I am playing with switching branches in my local qserv.

It is actually quite a process! Here is what I found

so far:

# I won't have access to the PIDs for already

# running services, so better to stop them now.

# That is because things are run from a place that

# looks like:

# ~/stack/Linux64/qserv/master-ga7082f1e02/,

# and we will switch to something like:

# ~/stack/Linux64/qserv/tickets.DM-630-gb26efd78da

qserv-stop.sh

# switch branch

cd ~/repo/qserv

git checkout tickets/DM-630

# build, install

eupspkg -er build

eupspkg -er install

# this is only needed if it is the very first time

# I work with a given version of the branch

eupspkg -er decl

setup qserv <the new version>

# this basically wipes out everything: zookeeper data, mysql data...

# but if I don't do that, I won't have scripts from admin/bin

# for starting/stopping qserv, so I can't skip it. This really

# needs to be fixed...

cd $QSERV_DIR/admin

scons

# if I want to run integration tests, it looks like this is needed too:

setup qserv_testdata

cd $QSERV_DIR/admin

scons client

# and then I need to start services

qserv-start.sh

then qserv-testdata.py should work

This is quite complex and error prone and easy to get wrong.

Could we possibly simplify it?
