2012-09-01 wenzelm 2012-09-01 central management of forked goals wrt. transaction id; clarified stable_exec_id: consider ragular failure as stable; more robust counting of forked proofs, with global reset after cancellation due to document editing;
2012-08-30 wenzelm 2012-08-30 refined treatment of forked proofs at transaction boundaries, including proof commands (see also 7ee000ce5390); stretched meaning of Goal.parallel_proofs to enable future_terminal_proofs in interactive document model, despite its lack for regular forking of proofs;

2012-08-11 wenzelm 2012-08-11 vacuous execution after first malformed command;
2012-08-10 wenzelm 2012-08-10 apply all text edits to each node, before determining the resulting doc_edits -- allow several iterations to consolidate spans etc.; expand Clear edit before sending to prover; at most one full reparse of each node;
2012-07-27 wenzelm 2012-07-27 even more permissive approximation of master_dir, which is only required to access external resources ('uses' etc.);

2012-04-20 wenzelm 2012-04-20 always revisit nodes independently of "required" flag, which may change during editing -- avoid "bloodbath effect" when changing perspective while loading;
2012-04-20 wenzelm 2012-04-20 tuned;
2012-04-20 wenzelm 2012-04-20 builtin timing for main operations;
2012-04-11 wenzelm 2012-04-11 tuned;
2012-04-11 wenzelm 2012-04-11 just one dedicated execution per document version -- NB: non-monotonicity of cancel always requires fresh update; explicit terminate_execution; tuned source structure;

2012-04-09 wenzelm 2012-04-09 more explicit last exec result;
2012-04-09 wenzelm 2012-04-09 dynamic propagation of node "updated" status, which is required to propagate edits and re-assigments and allow direct memo_result; discontinued odd "touched" field -- check given edits directly;
2012-04-09 wenzelm 2012-04-09 tuned;
2012-04-09 wenzelm 2012-04-09 simplified Future.cancel/cancel_group (again) -- running threads only; more robust update/cancel_execution: full join_tasks of group before exec state assignment; tuned signature;

2012-04-05 wenzelm 2012-04-05 less ambitious memo_eval, since memo_result is still not robust here;
2012-04-05 wenzelm 2012-04-05 less aggressive discontinue_execution before document update, to avoid unstable execs that need to be re-assigned;
2012-04-05 wenzelm 2012-04-05 more explicit memo_eval vs. memo_result, to enforce bottom-up execution; edit of perspective touches node superficially, to ensure revisit after update;
2012-04-05 wenzelm 2012-04-05 Command.memo including physical interrupts (unlike Lazy.lazy); re-assign unstable exec, i.e. reset interrupted transaction; node result as direct exec -- avoid potential interrupt instability of;
2012-04-05 wenzelm 2012-04-05 tuned;
2012-04-04 wenzelm 2012-04-04 tuned -- NB: get_theory still needs to apply Lazy.force due to interrupt instabilities;

2012-04-04 wenzelm 2012-04-04 tuned;
