Behavior of SHChangeNotify
by Jay Yang 25 Jun '11

25 Jun '11

To try to implement copy-paste for shell folders, I used SHFileOperation for the actual copy. SHFileOperation calls SHChangeNotify to notify listeners about changes to the file system. But I noticed that the shell view would not update correctly if it was at 'C:\' but it would if it was at '/home/user_name/.wine/drive_c/'. In the end I traced this to the fact that in the first case the shell view calls SHChangeNotifyRegister with a pidl of the form <Desktop|My Computer|C:> while SHFileOperation is using SHChangeNotify to send a notification to those listeners registered on pidls of the form <Desktop|/|home|user_name|.wine|drive_c>. This makes it such that the shell view doesn't always get the notifications it expects. I can think of a couple of ways to fix this. 1. Have SHChangeNotifyRegister normalize all file system pidls to ones rooted in the unixfs. 2. Have the shell view register on a unixfs pidl. I would like to know if either of these is a good solution, or if there are better solutions. I can also write a quick test to demonstrate the problem if necessary. -- Jay Yang

usability study: "30 days with Ubuntu" author had trouble with wine
by Dan Kegel 25 Jun '11

25 Jun '11

http://www.pcworld.com/businesscenter/article/231065/ubuntu_linux_day_23_wo… First problem - ubuntu's package manager is unclear: "I opened up my handy-dandy Ubuntu Software Center and typed Wine in the search field, and...WTF? There are 14 matching items that show up. Many of them are variations on 'Microsoft Windows Compatibility Layer'. One has '(meta package)' at the end, another has '(dummy package)'. They each have a little sub-title like 'wine', or 'wine-gecko', or 'wine1.3-gecko'. Why isn't there just a single app clearly called 'Wine'? I didn't really have any clue which of these various software packages is the real Wine, but the one at the top--the 'meta package'--had the most ratings and ranked highly at 4.5 stars, so I decided to give that one a shot." Second problem - he expected to run a program called Wine, found wineconfig, did something with it, and then got back on track: "Once it completed installing, I went to the Applications lens on the Unity bar and typed in Wine. It claims I have three apps installed that fit that description: Configure Wine, Uninstall Wine Software, and Winetricks. I was hoping to actually run Wine, but given these three options it seems that Configure Wine is the logical first choice. I clicked Configure Wine and the Wine Configuration console popped up (go figure). At the bottom of the Applications tab, it specific which version of Windows to emulate...I mean be compatible with. It defaults to Windows XP, but I changed it to Windows 7... OK. Now, I am ready to run some Windows software, right?" Third problem: he expected Office 2010 to install and run Fourth problem: he couldn't even run the installer: " I opened up the folder from my Windows drive where I store downloaded software, right-clicked my Microsoft Office 2010 installation executable and clicked 'Open With Wine Windows Program Loader', and...got an error message. Something to the effect that this software is not marked as executable. Windows logoRunning Windows software in Wine proved convoluted and elusive.I checked with Google, and found a helpful walk-through from Psychocats.net called Using Wine on Ubuntu. Apparently, the fact that the software is an EXE is not obvious enough, so I have to first right-click the file, go into the Properties, and click a checkbox designating the file as executable. Seems convoluted. The problem is, every time I click the checkbox my check disappears. It won't let me make my file executable. I tried looking for more help on Google to no avail. I tried a couple other executable installation files, but couldn't mark those as executable either. I assume it is a permissions thing--like I need to somehow access the file permissions with root privileges in order to be able to make those changes. That is just a theory, though. So, no Windows software running for me just yet." Ouch, ouch, ouch.

Hi, While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

shouldn't the 1.3 dependencies include binfmt-support and lib32nss
by Susan Cragin 24 Jun '11

24 Jun '11

Just wondering. apt-get build-dep wine1.3 does not load binfmt-support and lib32nss... Installation of natspeak requires them. The installation script tries to grab them but failed for me.

Here's some light reading for your weekend enjoyment. I found this on Ars Technica and thought it was a pretty good summary of some stuff from Microsoft's past and a pretty good guess at how some future technology pieces fit together. http://arstechnica.com/microsoft/news/2011/06/windows-8-for-software-develo… -Brian

How to do single-step debugging while testing?
by Michael Mc Donnell 24 Jun '11

24 Jun '11

Hi I'm trying to figure out how to single step through the code. I've looked at the winedbg and gdb information on winehq, but still can't figure out what to do. I normally run tests by issuing: $ ../../../tools/runtest name_of_test Is there a way to run the test in a debugger, so that I can single step through the functions that the test calls? Thanks, Michael Mc Donnell

re: [1/3] cmd/tests: Use plain strings instead of char arrays for keywords
by Dan Kegel 24 Jun '11

Frédéric Delanoy wrote: - static const char escaped_space[] = {'@','s','p','a','c','e','@','\0'}; + static const char *escaped_space = "@space@"; I'm not sure it's worth the effort, since eventually we want cmd to use unicode internally, at which point we'll have to go back to using arrays.
