[WIP] add assemble_subset #410
Conversation
- get_assemble_files() returns list of files needed for assembly - if buildpack.assemble_with_subset is set, only load assemble_files prior to running assembly scripts. Load the rest of the repo afterward conda opts in to this, but currently I think this works for everything *except* requirements.txt

R and Docker can't assemble from the subset because they can refer to local files. Julia can, though.
allows assemble_from_subset when requirements.txt doesn't contain any local references

Can a What do you think of a build pack being able to have assemble files that are run before copying over the repo and after? This way a build pack could support this but lets it opt out sometimes? Too complex/convoluted? |

Worth checking with #393 and the new way of specifying dependencies in Julia.

Good catch! I think it will affect Julia with the project stuff.
You can see an example of this in PythonBuildPack, where |

Closing in favor of #743 |
Marked WIP for discussion. I though I opened this ages ago, but apparently forgot.
This improves the use of build caching by separating 'assemble' into two steps:
This enables re-using the build cache from one build to the next, greatly expediting rebuilds in cases where the environment spec doesn't change.
Changes:
prior to running assembly scripts. Load the rest of the repo afterward
conda opts in to this, but currently I think this works for everything except requirements.txt. And requirements.txt could as well, as long as we peek in the contents to look for local
-e .references.
