Hi Arnaldo,
Thanks for the prompt review and feedback.
I've addressed the 'show_arg_names' consistency in the next iteration.
You can find the updated version here [1].

perf python: Handle Py_None for thread and cpu maps
The python stubs allow passing None for threads and cpus to the
perf.parse_events() and perf.parse_metrics() bindings. Because the C
code lacked an explicit check for Py_None, it would cast Py_None to a
struct pointer and dereference it. This commit explicitly checks for
Py_None alongside NULL in pyrf__parse_events, pyrf__parse_metrics, and
pyrf_evsel__open.

[Severity: Medium]
This is a pre-existing issue, but does this blind cast lack a type check?
If the Python caller passes an object that isn't a pyrf_thread_map or Py_None
(such as an integer or a string), PyArg_ParseTuple with the "O" format
specifier will accept it. When cast here, couldn't this cause memory
corruption by reading arbitrary memory as a C pointer?

This is a pre-existing issue, but is a type check also needed here in
pyrf__parse_events() before casting pthreads and pcpus to their respective C
structures?

[Severity: Medium]
This isn't a bug introduced by this patch, but does the err object leak
its internal allocations?
In tools/perf/util/python.c:pyrf__parse_events():
parse_events_error__init(&err);
perf_evlist__set_maps(evlist__core(evlist), cpus, threads);
if (parse_events(evlist, input, &err)) {
...
return NULL;
}
result = pyrf_evlist__from_evlist(evlist);
evlist__put(evlist);
return result;
Since parse_events() can allocate error/warning strings inside err, should
parse_events_error__exit(&err) be called before returning?

[Severity: Medium]
Does intel_pt_synth_ptwrite_sample() also need a call to perf_sample__exit()
to prevent an evsel reference leak?
In intel_pt_synth_ptwrite_sample(), a stack-allocated struct perf_sample is
initialized and passed to intel_pt_deliver_synth_event(). This eventually
calls machines__deliver_event(), which was modified by this patch to
populate sample.evsel and increment its reference count via evsel__get().
Because intel_pt_synth_ptwrite_sample() returns the result of the delivery
without calling perf_sample__exit(&sample) afterward to drop the dynamically
acquired evsel reference, does this cause a memory leak?

[Severity: High]
Does this delete the newly added tracked source file python/perf.pyi when
building in the source tree?
When a user builds and cleans within the source tree without specifying O=
or OUTPUT=, the $(OUTPUT) variable is empty. Consequently,
$(OUTPUT)python/perf.pyi evaluates exactly to python/perf.pyi relative
to the tools/perf/ directory, which causes make clean to blindly delete the
tracked source code.

[Severity: Medium]
Are these classes and constant exported by the underlying C extension?
The new perf.pyi file documents the constant COUNT_HW_REF_CPU_CYCLES and
classes thread, callchain, and callchain_node as being available at the
module level.
However, COUNT_HW_REF_CPU_CYCLES is missing from the PERF_CONST() definitions
in tools/perf/util/python.c. Similarly, the classes pyrf_thread__type,
pyrf_callchain__type, and pyrf_callchain_node__type do not appear to be
exported to the module namespace via PyModule_AddObject() in the PyInit_perf
function.
Will developers relying on the type stub encounter an AttributeError when
attempting to use these module-level attributes for runtime type checking
or direct references?

[Severity: Medium]
Could this broad exception block mask legitimate event parsing failures?
The underlying C extension pyrf_event__new() also raises a TypeError for
unsupported event types ("Unexpected header type") or malformed data
("Unexpected event size").
By catching all TypeErrors and assuming the CPU is unmapped, does this risk
silently ignoring corrupted or unhandled events and prematurely breaking the
processing loop for that CPU?

[Severity: High]
Can this TOCTOU race condition lead to a double free of the evlist?
If two threads concurrently drop their external references, and the total
refcount drops to 1, both threads might enter this retry loop concurrently.
If both read count = 1 and ref_cnt = 1, and both verify that the 1 remaining
reference belongs to the evsel (decrementing their local count to 0), they
will both check refcount_read() != ref_cnt (which evaluates to false).
Both threads would then proceed to the out_delete block, concurrently
executing the teardown sequence (evlist__purge, etc.) and freeing the
evlist.

