Is this a problem? This removes clutter from the output, right?

Dunno, you made an output that looked like a pointer address,

64 bit:

"0x0123456789abcdef" now is " 123456789abcdef"

32 bit:

"0x0000000001234567" now is " 1234567"

snprintf(loc, size, "%#0*lx", BITS_PER_LONG / 4 + 2, (long))
might be better.

snprintf(loc, size, "%p", (void)long)
might be best.

Oops.

On the other hand, "%p", (void *) would compile
without warnings and be what I meant in the first
place...

snprintf(loc, size, "%p", (void *)long)

[PATCH 06/10] perf ui: Add search by name/addr to the map__browser

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Only in verbose mode so as not to bloat struct symbol too much.

The key used is '/', just like in vi, less, etc.

More work is needed to allocate space on the symbol in a more clear way.

This experiment shows how to do it for the hist_browser, in the main
window.

[PATCH 10/10] perf report: Speed up exit path

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

When cmd_record exits the whole perf binary will exit right after,
so no need to traverse lots of complex data structures freeing them.

Sticked a comment for leak detectives and for a experiment with obstacks
to be performed so that we can speed up freeing that memory.

  perf trace: Tell arg formatters the arg index (2013-09-02 16:40:40 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

. 'perf trace' arg formatting improvements to allow masking arguments
  in syscalls such as futex and open, where the some arguments are
  ignored and thus should not be printed depending on other args.

. Beautify futex open, openat, open_by_handle_at, lseek and futex syscalls.

. Add dummy software event to use when wanting just to keep receiving
  PERF_RECORD_{MMAP,COMM,etc}, add test for it, from Adrian Hunter.

. Fix symbol offset computation for some dsos in 'perf script', from David Ahern.

. Skip unsupported hardware events in 'perf list', from Namhyung Kim.

So a bit of background: sloppy, abusive contributors not willing to 
change get ignored after some time. For example Andi got such a bad 
track record in the x86 and perf space with me that all your mails go 
to /dev/null currently. (I only saw this one because Namhyung replied 
to it.)

Andi, as I explained it to you previously, if you want me to merge 
patches from you then you need to 1) improve the way you work 2) send 
it to someone who is willing to deal with you and sign off on it and 
forward it to me.

Seems like you managed to burn up your goodwill with Arnaldo as well. 
You need to find someone else willing to pay the expense of dealing 
with your passive-aggressive style.

Just a quick example of your abuse: for example you know it perfectly 
well that perf is well maintained, a simple 'git log tools/perf/' will 
tell you that there's a steady stream of patches going in and that 
perf contributors are busy.

Yet in this mail you actually lie about that: you pretend that you 
don't know that most Linux maintainers have trouble working with you, 
you pretend that perf is "unmaintained", you pretend that you don't 
know who is maintaining it, just to create unfair pressure on Arnaldo 
...

That kind of approach really sucks, and if you run out of people's 
patience with petty office tactics like that then you should not fault

  perf symbols: Convert lseek + read to pread (2015-01-29 17:02:01 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Show precise number of samples in at the end of a 'record' session, if
  processing build ids, since we will then traverse the whole perf.data file
  and see all the PERF_RECORD_SAMPLE records, otherwise stop showing the
  previous off-base heuristicly counted number of "samples"  (Namhyung Kim).

- Support to read compressed module from build-id cache (Namhyung Kim)

Infrastructure:

- Cache eh/debug frame offset for dwarf unwind (Namhyung Kim)

- Set header version correctly in all cases (Namhyung Kim)

- Set attr.task bit for a tracking event, to be consistent (Namhyung Kim)
  perf tools: Use perf_data_file__fd() consistently
  perf symbols: Convert lseek + read to pread

- Don't rely on malloc working for sz 0, fixing another problem when
  using uClibc (Vineet Gupta)

- Provide stub for missing pthread_attr_setaffinity_np for libcs where this
  is not available, such as uClibc (Vineet Gupta)

Hm, your pull request mail was cut short as it ends here abruptly. I figured it 
out nevertheless, from the commit log:

====================>

User visible changes:

  - Force period term to overload global settings, i.e. previously this
    command line:

     $ perf record -e 'cpu/instructions,period=20000/',cycles -c 1000 sleep 1

    would result in both events having a period equal to 1000, with the fix we
    get something saner:

     $ perf evlist -v | grep period
     cpu/instructions,period=20000/: ... { sample_period, sample_freq }: 20000, ...
     cycles: ... { sample_period, sample_freq }: 1000 ...
     $

   (Jiri Olsa)

Infrastructure changes:

  - Use the dummy software event with freq=0 in the twatch.py python
    binding example, to avoid disabling nohz. (Arnaldo Carvalho de Melo)

  - Add some missing constants to the python binding. (Arnaldo Carvalho de Melo)

  - Fix mismatched declarations for elf_getphdrnum, that happens
    only in the corner case where this function is not found on
    the system.  (Arnaldo Carvalho de Melo)

  - Add build test for having ending double slash. (Jiri Olsa)

  - Introduce callgraph_set for callgraph option. (Kan Liang)

Pulled, thanks a lot Arnaldo!

