Package: python-pyswarms-doc Severity: wishlist Tags: patch upstream User: reproducible-bui...@lists.alioth.debian.org Usertags: randomness
Dear Maintainer, I'm an occasional volunteer contributor to the Reproducible Builds[1] project, and recently noticed that your package failed an automated test for Debian build reproducibility[2] that also appeared in the results of Debian's Salsa-CI reprotest[3]. The cause of the problem relates to two images named ani.gif and ani_h.gif respectively in the options_handler.ipynb documentation tutorial file. In particular, there is an IPython notebook cell[4] declared as type Markdown that presents the images, and notably does _not_ include an explicit HTML 'alt' attribute[5] describing the contents of each image. Part of the documentation rendering process - I have not determined exactly what yet - adds an 'alt' attribute when it does not exist, and generates a randomized hex string to use as the value of the attribute. This causes the resulting python-pyswarms-doc package to vary on each build. Providing a static value for the alt attribute on these two image tags allows the python-pyswarms-doc package to build reproducibly (bit-for-bit identical). I've created a branch on Salsa with a proposed change, and will open that as a merge request against pyswarms.git for your review.
