Daily recipe: Automatic build fails if the very previous build was manual

[Boris Dušek]

Hello,

I am using the great daily recipe build feature of Launchpad.

When I trigger a manual build, and then change to automatic daily build, and the upstream and packaging source code does not change between the manual and automatic build, then the first automatic build fails (or more precisely, what fails is the source package upload of the first source package automated build), claiming that the source tarball with this name but different contents has been already uploaded (the different contents being probably result of some gzip timestamp being different or other things).

Example log:
https://code.launchpad.net/~dusek/+archive/spd-daily/+buildjob/2427191

Note that there are 2 typical scenarios:

1. I setup a new packaging recipe on Launchpad, setup for manual builds first. I trigger a manual build to test that it builds fine. After debugging the recipe using subsequent manual builds, i.e. after it builds fine, I turn on the automatic daily build for the recipe. Within 24 hours, an automatic build is triggered and it fails (in both cases this has happened, the source code in lp branches referenced from the recipe has not changed between the last manual and first automatic build)

2. I have automatic build setup and working successfully, it has already successfully built a few new versions of the package in the automatic daily regime. Then an important fix comes out upstream that I want to test immediately, so I trigger the manual build (leaving the automatic build option turned on). The manual build finishes fine, but the next automatic build (triggered within 24 hours) fails.

Just clarifying that in the linked example log, the error is in the "uploadlog", not the "buildlog", and that the log error contains this error message:

...