> + /*
> + * Not the last reference except for back references from

[Severity: Medium]
Does this asymmetric cycle collection cause a permanent memory leak if an
external reference to an evsel is dropped after its parent evlist is dropped?
The logic here handles cycle breaking if evsels have refcnt == 1. However,
if an external component (like Python bindings via pyrf_evlist__add) holds
a reference to an evsel, its refcnt is elevated (e.g., 2). If the external
reference to the evlist is dropped first, evlist__put sees the elevated
evsel->refcnt, aborts cycle collection, and returns without freeing the
evlist.
Later, when the external reference to the evsel is dropped, evsel__put
merely decrements evsel->refcnt to 1. Because evsel__put lacks symmetric
cycle-breaking logic, neither structure ever reaches a refcount of 0.

[Severity: High]
When processing a perf.data file collected on a machine with a different
endianness, will this result in double byte-swapping the event payload?
The perf_session__deliver_event() function already calls evsel__parse_sample()
before delivering the event to the tool callback. For cross-endian files
where evsel->needs_swap is true, this performs an in-place byte-swap on the
event payload.
By copying the already-swapped event and passing it into evsel__parse_sample()
a second time here, the in-place swap will run again. Does this revert
native-endian fields back to the foreign endianness, exposing corrupted data
to the python scripts?
Could we avoid this second parse or rely on the already parsed sample
provided in the arguments?

Author: Ian Rogers <irogers@google.com>
perf python: Refactor and add accessors to sample event
This commit refactors the Python perf module to add a common evsel field for
events and limits sample-specific fields to sample events. It also introduces
lazily evaluated accessors for sample events (like symbol, dso, srccode)
and ensures memory allocation is sized appropriately for the copied events.

[Severity: Medium]
Does hardcoding the host machine here break address resolution for guest
samples?
If the perf.data file contains guest samples, it appears this will resolve
the sample against the host kernel's symbol tables instead of the guest's.
Should this code dynamically look up the appropriate machine based on the
sample, rather than assuming session->machines.host?

* [PATCH v17 20/20] perf python: Add LiveSession helper
From: Ian Rogers @ 2026-06-13 7:11 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,
linux-kernel, linux-perf-users, mingo, peterz, tmricht
In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Add LiveSession class in tools/perf/python/perf_live.py to support
live event collection using perf.evlist and perf.parse_events,
avoiding the need to fork a separate perf record process.
Signed-off-by: Ian Rogers <irogers@google.com>
Assisted-by: Gemini:gemini-3.1-pro-preview
---
v12:
- Fixed `setup_python.sh` `PYTHONPATH` prepend logic to cleanly append to existing paths.
v2:
1. Fixed File Descriptor Leak: I moved self.evlist.mmap() inside the
try block so that if it raises an exception, the finally block will
still be executed and call self.evlist.close() , preventing file
descriptor leaks.
2. Handled InterruptedError in poll() : I wrapped the poll() call in a
try-except block to catch InterruptedError and continue the
loop. This prevents the live session from crashing on non-fatal
signals like SIGWINCH .
3. Added evlist.config() : I added a call to self.evlist.config() in
the constructor after parse_events() . This applies the default
record options to the events, enabling sampling and setting up
PERF_SAMPLE_* fields so that the kernel will actually generate
PERF_RECORD_SAMPLE events.
4. Enable the evlist and be robust to exceptions from reading unsupported
events like mmap2.
v8:
- Drain all events from a CPU before moving to the next.

