* When the data we have buffered to write to a terminal grows beyond anicm2017-04-191-3/+3
| | | | | | | | | | | | | | | | | | reasonable amount (currently width * height * 8 bytes), discard all output to the terminal and start trying to redraw periodically instead. Continue with this until the amount of data we are trying to write falls to a low level again. This helps to prevent tmux sitting on a huge buffer of data when there are processes with fast output running inside tmux but the outside terminal is slow. A new client_discarded format holds the amount of data that has been discarded due to this mechanism. The three variables (when to start this, when to stop, and how often to redraw) are basically "works for me" at the moment, this is going in to see how it goes and if it causes problems for anyone else.
* On terminals without DECSLRM, when a pane that is less than the fullnicm2017-04-181-2/+52
| | | | | | | | | | | | | | | | | | | | | with of the terminal scrolls, tmux needs to redraw the entire pane. This results in a large amount of output data which can cause slow terminals to struggle, particularly when many lines are scrolled together quickly. This can be reduced by only redrawing when tmux doesn't hold any buffered data for the terminal. If a redraw is required and data is buffered, the redraw is deferred until all that data is consumed (it is checked after every event loop, a timer is used to ensure this happens at some point). While a redraw is pending, no additional data will be written to the terminal. The redraw still happens, now it is just pushed back if it is possible it would just add more data on top of a terminal that is already behind. This both gives the terminal a chance to catch up, and allows tmux to process more scrolling (that would require additional redraws) in the meantime. Helps with a problem reported by Greg Hurrell.

* Give each client a name. This defaults to the tty name as before butnicm2017-04-051-7/+14
| | | | | | | falls back to an alternative if the tty name is not available. This is clearer than overloading the client ttyname member and allows us to remove the path stored in the tty struct, it should always be the same as the client.

* Implement "all event" (1003) mouse mode but in a way that works. Thenicm2017-02-011-7/+35
| | | | | | | | | | | main issue is that if we have two panes, A with 1002 and B with 1003, we need to set 1003 outside tmux in order to get all the mouse events, but then we need to suppress the ones that pane A doesn't want. This is easy in SGR mouse mode, because buttons == 3 is only used for movement events (for other events the trailing m/M marks a release instead), but in normal mouse mode we can't tell so easily. So for that, look at the previous event instead - if it is drag+release as well, then the current event is a movement event.

* Fix so that we work out the right pane from mouse events - we were doingnicm2016-11-241-8/+15
| | | | | | | | | | so too early, before the mouse event was necessarily valid, so could end up using the pane from the previous mouse event, or the active pane. It is important that we use the right pane now that different panes can have different key tables (for copy mode). Fixes problem reported by Greg Hurrell.

* Initial attempt to make use of left and right margins if the terminalnicm2016-11-151-1/+2
| | | | | | | supports them (that is, if it advertises itself as a VT420 - probably just xterm). These are the vertical equivalent of the scroll region and allow much faster scrolling of panes that do not take up the full width of the terminal.
* Alerts are too slow, so rather than walking all sessions and windows,nicm2016-10-191-6/+5
| | | | | | add a link of winlinks to each window and a pointer to the session to each winlink. Also rewrite the alerts processing to return to the old behaviour (alert in any window sets the flag on any winlink).

* Mass rename struct cmd_q to struct cmdq_item and related.nicm2016-10-161-5/+5
|
* Rewrite command queue handling. Each client still has a command queue,nicm2016-10-161-13/+33
| | | | | | | | | | | | | | | but there is also now a global command queue. Instead of command queues being dispatched on demand from wherever the command happens to be added, they are now all dispatched from the top level server loop. Command queues may now also include callbacks as well as commands, and items may be inserted after the current command as well as at the end. This all makes command queues significantly more predictable and easier to use, and avoids the complex multiple nested command queues used by source-file, if-shell and friends. A mass rename of struct cmdq to a better name (cmdq_item probably) is coming.

* Support double and triple clicks (they are cumulative, so double isnicm2016-10-111-9/+114

* Fundamental change to how copy mode key bindings work:nicm2016-10-111-8/+27
| | | | | | | | | | | | | | | | | | | | | | | | | The vi-copy and emacs-copy mode key tables are gone, and instead copy mode commands are bound in one of two normal key tables ("copy-mode" or "copy-mode-vi"). Keys are bound to "send-keys -X copy-mode-command". So: bind -temacs-copy C-Up scroll-up bind -temacs-copy -R5 WheelUpPane scroll-up Becomes: bind -Tcopy-mode C-Up send -X scroll-up bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up This allows the full command parser and command set to be used - for example, we can use the normal command prompt for searching, jumping, and so on instead of a custom one: bind -Tcopy-mode C-r command-prompt -p'search up' "send -X search-backward '%%'" command-prompt also gets a -1 option to only require on key press, which is needed for jumping. The plan is to get rid of mode keys entirely, so more to come eventually.
