Checking out branches with GetComponents
by Ian Hinder 15 Jun '10

15 Jun '10

Hi, Is it currently possible to specify which branch to check out with GetComponents? For the release, we are planning on making a new branch in each repository which will be the "release branch", called ET_2010_06. For each type of repository (SVN, CVS, git) the einsteintoolkit.th thorn list will be updated to check out this branch. Is this possible? It seems that git clone has a "-b" option to specify which branch to check out after the repository is cloned, but this doesn't seem to exist in anything but the latest versions of git (for example, it exists in 1.7.1 but not in 1.6.1). So a separate "git checkout" command will have to be run by GetComponents. -- Ian Hinder ian.hinder(a)aei.mpg.de

Moving thorn QuasiLocalMeasures into arrangement EinsteinAnalysis
by Erik Schnetter 15 Jun '10

15 Jun '10

Eloisa and I suggest to move the thorn QuasiLocalMeasures into the arrangement EinsteinAnalysis, we are the authors of this thorn. This will circumvent the problems with the CCT cvs server. -erik -- Erik Schnetter <schnetter(a)cct.lsu.edu> http://www.cct.lsu.edu/~eschnett/

GetComponents git-repos vs repos
by Eric Seidel 15 Jun '10

15 Jun '10

Hi all, Last night I made a change to GetComponents that had been requested by a few people; it now clones git, hg, and darcs repos into a single "repos" directory instead of "xxx-repos". I think this is a good change as it removes some clutter and is more tool-agnostic, but unfortunately it is not backwards-compatible. If you try to update ET with the new GetComponents it will error due to the repos directory not existing. There are a few possible solutions I can see, and I'd like your feedback: 1) Everyone could do a clean checkout of ET, and there would be no further issues as all git repos will be cloned into the repos folder. This could be very inconvenient for some people though. 2) I could have GetComponents move existing git/hg/darcs repos into a "repos" folder and then fix the symlinks. This could be dangerous though, as there's always a chance that some files could be clobbered in the process. 3) Erik suggested that I could add some logic to GetComponents for now that will just create symlinks from git-repos etc to repos. That way existing checkouts of ET will be provided with the new repos folder, but without the danger of automatically moving files around. Then at some point in the future we would remove that functionality and enforce the new structure. On the other hand, this would increase clutter in the root directory. Let me know what you think about these ideas, or if you have other suggestions. Thanks, Eric

Cannot update QuasiLocalMeasures
by Erik Schnetter 15 Jun '10

15 Jun '10

When I try to update QuasiLocalMeasures from LSUThorns, I receive the following error message: Updating module: LSUThorns/QuasiLocalMeasures from repository: :pserver:cvs.cct.lsu.edu/numrel located in: Cactus/arrangements cvs [update aborted]: received broken pipe signal ERROR: Could not update module LSUThorns/QuasiLocalMeasures Died at Utilities/Scripts/GetComponents line 1402. There seem to be two problems: - CVS at the CCT is broken - GetComponents should not abort if it encounters an errors; instead, it should skip the module (or the repository?) and report the error message later -erik -- Erik Schnetter <schnetter(a)cct.lsu.edu> http://www.cct.lsu.edu/~eschnett/

No rule to make target 'Riemann1d', needed by `utils' on Damiana

Hi, I am trying to build the ET on Damiana, and everything compiles except the utilities. The Carpet utilities build successfully, but I get an error when it tries to build the GRHydro utility: Building utilities for sim...

