| Series | swuforward: drop support for V1 Website | expand |
I just noticed this, sorry for being so late... Was this decision discussed at all? Could not find any discussion on this group. Assume a situation where a "module" is running SWUpdate in V1 mode, intended to be updated by the "master" device via the swuforward handler. The master in this scenario would be running the latest SWUpdate, no longer supporting V1, meaning the "module" is now unreachable for software upgrades. How would you solve the situation? Or are we forever stuck on SWUpdate release 2018.11?

Nobody complained - this patch is a follow up of this series: https://groups.google.com/forum/#!searchin/swupdate/swuforward$3A$20rework$20to$20use$20new$20Website%7Csort:date/swupdate/YIpxdN-G0cs/jwIG4i8lDQAJ This series (posted in June) has already dropped V1 support - the patch here just drop the check about the version, nothing more. It was already posted that the swuforwarder was broken with new libcurl releases: https://groups.google.com/forum/#!searchin/swupdate/swuforward%7Csort:date/swupdate/B6IvWMkQLnY/1CYJC7HLBAAJ > Could not find any discussion on > this group. See above - there was several threads about issues with swuforwarder in new releases. The legacy website itself was already dropped from the internal webserver (just "-V1" remained to let it compatible with swuforwarder) and the logical consequence was to rework the swuforwarder to be aligned with actual development. > > Assume a situation where a "module" is running SWUpdate in V1 mode, > intended to be updated by the "master" device via the swuforward > handler. The good question is why the master is singularly updated instead of running a system update on all modules, including the master. This guarantees that all modules will run the new SWUpdate (if successful) or the old one (if unsuccessful), but the system remains compatible. I agree that this a limitation, but because nobody complained, the limitation of dropping the single board update vs a system update was accepted. This is also how I arranged the change in my projects (just system update, no single update until target gets new SWUpdate). > The master in this scenario would be running the latest > SWUpdate, no longer supporting V1, meaning the "module" is now > unreachable for software upgrades.

This is possible and I could do if a customer asks it, but my customers have already upgraded and they are running newer SWUpdate. > Or are we forever stuck on SWUpdate > release 2018.11? This is quite dangerous - not only on SWUpdate, but you have to stick at least on older libcurl (< 7.6.1). Newer libcurl introduces an asynchronous mechanism that generates a race in the swuforwarder handler. The slaves modules receive a corrupted image and an update is not successful.

Hi Stefano, My bad for not finding the posts you mentioned. The issue with libcurl sure explains why V1 was dropped IMHO so quickly (not having swuforward supporting both V1 and V2 for a release or two). Thanks for explaining the situation with swuforward & V1.
