nuSqueak source

Hi, I heard that people got a new problem in inputting Japanese text into Scratch 1.4 running on Raspberry Pi OS after, or around the version 2020-08-20. I would like to take a look at it but it might involve recompiling and generating the VM with debugging info. Last time I looked into it was years and years ago and I need to basically make a fresh start. Is the process of making NuSqeauk VM For Raspberry Pi up to date and straightforward? Can people point me to the right point to start? Thanks! -- -- Yoshiki

CI status

Hi all, I have restored (I think) the green status of minheadless build. We could eventually authorize failure of all those builds, or restrict the number of flavours that we build (it takes really loooong time before we get CI feedback). But if we abandon all those now, I fear that we never catch up; it's a one way ticket. IMO there are still interesting ideas to take, even if development has continued in Pharo fork... Now the next failing build on travis is about squeak.cog.v3. Did some incompatible VM change took place? For example https://travis-ci.org/github/OpenSmalltalk/opensmalltalk-vm/jobs/738831149 ###################################################### # Squeak-4.6 on Travis CI (2278.23) # # 3401 Tests with 5 Failures and 0 Errors in 112.13s # ###################################################### ######################### # 5 tests did not pass: # ######################### SUnitToolBuilderTests 837fef_266b ✗ #testHandlingNotification (10023ms) TestValueWithinFix 2a65cb_266b ✗ #testValueWithinTimingBasic (1005ms) e9a7ab_266b ✗ #testValueWithinTimingNestedInner (1001ms) c57415_266b ✗ #testValueWithinTimingNestedOuter (1002ms) e89da3_266b ✗ #testValueWithinTimingRepeat (3004ms) Executed 3401 Tests with 5 Failures and 0 Errors in 112.13s. To reproduce the failed build locally, download smalltalkCI, and try to run something like: bin/smalltalkci -s Squeak-4.6 --headfull /path/to/.smalltalk.ston
