3s is too small a margin for a loaded slow system to start a bloated
program.
This leads to problems when tests are written on decent dev hardware
but later run on build farms of potentially slower hardware,
particularly in the case of non x86.
The chance of needing the timeout is actually very small, so those
rare 57s are a reasonable price to pay for fewer timeouts on build
farms, each of which should be investigated and usually fixed by
increasing the timeout.
This confused the hell out of me, as I didn't spot the
> The following flags are disabled by default ...
when reading about `pie`, because that sentence was hidden in the
previous hardening flag's section.
Also explain that `pie` hardening is on by default on musl.
pkgs.steam-run-native is defined as exactly the expression that
these instructions tell you to write, so the instruction is no
longer necessary since we can just tell you to use that.
The current example in the manual no longer builds, mainly because
`useDune2 = true` is required, but also because the inputs have changed.
The new examples are copied verbatim from nixpkgs.
With removeUnknownConfigureFlags, it's impossible to express a package
that needs --enable-static, but will not accept --disable-shared,
without overriding the result of removeUnknownConfigureFlags _again_
in pkgs/top-level/static.nix.
It would be much better (and more in line with the rest of Nixpkgs) if
we encoded changes needed for static builds in package definitions
themselves, rather than in an ever-expanding list in static.nix. This
is especially true when doing it in static.nix is going to require
multiple overrides to express what could be expressed with stdenv
options.
So as a step in that direction, and to fix the problem described
above, here I replace removeUnknownConfigureFlags with a new stdenv
option, dontAddStaticConfigureFlags. With this mechanism, a package
that needs one but not both of the flags just needs to set
dontAddStaticConfigureFlags and then set up configureFlags manually
based on stdenv.hostPlatform.isStatic.
The attributes got renamed in PR #126440 and in some places this caused
evaluation errors, e.g. the tarball job was saying (locally)
> attribute 'alsaUtils' missing, at /build/source/nixos/modules/services/audio/alsa.nix:6:4
and I suspect that trunk-combined jobset's failure to evaluate was also caused.
We were using Pandoc’s Markdown parser. This is non-standard and might cause issues when we finally switch to some other tool.
Since RFC 0072 agreed on CommonMark, let’s switch to that.
We will use some extensions to make the limited syntax bearable but these are official so they should be more portable.
We are still using Pandoc’s Markdown parser, which differs from CommonMark spec slightly.
Notably:
- Line breaks in lists behave differently.
- Admonitions do not support the simpler syntax https://github.com/jgm/commonmark-hs/issues/75
- The auto_identifiers uses a different algorithm – I made the previous ones explicit.
- Languages (classes) of code blocks cannot contain whitespace so we have to use “pycon” alias instead of Python “console” as GitHub’s linguist
While at it, I also fixed the following issues:
- ShellSesssion was used
- Removed some pointless docbook tags.
