DESCRIPTION

This eclass provides functionality which assists with installing virtual machines, and ensures that they are recognized by java-config.

FUNCTIONS

java-vm-2_pkg_setup

default pkg_setup

Initialize vm handle.

java-vm-2_pkg_postinst

set_java_env

java-vm_set-pax-markings

Set PaX markings on all JDK/JRE executables to allow code-generation on the heap by the JIT compiler.

The markings need to be set prior to the first invocation of the the freshly built / installed VM. Be it before creating the Class Data Sharing archive or generating cacerts. Otherwise a PaX enabled kernel will kill the VM. Bug #215225 #389751

  Parameters:
    $1 - JDK/JRE base directory.

  Examples:
    java-vm_set-pax-markings "${S}"
    java-vm_set-pax-markings "${ED}"/opt/${P}

java-vm_revdep-mask

Installs a revdep-rebuild control file which SEARCH_DIR_MASK set to the path where the VM is installed. Prevents pointless rebuilds - see bug #177925. Also gives a notice to the user.

  Parameters:
    $1 - Path of the VM (defaults to /opt/${P} if not set)

  Examples:
    java-vm_revdep-mask
    java-vm_revdep-mask /path/to/jdk/

java-vm_sandbox-predict

Install a sandbox control file. Specified paths won't cause a sandbox violation if opened read write but no write takes place. See bug 388937#c1

  Examples:
    java-vm_sandbox-predict /dev/random /proc/self/coredump_filter

install_mozilla_plugin

ECLASS VARIABLES

JAVA_VM_BUILD_ONLY = "${JAVA_VM_BUILD_ONLY:-FALSE}": Set to YES to mark a vm as build-only.
