The table generation script would incorrectly complain in the recomposition sorting when matching code points. This would not have caused the generation of an incorrect table. Note that this condition is not reachable yet, but could have been reached with future updates. pg_bswap.h does not need to be included in the frontend.x Author: John Naylor Discussion: https://postgr.es/m/CAFBsxsGWmExpvv=61vtDKCs7+kBbhkwBDL2Ph9CacziFKnV_yw@mail.gmail.com
This directory contains tools to generate the tables in
src/include/common/unicode_norm.h, used for Unicode normalization. The
generated .h file is included in the source tree, so these are normally not
needed to build PostgreSQL, only if you need to re-generate the .h file
from the Unicode data files for some reason, e.g. to update to a new version
of Unicode.
Generating unicode_norm_table.h
-------------------------------
Run
make update-unicode
from the top level of the source tree and commit the result.
Tests
-----
The Unicode consortium publishes a comprehensive test suite for the
normalization algorithm, in a file called NormalizationTest.txt. This
directory also contains a perl script and some C code, to run our
normalization code with all the test strings in NormalizationTest.txt.
To download NormalizationTest.txt and run the tests:
make normalization-check
This is also run as part of the update-unicode target.
