Description:

This update for libpulp fixes the following issues:

  • Fix ulp tool not patching on highly stressed environments. The reason behind it is that a 10s timeout was not enough depending of how stressed the machine is (bsc#1200316)
  • Fix HANA testcase failures (bsc#1200129)
  • Add support for searching for patches recursively so that to include subdirectories
  • Improve the process patching performance. This is achieved by reducing ptrace calls and switching to 'process_vm_readv/writev' when possible, and moving process discovery to a different thread.
