* bpo-45947: Place dict and values pointer at fixed (negative) offset just ↵Mark Shannon2021-12-071-0/+3
| | | | | | | | | | | | | | | | | | | before GC header. (GH-29879) * Place __dict__ immediately before GC header for plain Python objects. * Fix up lazy dict creation logic to use managed dict pointers. * Manage values pointer, placing them directly before managed dict pointers. * Convert hint-based load/store attr specialization target managed dict classes. * Specialize LOAD_METHOD for managed dict objects. * Remove unsafe _PyObject_GC_Calloc function. * Remove unsafe _PyObject_GC_Malloc() function. * Add comment explaning use of Py_TPFLAGS_MANAGED_DICT.

* bpo-44035: Check autoconf files thoroughly (GH-29935)Christian Heimes2021-12-061-0/+2
| | | | | | | | | Check that users don't push changes with outdated or patched autoconf. The presence of runstatedir option and aclocal 1.16.3 are good markers. Use my container image to regenerate autoconf files. "Check for changes" will fail later when any file is regenerated. Use ccache in check_generated_files to speed up testing.

* bpo-45662: Fix the repr of InitVar with a type alias to the built-in class ↵Serhiy Storchaka2021-12-051-0/+2
| | | | | (GH-29291) For example, InitVar[list[int]].
* bpo-37295: Optimize math.comb() and math.perm() (GH-29090)Serhiy Storchaka2021-12-051-0/+1
| | | | | | | | For very large numbers use divide-and-conquer algorithm for getting benefit of Karatsuba multiplication of large numbers. Do calculations completely in C unsigned long long instead of Python integers if possible.
* bpo-27946: Fix possible crash in ElementTree.Element (GH-29915)Serhiy Storchaka2021-12-051-0/+3
| | | | | Getting an attribute via attrib.get() simultaneously with replacing the attrib dict can lead to access to deallocated dict.
* bpo-13236: Flush the output stream more often in unittest (GH-29864)Serhiy Storchaka2021-12-041-0/+2

* bpo-45950: Introduce Bootstrap Python again (#29859)Christian Heimes2021-12-031-0/+4
| | | | | | | | | The build system now uses a :program:`_bootstrap_python` interpreter for freezing and deepfreezing again. To speed up build process the build tools :program:`_bootstrap_python` and :program:`_freeze_module` are no longer build with LTO. Cross building depends on a build Python interpreter, which must have same version and bytecode as target host Python.
* bpo-45885: Specialize COMPARE_OP (GH-29734)Dennis Sweeney2021-12-031-0/+1
| | | | | | | * Add COMPARE_OP_ADAPTIVE adaptive instruction. * Add COMPARE_OP_FLOAT_JUMP, COMPARE_OP_INT_JUMP and COMPARE_OP_STR_JUMP specialized instructions. * Introduce and use _PyUnicode_Equal
* bpo-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-0/+3
| | | | | The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code. This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.
* bpo-45535: Improve output of Enum ``dir()`` (GH-29316)Alex Waygood2021-12-021-0/+1
| | | | | | Modify the ``EnumType.__dir__()`` and ``Enum.__dir__()`` to ensure that user-defined methods and methods inherited from mixin classes always show up in the output of `help()`. This change also makes it easier for IDEs to provide auto-completion.

* bpo-43137: webbrowser: Replace gvfs-open and gnome-open with "gio open" ↵Simon McVittie2021-11-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-29154) * [bpo-43137](): webbrowser: Prefer gio open over gvfs-open gvfs-open(1) was superseded by gio(1) in 2015, and removed from GNOME releases in 2018. Debian and its derivatives like Ubuntu currently still have a compatibility shim for gvfs-open, but we plan to remove it. webbrowser prefers xdg-settings and xdg-open over gvfs-open, so this will only have any practical effect on systems where the xdg-utils package is not installed. Note that we don't check for GNOME_DESKTOP_SESSION_ID before using gio. gio does the right thing on any desktop environment that follows freedesktop.org specifications, similar to xdg-settings, so it's unnecessary to guard in this way. GNOME_DESKTOP_SESSION_ID was deprecated in 2008 and removed from upstream gnome-session in 2018 (it's still present in Debian/Ubuntu for backward compatibility, but probably shouldn't be). The replacement way to detect a desktop environment is the XDG_CURRENT_DESKTOP environment variable, which is a colon-separated sequence where the first item is the current desktop environment and the second and subsequent items (if present) are other desktop environments that it resembles or is based on. Resolves: * [bpo-43137](): webbrowser: Never invoke gnome-open gnome-open was part of GNOME 2, which was superseded in around 2010 and is unmaintained. The replacement was gvfs-open, which was subsequently replaced by gio(1) (as used in the previous commit). * [bpo-43137](): webbrowser: Don't run gvfs-open on GNOME gvfs-open was deprecated in 2015 and removed in 2018. The replacement is gio(1) (as used in a previous commit). GNOME_DESKTOP_SESSION_ID was deprecated in 2008 and removed in 2018. The replacement is XDG_CURRENT_DESKTOP (as mentioned in a previous commit). --- To test this on a typical modern Linux system, it is necessary to disable the `xdg-settings` and `xdg-open` code paths, for example with this hack: <details><summary>Hack to disable use of xdg-settings and xdg-open</summary> ```diff diff --git a/Lib/webbrowser.py b/Lib/webbrowser.py index 3244f206aa..8f6c09d1d2 100755 --- a/Lib/webbrowser.py +++ b/Lib/webbrowser.py @@ -459,7 +459,7 @@ def open(self, url, new=0, autoraise=True): def register_X_browsers(): # use xdg-open if around - if shutil.which("xdg-open"): + if 0 and shutil.which("xdg-open"): register("xdg-open", None, BackgroundBrowser("xdg-open")) # Opens an appropriate browser for the URL scheme according to @@ -549,7 +549,7 @@ def register_standard_browsers(): # Prefer X browsers if present if os.environ.get("DISPLAY") or os.environ.get("WAYLAND_DISPLAY"): try: - cmd = "xdg-settings get default-web-browser".split() + cmd = "false xdg-settings get default-web-browser".split() raw_result = subprocess.check_output(cmd, stderr=subprocess.DEVNULL) result = raw_result.decode().strip() except (FileNotFoundError, subprocess.CalledProcessError, PermissionError, NotADirectoryError) : ``` </details> I haven't attempted to assess which of the specific web browsers such as Galeon are still extant, and which ones disappeared years ago.
