Bug #: 15481
Summary: stapdyn end probes fail with a -c command
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: dyninst
AssignedTo: systemtap@sourceware.org
ReportedBy: jistone@redhat.com
Classification: Unclassified
With the new stapdyn transport, no end probes fire at all when there's a target
command given. First command is good; the second missed 'end':
$ stap -e 'probe begin, end { println(pp()) }' --dyninst
begin
end
$ stap -e 'probe begin, end { println(pp()) }' --dyninst -c true
begin
Timing reports are similarly affected:
$ stap -e 'probe begin, end { println(pp()) }' --dyninst -t
begin
end
----- probe hit report:
begin, (<input>:1:1), hits: 1, nsecs: 4352min/4352avg/4352max, from: begin,
index: 0
end, (<input>:1:1), hits: 1, nsecs: 481min/481avg/481max, from: begin, index: 1
$ stap -e 'probe begin, end { println(pp()) }' --dyninst -c true -t
begin
ERROR: Couldn't reserve any print buffer space
ERROR: Couldn't reserve any print buffer space
WARNING: Number of errors: 0, skipped probes: 0
WARNING: Skipped due to reentrancy: 1
A git-bisect brought me to commit 8ca891c, when the new transport was added.
