@@ -1,5 +1,21 @@ * What's new since version 0.5.14? +- The way in which command line arguments for scripts are substituted has + changed. Previously, $1 etc. would interpret the corresponding command + line argument as an numeric literal, and @1 as a string literal. Now, + the command line arguments are pasted uninterpreted wherever $1 etc. + appears at the beginning of a token. @1 is similar, but is quoted as + a string. This change does not modify old scripts, but has the effect + of permitting substitution of arbitrary token sequences. + + # This worked before, and still does: + % stap -e 'probe timer.s($1) {}' 5 + # Now this also works: + % stap -e 'probe syscall.$1 {log(@1)}' open + # This won't crash, just signal a recursion error: + % stap -e '$1' '$1' + # As before, $1... is recognized only at the beginning of a token + % stap -e 'probe begin {foo$1=5}' * What's new since version 0.5.13? |