* [PATCH v17 19/20] perf python: Add perf.pyi stubs file
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,

In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Add Python type stubs for the perf module to improve IDE support and
static analysis. Includes docstrings for classes, methods, and
constants derived from C source and JSON definitions.
Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>
---
v12:
- Audited all `perf.pyi` event stubs: added full `sample_members` attributes (`pid`, `tid`, `time`, `id`, `stream_id`, `period`, `cpu`) to all payload events via inheritance. Fixed `sample_event` unique fields (`ip`, `addr`, `phys_addr`, `weight`, `data_src`, `insn_cnt`, `cyc_cnt`). Renamed `mmap_event.addr` to `start`. Removed `read_event.value`.
v2:
1. Added Missing Module Functions: Added parse_metrics and
pmus. Renamed metrics to parse_metrics to match python.c .
2. Added Constructors: Added __init__ methods for data , evsel , and
evlist with their appropriate arguments.
3. Removed sample_comm : Removed it from sample_event since it is not
exported in python.c .
4. Keyword Handling in branch_entry : I used from_ip and to_ip in the
stubs to match the rename I did in python.c (in turn 145) to avoid
the Python from keyword conflict.
5. Added Missing Event Classes: Added mmap_event , lost_event ,
comm_event , task_event , throttle_event , read_event , and
switch_event .
6. Added Missing evlist Methods: Added get_pollfd and add .
7. Updated Return Types: Changed process_events to return int .
v6:
- Updated `perf.pyi` to use `find_thread` and `elf_machine`.
v8:
- Added mmap2_event class and new evsel attributes to perf.pyi.
- Added pid, tid, ppid, cpu attributes to class thread in perf.pyi.

* [PATCH v17 18/20] perf python: Handle Py_None for thread and cpu maps
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,

In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
The python stubs allow passing None for threads and cpus to the
perf.parse_events() and perf.parse_metrics() bindings. However, PyArg_ParseTuple
parses None into a Py_None object, which is not a NULL pointer.
Because the C code lacked an explicit check for Py_None, it would cast
Py_None to a pyrf_thread_map/pyrf_cpu_map struct pointer and dereference it,
causing a memory corruption crash.
Fix this pre-existing issue by explicitly checking for Py_None alongside NULL
in pyrf__parse_events, pyrf__parse_metrics, and pyrf_evsel__open.

* [PATCH v17 16/20] perf python: Add syscall name/id to convert syscall number and name
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,
linux-kernel, linux-perf-users, mingo, peterz, tmricht
In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Use perf's syscalltbl support to convert syscall number to name
assuming the number is for the host machine. This avoids python
libaudit support as tools/perf/scripts/python/syscall-counts.py
requires.
Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>
---
v2:
1. Guarded with HAVE_LIBTRACEEVENT : Wrapped the syscall functions and
their entries in perf__methods with #ifdef HAVE_LIBTRACEEVENT to
avoid potential linker errors if CONFIG_TRACE is disabled.
2. Changed Exception Type: Updated pyrf__syscall_id to raise a
ValueError instead of a TypeError when a syscall is not found.
3. Fixed Typo: Corrected "name number" to "name" in the docstring for
syscall_id.
v6:
- Added optional keyword-only `elf_machine` argument to `syscall_name`
and `syscall_id`.
v7:
- Made syscalltbl.o unconditional in Build to fix undefined symbol
when building without libtraceevent.

* [PATCH v17 15/20] perf python: Expose brstack in sample event
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,

In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Implement pyrf_branch_entry and pyrf_branch_stack for lazy
iteration over branch stack entries.
Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>
---
v2:
1. Avoided Keyword Collision: Renamed the properties "from" and "to"
to "from_ip" and "to_ip" in pyrf_branch_entry__getset[] to prevent
syntax errors in Python.
2. Eager Branch Stack Resolution: Updated pyrf_session_tool__sample()
to allocate and copy the branch stack entries eagerly when the
event is processed, instead of deferring it to iteration time. This
avoids reading from potentially overwritten or unmapped mmap
buffers.
3. Updated Iterators: Updated pyrf_branch_stack and
pyrf_branch_stack__next() to use the copied entries rather than
pointing directly to the sample's buffer.
4. Avoided Reference Leak on Init Failure: Added proper error checking
for PyModule_AddObject() in the module initialization function,
decrementing references on failure.
v6:
- Moved branch stack resolution from `session_tool__sample` to
`pyrf_event__new`.

