Subject: [PATCH v4 00/49] perf: Complete transition to standalone Python scripts
From: Ian Rogers <irogers@google.com>
To: irogers@google.com, acme@kernel.org, alice.mei.rogers@gmail.com,

The perf script command has historically supported running Python and Perl
scripts by embedding libpython and libperl. That approach has several
drawbacks:
 - high overhead from constructing Python dictionaries for every event
   (whether used by the script or not),
 - complex build dependencies on specific Python/Perl libraries,
 - threading and interpreter lifecycle complications from embedding the
   interpreter inside perf,
 - no unified model for standalone scripts such as ilist.py, treport.py,
   tracepoint.py, and twatch.py.

Parts of this series were previously posted as part of the larger
"perf: Reorganize scripting support" series:
https://lore.kernel.org/linux-perf-users/20260428071903.1886173-1-irogers@google.com/
with earlier RFC and mailing list discussion at:
https://lore.kernel.org/linux-perf-users/20251029053413.355154-1-irogers@google.com/
https://lore.kernel.org/lkml/CAP-5=fWDqE8SYfOLZkg_0=4Ayx6E7O+h7uUp4NDeCFkiN4b7-w@mail.gmail.com/

>From that earlier series, the prerequisite patches (header dependency
cleanups, evlist/evsel reference counting, initial perf.data and
perf.session C extension wrappers, callchain/brstack/stat/syscall/config
accessors, perf.pyi type stubs, LiveSession, and removal of embedded
libperl support) have now been merged. We restarted the version number at
v1 for the remaining patches, along with additional C extension
capabilities, build-time static analysis (mypy and pylint), and review
fixes.

Running scripts as standalone Python applications using the perf Python C
extension module provides a dramatic speedup. For example, with
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
```

The 49 patches in this series are organized into four groups:

1. Perf Python C Extension & Existing Script Updates (Patches 01-10):
   - Refine syscall_name()/syscall_id() argument parsing, expose
     perf.arch_strerrno() from the auto-generated trace beauty errno tables,
     and update callchain stubs and session.find_thread() lookup in
     tools/perf/util/python.c and tools/perf/python/perf.pyi.
   - Clean up pylint warnings and improve `perf script -l` descriptions in
     existing standalone scripts (ilist.py, treport.py, tracepoint.py,
     twatch.py).
   - Expose destination address location attributes (addr_dso, addr_symbol,
     addr_sym_offset), branch/transaction fields, sym_offset, context_switch
     callbacks, and Intel PT call_return / itrace synthesis directly in the
     perf Python extension (many parts previously posted in
     https://lore.kernel.org/linux-perf-users/20260428071903.1886173-1-irogers@google.com/).
   - Allow KeyboardInterrupt to propagate cleanly in LiveSession.

2. Build-Time Python Static Analysis (Patches 11-14):
   - Clean up mypy and pylint warnings in tools/perf/pmu-events/ and
     tools/perf/tests/shell/lib/.
   - Make MYPY and PYLINT build checks enabled by default when mypy and
     pylint (>= 2.16.0) are installed, with NO_MYPY=1 and NO_PYLINT=1 opt-out
     controls (matching NO_SHELLCHECK=1), so all Python scripts in tools/perf
     are continuously type-checked and linted at build time.

3. Porting Legacy Python & Perl Scripts to tools/perf/python/ (Patches 15-45):
   - Previously sent as part of
     https://lore.kernel.org/linux-perf-users/20260428071903.1886173-1-irogers@google.com/
     and updated with static type annotations, mypy/pylint cleanups, and
     accompanying shell tests under tools/perf/tests/shell/. Sashiko-driven
     review and improvement was undertaken while porting so that the ported
     scripts are in the best shape possible:
     * Temporarily install tools/perf/python/ scripts during the transition
       (Patch 15).
     * General & profiling scripts: stat-cpi.py, mem-phys-addr.py,
       stackcollapse.py, flamegraph.py, gecko.py, event_analyzing_sample.py
       (Patches 16-21).
     * Syscall & I/O scripts (ported from legacy Python and Perl):
       syscall-counts.py, syscall-counts-by-pid.py,
       failed-syscalls-by-pid.py, failed-syscalls.py, sctop.py, rw-by-file.py,
       rw-by-pid.py, rwtop.py (Patches 22-29).
     * Scheduling, locking, MM & networking scripts: futex-contention.py,
       task-analyzer.py, sched-migration.py (with SchedGui.py),
       wakeup-latency.py, compaction-times.py, net_dropmonitor.py,
       netdev-times.py, check-perf-trace.py (Patches 30-37).
     * Hardware trace & architecture-specific scripts: arm-cs-trace-disasm.py,
       powerpc-hcalls.py, intel-pt-events.py (with libxed.py), and migrating
       the Intel PT virtual LBR test to the Python API (Patches 38-41).
