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.
Added --slave option if you are trying to syncronize around one server using the lock-directory option plus NFS.
Added options to allow you to run several concurrency runs in one call. aka --concurrency="1, 8, 64, 128"
Time collection is now done in a finer grain manner, and is linked to the sync call (doesn't count the cost of the blocked processes that are setup to run).
When InnoDB compares varchar field in ucs2 with given key using bin collation,
it calls my_strnncollsp_ucs2_bin() to perform comparison.
Because field length was lesser than length of key field should be padded
with trailing spaces in order to get correct result.
Because my_strnncollsp_ucs2_bin() was calling my_strnncollp_ucs2_bin(), which
doesn't pads field, wrong comparison result was returned. This results in
wrong result set.
my_strnncollsp_ucs2_bin() now compares fields like my_strnncollsp_ucs2 do,
but using binary collation.
