Originally there was no `path-info.*`, then there was `path-info.hh`,
then there was `path-info.cc`, but only for new things. Moving this
stuff over makes everything consistent.
Among all the characters that are allowed in a URL, both the percentage
sign "%" and the single quotation mark "'" needs escaping when written
as a environment variable in a systemd service file. While the single
quotation mark may be rare, the percentage sign is widely used to escape
characters in a URL. This is especially common in proxy setting, where
username and password may contain special characters that need
percentage escaping. This patch applies the following replacements:
% -> %%
' -> \'
Instead of needing to run `nix show-config --json | jq -r
'."warn-dirty".value'` to view the value of `warn-dirty`, you can now
run `nix show-config warn-dirty`.
If there was a prior nix installation that created this backup file and
then you tried to install it again, it would stop to tell you there is
this file. But if the file and its backup are identical in content,
there is no harm in continuing and in a later step overwriting the
existing backup file with the identical one. This is just a convenience
feature.
This should be a non-empty set, and so we don't want people doing this
by accident. We remove the zero-0 constructor with a little inheritance
trickery.
`DerivedPath::Built` and `DerivationGoal` were previously using a
regular set with the convention that the empty set means all outputs.
But it is easy to forget about this rule when processing those sets.
Using `OutputSpec` forces us to get it right.
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.
