Problem in FTP of Indy9

Hi all,

I got a problem while use IdFTP component to get binary file from a SUN
solrias 2.5 server. I found if the file contains char '$0A', which means
'new line descriptor', the IDFTP will automatically add char '$0D' before
every '$0A', even I have set the tranferType to be 'ftBinary'.

Does anyone here know about this issue?

Thanks in advance.

Peer

I had problems with Solaris too.  The size of the remote file always
came back as 0.  My FTP app worked fine with HP & other FTP servers,
but not SUN.

Some Team-B person wanted a directory listing to as to possibly
change the Indy code to parse the Solaris listing properly, but I
could not help as I had alredy left the coy. using the SUNs.

On the other hand, if I ignored the returned file size & transferred
the file anyway, it came through OK - no extra CRs added.

Wierd.

Rgds,
Martin

I would like to see the listing to see what can be done in Indy 10.

I always thaught Sun Soloris was simply a Unix operating system and
simply used the output of /bin/ls (that seems to be a de facto
standard).

There has been a backport of the Unix parser in Indy 10 to Indy in our
VCS already and that is available for Indy 9.  That might help matters
better.

Is it a problem of Indy?
I think so.
For example, if you get a text file from Solaris system, and if you set the
transfer mode of TIdFTP to be ftBinary, you will also find the Indy will
automatiaclly add char '$0D' before every char '$0A', because text file with
UNIX style has only char '$0A' at the end of every line. I think this
feature is used for format conversion between UNIX and Windows.

Does anybody know how to disable it?

No, its not. In Binary Indy does not do any altering of the output. NEither
does it in text mode.

Its up to the server to make the changes.

Indy does not modify the file transfers.

Re:Problem in FTP of Indy9


You mean it's the sever (SUN OS) that make these changes, but I tried to get
same file by using windows ftp command, it's fine, no any change was made.

And I use TIDTelnet component in my program to get a text file from same
server (something like: execute 'cat' command in SUN server, then echo all
output to socket), I also find same problem that Indy add char '$0d' before
every char '$0a'.

For a text file, it's acceptable to add a control char like '$0d', but not
for a binary file.

Hope more comments.
Thanks.

It depends on text or binary mode - and its up to the server if it does
anything.

Are you using Text or binary mode? In Binary indy changes NOTHING. In text it
might format it for Windows - I'd have to look.

Indy does not modify binary files - trace the source to see.

Re:Problem in FTP of Indy9


Because there was a bug when doing that, the bug caused all files to be
transferred in ASCII mode.

the changed file can be found on the vcs or here:
