It all works fine now, thanks Martin.

Topic: General / Numbered Mode RPC

Is there an example of a extra numbered Mode – that works with the RPC onwards?

ie one that responds to Service_ModeExtension &50
Is there any upto date info on that Service?

Topic: Bugs / LanManFS losing directory contents after a while

It might be worth performing a *Cat command on the corresponding folders and compare the results of the same command when the problem is not present. It may be that the list provided is just truncated (or skipping the first entries due to an index initialisation issue) but *Cat provides an unsorted view of the folder’s content while the Filer sort’s the folder’s content and may hide the issue.

Topic: Bugs / LanManFS losing directory contents after a while

I wonder if simpler displays using commands like *Cat and *Ex also show the same problem as the Filer?

And at an even lower level, what about SYS OS_GBPB 9-12 ?

Topic: Bugs / LanManFS losing directory contents after a while

Refresh does not change anything or does how the display is sorted and the missing files don’t seem to be after folders.

Topic: Community Support / Cannot boot 5.24 on RPi 3B+

My Iyonix has not, neither has my HDMIPi.

They will be there somewhere – you have just not found them yet! The Iyonix could have been generated by the ‘Save choices’ option on the ShareFS memu … but I cannot see what it saves and where! On the Pis that option is faded (because the SDFS discs are deemed ‘removable’), so it has to be done manually.

Note you can use the same Obey file on several machines, if you use something like:

If "<Inet$HostName>" = "RasPi"  then *Share SDFS::RISCOSpi  PiSD
If "<Inet$HostName>" = "Beagle" then *Share SDFS::RISCOSpi  BeagleSD

Topic: Bugs / LanManFS losing directory contents after a while

Has anyone reproduced this when connected to a windows machine?

My first attempt to reproduce the problem by connecting to a windows laptop and leaving it for an hour didn’t reproduce any problems.

Does selecting refresh for the folder do anything?

Are the missing files immediately after folders?

Does how the display is sorted or whether you are using large icons, detail etc. make any difference?

Topic: Community Support / Cannot boot 5.24 on RPi 3B+

Presumably your other machines already have something similar somewhere.

My Iyonix has not, neither has my HDMIPi. But certainly they have something (invisible) that my PiTop2 has not. Anyway, I put an Obey file in the Boot and it works.

Thank you very much, Martin, for both your patience and your help!

Topic: Bugs / LanManFS losing directory contents after a while

Yesterday (saturday, midday ish) I downloaded os 5.25 (july 20) to see if there had been any changes to this problem.
All I done was to examine folders stored on my Nas and open up a few pipedream files and text files.
Every thing seemed ok until about an hour ago when a lot of files are not shown, and the system was idle between it being ok at 9am this morning to 11am(ish) when it was not ok, which seems to indicate some sort of time related problem (as it seemed to me when I tried it on os 5.24 a few months ago)

If I look in directories that are shown, some of the files and folders in there are missing (but not always!). But it is consistent ie its the same files/folders are always shown as missing if you open/close/open folders. With the missing files/folders I can’t see pattern (file name wise), and as suggested by Colin when I do a file count, it is incorrect in the folders that when opened don’t show all the files/folders.

Great. That explains the mystery of the missing shares.
Shares are not permanent … but they can easily be set up at boot time by creating an Obey file, which can be in !Boot.Choices.Boot.Tasks and often called Shares. This Obey file should contain the required Share commands.

Presumably your other machines already have something similar somewhere.

Topic: Bugs / LanManFS losing directory contents after a while

Are the same files going missing or does it look like the missing files are just random? Does counting a folder count the correct number?

Topic: Community Support / Cannot boot 5.24 on RPi 3B+

I am now assuming that the first FWshow was from PiTop2 before the Iyonix was started. Then you started the Iyonix and did the second FWshow on that. Then you did the third FWshow on the PiTop2, which showed that the Iyonix has connected ok.

That’s right. (oh, communicating via text is pretty difficult, thanks for your patience)

I did the share and it worked. When I reset PiTop2, Pi2HD is not visible anymore. So, Martin, it might be my last question: how do I make it permanent?

