+**Welcome to the September 2020 report from the [Reproducible Builds](https://reproducible-builds.org) project.** The motivation behind the Reproducible Builds effort is to ensure no flaws have been introduced from the original free software source code to the pre-compiled binaries we install on our systems. In our monthly reports, we attempt to summarise the things that we have been up to over the past month, but if you are interested in contributing to the project, [please visit our main website]({{ "/" | relative_url }}).

+## Events
+
+Sadly, due to the unprecedented events in 2020, there will be [no in-person Reproducible Builds event this year](https://lists.reproducible-builds.org/pipermail/rb-general/2020-September/002045.html). However, the Reproducible Builds project intends to resume meeting regularly on IRC, starting on **[Monday, October 12th at 18:00 UTC](https://time.is/compare/1800_12_Oct_2020_in_UTC)** ([full announcement](https://lists.reproducible-builds.org/pipermail/rb-general/2020-September/002049.html)). The cadence of these meetings will probably every two weeks, although this will be discussed and decided on at the first meeting. An [editable agenda is available](https://pad.sfconservancy.org/p/reproducible-builds-meeting-agenda).
+
+[![]({{ "/images/reports/2020-09/isdd2020.png#right" | relative_url }})](https://www.eco.de/events/internet-security-days-2020/isdd-2020-agenda/#best_practises__aus_erfahrungen_lernen)
+
+On 18th September, Bernhard M. Wiedemann gave a presentation in German titled [*Wie reproducible builds Software sicherer machen*](https://www.eco.de/events/internet-security-days-2020/isdd-2020-agenda/#best_practises__aus_erfahrungen_lernen) ("How reproducible builds make software more secure") at the [Internet Security Digital Days 2020](https://www.eco.de/events/internet-security-days-2020/) conference. ([View video](https://player.vimeo.com/video/451962745#t=429m24s).)
+
+On Saturday 10th October, Morten Linderud will give a talk at [Arch Conf Online 2020](https://conf.archlinux.org/) on [*The State of Reproducible Builds*](https://pretalx.com/arch-conf-online-2020/talk/39BGNS/) in the Arch Linux distribution:
+
+> The previous year has seen great progress in Arch Linux to get reproducible builds in the hands of the users and developers. In this talk we will explore the current tooling that allows users to reproduce packages, the rebuilder software that has been written to check packages and the current issues in this space.
+
+During the [Reproducible Builds summit in Marrakesh]({{ "/events/Marrakesh2019/" | relative_url }}), [GNU Guix](https://guix.gnu.org), [NixOS](https://nixos.org) and [Debian](https://debian.org) were able to produce a bit-for-bit identical binary when building [GNU Mes](https://www.gnu.org/software/mes/), despite using three different major versions of GCC. Since the summit, additional work resulted in a bit-for-bit identical Mes binary using `tcc` and this month, [a fuller update was posted]({{ "/news/2019/12/21/reproducible-bootstrap-of-mes-c-compiler/" | relative_url }}) by the individuals involved.

+## Development work
+
+#### [Debian](https://debian.org/)
+
+[![]({{ "/images/reports/2020-09/debian.png#right" | relative_url }})](https://debian.org/)
+
+Chris Lamb uploaded a number of Debian packages to address reproducibility issues that he had previously provided patches for, including [`cfingerd`](https://tracker.debian.org/pkg/cfingerd) ([#831021](https://bugs.debian.org/831021)), [`grap`](https://tracker.debian.org/pkg/grap) ([#870573](https://bugs.debian.org/870573)), [`splint`](https://tracker.debian.org/pkg/splint) ([#924003](https://bugs.debian.org/924003)) & [`schroot`](https://tracker.debian.org/pkg/schroot) ([#902804](https://bugs.debian.org/902804))
+
+Last month, an issue was identified where a large number of Debian `.buildinfo` build certificates had been 'tainted' on the official Debian build servers, as [these environments had files underneath the `/usr/local/sbin` directory](https://bugs.debian.org/969084) to prevent the execution of system services during package builds. However, this month, Aurelien Jarno and Wouter Verhelst fixed this issue in varying ways, resulting in a special `policy-rcd-declarative-deny-all` package.
