Yoni Fogel 216aec3fb9 refs #5149 Fix up ydb layer read-only txn optimizations. 
The is_read_only function already took into account children, so we don't need complicated logic.

Look for the error in /home/bradley/mysql/bdbi/usr/var/yobert.err



----
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:

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

make
make install
/home/bradley/usr/bin/mysql_install_db 
/home/bradley/usr/bin/mysqld_safe &
/home/bradley/usr/bin/mysql -u root
~/mysql/bdbi/usr/bin/mysql -u root
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: compiler mysql wiht 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