Topic: Bugs / LanManFS losing directory contents after a while

This is definitely different to the 2016 fixes, I’m afraid. The simple way to reproduce it is to leave LanManFS idle for approx 30 mins or so (go have dinner whilst still connected) then try opening some folders. You’ll almost certainly find that some files are missing. Whether this is specific to some NAS Samba implementations, I don’t know (as I say, I’ve had it reported on QNAP and Synology NAS devices with a variety of firmwares, but those tend to be the only LanMan servers we connect to).

If reproducing is a problem, I’ll check with Richard and John – between us we should have a loner NAS that we can provide, if there’s dev time available.

I think there is some confusion because you are posting results saying ‘from xxx and yyy’ but they will be different! It may only be where asterisks appear, but they are significant.

I am now assuming that the first FWshow was from PiTop2 before the Iyonix was started. Then you started the Iyonix and did the second FWshow on that. Then you did the third FWshow on the PiTop2, which showed that the Iyonix has connected ok.

On the PiTop2, in a command window, enter
*Share SDFS::RISCOS Pi2HD
where SDFS::RISCOS is the filing system and disc name displayed in the title of Filer window when you click Select on your SD card icon.

Then look in the Discs window. Pi2HD should appear … on all connected machines after a moment or two.

ps – perhaps you could replace some of your last duplicate posts with <deleted> please?

I assume this is on your Iyonix?
bq. I assume this is on your PiTop2?
Both assumptions are right.

I have three machines:
Machine – Hostname – IP adress
Iyonix – Iyonix – 192.168.178.25
HDMIPi – HDMIPi – 192.168.178.20
Pi – PiTop2 – 192.168.178.24

The test results are from the Iyonix and PiTop2
The Iyonix and the HDMIPi show their icon in Discs, PiTop2 doesn’t.

Peter: have you got three machines on your network?
Are you sure they have different host names and IP addresses?

On my Iyonix and the Pi:

I assume this is on your Iyonix?

On the Pi and the Iyonix:

I assume this is on your PiTop2?

On my Pi:

but this seems to have the same name and IP address as ‘On the Pi and the Iyonix’, which will not work.

Topic: Community Support / Cannot boot 5.24 on RPi 3B+

Exactly what commands are being issued to *Share the discs on PiTop2?

None. I just changed the name by clicking Boot:Configuration:Network:Internet:Host names:Host name into PiTop2. But before I did, just after installing a fresh image, Discs didn’t show the disc.

I compared the settings with my other machines, they are the same.

Topic: Announcements / RiscLua 7

I’ve taken what I’ve got so far and put it on my website

Many thanks. I have been trying it with RiscLua 7. Perhaps I should apologize for its most recent innovation, declaration of globals.

foo = bar

global.foo = bar

for the first use of foo. So I am still in the process of doubleclicking !AppLua, looking at the error message and inserting the indicated global. prefix. Though tedious it is quite instructive; in fact it convinces me that it is an essential innovation, because it is a useful debugging tool. For example it is showing me that at line 241 of !AppLua.LuaTbox.AppLua the argument DealWith_PreInit to pcall has not yet been encountered.

I feel a bit guilty about making RiscLua a moving target, but in this case less so. RiscLua 6 used dynamic linking for C libraries, but since then GCC has moved to a newer version and I cannot get dynamic linking to work. I suspect it has something to do with the translation between Unix and RISC OS filenames. Anyway, I have reverted for the time being to static compilation for RiscLua 7. The actual code for the riscos library has not changed for decades, so I would be surprised if the handling of SWI errors is different. Can you send me relevant bits of code to test?

I much admire the work you have put in to AppLua. Following Joe’s lead with AppBasic is an interesting exercise. But, as I may have already expressed, making a translation (calque?) from BASIC to Lua makes one aware of the differences, particularly when it comes to scoping of variables. In BASIC global variables are the norm, in Lua local variables are the norm. Still, there is much to be said for getting things to work first, and then tackling changes of style later in a controlled way.

