When ALTER TABLE ... ENGINE= is called the following happens:
1. A temporary table is created in the new engine with the real table
name but a temporary file name supplied
2. A bulk insert is started from old to new table
3. The old table is dropped
4. The new table is renamed
For #1 we use the real table name instead of the temporary file name
(otherwise step #2 breaks), we were therefore trying to skip #4.
This broke regular RENAME TABLE commands.
With this patch we detect if the rename is for a temporary to real table
and skip it. Since this is the only instance where we support temporary
tables.
This patch also fixes issues with extracting table names from file
names and some other irrelevant stuff.
Longer term if we want to support temporary tables we need to store the
provided filename in our metadata since it could be different from table
name.
processing that was broken after vtable had been removed.
Before this patch IN-INTO-EXISTS rewrite doesn't add equi-JOIN predicate when
IN+subquery was in a nested subquery.
log_bin is missing from columnstore.cnf. This causes a search for the
master log file to fail and replication doesn't apply.
This patch adds a commented out log_bin which is enabled as needed.
It also fixes an error message.
this is executed when ha_columnstore is loaded, at dlopen time
before any initialization code is run and crashes any dlopen
attemps.
Crashes - because a missing config file is a crashing offence,
but it's an issue for another day
Changed the row-based repl detection mechanism so stmt-based repl works
again, however, the detection mechanism is still wrong somehow. What it
should be is currently unknown.
We were auto-assigned a DB type which could cause issues during major
upgrades. Setting to autoassign gives us a DB type of 0 which solves
these issues.
Direct update/delete executed doUpdateDelete as well as the regular
execution route for doUpdateDelete.
This patch only executes doUpdateDelete the first time and direct
update/delete collects the counts.
In 1.4.1 and below UDFs were stored in libcalmysql.so. These have been
move to ha_columnstore.so. Unfortunately the install script ignores the
previous entries. This patch removes any left over entries before adding
the new ones.
Rename packages to MariaDB-columnstore-engine, MariaDB-columnstore-libs
and MariaDB-columnstore-platform.
Also add the "columnstore-" prefix the the components so that MariaDB's
packaging system understands then and add a line to include them in
MariaDB's packaging.
