old versions of bison.

Added semicolons.

Invaldating a subset of a sufficiently large query cache can take a long time.
During this time the server is efficiently frozen and no other operation can
be executed. This patch addresses this problem by setting a time limit on
how long time a dictionary access request can take before giving up on the 
attempt. This patch does not work for query cache invalidations issued by
DROP, ALTER or RENAME TABLE operations.


sql/sql_cache.cc:
  Changed mutex locking to a timed spinn lock. If access to query cache dictionary
  takes "a long time" (currently more than 0.1 seconds) the system fall backs on
  ordinary statement execution.

The problem is that a SELECT on one thread is blocked by INSERT ... ON
DUPLICATE KEY UPDATE on another thread even when low_priority_updates is
activated.

The solution is to possibly downgrade the lock type to the setting of
low_priority_updates if the INSERT cannot be concurrent.


sql/sql_insert.cc:
  Possibly downgrade lock type to the the setting of low_priority_updates if
  if the INSERT cannot be concurrent.

Use double quotes instead of single ones which make the test fail on Windows. This is for bug #30164.


mysql-test/t/mysql.test:
  Use double quotes instead of single ones which make the test fail on Windows.

  
Problem:
  
In cases when a client-side macro appears inside a server-side comment, the add_line() function in mysql.cc discarded all characters until the next delimiter to remove macro arguments from the query string. This resulted in broken queries being sent to the server when the next delimiter character appeared past the comment's boundaries, because the comment closing sequence ('*/') was discarded.
  
Fix:
  
If a client-side macro appears inside a server-side comment, discard all characters in the comment after the macro (that is, until the end of the comment rather than the next delimiter).
This is a minimal fix to allow only simple cases used by the mysqlbinlog utility. Limitations that are worth documenting:
  
- Nested server-side and/or client-side comments are not supported by mysql.cc
- Using client-side macros in multi-line server-side comments is not supported
- All characters after a client-side macro in a server-side comment will be omitted from the query string (and thus, will not be sent to server).

  If a client-side macro appears inside a server-side comment, discard all characters in the comment after the macro.

comments)

Before this fix, the server would accept queries that contained comments,
even when the comments were not properly closed with a '*' '/' marker.

For example,
  select 1 /* + 2 <EOF>
would be accepted as
  select 1 /* + 2 */ <EOF>
and executed as
  select 1

With this fix, the server now rejects queries with unclosed comments
as syntax errors.
Both regular comments ('/' '*') and special comments ('/' '*' '!') must be
closed with '*' '/' to be parsed correctly.

  Unbalanced comments are a syntax error.

This is a performance bug, affecting in particular the bison generated code
for the parser.

Prior to this fix, the grammar used a long chain of reduces to parse an
expression, like:
  bit_expr -> bit_term
  bit_term -> bit_factor
  bit_factor -> value_expr
  value_expr -> term
  term -> factor
etc

This chain of reduces cause the internal state automaton in the generated
parser to execute more state transitions and more reduces, so that the
generated MySQLParse() function would spend a lot of time looping to execute
all the grammar reductions.

With this patch, the grammar has been reorganized so that rules are more
"flat", limiting the depth of reduces needed to parse <expr>.

Tests have been written to enforce that relative priorities and properties
of operators have not changed while changing the grammar.

See the bug report for performance data.

If, after the tables are locked, one of the conditions to read from a
HANDLER table is not met, the handler code wrongly jumps to a error path
that won't unlock the tables.

The user-visible effect is that after a error in a handler read command,
all subsequent handler operations on the same table will hang.

The fix is simply to correct the code to jump to the (same) error path that
unlocks the tables.
