FIXME -> TODO (nothing is broken)

Let MESON take an additional "preskolemization tactic", which can be used to put the goal in definitional CNF

use definitional CNFs in Metis rather than plain CNF, following a suggestion by Joe Hurd; this *really* speeds up things -- HOL now builds 12% faster on my machine

make definitional CNF translation code more robust in the presence of existential quantifiers in the "literals"

formal framework for presentation of selected statements

Table.map replaces Table.map'

run relevance filter in a thread, to avoid blocking

add dependency of "spass" script

more elegant ML

only kill ATP threads in nonblocking mode

lower number of facts given to SInE

update docs

added "blocking" option to Sledgehammer to run in synchronous mode; sometimes useful, e.g. for testing

normalization fails on unchanged goal

prefer regular print functions over slightly low-level Term.string_of_vname;

eliminated obsolete old-style goal stack package, which was considered the main Isabelle user interface at some point;

eliminated really ancient OldGoals operations in favour of Goal.prove_internal (with its minimal checks and without normalization of result); tuned white space; tuned indentation;

make Sledgehammer's relevance filter somewhat slacker

move imperative code to where it belongs

deal with duplicates

improve new "sledgehammer_filter" action

remove useless var

added evaluation method for relevance filter

remove needless parameter

bring Sledgehammer's combinators in line with Metis's; cf. email from Larry

fiddle with the relevance filter

moved Toplevel.run_command to Pure/PIDE/document.ML; eliminated aliases of exception Toplevel.TERMINATE and Toplevel.EXCURSION_FAIL; tuned signatures;

Command.State: add reported positions to markup tree, according main message position or Markup.binding/entity/report occurrences in body; Position.Id_Range convenience;

tuned;

Node.full_index: allow command spans larger than block_size;

Document_View: repaint overview for any command change of this node (again);

refined proper_line_range (again), to make text_area_extension work with soft wwrap; NB: text_area.offsetToXY returns null for "invisible" positions;

Document state assignment indicates command change;

tuned commands_changed_actor: more precise/efficient handling of visible screen lines;

simplified/clarified Document_View.text_area_extension; tuned Document.Node.block_size, trading some space for better time;

Document.Node: significant speedup of command_range etc. via lazy full_index;

text_edits/recover_spans: reparse at least until line boundary -- increases chance of recovery for bad ML text, for example;

Command.newlines: account for physical newlines;

Toplevel.run_command: more careful treatment of interrupts stemming from nested multi-exceptions etc.; simplified Toplevel.error_msg;

tuned messages: discontinued spurious full-stops (messages are occasionally composed unexpectedly);

more careful treatment of nested multi-exceptions, collapsing cumulatively empty list to Interrupt;

Command.results: ordered by serial number;

message serial number indicates physical order;

what is hidden is hidden

hide all-too-popular constant name eq

formerly unnamed infix equality now named HOL.eq

code checking: compiler invocation happens in same directory as generated file -- avoid problem with different path representations on cygwin

Quotient Package: dont unfold mem_def, use rsp and prs instead

Quotient Package: added respectfulness and preservation lemmas for mem.

quotient package: added a list of pre-simplification rules for Ball, Bex and mem

quotient package: lemmas to be lifted and descended can be pre-simplified

renamed class/constant eq to equal; tuned some instantiations

improved deresolving of implicits

Document_View.text_area_extension: do not insist in crashing if (weak) assertion is violated;

Isabelle/jEdit property for global tooltip dismiss delay;

External_Hyperlink: proper error dialog;

Document_Mode.Line_Context: proper semantic equality/hash code avoids memory leak due to interning in org.gjt.sp.jedit.syntax.TokenMarker;

JEDIT_JAVA_OPTIONS: actors.enableForkJoin=false is supposed to enable ResizableThreadPoolScheduler, to avoid starvation of excessive amounts of future tasks etc.;

session_actor: ignore spurious TIMEOUT (again) -- probably stemming from earlier use of receiveWithin;

session_actor: await state assigment of previous change before signalling current change, and avoid crash in overrun situations;

use Future.get_finished where this is the intended meaning -- prefer immediate crash over deadlock due to promises that are never fulfilled; clarified session signalling;

Swing_Thread.now: volatile result to make double-sure;

Document_Model.token_marker: misc tuning and simplification;

added Document.Snapshot.select_markup, which includes command iteration, range conversion etc.; Markup_Tree.select: plain Iterator; misc tuning and simplification;

XML.Cache: intern property keys once and for all (again);

more careful locking of jEdit buffer;

avoid application crash due to wrong requirement -- result is joined, but change not necessarily finished due to extra map;

include Document.History in Document.State -- just one universal session state maintained by main actor; Session.command_change_buffer: thread actor ensures asynchronous dispatch; misc tuning;

volatile variables (in Scala);

non-critical output primitives -- depending on thread-safe TextIO, while races wrt. flushing should not matter;

modernized specifications;

discontinued separate Pure-ProofGeneral keywords session -- protocol commands are already defined in Pure;

discontinued broken no_warnings_CRITICAL -- global output channels must not be changed after startup initialization;

eliminated broken Output.no_warnings_CRITICAL -- context visibility does the job; modernized attribute setup;

more careful treatment of context visibility flag wrt. spurious warnings; misc tuning;

eliminated obsolete Output.no_warnings, where no warnings were produced anyway;

eliminated broken Output.no_warnings_CRITICAL -- context visibility does the job;

more careful treatment of context visibility flag wrt. spurious warnings;
