d60663ea86 Some applications like vi(1) and tmux until 10 minutes or so ago, do not
redraw on SIGWINCH if the size returns to the original size between the
original SIGWINCH and when they get around to calling TIOCGWINSZ. So use
the existing resize timer to introduce a small delay between the two
resizes.

ea6428a5d2 It is not OK to ignore SIGWINCH if SIOCGWINSZ reports the size has
unchanged, because it may have changed and changed back in the time
between us getting the signal and calling ioctl(). Always redraw when we
see SIGWINCH.

80c6b487dc Because we defer actually resizing applications (calling TIOCSWINSZ)
until the end of the server loop, tmux may have gone through several
internal resizes in between. This can be a problem if the final size is
the same as the initial size (what the application things it currently
is), because the application may choose not to redraw, assuming the
screen state is unchanged, when in fact tmux has thrown away parts of
the screen, assuming the application will redraw them.

To avoid this, do an extra resize if the new size is the same size as
the initial size. This should force the application to redraw when tmux
needs it to, while retaining the benefits of deferring (so we now resize
at most two times instead of at most one - and only two very rarely).

Fixes a problem with break-pane and zoomed panes reported by Michal
Mazurek.

3b35daacf7 If the current screen was complex enough, it was possible to make redraw
itself hit the "terminal can't keep up" check. To avoid this, record how
much data we send during redraw (we know we will be starting with 0) and
skip the check until it has been flushed. GitHub issue 912.

d52f579fd5 Up to now, tmux sees \033\033[OA as M-Up and since we turned on
xterm-keys by default, generates \033[1;3A instead of
\033\033[OA. Unfortunately this confuses vi, which doesn't understand
xterm keys and now sees Escape+Up pressed within escape-time as Escape
followed by A.

The issue doesn't happen in xterm itself because it gets the keys from X
and can distinguish between a genuine M-Up and Escape+Up.

Because xterm can, tmux can too: xterm will give us \033[1;3A (that is,
kUP3) for a real M-Up and \033\033OA for Escape+Up - in fact, we can be
sure any \033 preceding an xterm key is a real Escape key press because
Meta would be part of the xterm key instead of a separate \033.

So change tmux to recognise both sequences as M-Up for its own purposes,
but generate the xterm version of M-Up only if it originally received
the xterm version from the terminal.

This means we will return to sending \033\033OA instead of the xterm key
for terminals that do not support xterm keys themselves, but there is no
practical way around this because they do not allow us to distinguish
between Escape+Up and M-Up. xterm style escape sequences are now the de
facto standard for these keys in any case.

issue 907.

0ccfb61bb0 In order that people can use formats like #D in #() in the status line
and not have to wait for an update when they change pane, we allow
commands to run more than once a second if the expanded form
changes. Unfortunately this can mean them being run far too often
(pretty much continually) when multiple clients exist, because some
formats (including #D) will always differ between clients.

To avoid this, give each client its own tree of jobs which means that
the same command will be different instances for each client - similar
to how we have the tag to separate commands for different panes.

2c0f826c36 Mouse bindings and hooks set up an initial current state when running a
command. This is used for the session, window and pane for all commands
in the command sequence if there is no -t or -s.

However, using it for all commands in the command sequence means that if
the active pane or current session is changed, subsequent commands still
use the previous state. So make commands which explicitly change the
current state (such as neww and selectp) update it themselves for later
commands. Commands which may invalidate the state (like killp) are
already OK because an invalid state will be ignored.

Also fill in the current state for all key bindings rather than just the
mouse, so that any omissions are easier to spot.

92a77e7654 It is annoying that the copy mode key table (or any other key table)
will suppress root key table bindings. So change to always check the
root table if no binding is found in the current table (whether it be
the prefix table from pressing the prefix or the copy mode table from a
pane).

A root key binding can be blocked by binding the key to a command that
does nothing (like send-keys with no arguments).

fa6deb5866 When the data we have buffered to write to a terminal grows beyond a
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.

8c8ce08d79 On terminals without DECSLRM, when a pane that is less than the full
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.

dd0c814779 Implement "all event" (1003) mouse mode but in a way that works. The
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.

ddc4512d2e Rewrite command queue handling. Each client still has a command queue,
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.

76d6d3641f Fundamental change to how copy mode key bindings work:
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.

bf635e7741 Rewrite of tmux mouse support which was a mess. Instead of having
options for "mouse-this" and "mouse-that", mouse events may be bound as
keys and there is one option "mouse" that turns on mouse support
entirely (set -g mouse on).

See the new MOUSE SUPPORT section of the man page for description of the
key names and new flags (-t= to specify the pane or window under mouse
as a target, and send-keys -M to pass through a mouse event).

