Bug #: 13306
Summary: option to skip probes with alias prologue problems
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: translator
AssignedTo: systemtap@sourceware.org
ReportedBy: fche@redhat.com
Classification: Unclassified
Tapset aliases may speculatively manipulate $variables or @cast expressions
that may be expected to fail sometimes. In some cases, the tapset author
may remember to wrap these e.g. in try / catch blocks. As an enhancement
to the existing --skip-badvars option that's narrowly focused on $var
runtime errors, we could introduce an implicit try / catch over alias
prologues:
probe a = foo { ..handler prologue.. }
probe a { ..handler.. }
to expand to:
try {
..handler prologue..
} catch { next }
..handler..
It may make sense to credit such events against the MAXSKIPPED counter.
