This keeps the names tracable and ensures that all names are searchable
when they differ. Do not keep names when they are exactly the same
to save some space. Linked names are cleaned out before relinking.
The new icu tokenizer is now no longer compatible with the old
legacy tokenizer in terms of data structures. Therefore there
is also no longer a need to refer to the legacy tokenizer in the
name.
Postgresql is very bad at creating statistics for jsonb
columns. The result is that the query planer tends to
use JIT for queries with a where over 'info' even when
there is an index.
The BDD tests cannot make assumptions about the structure of the
word table anymore because it depends on the tokenizer. Use more
abstract descriptions instead that ask for specific kinds of
tokens.
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.
Indexing is now split into three parts: first a preparation step
that collects the necessary information from the database and
returns it to Python. In a second step the data is transformed
within Python as necessary and then returned to the database
through the usual UPDATE which now not only sets the indexed_status
but also other fields. The third step comprises the address
computation which is still done inside the update trigger in
the database.
The second processing step doesn't do anything useful yet.
Drops all calls to PHP utility functions. nominatim cli functions
are used where possible, to stay as close to the final code as
possible with the tests.
By removing the PHP calls, the test code now only uses osm2pgsql and
the database module from the build directory.
Introduces a new class DBRow that encapsulates the comparison
functions. This also is responsible for formatting more informative
assert messages. place and placex steps are unified.
Put the connection to the test database into auto-commit mode
and get rid of the explicit commits. Also use cursors always in
context managers and unify the two implementations that copy
data from the place table.
