Otto Frost commented on SYNAPSE-502:
------------------------------------
Hello,
The patch adds the use of a temprary file but it doesn't solve the problem.
The receiver typically fetches everything available on the directory "*" and
will therefore fetch the temp file as well.
It must be possible to specify the tempfile name to have a suffix or prefix
like "filename.tmp" assuming the receiver supports avaoiding reading files with
a certain prefix or suffix.
Alternatively it should be possible to place the tempfile in a working
directory like
"destinationDirectory/workdir/filename.tmp"
or (if receiver doesn't want subdirectory in dest dir)
"destinationDirectoryWorkdir/filename.tmp
> improve the vfs transport to use temporary file

> Enhance the vfs transport to use a temporary file at upload.
> The reason is to prevent the receiving application to start reading the
> uploaded-file (put) before it is completely written.
> Of course the temp file has to be on the same physical filesystem.
> This feature should work for ftp/sftp/local file/...
> It should be similar in funcitonality as what SAP XI has at the ftp/file
> adapter.
> See
> http://help.sap.com/saphelp_nw04/helpdata/en/0b/9a50465ccf84479e39a6d50c90fb3f/content.htm
> See the receiver file adapter (the system xi communicates with receives data).
> See the option TargetTempFileName
> If there is already this functionality, it would be good idea to include how
> to solve the problem in the examples. Of course the best solution is to use
> MOM, but sometimes that isn't an option.
