#420: GCD serial dispatch queues and groups that contain serial queues do not
take surrounding scope reliably within loops/enumerators
-----------------------------------+----------------------------------------
Reporter: johnmacs...@… | Owner: lsansone...@…
Type: defect | Status: new
Priority: blocker | Milestone:
Component: MacRuby | Keywords: GCD
-----------------------------------+----------------------------------------
See attached file with examples.
Summary:[[BR]]
- variables changed during a loop will not get passed correctly to the
serial or group (with serial) queues, and quite often cause crashes.[[BR]]
- if the loop has block variable (eg 100.times do |index|) the variable
will be passed correctly most of the time, but no other changing variables
will be.[[BR]]
[[BR]]
- when the loops are unrolled the dispatch queues take up the variables
correctly - perhaps suggesting that it is yield issue within the
enumerators.
