Subject: [PATCH v6 00/27] Constify tool pointers
Date: Wed, 17 Jul 2024 17:59:56 -0700	[thread overview]
Message-ID: <20240718010023.1495687-1-irogers@google.com> (raw)

struct perf_tool provides a set of function pointers that are called
through when processing perf data. To make filling the pointers less
cumbersome, if they are NULL perf_tools__fill_defaults will add
default do nothing implementations.

This change refactors struct perf_tool to have an init function that
provides the default implementation. The special use of NULL and
perf_tools__fill_defaults are removed. As a consequence the tool
pointers can then all be made const, which better reflects the
behavior a particular perf command would expect of the tool and to
some extent can reduce the cognitive load on someone working on a
command.

v6: Rebase adding Adrian's reviewed-by/tested-by and Leo's tested-by.
v5: Rebase dropping asan fix merged by Namhyung.
v4: Simplify perf_session__deliver_synth_attr_event following Adrian's
    suggestions.
v3: Just remove auxtrace dummy tools [Adrian] and make s390-cpumsf
    struct removal its own patch [Adrian].
v2: Remove dummy tool initialization [Adrian] and make zero sized. Add
    cs-etm fix for address sanitizer build, found necessary when
    testing dummy tool change.

Ian Rogers (27):
  perf auxtrace: Remove dummy tools
  perf s390-cpumsf: Remove unused struct
  perf tool: Constify tool pointers
  perf tool: Move fill defaults into tool.c
  perf tool: Add perf_tool__init
