#8248: GHCi should not fail to honour ghci.conf or .ghci if group writable -------------------------------------+------------------------------------- Reporter: afcowie | Owner: whisky Type: bug | Status: closed Priority: normal | Milestone: 7.10.2 Component: GHCi | Version: 7.6.3 Resolution: wontfix | Keywords: Operating System: Linux | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: #9324 | Differential Rev(s): Phab:D805 Wiki Page: | -------------------------------------+------------------------------------- Comment (by anohigisavay): I just got hit by this issue. I have been using ACL for more granular permission control. I created two users to access different desktop environments to avoid certain conflict issues, while essentially they are the same user and should be able to access each other's home directory without any problem. When ACL is enabled the group permission bits in the traditional UGO mechanism act as the mask for ACL (i.e. the maximum available permission for ACL_USER, ACL_GROUP_OBJ and ACL_GROUP). Thus it must be set to `rw-` instead of `r--`. This limitation renders ACL ineffective for the home directory. While it is obviously overkilling for GHCi to consider all these security enhancement mechanisms (SELinux and others also exist), I suggest we can leave the choice between security and flexibility to the users. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8248#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
