The Python code now takes care of reading postcodes from placex,
enhancing them with potentially existing external postcodes and
updating location_postcodes accordingly. The initial setup and
updates use exactly the same function.
External postcode handling has been generalized. External postcodes
for any country are now accepted. The format of the external postcode
file has changed. We now expect CSV, potentially gzipped. The
postcodes are no longer saved in the database.
The ICU library only offers transliterations for a limited set of
script. Add transliterations for missing scripts from the PostgreSQL
module. These means that the same selection of scripts is supported
as with the old module.
The tokenizer to be used can be choosen with -DTOKENIZER.
Adapt all tests, so that they work with legacy_icu tokenizer.
Move lookup in word table to a function in the tokenizer.
Special phrases are temporarily imported from the wiki until
we have an implementation that can import from file. TIGER
tests do not work yet.
The indexer now fetches any extra data besides the place_id
asynchronously while processing the places from the last batch.
This also means that more places are now fetched at once.
This adds an installation step for PHP code for the tokenizer. The
PHP code is split in two parts. The updateable code is found in
lib-php. The tokenizer installs an additional script in the
project directory which then includes the code from lib-php and
defines all settings that are static to the database. The website
code then always includes the PHP from the project directory.
The BDD tests still use the old-style amenity creation scripts
because we don't have simple means to import a hand-crafted
test file of special phrases right now.
Normalization and token computation are now done in the tokenizer.
The tokenizer keeps a cache to the hundred most used house numbers
to keep the numbers of calls to the database low.
The name analyzer is the actual work horse of the tokenizer. It
is instantiated on a thread-base and provides all functions for
analysing names and queries.
