Changes to debug() function:

2021-10-14T20:52:32+00:00

* use str() if exception derives from OSError / EnvironmentError. This
way we will print the file name (if it exists).
* use repr() for any other exception
* add tests for debug() function
* backport contextlib.redirect_stderr

Handle ENAMETOOLONG on Linux (#1940) (#1955)

2021-10-05T18:13:38+00:00

When resolving process file descriptors symlinks in procfs (/proc/PID/fd/FD),
the kernel can only deal with file paths no longer than PAGE_SIZE
(which usually equals to PATH_MAX).

https://elixir.bootlin.com/linux/v5.12/source/fs/proc/base.c#L1759

Resolving fd symlink that corresponds to a file with a path longer
than PATH_MAX with readlink(2) would result in ENAMETOOLONG error
(see details in #1940).

We can do nothing to fix this in userspace; therefore these errors
should be ignored.

Improve custom error tracebacks and messages (#1992)

2021-10-03T13:55:16+00:00

Removal of duplicated `psutil.NoSuchProcess` text. Before:

```
psutil.NoSuchProcess: psutil.NoSuchProcess process no longer exists (pid=4651, name="python")
psutil.ZombieProcess: psutil.ZombieProcess process no longer exists and it's a zombie (pid=4651, name="python")
psutil.AccessDenied: psutil.AccessDenied (pid=4651, name="python")
psutil.TimeoutExpired: psutil.TimeoutExpired timeout after 5 seconds (pid=4651, name="python")
```

Now:

```
psutil.NoSuchProcess: process no longer exists (pid=4651, name="python")
psutil.ZombieProcess: process no longer exists and it's a zombie (pid=4651, name="python")
psutil.AccessDenied: (pid=4651, name="python")
psutil.TimeoutExpired: timeout after 5 seconds (pid=4651, name="python")

```

More info if process PID has been reused: Before:

```
psutil.NoSuchProcess: psutil.NoSuchProcess process no longer exists (pid=465148)
```

Now:

```
psutil.NoSuchProcess: process no longer exists and its PID has been reused (pid=465148)
```

---

Before:

```
psutil.NoSuchProcess: psutil.NoSuchProcess no process found with pid 666
```

Now:

```
psutil.NoSuchProcess: process PID not found (pid=666)
```

--- 

Before:

```
>>> psutil.NoSuchProcess(212, name="python")
psutil.NoSuchProcess process no longer exists (pid=212, name='python')
```

Now:

```
>>> psutil.NoSuchProcess(212, name="python")
psutil.NoSuchProcess(pid=212, name='python', msg='process no longer exists')
```
