On Windows, we now determine process unique identity by using process' fast create time method. This has more chances to fail with `AccessDenied` for ADMIN owned processes, but it shouldn't matter because if we have no rights to get process ctime we'll also have no rights to accidentally `kill()` the wrong process PID anyway.

[Python 2.7] currently represents 7-10% of total downloads, aka around 70k /100k downloads per day 3 years later (and to my surprise) **downloads for Python 2.7 dropped to 0.36%**. These are downloads per month: ``` $ pypinfo --percent psutil pyversion Served from cache: False Data processed: 4.65 GiB Data billed: 4.65 GiB Estimated cost: $0.03 | python_version | percent | download_count | | -------------- | ------- | -------------- | | 3.10 | 23.84% | 26,354,506 | | 3.8 | 18.87% | 20,862,015 | | 3.7 | 17.38% | 19,217,960 | | 3.9 | 17.00% | 18,798,843 | | 3.11 | 13.63% | 15,066,706 | | 3.12 | 7.01% | 7,754,751 | | 3.13 | 1.15% | 1,267,008 | | 3.6 | 0.73% | 803,189 | | 2.7 | 0.36% | 402,111 | | 3.5 | 0.03% | 28,656 | | Total | | 110,555,745 | ``` According to [pypistats.org](https://archive.is/wip/knzql) it's 0.28% of the total, and around 15.000 downloads per day. Maintaining 2.7 support has become increasingly difficult, but still possible. E.g. we can still run tests by using [old PYPI backports](https://github.com/giampaolo/psutil/blob/fbb6d9ce98f930d3d101b7df5a4f4d0f1d2b35a3/setup.py#L76-L85). GitHub Actions can still be [tweaked](https://github.com/giampaolo/psutil/blob/fbb6d9ce98f930d3d101b7df5a4f4d0f1d2b35a3/.github/workflows/build.yml#L77-L112) to run tests and produce wheels on Linux and macOS. Not Windows though, for which we have to use a separate service (Appveyor). Still, the amount of hacks in psutil source code necessary to support Python 2.7 piled up over the years, and became quite big. Some disadvantages that come to mind: * (high) having to maintain various python compatibility layers (e.g. [psutil/_compat.py](https://github.com/giampaolo/psutil/blob/fbb6d9ce98f930d3d101b7df5a4f4d0f1d2b35a3/psutil/_compat.py#L1)) + all the compromises that come with it (extra imports, extra code, str vs. unicode differences, etc.) * (medium) having to maintain a C compatibility layer (`#if PY_MAJOR_VERSION <= 3`, etc.) * (medium) inability to use modern language features, especially f-strings * (low) inability to freely use `enum`s, which creates a difference on how CONSTANTS are exposed in terms of API * (medium) having to install a specific version of pip and other (outdated) [deps](https://github.com/giampaolo/psutil/blob/fbb6d9ce98f930d3d101b7df5a4f4d0f1d2b35a3/setup.py#L76-L85) * (high) relying on third-party Appveyor CI service, just to run tests on python 2.7 and produce wheels, when we could rely on a single CI service instead (GitHub) * (high) soon I want to distribute wheels via GitHub instead of manually via `twine`, so that'll be a problem (CC @potiuk) * (high) gradual lack of support from third-party libraries and services * (medium) 4 extra CI jobs which are run on every commit (Linux, macOS, Windows 32-bit, Windows 64-bit) * (medium) the distribution of 7 wheels specific for Python 2.7. From last release: * psutil-6.1.1-cp27-cp27m-macosx_10_9_x86_64.whl * psutil-6.1.1-cp27-none-win32.whl * psutil-6.1.1-cp27-none-win_amd64.whl * psutil-6.1.1-cp27-cp27m-manylinux2010_i686.whl * psutil-6.1.1-cp27-cp27m-manylinux2010_x86_64.whl * psutil-6.1.1-cp27-cp27mu-manylinux2010_i686.whl * psutil-6.1.1-cp27-cp27mu-manylinux2010_x86_64.whl * etc. As such I decided to finally **drop support for Python 2.7**. Current psutil 6.1.1 release will still support Python 2.7, but next 7.0.0 will not. We can still make a promise that the 6.1.