…H-12331) Fix an unlikely memory leak on conversion from string to float in the function _Py_dg_strtod() used by float(str), complex(str), pickle.load(), marshal.load(), etc. Fix an unlikely memory leak in _Py_dg_strtod() on "undfl:" label: rewrite memory management in this function to always release all memory before exiting the function. Initialize variables to NULL, and set them to NULL after calling Bfree() at the "cont:" label. Note: Bfree(NULL) is well defined: it does nothing. (cherry picked from commit 9776b06)
…H-12348) Fix CFLAGS in customize_compiler() of distutils.sysconfig: when the CFLAGS environment variable is defined, don't override CFLAGS variable with the OPT variable anymore.

Ensure that _PyRuntime_Finalize() is always call. This change fix a few memory leaks when running "python3 -V".
At Python initialization, the current directory is no longer prepended to sys.path if it has been removed.
Replace strncpy() with memcpy() in call_readline() to fix the
following warning, the NUL byte is written manually just after:
Modules/readline.c: In function ‘call_readline’:
Modules/readline.c:1303:9: warning: ‘strncpy’ output truncated before
terminating nul copying as many bytes from a string as its length
[-Wstringop-truncation]
strncpy(p, q, n);
^~~~~~~~~~~~~~~~
Modules/readline.c:1279:9: note: length computed here
n = strlen(p);
^~~~~~~~~

bpo-36256: Fix bug in parsermodule when parsing if statements In the parser module, when validating nodes before starting the parsing with to create a ST in "parser_newstobject" there is a problem that appears when two arcs in the same DFA state has transitions with labels with the same type. For example, the DFA for if_stmt has a state with two labels with the same type: "elif" and "else" (type NAME). The algorithm tries one by one the arcs until the label that starts the arc transition has a label with the same type of the current child label we are trying to accept. In this case, the arc for "elif" comes before the arc for "else"and passes this test (because the current child label is "else" and has the same type as "elif"). This lead to expecting a namedexpr_test (305) instead of a colon (11). The solution is to compare also the string representation (in case there is one) of the labels to see if the transition that we have is the correct one.

Hello, and thanks for your contribution! I'm a bot set up to make sure that the project can legally accept your contribution by verifying you have signed the PSF contributor agreement (CLA). Unfortunately we couldn't find an account corresponding to your GitHub username on bugs.python.org (b.p.o) to verify you have signed the CLA (this might be simply due to a missing "GitHub Name" entry in your b.p.o account settings). This is necessary for legal reasons before we can look at your contribution. Please follow the steps outlined in the CPython devguide to rectify this issue. You can check yourself to see if the CLA has been received. Thanks again for your contribution, we look forward to reviewing it! |
