bpo-15999: Accept arbitrary values for boolean parameters. (#15609)
builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.

gh-99537: Use Py_SETREF() function in C code (#99656)
Fix potential race condition in code patterns:

* Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);"
* Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);"
* Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);"

Other changes:

* Replace "old = var; var = new; Py_DECREF(var)"
  with "Py_SETREF(var, new);"
* Replace "old = var; var = new; Py_XDECREF(var)"
  with "Py_XSETREF(var, new);"
* And remove the "old" variable.

gh-90928: Improve static initialization of keywords tuple in AC (#95907) 2022-08-13 12:09:40 +02:00
Eric Snow 6f6a4e6cc5
gh-90928: Statically Initialize the Keywords Tuple in Clinic-Generated Code (gh-95860)
We only statically initialize for core code and builtin modules.  Extension modules still create
the tuple at runtime.  We'll solve that part of interpreter isolation separately.

This change includes generated code. The non-generated changes are in:

* Tools/clinic/clinic.py
* Python/getargs.c
* Include/cpython/modsupport.h
* Makefile.pre.in (re-generate global strings after running clinic)
* very minor tweaks to Modules/_codecsmodule.c and Python/Python-tokenize.c

All other changes are generated code (clinic, global strings).

gh-95132: Correctly relay *args and **kwds from sqlite3.connect to factory (#95146)
This PR partially reverts gh-24421 (PR) and fixes the remaining concerns
given in gh-93044 (issue):

- keyword arguments are passed as positional arguments to factory()
- if an argument is not passed to sqlite3.connect(), its default value
  is passed to factory()

gh-79579: Improve DML query detection in sqlite3 (#93623)
The fix involves using pysqlite_check_remaining_sql(), not only to check
for multiple statements, but now also to strip leading comments and
whitespace from SQL statements, so we can improve DML query detection.

pysqlite_check_remaining_sql() is renamed lstrip_sql(), to more
accurately reflect its function, and hardened to handle more SQL comment
corner cases.

It combines PyImport_ImportModule() and PyObject_GetAttrString()
and saves 4-6 lines of code on every use.

gh-89022: Improve sqlite3 exceptions related to binding params and API misuse (#91572)
* Map SQLITE_MISUSE to sqlite3.InterfaceError

SQLITE_MISUSE implies misuse of the SQLite C API, which, if it happens,
is _not_ a user error; it is an sqlite3 extension module error.

* Raise better errors when binding parameters fail.

Instead of always raising InterfaceError, guessing what went wrong,
raise accurate exceptions with more accurate error messages.

* Improve exception compliance with PEP 249
* Raise InterfaceError instead of ProgrammingError for SQLITE_MISUSE.
  If SQLITE_MISUSE is raised, it is a sqlite3 module bug. Users of the
  sqlite3 module are not responsible for using the SQLite C API correctly.
* Don't overwrite BufferError with ValueError when conversion to BLOB fails.
* Raise ProgrammingError instead of Warning if user tries to execute() more
  than one SQL statement.
* Raise ProgrammingError instead of ValueError if an SQL query contains null characters.
* Make sure `_pysqlite_set_result` raises an exception if it returns -1.