* [PATCH v17 14/20] perf python: Extend API for stat events in python.c
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,
linux-kernel, linux-perf-users, mingo, peterz, tmricht
In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Add stat information to the session. Add call backs for stat events.
Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>
---
v12:
- Made `psession->tool.stat = perf_event__process_stat_event;` conditional on `!stat` so it doesn't unconditionally overwrite user stat callbacks.
v5:
1. Fix Memory Corruption: Corrected the memory offset for `stat_round_type`
in `pyrf_stat_round_event__members` by adding the base offset of
`struct pyrf_event`.
2. Fix Memory Leak: Added `Py_XDECREF()` to free the unused return value
of the Python callback in `pyrf_session_tool__stat_round()`.
---
v7:
- Added comprehensive size checks in pyrf_event__new for all event
types.
- Fixed line length warning.
v10:
- Added CHECK_INITIALIZED check to pyrf_evsel__get_ids to prevent
NULL pointer dereference on uninitialized evsel objects.

* [PATCH v17 13/20] perf python: Add callchain support
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,
linux-kernel, linux-perf-users, mingo, peterz, tmricht
In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Implement pyrf_callchain_node and pyrf_callchain types for lazy
iteration over callchain frames. Add callchain property to
sample_event.
Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>
---
v12:
- Added an optional `struct machine *` argument to `pyrf_event__new` defaulting to the host machine if NULL, avoiding regressions for future phases.
v2:
1. Eager Callchain Resolution: Moved the callchain resolution from
deferred iteration to eager processing in
pyrf_session_tool__sample() . This avoids risks of reading from
unmapped memory or following dangling pointers to closed sessions.
2. Cached Callchain: Added a callchain field to struct pyrf_event to
store the resolved object.
3. Simplified Access: pyrf_sample_event__get_callchain() now just
returns the cached object if available.
4. Avoided Double Free: Handled lazy cleanups properly.
v6:
- Moved callchain resolution from `session_tool__sample` to
`pyrf_event__new`.

* [PATCH v17 12/20] perf python: Add mmap2 event
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,

In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
If mmap is handled so should mmap2 events. Add support as a distinct
python event type.
Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>

v12:
- Used `copy_size` to bound `max_len` for NUL termination of mmap2 and comm events to fix an out-of-bounds write.

* [PATCH v17 11/20] perf python: Refactor and add accessors to sample event
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,
linux-kernel, linux-perf-users, mingo, peterz, tmricht
In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Add common evsel field for events and move sample specific fields to
only be present in sample events. Add accessors for sample
events. Ensure offsets are within the bounds of the event. Allocate
just enough memory for the copied event, don't make the maximum event
size each time.
Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>
---
v12:
- Used `copy_size` to bound `max_len` for NUL termination to fix an out-of-bounds write in `pyrf_event__new`. Also set `pevent->event.header.size = copy_size`.
v5:
1. Fix Uninitialized Memory: Restore zero-initialization of `pevent->sample`
in `pyrf_event__new()` to prevent wild free crashes on error paths.
v6:
- Refactored `pyrf_event__new` to take `evsel` and `session`, and use
dynamic allocation based on event size. Updated callers.
v8:
- Ensure events are properly deallocated.
v11:
- Use `perf_event__too_small` for event size validation, sharing logic
with the session parser instead of replicating validation checks.

* [PATCH v17 10/20] perf python: Add python session abstraction wrapping perf's session
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,
linux-kernel, linux-perf-users, mingo, peterz, tmricht
In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Sessions are necessary to be able to use perf.data files within a
tool. Add a wrapper python type that incorporates the tool. Allow a
sample callback to be passed when creating the session. When
process_events is run this callback will be called, if supplied, for
sample events.
An example use looks like:
```
$ perf record -e cycles,instructions -a sleep 3
$ PYTHONPATH=..../perf/python python3
Python 3.13.7 (main, Aug 20 2025, 22:17:40) [GCC 14.2.0] on linux

... def handle_sample(x):
... global count
... if count < 3:
... print(dir(x))
... count = count + 1
... perf.session(perf.data("perf.data"),sample=handle_sample).process_events()