The default builtin bindings for the mouse are:

    bind -n   MouseDown1Pane select-pane -t=; send-keys -M
    bind -n MouseDown1Status select-window -t=
    bind -n   MouseDrag1Pane copy-mode -M
    bind -n MouseDrag1Border resize-pane -M

To get the effect of turning mode-mouse off, do:

    unbind -n MouseDrag1Pane
    unbind -temacs-copy MouseDrag1Pane

The old mouse options are now gone, set-option -q may be used to
suppress warnings if mixing configuration files.

282c5f9644 Alter how tmux handles the working directory to internally use file
descriptors rather than strings.

- Each session still has a current working directory.

- New sessions still get their working directory from the client that
  created them or its attached session if any.

- New windows are created by default in the session working directory.

- The -c flag to new, neww, splitw allows the working directory to be
  overridden.

- The -c flag to attach let's the session working directory be changed.

- The default-path option has been removed.

To get the equivalent to default-path '.', do:

        bind c neww -c $PWD

To get the equivalent of default-path '~', do:

        bind c neww -c ~

This also changes the client identify protocol to be a set of messages rather
than one as well as some other changes that should make it easier to make
backwards-compatible protocol changes in future.

bound to C-b z by default. The pane is unzoomed on pretty much any
excuse whatsoever.

We considered making this a new layout but the requirements are quite
different from layouts so decided it is better as a special case. Each
current layout cell is saved, a temporary one-cell layout generated and
all except the active pane set to NULL.

20636d956d Add a command queue to standardize and simplify commands that call other
commands and allow a command to block execution of subsequent
commands. This allows run-shell and if-shell to be synchronous which has
been much requested.

Each client has a default command queue and commands are consumed one at
a time from it. A command may suspend execution from the queue by
returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() -
for example run-shell does this from the callback that is fired after
the job is freed.

When the command queue becomes empty, command clients are automatically
exited (unless attaching). A callback is also fired - this is used for
nested commands in, for example, if-shell which can block execution of
the client's cmdq until a new cmdq becomes empty.

Also merge all the old error/info/print functions together and lose the
old curclient/cmdclient distinction - a cmdq is bound to one client (or
none if in the configuration file), this is a command client if
c->session is NULL otherwise an attached client.

db7a89b1ee Simplify the way jobs work and drop the persist type, so all jobs are
fire-and-forget.

Status jobs now managed with two trees of output (new and old), rather
than storing the output in the jobs themselves. When the status line is
processed any jobs which don't appear in the new tree are started and
the output from the old tree displayed. When a job finishes it updates
the new tree with its output and that is used for any subsequent
redraws. When the status interval expires, the new tree is moved to the
old so that all jobs are run again.

This fixes the "#(echo %H:%M:%S)" problem which would lead to thousands
of identical persistent jobs and high memory use (this can still be
achieved by adding "sleep 30" but that is much less likely to happen by
accident).

04b32fa734 Don't reset the activity timer for unattached sessions every second,
this screws up the choice of most-recently-used. Instead, break the time
update into a little function and do it when the session is attached.

51487ed22f Track the last session for a client and add a flag to switch-client and
a key binding (L) to move a client back to its last session.

7ce77ffc9c Make the prompt history global for all clients which is much more useful than per-client history. 2010-12-11 16:05:57 +00:00

f56b4ec2ff Trying to set FD_CLOEXEC on every fd is a lost cause, just use
closefrom() before exec.

9a7cde0c9b Two new options:
- server option "exit-unattached" makes the server exit when no clients
  are attached, even if sessions are present;

- session option "destroy-unattached" destroys a session once no clients
  are attached to it.

These are useful for preventing tmux remaining in the background where
it is undesirable and when using tmux as a login shell to keep a limit
on new sessions.

c2822ca119 Do not need to dup() the tty fd sent from the client because it is
already dup()d again later. Fixes a leak seen by espie@.

8363e31953 Change the way backoff works. Instead of stopping reading from the pty
when the client tty backs up too much, just stop updating the tty and
only update the internal screen. Then when the tty recovers, force a
redraw.

This prevents a dodgy client from causing other clients to go into
backoff while still allowing tmux to be responsive (locally) when seeing
lots of output.

c87187f913 When changing so that the client passes its stdout and stderr as well as
stdin up to the server, I forgot one essential point - the tmux server
could now be both the producer and consumer. This happens when tmux is
run inside tmux, as well as when piping tmux commands together.

So, using stdio(3) was a bad idea - if sufficient data was written, this
could block in write(2). When that happened and the server was both
producer and consumer, it deadlocks.

Change to use libevent bufferevents for the client stdin, stdout and
stderr instead. This is trivial enough for output but requires a
callback mechanism to trigger when stdin is finished.

This relies on the underlying polling mechanism for libevent to work
with whatever devices to which the user could redirect stdin, stdout or
stderr, hence the change to use poll(2) over kqueue(2) for tmux.

b9c873cdaa Return the command client return code with MSG_EXIT now that MSG_ERROR and
MSG_PRINT are unused.

New clients should be compatible with old tmux servers but vice versa may print
an error.
