[Einstein Toolkit] #456: Ensure functions are not defined twice

#456: Ensure functions are not defined twice -------------------------+-------------------------------------------------- Reporter: hinder | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- When multiple source files define non-static functions with the same name, these are all compiled together into the resulting executable. Which one gets called is not predictable by the user. This can happen if a user copies a thorn, modifies it slightly, and compiles both thorns into the same configuration. This can lead to *very* difficult-to-find bugs, and it would be helpful if Cactus was able to prevent this, or at least to mitigate the problem. At the CST level, Cactus should be able to tell that there are two thorns which schedule functions with the same name. At the moment, this is not caught. I propose that this should be a fatal error, as there is no way to predict which function will be called eventually. This will solve the problem in some cases, but not in the case where there are instances of duplicate function names which are not scheduled. It should be possible to scan the object/library files using standard tools (nm etc) to determine if there are multiple globally visible symbols with the same name. There might even be standard tools for this purpose. Doing this in a portable way might not be straightforward, but having an implementation for Linux, for example, would catch the majority of cases. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/456> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #447: simfactory 1.0 always uses -L 3

#447: simfactory 1.0 always uses -L 3 ----------------------------------------------+----------------------------- Reporter: alexander.beck-ratzka@… | Owner: eschnett Type: defect | Status: new Priority: major | Milestone: Component: SimFactory | Version: Keywords: | ----------------------------------------------+----------------------------- The perl version of simfactory always uses the debugging loglevel for simulations. The loglevel of a cactus simulation can be specified by setting -L to a value between 0 (none) and 3 (debug). While the cactus default is 0, simfactory sets it to 3. The debug loglevel could lead to huge output files. I would suggest to set it to the cactus default, and allow a user to increase it. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/447> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#346: Detect when --reconfig is necessary ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Other | Version: Keywords: | ----------------------+----------------------------------------------------- Cactus sometimes outputs an error message that a configuration needs to be reconfigured. Simfactory should notice this, and then automatically build with --reconfig. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/346> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #907: TRAC: allow to create a ticket with review state

#907: TRAC: allow to create a ticket with review state ----------------------------------+----------------------------------------- Reporter: bmundim | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Component: EinsteinToolkit trac | Version: Keywords: TRAC | ----------------------------------+----------------------------------------- Sometimes we want to create a ticket with an attached patch and assign the ticket to be reviewed. That should be possible with only one "modify ticket". Currently we need to create the ticket with the attachment and then modify the ticket afterwards to review state. The problem is that sometimes we forget to change to review state. It would be nice to do it all at once. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/907> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #229: Using a nonexistent header file should lead to an error message

#229: Using a nonexistent header file should lead to an error message --------------------+------------------------------------------------------- Reporter: hinder | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Cactus | Version: Keywords: | --------------------+------------------------------------------------------- If I have the following in my interface.ccl, USES INCLUDE: vectors.h but no thorn in my thornlist provides this header file, there is no error at compile time. Further, if I #include this file in my source file, an empty file is included, which means that again I don't get an error. The first indication that something is wrong is that the contents of the header file are not available, which makes debugging the problem with the thornlist very confusing. I propose that the CST should emit a fatal error if one of the thorns tries to use a header file which does not exist. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/229> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #905: NaNs in ADMBase::gxx using Development Version of ET

#905: NaNs in ADMBase::gxx using Development Version of ET ---------------------------------+------------------------------------------ Reporter: yosef@… | Type: defect Status: new | Priority: major Milestone: | Component: Other Version: | Keywords: ---------------------------------+------------------------------------------ While testing the CCE in the ET, I stumbled across an issue interpolating the admbase::metric at CCTK_POSTSTEP in GLOBAL mode at particular spatial points. The "bug" (or parfile/scheduling error) seems to be sensitive to the exact grid setup. Basically, when I use the qc0-mclachlan-CCE_Cauchy.par parfile, I get nans for gxx. I made a small test thorn that only interpolates gxx at a particular point. Nans show up at iteration 1. attached is the parfile I used and the test thorn. Here is the output from the above test thorn: gxx(3.966899,0.000000,-17.630662) = 1.1160523626974641 at iter 0 on proc 1 gxx(3.966899,0.000000,-17.630662) = 1.1160523626974641 at iter 0 on proc 0 gxx(3.966899,0.000000,-17.630662) = -nan at iter 8 on proc 1 gxx(3.966899,0.000000,-17.630662) = -nan at iter 8 on proc 0 gxx(3.966899,0.000000,-17.630662) = -nan at iter 16 on proc 1 gxx(3.966899,0.000000,-17.630662) = -nan at iter 16 on proc 0 etc.... -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/905> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #705: Activation Order in Parameter Files

#705: Activation Order in Parameter Files -------------------------+-------------------------------------------------- Reporter: sbrandt | Owner: Type: enhancement | Status: new Priority: minor | Milestone: Cactus_4.1.0 Component: Cactus | Version: Keywords: | -------------------------+-------------------------------------------------- At the moment the ActiveThorns list is sensitive to the order in which thorns are activated if the ActiveThorns parameter is updated multiple times. However, it is not sensitive to the order in which thorns are activated if all thorns are specified in a single line. This inconsistency should be removed, and the order should not matter in either case. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/705> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
