It appears that on current macOS versions, our use of poll() to detect
client disconnects no longer works. As a workaround, poll() for
POLLRDNORM, since this *will* wake up when the client has
disconnected. The downside is that it also wakes up when input is
available. So just sleep for a bit in that case. This means that on
macOS, a client disconnect may take up to a second to be detected,
but that's better than not being detected at all.
Fixes#7584.
John has been part of every meeting since the beginning.
He took on a lot of work on behalf of the team, and provided useful suggestions in discussions, advocating for stability, reasonable design decisions, and maintainable code.
He was in general highly productive within the team process, and repeatedly helped us to keep focus on our stated goals.
Specifically, early on he suggested to gather more experience with the team reviews in order derive our values for the project encode a more structured approach to guiding contributions, which is slowly bearing fruit these days.
John is already the contributor with the most code changes to date (only topped by principal author Eelco), and is well-known to be highly knowledgeable about both high-level design and low-level internals of the code base.
He has continued to offer high quality work during the team's operation, which resulted in many pull requests getting merged that further the team's goals.
It is due time for John to be come an official team member and be granted merge access that he will surely exercise with the great care he is known for.
This way the links are clearly within the manual (ie not absolute paths),
while allowing snippets to reference the documentation root reliably,
regardless of at which base url they're included.
mdbook-linkcheck is not consistent about its warning setting.
It disables some warnings, but not the warnings about lack of
fragment checking support; hence the extra filtering.
Prior to this change, we had a bunch of ad-hoc string manipulation code
scattered around. This made it hard to figure out what data model for
string contexts is.
Now, we still store string contexts most of the time as encoded strings
--- I was wary of the performance implications of changing that --- but
whenever we parse them we do so only through the
`NixStringContextElem::parse` method, which handles all cases. This
creates a data type that is very similar to `DerivedPath` but:
- Represents the funky `=<drvpath>` case as properly distinct from the
others.
- Only encodes a single output, no wildcards and no set, for the
"built" case.
(I would like to deprecate `=<path>`, after which we are in spitting
distance of `DerivedPath` and could maybe get away with fewer types, but
that is another topic for another day.)
this form is much easier to maintain (also with minimal diffs), and
allows for more details on each operator.
this change a purely mechanical transformation, without changing any contents.
macOS doesn't have user namespacing, so the gid of the builder needs
to be nixbld. The logic got "has sandboxing enabled" confused with
"has user namespaces".
Fixes#7529.
This basically reverts 6e5165b773.
It fixes errors like
sandbox-exec: <internal init prelude>:292:47: unable to open sandbox-minimal.sb: not found
when trying to run a development Nix installed in a user's home
directory.
Also, we're trying to minimize the number of installed files
to make it possible to deploy Nix as a single statically-linked
binary.
The `fish_add_path` function is only available for fish 3.2.0 or newer,
and not on older versions.
This commit adds an alternative way to update the PATH when
`fish_add_path` does not exist.
