I've found that the fix is, in each script that use generators, change

gen = pagegenerators.PreloadingGenerator(gen)

with

gen = pagegenerators.PreloadingGenerator(gen, genFactory.step)

And that works for me.

That's because PreloadingGenerator has a step parameter that defaults to 50, and since none of the scripts specifies it, then it takes it as the current step value

I've actually written a patch which will return the pages in the requested order when using PreloadingGenerator: https://gerrit.wikimedia.org/r/#/c/199631/ You might give it a spin, though this bug here might still be relevant.

Hi @Ciencia_Al_Poder, it looks that -step parameter were deprecated (see: T109208). Also in PreloadingGenerator parameter was renamed fro step into groupsize (see: 1), which defaults to 50.

As I understand You problem was not particularly about step parameter, rather about correct order of returned pages, so I believe these should be resolved in independend change (see: 2).

Could You please check if Your problem occurs at current tip of master?

Yeah, order is now respected in -file generator. For me it's fine to close this task as declined/invalid