```
Also, add the ability to get the thread associated with a session. For
threads, allow the comm string to be retrieved. This can be useful for
filtering threads. Connect up some of the standard event handling in
psession->tool to better support queries of the machine. Also connect
up the symbols.

v2:
1. Fixed Potential Crash in pyrf_thread__comm : Used
thread__comm_str() to safely retrieve the command name, avoiding a
crash if thread__comm() returns NULL.
2. Fixed Double Free Risk: Zeroed out user_regs , intr_regs , and
callchain in the shallow copy of perf_sample to prevent Python from
attempting to free pointers it doesn't own.
3. Fixed Memory Leak & Exception Handling in Callback: Handled the
return value of PyObject_CallFunction() to avoid leaks, and checked
for failure to abort the loop and propagate Python exceptions
cleanly.
4. Enforced Type Safety: Used O! with &pyrf_data__type in
PyArg_ParseTupleAndKeywords to prevent bad casts from passing
arbitrary objects as perf.data.
5. Added Missing Build ID Handler: Registered
perf_event__process_build_id to allow correct symbol resolution.
6. Fixed Double Free Crash on Init Failure: Set session and pdata to
NULL on failure to prevent tp_dealloc from double-freeing them.
7. Preserved C-level Errors: Made pyrf_session__process_events return
the error code integer rather than always returning None .
v7:
- Fixed NULL comm handling.
- Avoided swallowing exceptions in module init.
- Fixed checkpatch warning for missing blank line.
v8:
- Switch from pyrf_session__init to pyrf_session__new to avoid dealing with a
potentially NULL session variable.
- Added pid, tid, ppid, and cpu attributes to perf.thread.
v10:
- Added CHECK_INITIALIZED checks to pyrf_session methods to prevent
NULL pointer dereferences on uninitialized objects.

* [PATCH v17 09/20] perf python: Add wrapper for perf_data file abstraction
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,
linux-kernel, linux-perf-users, mingo, peterz, tmricht
In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
The perf_data struct is needed for session supported.
Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>
---
v2:
1. Fixed Memory & FD Leaks in pyrf_data__init : Added cleanup of old
state (closing file and freeing path) if __init__ is called
multiple times on the same object.
2. Fixed Invalid Free in pyrf_data__delete : Ensured pdata->data.path
is always dynamically allocated via strdup() , even for the default
"perf.data" . This avoids passing a static string literal to free().
3. Fixed NULL Pointer Dereference in pyrf_data__str : Added a check
for NULL path to prevent segfaults if str() or repr() is called on
an uninitialized object.
4. Guarded fd Argument Usage: Added a check to ensure that if an fd is
provided, it corresponds to a pipe, failing gracefully with a
ValueError otherwise.
v7:
- Added pyrf_data__new to zero-initialize pdata->data to fix
crash on re-initialization.

* [PATCH v17 08/20] perf python: Use evsel in sample in pyrf_event
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,

In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Avoid a duplicated evsel by using the one in sample. Add
evsel__get/put to the evsel in perf_sample.
Signed-off-by: Ian Rogers <irogers@google.com>
---
v12:
- Removed an extra `evsel__get` in `evsel__parse_sample` to fix a reference leak on error paths.

