Although "macOS" is the correct name for Apple's current desktop OS,
we've decided to go with "Mac OS" to cover all of Apple's Unix-like
desktop OS versions. The label "Mac OS" is more readable, clear in
context (i.e., unlikely to be confused with the Mac OSes that
proceeded Mac OS X), and as likely to match Apple's future OS names
as anything.
Along with the `PLT_COMPILED_FILE_CHECK` environment variable, allows
the timestamp check to be disabled when deciding whether to use a
compiled bytecode file.
In accomodating this change, `raco make` and `raco setup` in all modes
check whether the SHA1 hash of a module source matches the one
recorded in its ".dep" file, even if the timestamp on the bytecode
file is newer. (If the compile-file check mode is 'exists, the
timestamp is completely ignored.)
When custom categories are used in older versions, raco setup will
report a warning, but the documentation will still appear under the
Miscellaneous section. Thus, this is a backwards compatible
implementation of the idea.
On my machine, the sync path was sometimes triggered for "htdp-ptr".
(I'm not sure why; progress toward determinsitic bytecode might
be relevant.) Adjust the trigger for sync mode to check that the
needed "provides.sxref" file exists.
Rending a document can deserialize values, which can load modules
that would otherwise not be loaded by Scribble, so render each
document with a fresh namespace that is discarded after rendering.
find-relative-path expects a simple-form-path, but according to the documentation PLTUSERHOME as propagated by find-user-pkgs-dir must only be a complete-path?
Without this building of the documentation fails if PLTUSERHOME contains ".."
