      Fix for bug #45143 "All connections hang on concurrent ALTER TABLE". · dfa2acb1
      Dmitry Lenev authored 
      Concurrent execution of statements which require non-table-level
write locks on several instances of the same table (such as
SELECT ... FOR UPDATE which uses same InnoDB table twice or a DML
statement which invokes trigger which tries to update same InnoDB
table directly and through stored function) and statements which
required table-level locks on this table (e.g. LOCK TABLE ... WRITE,
ALTER TABLE, ...) might have resulted in a deadlock.

The problem occured when a thread tried to acquire write lock
(TL_WRITE_ALLOW_WRITE) on the table but had to wait since there was
a pending write lock (TL_WRITE, TL_WRITE_ALLOW_READ) on this table
and we failed to detect that this thread already had another instance
of write lock on it (so in fact we were trying to acquire recursive
lock) because there was also another thread holding write lock on the
table (also TL_WRITE_ALLOW_WRITE). When the latter thread released
its lock neither the first thread nor the thread trying to acquire
TL_WRITE/TL_WRITE_ALLOW_READ were woken up (as table was still write
locked by the first thread) so we ended up with a deadlock.

This patch solves this problem by ensuring that thread which
already has write lock on the table won't wait when it tries
to acquire second write lock on the same table.

      Bug #48317 cannot build innodb as static library. · b1c355b3
      Vladislav Vaintroub authored 
      The problem here is that the latest innodb push contains
both MYSQL_STORAGE_ENGINE(INNOBASE) and MYSQL_STORAGE_ENGINE(INNOBASE)
in the same CMakeLists.txt, to make the resulting library
ha_innodb.dll, instead of ha_innobase.dll.

Using multiple MYSQL_STORAGE_ENGINE within the same  CMakeLists.txt
conflicts with the fix for the bug Bug #47795 "CMake, storage engine
name different from directory name". Top-level CMakeLists.txt now 
parses storage engine's  CMakeLists.txt to extract engines name from 
MYSQL_STORAGE_ENGINE().

For innodb, it concludes that there is not storage engine named
INNOBASE, hence WITH_INNOBASE_STORAGE_ENGINE has no effect.

The fix is to use SET_TARGET_PROPERTIES(... PROPERTIES OUTPUT_NAME ...),
instead of renaming the engine to have plugins named ha_innodb.dll.
