For builtin types with builtin subclasses, help() on the type now shows up
to 4 of the subclasses. This partially replaces the exception hierarchy
information previously displayed in Python 2.7.
path_error() uses GetLastError() on Windows, but some os functions
are implemented via CRT APIs which report errors via errno.
This may result in raising OSError with invalid error code (such
as zero).
Introduce posix_path_error() function and use it where appropriate.
If buffering=1 is specified for open() in binary mode, it is silently
treated as buffering=-1 (i.e., the default buffer size).
Coupled with the fact that line buffering is always supported in Python 2,
such behavior caused several issues (e.g., bpo-10344, bpo-21332).
Warn that line buffering is not supported if open() is called with
binary mode and buffering=1.
The reprlib code was copied here instead of importing reprlib. I'm not sure if we really need to avoid the import, but since I expect dataclasses to be more common that reprlib, it seems wise. Plus, the code is small.
Adding `max_num_fields` to `cgi.FieldStorage` to make DOS attacks harder by
limiting the number of `MiniFieldStorage` objects created by `FieldStorage`.
It is now guarantied that children of xml.etree.ElementTree.Element
are Elements (at least in C implementation). Previously methods
__setitem__(), __setstate__() and __deepcopy__() could be used for
adding non-Element children.
When runnint test_logging with --huntrleaks after commit
18fb1fb943, test_out_of_order fails
to raise ValueError due to the fact that the new test
test_out_of_order_with_dollar_style mutates the out_of_order
dictionary. Even if the test copies the dictionary first, the mutation
is done in a very deep level so the original one is also affected.
Fix test_cmd_line_script.test_nonexisting_script(): the test must not
rely on sys.executable, since main.c uses config->program which can
be different than sys.executable in many cases (for example, on macOS
when using the framework).
Allow annotated global names in the module namespace after the symbol is
declared as global. Previously, only symbols annotated before they are declared
as global (i.e. inside a function) were allowed. This change allows symbols to be
declared as global before the annotation happens in the global scope.
With macOS framework builds, test case test_nonexisting_script in
test_nonexisting_script fails because the test case assumes that
the file name in sys.executable will appear in the error message.
For macOS framework builds, sys.executable is the file name of the
stub launcher and its file name bears no relationship to the file
name of the actual python executable. For now, skip the test in
this case.
Unconditional forcing of ``CHECKED_HASH`` invalidation was introduced in
3.7.0 in bpo-29708. The change is bad, as it unconditionally overrides
*invalidation_mode*, even if it was passed as an explicit argument to
``py_compile.compile()`` or ``compileall``. An environment variable
should *never* override an explicit argument to a library function.
That change leads to multiple test failures if the ``SOURCE_DATE_EPOCH``
environment variable is set.
This changes ``py_compile.compile()`` to only look at
``SOURCE_DATE_EPOCH`` if no explicit *invalidation_mode* was specified.
I also made various relevant tests run with explicit control over the
value of ``SOURCE_DATE_EPOCH``.
While looking at this, I noticed that ``zipimport`` does not work
with hash-based .pycs _at all_, though I left the fixes for
subsequent commits.
Tests involving sending signals to the semaphore_tracker will not fail anymore due to
the fact that running the test suite with -Werror propagates warnings as errors.
Fix a missing assertion when the semaphore_tracker is expected to die.
When Python is built with the intel control-flow protection flags,
-mcet -fcf-protection, gdb is not able to read the stack without
actually jumping inside the function. This means an extra
'next' command is required to make the $pc (program counter)
enter the function and make the stack of the function exposed to gdb.
