In Guix, there are two flags for controlling parallelism:
Note: When I say "derivation," think "package"
--cores=n
- controls the number of CPU cores to build each derivation. This is
the value passed to `make`'s `--jobs=` flag.
- defaults to 0: as many cores as is available
--max-jobs=n
- controls how many derivations can be built in parallel
- defaults to 1
Therefore, if set --max-jobs=$MAX_JOBS and don't set --cores, Guix could
theoretically spin up $MAX_JOBS * $(nproc) number of threads, and that's
no good.
So we could either default to --cores=1, --max-jobs=$MAX_JOBS
- Pro: --cores=1 means that `make` will be invoked with `-j1`,
avoiding problems with package whose build systems and test
suites break when running multi-threaded.
- Con: There will be times when only 1 or 2 derivations can be built
at a time, because the rest of the dependency graph all depend
on those 1 or 2 derivations. During these times, the machine
will be severely under-utilized.
or --cores=$MAX_JOBS, --max-jobs=1
- Pro: We don't encounter prolonged periods of
severe under-utilization mentioned above.
- Con: Many packages' build systems and test suites break when running
multi-threaded.
or --cores=1, --max-jobs=1 and let the user override with
$ADDITIONAL_GUIX_COMMON_FLAGS

c33b199456e57d83c21eacd36d3c56d0a123b0d0 guix: Bump glibc and linux-headers (Carl Dong)
65363a1bd8b886f5aef5fbc97ca88c9c9b243b21 guix: Rebase on 95aca2991b (1.2.0-12.dffc918) (Carl Dong)
Pull request description:
On bumping the time-machine:
```
A few changes which are useful for us:
1. 'gnu: cross-gcc-arguments: Enable 128 bit long double for POWER9.' is
now merged into master.
2. gnutls is bumped to 3.6.15 and the temporal test failure in
status-request-revoked is fixed. Note that this does not fix the case
where one has installed Guix v1.2.0 and is running a substitute-less
bootstrap build, since the `guix time-machine` command itself has a
dependency on gnutls v3.6.12 (the one with the broken test) and will
thus try to build it before attempting to jump forwards in time. This
does however, mean that those who build a version of Guix that also
contains this fix will not go backwards in time to build the broken
gnutls v3.6.12.
```
On bumping the rest:
```
Bump glibc and linux-headers to match those of our Gitian counterparts.
We also require a glibc >= 2.28 for the test-symbol-check scripts to
work properly.
The default BASE-GCC-FOR-LIBC also has to be bumped since glibc 2.31
requires a gcc >= 6.2
```
This is a prerequisite for #20980

ACK c33b199456e57d83c21eacd36d3c56d0a123b0d0 - I think going ahead with this now and to sycn back up to gitian is fine. It will also unblock #20980. Potential code signing related issues can be sorted out in #21239 and later PRs.

a6a1b106dcc4350e420c461171c47e4934087175 guix: only download sources for hosts being built (fanquake)
Pull request description:
For example, if a user is only interested in building for Linux, this saves downloading the macOS compiler and additional dependencies, which is meaningful on a slow/poor connection. This will result in a few additional `make` invocations, for the Linux hosts, however this is low overhead, and time-wise irrelevant in terms of the overall build.

The new time-machine commit contains a few small changes that make the
powerpc cross-toolchain work.
|
|
The new time-machine commit is Guix v1.2.0 with a yet-unupstreamed patch
for NSIS.
A few important changes:
1. Guix switched back from using CPATH to C{,PLUS}_INCLUDE_PATH as the
way to indicate #include search paths.
2. GCC's library is now split into a separate output, whereas before it
was included in the default output. This means that our gcc toolchain
packages need to propagate that output.
3. A few package versions were bumped
|
|
|
|
This allows depends-built packages to be cached.

When using worktrees or submodules, you'll see a `.git' plain text file
at the root of your working tree instead of the usual `.git' directory.
This plain text file will point to the real GIT_DIR, under the
GIT_COMMON_DIR. From experimentation, the full GIT_COMMON_DIR is
required to exist for operations such as git-archive(1), so we expose it
as readonly inside the container.

Most of the mingw-w64 toolchain changes have now been upstreamed, we can
point to a commit that exists upstream.
NOTE: I'm not changing the URL yet until we see that Guix upstream will
accept all my patches for macOS.
-----
The Guix tree that's referred to by this commit contains the following
changes relevant to our mingw-w64 build:
b066c25026
Adds a PACKAGES-WITH-*PATCHES procedure which we can use in the future
to apply patches to packages if those patches are not considered
appropriate to upstream Guix
4719b71572
Adds mingw-w64 (the libc itself) reproducibility patches, taken from
debian.
79825bee07 + 401d28e433 + c1c50cb5b0
Add mingw-w64 specific binutils patches, taken from debian.
Specifically, the "Make DLL import libraries reproducible" patch made
libbitcoinconsensus.dll.a build reproducibly. The followup commits
were hotfixes for my mistakes.
0f864175dc
Bumps mingw-w64 to v7.0.0. This is the first release that enables
secure APIs by default (which we need), and gains _FORTIFY_SOURCE
support. This will also be what Ubuntu Focal 20.04 LTS releases with.
cdf00cf75d
Bumps NSIS to v3.05. This is the first release that includes a fix for
a reproducibility bug found by some of the electrum developers. See
details here: https://sourceforge.net/p/nsis/bugs/1230/
|
|
|
|
|
|
This bump will includes a couple of commits which improve the
reproducibility of the mingw-w64 toolchain. Most of which came from
debian. They will be upstreamed as upstream Guix release timeline
allows.

- Clearer and more accurate prose
- Pin `guix pull' to commit rather than branch
- Just use `use-module' instead of `define-module'
- Use `bash-minimal' instead of `bash'
- Remove unneeded `tcsh' from manifest
- Explicitly use `python-3.7'
- Add comments about how {native,cross}-toolchains are produced and
why
