Don't do anything if a downloaded diff is empty after all
(may be happening when an empty diff was published upstream).
Correctly compute the waiting interval before checking for new
data. As the interval is now computed based on the date of the
newest object in the database, the configured intervals need
to be adjusted slightly to take into account the time it takes
for the server to publish a diff.
Compare the normalized terms imported with the special
terms script with the normalized version of the query string.
Disregard them if they cannot be found. This avoids a significant
number of mismatches due to transliteration issues.
The match will only be done when a normalized word has been set
making this change backwards compatible with older databases.
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;
Search results can become odd without the country search
terms, so make their inclusion a mandatory part of the
setup.
Also adds a new configuration variable to restrict the
languages taken into account by Nominatim.
Utils scripts must be run from the build directory to make sure
we get the right paths. Rename the settings file in source and
replace the original one with an error, so that scripts
fail with an understandable error message when run from the
source directory.
