Description Magnus Enger 2016-09-07 11:54:29 UTC
koha-dump-defaults runs mysqldump and then pipes the result to sed, to replace every occurence of the site name with the placeholder __KOHASITE__

  mysqldump --databases --host="$mysqlhost" --user="$mysqluser" \
    --password="$mysqlpass" "$mysqldb" |
    sed "s/$name/__KOHASITE__/g"

I had used the silly name "data" as the site name for my "template instance", and this resulted in innocent things like 

  -- Dumping __KOHASITE__ for table `zebraqueue`

and bad things like 

  'Edit catalog (Modify bibliographic/holdings __KOHASITE__)'

or this, in biblioitems.marcxml:

  <__KOHASITE__field>

All told there were 7235 occurences of __KOHASITE__ in my rather small SQL file. 

As suggested by drojf on IRC, I *think* this would be fixed if we replaced "koha_$name" __INSTANCENAME__, instead of just $name.

That should of course be __KOHASITE__, not __INSTANCENAME__.
Comment 2 Magnus Enger 2016-09-07 12:15:49 UTC
...and we would need to change line 744 of koha-create accordingly:

        sed "s/__KOHASITE__/$name/g" |

Apologies for being pedantic, but may I suggest a small change to the bug title?
'koha-create-defaults' is not a valid command. In order to find this bug in
future BZ/git searches for 'koha-create' or 'koha-dump-defaults' I think the
title should be:

"Make koha-create and koha-dump-defaults less greedy"

Bug 17265 - Make koha-create-defaults less greedy

koha-create-defaults substitutes the instance name with the placeholder
__KOHASITE__ in the SQL file that it creates. If the instance name is
something common, like "data", this means that way too many substitutions
will be made, and when koha-create uses the SQL file as a template, broken
data can be the result.

The solution in this patch was suggested by drojf on IRC.

To test:
- Create an instance called "data"
- Run "sudo koha-dump-defaults data > test.sql"
- Take a look at test.sql and verify there are way too many occurences
  of __KOHASITE__, like "-- Dumping __KOHASITE__ for table `accountlines`"
- Apply the patch
- Copy the resulting koha-create and koha-dump-defaults to somewhere
  running off the packages
- Run "sudo koha-dump-defaults data > test.sql" again and verify there
  are only 4 occurrences of __KOHASITE__, in places that make sense
- Create an instance with something like:
  $ gzip test.sql
  $ sudo koha-create --create-db --defaultsql test.sql.gz test17265
- Verify that you have a working Koha install

Works as expected.