+
+Building on Chris Lamb's [previous work on reproducible builds for Debian .ISO images](https://lists.reproducible-builds.org/pipermail/rb-general/2020-August/002018.html), Roland Clobus announced his work in progress on making the [Debian Live](https://wiki.debian.org/DebianLive/) images reproducible. [[...](https://lists.reproducible-builds.org/pipermail/rb-general/2020-September/002044.html)]
+
+79 reviews of Debian packages were added, 23 were updated and 17 were removed this month adding to [our knowledge about identified issues](https://tests.reproducible-builds.org/debian/index_issues.html). Chris Lamb added and categorised a number of new issue types, including packages that [captures their build path via `quicktest.h`](https://salsa.debian.org/reproducible-builds/reproducible-notes/commit/18a02c14) and [absolute build directories in documentation generated by Doxygen`](https://salsa.debian.org/reproducible-builds/reproducible-notes/commit/2354fa49), etc.
+
+[![]({{ "/images/reports/2020-09/intoto.png#right" | relative_url }})](https://in-toto.io/)
+
+Lastly, Lukas Puehringer's uploaded a new version of the [*in-toto*](https://in-toto.io/) to Debian which sponsored by Holger Levsen. [[...](https://tracker.debian.org/news/1173455/accepted-in-toto-050-1-source-into-unstable/)]
+
+### [diffoscope](https://diffoscope.org)
+
+[![]({{ "/images/reports/2020-09/diffoscope.svg#right" | relative_url }})](https://diffoscope.org)
+
+[*diffoscope*](https://diffoscope.org) is our in-depth and content-aware diff utility that can not only locate and diagnose reproducibility issues, it provides human-readable diffs of all kinds too.
+
+In September, Chris Lamb made the following changes to [diffoscope](https://diffoscope.org), including preparing and uploading versions `159` and `160` to Debian:
+
+* New features:
+
+    * Show "ordering differences" only in `strings(1)` output by applying the ordering check to all differences across the codebase. [[...](https://salsa.debian.org/reproducible-builds/diffoscope/issues/216)]
+
+* Bug fixes:
+
+    * Mark some PGP tests that they require `pgpdump`, and check that the associated binary is actually installed before attempting to run it. ([#969753](https://bugs.debian.org/969753))
+    * Don't raise exceptions when cleaning up after `guestfs` cleanup failure. [[...](https://salsa.debian.org/reproducible-builds/diffoscope/commit/aca4221)]
+    * Ensure we check `FALLBACK_FILE_EXTENSION_SUFFIX`, otherwise we run `pgpdump` against all files that are recognised by `file(1)` as `data`. [[...](https://salsa.debian.org/reproducible-builds/diffoscope/commit/bab3e0e)]
+
+* Codebase improvements:
+
+    * Add some documentation for the `EXTERNAL_TOOLS` dictionary. [[...](https://salsa.debian.org/reproducible-builds/diffoscope/commit/c6a438a)]
+    * Abstract out a variable we use a couple of times. [[...](https://salsa.debian.org/reproducible-builds/diffoscope/commit/6bb06d2)]
+
+* [diffoscope.org](https://diffoscope.org) website improvements:
+
+    * Make the (long) demonstration GIF less prominent on the page. [[...](https://salsa.debian.org/reproducible-builds/diffoscope-website/commit/aae926e)]
+
+In addition, Paul Spooren added support for automatically deploying Docker images. [[...](https://salsa.debian.org/reproducible-builds/diffoscope/commit/53d1aad)]
+
+### [Website / documentation](https://reproducible-builds.org/)
+
+[![]({{ "/images/reports/2020-09/website.png#right" | relative_url }})]({{ "/" | relative_url }})
+
+This month, Chris Lamb made a large number of updates to the [main Reproducible Builds website]({{ "/" | relative_url }}) and related documentation:
+
+* Update a few titles and the ordering of some top-level navigation elements. [[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/9423f45)]
+* Drafted, published and publicised [August's monthly report]({{ "/reports/2020-08/" | relative_url }}).
