While this glibc question is slightly offtopic here, I think that maybe a few people on this list could be interested in glibc, since the subject comes back on a regular basis... the following web page : http://sources.redhat.com/glibc is definitely the place to go. I feel that maybe this information could help someone, since I have wasted more than one hour searching www.gnu.org for the glibc mailing list archive :-) Also http://www.suse.de/~aj/Projects.html#glibc where it's said that Andrea Jaeger is responsible for glibc bug reports. Reading the archive gives me the impression that the whole glibc is written by no more than half a dozen programmers, btw. What's more, I have also the impression that these few are not even contributing full time to glibc :-/ Gerard

Problem with 'GetPrivateProfileString'
by Lionel Ulmer July 18, 2001

July 18, 2001

Hi all, I have an installer crashing in 'GetPrivateProfileString' because of an NULL section pointer : 3 0x40076161 (GetPrivateProfileStringA+0x31(section=0x0, entry=0x40391efc, def_val=0x4039a394, buffer=0x403b0410, len=0x3e7, filename=0x4039a4e8) [profile.c:1232] in libntdll.so) (ebp=40586748) When looking at the code, there is the following comment (and code) : /* * undoc_feature means: * return section names string list if both section and entry are NULL. */ (...) if ((undoc_feature) && (section == NULL) && (entry == NULL)) /* undocumented; both section and entry are NULL */ But if I look at the entry for 'GetPrivateProfileString' in the MSDN, I get this : pAppName [in] Pointer to a null-terminated string that specifies the name of the section containing the key name. If this parameter is NULL, the GetPrivateProfileString function copies all section names in the file to the supplied buffer. lpKeyName [in] Pointer to the null-terminated string specifying the name of the key whose associated string is to be retrieved. If this parameter is NULL, all key names in the section specified by the lpAppName parameter are copied to the buffer specified by the lpReturnedString parameter. This is not in sync. with what Wine does.... It seems that only pAppName needs to be NULL to return a section name list. And there is another behaviour not done by Wine yet : copy all the keys of a section to the output buffer. So who is the author of this 'undocumented' feature in the Wine code ? Do you all agree that I should code it according to the (now) documented feature ? Lionel -- Lionel Ulmer - http://www.bbrox.org/

This is more a limitation of the malloc implementation than an actual bug. malloc uses brk() to allocate memory, but brk() cannot grow past an mmapped area, so malloc fails. With a standard Linux app shared libraries are mapped high in memory (usually from 0x40000000) so the malloc limit is about 1Gb; but if stuff is mapped lower, malloc capacity is reduced. The reason it works for mallocs larger than 128Kb is that glibc uses anonymous mmaps to reserve space for these instead of brk(). All in all, it's probably one more good reason for avoiding malloc in Wine. -- Alexandre Julliard julliard(a)winehq.com

Announcement : SynCE project
by Ludovic LANGE July 18, 2001

July 18, 2001

Hello, First of all sorry for the intrusion, but I think this may be of interest for some of you. SynCE project's ambitious goal is to provide a mean of synchronising handhelds devices with a (desktop) computer. By handheld, we mean any portable / embedded / PDA.... device, that needs to synchronize its data with a less mobile computer. (An exemple would be any PDA/PocketPC running Windows CE, or any PDA running Linux, etc...) The first step of this project is to provide a full (client & server) implementation of Microsoft's RAPI protocol, which is the low-level protocol used in ActiveSync synchronisation. This will allow, when completed : - a Windows CE device to communicate with any (non-Microsoft) computer, - A Linux device to communicate with a Microsoft computer and benefits from the existing tools, - etc, etc... The second step will be to provide a set of tools to synchronize data with 'standard' open or closed source application : Mozilla, KMail, etc.... Right now, the project is in its early, early stages ( we don't even have an alpha release ! ), but yet there are some bits that allow an implementation of the client part of the RAPI protocol, to query informations (registry, filesystem, databases,...) from a WindowsCE device. One tool (DBBackup) allows a full dump of the databases of the device. I won't interfere more with the list, and I invite all people interested to have a look on the project page ( http://www.sourceforge.net/projetcs/synce & http://synce.sourceforge.net ) and to subscribe to the mailing-list. We currently are looking for developper, and for testers having mobile devices still under Windows CE (PDA, PocketPC, etc...) and an unix-like desktop environment. Best regards, Ludovic LANGE
