validation error related to Fuel

by Christophe Demarey

Hi, With case #17889, I get the following validation error: Exception: FLMethodChanged: Materialization error. Method SystemSettingsPersistence class>>#initialize changed its bytecodes. I have no idea what to do with that. Yes, I changed this method and â¦ Does anyone have an idea? Thanks, Christophe

Hum, it seems to be a little error prone, would it not be interesting to merge layout params ? 1 class but several traits as you have already begun to do ? Do you have any ideas for implementing SVG support ? I found no way to implement it at the path level, so i think that we need a special shape to do that. But, having an SVG shape forces us to delegate the drawing to the shape because it is not the same drawing strategy as "normal" shapes.

Hi guys, I remember someone mentioning Esteban was writing a doc on some tips to migrate from old FFI to new UFFI of Pharo 5.0. Do you know where can I find such a doc? Thanks, -- Mariano http://marianopeck.wordpress.com

New Cog VMs available

by Eliot Miranda

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3663 CogVM binaries as per VMMaker.oscog-eem.1746/r3663 General: Fix loss of signals to e.g. a socket's readSemaphore when data available: Fix a bug in sqAtomicOps.h where the assumption that the intrinsic atomic add operation will apply to 16-bit variables is false on clang. So on x86 and x64 use inline assembly with gcc and clang since this is known to work. Improve the doSignalSemaphores code in sqExternalSemaphores.c so that the tide variables are initialized at the right point and so there's only one copy of the signalling code. Allow primitiveUtcWithOffset to accept an optional parameter with an array or object with two or more slots to store UTC posix microseconds and time zone offset in seconds. Compatibility with VMM trunk. Add a Smalltalk epoch version of it, primitiveUtcAndTimezoneOffset, and give it primitive #244. Fix signed/unsigned arithmetic issues in 64-bit microsecond clock code. This fixes the bug whereby Time localMicrosecondClock - Time utcMicrosecondClock // 1000000 would answer something with an odd second, a multiple of 3600 plus 1. General Integer conversion routines: Several clean ups to integer conversion routines. Simplify bit operations using positiveMachineIntegerValueOf:/ positiveMachineIntegerFor: rather than doing 32/64 bits dissertation. Spur Cogit: Rewrote identity primitive to check for forwarders only when the identity of objects is different. The previous version would crash if the argument was a forwarder to an immediate. Spur VMs: Now that UUIDs are created with purely image-based code in Squeak trunk, make the UUIDPlugin external in all Squeak Spur VMs. Plugins: Make FFI load symbol fail after (when find function fails). In Pharo, we allow to load global functions (so we can control world windows through FFI). LargeIntegersPlugin: Finish 1st round of LargeIntegers refactoring - simplify the left and right shift - use as much unsigned arithmetic as possible - homogenize type declaration within the plugin - remove unused digitOf:at: Slang: Beware: sending abs to an unsigned int will re-interpret the int as signed and will generate C compiler warnings. The new version uses SQABS and SQLABS macros on sqInt and sqLong vars, and fabs and fabsf on double and float args, respectively, and llabs on long long, __int64 vars. Mac OS X: Unswap the Squeak and Newspeak localized strings _,,,^..^,,,_ best, Eliot

Re: [Pharo-dev] [Bloc] A mobile device using Bloc

Aha! :) FrameLayout never worked so... It is on todo list after grid layout. Also there is a rule of how layouts and layout properties are bounded together: *All children of an element with XYZLayoutStrategy must have XYZLayoutParams.* It is allowed to have an element with ABC layout strategy and XYZ layout params.

Hi Alex, The alignment problem was a mistake, i just needed a "BlLinearLayout *vertical*" to allow horizontal alignment. I committed the BlMobileTests class which contains encountered issues. Warning, some tests crash the image...
