Hi Guix!
In https://issues.guix.gnu.org/46214, I proposed
a draft patch for adding a ‘hook’ mechanism to
guix publish. Now I would like to write some tests.
However, it seems the following construct is duplicated
for many tests:
(call-with-new-thread
(lambda ()
(guix-publish "--port=PORT" et cetera)))
This patch series introduces some abstraction.
Currently, there is only one patch yet, but more
will follow.
"make check TESTS=tests/publish.scm" still succeeds.
(Guix version: 23a5dcce1d893b8f5c5301ae3c1af863776ed3cf
with some not-yet-upstreamed changes).
Maxime

Subject: [PATCH] tests: publish: lessen code duplication.
* tests/publish.scm (spawn-guix-publish): introduce
procedure, and adjust tests to use it instead of
using an inline definition.

This is the third patch in the series. Description
from patch:
This way, there's no risk of accidentally reusing a
port number used by another test. This changes the
workings of the "/*.narinfo for a compressed file" test
a little, by not reusing the port from the test
"/*.narinfo with compression".
* tests/publish.scm
(*latest-port*, call-with-guix-publish, with-guix-publish):
automatically assign port numbers, and change tests to
use the new calling rules.

This is the fourth patch in the series.
It removes any explicit port numbers in the test.
This may be useful for preventing some potential
future problems with parallel "make check".

Subject: [PATCH 4/4] tests: publish: don't bind the test server to a port.
This way, multiple instances of 'make check TESTS=tests/publish.scm'
can be run in parallel. Also, there's no risk of the ports used
in this test conflicting with ports assigned to system services
anymore. This also prevents any potential future conflicts
with ports used by other tests that would lead to nondeterministic
test failures when parallel tests are enabled.
* guix/scripts/publish.scm
(when-bound): new parameter for communicating with
tests/publish.scm.
(guix-publish): inform tests/publish.scm about the port
the server socket was bound to via 'when-bound'. Also
correctly log to which port the server was bound.
* tests/publish.scm
(spawn-guix-publish): remove 'port' argument, ask "guix publish"
not to explicitely bind the server socket to a port and add the
port it was implicitely bound to, to the return values.
(call-with-guix-publish): adjust call to 'spawn-guix-publish'.
Also adjust the code to spawn the first server and 'publish-uri'
to the new semantics of 'spawn-guix-publish'.