     * Database export & viewer utilities: export-to-sqlite.py,
       export-to-postgresql.py, exported-sql-viewer.py, and parallel-perf.py
       (Patches 42-45).

4. Removing Embedded libpython & Updating Build, CLI, and Docs (Patches 46-49):
   - Previously sent as part of
     https://lore.kernel.org/linux-perf-users/20260428071903.1886173-1-irogers@google.com/ :
     * Remove embedded libpython support (scripting-engines/trace-event-python.c)
       and delete the legacy tools/perf/scripts/python/ directory (Patch 46).
     * Replace the libpython feature check with test-python-module.c and
       update Python script installation paths (Patch 47).
     * Update `perf script` (builtin-script.c) to execute standalone scripts
       directly and remove embedded scripting engine support (Patch 48).
     * Update perf man pages (perf-script.txt, perf-script-python.txt,
       perf-check.txt) for standalone Python scripts (Patch 49).

Changes in v4:
 - Rebase onto latest `perf-tools-next`, explicitly `#include <stdint.h>` for
   `UINT16_MAX` in `tools/perf/util/python.c`, and ensure `Event.ToPerfJson()`
   in `tools/perf/pmu-events/metric.py` and `IntelFpu()` in `intel_metrics.py`
   escape event modifier `=` and `,` characters (Patches 01, 11).
 - Set `symbol_conf.{vmlinux_name,kallsyms_name,symfs}` before calling
   `perf_session__new()` in `pyrf_session__init()` so `--kcore` directory loads
   in `perf_session__new()` do not overwrite a user-specified `vmlinux_name`,
   unconditionally attach `session->itrace_synth_opts` to `perf.session`, and
   honor `PERF_ITRACE` in `perf.session`, `arm-cs-trace-disasm.py`,
   `intel-pt-events.py`, and `perf script --itrace=... <script>` (Patches 09,
   38, 40, 48, 49).
 - Match exact base event names (`cycles` / `cpu-cycles` and `instructions`) in
   `stat-cpi.py` instead of substring matching so events such as `bus-cycles` or
   `branch-instructions` do not corrupt CPI totals, and validate file-mode and
   pipe-mode JSON outputs independently in `test_flamegraph_python.sh` (Patches
   16, 19, 48).
 - Distinguish per-syscall `syscalls:sys_enter_*` tracepoints (prefix
   `evsel(syscalls:sys_enter_`, which expose `__syscall_nr` or `nr`) from
   `raw_syscalls:sys_enter` and legacy `syscalls:sys_enter` tracepoints (which
   expose `id`) in `syscall-counts.py`, `syscall-counts-by-pid.py`, and
   `sctop.py`, and guard `sample_time` interval checks in `rwtop.py` when
   `sample_time` is zero or absent (Patches 22, 23, 26, 29).
 - In `arm-cs-trace-disasm.py`, initialize `cpu_data` with the initial sample's
   `sample_addr` before filtering `dso == '[unknown]'` (preserving the behavior
   of commit 2d98dbb4c9c5 ("perf scripts python arm-cs-trace-disasm.py: Do not ignore disam first sample")
   on initial `CS_ETM_TRACE_ON` samples with `ip == 0`), restore the original
   script's usage and packet diagram comments, and remove the redundant
   `--itrace=b` argument in `test_arm_coresight_disasm.sh` since
   `arm-cs-trace-disasm.py` defaults to `itrace="b"` (Patch 38, reported by Leo
   Yan).
 - In `builtin-script.c`, wait on the standalone script child process with
   `waitid(..., WEXITED | WNOWAIT)` before clearing `script_child_pid` and
   restoring signal handlers, then reap with `waitpid()`, preventing a PID-reuse
   race window in `forward_script_sig()` (Patch 48).

Changes in v3:
 - Expose `perf_env__arch_strerrno()` as `perf.arch_strerrno()` in
   `tools/perf/util/python.c` (and tighten `arch_errno_names.sh` macro matching
   to `E[A-Z0-9]+` with `EM_SPARC32PLUS` support) so `failed-syscalls-by-pid.py`
   uses the auto-generated C beauty errno tables instead of maintaining Python
   errno dictionaries (Patches 01, 24).
 - Change `static char * const kwlist[]` to `static char *kwlist[]` in
   `pyrf_session__new()` in `tools/perf/util/python.c` to support Python < 3.13
   where `PyArg_ParseTupleAndKeywords()` expects `char **` rather than
   `char *const *`, and register `psession->tool.event_update` so pipe-mode
   `PERF_RECORD_EVENT_UPDATE` metadata is processed (Patches 08, 09).
 - Explicitly annotate `d_hcoal: Union[Event, int]` and
   `d_mcoal: Union[Event, int]` in `AmdDtlb()` in
   `tools/perf/pmu-events/amd_metrics.py` so older `mypy` versions do not infer
   `join(Event, int) = object` (Patch 11).
