Started writing detailed error handler of
ALTER TABLE for partitioning.
Philosophical issue, should one always attempt to make recovery
automatic or should one rely on manual means also.
Before the interval expression was considered to be in seconds, now it is
just a number and the type of interval is considered.
- this changeset introduces also fix for bug#16432 (Events: error re interval
misrepresents the facts)
the code of event_timed::set_interval() was refactored anyway so it is meaningful to
fix the bug in the same changeset.
Optimised version of ADD/DROP/REORGANIZE partitions for
non-NDB storage engines.
New syntax to handle REBUILD/OPTIMIZE/ANALYZE/CHECK/REPAIR partitions
Quite a few bug fixes
The patch adds DYNAMIC_ARRAY all_status_vars, which is now the
sole source of status information for SHOW STATUS. Status
variables can be added to and removed from the array dynamically.
SHOW STATUS command uses this array instead of static array
from mysqld.cc
Compatibility with the old, global list of status variables is
preserved in init_server_components(), where this global list is
simply appended to all_status_vars.
which makes it possible to run RENAME TABLE
on old tables when upgrading from 5.0.
TODO: A stored procedure to rename all tables and
databases with old name format into new format,
it will simplify upgrade.
sql_table.cc:
Making old tables seen with "#mysql50#" prefix.
Adding warning into .err log when an old name is found.
sql_show.cc:
Skip non-directories before filename_to_tablename
call, to avoid unnecessary warnings.
strfunc.cc:
Adding "error" argument to strconvert()
mysql_priv.h:
Adding "error" agrument to strconvert()
- Encoding itself, implemented as a charset
"filename". Originally planned to use '.'
as an escape character, but now changed to '@'
for two reasons: "ls" does not return
file names starting with '.' considering them
as a kind of hidden files; some platforms
do not allow several dots in a file name.
- replacing many calls of my_snprintf() and
strnxmov() to the new build_table_filename().
- Adding MY_APPEND_EXT mysys flag, to append
an extention rather that replace it.
- Replacing all numeric constants in fn_format
flag arguments to their mysys definitions, e.g.
MY_UNPACK_FILENAME,
- Predictability in several function/methods:
when a table name can appear with or withot .frm
extension. Some functions/methods were changed
so accept names strictly with .frm, other - strictly
without .frm extensions. Several DBUG_ASSERTs were
added to check whether an extension is passed.
Many files:
table name to file name encoding
mysql_priv.h:
Prototypes for new table name encoding tools.
ctype-utf8.c:
Implementing "filename" charset for
table name to file name encoding.
row0mysql.c:
Fixing table name prefix.
mf_format.c:
Adding MY_APPEND_EXT processing.
Many files:
Fixing tests.
my_sys.h:
Adding new flag to append rather than replace an extension.
m_ctype.h:
Adding "filename" charset definition.
Problem #1: INSERT...SELECT, Version for 5.1.
Extended the unique table check by a check of lock data.
Merge sub-tables cannot be detected by doing name checks only.