QuasiLocalMeasures test cases failing
by Erik Schnetter 14 Jun '10

14 Jun '10

Some of the test cases for the thorn QuasiLocalMeasures are currently failing. I won't have time in the coming week to look at these. Is there a volunteer to look at these test cases? The test cases need to pass before the release. -erik -- Erik Schnetter <schnetter(a)cct.lsu.edu> http://www.cct.lsu.edu/~eschnett/

Changes to Multipole
by Ian Hinder 12 Jun '10

12 Jun '10

Hi all, Multipole is a thorn which provides mode decomposition of grid functions into spherical harmonics, and it is part of the Einstein Toolkit. As the thorn is not yet widely used, and we are approaching a release of the toolkit, I would like to clean up some aspects of the API now before the release. If there are no objections, I will make these changes so that they can be tested as part of the release process. Currently, Multipole has two modes of operation. "all modes" and "specific mode" to determine whether a range of modes from l_min to l_max are computed, or a single l, m mode. Some parameters are shared between these two methods, and this leads to confusion. For example, if you specify "all modes" (the default, and the one everyone will need), then to specify the maximum l_mode you set l_mode = X. You also have to set m_mode otherwise you only get up to m = 2, even though you are getting the higher l modes. I don't think it is necessary to have these two modes of operation, and propose to simplify the interface so that all modes up to a given l_max are computed, for all m. Specifically: Deprecate parameters mode_type, l_min, l_mode, m_mode. Replace with a single new parameter l_max. All modes from l = 0 to l = l_max will be computed. If someone sets l_mode and not l_max, l_mode will be used for l_max to keep backward compatibility for a while. -- Ian Hinder ian.hinder(a)aei.mpg.de

path expansion in git/darcs/hg repositories
by Roland Haas 11 Jun '10

11 Jun '10

Hello all, So my feature request is to have functionality similar to the URL expansion done for svn either in the REPO_PATH variable or in the git URL. The later might be more consistent with with svn but requires some extra logic in the form of way to mark where the actual repository URL ends and where the directory-within-repository part start. We have a thorn SoundSpeed that computes the speed of sound and which lives in its own git repository: Scotch/Soundspeed/.git I would like to be able to do say !TARGET = $ARR !TYPE = git !URL = git://someurl/Scotch/SoundSpeed !AUTH_URL = rhaas3@someotherurl/Scotch/SoundSpeed !REPO_PATH= ../$2 !CHECKOUT = Scotch/SoundSpeed and !TARGET = $ARR !TYPE = git !URL = git://someurl/PersonalCode !AUTH_URL = rhaas3@someotherurl/PersonalCode !REPO_PATH= Cactus/Hydro/$1/experimental/$2 !CHECKOUT = Scotch/SoundSpeed Or if everything was to be encoded in the URL part the way it is done for subversion: !URL = git://someurl/PersonalCode/.git/Cactus/Hydro/$1/experimental/$2 !CHECKOUT = Scotch/SoundSpeed where '.git/' serves as a marker to separate the actual URL of the repository from the path in the repository. Currently neither of this is possible. Patterning after the McLachlan entry, an entry in the thornlist might look like: !TARGET = $ARR !TYPE = git !URL = git://someurl/Scotch/SoundSpeed !AUTH_URL = rhaas3@someotherurl/Scotch/SoundSpeed !REPO_PATH= . !CHECKOUT = Scotch/SoundSpeed This does not work. I get [rhaas3@phys44230 tmp]$ ls -l Cactus1/arrangements/Scotch/ total 0 lrwxrwxrwx 1 rhaas3 phys-numrel 46 Jun 7 13:31 SoundSpeed -> ../../git-repos/SoundSpeed/./Scotch/SoundSpeed Fiddling around with !REPO_PATH by adding '..' does not help either (would work if the repository structure was Scotch/.git) because of the Scotch part of the !CHECKOUT line. Using the $2 syntax I would try !REPO_PATH = ../$2 which does not work either [rhaas3@phys44230 tmp]$ ls -l Cactus2/arrangements/Scotch/ total 0 lrwxrwxrwx 1 rhaas3 phys-numrel 37 Jun 7 13:34 SoundSpeed -> ../../git-repos/SoundSpeed/SoundSpeed since GetComponents only checks for the presence of $2 and then overwrites the whole path by the second part of !CHECKOUT. This is due to line (for rev 630) 905 in handle_git overwriting the whole of $repo_path with $2. Yours, Roland -- My email is as private as my paper mail.
