ObjectHeader has invalid reference count Errors

Hi all! When running AbiWord this is happening. Everything works, just more of these errors. I think the first clue is this next line, (subsys/win32k/m(subsys/win32k/objects/gdiobj.c:1289) Attempted to change owner isc/object.c:50) ObjectHeader 0x8D0E0140 has invalid reference count (-2) (subsys/win32k/misc/object.c:50) ObjectHeader 0x8D0E6808 has invalid reference c ount (-2) (subsys/win32k/misc/object.c:50) ObjectHeade ship of object 0x2304035f (pid: 0x12c) from pid 0x128!!!

The MSDN library says: If the function succeeds, the return value is the number of TCHARs stored into the buffer pointed to by /lpBuffer/, not including the terminating null character.

Re: [ros-diffs] [weiden] 16553: handle memory allocation errors in GetEnvironmentVariable() and ensure the string is always null-terminated

If it is, RtlQueryEnvironmentVariable_U() could succeeded even if a zero length buffer is passed in. And then, would we crash appending the NUL termination? Since GetEnvironmentVariable has to have a buffer of at least one character to succeed, maybe we should add such a guard to the top of the function... Thanks, Joseph

Console Csrss Handle Errors

by James Tabor

Hi all, Bored again, decided to build ros on ros. Getting this, (subsys/csrss/api/handle.c:75) CsrGetObject returning invalid handle (KERNEL32:lib/kernel32/mem/global.c:412) Memory Load: 11 (KERNEL32:lib/kernel32/mem/global.c:412) Memory Load: 11 (subsys/csrss/api/handle.c:75) CsrGetObject returning invalid handle (subsys/csrss/api/handle.c:75) CsrGetObject returning invalid handle Things I noticed may have been fixed, Multi cmd problem, handle count going throw the roof and hangs. Thanks, James

Something Completely Different!

by James Tabor

Hi! When compiling ros on ros this happens. The build process, well nothing has changed for more than a year, except cmd and the dlls. make[2]: Entering directory `C:/ros/reactos/apps/utils/rundl32' windres --include-dir ../../../include --include-dir ../../../w32api/include ru ndll32.rc -o rundll32.coff gcc -DUNICODE -Wall -Werror -D__USE_W32API -I. -I../../../include -I../../../w32 api/include -pipe -march=i386 -D_M_IX86 -c rundll32.c -o rundll32.o make[2]: *** No rule to make target `../../../dk/w32/lib/user32.a', needed by `r undll32.nostrip.exe'. Stop. I use a old build to test ros with. It gives ros hell and it is small too. Doesnt use much disk space. Thanks, James

Branch to 0.2.7 happened tonight

by Robert Köpferl

Hi a new branch ros-branch-0_2_7 * r16538 exists, now. Please be cautious in terms of to which branch you commit and that this branch remains buildable. The next days there will be a binary distribution as RC1 whilst RC2 or final will follow.

Re: [ros-diffs] [weiden] 16536: return the length of the string excluding the null-termination character on success in GetEnvironmentVariable(). Thanks to Hartmut.

by Joseph Galbraith

It seems like there is some uncertainty between this code and RtlQueryEnvironmentVariable_U about who is going to ensure that the string returned from GetEnvironmentVariable() is nul terminated... If I read the code in RtlQueryEnvironmentVariable_U correctly (and I don't swear I have), it is possible for it to return STATUS_SUCCESS and not copy a NUL terminator. This happens if the buffer is large enough to contain the value but not the NUL terminator. This is probably correct for this function since UNICODE_STRINGs (and the Rtl* library) generally have no requirement of a NUL terminator. But then, if I read the code in GetEnvironmentVariable() correctly, I don't believe it takes this situation into account. Probably, it would be best if RtlQueryEnvironmentVariable_U _never_ copied the NUL terminator, and the caller was always responsible for adding NUL termination, if needed. Thanks, Joseph PS. MSDN is slightly unclear (to me) on how it should behave in this case, but it seems unlikely that the real GetEnvironmentVariable() returns success and a non-nul-terminated string. But I haven't written a test program to prove it. weiden(a)svn.reactos.com wrote: > return the length of the string excluding the null-termination character on success in GetEnvironmentVariable().

Hi, I would like it, if 'make install' does always copy all files. - Hartmut