* line (EDIT: see [python2 branch](https://github.com/giampaolo/psutil/tree/python2)) will keep supporting Python 2.7 and will **receive critical bug-fixes only** (no new features). In 7.0.0 we can keep the [setup.py](https://github.com/giampaolo/psutil/blob/fbb6d9ce98f930d3d101b7df5a4f4d0f1d2b35a3/setup.py) script compatible with Python 2.7 in terms of syntax, so that it can emit an informative error message on pip install. E.g. the user will see something like this: ``` $ pip2 install psutil As of version 7.0.0 psutil no longer supports Python 2.7. Latest version supporting Python 2.7 is psutil 6.1.X. Install it with: "pip2 install psutil==6.1.*". ``` Related tickets: * 2017-06: https://github.com/giampaolo/psutil/issues/1053 * 2022-04: https://github.com/giampaolo/psutil/pull/2099 * 2023-04: https://github.com/giampaolo/psutil/pull/2246 * https://github.com/giampaolo/pyftpdlib/pull/635 --- .github/workflows/build.yml | 57 +-- .github/workflows/issues.py | 5 +- HISTORY.rst | 14 + INSTALL.rst | 1 -

In practical terms, this is what changes: # Shorter tracebacks When adding the full traceback info adds no value, we now shorten tracebacks if `raise X from None`. A similar (hackish) attempt was made in https://github.com/giampaolo/psutil/commit/633d8019, when we were still stuck with Python 2. The notable example is passing a PID that does not exist to the `Process` class: ```python psutil.Process(333) ``` Before we got: ``` Traceback (most recent call last): File "/home/giampaolo/svn/psutil/psutil/_pslinux.py", line 1647, in wrapper return fun(self, *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/_common.py", line 464, in wrapper raise err from None File "/home/giampaolo/svn/psutil/psutil/_common.py", line 462, in wrapper return fun(self) ^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/_pslinux.py", line 1713, in _parse_stat_file data = bcat(f"{self._procfs_path}/{self.pid}/stat") ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/_common.py", line 794, in bcat return cat(fname, fallback=fallback, _open=open_binary) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/_common.py", line 782, in cat with _open(fname) as f: ^^^^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/_common.py", line 746, in open_binary return open(fname, "rb", buffering=FILE_READ_BUFFER_SIZE) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ FileNotFoundError: [Errno 2] No such file or directory: '/proc/341244/stat' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/home/giampaolo/svn/psutil/psutil/__init__.py", line 350, in _init self._ident = self._get_ident() ^^^^^^^^^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/__init__.py", line 391, in _get_ident return (self.pid, self.create_time()) ^^^^^^^^^^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/__init__.py", line 773, in create_time self._create_time = self._proc.create_time() ^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/_pslinux.py", line 1647, in wrapper return fun(self, *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/_pslinux.py", line 1885, in create_time ctime = float(self._parse_stat_file()['create_time']) ^^^^^^^^^^^^^^^^^^^^^^^ File "/home/giampaolo/svn/psutil/psutil/_pslinux.py", line 1659, in wrapper raise NoSuchProcess(pid, name) from err psutil.NoSuchProcess: process no longer exists (pid=341244) During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/giampaolo/svn/psutil/foo.py", line 5, in psutil.Process(341244) File "/home/giampaolo/svn/psutil/psutil/__init__.py", line 317, in __init__ self._init(pid) File "/home/giampaolo/svn/psutil/psutil/__init__.py", line 363, in _init raise NoSuchProcess(pid, msg=msg) psutil.NoSuchProcess: process PID not found (pid=341244) ``` Now we get: ``` Traceback (most recent call last): File "/home/giampaolo/svn/psutil/foo.py", line 5, in psutil.Process(341244) File "/home/giampaolo/svn/psutil/psutil/__init__.py", line 317, in __init__ self._init(pid) File "/home/giampaolo/svn/psutil/psutil/__init__.py", line 363, in _init raise NoSuchProcess(pid, msg=msg) from None psutil.NoSuchProcess: process PID not found (pid=341244) ``` # Different wording for "translated" exceptions By "translated" I mean psutil's `NoSuchProcess`, `ZombieProcess` and `AccessDenied`.
