I found a bug in the current version of task. Using recur and a shadow file will
|
|
lead to an infinite loop. To reproduce it, define a shadow file in the .taskrc,
|
|
set a command for it that rebuilds the database, e.g. "list", and then add a
|
|
task with a recurrence set, e.g. "task add due:today recur:1d infinite loop".
|
|
Task will then loop forever and add the same recurring task until it runs out of
|
|
memory. So I checked the source and I believe I found the cause.
|
|
handleRecurrence() in task.cpp will modify the mask, but writes it only after it
|
|
has added all new tasks. Adding the task will, however, invoke onChangeCallback,
|
|
which starts the same process all over again.
