Dear rsync-developers,
on AIX5.1 with 32-bit kernel one can have large-file support.
rsync in principle supports it correctly since the flag
_LARGE_FILES is treated correctly in the /usr/include/*.h
But there is one point missing, the mkstemp is not opening
a large file. So syncing large files crash after 2GB.
To avoid this one could either put a
#ifdef _LARGE_FILES
#undef HAVE_SECURE_MKSTEMP
#endif
at the beginning of syscall.c or in rsync.h, or one could add a
&&!defined(_LARGE_FILES)
in line 154 of syscall.c
Best configure would not define HAVE_SECURE_MKSTEMP if
_LARGE_FILES is defined, because mkstemp is not secure
for large files. There is no mkstemp64.
I did not check, whether with a 64-bit-kernel the mkstemp
works properly, since I have no access to a machine running
AIX5.1 in 64-bit kernel-mode.
For replies, pleas reply directly, since I am not on the list.
With kind regards
Andreas Schott.
