added certify_inst, certify_instantiate;

merged

trans_tac: use theory from goal state, not the static context, which seems to be outdated under certain circumstances (why?);

proper Jinja-Slicing;

abstractions: desymbolize name hint

added numeral code postprocessor rules on type int

sos comments modified

sos documentation

Added remote-SOS changes by Philipp Meyer

Functionality for sum of squares to call a remote csdp prover

merged

updated generated document

reinserted legacy ML function

Set.UNIV and Set.empty are mere abbreviations for top and bot

explicit is better than implicit

Meson.first_order_resolve: avoid handle _; proper context for various Meson and Metis rules and tactics unified meson_tac/meson_claset_tac;

removed old global get_claset/map_claset; added local get_claset/put_claset;

eliminated METAHYPS;

Future.shutdown before loading sequentially -- workaround scheduler deadlock;

ResAxioms.neg_conjecture_clauses: proper context; let exceptions get through unhindered -- Poly/ML exception_trace will do the tracing;

neg_conjecture_clauses, neg_clausify_tac: proper context, eliminated METAHYPS; external_prover: neg_conjecture_clauses should handle TVars within goals; misc tuning;

Hilbert_Classical: sequential loading due to @{prf}, which joins within a critical section (via options);

eliminated separate Future.enabled -- let Future.join fail explicitly in critical section, instead of entering sequential mode silently;

non-critical use_thy;

future result: Synchronized.var;

added unsynchronized Synchronized.peek;

group status: Synchronized.var;

tuned;

Task_Queue.dequeue: explicit thread;

more precise treatment of scheduler_event: continous pulse (50ms) instead of flooding, which was burning many CPU cycles in spare threads;

interruptible_task: unified treatment of Multithreading.with_attributes (cf. 9f6461b1c9cc);

misc tuning;

tuned

moved obsolete same_fst to Recdef.thy

adapted doc to type of "op O"

added proof of Kleene_Algebra.star_decomp

added missing proof of RBT.map_of_alist_of (contributed by Peter Lammich)

some lemmas about maps (contributed by Peter Lammich)

"more standard" argument order of relation composition (op O)

added rail antiquotation environment, which coexists with old-style content markup;

proper header; proper structure; tuned white space;

proper context for SAT tactics; eliminated METAHYPS; tuned signatures;

moved METAHYPS to old_goals.ML (cf. SUBPROOF and FOCUS in subgoal.ML for properly localized versions of the same idea);

interruptible: Thread.testInterrupt before changing thread attributes;

wait: absorb spurious interrupts; replaced wait_timeout by explicit wait_interruptible;

scheduler: shutdown spontaneously (after some delay) if queue is empty; scheduler_check: critical, only performed after fork/enqueue; shutdown: passively wait for termination;

join_next: do not yield, even if overloaded, to minimize "running" tasks;

tuned tracing;

cancel: improved reactivity due to more careful broadcasting; internal broadcast_all;

dequeue_towards: always return active tasks; join_work: imitate worker more closely, keep active if queue appears to be blocked for the moment -- it may become free again after some worker_finished event;

merged

removed unused low-level interrupts;

tuned signature;
