Subject: [RFC][PATCH v2 00/24] tools lib traceevent: Rename pevent to tep for preparation for library
[
Resending as quilt mail threading was broken, but luckily was fixed by
http://git.savannah.nongnu.org/cgit/quilt.git/commit/?id=360b85e1f6b6d1aff5ada942fcee816e1ad7a13c
And has been reported to Debian:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900784
]
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.
