I've got a groovy script that I call using load() in my Jenkinsfile. I needed it to call itself with a different parameter when exception handling. However, it doesn't call itself in a way you would expect:
def call(in_path) {
timeout(1) {
def my_path = in_path
print "Start of call(${my_path}) FINDMEAGAIN"
lock ("mylock") {
print "Start of call(${my_path}):lock block"
try {
print "Start of call(${my_path}):try block"
error "Nope!"
} catch (err) {
print "In Exception - calling self"
def my_pathp = my_path + "X"
if (my_pathp.length() < 50) {
print "Calling call(${my_pathp})"
call(my_pathp)
}
print "Back to call(${my_path})"
}
}
return null
}
}
You would expect to see the FINDMEAGAIN in the console multiple times. Or you would expect the lock to hang trying to re-lock. Instead, I get this:
Start of call(rpms/centos7) FINDMEAGAIN
[Pipeline] lock
Trying to acquire lock on [mylock]
Lock acquired on [mylock]
[Pipeline] {
[Pipeline] echo
Start of call(rpms/centos7):lock block
[Pipeline] echo
Start of call(rpms/centos7):try block
[Pipeline] error
[Pipeline] echo
In Exception - calling self
[Pipeline] echo
Calling call(rpms/centos7X)
[Pipeline] echo
Start of call(rpms/centos7):lock block
[Pipeline] echo
Start of call(rpms/centos7):try block
[Pipeline] error
[Pipeline] echo
In Exception - calling self
[Pipeline] echo
Calling call(rpms/centos7X)
[Pipeline] echo
Start of call(rpms/centos7):lock block
[Pipeline] echo
Start of call(rpms/centos7):try block
[Pipeline] error
[Pipeline] echo
In Exception - calling self
This repeats until a stack overflow. I assume the variables not changing is a groovy thing concerning references vs copies or something, but that doesn't explain why the call is not going to the top.
In experimenting, I found that if this snippet wasn't in call(), but something defined above it and called within, it worked as expected.
