v2: Add a note that top_level_domains_lists aren not applied w/o restart
v3: Remove ExtractFirstSignificantSubdomain{Default,Custom}Lookup.h headers
v4: TLDListsHolder: remove FIXME for dense_hash_map (this is not significant)
- Update after IFunction interfaces changes
- move type checks into FunctionCountMatches::getReturnTypeImpl()
- Use StringRef over String
- Separate out logic for counting sub matches into separate helper
- Do not copy other regular expression matches, only the first
- Add some comments
- Set is_no_capture, to avoid check for number of subpatterns
- Add countMatchesCaseInsensitive()
- Reguster functions in case-sensitive manner, since this is not SQL
standard
Function to count number of substring occurrences in the string:
- in case of needle is multi char - counts non-intersecting substrings
- the code is based on position helpers.
The following new functions is available:
- countSubstrings()
- countSubstringsCaseInsensitive()
- countSubstringsCaseInsensitiveUTF8()
v0: substringCount()
v2:
- add substringCountCaseInsensitiveUTF8
- improve tests
- fix coding style issues
- fix multichar needle
v3: rename to countSubstrings (by analogy with countEqual())
Functions to encrypt/decrypt any input data with OpenSSL's ciphers
with custom key, iv, and add (-gcm mode only).
_mysql versions are 100% compatitable with corresponding MySQL functions
Supported modes depend on OpenSSL version, but generally are:
aes-{128,192,56}-{ecb,cbc,cfb1,cfb8,cfb128,ofb,gcm}
Please note that in a -gcm mode a 16-byte tag is appended to the ciphertext
on encryption and is expected to be found at the end of ciphertext on decryption.
Added tests that verify compatibility with MySQL functions,
and test vectors for GCM mode from OpenSSL.
Added masking rules for aes_X funtions
Rules are installed by default to config.d/query_masking_rules.xml
