Modern OS configurations likely use an even larger buffer size, and
making it small can have substantial negative performance effects
(e.g., with PostgreSQL over TCP).
When AC_PROG_CC picks GCC, move its selection of CFLAGS
into CPPFLAGS, so that preprocessing will have the same
optimization and debugging flags as compilation.
Arguably, AC_PROG_CC plus AC_PROG_CPP should do that
soemhow, but it's understandable that the autoconf
implementers didn't cover the possibility of
preprocessing that changes with the optimization level.
Closes#945
- Coalesce repeated use of the same predicate.
- Fix scoring of Exact patterns, and scoring generally.
- Use `OrderedAnd` where needed.
- Guarantee that `and` patterns match in order.
- Thread bound variable information properly in GSeq compilation.
- Warn when variables are used non-linearly with `...`
(making this behave properly was not backwards compatible).
Closes#952, which now runs in <1ms and make it a test case.
Also add margin note about `?` patterns and multiple calls.
Before consulting a catalog, etc., check whether a given package name
is currently installed. The new check applies only if a scope is
specified, since scope inference implies the check already.
When `local-require` is used in a non-phase-0 position and it is
`expand`ed (as opposed to compiled directly), then the generated
`#%require` form had the wrong binding phase.
Merge to v6.2
In many use cases the length of the vector is fixed and know,
so we are sure that make-vector will not raise an error and
we can recognize these expressions as omittable and drop
them when the result is ignored.
The result of some procedures is a vector, but they are not omittable
because they may rise an error. With the recent changes of the
predicate reduction these cases are correctly handled.
Adds a sealing and unsealing function to attach (or detach)
seals onto a class via impersonator properties. Since these
properties override, they do not accumulate wrappers.
Calling seal multiple times will still accumulate multiple seal
values inside the property.
A sealed class cannot be instantiated and a subclass may not
add class members that match any of the sealed names in its
sealed parent.
These functions are intended for use by TR's `sealing->/c`
contract, but are parameterized over checking functions and
could be used for other purposes.
