2 Setup the database:
3 $ createdb liquid_feedback
4 $ psql -v ON_ERROR_STOP=1 -f core.sql liquid_feedback
6 Optionally insert demo data:
7 $ psql -v ON_ERROR_STOP=1 -f demo.sql liquid_feedback
9 Compile lf_update binary:
10 $ make
12 Ensure that "lf_update dbname=liquid_feedback",
13 "lf_update_issue_order dbname=liquid_feedback", and
14 "lf_update_suggestion_order dbname=liquid_feedback" are called
15 regularly! It is required to run these commands regularly
16 (i.e. every 5 minutes via cron) to update cached supporter counts,
17 to change the state of issues when neccessary, to calculate the
18 result of votings, etc. If you wish, copy the created lf_update
19 and lf_update_suggestion_order files to /usr/local/bin or a
20 similar directory.
22 It is possible to run these two commands in parallel, if a setup
23 requires splitting the load to multiple processor cores. In other
24 cases it is recommended to run "lf_update" first, and then
25 "lf_update_issue_order" and "lf_update_suggestion_order".
27 On successful run, these commands will not produce any output
28 and exit with code 0. The commands "lf_update_issue_order" and
29 "lf_update_suggestion_order" may be called with a first argument
30 of "-v" to print log output.
32 NOTE: When writing to the database, some INSERTs must be executed
33 within the same transaction, e.g. issues can't exist without
34 an initiative and vice versa.
36 To create an export file, which is containing all but private data,
37 you may use the lf_export shell-script:
38 $ lf_export liquid_feedback export.sql.gz
40 Refer to source code of function "delete_private_data"() to see,
41 which data gets deleted. If you need a different behaviour, please
42 copy the function and modify the lf_export shell script accordingly.
44 To uninstall the software, delete the lf_update binary
45 and drop the database by entering the following command:
46 $ dropdb liquid_feedback
48 Updating is done using the update scripts in the update/ directory.
49 Do not forget to make backups, before installing any updates.
50 After updating it is recommended to recreate the schema as follows
51 (assuming the database superuser is named "postgres"):
52 $ pg_dump --disable-triggers --data-only DATABASE_NAME > tmp.sql
53 $ dropdb DATABASE_NAME
54 $ createdb DATABASE_NAME
55 $ psql -v ON_ERROR_STOP=1 -f core.sql DATABASE_NAME
56 $ su postgres # (execute following command as database superuser)
57 $ psql -v ON_ERROR_STOP=1 -f tmp.sql DATABASE_NAME
58 $ exit # leave "su" command
59 $ rm tmp.sql
