[issue28708] Low FD_SETSIZE limit on Windows

Steve Dower added the comment: It looks like Modules/selectmodule.c already has the handling for when this gets large (and we really want to stop allocating the static array on the stack), which is a plus, but I'd want to see the performance cost to small selects if suddenly we're allocating 1

[issue28707] add 'directory' option to the http.server module

Julien Palard added the comment: Hi Stéphane, Your patch is simple and elegant, but I'm asking myself a question about the idea to pass a class instead of an instance to the TCPServer ctor (I know that's not your choice). If we were able to pass an instance of SimpleHTTPRequestHandler instead

[issue28709] PyStructSequence_NewType is broken

New submission from Josh Rosenberg: I could be missing something, but it looks like PyStructSequence_NewType is guaranteed broken. Specifically, it allocates the memory with PyType_GenericAlloc (use PyType_Type as the base), and PyType declares itself to have garbage collected instances, so th

[issue28709] PyStructSequence_NewType is broken; makes GC type without setting Py_TPFLAGS_HEAPTYPE

Josh Rosenberg added the comment: Note: Uncommenting the line that forces Py_TPFLAGS_HEAPTYPE isn't enough, since it looks like the PyHeapTypeObject fields aren't initialized properly, causing seg faults if you access, for example, __name__/__qualname__ (or print the type's repr, which implici

[issue28710] Sphinx incompatible markup in configparser.ConfigParser.

New submission from Patrick Lehmann: Why does e.g. configparser.ConfigParser contain doc strings with Sphinx incompatible markup? The markup starts with back-tick, but ends with a single quote. Example: https://github.com/python/cpython/blob/master/Lib/configparser.py?ts=2#L26 Sphinx writes t

[issue28709] PyStructSequence_NewType is broken; makes GC type without setting Py_TPFLAGS_HEAPTYPE

Josh Rosenberg added the comment: On further checking, looks like there is a lot of work that should be done to initialize heap types (see PyType_FromSpecWithBases) that PyStructSequeuence_Init2 doesn't do (because it thinks it's working on a static type). I think the solution here is decouple
