Hi all,
Toward the end of last year, the good folk at SGI asked whether
we could make kmchart more a part of PCP. In particular, there
was discussion of whether there should be one source tree, and
using the same naming convention as the other PCP tools.
With the pending release of additional (SGI) monitoring tools,
it would be good to have these issues sorted out, so there is
clarity on where that code should end up in the oss releases.
I'd like to solicit input before I go ahead and make any changes
in this area. I only want to have to do this once, never again!
If you have any thoughts or strong preferences on the direction
taken (particularly with the planned actions outlined below),
please let me know sooner rather than later.
These are my thoughts/opinions/preferences:
- I don't want to attempt to merge the two git trees, too much
valuable revision history now exists, and the configure.in that
is needed for each is very different (different tool chain)
- I don't want a single install package (eg. named "pcp") as
the "kmchart" package has lots of additional (GUI) dependencies.
- Renaming kmchart/kmtime -> pmchart/pmtime is fine with me. I
will keep symlinks for backward compatibility, etc.
- Need a new name for the "kmchart" package. Suggestions have
included: pcpgui, pcpvis, pcpviz, pcpmon, pcp-monitor. At the
moment I'm favouring the last two, probably the last one as it
is the most clear.
These are my planned actions:
- rename the kmchart git tree to pcp-monitor
- rename the current pcp git tree to pcp-collector (removing any
ambiguity, and making the packages consistent with some of the
existing documentation)
- split the current pcp rpm package into libraries, development
packages and one pcp-collector package (pcp-3.0 timeframe, this
has been requested by someone wishing to package us in Fedora).
- rationalise libqmc and libpmc into one library as part of this
transition (one library in the pcp-monitor package, not pcp),
and rename kmdumptext to pmdumptext in the process.
- Remove references to C++ compiler in pcp-collector configure
process - all C++ code should end up in pcp-monitor hereafter.
- rename libkmtime to libpmtime (this is a static-only lib atm,
thankfully, but we should switch to making that shared as well).
- update man pages, web pages, code, etc that refers to the km*
names and instead use pm* names.
- move pcpqa tree contents (back) into "qa" subdirectory in the
pcp-collector git tree, so its clear what that is for. kmchart
(aka pcp-monitor) already has a "qa" subdirectory.
These things are likely to be done piece-by-piece and will take
time. I'm also trying to focus on the native Windows PCP port
at the moment (so, even more time), but would like to use the
right names for km{chart,time,etc} in the first version of that.
OK, any thoughts? Suggestions? Alternatives? Personally, I
think these are very positive changes, especially for new users
by removing the wierd historical naming oddities that have crept
into how we package things.
cheers.
