[JENKINS-63696] The timeout activity flag extends the time by one and a half times

My pipeline has the following options:

  

options {

     timestamps ()

     timeout(activity: true, time: 30, unit: 'SECONDS')

 }

 

And canceling the job occurs after 45 seconds:

22:12:00 Timeout set to expire after 30 sec without activity

[Pipeline] {

[Pipeline] stage

[Pipeline] { (Reservation)

[Pipeline] script

[Pipeline] {

[Pipeline] input

22:12:00 Input requested

22:12:45 Cancelling nested steps due to timeout

This happens for every time I was set (SECONDS, MINUTES and HOURS) - and every time was extended by one and a half times.

  

But if I changed my pipeline options to:

options {

 timestamps ()

 timeout(activity: false, time: 30, unit: 'SECONDS')

 }

 

Every things is ok (sample log):

 

21:36:24  Timeout set to expire in 30 sec 

[Pipeline] { 

[Pipeline] stage 

[Pipeline] { (Reservation) 

[Pipeline] script 

[Pipeline] { 

[Pipeline] input 

21:36:24 Input requested 

21:36:54 Cancelling nested steps due to timeout

  

Timeout was called after exactly 30 seconds.

 

I tested this on two different Jenkins instances, and for both I have the same result, as I described above.

Raw content of original issue

My pipeline has the following options:


  



options {

     timestamps ()

     timeout(activity: true, time: 30, unit: 'SECONDS')

 }



 


And canceling the job occurs after 45 seconds:




22:12:00 Timeout set to expire after 30 sec without activity

[Pipeline] {

[Pipeline] stage

[Pipeline] { (Reservation)

[Pipeline] script

[Pipeline] {

[Pipeline] input

22:12:00 Input requested

22:12:45 Cancelling nested steps due to timeout



This happens for every time I was set (SECONDS, MINUTES and HOURS) - and every time was extended by one and a half times.


  


But if I changed my pipeline options to:



options {

 timestamps ()

 timeout(activity: false, time: 30, unit: 'SECONDS')

 }



 


Every things is ok (sample log):

  



21:36:24  Timeout set to expire in 30 sec 

[Pipeline] { 

[Pipeline] stage 

[Pipeline] { (Reservation) 

[Pipeline] script 

[Pipeline] {

Timeout was called after exactly 30 seconds.
