* bpo-38634: Allow non-apple build to cope with libedit (GH-16986)serge-sans-paille2019-12-041-0/+2
| | | | | | | | | | | The readline module now detects if Python is linked to libedit at runtime on all platforms. Previously, the check was only done on macOS. If Python is used as a library by a binary linking to libedit, the linker resolves the rl_initialize symbol required by the readline module against libedit instead of libreadline, which leads to a segfault. Take advantage of the existing supporting code to have readline module being compatible with both situations.

| | | | | | | (GH-17302) Add ast.unparse() as a function in the ast module that can be used to unparse an ast.AST object and produce a string with code that would produce an equivalent ast.AST object when parsed.
* bpo-38876: Raise pickle.UnpicklingError when loading an item from memo for ↵Claudiu Popa2019-11-241-0/+9
| | | | | | | | | | | | | | | invalid input (GH-17335) The previous code was raising a `KeyError` for both the Python and C implementation. This was caused by the specified index of an invalid input which did not exist in the memo structure, where the pickle stores what objects it has seen. The malformed input would have caused either a `BINGET` or `LONG_BINGET` load from the memo, leading to a `KeyError` as the determined index was bogus. https://bugs.python.org/issue38876 https://bugs.python.org/issue38876
* Better runtime TypedDict (GH-17214)Zac Hatfield-Dodds2019-11-241-0/+3
| | | | | This patch enables downstream projects inspecting a TypedDict subclass at runtime to tell which keys are optional. This is essential for generating test data with Hypothesis or validating inputs with typeguard or pydantic.

* bpo-38686: fix HTTP Digest handling in request.py (#17045)PypeBros2019-11-221-0/+1
| | | | | | | | | | | | | | | | | | | | | * fix HTTP Digest handling in request.py There is a bug triggered when server replies to a request with `WWW-Authenticate: Digest` where `qop="auth,auth-int"` rather than mere `qop="auth"`. Having both `auth` and `auth-int` is legitimate according to the `qop-options` rule in §3.2.1 of [[https://www.ietf.org/rfc/rfc2617.txt|RFC 2617]]: > qop-options = "qop" "=" <"> 1#qop-value <"> > qop-value = "auth" | "auth-int" | token > **qop-options**: [...] If present, it is a quoted string **of one or more** tokens indicating the "quality of protection" values supported by the server. The value `"auth"` indicates authentication; the value `"auth-int"` indicates authentication with integrity protection This is description confirmed by the definition of the [//n//]`#`[//m//]//rule// extended-BNF pattern defined in §2.1 of [[https://www.ietf.org/rfc/rfc2616.txt|RFC 2616]] as 'a comma-separated list of //rule// with at least //n// and at most //m// items'. When this reply is parsed by `get_authorization`, request.py only tests for identity with `'auth'`, failing to recognize it as one of the supported modes the server announced, and claims that `"qop 'auth,auth-int' is not supported"`. * 📜🤖 Added by blurb_it. * bpo-38686 review fix: remember why. * fix trailing space in Lib/urllib/request.py Co-Authored-By: Brandt Bucher <brandtbucher@gmail.com>
* bpo-38863: Improve is_cgi() in http.server (GH-17312)Siwon Kang2019-11-221-0/+2
| | | | | | | | | | | | | | | | | | | is_cgi() function of http.server library does not currently handle a cgi script if one of the cgi_directories is located at the sub-directory of given path. Since is_cgi() in CGIHTTPRequestHandler class separates given path into (dir, rest) based on the first seen '/', multi-level directories like /sub/dir/cgi-bin/hello.py is divided into head=/sub, rest=dir/cgi-bin/hello.py then check whether '/sub' exists in cgi_directories = [..., '/sub/dir/cgi-bin']. This patch makes the is_cgi() keep expanding dir part to the next '/' then checking if that expanded path exists in the cgi_directories.

* closes bpo-38712: Add signal.pidfd_send_signal. (GH-17070)Benjamin Peterson2019-11-201-0/+3
| | | | | | | | This exposes a Linux-specific syscall for sending a signal to a process identified by a file descriptor rather than a pid. For simplicity, we don't support the siginfo_t parameter to the syscall. This parameter allows implementing a pidfd version of rt_sigqueueinfo(2), which Python also doesn't support.
