[PATCH v4 00/58] perf: Reorganize scripting support

[Ian Rogers <irogers@google.com>]

The perf script command has long supported running Python and Perl scripts by
embedding libpython and libperl. This approach has several drawbacks:
 - overhead by creating Python dictionaries for every event (whether used or
   not),
 - complex build dependencies on specific Python/Perl versions,
 - complications with threading due to perf being the interpreter,
 - no clear way to run standalone scripts like ilist.py.

This series takes a different approach with some initial implementation posted
as an RFC last October:
https://lore.kernel.org/linux-perf-users/20251029053413.355154-1-irogers@google.com/
with the motivation coming up on the mailing list earlier:
https://lore.kernel.org/lkml/CAP-5=fWDqE8SYfOLZkg_0=4Ayx6E7O+h7uUp4NDeCFkiN4b7-w@mail.gmail.com/

The changes remove the embedded libpython and libperl support from perf
entirely. Instead, they expand the existing perf Python module to provide full
access to perf data files and events, allowing scripts to be run as standalone
Python applications.

To demonstrate the benefits, we ported all existing Python and Perl scripts to
use the new Python session API. The performance improvement is dramatic. For
example, porting mem-phys-addr.py:

Before (using embedded libpython in perf script):
```
$ perf mem record a sleep 1
$ time perf script tools/perf/scripts/python/mem-phys-addr.py
Event: cpu_core/mem-loads-aux/
Memory type                                    count  percentage
 ---------------------------------------  ----------  ----------
0-fff : Reserved                                3217       100.0

real    0m3.754s
user    0m0.023s
sys     0m0.018s
```

After (using standalone Python script with perf module):
```
$ PYTHONPATH=/tmp/perf/python time python3 tools/perf/python/mem-phys-addr.py
Event: evsel(cpu_core/mem-loads-aux/)
Memory type                                    count  percentage
 ---------------------------------------  ----------  ----------
0-fff : Reserved                                3217       100.0

real    0m0.106s
user    0m0.021s
sys     0m0.020s
```

This is a roughly 35x speedup!

The change is large (11291 insertions, 15964 deletions, net 4673
deletions) due to porting all existing perl and python code to the new
API. Gemini was used to achieve this and to improve the code
quality. Removing support may be controversial, however, the first 52
patches are additive and merging those would allow us to focus on the
remaining 6 patches that finalize the new perf script behavior.

v4 Changes
----------

Sorry for the churn resending v3 plus one fix!

1. Git Fixup Cleanups
- Squashed the lingering `fixup!` commit remaining from the previous session back
  into `perf check-perf-trace: Port check-perf-trace to use python module`.

---
v3 Changes
----------

1. Memory Safety & Reference Counting Fixes
- Stored transient mmap event data inside the Python object's permanent
  `pevent->event` and invoked `evsel__parse_sample()` to safely point
  attributes into it, resolving Use-After-Free vulnerabilities.
- Nullified `sample->evsel` after calling `evsel__put()` in
  `perf_sample__exit()` to protect against potential refcount double-put
  crashes in error paths.
- Reordered operations inside `evlist__remove()` to invoke
  `perf_evlist__remove()` before reference release.
- Patched an `evsel` reference leak inside `evlist__deliver_deferred_callchain()`.

2. Sashiko AI Review Cleanups
- Corrected the broken event name equality check in `gecko.py` to search
  for a substring match within the parsed event string.
- Fixed a latent `AttributeError` crash in `task-analyzer.py` by properly
  assigning the session instance.
- Safeguarded thread reporting in `check-perf-trace.py` by utilizing
  `sample_tid` instead of `sample_pid`, and wrapping the session thread
  resolution in a try-except block.

3. Omitted Minor Issues
- The minor review comments (such as permanent iterator exhaustion on
  `brstack`, or dead-code in `failed-syscalls-by-pid.py`) have been omitted
  because they do not affect correctness, lead to crashes, or require
  significant architectural rework.

---
v2 Changes
----------

1. String Match and Event Name Accuracy
- Replaced loose substring event matching across the script suite with exact
  matches or specific prefix constraints (syscalls:sys_exit_,
  evsel(skb:kfree_skb), etc.).
- Added getattr() safety checks to prevent script failures caused by
  unresolved attributes from older kernel traces.

2. OOM and Memory Protections
- Refactored netdev-times.py to compute and process network statistics
  chronologically on-the-fly, eliminating an unbounded in-memory list
  that caused Out-Of-Memory crashes on large files.
- Implemented threshold limits on intel-pt-events.py to cap memory allocation
  during event interleaving.
- Optimized export-to-sqlite.py to periodically commit database transactions
  (every 10,000 samples) to reduce temporary SQLite journal sizes.

3. Portability & Environment Independence
- Re-keyed internal tracking dictionaries in scripts like powerpc-hcalls.py to
  use thread PIDs instead of CPUs, ensuring correctness when threads migrate.
- Switched net_dropmonitor.py from host-specific /proc/kallsyms parsing to
  perf's built-in symbol resolution API. 
- Added the --iomem parameter to mem-phys-addr.py to support offline analysis
  of data collected on different architectures.

4. Standalone Scripting Improvements
- Patched builtin-script.c to ensure --input parameters are successfully passed
  down to standalone execution pipelines via execvp().
- Guarded against string buffer overflows during .py extension path resolving.

5. Code Cleanups
- Removed stale perl subdirectories from being detected by the TUI script
  browser.
- Ran the entire script suite through mypy and pylint to achieve strict static
  type checking and resolve unreferenced variables.
