This changes when various libraries that provide contract
support to possible contracted bindings to declare when
those bindings are needed.
Probably, each static-contract combinator should manually
add to the list, instead of having one fixed static list,
but this is a start.
Saves about 10ms in startup for an empty TR module on my
laptop.
Thanks to Robby for the idea.
There seems to be a problem in kqueue() on Mac OS X for watching for
FIFO write availability, where adding a read event for the same FIFO
(at a different file descritor) can disable the write event.
Merge to v6.1.1
If a write to a non-blocking descriptor fails, then try again
with fewer bytes, since nothing in the spec write() seems to
promise writing partial amounts. In particular, writing to
a FIFO no Mac OS X might fail even if there are a few bytes of
space; as it happens, the select() function seems to compensate
and claim that such a FIFO is full, but kqeueue() doesn't.
This implementation runs about 10% faster than the old when searching
for "λ" in (collection-file-path "unit.rkt" "drracket" "private"). It
is copied directly from the search search algorithm from Wikipedia
called Knuth-Morris-Pratt, but with a fancier version of get-char that
cooperates with text%'s snip interface for more efficient linear
scans of characters.
It also generalizes the previous one by supporting searching into
embedded text% objects inside editor-snip% objects

Try building on a minimal VM, first, and then fall back to a more
general VM is that fails. For example, a minimal VM might not include
a C compiler, which can help clarify that a package will work in some
environments and not in others.
This strategy has been successful for the package-build service,
and it will hopefully cut down on spurious snapshot build failures
that happen when a VM's networking doesn't start up quickly enough.
If the target folder exists, let the user know and give up. (This
seems safer than trying to delete the folder, since there might be
other files in the folder than the original files, and the installer
doesn't currently keep a list of installed files.)
A public method definition and a private field that contains
a function are hard to distinguish without traversing the entire
class body, which caused TR to fail to detect the private field
case. TR now uses more compile-time state to precisely
distinguish the cases.
Also fixes a related bug in which TR would incorrectly handle
multiple private fields defined with a single `define-values`.
Closes PR 14788
The check that the current meta-continuation matches the captured one
would always fail (I think), since the current meta-continuation is
pruned on capture. Keep a weak link to the original meta-continuation
to enable detection of capturing a continuation that matches or
extends one that was previously captured.
Enabling sharing exposed a problem with the code that saves
continuation marks for partial sharing, since that implementation
became out of sync with the main implementation (so merge the
implementations).
