Instead of potentially waiting ten minutes in the problematic case, we
scry out the next timer from behn and set to that (if we haven't set
a new timer while we were waiting for the scry).
No longer abuse the desk field, instead making use of the path. Reject
any scries outside of the local ship, empty desk and current time as
invalid.
Expose ducts only under a debug endpoint, nothing else should care about
being able to inspect them.
Add scry endpoints for the very next timer (if any), and all timers up
to and including a specified timestamp.
Tries to get a scry result from a /vanecare/desk/path formatted path,
and jams the result to disk (.urb/put/) if it succeeds.
Optionally use -Y to specify a name for the resulting file.
This adds a new build stage called combine which takes the results
of the previous compile builds and packages them up into one
release tarball per platform.
This is a convenient way to count memory usage of noun by simplying
running `(jam 1.337 noun-1 noun-2 ... ~)`. This should
be a hint, but for debugging this is sufficient.
With these changes, about 90% less memory and 15% less time is needed to
compile hoon.hoon. The produced noun is within 3% of the same size,
which suggests this results in little if any duplication.
These are three of the four most commonly hit +ut jets. The other is
+nest, which cannot be un-memoized without taking much longer to compile
(it didn't finish in my test). These four jets combined for 2.3 million
out of the 2.4 million cache entries, the other +ut jets combine for
less than 100k, and literal ~+ accounted for about 50k entries.
This also caps the memo cache at 50k entries. Even with these jets not
memoized, the memo cache grows to 357k entries and 122 MB. Capping at
50k entries has no effect on time and reduces memory usage of the hash
table to about 25MB. Entries are reclaimed with the clock algorithm,
which seems to be sufficient for this use.
Adds a few functions to count the size of nouns in the current road.
Since this marks the nouns (high bit of refcount), you need to
"discount" them immediately after to unmark them. Parallel functions
exist for the counting the size of a hashtable.
It would nice to hook this up to a hint, but these are useful to have
available to run in the debugger or by inserting callsites as necessary.
It's also possible to hook them up to the +jam jet gated on a special
value.