Should any of the above fixes be cherry-picked over into perf/urgent, or are these 
all new regressions?

At least my changes should go into perf/urgent and probably stable too.

[GIT PULL 00/10] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling,

- Arnaldo

The following changes since commit fe7a2eaa71c55aadbf95d01d32df8dccc0db0646:

  Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2016-02-16 08:45:56 +0100)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo

for you to fetch changes up to cb110f471025f3278978aaccb18f3164ea2b8189:

  perf stat: Move noise/running printing into printout (2016-02-16 17:13:02 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Make 'perf record' collect CPU cache info in the perf.data file header:

  $ perf record usleep 1
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.017 MB perf.data (7 samples) ]
  $ perf report --header-only -I | tail -10 | head -8
  # CPU cache info:
  #  L1 Data                 32K [0-1]
  #  L1 Instruction          32K [0-1]
  #  L1 Data                 32K [2-3]
  #  L1 Instruction          32K [2-3]
  #  L2 Unified             256K [0-1]
  #  L2 Unified             256K [2-3]
  #  L3 Unified            4096K [0-3]
  $

  Will be used in 'perf c2c' and eventually in 'perf diff' to allow, for instance
  running the same workload in multiple machines and then when using 'diff' show
  the hardware difference. (Jiri Olsa)

- 'perf stat' now shows shadow metrics (insn per cycle, etc) in
  interval mode too. E.g:

    # perf stat -I 1000 -e instructions,cycles sleep 1
    #         time   counts unit events
       1.000215928  519,620      instructions     #  0.69 insn per cycle
       1.000215928  752,003      cycles
    <SNIP>

Infrastructure:

- libapi now can also use pr_{warning,info,debug}() and that can be
  set by tools using it (Jiri Olsa)

- libapi adopts filename__read_str() from perf, adds sysfs__read_str() (Jiri Olsa)

- Add check for java alternatives cmd in jvmti Makefile, so that it manages
  to automatically find the right path for the JDK devel files in Ubuntu like
  systems in addition to Fedora like ones (Stephane Eranian)

  perf bpf: Add sample types for 'bpf-output' event (2016-04-01 18:46:25 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Do not use events that don't have timestamps when setting 'perf trace's
  base timestamp, fixing up the timestamp column for syscalls (Arnaldo Carvalho de Melo)

[GIT PULL 00/10] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

Hi Ingo,

The following changes since commit 275ae411e56f8f900fa364da29c4706f9af4e1f3:

  perf/x86/intel/rapl: Fix pmus free during cleanup (2016-05-25 10:56:43 +0200)

  tools: Pass arg to fdarray__filter's call back function (2016-05-25 17:27:25 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible/kernel ABI:

- Per event callchain limit: Recently we introduced a sysctl to tune the
  max-stack for all events for which callchains were requested:

  $ sysctl kernel.perf_event_max_stack
  kernel.perf_event_max_stack = 127

  Now this patch introduces a way to configure this per event, i.e. this
  becomes possible:

  $ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a

  allowing finer tuning of how much buffer space callchains use.

  This uses an u16 from the reserved space at the end, leaving another
  u16 for future use.

  There has been interest in even finer tuning, namely to control the
  max stack for kernel and userspace callchains separately. Further
  discussion is needed, we may for instance use the remaining u16 for
  that and when it is present, assume that the sample_max_stack introduced
  in this patch applies for the kernel, and the u16 left is used for
  limiting the userspace callchain. (Arnaldo Carvalho de Melo)

Pretty much. Two similar solutions were developed around the same
time. Although I have to use some awk to get "perf -g folded" in the
exact right format, and stackcollapse-perf.py does that directly.

Yes, the idea for stackcollapse-perf.py was:

- to do everything directly and emit "the right" format for the
flamegraph tools.  This however is a very minimal output, and it's not
necessarily the best for perf in general.

- to provide an example of visiting callgraphs from the scripting
interface, since it's not really documented.  From the commit message:
"Add stackcollapse.py script as an example of parsing call chains, and
also of using optparse to access command line options".

Yeah, agreed, its short, and it provides the output ready to be used, no
need for extra processing, up to the user to decide if one or the other
is more suitable to their needs.

As a bonus, it documents callgraphs in scripts, good deal :-)

perf/core improvements and fixes:

Improvements:

- Improve error message when analyzing file with required events in
  'perf sched timehist' (David Ahern)

Fixes:

- Force fixdep compilation to be done at the start of the build, fixing
  some build race conditions in high core count machines (Jiri Olsa)

- Fix handling a zero sample->tid in 'perf sched timehist', as
  sometimes that isn't the idle thread (Namhyung Kim)

Infrastructure:

- Check minimal accepted LLVM version in its feature check, 3.9 at this
  time (Wang Nan)

Documentation:

- Explicitly document that --children is enabled by default (Yannick Brosseau)

[GIT PULL 00/10] perf/core improvements and fixes

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Hi Ingo,

	Please consider pulling,

Test results at the end of this message, as usual.

