chrome: a default favicon, optional listing columns, and a table partial
Three services asked for a favicon field and bench argued against one: it
ships no icon deliberately, and its layout says why — a <link rel="icon">
pointing at an asset the binary does not have is a 404 on every page load, for
a file nobody asked for. A default that is a path hands that to every service
without a logo, so the default carries its own bytes instead: the brand's ring
as a data: URI, which cannot 404 and costs no request. It is a template.URL
because html/template rewrites any href whose scheme is not http, https or
mailto to "#ZgotmplZ" — the type is how a caller says it meant a data: URI.
Updated and Meta are optional for the reason the four listing services could
not agree: bench and spec have a modification time, dolt's schema has no
timestamp at all, and cover's index is a table of sparklines no shared partial
will render. A required column would have pushed dolt back onto a local copy.
Updated is a time.Time so the partial renders "3 hours ago" with the exact
stamp in the title once, rather than five services spelling it five ways.
srht-repo-table is a second partial over the same dot rather than a variadic
first one: growing columns on the cards would have made them worse cards for
the services that wanted cards.
Attach now installs Funcs itself, because the partials call reltime and
abstime and an unknown function is a parse error — a caller who had not merged
Funcs would have got a startup panic naming a template it never wrote. pages
consequently attaches before layering the service's own map on top, which is
what keeps a deliberate shadow working.
middleware: report panics through slog
The two log.Printf lines were the last stdlib log in ecore, and they printed
a formatted sentence where every service on the instance now emits structured
records — a panic report that cannot be filtered by path or grouped by route
is the one log line an operator most wants to query.
Through slog's default logger rather than one handed to RecoverPanics: a
library has no business choosing a handler. The service installs scribe's at
startup with SetDefault, and these land in the same stream, with the same
masking, as its own lines.
