dlls/msvcrt/time.c picks up wrong CLOCKS_PER_SEC define
by Uwe Bonnes Sept. 6, 2004

Sept. 6, 2004

Hallo, wine/include/msvcrt/time.h defines CLOCKS_PER_SEC conditionally: #ifndef CLOCKS_PER_SEC #define CLOCKS_PER_SEC 1000 #endif in wine/dlls/msvcrt/time.c, <time.h> is included and defines CLOCKS_PER_SEC unconditional before to 1000000l. So MSVCRT_clock returns a value 1000 times to high. How should this be fixed? Should wine/dlls/msvcrt/time.c do the define unconditional? Do we need to use a different define (e.g. MSVCRT_CLOCKS_PER_SEC) in MSVCRT_clock()?

I posted it as a bug at > http://bugs.winehq.org/show_bug.cgi?id=2385 . If you can add something > about the coding style I can fix it up and repost it for inclusion. A few things that jump out at me (not really reviewed the code itself): - No C++ // style comments, I'm afraid. They aren't portable enough. - Use HeapAlloc() over malloc(), as it says in the cheatsheet - Are you sure there is a debugstr_a?? I can't think what it would do, ANSI strings can just be printed by regular printf - You have to declare all the variables at the start of a block. Yes, it's a pain. Another C portability rule. So, can't do this: LPSTR foo = bar; StrCpyA(a, b); int i; They all have to go at the top. - Minor stylistic note: you can use strcpy rather than StrCpyA. But I doubt this was a problem. - Usually best to space stuff out, ie rather than this: if ( temp_out == temp_out2 ) { temp_in += 3; continue; } use this: if ( temp_out == temp_out2 ) { temp_in += 3; continue; } ... again I doubt Alexandre would reject the patch because of this. - //if ( *temp_in == '.' ) ... wine code generally doesn't do this. If you find it hard to match up a closing brace with the statement that opened it maybe you need ... *fanfare* EMACS! :) - Is it possible to implement the ANSI version by converting to unicode then calling the wide version, rather than duplicate it? The rest looks fine, I expect it was just the C portability stuff that tripped you up. Please do try again! thanks -mike

Possible fun project/todo list item?
by Mike Hearn Sept. 6, 2004

Sept. 6, 2004

The OpenSSL library we use in wininet/netconnection.c is a very unstable library, with somewhat odd licensing as well. By unstable I'm talking about the interfaces it exports: unfortunately they break backwards compatibility very frequently with the result that a build of Wine compiled on one system may bail out when using SSL on another, as the soname/abi of OpenSSL it's looking for has changed *yet again*. This also means that some distros deliberately ship older versions and just backport security fixes, as upgrading OpenSSL to newer versions is quite painful. Fedora at least does this. If anybody is looking for work to do then, addressing this problem may be useful. Probably the best way forward is to talk to the GnuTLS people (http://www.gnu.org/software/gnutls/gnutls.html) and see if you can get written confirmation from them that they have a strong commitment to binary compatibility (at least, more than OpenSSL does). It also seems to be a fairly stable project: the new maintainer is more focussed on portability enhancements and a slow release cycle than making huge changes to the code. If so, it might be worth porting wininet over to GnuTLS, or alternatively, rather than remove the OpenSSL code just add code to use GnuTLS and then fall back to OpenSSL if it cannot be found (or vice-versa). One interesting thing about GnuTLS is that it has some OpenSSL compatibility code, but from a look at their website it seems that this is GPLd. Maybe we could get an exemption from them. The downside is that while OpenSSL is frequently going to not be found as it's the wrong version, GnuTLS is also not widely installed by default so it might not get us much in the short term. The good news is that Gaim packages are often built against it, so in any modern distro that packages Gaim (which is a very popular chat client) in its repositories, there's a good chance GnuTLS is packaged as well. thanks -mike

Re: Wine and industrial communication like OPC
by Rickard Svensson Sept. 6, 2004

Sept. 6, 2004

Thank you, for all your answers! We have one employee who has worked a lot with Windows, and same with OPC. So I can provide same answers. * Mike Hearn - OPC is mostly used for data collection, and to a lesser degree to control industrial machines. * Juan Lang AND Robert Shearman - OPC doesn't use named pipes. OPC uses Dcom over TCP. * Mike Hearn - OPC doesn't need any new Windows (2000, XP) parts, and should work on Win 98 with the added Dcom support (not tested). * Mike Hearn - Price of OPC for Linux was when I looked at it for about a year ago 3000 - 4000$ per project you used their API in. And it only supported one of the OPC versions. Now I guess that the prices has been going down... Now I also got some questions from your answers: * Did I understand correctly. Wine doesn't have a built in support for DCom, to be abel to use Dcom I have to add the DCom support from Windows 98 to the Linux system? And the problem with that is the MS License, it stops me from distribute those XXX.dll with a Linux product (hardware and software in this case.) * We want to make a OPC server, because other computers want to get information from our system. Is there a problem in make a DCOM server, is it the "no user can acsas port under 1024 on a Linux system" problem. * What I have heard I thought DCom uset RPC??? But Juan Lang wrote that Wine doesn't have support for RPC /Rickard -- ___________________________________________________________ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm

It's a problem for lots of reasons. They add up to this: this is unimplemented in Wine, and probably won't be implemented any time soon. > * What I have heard I thought DCom uset RPC??? But > Juan Lang wrote that Wine doesn't have support for > RPC Did I? I certainly didn't mean it. But you'd need to install the DCOM98 update to have any chance of success at it for now, at least if I read the code right. --Juan __________________________________ Do you Yahoo!?
