----
This links right:
LD_LIBRARY_PATH=/home/bradley/mysql/bdbi/usr/lib/mysql/ ldd sql/mysqld
----
This works,
LD_LIBRARY_PATH=/home/bradley/mysql/bdbi/usr/lib/mysql/ /home/bradley/mysql/bdbi/usr//bin/mysqld
producing the following in the log
061208 16:11:35 InnoDB: Started; log sequence number 0 43655
ydb.c:78 db_env_create flags=0
----
the LD_RUN_PATH thing above works.
--- on laptop I did this instead:
cd ~/mysql/mysql-5.0.27/
export LD_RUN_PATH=/home/bradley/yobiduck/ydb/src
./configure --with-berkeley-db-includes=/home/bradley/yobiduck/ydb/include --with-berkeley-db --with-berkeley-db-libs=/home/bradley/yobiduck/src --prefix=/home/bradley/usr

mysql> show databases;
mysql> create database yobitest;
mysql> use yobitest;
mysql> create table t1 (i int) engine=bdb;
Look for the error in ~/usr/var/localhost.localdomain.err
---
To clean up after a total screwup:
rm -rf ~/usr/var/
Didn't manage to clean it up very well.
---
Goal: compile mysql with debugging
export LD_RUN_PATH=/home/bradley/yobiduck/ydb/src
./configure CFLAGS="-g -O2" --with-berkeley-db-includes=/home/bradley/yobiduck/ydb/include --with-berkeley-db --with-berkeley-db-libs=/home/bradley/yobiduck/src --prefix=/home/bradley/usr
If you want to debug, you might need to start mysqld without using mysqld_safe.
Here is one way to do it:
gdb ~/usr/libexec/mysqld
(gdb) run --basedir=/home/bradley/usr --datadir=/home/bradley/usr/var --pid-file=/home/bradley/usr/var/localhost.localdomain.pid --skip-external-locking
That was screwed up (the configure args were wrong.) Try again:
---
export LD_RUN_PATH=/home/bradley/yobiduck/ydb/src
./configure CXXFLAGS="-g -O2" CFLAGS="-g -O2" --with-berkeley-db-includes=/home/bradley/yobiduck/ydb/include --with-berkeley-db --with-berkeley-db-libs=/home/bradley/yobiduck/ydb/src --prefix=/home/bradley/usr
gdb ~/usr/libexec/mysqld
(gdb) run --basedir=/home/bradley/usr --datadir=/home/bradley/usr/var --pid-file=/home/bradley/usr/var/localhost.localdomain.pid --skip-external-locking
and
~/usr/bin/mysql -u root
Note: Had to change mysql to declare berkeley_cmp_hidden_key and berkeley_cmp_packed_key to be extern, not static.
----
To start the mysql clean:
rm -r /home/bradley/usr/var/
/home/bradley/usr/bin/mysql_install_db
then run mysqld and mysql do
$ ~/usr/bin/mysql -u root
mysql> create database yobitest;
mysql> use yobitest;
mysql> create table t1 (i int) engine=bdb;
mysql> insert t1 values (3);
mysql> quit
~/usr/bin/mysqladmin -u root shutdown
Then create the trace1 from ydbtrace.c
(copy the output onto traces/trace1.c
cd traces
make
rm ~/usr/var/log.0000000001
rm ~/usr/var/yobitest/t1.db
./runtrace1

This directory provides a wrapper using the ydb db.h header file but
it calls the bdb internals. To get this to work requires a little
magic, since both BDB and YDB use the same type names.
BDB helps with a ./configure option (--with-uniquename) that makes it
so that all the link-time symbols have different names. But the type
names and enums collide. Hence we cannot include both the
../include/db.h and the BDB db.h.
To fix that we have a header ydb-uniq.h, which uses completely
different names for everything in the ydb interface. But those names
are compatible with the standard names: That is all the structs have
the same layout.
Thus we have the following three headers
bdb_db.h which defines things like db_env_create_4001(DBENV **, ...)
ydb_db.h which defines things like db_env_create(DBENV **, ...) (but the DBENV is a different type from BDB's)
bdbw.h which defines things like db_env_create_ydb(DBENV_ydb **, ...)
bdbw.h can be included with bdb_db.h or ydb_db.h
bdb_db.h and ydb_db.h cannot both be included in the same file.
An application, such as mysql, includes db.h from ../include
That is the ydb header file.
