perf script has a setting to set the maximum stack depth when processing
callchains. The setting defaults to the hard-coded maximum definition
PERF_MAX_STACK_DEPTH which is 127.
It is possible, when processing instruction traces, to synthesize
callchains. Synthesized callchains do not have the kernel size
limitation and are whatever size the user requests, although validation
presently prevents the user requested a value greater that 1024. The
default value is 16.
To allow for synthesized callchains, make the scripting_max_stack value
at least the same size as the synthesized callchain size.

In a couple of cases the 'comm' member of 'union event' has been used
instead of the correct member ('fork') when processing exit events.
In the cases where it has been used incorrectly, only the 'pid' and
'tid' are affected. The 'pid' value would be correct anyway because it
is in the same position in 'comm' and 'fork' events, but the 'tid' would
have been incorrectly assigned from 'ppid'.
However, for exit events, the kernel puts the current task in the 'ppid'
and 'ttid' which is the same as the exiting task. That is 'ppid' ==
'pid' and if the task is not multi-threaded, 'pid' == 'tid' i.e. the
data goes wrong only when tracing multi-threaded programs.
It is hard to find an example of how this would produce an error in
practice. There are 3 occurences of the fix:
1. perf script is only affected if !sample_id_all which only happens on
old kernels.
2. intel_pt is only affected when decoding without timestamps
and would probably still decode correctly - the exit event is
only used to flush out data which anyway gets flushed at the
end of the session
3. intel_bts also uses the exit event to flush data which
would probably not cause errors as it would get flushed at
the end of the session instead

This patch adds the output of the interrupted machine state (iregs) to
perf script. It presents them as NAME:VALUE so this is easy to parse
during post processing.
To capture the interrupted machine state:
$ perf record -I ....
to display iregs, use the -F option:
$ perf script -F ip,iregs

Milian Wolff reported non functional DWARF unwind under perf script. The
reason is that perf script does not properly configure
callchain_param.record_mode, which is needed by unwind code.
Stealing the code from report and leaving the place for more
initialization code in a hope we could merge it with
report__setup_sample_type one day.

For perf report/script srcline currently only the base file name of the
source file is printed. This is a good default because it usually fits
on the screen.
But in some cases we want to know the full file name, for example to
aggregate hits per file.
In the later case we need more than the base file name to resolve file
naming collisions: for example the kernel source has ~70 files named
"core.c"
It's also useful as input to post processing tools which want to point
to the right file.
Add a flag to allow full file name output.
Add an option to perf report/script to enable this option.

We were storing a copy of kallsyms inside perf.data file so that we
could resolve kernel addresses to function (start, name, mod) tuples,
but that can be achieved using the symbol resolving routines we have
in symbols.c, and that are used elsewhere in tools/perf.
So, do just like 'perf trace' did and ask libtraceevent to use perf's
symbol resolution routines.
The next step is to just skip whatever kallsyms data is embedded in
older perf.data files and finally to stop storing kallsyms in the perf
data file, as the 20-bytes build-id stored in perf.data's header is
enough to find out the right symtab (be it ELF, kcore, kallsyms, etc) to
use.

In addition to using refcounts for the struct thread lifetime
management, we need to protect access to machine->threads from
concurrent access.
That happens in 'perf top', where a thread processes events, inserting
and deleting entries from that rb_tree while another thread decays
hist_entries, that end up dropping references and ultimately deleting
threads from the rb_tree and releasing its resources when no further
hist_entry (or other data structures, like in 'perf sched') references
it.
So the rule is the same for refcounts + protected trees in the kernel,
get the tree lock, find object, bump the refcount, drop the tree lock,
return, use object, drop the refcount if no more use of it is needed,
keep it if storing it in some other data structure, drop when releasing
that data structure.
I.e. pair "t = machine__find(new)_thread()" with a "thread__put(t)", and
"perf_event__preprocess_sample(&al)" with "addr_location__put(&al)".
The addr_location__put() one is because as we return references to
several data structures, we may end up adding more reference counting
for the other data structures and then we'll drop it at
addr_location__put() time.