I’m very sorry, Martin, I made a mistake (I shouldn’t have done that on such a late hour):

Only my Pi:
Type 5: (Hosts)
*Name=PiTop2 Holder=192.168.178.24
Type 1: (Discs)

On my Iyonix and the Pi:
No remote nets
Type 2: (printers)
Type 5: (Host)
*Name=Iyonix Holder=192.168.178.25
Name=PiTop2 Holder=192.168.178.24
Type 1: (Discs)
*Name=Backup Holder=192.168.178.25 (Not 192.168.172.25)
*Name=Iyonix Holder=192.168.178.25

On the Pi and the Iyonix:
No remote nets
Type 5: (Host)
*Name=PiTop2 Holder=192.168.178.24
Name=Iyonix Holder=192.168.178.25
Type 1: (Discs)
*Name=Backup Holder=192.168.178.25 (Not 192.168.172.25)
*Name=Iyonix Holder=192.168.178.25

All the IP adresses are the same, except the last part. Sorry.

Topic: Community Support / Scanning over a Network (Cannon Pixma MP499)

nobody seems to mention anything to do with using cups-lpd on Debian so I’m a bit stuffed as to what to do next

On my raspian jessie Pi3 the miniserver is in /usr/lib/cups/daemon/cups-lpd

I haven’t messed with systemd services myself. Check the ubuntu forums and also this guy seems useful brain4free

Though you’ll want to use the actual server, not a shell script to capture the output…

Before you get too excited about using a Pi as a print server, make sure that any needed printer drivers are available as ARM binaries, some are x86 only. :-(

Topic: Community Support / Cannot boot 5.24 on RPi 3B+

If I am to create one myself, I would need: 1) a second SD card, 2) a USB to SD adapter and 3) SystemDisc?

Yep

Topic: Community Support / Cannot boot 5.24 on RPi 3B+

If you are serious out using your Pi3 then i would recommend that you get a copy of SystemDisc, you are also not limited to booting from SDcard you can boot from any USB device.
some examples https://riscosbits.co.uk/pissdup.htm or http://au.element14.com/element14/pi-desktop/element-14-pi-desktop-hatencl/dp/2687142 go to the UK site if in UK, this is what I use, you can get MSata Drives Cheap and they don’t have the problem the SD card Suffer from.
The good thing about Systemdisc is it allows you to just format the drive then just add the right boot folder needed ready to add the firmware and boot files , not limiting yourself to using other systems to write image files to SDCards.

Topic: Announcements / LuaTahi

p.s.: This one comes with its own embedded rlua5 binary & libs, because rlua6 breaks it, and rlua7 breaks it even more. Oh well ;)

Which version of RISC OS are you using? More specifically, which version of WindowManager?

Both rlua6 and rlua7 use VFP and require at least WindowManager 5.60 (17-02-2018) which has a bug fixed relating to switching VFP contexts.

Topic: Announcements / RiscLua 7

There does seem to be some difference though as AppLua works fine on RiscLua 5 and 6 but it fails on version 7 (segmentation fault; stack frame out of bounds). I’ll do some more digging later on.

Anyway, good luck with the digging.

The cause of the error was in AppLua (using MessageTrans before file descriptor was set up). However the same code doesn’t crash on RiscLua 6, the call to MessageTrans returns an error. This suggests that RiscLua 7 doesn’t handle errors returned by SWIs correctly.

I am curious to know how Applua is progressing :).

It’s coming along albeit in bits and pieces, and there’s still a long way to go. Anyway, I’ve taken what I’ve got so far and put it on my website (I’ll do a proper announcement later on).

Topic: Community Support / Cannot boot 5.24 on RPi 3B+

I am interested in a 32GB image, would it be possible to have such available? A 16GB might also do, I consider getting one such card also for it, though given the previous experience, I have some fear about whether it will work.

If I am to create one myself, I would need: 1) a second SD card, 2) a USB to SD adapter and 3) SystemDisc?
