Register a button as a default button every time that it is shown,
so that multiple buttons in a frame can have the 'border style
(as long as only one is shown at a time).
On Cocoa, a view's `drawRect:' method can be called from a
heartbeat thread that animates controls. Such a call happens
rarely for a `canvas%' or other class where `drawRect:'
is overridden, but since it can happen, ensure that the
callback runs on the Racket thread.
This requires extending the ->optkey type constructor to support rest
arguments, and fixing the keyword function type generation code.
Testing is still limited because there's no parsing for such types.
That will be handled in a later commit.
Fix a problem at the boundary of DWARF-driven backtrace
and frame-driver backtrace, as well as handling of the
JIT's different internal calling conventions.
Also, allow crossing back from frame-driven to DWARF-driven.
... when PWD is defined and when it refers to the same directory
as the result of getcwd().
A shell sets PWD before starting Racket to communicate a preferred
way of referring to the current directory, which may involve soft
links that are not reflected in getpwd().
With this patch racket will never grow beyond of the defaults limits of
the OS and also it doesn't limit the stack size to a fixed value.
Merge to v5.3.4
The output of "/proc/cpuinfo" seems wrong for a Raspberry Pi running
the latest Raspian, because it claims ARMv6-compatible but also claims
"thumb" as a feature and 7 as the CPU architecture. Use the C compiler's
configuraton, instead, which is relatively straightforward and drops
code that will turn out to be dead.
When a collection disappears, then documentation and metadata
cross-references need fixing up based on everything that remains
available, even though other setup actions are confined to
collections that are specifically relevant to the packages. The
new `--tidy' mode takes care of that.
Package installation now also provides `--avoid-main' when working
with packages in a scope other than installation scope, and `raco
setup' now better respects `--avoid-main' to avoid creating
executables or re-running documentation.
Also, revise the `raco' documentation to better orient it toward the
package manager.
That is, limit the ending `raco setup' to the same collections
as the corresponding `raco pkg install' (droppping collections
that no longer exist afterward, of course).
... for the purpose of "populate 'compiled' directories" --- but only if
the user has write permission for the package directory.
This change may or may not be a good idea. The idea is that installed
packages generally should be treated in the same way as the main
"collects" tree (e.g., avoiding debugging instrumentation), but if you
happen to be developing a package, then you want it treated like things
that are not in the main "collects" tree. So, how do you pick? Maybe
opening a file in the package is a good way to pick.
If DrRacket decides to skip a file for "populate compiled",
then there may exist a file in "compiled/drracket", anyway,
or there may be such a file for some depenency of the skipped
file. Before this patch, that situation was considered to be a
broken installation, and things would go bad in the likely
case that the "compiled/drracket" files were out of date.
To avoid that problem, parameterize `used-compiled-file-paths'
to drop the DrRacket "populate compiled" target while loading
the skipped file.
This change sets up a more selective "populate compiled" where
a package's modules might switch between eligible and
ineligible for compilation by DrRacket.
