#9143: feature request: way to set actual program argv -------------------------------------+------------------------------------- Reporter: joeyhess | Owner: simonmar Type: feature | Status: closed request | Milestone: Priority: normal | Version: 7.8.2 Component: Runtime | Keywords: System | Architecture: Unknown/Multiple Resolution: wontfix | Difficulty: Moderate (less Operating System: Linux | than a day) Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by joeyhess): prctl can be used to set the name of a thread. This does not change the process name as displayed by ps. (The stackoverflow article is apparently wrong or out of date or something -- try the sample program there and you'll see it does not change the display in ps, although /proc/pid/task/tid/comm will be changed.) At least on linux when using libbsd's setproctitle, it requires setproctitle_init to first be called and passed the original argv. The libbsd-ctor arranges for this to be done at program startup. So, I was able to get that to work by passing these options to ghc: -lbsd-ctor -optl-u -optllibbsd_init_func -lbsd On linux, using a not very widely used libbsd, and needing linker options to make it work, seems like a rather long way around.. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9143#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
