Upcoming p4est release

[carsten....@gmail.com]

Hi everybody,

I'm about to bump the p4est master branch significantly. Could some of you please check whether the current develop branch on github works with deal.ii?

Will do, ETA ~24h.

I will also review the debian specific patches (only tiny modifications
for the build system and to comply with debian policies) whether
something is worth upstreaming. If yes, I'll make a pull request on
github.

Best,
Matthias

Results are looking very good so far:

- Current development versions for libsc/p4est cleanly compile and
install on Gentoo

- I have run (the designated point release v8.4.2-rc1-4-g01b5209)
against current development versions

cburstedde/libsc 26c385e8dbe5e230c2dbf9d26c91e06e5eea31cd
cburstedde/p4est 30c1d08ac57fe86f6d89d5943958cbf232029ee1

The results are here [1]. We have 21 failing tests in the
distributed_grids and codim_one categories due to a minor change in
p4est's (non-binary) vtk output:

--- output Thu Sep 1 23:50:33 2016
***************
*** 8,15 ****
</PPoints>
<PDataArray type="Int32" Name="treeid" format="ascii"/>
</PCellData>
- <PPointData>
- </PPointData>
<Piece Source="file_0000.vtu"/>
</PUnstructuredGrid>
</VTKFile>

If this remains the new output I will simply upload output variants for
the deal.II testsuite once a new p4est version is released.


Currently, I am running the development version against above
libsc/p4est checkouts.

Again, thanks a lot for the heads-up!
Matthias

This is a fairly old p4est/master. Could you try p4est/develop?

Maybe the VTK change is for the better. Unless people find their VTK viewers complaining now.

Just bumped p4est master. Feel free to go ahead with the test suite. :)

p4est: 0e7e786101985fa7ee01323d32d1577768455f85
libsc: 26c385e8dbe5e230c2dbf9d26c91e06e5eea31cd

I gave it a short run. Looks fine as well!

Best,
Matthias
