[Einstein Toolkit] #1396: Display prompts of executed commands

#1396: Display prompts of executed commands ---------------------------+------------------------------------------------ Reporter: rhaas | Owner: eric9 Type: enhancement | Status: new Priority: optional | Milestone: Component: GetComponents | Version: development version Keywords: | ---------------------------+------------------------------------------------ the attached patch goes to some lengths to capture both stdout and stderr when executing commands and displays each line of output as it is generated by the command. This is useful for programs that output prompts to stdout and wait for user input afterwards. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1396> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #2026: param.ccl parser writes (debug?) files v1 and v2 into Cactus root

#2026: param.ccl parser writes (debug?) files v1 and v2 into Cactus root --------------------+------------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: development version Keywords: | --------------------+------------------------------------------------------- The file parametre_parser.pl contains {{{ open($fd,">v1") or die; print $fd $v1,"\n"; close($fd); open($fd,">v2") or die; print $fd $v2,"\n"; close($fd); }}} causing it to create files v1 and v2 in the main Cactus root. Without having looked into this in any more details, this smells like debug output that should be removed before the release. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2026> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#68: GetComponents hang due to certificate issues. --------------------------------+------------------------------------------- Reporter: diener@… | Owner: eric9 Type: defect | Status: new Priority: major | Milestone: Component: GetComponents | Version: ET_2010_06 Keywords: | --------------------------------+------------------------------------------- I did a complete new checkout of the EinsteinToolkit on numrel06 using the version of GetComponents available on the EinsteinToolkit web pages and had GetComponents hang with no errors or warnings when checking out AEIThorns/AEILocalInterp. Trying the checkout manually I got: Error validating server certificate for 'https://svn.aei.mpg.de:443': - The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually! Certificate information: - Hostname: svn.aei.mpg.de - Valid: from Tue, 23 Feb 2010 16:02:12 GMT until Sun, 22 Feb 2015 16:02:12 GMT - Issuer: Max-Planck-Gesellschaft, DE - Fingerprint: 03:b4:e8:6e:d9:09:e9:93:72:e9:ff:fa:df:e4:2c:6d:1d:2a:e4:66 (R)eject, accept (t)emporarily or accept (p)ermanently? p After accepting the certificate and restarting the checkout proceeded without problems. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/68> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#2076: fix stripping of sourcedir path ------------------------+--------------------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: SimFactory | Version: development version Keywords: backport | ------------------------+--------------------------------------------------- Commit d6e4f58 - sim-sync: handle symbolic links more gracefully (1 year, 6 months ago) <Roland Haas> introduced a bug that manifest in error messages of the form "mkdir: cannot create directory `/ET_Hack': Permission denied". Pull request is https://bitbucket.org/simfactory/simfactory2/pull- requests/21/simlib-correct-stripping-of-first-part/diff This should be backported to the release as it is very annoying to not even be able to use sim sync to transfer code. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2076> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #181: AEILocalInterp should not off-centre the interpolation stencil by default

#181: AEILocalInterp should not off-centre the interpolation stencil by default ----------------------------+----------------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: AEILocalInterp | ----------------------------+----------------------------------------------- AEILocalInterp by default will off-centre the interpolation stencil if there are insufficient points to perform the interpolation. In a parallel setting, this could happen due to there being insufficient ghost points for the interpolator chosen. The off-centering leads to an interpolation error which is of the correct order but larger than for a centered stencil. More importantly, it leads to different results on different numbers of processes. This violates a basic design principle of Cactus, and the expectation of users, that changing the number of processors should not change the results of a simulation. I propose that instead of silently off-centering the stencil, AEILocalInterp should abort with an error indicating that there are insufficient ghost-zones. The interpolator options corresponding to this are: boundary_off_centering_tolerance={0.0 0.0 0.0 0.0 0.0 0.0} boundary_extrapolation_tolerance={0.0 0.0 0.0 0.0 0.0 0.0} -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/181> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#2085: ET header bar covers text for mid-sized window width -------------------------------------+-------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit website | Version: development version Keywords: | -------------------------------------+-------------------------------------- The ET bar (at least for my browser and my OS and my screen) covers part of the website for mid-sized (and small though not all will show it) windows. Please see attached screenshots. Mostly it just seems to affect the headings but that seems to be accidental. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/2085> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