+* Improve the documentation on how to signup to [Salsa](https://salsa.debian.org/). [[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/b4da392)]
+* Add some more links to academic papers. [[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/1b60222)]
+* Also include the general news in our RSS feed [[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/62370fc)] and drop including weekly reports from the RSS feed (they are never shown now that we have over 10 items) [[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/18211d6)].
+* Update ordering and location of various news and links to tarballs, etc. [[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/131a83d)][[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/4aa0407)][[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/5998e6f)]
+* Kept [isdebianreproducibleyet.com](https://isdebianreproducibleyet.com) up to date. [[...](https://github.com/lamby/isdebianreproducibleyet.com/commits?author=lamby&since=2020-09-01T00:00:00Z&until=2020-10-01T00:00:00Z)]
+* Worked with [Amateur Radio Digital Communications](https://ampr.org/) in order to announce their [generous sponsorship of the Reproducible Builds project]({{ "/news/2020/09/25/ardc-sponsors-the-reproducible-builds-project/" | relative_url }}).
+
+In addition, Holger Levsen re-added the [documentation]({{ "/docs/" | relative_url }}) link to the top-level navigation [[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/83e2a60)] and documented that the `jekyll-polyglot` package is needed to build the site [[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/b8c3b09)]. Lastly, `diffoscope.org` and `reproducible-builds.org` were transferred to [Software Freedom Conservancy](https://sfconservancy.org/). Many thanks to Brett Smith from Conservancy and Jérémy Bobbio (*lunar*) for their help with transferring.
+
+#### Upstream patches
+
+The Reproducible Builds project detects, dissects and attempts to fix as many currently-unreproducible packages as possible. We endeavour to send all of our patches upstream where appropriate. This month, we wrote a large number of these patches, including:

+## Testing framework
+
+[![]({{ "/images/reports/2020-09/testframework.png#right" | relative_url }})](https://tests.reproducible-builds.org/)
+
+The Reproducible Builds project operates a [Jenkins](https://jenkins.io/)-based testing framework to power [`tests.reproducible-builds.org`](https://tests.reproducible-builds.org). This month, Holger Levsen made the following changes:
+
+* [Debian](https://debian.org/):
+
+    * Shorten the subject of "nodes have gone offline" notification emails. [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/2f6a1242)]
+    * Also track bugs that have been [usertagged](https://wiki.debian.org/bugs.debian.org/usertags) with `usrmerge`. [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/79ac64a9)]
+    * Drop abort-related codepaths as that functionality has been removed from [Jenkins](https://jenkins.io/). [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/f5c1d675)]
+    * Update the frequency we updatre base images and status pages. [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/cf2497e7)][[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/5461a909)][[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/9c21f055)][[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/6b2aca38)]
+
+* [Status summary view page](ttps://tests.reproducible-builds.org/trbo.status.html):
+
+    * Add support for monitoring `systemctl` status [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/6fb89cbc)] and the number of [diffoscope](https://diffoscope.org/) processes [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/a10c53c9)].
+    * Show the total number of nodes [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/06aefcc6)] and colourise critical disk space situations [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/07297a9a)].
+    * Improve the visuals with respect to vertical space. [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/4d7943c4)][[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/a1e43681)]
+
+* Debian rebuilder prototype:
+
+    * Resume building random packages again [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/e9a98ffa)] and update the frequency that packages are rebuilt. [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/02487ea2)][[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/84c959c3)]
+    * Use `--no-respect-build-path` parameter until `sbuild` 0.81 is available. [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/62e8b2ac)]
+    * Treat the inability to locate some packages as a `debrebuild` problem, and not as a issue with the rebuilder itself. [[...](https://salsa.debian.org/qa/jenkins.debian.net/commit/cb788349)]
