It's a genuine misfeature in ext4 called auto_da_alloc which causes a flush on close if the file has been truncated (ftruncate or O_TRUNC) and the file size is zero bytes. I added these patches which work around the issue:

The way we used posix_fadvise was wrong, and yet right! Rich.

Add wrappers around posix_fadvise and use them in places we were calling posix_fadvise directly before. Also in virt-builder we were doing this (and ignoring the result): posix_fadvise (fd, 0, 0, POSIX_FADV_RANDOM|POSIX_FADV_DONTNEED); However the POSIX_FADV_* flags are _not_ bitmasks! In fact POSIX_FADV_RANDOM|POSIX_FADV_DONTNEED == POSIX_FADV_NOREUSE so we were giving a completely

More posix_fadvise stuff, and document what Linux really does with these calls. Also fixes a nasty bug in virt-builder. Rich.

v1 -> v2: The first patch is the same (the pure refactoring), but in the second patch I implement Eric Blake's suggested version. Rich.

This is largely a simple refactoring, but it combines another definition of this function from virt-builder which had a slightly different prototype. --- builder/pxzcat-c.c | 20 +------------------- daemon/daemon.h | 18 ------------------ lib/guestfs-internal-all.h | 18 ++++++++++++++++++ 3 files changed, 19 insertions(+), 37 deletions(-) diff --git a/builder/pxzcat-c.c

Hello - I am making a first attempt at writing a simple C++ routine to print out R objects (this is a simple proof-of-concept as part of a larger package development). The relevant C++ routine is as follows: void Rwrite(SEXP fd, SEXP msg) { int *ofd = INTEGER(fd); const char * omsg = CHAR(asChar(msg)); printf("[%i] %s",*ofd,omsg); } And the corresponding interface in R is as

Hello, Here is a quick patch so that pxzcat creates sparse files without fragmentation. It preallocates the file, then discards extents that weren't written. This relies on Linux syscalls.

If the source and destination file are identical, the receiving scp truncates the file. On the sending end, read() returns 0, and garbage is sent instead of actual data, and the receiving end puts it into the file, which at least confuses the users. -- Florian Weimer Florian.Weimer at RUS.Uni-Stuttgart.DE University of Stuttgart http://cert.uni-stuttgart.de/

Just like with index-parse.h, also index-struct.h is a dependency of index-parser-c.c which automake cannot generate correctly.
