PR Summary
Fix some warnings (see commit message for details) and some unreproducible parts. For doc CI, it sets
SOURCE_DATE_EPOCH
to the date of the latest tag, in order to reduce any possible timestamp changes.If you build docs with
SOURCE_DATE_EPOCH
set twice in a row, the only differences are now the example runtimes inserted by sphinx-gallery and one plot in the constrained layout tutorial (which warns that it may be unreproducible.)PR Checklist
