FTPc 1.49

I’ve updated FTPc to preserve the timestamp when transferring files if the server you are connected to supports the MTMT and MDTM ftp commands. Note the timestamp of directories is not preserved.

I had always wondered why the timestamp was not preserved. My ISP had some sort of hacking problem as all my files got restored and now all have the same datestamp on their server so I can no longer see when they were last updated. Curses.

This is not to imply that there is any issue with the new !FTPc, for which many thanks, but pain needs to be reported somewhere. I don’t think I have seen pain at an unknown location before.

On running !FTPc 1.49 on an up to date Raspberry Pi Mk1 :-

Thats a lot of pain – means nothing to me. Do you have the same problem with 1.48?

Could have emailed me to save long posting on the forum.

I think he’s referring to zero pain.

still meaningless

Ah! Sorry to be obscure. See this news item or read about it in Archive magazine 23:12.

Thanks Colin

Thats a lot of pain – means nothing to me.

One extraneous item found its way into the list, now removed. I reported it here because, as I tried to say previously, it is not clear at this point that it is an FTPc issue at all. One item is clearly a bug in DDEUtils.

Do you have the same problem with 1.48?

Yes.

Ah I see now. ‘Unknown’ looks like its in ‘utility module’. So I just need to track down the function these code fragments are from.

The first 2 unknowns are in GSINIT and the 3rd unknown is in GSREAD. I can’t see that I’ve used either (or GSTRANS for that matter) so something must be calling it for me – possibly a ddeutils call but I’m not using one of them either.

possibly a ddeutils call but I’m not using one of them either

Good point what does DDEUtils have to with any of this! !FTPc doesn’t use it!

On a freshly booted Pi running !FTPc just results in the three unknown location pains. There is no DDEUtils in RMA!

DDEUtils appears when !Reporter, which has its uses in that it reports writes to the ZeroPain log file, is run. Then running !FTPc does provoke a pain in DDEUtils before the three unknowns.

Possibly demonstrating a total ignorance of the whole job I tried a *where for the R15s of the unknowns :-

*where fc01f5dc
Address &FC01F5DC is at offset &0001F5DC in the Kernel
*where fc01f618
Address &FC01F618 is at offset &0001F618 in the Kernel
*where fc01f670
Address &FC01F670 is at offset &0001F670 in the Kernel

Whilst I understand that you may not be able to date stamp a directory on an FTP server and that the date on an FTP server will change if any files within it are changed. I do think it would be useful if when copying from an FTP server that the date/time of the directory on your RISC OS filing system was stamped as on the FTP server.
The more information the merrier:-)

The trouble is when the directory is created and is datestamped when files are put into it the server changes the date stamp. Adding a file will change the stamp of all directories in the path.

David.

I think DDEUtils is just getting between the problem in FTPc and OS_GSTrans. The error is at add_prefix6 in the ddeutils file and is probably just trying to add a prefix to the same NULL pointer that OS_GSTrans is having problems with. Without ddeutils the problem in FTPc is more directly connected to OS_GSTrans.

OK I’ve fixed the NULL dereference and have put FTPc 1.50 on the FTPc website.

On a different subject I had to download the latest PI rom to use zeropain and found I got a lot of missed mouse presses using it which I don’t get with my own rom which has my usb changes.

FTPc 1.50

Excellent, pain free.

download the latest PI rom to use zeropain and found I got a lot of missed mouse presses using it

That doesn’t sound very fair after all the good work fixing FTP. I thought your USB additions had been added to the sources, perhaps not so then. Recent Pi ROMs have been good here, no missed clicks or repeating key presses.

The trouble is when the directory is created and is datestamped when files are put into it the server changes the date stamp. Adding a file will change the stamp of all directories in the path.

I think I understand that. It is when copying FROM an FTP server to say an SDFS disc that I was thinking it would be nice to date stamp the RISC OS Directory. Sorry if I’m not explaining this well.

Will this update also appear via PackMan?

Don’t know, don’t use it.

Don’t know, don’t use it.

It’s available via PackMan, which implies someone is maintaining and hosting it.

I’ve uploaded it now, it should appear in PackMan tomorrow after the indices are rebuilt. I was waiting until the problem reported here had been sorted.

Chris.

Try FTPc 1.51. It will preserve the filestamps of downloaded directories if your server supports the MLST command.

FTPc 1.51 retains directory date/time stamps when downloading from Spellings or F2S FTP servers. Brilliant!

Downloaded directories from an Orpheus server are not retaining their date/time stamp.
Very strangely the FTP window does display the directories correct date/time stamp just not the directory once saved to the local ADFS drive.
I can’t think what could cause this strange behaviour.

What you are seeing in the window is the output from the LIST command (an arbitary plain text output) which may or may not be correct in your timezone or even available/displayed in a standard form. That it why it was never added in the first place the ftp protocol was never designed to preserve filestamps. The timestamping I’ve added in FTPc uses commands added later to ftp (some are still draft status) specifically to read/write this sort of information so you know they are correct but as you have found out these commands are not always supported.

There are commands now to get computer readable directory lists with accurate UTC timestamps and other metadata – it would be possible to store riscos’s load and exec metadata but such an ftp client probably wouldn’t work on many servers.

This is one of the reasons I was reluctant to add timestamping for you in the first place. I knew it wouldn’t always work and I’m not happy that it sometimes does things and sometimes doesn’t
