cannot write to the changes file
by Ben Coman March 13, 2018

March 13, 2018

Before creating an Issue, can someone confirm the following behaviour on Windows 10 ? Downloaded and unzipped into the same folder... * http://files.pharo.org/image/70/Pharo-7.0.0-alpha.build.425.sha.eb0a6fb.arc… * http://files.pharo.org/vm/pharo-spur32/win/pharo-win-i386-201711262336-8879… The directory contains... Pharo7.0-32bit-eb0a6fb.image Pharo7.0-32bit-eb0a6fb.changes Pharo.exe Double-clicking Pharo.exe produces notification... Information Pharo cannot write to the changes file named C:\Users\....\pharo\Pharo7.0-32bit-eb0a6fb.changes. Please check that you have write permission for this file. You won't be able to save this image correctly until you fix this. However if I edit to AST-Tests-Core > NumberParserTest >> testFail to add "My Comment" then close all windows, Save&Quit the Image, restart Pharo by double-clicking on Pharo.exe, and open System Browser on testFail I can see my comment. I'm not clear on exactly how it works but I presume that restarting the Image would require "My Comment" to be read from the changes file, but notepad shows its not in the changes file. So perhaps the error notification is part of a transition in-Image sources and nothing to worry about? cheers -ben

Pharo 7.0 does not includes "Metacello support for GitFileTree metadata-less mode"
by Juraj Kubelka March 12, 2018

March 12, 2018

Hi, In the following email [1], Dale Henrichs explains that there was an update to support correctly GitFileTree metadata-less mode. While I can see the mentioned class MetacelloCypressBaselineProject in Pharo 6.1, I cannot find it in Pharo 7.0. Is it supposed to include the Metacello update to Pharo 7.0 too? Thanks!

FFI Struct Argument Pass By Value Fails on Mac 64 bit
by Todd Blanchard March 6, 2018

March 6, 2018

I've been trying to track this down for a couple weeks now. I have concluded that structs passed by value to functions on the 64 bit VM are not properly populated. The struct's memory is all zero'd. I found this while trying to work with LibClang and found that functions that fetched code locations from code ranges always returned invalid zero'd locations. After spending some time with lldb I have traced the problem into the native code and found that the argument is not correct. I've carved out the wee bit of clang to reproduce this in a tiny library. The gist of it is below and the entire file is included. Basically the struct passed to the function clang_getRangeStart is zero'd memory regardless of the data I send from the image side. The build command I used on sierra is clang -shared -undefined dynamic_lookup -o microclang.dylib microclang.c I'm stuck. The FFI64 plugin is way beyond my comprehension. // microclang.c typedef struct { const void *ptr_data[2]; unsigned int_data; } CXSourceLocation; /** * \brief Identifies a half-open character range in the source code. * * Use clang_getRangeStart() and clang_getRangeEnd() to retrieve the * starting and end locations from a source range, respectively. */ typedef struct { const void *ptr_data[2]; unsigned begin_int_data; unsigned end_int_data; } CXSourceRange; const char* first = "first_pointer"; const char* second = "second_pointer"; // return a fake range with non zero data CXSourceRange clang_getArbitraryRange() { CXSourceRange range = {0}; range.ptr_data[0] = (void*)first; range.ptr_data[1] = (void*)second; range.begin_int_data = 17; range.end_int_data = 24; return range; } // Actual clang function - range is always zero'd here despite having values in the image CXSourceLocation clang_getRangeStart(CXSourceRange range) { // Special decoding for CXSourceLocations for CXLoadedDiagnostics. if ((uintptr_t)range.ptr_data[0] & 0x1) { CXSourceLocation Result = { { range.ptr_data[0], nullptr }, 0 }; return Result; } CXSourceLocation Result = { { range.ptr_data[0], range.ptr_data[1] }, range.begin_int_data }; return Result; }

What is the best VM right now for the Mac? Where/how would one get it? I recently downloaded a fresh Launcher from CI which comes with CoInterpreter VMMaker.oscog-eem.2254 uuid: 4f2c2cce-f4a2-469a-93f1-97ed941df0ad Jul 20 2017, but get.pharo.../vm70 downloads CoInterpreter VMMaker.oscog-eem.2265 uuid: 76b62109-629a-4c39-9641-67b53321df9a Aug 27 2017â¦ ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

Iceberg workflow
by Ben Coman March 3, 2018

March 3, 2018

I'm still struggling with Iceberg workflow for a personal repo. World menu > Iceberg Clicked <Clone Repository> Remote URL <-- git@github.com:bencoman/libclang-pharo-bindings.git Clicked <Create Repository> So now I have a new row... Name = libclang-pharo-bindings Current Branch = master Loaded version = No package loaded Status = Not loaded but nothing loaded into Image, which seems expected from Iceberg Operations Overview... * http://forum.world.st/Iceberg-operations-overview-td5036218.html (even though "Clone" is not shown there, I guess its the same as "Checkout") but I can't work out how to load it. In the filesystem I see the repo has been checked out, under... /home/ben/Pharo/images/latest-64-02/pharo-local/iceberg/bencoman/libclang-pharo-bindings Now from Iceberg Operations Overview, I guess I need to either load, merge, reload or pull. These all are apparently exposed in the UI. Right-clicking on the repo, the only one I see is "Pull incoming commits" and... Pharo quietly exits, with no debug log. Restarting to gather more info, after selecting the repo, the [Packages] tab is empty (maybe that is normal). Then I try Right-click>Refresh Repository with no effect. Right-click > Synchronize Repository takes me to three tabs with empty list views. The [Update] tab has a <Pull> button which also causes Pharo to exit. Versions... Ubuntu 16.04-64bit Pharo-7.0+alpha.build.300.sha.f81891fbde76d6a92e2827229293cb377d3b2c1c (64 Bit) Unix built on Aug 27 2017 20:00:40 Compiler: 4.6.3 VMMaker versionString VM: 201708271955 cheers -ben

[Request for comment] Hermes package
by Torsten Bergmann March 2, 2018

March 2, 2018

... to all participating authors of the Hermes package: PLEASE COMMENT YOUR CLASSES SO WE CAN CLEAN UP AND PREPARE A POLISHED PHARO 7 RELEASE So many uncommented classes in there today... We can do better and we should. I dont ask for detailed documentation but a single comment why the class is there or what it should care about is often already enough. If you have time to write code then you also have the time to write a simple class comment! So please do you homework (which is a general request to authors of other packages as well) Bye T.
