new cygnative version 1.2 (for rsync + plink)

An anonymous user reported a problem with cygnative's command line truncation.

I released the new version 1.2, that should not have this limitation.

[Update]
There is a newer version.

Илья Басин observed a bug, possibly restricted to some cygwin versions. Спасибо - thanks for reporting and testing!

I published the new version 1.1 with a workaround for this problem.

rsync does work with plink - part 2

Thu, 12 Mar 2009 20:51:48 GMT

<Update>
There is a new version with a bugfix.
</Update>

As I wrote in rsync does work with plink I tested a wrapper program to solve the invalid handle problem.

Now I make this program available (see Anhang). You may send me a note about your experiences or leave a comment here.

Cygnative.exe is a wrapper for cygwin programs which call native Win32 programs with stdin and/or stdout handle redirected. Without cygnative.exe it is possible that the native program can not read from the handle and receives a "invalid handle" error.

Usage:

cygnative <nativeProgram> [args...]

Example with rsync and plink:

rsync --blocking-io -e "cygnative plink -batch" -h -a 
--delete / user@server:/data2/backup/

rsync does work with plink

When I tried to use a tunnel via plink for rsync I got the error:

Unable to read from standard input: The handle is invalid.
rsync: read error: Connection reset by peer (104)

I wrote about the problem in rsync does not work with plink. Meanwhile I could investigate the problem. As mentioned in my previous blog entry the reason is an incompatibility in stdin/stdout redirection between cygwin and native Win32 programs.

To solve the problem I tried to use an other implementation to spawn a program in rsync. But this was not possible due to cygwin file descriptor handling shortcomings. But I was able to write a wrapper program for rsync, that avoids the wrong descriptor handling.

Now I'm testing this wrapper, the results are promising to have a working solution.

rsync, plink and zfs on FreeBSD

I thought I can report some news for the rsync/plink problem, but I spent some time on debugging. The reason was I did not realize that I walked into the zfs on FreeBSD trap.

I use a test partition with zfs for backup purposes and did not see any problems until today. With rsync the system showed the often reported hangs. So I need to test on an other partition. But there is hope to get rsync with plink running. :-)

rsync does not work with plink. It seems that there is an incompatibility in stdin/stdout handle redirection.
