Updated the decimal package's min() and max() methods to match the latest revision of the General Decimal Arithmetic Specification. Quiet NaNs are ignored and equal values are sorted based on sign and exponent. The decimal package's Context.copy() method now returns deep copies.

  • Towards a Standard Parser Generator

    Towards a Standard Parser Generator Towards a Standard Parser Generator Martin v. Löwis Humboldt-Universität zu Berlin Institut für Informatik loewis@informatik.hu-berlin.de Abstract Developing parsers for "little" languages is a common task for many software developers. People have frequently requested inclusion of a specific parser generator framework into the Python library. In this paper, we compare several Python parser generators, using the XPath langua...

  • Parade of the PEPs

    ...Requests - Hylton Frankly, this is mostly a dumpster for "would be nice" ideas that don't have enough priority to ever get implemented. It seems nobody ever goes through this and finds a nice idea for which they write the code and submit a patch. So in effect, an idea that is moved to PEP 42 is worse off than one that is outright rejected -- it's in a zombie zone from which there is no possible escape either to heaven or to hell. How can we change this? PEP 206 - 2.0 Batteries I...

    ...requests yearly. In 2019 the Grants Program provided $324,500 USD in support to initiatives around the world. This support requires substantial accounting work and since the PSF is a non-profit organization, it is vital that our accounting roles are staffed adequately as we continue to grow the support we provide for the Python community. This not only helps us handle incoming and outgoing grants, but also provides better support for our Fiscal Sponsorees. At the beginning of 2019 we hired two f...

Core Fixed two bugs reported as SF #535905: under certain conditions, deallocating a deeply nested structure could cause a segfault in the garbage collector, due to interaction with the "trashcan" code; access to the current frame during destruction of a local variable could access a pointer to freed memory. SF #457466: popenx() argument mangling hangs python (win9x only). Under certa...
