mariadb/storage/maria/maria_chk.c
Monty dbac2039e8 Fixed some errors & warnings found by clang 
- pcretest.c could use macro with side effect
- maria_chk could access freed memory
- Initialized some variables that could be accessed uninitalized
- Fixed compiler warning in my_atomic-t.c

table was updated, update also the timestamp for when\n\

Recover (repair)/ options (When using '--recover' or '--safe-recover'):\n\
-B, --backup Make a backup of the .MAD file as 'filename-time.BAK'.\n\
--correct-checksum Correct checksum information for table.\n\
-D, --data-file-length=# Max length of data file (when recreating data\n\
file when it's full).\n\
--create-missing-keys\n\
Create missing keys. This assumes that the data\n\
file is correct and that the the number of rows stored\n\
in the index file is correct. Enables --quick.\n\
-e, --extend-check Try to recover every possible row from the data file\n\
Normally this will also find a lot of garbage rows;\n\
Don't use this option if you are not totally desperate.\n\
-f, --force Overwrite old temporary files. Add another --force to\n\
avoid 'sort_buffer_size is too small' errors.\n\
In this case we will attempt to do the repair with the\n\
given sort_buffer_size and dynamically allocate\n\
as many management buffers as needed.\n\
-k, --keys-used=# Tell Aria to update only some specific keys. # is a\n\
bit mask of which keys to use. This can be used to\n\
get faster inserts.\n\
--max-record-length=#\n\
Skip rows bigger than this if aria_chk can't allocate\n\
memory to hold it.\n\
-r, --recover Can fix almost anything except unique keys that aren't\n\
unique.\n\
-n, --sort-recover Forces recovering with sorting even if the temporary\n\
file would be very big.\n\
-p, --parallel-recover\n\
Uses the same technique as '-r' and '-n', but creates\n\
all the keys in parallel, in different threads.");
puts("\
-o, --safe-recover Uses old recovery method; Slower than '-r' but can\n \
handle a couple of cases where '-r' reports that it\n\
can't fix the data file.\n\
--transaction-log Log repair command to transaction log. This is needed\n\
if one wants to use the aria_read_log to repeat the \n\
repair\n\
--character-sets-dir=...\n\
Directory where character sets are.\n\
--set-collation=name\n\
Change the collation used by the index.\n\
-q, --quick Faster repair by not modifying the data file.\n\
One can give a second '-q' to force aria_chk to\n\
modify the original datafile in case of duplicate keys.\n\
NOTE: Tables where the data file is currupted can't be\n\
fixed with this option.\n\
-u, --unpack Unpack file packed with ariapack.\n\
");
puts("Other actions:\n\
-a, --analyze Analyze distribution of keys. Will make some joins in\n\
MariaDB faster. You can check the calculated distribution\n\
by using '--description --verbose table_name'.\n\
--stats_method=name Specifies how index statistics collection code should\n\
treat NULLs. Possible values of name are \"nulls_unequal\"\n\
(default for 4.1/5.0), \"nulls_equal\" (emulate 4.0), and \n\
\"nulls_ignored\".\n\
-d, --description Prints some information about table.\n\
-A, --set-auto-increment[=value]\n\
Force auto_increment to start at this or higher value\n\
If no value is given, then sets the next auto_increment\n\
value to the highest used value for the auto key + 1.\n\
-S, --sort-index Sort index blocks. This speeds up 'read-next' in\n\
applications.\n\
-R, --sort-records=#\n\
Sort records according to an index. This makes your\n\
data much more localized and may speed up things\n\
(It may be VERY slow to do a sort the first time!).\n\
-b, --block-search=#\n\
Find a record, a block at given offset belongs to.\n\
-z, --zerofill Fill empty space in data and index files with zeroes.\n\
This makes the data file movable between different \n\
servers.\n\
--zerofill-keep-lsn Like --zerofill but does not zero out LSN of\n\
data/index pages.");
