This commit removes the WITH_SSL=<custom_location_of_openssl> option,
leaving only -DWITH_SSL=bundled/system.
The rationale behind this removal is as follows:
1. The WITH_SSL=<custom_location_of_openssl> option is obscure
and not widely used.
2. There is no added value in this option compared to using
OPENSSL_ROOT_DIR. In fact, the availability of "helpful" MySQL options
might discourage users from exploring proper CMake options independently.
3. Users may incorrectly assume full MySQL compatibility even with this
option, including undocumented behaviors such as MySQL's preference for static libraries
with WITH_SSL=<custom_location_of_openssl>.
This change simplifies the configuration options and encourages users to
adopt more standardized and documented practices.
MDEV-33621 Unify duplicate code in my_wildcmp_uca_impl() and my_wildcmp_unicode_impl()
This is a refactoring patch, it does not change the behaviour.
The MTR tests are being added only to cover the LIKE predicate better.
(these tests should have been added earlier under terms of MDEV 9711).
This patch does not need its own specific MTR tests.
Moving the duplicate code into a new shared file ctype-wildcmp.inl
and including it from multiple places, to define the following functions:
- my_wildcmp_uca_impl(), in ctype-uca.c
For utf8mb3, utf8mb4, ucs2, utf16, utf32, using cs->cset->mb_wc().
For UCA based collations.
- my_wildcmp_mb2_or_mb4_general_ci_impl(), in ctype-ucs2.c:
For ucs2, utf16, utf32, using cs->cset->mb_wc().
For general_ci-style collations:
- xxx_general_ci
- xxx_general_mysql500_ci
- xxx_general_nopad_ci
- my_wildcmp_mb2_or_mb4_bin_impl(), in ctype-ucs2.c:
For ucs2, utf16, utf32, using cs->cset->mb_wc().
For _bin collations:
- xxx_bin
- xxx_nopad_bin
- my_wildcmp_utf8mb3_general_ci_impl(), in ctype-utf8.c
Optimized for utf8mb3, using my_mb_wc_utf8mb3_quick().
For general_ci-style collations:
- utf8mb3_general_ci
- utf8mb3_general_mysql500_ci
- utf8mb3_general_nopad_ci
- my_wildcmp_utf8mb4_general_ci_impl(), in ctype-utf8.c
Optimized for utf8mb4, using my_mb_wc_utf8mb4_quick().
For general_ci-style collations:
- utf8mb4_general_ci
- utf8mb4_general_nopad_ci
Extra tests for MDEV-30716 Wrong casefolding in xxx_unicode_520_ci for U+0700..U+07FF
New tests display additional information about characters from the BMP range:
- A summary with a COUNT(*) for all distinct combinations of properties
telling how the "=" and the "LIKE" predicates compare characters to their
LOWER() and UPPER() variants.
- A detailed list of trciky characters
for which the "=" and the "LIKE" predicates compare
LOWER(c)/UPPER(c) variants as not equal to just "c".
Tricky characters include:
- Turkish letters: ı - small dotless letter i
- Croatian letters: precombined contractions for Dž, Dz, Lj, Nj
- Units of measurement: Ω,K,Å (Ohm, Kelvin, Angstrom)
These ones look very similar to Greek letter Omega,
Latin letter Kra, Swedish/Finnish letter A with a ring above.
