To Pedro and Phil: I hope that developer is responsive to Pedro's supplementary question, but so far he hasn't been. Therefore, Pedro, I suggest you follow Phil's advice to try other wxwidgets help avenues as well such as the "wxWidgets trac system" he mentioned for getting help. Meanwhile, I discovered just this morning that I now have the infinite Yielding loop when attempting to build the test_wxPLplotDemo target. I believe that is the first time that anybody other than Pedro has encountered this issue. And if I use git checkout master^ the test_wxPLplotDemo infinite Yielding loop goes away, i.e., I get 12:43:03: Debug: nanosecs since epoch = 2131058112372533: wxPLplotwindow::wxPLplotwindow 12:43:03: Debug: nanosecs since epoch = 2131058122107520: frame->Create 12:43:03: Debug: nanosecs since epoch = 2131058129943746: wxPLplotwindow::OnCreate 12:43:03: Debug: nanosecs since epoch = 2131058145174385: plD_init_wxwidgets(): enter 12:43:03: Debug: nanosecs since epoch = 2131058145277524: wxPLDevice(): enter 12:43:03: Debug: nanosecs since epoch = 2131058145349163: wxPLDevice(): gc done 12:43:03: Debug: nanosecs since epoch = 2131058145447089: wxPLDevice(): m_interactiveTextGcdc done 12:43:03: Debug: nanosecs since epoch = 2131058145489262: wxPLDevice(): SetDC done 12:43:03: Debug: nanosecs since epoch = 2131058145596088: wxPLDevice(): leave 12:43:03: Debug: nanosecs since epoch = 2131058145629197: plD_init_wxwidgets(): leave 12:43:03: Debug: nanosecs since epoch = 2131058166078403: Plot() But the infinite loop comes back again if I use git checkout master where to be clear master = 995e75e Made some items clearer in the wxWigdets Demo I am pretty sure I tested 995e75e previously by building the test_wxPLplotDemo target without encountering the infinite loop. So it is possible the infinite loop depends on delicate timing conditions that come and go.... However, I also tried Pedro's simple example again, and that does not have an infinite loop this morning. My instincts as release manager are to make another commit that reverses the effect of 995e75e which I believe was also Pedro's plan with a deadline of tomorrow (Friday) if he could not get advice on a definitive fix. However, that might be the wrong thing to do since the issue is we don't really understand what is going on here. For example, making another commit that puts us back to the equivalent of 65e7b3c Fix bug with plotting in wxPLplotDemo may still leave some users out there that experience the infinite loop even when all of Pedro's tests of 65e7b3c and mine seem fine. So I think we really need a fundamental solution for this issue that you guys understand before we release PLplot. So I appreciate you both spending some time on this issue by, e.g., exploring all avenues such as the "wxWidgets trac system" that Phil mentioned for getting help and also reading through wxwidgets documentation and tutorials to try and figure out for yourselves what is going on. In sum, I believe Pedro's plan was to suggest I make that commit to return us to the equivalent of 65e7b3c tomorrow (Friday) if he or Phil got no useful responses to their questions on wxwidgets forums concerning Pedro's simple example of the problem by then. But finding a fundamental solution to this issue is important enough that I think we should put off that commit (if necessary) until 5 days from now (Tuesday,December 27th when I was planning to make the release). And at that point we should decide whether to release using the equivalent of 65e7b3c or delay the release for several more days (and maybe into the first week in 2017) until we do get a fundamental fix that you guys understand. Does that seem like a reasonable plan for dealing with the fairly large release uncertainties created by this issue? Alan __________________________ Alan W.
