Subject DO NOT REPLY [Bug 46297] New: apr_temp_dir_get should try /dev/shm in linux

           Summary: apr_temp_dir_get should try /dev/shm in linux
           Product: APR
           Version: HEAD
          Platform: PC
               URL: http://www.mail-archive.com/ganglia-
                    general@lists.sourceforge.net/msg04475.html
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: APR
        AssignedTo: bugs@apr.apache.org
        ReportedBy: carenas@sajinet.com.pe


linux systems since around 2.4.16 are expected to have a tmpfs mounted
filesystem in /dev/shm to support POSIX shared memory (glibc2.2 or later
requires that).

as shown by the linked thread URL, if an application that uses APR calls this
function in a system running linux that has the root partition and /tmp in RO
mode will fail, even if using /dev/shm could had been an alternative.

a workaround is to force the use of /dev/shm by setting TMPDIR but having
libapr try this additional directory in a linux specific way (as it does for
windows/netware) will be better.
