The first is somewhat faster as no memory management calls are caused, but as Alexandre has pointed out, the current Wine code is at places quite stack intense which over time could lead to serious problems if Wine is extended with even more functions allocating much more Unicode buffers on the stack. So the question is really one about a little performance gain vs. code which has moderate stack requirements. Personally I think it is ok to allocate once a Unicode buffer on the stack in the high level API to convert ANSI to Unicode, provided the code path further down doesn't go back and forth between ANSI and Unicode conversions. But in general we should probably try in the future to get those buffers more often allocated dynamically for two reasons: 1) Just as a single buffer on the stack in a high level API once doesn't cause extreme stack usage, does the same single allocation of a buffer on the heap not cause a very noticable performance hit. 2) With proper dynamic buffer allocations we can get rid of many buffer length limitations. A stack buffer is always fixed length and can fail fataly if a parameter is entered which causes buffer overflow. So the code needs to do extra checks. Dynamic allocated buffers can be as long as necessary and do not necessarily have buffer overflow issues.

Clipboard between applications
by Ferenc Wagner March 24, 2003

March 24, 2003

Hello! I'm unable to move the contents of the clipboard between applications. At the end you find an annotated --debugmsg +clipboard log (with a call for IsSelectionOwner inserted into CloseClipboard). In short, the copying application can read the clipboard, but the other one can't. Seems like the x11drv/clipboard.c data isn't shared between the threads. Copying between two notepad.exe.so-s works, but through the X selection only (guess from the logs; the IsSelectionOwner status is 1 (ie. S_PRIMARY) during that process). Is it a mis(configuration|understanding) on my side, or isn't this functionality implemented?

#1336: Delete a read-only file says not found
by Sylvain Petreolle March 23, 2003

March 23, 2003

Trying to delete a read only file with wcmd actually should fail, option is not yet implemented. But it fails abnormally : it says that the file isnt found. A first test is done to see if no handle can be obtained, it passes. If I enable the --debugmsg +file it returns a GLE 2 fault. (file not found).

Well, it certainly wouldn't be a stretch for me to post news items. Generally I write the news section as items occur during the week. It's not like I sit down on Thursday night and bang out the whole WWN - all I do is run some scripts and mail it off. So yeah, I guess I'm volunteering for this. You'll just have to trust my judgement on what gets added and what doesn't. (Yeah, I'll be more liberal than I mentioned earlier.) It won't be complete duplication of WWN articles, though knowing the current state of development I'd guess there would be about 2 - 3 news items a week. My one request is Jeremy would have to write some kind of simple interface in order to get the items in there. I don't have reliable access to CVS or a shell acct at work, just web and email. I guess there's only three things that would need to be input: headline link to the real article / web page / press release short tagline (such as "WHAT'S NEW" for the releases) > Now, if we had a volunteer PR person that was coordinating and > driving PR for Wine, and *that person* wanted and was willing > to maintain and keep fresh such a section, then I would > be persuaded. right.. that wouldn't be me.

wine server and services ...
by Lars Segerlund March 23, 2003

March 23, 2003

Would it not be possible to launch wineserver to handle NT services ? Thus if the user was logged in services would be running ( if he fx. had started wineserver in his .xsession file ). I do realise that there are issues such as privileges and multiuser, but this would circumvent them would it not ? I have looked at some of the other things people have written about services, but this looks doable. / regards, Lars Segerlund.

If you're talking of consolidating the "Latest Release" and "News" headings, then I really don't care. I think one of the primary goals of WineHQ should be to put the software into the hands of users, and anything that makes that easier furthers the goal. Separating out the "Latest Release" and having two different download pages for "Binaries" and "Source" seems to do that. It definitely draws attention to getting the software. I think what you're getting at for news is we could (and should) announce things like: http://www.franksworld.net/wgm/ Hopefully in the future there will be more things like that. However, I'm definitely against announcing things like this: http://www.codeweavers.com/about/press_releases/?id=20030113 http://www.lindows.com/lindows_michaelsminutes_archives.php?id=4 http://www.xandros.com/release6.html None specifically mentions "Wine", however that's clearly behind their product. So at what point do you draw the line? Trust me, it's a pain in the ass to figure out. For WWN I'd rather err on the side of covering anything vaguely related to Wine, for the front page of WineHQ I don't think you want things like that, nor do you want to pick and choose what press releases get added. However, to confuse things, I think things like this definitely qualify as news: http://www.musicmatch.com/info/company/press/releases/?year=2001&release=2 So maybe here's the rule: if the primary business of your company is Wine development (TG, CW), or Wine is a core technology (Lindows.com) the most press you're going to get on WineHQ is from WWN. However, if you've utilized Wine to some how add value to a new or existing product then we'll announce it on the front page, at least the initial release. Just putting the word "Wine" in your press release doesn't count either way. --------------- Brian Vincent Copper Mountain Telecom vincentb(a)coppercolorado.com