 - Pass `--ignore-missing-imports` to `MYPY` and
   `--ignored-modules=textual,setproctitle` to `PYLINT` in
   `tools/perf/Makefile.perf` so default static analysis builds succeed on
   systems without optional third-party Python packages (`python3-textual`,
   `python3-setproctitle`) installed (Patches 13, 14).
 - Chain `$(INSTALL)` commands with `&&` in `Makefile.perf` for the
   `python-scripts` installation rules and invoke `"perf script "` without `-s`
   from `script_browse()` in `ui/browsers/scripts.c` (Patches 15, 47).
 - Add Subresource Integrity (`integrity="sha256-..."`) attributes to the CDN
   `<link>` and `<script>` tags in `MINIMAL_HTML` in `flamegraph.py`
   (Patch 19).
 - Remove obsolete `AttributeError` fallback in `gecko.py` and ensure SQLite
   connections in `event_analyzing_sample.py` are closed on error in
   `trace_begin()` and `trace_end()` (Patches 20, 21).
 - Continue updating timeslices in `sched_switch()` in `sched-migration.py`
   after printing a rejection warning so runqueue state resynchronizes after
   dropped ring-buffer events (Patch 32).
 - Check `if not irq_list` in `handle_irq_softirq_exit()` in `netdev-times.py`
   so empty `irq_list` entries do not append vacuous hunks (Patch 36).
 - Move `setup_python.sh` path resolution updates to Patch 12, encapsulate
   `cpu_data` on `TraceDisasm` and honor `PERF_SYMBOL_VMLINUX` in
   `arm-cs-trace-disasm.py`, and add `Reviewed-by: James Clark
   <james.clark@linaro.org>` (Patches 12, 38).
 - Fix unpacked `cbr` payload variable names (`cbr_val, max_nonturbo, freq`) in
   `export-to-sqlite.py` and `export-to-postgresql.py`, and catch
   `BaseException` before terminating worker processes and re-raising in
   `parallel-perf.py` (Patches 42, 43, 45).
 - Improve shell test robustness in `test_stat_cpi_python.sh`,
   `test_task_analyzer.sh`, `test_compaction_times_python.sh`,
   `test_net_dropmonitor_python.sh`, and `test_arm_coresight_disasm.sh`, and
   update all Python script shell tests to invoke `perf script <script>` in
   Patch 48 (Patches 16, 31, 34, 35, 38, 48).

Changes in v2:
 - Mark `session.find_thread()` parameters as positional-only (`/`) and update
   `sample_event.srccode()` return type annotation to
   `Optional[tuple[Optional[str], int, Optional[str]]]` in `perf.pyi` (Patches
   02, 08).
 - Break `self -> self.session -> bound method callback` reference cycles in
   `flamegraph.py`, `failed-syscalls.py`, `wakeup-latency.py`, and
   `arm-cs-trace-disasm.py` via `try ... finally: self.session = None` (Patches
   19, 25, 33, 38).
 - Separate `raw_syscalls:sys_enter` (`id`) from `syscalls:sys_enter*`
   (`__syscall_nr` / `nr`) and support x32 ABI syscall numbers (`0x40000000`)
   in `syscall-counts.py`, `syscall-counts-by-pid.py`, and `sctop.py` (Patches
   22, 23, 26).
 - Prevent non-generic architectures in `_ARCH_ERRNO_TABLES` from falling
   through into `_GENERIC_ERRNO_OVERRIDES` in `failed-syscalls-by-pid.py`
   (Patch 24).
 - Treat 0-byte read/write return values as non-errors in `rw-by-pid.py`
   (Patch 28).
 - Avoid repeated `/proc/kallsyms` parsing and cache fallback symbol
   resolutions in `net_dropmonitor.py` (Patch 35).
 - Check `is None` instead of truthiness for `event_list` in `netdev-times.py`
   so valid softirqs with empty event lists are not dropped (Patch 36).
 - Handle `objdump` subprocess errors gracefully in `arm-cs-trace-disasm.py`
   and update `setup_python.sh` / `test_arm_coresight_disasm.sh` so nested
   shell tests locate `perf.so` when run directly (Patches 12, 38).
 - Populate `branch_types`, `samples_view.branch_type_name`, `calls` parent
   indexes (`pcpid_idx`, `pid_idx`), and `comms.has_calls` in
   `export-to-sqlite.py` for `exported-sql-viewer.py` compatibility (Patch 42).
 - Escape single quotes with `\'` for libpq connection strings in
   `export-to-postgresql.py` (Patch 43).
 - Replace Markdown `###` subsection headers with Asciidoc `~~~~` underlines in
   `perf-script-python.txt` (Patch 49).
