REPAIR of merge table
Bug #56422 CHECK TABLE run when the table is locked reports
corruption along with timeout
The crash happened if a table maintenance statement (ANALYZE TABLE,
REPAIR TABLE, etc.) was executed on a MERGE table and opening and
locking a child table failed. This could for example happen if a child
table did not exist or if a lock timeout happened while waiting for
a conflicting metadata lock to disappear.
Since opening and locking the MERGE table and its children failed,
the tables would be closed and the metadata locks released.
However, TABLE_LIST::table for the MERGE table would still be set,
with its value invalid since the tables had been closed.
This caused the table maintenance statement to try to continue
and upgrade the metadata lock on the MERGE table. But since the lock
already had been released, this caused a segfault.
This patch fixes the problem by setting TABLE_LIST::table to NULL
if open_and_lock_tables() fails. This prevents maintenance
statements from continuing and trying to upgrade the metadata lock.
The patch includes a 5.5 version of the fix for
Bug #46339 crash on REPAIR TABLE merge table USE_FRM.
This bug caused REPAIR TABLE ... USE_FRM to give an assert
when used on merge tables.
The patch also enables the CHECK TABLE statement for log tables.
Before, CHECK TABLE for log tables gave ER_CANT_LOCK_LOG_TABLE,
yet still counted the statement as successfully executed.
With the changes to table maintenance statement error handling
in this patch, CHECK TABLE would no longer be considered as
successful in this case. This would have caused upgrade scripts
to mistakenly think that the general and slow logs are corrupted
and have to be repaired. Enabling CHECK TABLES for log tables
prevents this from happening.
Finally, the patch changes the error message from "Corrupt" to
"Operation failed" for a number of issues not related to table
corruption. For example "Lock wait timeout exceeded" and
"Deadlock found trying to get lock".
Test cases added to merge.test and check.test.
table .frm file
Problem:
========
Myisampack --join did not create the destination table .frm file.
The user had to copy one of the source table .frm file as destination .frm
file for mysql server to recognize. This is just 'user-friendliness' issue.
How it was solved
=================
After successful join and compression we copy the frm file from the first
source table.
Functionality added
===================
myisampack --join=/path/t3 /path/t1 /path/t2 creates
/path/t3.frm (which is bascially copied from first table's frm /path/t1)
Tests
=====
Modified myisampack.test to test two scenario's
1. Positive myisampack --join test
In this case after the join operation is done,we test if the destination
table is accessible from the server
2. Positive myisampack --join test with an existing .frm file.
We test the above case with an existing .frm file for the destination
table. It should return success even in this case.
3. Positive myisampack --join test with no .frm file for source tables
We test the join operation with no .frm files for source tables. It should
complete the join operation without any warnings and error messages
4. Negative myisampack --join test
We test myisampack --join with existing .MYI,.MDI,.frm files for the
destination table. It should fail with exit status 2 in this case.
The test started failing following the push for BUG#41541.
Some of the algorithms access bytes beyond the input data
and this can affect up to one byte less than "word size"
which is BITS_SAVED / 8.
Fixed by adding (BITS_SAVED / 8) -1 bytes to buffer size
(i.e. Memory Segment #2) to avoid accessing un-allocated data.
myisam/mi_packrec.c:
Fixed _mi_read_pack_info() method to allocate (BITS_SAVED/8) - 1
bytes to the Memory Segment #2

mysql-test/t/myisampack.test:
Testcase for BUG#43973
After the table is compressed by the myisampack utility,
opening the table by the server produces valgrind warnings.
This happens because when we try to read a record into the buffer
we alway assume that the remaining buffer to read is always equal
to word size(4 or 8 or 2 bytes) we read. Sometimes we have
remaining buffer size less than word size and trying to read the
entire word size will end up in valgrind errors.
Fixed by reading byte by byte when we detect the remaining buffer
size is less than the word size.
myisam/mi_packrec.c:
Fixed fill_buffer() to read byte by byte when the remaining
buffer size is less than word size.

reset diagnostics area state after error message is sent
With certain data sets (when compressed record length gets bigger than
uncompressed) myisamchk --unpack may corrupt data file.
Fixed that record length was wrongly restored from compressed table.
myisam/mi_check.c:
With compressed tables compressed record length may be bigger than
pack_reclength, thus we may allocate insufficient memory for record
buffer.
Let single function allocate record buffer, performing needed record
length calculations.
Still, it is not doable with parallel repair, as it allocates needed
record buffers at once. For parellel repair added better record length
calculation.
myisam/mi_open.c:
When calculating record buffer size, take into account that compressed
record length may be bigger than uncompressed.
myisam/mi_packrec.c:
With certain data set share->max_pack_length (compressed record length)
may be bigger than share->base.pack_reclength (packed record length).
set_if_bigger(pack_reclength, max_pack_length) in this case causes
myisamchk --unpack to write extra garbage, whereas pack_reclength
remains the same in new index file. As a result we get unreadable
table.
myisam/myisamchk.c:
With compressed tables compressed record length may be bigger than
pack_reclength, thus we may allocate insufficient memory for record
buffer.
Let single function allocate record buffer, performing needed record
length calculations.
