pharo64+load code=broken image

by Javier PimÃ¡s

Hi folks, I take a fresh Pharo6.1 (spur64), load a git repository and save the image. When reopening I get a segmentation fault. OS is ubuntu 17.04/64 bits. I just cannot make it work, tried with all the vms I could (vmI61, vmT61, vmLatest70, vmTLatest70). I suspect it is related to using git but I'm not even sure. Below I put the involved code, crash dump at the end (seems to be the same with any vm). btw, the vmILatest70 script does not seem to work (curl https://get.pharo.org/64/vmILatest70 | bash).

Now I notice... the Linux PharoLauncher download is a ZIP file and the Mac PharoLauncher download is a ZIP file so... can we make the Windows PharoLauncher download a ZIP file? Doing that, at least as an interim measure, would *immediately* make PharoLauncher usable to students on locked-down Windows machines in University student labs. I'd expect this will improve the success with this experiment to use PharoLauncher as the main user entry point. The problem with using an "Installer" for the Windows PharoLauncher is the large amount of testing required to work *reliably* with *all* the "different ways people work" under several different versions of Windows introduced different layers of user security intricacies. Lets move forward in small steps. A ZIP download/extract is simple, and consistent with other platforms. In the meantime while waiting for that to happen, you can... 1. Download/extract http://files.pharo.org/platform/Pharo6.1-win.zip 2. Rename Pharo6.1 folder to PharoLauncher Rename Pharo6.1.* files to PharoLauncher1.1.* 3. Metacello new smalltalkhubUser: 'Pharo' project: 'PharoLauncher'; configuration: 'PharoLauncher'; load. PhLDeploymentScript doAll. PharoLauncher open. Smalltalk snapshot: true andQuit: true. 4. Zip up the parent folder, test on another machine and provide a link to your students. cheers -ben P.S. I was going to suggest also renaming Pharo.exe to PharoLauncher.exe but with an empty Documents\Pharo\vms I get... "Error: Cannot detect Pharo executable in C:\Temp\MyPharoLauncher\PharoLauncher" in PhLVirtualMachine>>initializeOn: "File @ C:\Temp\MyPharoLauncher\PharoLauncher" since "executables := aFolder allChildrenMatching: self class executableName." is empty since "self class executableName" ==> "Pharo.exe" It would be nice for that to not be hard coded. I tried digging further but ran out of time. I am curious it mattered since using "Pharo.exe" the Launcher went on to download a VM anyway. P.S.2. I believe the best path forward for system-wide PharoLauncher installed under "C:\Program Files" would be to install there only... * the VM * PharoLauncher.ZIP * a tiny non-Pharo wrapper program as the shortcut linked from AllUsers > Start Menu > PharoLauncher that extracts PharoLauncher.ZIP to the user's data area and then starts that user specific PharoLauncher. Then regardless whether: * they individually download/extract PharoLauncher.ZIP * the system-wide-wrapper extracts PharoLauncher.ZIP its a similar experience for users which should aid reliability by reducing the number of "different " use cases.

Re: [Pharo-dev] Pharo-dev Digest, Vol 59, Issue 25

by Richard Uttner

Interesting ... so I started guessing and searching a bit, guided by the idea that the guy is more experienced with JavaScript than with Smalltalk. What I found: In JavaScript there is an (incredibly beautiful) unary plus operator performing a Number cast on the object following. Being not shure that the value returned from the configuration call would be an Integer, he or she tried to cast it using the same unary operator, which did not work out of the box in Pharo ;) but could be fixed with a 0 as receiver. So I guess / think the intention behind was totally different compared to what it looks like for us. It's not very important here, but in general, guessing the effective intention behind some weird code you have to fix - that's the really hard part, but might save you a lot of time!