* [PATCH v17 07/20] perf evlist: Add reference count checking
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,
linux-kernel, linux-perf-users, mingo, peterz, tmricht
In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
Now the evlist is reference counted, add reference count checking so
that gets and puts are paired and easy to debug. Reference count
checking is documented here:
https://perfwiki.github.io/main/reference-count-checking/
This large patch is adding accessors to evlist functions and switching
to their use. There was some minor renaming as evlist__mmap is now an
accessor to the mmap variable, and the original evlist__mmap is
renamed to evlist__do_mmap.
Signed-off-by: Ian Rogers <irogers@google.com>
---
v12:
- Fixed `evlist__put` cycle collection TOCTOU double free race by checking `refcount_read == 1`. Fixed `evlist__purge` recursion and cycle reference tearing logic.
v2:
1. Fixed Memory Leak in evlist__new : Added free(evlist) in the else
branch if ADD_RC_CHK fails, preventing a leak of the allocated raw
structure.
2. Fixed Potential NULL Dereference: Added a NULL check after
from_list_start(_evlist) in perf_evlist__mmap_cb_get() .
3. Fixed Use-After-Free Risk: In evlist__add() , I changed
entry->evlist = evlist; to entry->evlist = evlist__get(evlist);
. This ensures that the evsel holds a valid reference (wrapper) to
the evlist , preventing it from becoming a dangling pointer if the
original wrapper is freed.
4. Fixed Test Masking Bug: In test__perf_time__parse_for_ranges() , I
replaced TEST_ASSERT_VAL with a manual check and return false; to
avoid boolean evaluation of -1 inadvertently passing the test.
5. Fix reference count checker memory leaks from missed puts and due
to cyclic evsel to evlist references. A leak still exists in
__perf_evlist__propagate_maps due to empty CPU maps and not
deleting the removed evsel.
v8:
1. Handle evsel__new failure in sample-parsing.c test and extra ref
count checking integrity in evlist.c
2. Use standard per_sample initialization in cs-etm.c.
v10:
- Added CHECK_INITIALIZED checks to pyrf_evlist methods to prevent
NULL pointer dereferences on uninitialized objects.

* [PATCH v17 06/20] perf evsel: Add reference count
From: Ian Rogers @ 2026-06-13 7:10 UTC (permalink / raw)
To: irogers, acme, namhyung
Cc: adrian.hunter, alice.mei.rogers, dapeng1.mi, james.clark, leo.yan,
linux-kernel, linux-perf-users, mingo, peterz, tmricht
In-Reply-To: <20260613071100.1508192-1-irogers@google.com>
As with evlist this a no-op for most of the perf tool. The reference
count is set to 1 at allocation, the put will see the 1, decrement it
and perform the delete. The purpose for adding the reference count is
for the python code. Prior to this change the python code would clone
evsels, but this has issues if events are opened, etc. leading to
assertion failures. With a reference count the same evsel can be used
and the reference count incremented for the python usage. To not
change the python evsel API getset functions are added for the evsel
members, no set function is provided for size as it doesn't make sense
to alter this.

v12:
- Restored `idx` parsing in `pyrf_evsel__init` kwargs, and removed an erroneous `Py_INCREF(pevsel)` in `pyrf_evlist__add` that caused a memory leak.
v2:
1. Fixed Potential Crash in pyrf_event__new : Initialized
pevent->evsel = NULL; to avoid garbage pointer dereference if
evlist__event2evsel() fails in read_on_cpu .
2. Fixed Memory Leak in pyrf_evsel__init : Added
evsel__put(pevsel->evsel) before overwriting it to handle repeated
__init__ calls.
3. Fixed Exception Contract: Added PyErr_NoMemory() when evsel__new()
fails in pyrf_evsel__init .
4. Fixed NULL Pointer Dereference on Property Access: Added a custom
tp_getattro ( pyrf_evsel__getattro ) to pyrf_evsel__type to check
if pevsel->evsel is NULL and raise a ValueError if so, covering all
property accesses.
5. Fixed Reference Count in pyrf_evlist__add : Added evsel__get(evsel)
when adding to the evlist .
6. Fixed Reference Count in pyrf_evlist__read_on_cpu : Added
evsel__get(evsel) when assigning to pevent->evsel .
v7:
- Added pyrf_evsel__new to zero-initialize pevsel->evsel to fix
crash on re-initialization.
v8:
- Added O! type validation to pyrf_evlist__add to prevent type
confusion.
v10:
- Added strict CHECK_INITIALIZED/CHECK_INITIALIZED_INT checks to all
pyrf_evsel methods and property getters/setters to prevent NULL
pointer dereferences if the object is instantiated without calling
__init__.
