perf util: Add a function for replacing characters in a string

2024-06-12T09:13:02+00:00

commit 8a55c1e2c9e123b399b272a7db23f09dbb74af21 upstream. It finds all occurrences of a single character and replaces them with a multi character string. This will be used in a test in a following commit.

perf tools: Add OCaml demangling

2021-02-17T18:15:06+00:00

Detect symbols generated by the OCaml compiler based on their prefix. Demangle OCaml symbols, returning a newly allocated string (like the existing Java demangling functionality). Move a helper function (hex) from tests/code-reading.c to util/string.c To test: echo 'Printf.printf "%d\n" (Random.int 42)' > test.ml perf record ocamlopt.opt test.ml perf report -d ocamlopt.opt Signed-off-by: Fabian Hemmer Acked-by: Namhyung Kim Cc: Alexander Shishkin Cc: Jiri Olsa Cc: Mark Rutland Cc: Peter Zijlstra LPU-Reference: 20210203211537.b25ytjb6dq5jfbwx@nyu Signed-off-by: Arnaldo Carvalho de Melo

perf string: Export asprintf__tp_filter_pids()

2019-10-15T16:03:57+00:00

Will be used directly in 'perf trace' for setting up the command line argv array to pass to cmd_record, as this was how 'perf trace record' was implemented, following the model used in 'perf kvm record', 'perf sched record', etc. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Luis Cláudio Gonçalves Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-w3cuwjs63lxf5zpryy3145uv@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

tools lib: Move argv_{split,free} from tools/perf/util/

2019-07-02T01:50:40+00:00

This came from the kernel lib/argv_split.c, so move it to tools/lib/argv_split.c, to get it closer to the kernel structure. We need to audit the usage of argv_split() to figure out if it is really necessary to do have one allocation per argv[] entry, looking at one of its users I guess that is not the case and we probably are even leaking those allocations by not using argv_free() judiciously, for later. With this we further remove stuff from tools/perf/util/, reducing the perf specific codebase and encouraging other tools/ code to use these routines so as to keep the style and constructs used with the kernel.

perf tools: Drop strxfrchar(), use strreplace() equivalent from kernel

2019-07-02T01:50:40+00:00

No change in behaviour intended, just reducing the codebase and using something available in tools/lib/. Cc: Adrian Hunter Cc: Jiri Olsa Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-oyi6zif3810nwi4uu85odnhv@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Ditch rtrim(), use strim() from tools/lib

Cleaning up a bit more tools/perf/util/ by using things we got from the kernel and have in tools/lib/ Cc: Adrian Hunter Cc: Jiri Olsa Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-7hluuoveryoicvkclshzjf1k@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Remove trim() implementation, use tools/lib's strim()

No change in behaviour, just using the same kernel idiom for such operation. Cc: Adrian Hunter Cc: André Goddard Rosa Cc: Jiri Olsa Cc: Namhyung Kim Link: https://lkml.kernel.org/n/tip-a85lkptkt0ru40irpga8yf54@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf string: Move 'dots' and 'graph_dotted_line' out of sane_ctype.h

2019-06-25T20:31:26+00:00

Those are not in that file in the git repo, lets move it from there so that we get that sane ctype code fully isolated to allow getting it in sync either with the git sources or better with the kernel sources (include/linux/ctype.h + lib/ctype.h), that way we can use check_headers.h to get notified when changes are made in the original code so that we can cherry-pick.
