problem about writeInBackgroundAndNotify
Hi everyone, I have downloaded the WebServer-1.2.1 example program from http://wiki.gnustep.org/index.php/WebServer. I got a problem. When the browser client visit the server page, like http://localhost, the server didn't give any response, until timeout. I checked the program, I found that if I change the "[[connection handle] writeInBackgroundAndNotify: result]" in Line 1480 to"[[connection handle] writeData: result]" it can work. Does anyone known why the method writeInBackgroundAndNotify cannot work in this example? ___ Gnustep-dev mailing list Gnustep-dev@gnu.org http://lists.gnu.org/mailman/listinfo/gnustep-dev

Are you using an up to date version of GNUstep? Not that the version of the libraries is likely to make any difference ... this code has been running 24*7 in high volume applications for years without any trouble. ___ Gnustep-dev mailing list Gnustep-dev@gnu.org http://lists.gnu.org/mailman/listinfo/gnustep-dev
Re: problem about writeInBackgroundAndNotify
Hi Richard Thank you very much for your answer. But I have tried it again at a different machine which also have Windows7 Build 7127 platform. All my computer have platform of Windows7, I don't test on any other environment. What about your environment? The program of GNUstep I used is downloaded from http://www.gnustep.org/experience/Windows.html, the latest stable version. It can reproduce the problem with any browser ( Firefox, Chrome ). I think the async socket function of GNUstep maybe have some problem on Windows7. 2009/8/22 Richard Frith-Macdonald > > On 21 Aug 2009, at 18:17, Guo Xu wrote: > > Hi everyone, >> I have downloaded the WebServer-1.2.1 example program from >> http://wiki.gnustep.org/index.php/WebServer.

I haven't noticed it in other programs, but I don't use windows much, in fact I don't have a windows development environment at the moment.

Re: problem about writeInBackgroundAndNotify
The behavior you described is exactly the same as me.I also tested it on Windows server2003, It seems all of the Windows platform have the same problem. 2009/8/23 Riccardo Mottola > Hi, > > > Richard Frith-Macdonald wrote: > >> >> On 22 Aug 2009, at 04:35, Guo Xu wrote: >> >> Hi Richard >>> Thank you very much for your answer. >>> But I have tried it again at a different machine which also have >>> Windows7 Build 7127 platform.

No, the client never received the response, the client gave up and it depended on the client how long it was. I see however that you committed some changes to base and now it works fine for me on WindowsXP.

Re: problem about writeInBackgroundAndNotify
Hi Richard I directly downloaded the GNUstep setup bin files from http://www.gnustep.org/experience/Windows.html page, I don't know how to apply this change to my environment. So I can't test if it is ok. Should I compile GNUstep environment myself?

Re: problem about writeInBackgroundAndNotify
Unless there has been a binary incompatible change to the library since the last release (which there has not, as far as I know), you can just get the latest base library from SVN (see: http://www.gnustep.org/resources/sources.html) or from the daily-snapshots and compile and install it: A. Start the msys shell (Start -> Programs -> GNUstep - Shell) B. Get SVN base (svn co http://://svn.gna.org/svn/gnustep/libs/base/ trunk) or daily snapshot (ftp://ftp.gnustep.org/pub/daily-snapshots/core.current.tar.bz2 ). unpack the snapshot and CD to the base library if necessary. C. Type: configure make install The new base library should overwrite the one that came with the bin files.

Thanks a lotI tested the problem, it works fine for me on Windows7 now.
