| Firstly, I apologize if this was discussed already. I tried searching
| the mailing list archive and open PRs, but didn't see anything about
| this topic.
Maybe a PR should be opened on the subject then :-)
| The problem is apparently with 'do-fetch' in bsd.port.mk: the condition
| for fetch complete is the existence of an appropriate filename in
| distfiles, based on the (invalid) assumption that the file will only be
| there if completely fetched.
Maybe I am completely missing something, but how would we be able to
tell if a distfile is truncated, or if there actually *is* a checksum
mismatch (and the file was completely downloaded)?
If we can figure out a way to tell if a distfile is truncated, then I
think this would be a great feature to have. Or maybe we introduce a
variable RESUME_DOWNLOAD to tell ports that it was a partial fetch. For
example, if I am on a dialup, I might need to ^C the fetch to use a
phone line, then I could make -DRESUME_DOWNLOAD. Or maybe we can do the
fetch to a temp directory (/usr/ports/distfiles/downloading/ or
something), and after fetch(1) completes move the distfile into the
appropriate ${DISTDIR}. That way we would be able to tell if fetch(1)
finished or the user interrupted it.
What do others think?
