deal with Leap Second expression in string literal.

Updated MySQL time handling code to react correctly on UTC leap second additions.
MySQL functions that return the OS current time, like e.g. CURDATE(), NOW() etc
will return :59:59 instead of :59:60 or 59:61.
As a result the reader will receive :59:59 for 2 or 3 consecutive seconds
during the leap second.

Bug#34760 Character set autodetection appears to fail
the problem is the same as reported in bug#20835,
so the fix is backport of bug#20835 patch.

When substituting system constant functions with a constant result
the server was not expecting that the function may return NULL.
Fixed by checking for NULL and returning Item_null (in the relevant
collation) if the result of the system constant function was NULL.

Passing dubious "year zero" in non-zero date (not "0000-00-00") could
lead to negative value for year internally, while variable was unsigned.
This led to Really Bad Things further down the line.

  show that very early dates no longer break DATE_FORMAT(..., '%W')
sql-common/my_time.c:
  Allow negative years numbers internally while keeping the interface.
  otherwise if somebody passes year zero for whatever reason, we'll
  get an integer wrap-around that can lead to Really Bad Things further
  down the line. Note that amusingly, calcday_nr() already had signed
  output and calc_weekday() already had signed input, anyway.

Added function to check for diff and return an error message if the utility is not present.
Previously, the way we did this didn't work on Windows, but did work on *Nix systems.

Table could be marked dependent because it is
either 1) an inner table of an outer join, or 2) it is a part of
STRAIGHT_JOIN. In case of STRAIGHT_JOIN table->maybe_null should not
be assigned. The fix is to set st_table::maybe_null to 'true' only
for those tables which are used in outer join.

The problem is that we cannot insert new record into memory table
when table size exceeds max memory table size.
The fix is to use schema_table_store_record() function which
converts memory table into MyISAM in case of table size exceeding.

Note:
There is no test case for this bug, the reason is that
1. The code  that was added already is checked(i.e. works) with existing tests
2. Correct work of schema_table_store_record() is checked with other test cases
   (information_schema tests)
So new code is fully covered with existing test cases.

  make schema_table_store_record() function global

- QUICK_INDEX_MERGE_SELECT deinitializes its rnd_pos() scan when it reaches EOF, but we 
  need to make the deinitialization in QUICK_INDEX_MERGE_SELECT destructor also. This is because
  certain execution strategies can stop scanning without reaching EOF, then then try to do a full
  table scan on this table. Failure to deinitialize caused the full scan to use (already empty) 
  table->sort and produce zero records.

branches/5.0   bug#39483 InnoDB hang on adaptive hash because of out

Under some conditions MySQL calls ::open with search_latch leading
to a deadlock as we try to acquire dict_sys->mutex inside ::open
breaking the latching order. The fix is to release search_latch.
