| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | real-time"): because we use monotonic time in all wait functions, so to avoid too long wait by the absolute timers (to be able to trigger it) if time jumped to the expected absolute time, just let block for maximal 1 second if absolute timers available. test-cases: time-jumps (TIP #302) test covered now. Note: on some platforms it is only possible if the user has corresponding privileges to change system date and time. Ex.: sudo LD_LIBRARY_PATH=. ./tclsh ../tests/timer.test -match timer-20.*

| | | | | | | | | | | | | | | | | | | | | | | | | | | | windows and unix now, TIP #302 fully implemented now); Usage of monotonic time instead of adjustment via timeJump/timeJumpEpoch is more precise and effective. New sub-command "clock monotonic" to provide monotonic time facility for tcl-level.

| * | | Merge branch 'fix-busy-prompt-timers' into event-perf-branch: sebres2017-07-031-34/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Amend to timer-marker: dualize special state of timer-marker (to differentiate between timer generations), so: INT2PTR(-1) - exec immediate (marker reached); INT2PTR(-2) - check in the next-cycle (marker reached only if no other events available); Avoids permanent busy execution of prompt-events (always busy in timer), if they regenerate itself continuously for waiting for other events (like writable/readable), see e. g. socket-2.12.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | *nix more "RTS" resp. NRT-capable): - more precise waiting now (e.g. still microseconds by time up to 0.005 ms), important since after/vwait accepting microseconds (double); - avoids too long waiting on *nix wait/sleep primitives, e. g. by `timerate {vwait 0 a}` - 1.5µs now vs. 31.9µs before; - extended with new internal function TclpSleep (in contrast to Tcl_Sleep accept Tcl_Time, so microseconds);

| | | | | | | | | | | | | | | | | | | | | | | | | | | | avoid busy-wait if the rest of wait-time too small and can be neglected); TMR_RES_TOLERANCE can be defined to use wait-tolerance on *nix platforms (currently windows only as relation resp. deviation between default timer resolution 15.600 in exact milliseconds, means 15600/15000 + small overhead); Decreasing of TMR_RES_TOLERANCE (up to 0) makes tcl more "RTS" resp. NRT-capable (very precise wait-intervals, but more CPU-hungry).
| * | | [win] fallback to replace C++ keyword "inline" with C keyword "__inline" sebres2017-07-031-0/+10
| | | | | | | | | | | | | | | | | | | | Otherwise depending on the VC-version, context, include-order it can cause: error C2054: expected '(' to follow 'inline'

| | | | | | | | | | | | | | | | nonsignaled after wake-up), avoids unwanted reset if wake-up for some other reasons (timeout/aio/message).

| * | | dynamic increase of timer resolution corresponding wait-time; sebres2017-07-036-74/+386
| | | | | | | | | | | | | | | | non-blocking wait for event - if block-time set outside an event source traversal, use it as timeout, so can return with result 0 (no events);
| * | | [enhancement] extend "vwait" with same options as "update", new syntax ↵sebres2017-07-036-89/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "vwait ?options? ?timeout? varname". some small improvements and fixing: - Tcl_DoOneEvent can wait for block time that was set with Tcl_SetMaxBlockTime outside an event source traversal, and stop waiting if Tcl_SetMaxBlockTime was called outside an event source (another event occurs and interrupt waiting loop), etc; - safer more precise pre-lookup by options (use TclObjIsIndexOfTable instead of simply comparison of type with tclIndexType); test cases extended to cover conditional "vwait" usage;

| | | | | | | | | | | | | | | | | | | | | | | | | | | | (introduced threshold to prevent sourcing resp. waiting for new events by no-wait). [enhancement] new event type introduced: TCL_ASYNC_EVENTS, command "update" becomes options to process only specified types, resp. to bypass some event types (including -idle/-noidle that in opposite to "idletasks" does not included window events); test cases extended.

| | | | | | | | | | | | | | | | | | | | | | | | process pending events only (without wait), negative value equivalent execution of "vwait" without timeout (infinite); test cases fixed and extended;
| * | | [performance] much better handling for timer events within Tcl_ServiceEvent ↵sebres2017-07-034-138/+51
| | | | | | | | | | | | | | | | | | | | | | | | using timer marker in the queue and direct call of TclServiceTimerEvents if marker reached (instead of continuous adding handler event, polling it in the queue and removing hereafter); this provides double performance increase in the service cycle;
