Pyosmium comes with convenient functions for finding the
right state and does not require external files for
rembering the state. Updates can now conveniently
set up by simply running ./utils/update.php --init-updates
and state is kept directly in the import_status table.
This change requires an update in the database schema.
Run the following to update:
ALTER TABLE import_status ADD COLUMN sequence_id integer;
ALTER TABLE import_status ADD COLUMN indexed boolean;
ALTER TABLE import_osmosis_log ADD COLUMN batchseq integer;
Get the version from the database where necessary or simply
probe for existence of features. Fake hstore_to_json when
necessary.
Bumps the minimum required versions fro postgres to 9.1 and
for postgis to 2.0.
Executables (including websites) need to be installed in the
build directory, so that they can find the right settings.php.
settings now defines build and source dir.
use osmosis --read-replication-lag to determine if there are changes before trying to process updates, useful when we are tracking hourly or daily replication updates
set CONST_Replication_Recheck_Interval to 60
skip lag check if CONST_Replication_Update_Interval > 60, for minutelies there's always new diffs to process
use tabs for indent
change sleep for non-minutely updates so that we dont drift tto much or poll excessively
unset $aReplicationLag before each exec attempt
unset $aReplicationLag inside while loop
function changes:
-----------------
Move to ST_PointOnSurface from ST_Centroid in various places to avoid looking up a point outside the polygon
Move to ST_Covers from ST_Contains to include points on admin boundaries
Re-order preference for get_country_code now our data is better. country_osm_grid is now the preffered source.
Fix code to calculate country code in placex_insert, rank_search test was too early
Add extra field to placex 'calculated_country_code' to improve structure of code
Move split_geometery function out of add_location into its own function
Rewrite split_geometery to be more efficient.
Change place_insert to do more updates and less delete/inserts (delete is slow)
Include wikipedia links in details.php ouput
Cleanup no longer used geometry validation (adding overhead)
Include debug statements in function.sql (--DEBUG: ) and add flag to setup.php to turn them on
setup.php:
----------
add flag --disable-token-precalc to speed up debuging
add flag --index-noanalyse to disable analysising DB at rank 4 and 26 (previously removed, but on my local DB it seems to be required)
add flag --enable-diff-updates (modifier to --create-functions) to turn on the code required for diff updates without having to modify functions.sql
add flag --enable-debug-statements (modifier to --create-functions) to turn on debug warning statements
update.php:
-----------
added flag --no-index to import osmosis changes without indexing them
extend the hack to allow import of JOSM generated osm files
country_grid.sql - reference copy of the sql used to generate the country_osm_grid table, needs cleanup
- new config options for postgresql version and
location of osm2pgsql and osmosis binaries
- new option --no-npi for update.php that supresses writing of NPIs in
osmosis update mode
- add more GRANTs for www-data
