unicode: only export internal symbols for the selftests

2021-10-12T14:41:39+00:00

The exported symbols in utf8-norm.c are not needed for normal file system consumers, so move them to conditional _GPL exports just for the selftest. Signed-off-by: Christoph Hellwig Signed-off-by: Gabriel Krisman Bertazi

unicode: Add utf8-data module

2021-10-12T14:41:39+00:00

utf8data.h contains a large database table which is an auto-generated decodification trie for the unicode normalization functions. Allow building it into a separate module. Based on a patch from Shreeya Patel . Signed-off-by: Christoph Hellwig Signed-off-by: Gabriel Krisman Bertazi

unicode: cache the normalization tables in struct unicode_map

2021-10-11T20:02:02+00:00

Instead of repeatedly looking up the version add pointers to the NFD and NFD+CF tables to struct unicode_map, and pass a unicode_map plus index to the functions using the normalization tables. Signed-off-by: Christoph Hellwig Signed-off-by: Gabriel Krisman Bertazi

unicode: move utf8cursor to utf8-selftest.c

2021-10-11T20:01:58+00:00

Only used by the tests, so no need to keep it in the core. Signed-off-by: Christoph Hellwig Signed-off-by: Gabriel Krisman Bertazi

unicode: simplify utf8len

2021-10-11T20:01:54+00:00

Just use the utf8nlen implementation with a (size_t)-1 len argument, similar to utf8_lookup. Also move the function to utf8-selftest.c, as it isn't used anywhere else. Signed-off-by: Christoph Hellwig Signed-off-by: Gabriel Krisman Bertazi

unicode: remove the unused utf8{,n}age{min,max} functions

2021-10-11T20:01:50+00:00

No actually used anywhere. Signed-off-by: Christoph Hellwig Signed-off-by: Gabriel Krisman Bertazi

unicode: pass a UNICODE_AGE() tripple to utf8_load

2021-10-11T20:01:46+00:00

Don't bother with pointless string parsing when the caller can just pass the version in the format that the core expects. Also remove the fallback to the latest version that none of the callers actually uses. Signed-off-by: Christoph Hellwig Signed-off-by: Gabriel Krisman Bertazi

unicode: implement higher level API for string handling

2019-04-25T17:51:22+00:00

This patch integrates the utf8n patches with some higher level API to perform UTF-8 string comparison, normalization and casefolding operations. Implemented is a variation of NFD, and casefold is performed by doing full casefold on top of NFD. These algorithms are based on the core implemented by Olaf Weber from SGI.
