[PATCH v8 53/58] perf: Remove libperl support, legacy Perl scripts and tests

Ian Rogers
2026-04-28T07:21:05Z

Remove libperl support from perf, along with legacy Perl scripts
and their corresponding tests.

Assisted-by: Gemini:gemini-3.1-pro-preview
Signed-off-by: Ian Rogers <irogers@google.com>
---
v5:
1. Fix Buffer Overflows: Added bounds checks in `check_ev_match()` and
`find_scripts()` to prevent stack and heap buffer overflows when
parsing long event or script names.

-Perf-Trace-Util version 0.01
-============================
-
-This module contains utility functions for use with perf script.
-
-Core.pm and Util.pm are pure Perl modules; Core.pm contains routines
-that the core perf support for Perl calls on and should always be
-'used', while Util.pm contains useful but optional utility functions
-that scripts may want to use. Context.pm contains the Perl->C
-interface that allows scripts to access data in the embedding perf
-executable; scripts wishing to do that should 'use Context.pm'.
-
-The Perl->C perf interface is completely driven by Context.xs. If you
-want to add new Perl functions that end up accessing C data in the
-perf executable, you add desciptions of the new functions here.
-scripting_context is a pointer to the perf data in the perf executable
-that you want to access - it's passed as the second parameter,
-$context, to all handler functions.
-
-After you do that:
-
- perl Makefile.PL # to create a Makefile for the next step
- make # to create Context.c
-
- edit Context.c to add const to the char* file = __FILE__ line in
- XS(boot_Perf__Trace__Context) to silence a warning/error.
-
- You can delete the Makefile, object files and anything else that was
- generated e.g. blib and shared library, etc, except for of course
- Context.c
-
- You should then be able to run the normal perf make as usual.
-
-INSTALLATION
-
-Building perf with perf script Perl scripting should install this
-module in the right place.
-
-You should make sure libperl and ExtUtils/Embed.pm are installed first
-e.g. apt-get install libperl-dev or yum install perl-ExtUtils-Embed.
-
-DEPENDENCIES
-
-This module requires these other modules and libraries:
-
- None
