It would have been useful to have these four things in four different patches, because that makes reviewing things a lot easier.

Altogether, the patch isn’t that large, but it is easier to spot any problems if changes are bundled into smaller logical sets.

Does anyone want to test this? I am just a little bit more concerned about breaking the package management system, because then we can’t fix things easily any more.

I understand, but I considered this (or at least the first two items) already as a single logical set. But you are right I could have split the patch in 4. Should I resubmit it as a v2 patchset of 4 ?

No, I don’t want to create any extra work for you now.

I just wanted to note this for future reference.

Hi Adolf

Thanks for testing.

Hi All,

I have run a test with this patch. I set up a CU 165 vm and ran pakfire with and without internet access to try and download 4 different addons. I then patched the pakfire functions.pl file and redid the test.

In both cases with internet access the four addons were successfully downloaded.

In both cases with no internet access I got the same error message that I needed Internet access to install addons.

From the point of view of a pakfire user there is no difference between with and without the patch.

The main pain points are when no meta-data could be downloaded (and is not already in cache) or when any of the lists is missing or could only be partly downloaded.

For my tests, I disabled internet by stopping unbound: [root@ipfire-test lists]# /etc/init.d/unbound stop Stopping Unbound DNS Proxy... [ OK ]

When unbound is started and internet is available, there is no difference to the user before or after the patch.

Not sure if any of the above errors messages would reach the user when pakfire wui is used, but at least there is less chance that meta-files or list.db's are getting corrupted or empty.

One thing I did notice with the current CU 165 is that after installing the selected addons the wui goes back to the original pakfire screen and does not show the addons having been installed in the right hand box. If I select the pakfire menu item again then the additional addons are shown. It looks like the wui page is not being updated after the addons have been installed. Should I raise this as a bug or is this an interim status as CU 165 is still a work in progress.

I see this behavior too in cu 165, both with original functions.pl and my patched version. So I don't think it is related with my changes.

Robin

Hi all

Today I received a patchwork notice that this patch was Superseded http://patchwork.ipfire.org/project/ipfire/patch/20220223202130.6104-2-robin...

So I was wondering which patch is superseding this one as I didn't supersede it myself, nor did I see a patch on the mailinglist tackling the same problem and it still looks valid against current next. I know there where improvements to pakfire.cgi, but this patch improves the errorhandling in the pakfire CLI command itself. So those pakfire.cgi patches should not be considered to supersede this one.

Is this possibly marked as superseded by accident?

Regards Robin

• Add true/false return codes to fetchfile, getmetafile and

getmirrors   indicating succes or failure.

• Check on those return codes and fail gracefully with clean

error message(s) when downloads fail.

• Replace duplicate meta-file fetching code in dbgetlist with

getmetafile function (fixing possibly missed cariage return   conversion in meta-files).

• Remove pointless 5 retries to download server-list.db in

selectmirror as fetchfile already retries 5 times.
