Reproducible Builds: Weekly report #149

Here’s what happened in the Reproducible Builds effort between Sunday February 25 and Saturday March 3 2018:

• ActiveState published an article called Reproducible builds: Introducing predictability into your pipeline.

• Will Thompson pointed out that Python dict order was defined in the language spec in December 2017.

• Helmut Grune filed Debian bug #891435, related to .buildinfo processing (“dpkg-genbuildinfo: Does not arch qualify Installed-Build-Depends”).

• There was a sprited discussion on the debian-devel mailing list regarding Debian’s reproducibility environment

• A Hamburg-based Mini-DebConf has been announced which is likely to bring together many people working on Reproducible Builds.

Version 91 was uploaded to unstable by Mattia Rizzolo. It included contributions already covered by posts of the previous weeks as well as new ones from:

• Chris Lamb:
  • Bug fixes:
    • Additionally dissect the classes.dex file from .apk files. (Closes: #890904)
    • Recursively reset the permissions of temporary directories prior to deletion. (Closes: #891363)
  • Reporting:
    • Print a nicer error message if you only specify one file by mistake.
    • Don’t show progress bar if we passed –debug; it just gets in the way.
  • Tidying:
    • Avoid necessary indentation around unconditional control flow.
    • Drop unused imports.
    • Ensure 4-line indentation.
    • Tidy an unnecessary assignment.
    • Add whitespace around operators.
    • Add a blank line before (and after) nested definition.
    • Don’t use ambiguous l variable names.
    • Drop a blank line.
    • Use more Pythonic old_level variable name (over oldLabel).
    • Add two spaces before inline comment.
    • Import LooseVersion as LooseVersion.
    • Move DOS/MBR check into the testsuite.
• Mattia Rizzolo:
  • Fix a UnicodeDecodeError with a non-UTF8 locale. and fix for Python less than 3.6.
  • Reset permissions only when we actually need to.
• Juliana Oliveira:
  • Replace .stderr_content with .stderr.
  • Replace/remove calls to .wait: (1) (2)
  • Replace subprocess.Popen() calls with subprocess.run().

In addition, Juliana — our Outreachy intern — continued her work on parallel processing; the above work is part of it.
