(fatal): New function. * stap-find-or-start-server: Source stap-env. Use $stap_exec_prefix. Always exit with 0. * stap-start-server: Source stap-env. Check for the server PID as a running process and for avahi-publish-service running as a child in order to verify that the server is ready. * stap-add-server-cert: Renamed to stap-authorize-server-cert.

* Clean up the autoconf cachingJosh Stone2009-02-071-0/+1
| | | | | | | | | | | | | | | | | This makes the stapconf caching process quite a bit more transparent. The options are now cached in a header file as #defines, and this header file is a normal build dependency instead of calling so many make $(shell ...) commands. * buildrun.cxx (compile_pass): Pull in autoconf options in a header of #defines rather than -DXXX, and make that header a build dependency. * buildrun.cxx (output_autoconf): New function to consolidate the computation of each autoconf test. * cache.cxx (add_to_cache, get_from_cache, clean_cache): Start treating the stapconf header as a first-class cached item. * cache.h: Move definitions of things only needed in cache.cxx * hash.cxx (find_stapconf_hash): Generate stapconf_name as a .h now. * main.cxx (main): Default the stapconf_name based on getpid().

* Fix mkdtemp() umask issuefche2008-01-021-0/+2
| | | | | | | | | | | | | | | | | | | | | Even though the mkdtemp() man page indicates that the directory will be created with always 0700 permissions, it is actually affected by the process's umask. So, if you run stap with an unusual umask it can end up creating the temp dir with permissions that staprun can't handle e.g.: $> rpm -q systemtap systemtap-0.6-1.fc9 $> umask 0122 $> stap -e 'probe begin { println("foo") exit() }' ERROR: Error opening '/tmp/stapV4pBIb/stap_725b9bc541cef2618a5ccbc58bb64d15_287.ko': Permission denied Obvious solution is to briefly set the umask to zero in stap so as to ensure 0700 permissions.
