PackMan

I just got a Segmentation Fault from PackMan 0.9.5 Beta (13 Apr 2020). To make it happen, click on the iconbar to open the main window, click on the search icon on the toolbar to open the search dialogue (focus should now be in the writable icon), and the press Ctrl+K.

I think this is probably a bug with the new clipboard handling as PackMan doesn’t do anything with that key combination. The crash also doesn’t appear on RISC OS 5.24 running on RPCEmu.

Ok I’ll try again after the OS release.

I have downloaded a fresh RC16 image, put a rom suitable for the Pi 4 which supports EtherGENET into it and run it on a Pi 4. If I run Packman and respond to its message: ‘The list of packages has not been updated for 142 days. Would you like to update the list from the Internet now?’ it updates its !Packages in Resources. So far all appears well.

If you then upgrade the SharedUnixLibrary from 0.14-1 to 0.16-1 it appears to work but leaves a blank line after the DPlgScan entry and the stratagus entry. The !Packages file is now corrupt and interesting things start to happen.

If instead you try to upgrade HForm it will ask to remove PDF 3.02.1.24.1-3 and upgrade SharedUnixLibrary 1.14-1 to 1.16-1 (despite HForm having no dependencies) leading to a segmentation fault. If you ‘withdraw’ one of these unwanted items, you get ‘An unexpected error has occurred .. the error was Invalid component ID (0×1004).. Please report it to the Packman author.’ One of the entries in the packages list is blank suggesting corrupt pointers again.

If you remove PDF and SharedUnixLibrary from the list of packages it thinks it is maintaining the problem disappears (so this offers a temporary and expedient fix).

This suggests either that one of the external resources is broken or the !Packages as of last week is broken. Another error that might occur is ‘<url> malformed’.

Hope this is helpful. PM sent.

Better place…
