SqueakSSL fixes
by GÃ¶ran Krampe Feb. 16, 2014

Feb. 16, 2014

Hey! Ok, so I sat down and "packaged" some fixes to mainly iOS SqueakSSL that we have done here at 3DICC. We have no intention to keep stuff like this for ourselves, but daily we work using our own repos so it needs some attention and time to get it out there :) Sorry if this email is long but I just wanted to make it easy for people to know how to integrate this. The fixes span: * A new SqueakSSL Monticello package, that has other fixes too done at 3DICC. I haven't looked through them all in detail, so here a bit of manual cherry picking is needed. For example we removed some "compatibility code" for Squeak 4.2 causing us some problems. * Modified platform files: platforms/Cross/plugins/SqueakSSL/SqueakSSL.h platforms/iOS/plugins/SqueakSSL/sqMacSSL.c platforms/unix/plugins/SqueakSSL/sqUnixOpenSSL.c platforms/win32/plugins/SqueakSSL/sqWin32SSL.c I have so far only tested the new sqMacSSL.c on iOS - OSX 10.8.5. The changes in the other platforms are not complicated, its about being able to disable certificate check mainly so I don't think they should fail. As of now SqueakSSL-Tests show 14 run, 3 passes, 8 expected failures and 3 errors on my Mac. The errors still left are: testSSLSockets, testSocketAccept, testSocketConnect. AFAIK all these try to use a test certificate and Accept - and *that* I haven't implemented on Mac (well, ok, I started - there is a way to at least set a Mac test cert into the plugin - but I didn't go further). New methods in the classes: SqueakSSL,SecureSocketStream>>certVerify: aBoolean Now one can tell the plugin to verify certs or just skip that. SqueakSSL,SecureSocketStream>>logLevel: anInteger Now one can set the logLevel in the plugin, 0 or 1 so far. Attached ssl-fix.zip which contains: . âââ platforms â âââ Cross â â âââ plugins â â âââ SqueakSSL â â âââ SqueakSSL.h â âââ iOS â â âââ plugins â â âââ SqueakSSL â â âââ sqMacSSL.c â âââ unix â â âââ plugins â â âââ SqueakSSL â â âââ sqUnixOpenSSL.c â âââ win32 â âââ plugins â âââ SqueakSSL â âââ sqWin32SSL.c âââ SqueakSSL-Core-gk.36.mcz âââ SqueakSSL-Tests-ar.17.mcz âââ ssl-fix.patch I threw in the latest SqueakSSL-Core and Tests that we have here at 3DICC. The Tests package is the same as on SS. The Core has 4 more fixes from Ron I think, just look in "History" to see commit messages there. ssl-fix.patch - this should show you what I have done in the platform files, and I produced it using git diff on those four files with this command: git diff 83bce99715cddd8a82c3d94c487e45ec0213be19 platforms/Cross/plugins/SqueakSSL/SqueakSSL.h platforms/iOS/plugins/SqueakSSL/sqMacSSL.c platforms/unix/plugins/SqueakSSL/sqUnixOpenSSL.c platforms/win32/plugins/SqueakSSL/sqWin32SSL.c > ssl-fix.patch The SHA is: commit 83bce99715cddd8a82c3d94c487e45ec0213be19 Author: Camillo Bruni <camillobruni(a)gmail.com> Date: Fri Nov 15 12:24:11 2013 +0100 fixed wrong path ------------------------------ ...phew. Ok, let me know if you need anything more and ask questions. regards, GÃ¶ran

100% CPU usage on image resume
by Holger Hans Peter Freyther Feb. 16, 2014

Feb. 16, 2014

Hi, I saved an image and today I wanted to resume it. Everything comes up, for a second I can interact with it (e.g. move a window) but then the pharo VM goes to 100% CPU usage. I let it run while writing this email and it eventually aborted: C stack backtrace: ./pharo[0x80a0c0c] ./pharo(error+0x19)[0x80a0f69] ./pharo[0x80785d3] ./pharo[0x80786e1] ./pharo[0x8078f10] ./pharo[0x8090d97] ./pharo(ceStackOverflow+0x6a)[0x80946ea] [0x76ef122e] ./pharo(interpret+0x7a6)[0x8094f36] ./pharo(main+0x2b3)[0x80a18b3] /lib/i386-linux-gnu/i686/cmov/libc.so.6(__libc_start_main+0xf5)[0xb74bb8c5] Smalltalk stack dump: 0xbfd5c610 M SmallInteger(Number)>negative 0x3841=7200 0xbfd5c630 M SmallInteger(Integer)>* 0x3841=7200 0xbfd5c64c M SmallInteger>* 0x3841=7200 0xbfd5c668 M Duration>asNanoSeconds 0x790ddef4: a(n) Duration 0xbfd5c684 M Duration>= 0x7fe004a0: a(n) Duration 0xbfd5c6a0 M DateAndTime>asLocal 0x7fe00488: a(n) DateAndTime 0xbfd5c6c0 M DateAndTime>- 0x7fe0040c: a(n) DateAndTime 0xbfd5c6dc M DateAndTime>asSeconds 0x7fe0040c: a(n) DateAndTime 0xbfd5c700 M DateAndTime>< 0x78d2a5f8: a(n) DateAndTime 0xbfd5c71c M DateAndTime(Magnitude)>> 0x7fe0040c: a(n) DateAndTime 0xbfd5c73c M TimerScheduler>fireTimers: 0x77ef49ac: a(n) TimerScheduler 0xbfd5c764 I [] in TimerScheduler>runTimers 0x77ef49ac: a(n) TimerScheduler 0xbfd5c780 M BlockClosure>on:do: 0x78d2a60c: a(n) BlockClosure 0xbfd5c7a4 M [] in Dispatcher>dispatch 0x77ef4764: a(n) Dispatcher 0xbfd5c7c4 M BlockClosure>ensure: 0x78d2a798: a(n) BlockClosure 0xbfd5c7f0 I [] in Dispatcher>dispatch 0x77ef4764: a(n) Dispatcher 0xbfd5c810 I [] in BlockClosure>newProcess 0x78d2a634: a(n) BlockClosure Most recent primitives stack page bytes 4096 available headroom 3300 minimum unused headroom 3508 (last object overwritten) Aborted TimerScheduler/Dispatcher is code of mine but I wouldn't understand why this code is getting blocked and would eventually cause a stack overflow? holger

DiskFileSystemTest testEntryAt
by Nicolai Hess Feb. 16, 2014

Feb. 16, 2014

Once I reproduced that error on a windows machine. It happens if pharos clock is behind the system clock. Creating a file results in a created tmestamp in the future. And comparing that time with "DateAndTime now" fails (now is smaller than the file timestamp). I couldn't find out, why pharos clock was behind, but somtimes this difference were several seonds.

Feb. 16, 2014

Hi, the classes in bootstrapped image have no layouts set. We must initialize them somehow because than class builder fails. Is there the code that did this task during Slot integration somewhere? Or can someone erudite tell us how to do that? Cheers, -- Pavel

Enhancement - single operation revert to last saved image
by Ben Coman Feb. 16, 2014

Feb. 16, 2014

Just a passing thought... as I am debugging, sometimes just before entering a step that I know is going to screw up the state of things, I save the image so that I can exit and restart to get back to that point. Now rather than having to manually quit & restart, a command "revert to last saved image" which did the quit & restart in one operation would be really nice. How doable would that be? cheers -ben