The following changes since commit 5b485629ba0d5d027880769ff467c587b24b4bde:

  kprobes, extable: Identify kprobes trampolines as kernel text area (2017-01-14 08:38:05 +0100)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-4.11-20170117

for you to fetch changes up to d94386f28abad0c5879f0760712e34e71f88a7da:

  perf evlist: Fix typo in deliver_sample() (2017-01-17 11:36:45 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

New feature:

- Account thread wait time (off cpu time) separately: sleep, iowait and
  preempt, based on the prev_state of the last event, show the breakdown
  when using "perf sched timehist --state" (Namhyumg Kim)

Infrastructure:

- Factor out pmu scale conversion code (Andi Kleen)

- Remove unnecessary feature-dwarf warning (David Carrillo-Cisneros)

- Add missing member name in OPT_() macros (Soramichi AKIYAMA)

- Move variables referenced in libperf.a object files from perf's main()
  file, so that other tools can use libperf.a with a different main()
  (Soramichi AKIYAMA)

Documentation:

- Fix 'perf script' man page about --dump-raw-trace option (Michael Petlan)

- Also allow forcing reading of non-root owned files by root in 'perf
  script' (Yannick Brosseau)

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.

Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

  perf config: Refactor a duplicated code for obtaining config file name (2017-05-02 18:23:12 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

Fixes:

- Support setting probes in versioned user space symbols, such as
  pthread_create@@GLIBC_2.1, picking the default one, more work
  needed to make it possible to set it on the other versions, as
  the 'perf probe' syntax already uses @ for other purposes.
  (Paul Clarke)

- Do not special case address zero as an error for routines that
  return addresses (symbol lookup), instead use the return as the
  success/error indication and pass a pointer to return the address,
  fixing 'perf test vmlinux' (the one that compares address between
  vmlinux and kallsyms) on s/390, where the '_text' address is equal
  to zero (Arnaldo Carvalho de Melo)

Infrastructure:

- More header sanitization, moving stuff out of util.h into
  more appropriate headers and objects and sometimes creating
  new ones (Arnaldo Carvalho de Melo)

- Refactor a duplicated code for obtaining config file name (Taeung Song)

Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

----------------------------------------------------------------
Arnaldo Carvalho de Melo (8):
      perf buildid: Move prototypes from util.h to build-id.h
      perf tools: Move event prototypes from util.h to event.h
      perf memswap: Split the byteswap memory range wrappers from util.[ch]
      perf tools: Move HAS_BOOL define to where perl headers are used
      perf ui gtk: Move gtk .so name to the only place where it is used
      perf units: Move parse_tag_value() to units.[ch]
      tools lib string: Adopt prefixcmp() from perf and subcmd
      perf symbols: Accept symbols starting at address 0

Paul Clarke (1):
      perf symbols: Allow user probes on versioned symbols

Taeung Song (1):
      perf config: Refactor a duplicated code for obtaining config file name

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.

Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

  perf test shell: Replace '|&' with '2>&1 |' to work with more shells (2017-08-16 16:23:26 -0300)

----------------------------------------------------------------
perf core improvements and fixes:

New features:

- Support exporting Intel PT data to sqlite3 with python perf scripts,
  this is in addition to the postgresql support that was already there (Adrian Hunter)

Infrastructure:

- Handle perf tool builds with less features in perf shell tests, such
  as those with NO_LIBDWARF=1 or even without 'perf probe' (Arnaldo Carvalho de Melo)

- Replace '|&' with '2>&1 |' to work with more shells in the just
  introduced perf test shell harness (Kim Phillips)

Architecture related fixes:

- Fix endianness problem when loading parameters in the BPF prologue
  generated by perf, noticed using 'perf test BPF' in s390x systems (Wang Nan, Thomas Richter)

Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

----------------------------------------------------------------
Adrian Hunter (5):
      perf scripts python: Fix missing call_path_id in export-to-postgresql script
      perf scripts python: Fix query in call-graph-from-postgresql.py
      perf script python: Add support for exporting to sqlite3
      perf script python: Rename call-graph-from-postgresql.py to call-graph-from-sql.py
      perf script python: Add support for sqlite3 to call-graph-from-sql.py

Arnaldo Carvalho de Melo (3):
      perf tests shell: Remove duplicate skip_if_no_debuginfo() function
      perf test shell: Check if 'perf probe' is available, skip tests if not
      perf test shell vfs_getname: Skip for tools built with NO_LIBDWARF=1

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.

Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf
commands with a variety of command line event specifications to then
intercept the sys_perf_event syscall to check that the perf_event_attr
fields are set up as expected, among a variety of other unit tests.

The 'perf test'  also runs shell scripts exercising the tools, checking
if they affect the system in certain ways, like setting up kprobes and
uprobes, request callchains for well known programs and check that they
are the expected ones, see if 'perf trace' beautifies system call
arguments correctly, etc.

Additionally, a new set of tests, script based, runs the tools in a live system,
setting probes in place that then gets used by 'perf trace', with its output
compared against expected results.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
