If it turns out error is not changed on NULLs, it's easier to return early from SHFree or CoTaskMemFree than fix all places where those are used.

Make a 16-bit test in wine for krnl386.exe16
by Bruno Jesus Nov. 30, 2015

Nov. 30, 2015

Hi all, I'm trying to create tests for GetPrivateProfileString16 but it is not working as expected because the test is calling the kernel32 version of the function instead of the krnl386.exe16. Is there any way to make a test that compiles and runs against krnl386 instead of kernel32? I tried a few different things and the attached patch is the last attempt (the tests are wrong but that is not the point yet). Any help is appreciated, thanks in advance, Bruno

Learning to Develop for the Wine Project
by David Reinert Nov. 30, 2015

Nov. 30, 2015

Hello Friends, I am a current undergraduate senior Computer Science major looking to become familiar with and contribute to Wine. I just want to make sure I am doing all the best things I can do to familiarize myself with the project. I have over 3 years of experience coding in C/C++ and I have taken a course in Operating systems, but my familiarity with any MS-DOS/Windows based OS(DLLs, etc.) is next to none and I understand that the learning curve for Wine development is very steep. I've started by reading through the Wine Developer's Guide Wine Architecture section to try and gain an understanding of how the whole process operates. is this useful? Is there anything else that anyone would recommend I do to gain to good understanding of the project or should I just start writing patches and dive in head first? Any and all suggestions are welcome and Iwould appreciate any advice. Thanks, David Reinert

Wine devel packages ready for testing
by Michael Müller Nov. 30, 2015

Nov. 30, 2015

Hi, at WineConf we discussed about providing binary packages and the idea was that Sebastian and I take care of this, since we already build packages for Wine Staging. We now altered our build system to work in a more general way and you can now try out the first packages. We already tested them shortly, but since we do not use all those distros on a daily basis, we might still have missed something. Before I tell you the distribution specific installation instructions, first a more general overview about how the packages work. There are already a lot of different Wine packages out there, so our goal was to choose names which are not yet used on any system. To keep the risk of name collisions as small as possible, we decided for the following approach: winehq-devel winehq-staging These are the names of the packages which are most suitable for average users. The package will provide programs in /usr/bin (or some other distro-specific default installation path) and provide all the usual wine-specifc commands, like "wine", "winegcc", "wineserver", ... and so on. It will also contain the manpages, and desktop files. In the background, those packages do not really contain the binaries but instead pull in additional dependencies, on Debian/Ubuntu the "wine-devel" package and on Fedora/Mageia the "wine-development" package. Those packages install wine in /opt/wine-devel. On the one hand this makes clear, that its not a distribution provided package, as all files reside in /opt, on the other hand it gives much more flexibility. A user can now decide whether to install the winehq-devel package, which symlinks all files to their usual locations in /usr/{bin, share} etc. or whether he wants to install multiple wine versions at the same time by using the underlying wine-devel/wine-development package. Besides the possibility of having multiple wine versions installed at the same time, this way we could even ship additional dynamically linked libraries without messing around with the rest of the system, for example if distribution packages are incompatible with wine. Below are the instructions how to install those packages on various distributions. Executing wine --version (or /opt/wine-devel/bin/wine --version) should afterwards show 1.8rc-1. If you find any bugs, please report them so that we can fix them. You can also take a look at the packaging files at https://github.com/wine-compholio/wine-packaging (or send a pull request if you want to contribute with your improvements). In case everything is working fine, we should add those packages on the download page, so that more users can try out the release candidates for 1.8. So, as a short summary, about what is already working, and what still needs to be done: - We'll now be able to provide 8 Ubuntu, 8 Debian, 4 Mageia and 2 Fedora packages per release (which means about 44 build tasks per week). - Fedora 23 packages are still missing, but will be added soon. - Crosscompiled Mac OS X packages will also be added soon. - Additional distributions can be added on request - but please try to contact your distribution first! ---- Ubuntu ---- # Add repository sudo add-apt-repository ppa:wine/wine-builds # Update packages sudo apt-get update sudo apt-get install --install-recommends winehq-devel # Advanced users can instead install the wine-devel package # directly, in parallel to their regular Wine versions. ---- Debian ---- # Enable 32 bit packages sudo dpkg --add-architecture i386 # Install key which was used to sign packages wget https://dl.winehq.org/wine-builds/Release.key sudo apt-key add Release.key # Add repository to /etc/apt/sources.list or create a *.list # under /etc/apt/sources.list.d/ with the following content: deb https://dl.winehq.org/wine-builds/debian/ DISTRO main # with DISTRO being either wheezy, jessie, stretch or sid # Update packages sudo apt-get update sudo apt-get install winehq-devel # Advanced users can instead install the wine-devel package # directly, in parallel to their regular Wine versions. ---- Fedora ---- # Currently only Fedora 22 is supported, 23 will be added soon # Add repository dnf config-manager --add-repo https://dl.winehq.org/wine-builds/fedora/22/winehq.repo dnf apt-get install winehq-devel # Advanced users can instead install the wine-development package # directly, in parallel to their regular Wine versions. ---- Mageia ---- # Install key which was used to sign packages wget https://dl.winehq.org/wine-builds/Release.key sudo rpm --import Release.key # If you are using Mageia 4 sudo urpmi.addmedia "WineHQ 32-bit" https://dl.winehq.org/wine-builds/mageia/4/i586/ # If you are using 64-bit Mageia 4, also add sudo urpmi.addmedia "WineHQ 64-bit" https://dl.winehq.org/wine-builds/mageia/4/x86_64/ # If you are using Mageia 5 sudo urpmi.addmedia "WineHQ 32-bit" https://dl.winehq.org/wine-builds/mageia/5/i586/ # If you are using 64-bit Mageia 5, also add sudo urpmi.addmedia "WineHQ 64-bit" https://dl.winehq.org/wine-builds/mageia/4/x86_64/ sudo urpmi.update -a sudo urpmi winehq-devel # Advanced users can instead install the wine-development package # directly, in parallel to their regular Wine versions. ------------------ Regards, Michael

Can you tell me more about the open tool used for signing Mac OS X executables? I have been working on font signing in the recently open-sourced microsoft font validator (there is an official windows-only tool for signing fonts, but apparently an open-toolchain based tool also exist in somebody's hard disk) That although is part of an ISO standard for fonts, borrows heavily from microsoft's authenticode excutable signing infrastructure.
