#2908: Cactus: Fixed arg list too long error. Reporter: Max Morris Status: submitted Milestone: Version: Type: bug Priority: major Component: [https://bitbucket.org/cactuscode/cactus/pull-requests/175](https://bitbucke… There is a check in `lib/make/make.thornlib` to ensure that `sh` is not passed an argument string which is too long. However, this check is not robust enough because it counts words instead of characters/bytes and compares against arbitrary magic numbers rather than checking the max argument string length of the system. I am working on a thorn which fails to build as a direct result of the faulty check. This PR replaces the existing check with a more robust one based on `$ getconf ARG_MAX`, with reasonable fallback behavior if the system shell somehow doesn’t support this command. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2908/cactus-fixed-arg-…

#2907: Arith uses very generic names for its (global) include files

#2907: Arith uses very generic names for its (global) include files Reporter: Roland Haas Status: new Milestone: Version: Type: bug Priority: minor Component: CarpetX Thorn `Arith` in `CarpetX` provides a number of helper functions for arithmetic operations. However it uses a large number of include files in its `interface.ccl` `INCLUDES HEADER` section. Since these file names are globally visible $not even restriction to other thorns `REQUIRE`ing `Arith` or having a `USES HEADER` in their `interface.ccl`, this pollutes \(a$ global name space $namely the `configs/sim/bindings/include/` which _all_ thorns use to search for include files using a `-I` compiler option$. Right now the files are: ‌ ``` INCLUDES HEADER: arr.hxx IN arr.hxx INCLUDES HEADER: cons.hxx IN cons.hxx INCLUDES HEADER: cplx.hxx IN cplx.hxx INCLUDES HEADER: defs.hxx IN defs.hxx INCLUDES HEADER: div.hxx IN div.hxx INCLUDES HEADER: dual.hxx IN dual.hxx INCLUDES HEADER: mat.hxx IN mat.hxx INCLUDES HEADER: rational.hxx IN rational.hxx INCLUDES HEADER: rten.hxx IN rten.hxx INCLUDES HEADER: simd.hxx IN simd.hxx INCLUDES HEADER: smallvector.hxx IN smallvector.hxx INCLUDES HEADER: spvect.hxx IN spvect.hxx INCLUDES HEADER: sum.hxx IN sum.hxx INCLUDES HEADER: ten3.hxx IN ten3.hxx INCLUDES HEADER: tuple.hxx IN tuple.hxx INCLUDES HEADER: vec.hxx IN vec.hxx INCLUDES HEADER: vect.hxx IN vect.hxx ``` of which `vec.hxx` and `vect.hxx` seem to be the most problematic. It may be a good idea to consolidate these into fewer files and / or prefixing with `arith_` or so to create a namespace. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2907/arith-uses-very-g…
