Sqlparse

----------------------------

Notable Changes

* Drop support for Python 3.5, 3.6, and 3.7.
* Python 3.12 is now supported (pr725, by hugovk).
* IMPORTANT: Fixes a potential denial of service attack (DOS) due to recursion
error for deeply nested statements. Instead of recursion error a generic
SQLParseError is raised. See the security advisory for details:
https://github.com/andialbrecht/sqlparse/security/advisories/GHSA-2m57-hf25-phgg
The vulnerability was discovered by uriyay-jfrog. Thanks for reporting!

Enhancements:

* Splitting statements now allows to remove the semicolon at the end.
Some database backends love statements without semicolon (issue742).
* Support TypedLiterals in get_parameters (pr649, by Khrol).
* Improve splitting of Transact SQL when using GO keyword (issue762).
* Support for some JSON operators (issue682).
* Improve formatting of statements containing JSON operators (issue542).
* Support for BigQuery and Snowflake keywords (pr699, by griffatrasgo).
* Support parsing of OVER clause (issue701, pr768 by r33s3n6).

Bug Fixes

* Ignore dunder attributes when creating Tokens (issue672).
* Allow operators to precede dollar-quoted strings (issue763).
* Fix parsing of nested order clauses (issue745, pr746 by john-bodley).
* Thread-safe initialization of Lexer class (issue730).
* Classify TRUNCATE as DDL and GRANT/REVOKE as DCL keywords (based on pr719
by josuc1, thanks for bringing this up!).
* Fix parsing of PRIMARY KEY (issue740).

Other

* Optimize performance of matching function (pr799, by admachainz).

----------------------------

Notable Changes

* IMPORTANT: This release fixes a security vulnerability in the
parser where a regular expression vulnerable to ReDOS (Regular
Expression Denial of Service) was used. See the security advisory
for details: https://github.com/andialbrecht/sqlparse/security/advisories/GHSA-rrm6-wvj7-cwh2
The vulnerability was discovered by erik-krogh from GitHub
Security Lab (GHSL). Thanks for reporting!

Bug Fixes

* Revert a change from 0.4.0 that changed IN to be a comparison (issue694).
The primary expectation is that IN is treated as a keyword and not as a
comparison operator. That also follows the definition of reserved keywords
for the major SQL syntax definitions.
* Fix regular expressions for string parsing.

Other

* sqlparse now uses pyproject.toml instead of setup.cfg (issue685).

----------------------------

Enhancements

* Add support for DIV operator (pr664, by chezou).
* Add support for additional SPARK keywords (pr643, by mrmasterplan).
* Avoid tokens copy (pr622, by living180).
* Add REGEXP as a comparision (pr647, by PeterSandwich).
* Add DISTINCTROW keyword for MS Access (issue677).
* Improve parsing of CREATE TABLE AS SELECT (pr662, by chezou).

Bug Fixes

* Fix spelling of INDICATOR keyword (pr653, by ptld).
* Fix formatting error in EXTRACT function (issue562, issue670, pr676, by ecederstrand).
* Fix bad parsing of create table statements that use lower case (issue217, pr642, by mrmasterplan).
* Handle backtick as valid quote char (issue628, pr629, by codenamelxl).
* Allow any unicode character as valid identifier name (issue641).

Other

* Update github actions to test on Python 3.10 as well (pr661, by cclaus).

----------------------------

Notable Changes

* IMPORTANT: This release fixes a security vulnerability in the
strip comments filter. In this filter a regular expression that was
vulnerable to ReDOS (Regular Expression Denial of Service) was
used. See the security advisory for details: https://github.com/andialbrecht/sqlparse/security/advisories/GHSA-p5w8-wqhj-9hhf
The vulnerability was discovered by erik-krogh and yoff from
GitHub Security Lab (GHSL). Thanks for reporting!

Enhancements

* Add ELSIF as keyword (issue584).
* Add CONFLICT and ON_ERROR_STOP keywords (pr595, by j-martin).

Bug Fixes

* Fix parsing of backticks (issue588).
* Fix parsing of scientific number (issue399).

----------------------------

Bug Fixes

* Just removed a debug print statement, sorry...

----------------------------

Notable Changes

* Remove support for end-of-life Python 2.7 and 3.4. Python 3.5+ is now
required.
* Remaining strings that only consist of whitespaces are not treated as
statements anymore. Code that ignored the last element from
sqlparse.split() should be updated accordingly since that function
now doesn't return an empty string as the last element in some
cases (issue496).

Enhancements

* Add WINDOW keyword (pr579 by ali-tny).
* Add RLIKE keyword (pr582 by wjones1).

Bug Fixes

* Improved parsing of IN(...) statements (issue566, pr567 by hurcy).
* Preserve line breaks when removing comments (issue484).
* Fix parsing error when using square bracket notation (issue583).
* Fix splitting when using DECLARE ... HANDLER (issue581).
* Fix splitting of statements using CASE ... WHEN (issue580).
* Improve formatting of type casts in parentheses.
* Stabilize formatting of invalid SQL statements.
