Cheers, 1. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=901256 -------- Forwarded Message -------- Subject: dak: dakweb: allow for looking up files by sha256sum Date: Sun, 10 Jun 2018 12:59:01 -0400 From: Alexandre Viau <aviau@debian.org> To: submit@bugs.debian.org Package: ftp.debian.org Severity: wishlist Tags: patch I am currently building a tool that uses dakweb to look for files in the archive. While file_in_archive is useful, I already have the sha256sum of the file I am looking for so I would like to perform more exact queries. Please consider applying the attached patch which also fixes an error in the docstring of file_in_archive. Cheers, -- Alexandre Viau aviau@debian.org

Subject: [PATCH] dakweb: /sha256sum_in_archive/<sha256sum> endpoint
This patch creates a new /sha256sum_in_archive/<sha256sum>
endpoint in dakweb. The endpoint allows for searching for
files with a marching sha256sum in the archive.
I have also taken the time to fix docstrings of file_in_archive
which wrongly indicated that the return type was a dictionary.
