Fellows: I found useful add UnixTime at the beginning of file names for you have nnnFoo.etc what is compatible with different OS and you easily see ordered . But I my image I do not have how convert this value to DateAndTime again. So i attach this just in case some could use it.

I'm noticing the Squeak write cursor appearing even when another app is in front. Is this new?

>1 hour to garbage collect
by Chris Muller 19 Nov '16

19 Nov '16

I finally figured out what I thought was a bug in my own code was actually just exposing something about Spur which I had never experienced before -- *incredibly* long time for it to garbage collect. I kept thinking the image was locking up, but in fact it was just doing a GC and does eventually come back. But, clearly, something has GOT to be wrong here... Eliot? Should GC take I put in some debugging statements into source.squeak.org's start-up initialization which give us essential VM information at each step, check it out. =========== *** First before doing anything, snapshot the VM parameters 2016-11-18T15:05:07.256516-06:00 Virtual Machine Parameters 2016-11-18T15:05:07.25729-06:00 -------------------------- 2016-11-18T15:05:07.257693-06:00 #1 118,531,328 size of old space 2016-11-18T15:05:07.257781-06:00 #2 2,368,536 size of new space 2016-11-18T15:05:07.257838-06:00 #3 125,304,832 size of heap 2016-11-18T15:05:07.258414-06:00 #7 2 full GCs since startup 2016-11-18T15:05:07.258471-06:00 #8 330 total milliseconds in full GCs since startup 2016-11-18T15:05:07.258521-06:00 #9 72 scavenging GCs since startup 2016-11-18T15:05:07.258588-06:00 #10 26 total milliseconds in scavenging GCs since startup 2016-11-18T15:05:07.258639-06:00 #11 2,249 tenures of surving objects since startup *** Looks good, so load the SSRepository object and indexes from Magma 2016-11-18T15:05:07.258706-06:00 Loading SSRepository... 2016-11-18T15:07:54.675452-06:00 Loading Indexes... 2016-11-18T15:07:54.679669-06:00 Virtual Machine Parameters 2016-11-18T15:07:54.679771-06:00 -------------------------- 2016-11-18T15:07:54.679842-06:00 #1 806,397,184 size of old space 2016-11-18T15:07:54.679909-06:00 #2 1,086,968 size of new space 2016-11-18T15:07:54.679985-06:00 #3 813,170,688 size of heap 2016-11-18T15:07:54.680058-06:00 #7 17 full GCs since startup 2016-11-18T15:07:54.680126-06:00 #8 6,699 total milliseconds in full GCs since startup 2016-11-18T15:07:54.680191-06:00 #9 8,977 scavenging GCs since startup 2016-11-18T15:07:54.680255-06:00 #10 96,048 total milliseconds in scavenging GCs since startup 2016-11-18T15:07:54.680319-06:00 #11 15,015,301 tenures of surving objects since startup *** 2 minutes since startup, so far so good, but now do a "Smalltalk garbageCollect"... 2016-11-18T15:07:54.680384-06:00 Garbage collecting now... 2016-11-18T16:25:38.072284-06:00 *0:01:17:43.39 to GC after initialization.* 2016-11-18T16:25:38.075849-06:00 Virtual Machine Parameters 2016-11-18T16:25:38.075949-06:00 -------------------------- 2016-11-18T16:25:38.076023-06:00 #1 705,733,888 size of old space 2016-11-18T16:25:38.076092-06:00 #2 694,752 size of new space 2016-11-18T16:25:38.076158-06:00 #3 712,507,392 size of heap 2016-11-18T16:25:38.076227-06:00 #7 18 full GCs since startup 2016-11-18T16:25:38.076297-06:00 #8 4,670,088 total milliseconds in full GCs since startup 2016-11-18T16:25:38.076366-06:00 #9 8,977 scavenging GCs since startup 2016-11-18T16:25:38.076434-06:00 #10 96,048 total milliseconds in scavenging GCs since startup 2016-11-18T16:25:38.076506-06:00 #11 15,015,301 tenures of surving objects since startup 2016-11-18T16:25:44.141442-06:00 *** Checking integrity of the repository... ============ I *think* there is only one such of these super-long GC's, afterward it returns to normal, short GC times. So, I guess I will move forward with deploying my latest code which I thought was locking the image, but apparently not. But this super-long GC is problematic in any case. Eliot, is there any case for Spur to take so long and report those numbers which I could avoid? In years of using Spur, I've never actually noticed this issue before... I'm really puzzled.
