Having libtraceevent turn into a proper library has long been asked for.
I never had time to do it before. Luckily, Tzvetomir was able to spend
the time to start the preparation. The first thing that needs to be done
is to handle namespace collisions. "pevent" was the prefix I chose, but
many people were displeased by it, as it didn't express what the functions
were used for. After discussing with many people at many conferences
I've come up with "tep", which means "Trace Event Parser". Please don't
question this. The bikeshed has been painted and I'm not changing the
color.
This series changes all the function names and data structures from the
"pevent_" prefix to the "tep_" prefix. Note, it does not change the
names of local variables or even parameters. "pevent" variables and
parameters still exist. We can change those later, but for now, I want
all global references to "pevent" to be "tep_" instead.
This is not complete. It is only one of many preparations to make
libtraceevent into a legitimate library. There's other naming conventions
that will be made. But for now, I would like to hear thoughts about
this change before we proceed further.
Instead of doing one big update, Tzvetomir grouped changes together.
I compiled each patch to make sure perf still builds without errors
at each step. I only used my own configuration, thus there may be
cases that perf might fail to build. Here's what I had:
Auto-detecting system features:
... dwarf: [ on ]
... dwarf_getlocations: [ on ]
... glibc: [ on ]
... gtk2: [ on ]
... libaudit: [ OFF ]
... libbfd: [ on ]
... libelf: [ on ]
... libnuma: [ OFF ]
... numa_num_possible_cpus: [ OFF ]
... libperl: [ OFF ]
... libpython: [ on ]
... libslang: [ OFF ]
... libcrypto: [ on ]
... libunwind: [ OFF ]
... libdw-dwarf-unwind: [ on ]
... zlib: [ on ]
... lzma: [ on ]
... get_cpuid: [ on ]
... bpf: [ on ]
The above is the config I used for testing the build.

Sorry for the messed up threading. I'm using quilt to send the email,
and it appears that Debian testing pulled in a broken version that
doesn't thread the patches properly. It was fixed over a year ago!
http://git.savannah.nongnu.org/cgit/quilt.git/commit/?id=360b85e1f6b6d1aff5ada942fcee816e1ad7a13c
But Debian testing still has the broken version (and I just recently
updated to it!). I'll be reporting this to Debian.
I'll send out a v2 that fixes the threading. Sorry about this :-(

I just pushed it to my repo:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git
branch: tip/perf/core
Based off of commit ec2cb7a526d49b65576301e183448fb51ee543a6 from tip's
perf/core tree.

right, I can see more things that needs rename, like in print_arg*,
trace_* stuff and others
I'm also getting weird make error when compiling in libtraceevent dir:
[jolsa@krava traceevent]$ make
GEN libtraceevent-dynamic-list
Either missing one of [ plugin_jbd2.so plugin_hrtimer.so plugin_kmem.so plugin_kvm.so plugin_mac80211.so plugin_sched_switch.so plugin_function.so plugin_xen.so plugin_scsi.so plugin_cfg80211.so] or bad version of nm
but that seems to be there even without your patchset,
so probably something we should look into
other than that it looks ok to me
once this is done, we can move forward to put this
to kernel-tools-libs-devel rpm
thanks,
jirka

We are working on renaming the other data structures. As for the
"trace_" it is really "trace_seq_*" That's not going to get renamed. We
may move it to another header file. It matches the trace_seq_* code in
the kernel, and I would like to keep that the same.

For this patch series, do you want to take the patch set, or just pull
from my branch?

Arnaldo takes care of that, but I guess pulling from branch is the prefered way

I'll try pulling and building it automatically patch by patch,

Hi Arnaldo,
Were you able to take this? We have another patch series that's ready
to go (it can wait till after the merge window though).

OK, cool. I don't have Arnaldo's branch, but was looking for tip pulls.

Its going to Ingo today, it passed all tests, together with other
patches for this pull req:
Test results:
The first ones are container (docker) based builds of tools/perf with
and without libelf support. Where clang is available, it is also used
to build perf with/without libelf, and building with LIBCLANGLLVM=1
(built-in clang) with gcc and clang when clang and its devel libraries
are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
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.
