+read-at-tako was checking for the zero tako, but had the conditional
inverted. Here, we correct the conditional, and fold the
+may-read check into the whole.
=case was added as an argument to read-s to support %cs subs
it was accidentally removed as an argument during a merge,
breaking %cs subs by causing it to always crash in a
comparison between case and [%da now], because case resolved
to the mold rather than a value. this commit restores
intended functionality.
The refactor from aeon to tako is from May 2022, but unmerged until
March 2023. In the meantime, I added another usage of aeon-flow in July
2022, which was converted to aeon-flow in March 2023, but the argument
itself was unchanged. This meant we didn't save the cache after +goad.
if all=& in |yawn, it will delete all listeners ducts,
without notifying them about it, which seems bad,
so we migh adress that separatedly.
Also, it might be cleaner to have a separate task instead of
a flag, to have two paths for "remove me" and "remove all",
this way there won't be an option for a listener to remove all
others, and that will have to be handled explicitly.
We were retrying failed kelvin upgrades as many times as we had apps
that needed to be suspended, because suspending an app triggers an
attempt to run the next kelvin upgrade. This suspends all those apps in
one batch move, and then tries the next kelvin upgrade only once at the
end.
Fixes#6407
Partially addresses #6285
Previously, if the pointer for a syntax error pointed to the end of the file
(and the file ended in a newline) the code snippet rendering would try to
display a line _beyond_ the end of the file, causing a crash.
Here, we detect that case, and display `<<end of file>>` instead.
(Originally merged through #5812, but got lost somewhere along the way.)
Fixes#6287.
