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.
---
v7 Changes
----------
- Fixed heap out-of-bounds in `pyrf_event__new` by adding comprehensive
size checks for all event types.
- Fixed undefined symbol `syscalltbl__id` when building without
libtraceevent by making `syscalltbl.o` unconditional in `Build`.
- Fixed several issues in `python.c`:
- Handled NULL return from `thread__comm_str` in `pyrf_thread__comm`.
- Avoided swallowing exceptions in module initialization.
- Added custom `tp_new` methods for `evlist`, `evsel`, and `data` types
to zero-initialize pointers and avoid crashes on re-initialization.
- Fixed lower priority review comments:
- Avoided permanent iterator exhaustion on `brstack` in
`perf_brstack_max.py` by converting it to a list.
- Removed dead code (unused `self.unhandled` dictionary) in
`failed-syscalls-by-pid.py`.
v6 Changes
----------
- Refactored `pyrf_event__new` to take `evsel` and `session` arguments,
and use dynamic allocation based on the actual event size to improve
memory safety and efficiency.
- Moved callchain and branch stack resolution logic from
`pyrf_session_tool__sample` into `pyrf_event__new`, centralizing
initialization.
- Added an optional keyword-only `elf_machine` argument to `syscall_name`
and `syscall_id` functions to allow specifying non-host architectures,
defaulting to `EM_HOST`.
- Renamed `process` method to `find_thread` in the Python API and C
implementation for better intention-revealing naming.
- Fixed a terminal injection vulnerability in `flamegraph.py` by not
printing unverified downloaded content in the prompt.
- Fixed CWD exposure and symlink attack risks in `gecko.py` by using a
secure temporary directory for the HTTP server.
- Fixed a severe performance issue in `event_analyzing_sample.py` by
removing SQLite autocommit mode and batching commits.
- Fixed `AttributeError` crashes in `rw-by-file.py` and `rw-by-pid.py` by
correctly extracting event names.
- Fixed man page formatting issues in `perf-script-python.txt` by using
indented code blocks.
- Updated `perf.pyi` stubs file to reflect all API changes.
- Verified all commit messages with `checkpatch.pl` and ensured lines are
wrapped appropriately.
- Fixed segmentation faults in `perf sched stats` in diff mode.
v5 Changes
----------
Resending due to partial send of v4 due to a quota limit.
v4 Changes
----------
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.
