[Buildroot] [PATCH 0/7] General LTTng packages maintenance

[Philippe Proulx]

This patchset updates the Buildroot packages related to the
LTTng project (see <http://lttng.org/>); mostly a bump to the
latest stable release version of the toolkit (2.6.0).

Some packages are renamed to keep them more consistent with
the official project names.

Philippe Proulx (7):
  liburcu: bump to version 0.8.6
  lttng-tools: bump to version 2.6.0
  lttng-libust: bump to version 2.6.0
  lttng-modules: bump to version 2.6.0
  lttng-babeltrace: update Config.in's help
  lttng-libust: rename package to lttng-ust
  lttng-babeltrace: rename package to babeltrace

[Buildroot] [PATCH 7/7] lttng-babeltrace: rename package to babeltrace

[Philippe Proulx]

Although Babeltrace is closely related to the LTTng
project because it can decode LTTng's trace format (CTF),
Babeltrace aims at being an independent framework
for converting traces from one format to another,
whatever the tracer is.

Why? This sort of change should at least be described in the commit
log, since it's clearly not a simple mechanical bump to 2.6.0.

If this is actually needed for lttng-modules to build, then what about
adding some logic in linux/linux.mk to make sure those options are
enabled ?

We already have some logic in linux/linux.mk to enable options for
ktap, so why not for lttng-modules ?

Thanks,

To be honest, I am not sure about those ones. Renaming packages causes
backward compatibility problems (that should be handled by adding the
relevant entries in Config.in.legacy, which your patches is not doing),
so renaming just for the sake of renaming, I'm not sure.

Since they lack the Config.in.legacy handling, I'll mark your patches
as Changes Requested in our patch tracking system. When you'll resubmit
them, I'll try to gather the opinion of other Buildroot developers to
see what they think.

Thanks!

That's actually a mistake. I thought Python was required for tests, but I
forgot about a small Python script that's packaged with LTTng-UST,
called lttng-gen-tp, which helps create tracepoint providers (C files
containing event definitions).

I will resubmit without this.

Because, until today, I didn't know about the special cases in
linux/linux.mk, so thanks for the tip.

Will submit a patch for this later.

 For lttng-libust, I really think it's silly to rename it. Nobody will be
bothered by it.

 Babeltrace on the other hand is more defendable. Are there any other packages
that we carry that produces traces that can be read by babeltrace?

 Note also that there always has been pushback from Peter against gratuitous
renaming.

 Not only legacy handling, but also alphabetical ordering in package/Config.in.

 Arnout

Not that I am aware of, but Philippe might have some more details about

Yes, which is why I decided to not apply those patches for the moment.

I have no strong opinion on this, guys! I renamed those only for them
to be more consistent with the upstream project names.

I don't think any application other than LTTng in Buildroot produces traces
which can be decoded by Babeltrace, but Babeltrace is still an independent
project, reading CTF traces for the moment, also an independent format.