Instruction tracing will typically have access to information about the
instruction being executed for a particular ip sample. Some of that
information will be available in the 'flags' member of struct
perf_sample.
With the addition of transactions events synthesis to Instruction
Tracing options, there is a need to be able easily to see the flags
because they show whether the ip is at the start, commit or abort of a
tranasaction.
Consequently add an option to display the flags.
The flags are "bcrosyiABEx" which stand for branch, call, return,
conditional, system, asynchronous, interrupt, transaction abort, trace
begin, trace end, and in transaction, respectively.
Example using Intel PT:
perf script -fip,time,event,sym,addr,flags

Enable perf script to use perf.data when it is not owned by current user
or root. Change the short option name of --fields to -F to avoid confusion
with --force.
Example:
# perf record ls
# chown Yunlong.Song:Yunlong.Song perf.data
# ls -al perf.data
-rw------- 1 Yunlong.Song Yunlong.Song 28360 Apr 2 14:53 perf.data
# id
uid=0(root) gid=0(root) groups=0(root),64(pkcs11)
Before this patch:
# perf script
File perf.data not owned by current user or root (use -f to override)
# perf script -f
Error: switch `f' requires a value
usage: perf script [<options>]
or: perf script [<options>] record <script> [<record-options>] <command>
or: perf script [<options>] report <script> [script-args]
or: perf script [<options>] <script> [<record-options>] <command>
or: perf script [<options>] <top-script> [script-args]
-f, --fields <str> comma separated output fields prepend with
'type:'. Valid types: hw,sw,trace,raw. Fields:
comm,tid,pid,time,cpu,event,trace,ip,sym,dso,addr,symoff,period
As shown above, the -f option does not work at all. And -f is already
taken up by --fields, which makes --force confused, so change the short
option name of --fields to -F like what other perf commands do (e.g.
perf report -F) and use -f as the short option name of --force.
After this patch:
# perf script

# perf script -f

Currently vmlinux_path__init() only tries to find vmlinux file from
current directory, /boot and some canonical directories with version
number of the running kernel. This can be a problem when reporting old
data recorded on a kernel version not running currently.
We can use --symfs option for this but it's annoying for user to do it
always. As we already have the info in the perf.data file, it can be
changed to use it for the search automatically.
Before:
$ perf report
...
# Samples: 4K of event 'cpu-clock'
# Event count (approx.): 1067250000
#
# Overhead Command Shared Object Symbol
# ........ .......... ................. ..............................
71.87% swapper [kernel.kallsyms] [k] recover_probed_instruction
After:
# Overhead Command Shared Object Symbol
# ........ .......... ................. ....................
71.87% swapper [kernel.kallsyms] [k] native_safe_halt
This requires to change signature of symbol__init() to receive struct
perf_session_env *.

Move some functions and functionality related to the use of
'addr' out of builtin-script so they can be reused.
The moved functions are: is_bts_event() and sample_addr_correlates_sym()
and a new function perf_event__preprocess_sample_addr() is created from
bits of print_sample_addr().
perf_event__preprocess_sample_addr() is the equivalent of
perf_event__preprocess_sample() but for 'addr' instead of 'ip'.

Change the order of the output to put the srcline last.
It puts the branch 'from address' and 'to address' on the same line,
which is how it would be without the source line reference.
So it makes it consistent and much easier to read.
E.g. old format:
4028fc main+0x2c (/bin/ls)
/build/buildd/coreutils-8.20/src/ls.c:1269 => 40d8a0 set_program_name+0x0 (/bin/ls)
new format:
4028fc main+0x2c (/bin/ls) => 40d8a0 set_program_name+0x0 (/bin/ls)
/build/buildd/coreutils-8.20/src/ls.c:1269

The addr_location struct should fully qualify an address, and to do that
it should have in it the machine where the thread was found.
Thus all functions that receive an addr_location now don't need to also
receive a 'machine', those functions just need to access al->machine
instead, just like it does with the other parts of an address location:
al->thread, al->map, etc.

If --show-task-events option is given, also print internal COMM, FORK
and EXIT events. It would be helpful for debugging.
$ perf script --show-task-events

The intent of perf-script is to dump the events and information in the
file. H/W, S/W and raw events all dump callchains if they are present;
might as well make that the default for tracepoints too.
v2: Only add options for sym, dso and ip if callchains are present

The print_sample_start() will be reused by other printing routine for
internal events like COMM, FORK and EXIT from next patch. And because
they're not tied to a specific event, move the evname print code to its
caller.

Attributes (struct perf_event_attr) are recorded separately in the
perf.data file. perf script uses them to set up output options.
However attributes can also be in the event stream, for example when the
input is a pipe (i.e. live mode). This patch makes perf script process
in-stream attributes in the same way as on-file attributes.
Here is an example:
Before this patch:
$ perf record uname | perf script
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.015 MB (null) (~655 samples) ]

After this patch:
$ perf record uname | perf script
