into the read callback several times in succession; swap back when we
see empty buffers several times. This hopefully limits how much programs
that print a lot for a long period can monopolize tmux (like large, fast
compiling), without penalizing programs that print a lot briefly (like
most curses applications). Helps a lot for me, the actual numbers may
need tweaking later.

the state (client, session, winlink, pane) for it it before entering the

This is a requirement for having hooks on commands (for example, if you
hook "select-window -t1:2", the hook command should to operate on window
1:2 not whatever it thinks is the current window), and should allow some
other target improvements.
The old cmd_find_* functions remain for the moment but that layer will

poor idea that was fairly quickly replaced by SGR mouse input (which is
now widespread). It is impossible to tell the difference between UTF-8
and non-UTF-8 mouse input; since the mouse-utf8 option was removed tmux
has not handled it correctly in any case; and it is ridiculous to have
three different forms of mouse input.
of storing a full grid_cell with UTF-8 data and everything, store a new
type grid_cell_entry. This can either be the cell itself (for ASCII
cells), or an offset into an extended array (per line) for UTF-8
data.
This avoid a large (8 byte) overhead on non-UTF-8 cells (by far the
majority for most users) without the complexity of the shadow array we
had before. Grid memory without any UTF-8 is about half.
The disadvantage that cells can no longer be modified in place and need
to be copied out of the grid and back but it turned out to be lot less
complicated than I expected.
uint64_t and converting UTF-8 to Unicode on input and the reverse on
output. (This allows key bindings, there are still omissions - the
largest being that the various prompts do not accept UTF-8.)
around, we can't use file descriptors for the working directory because
we will be unable to pass it to a privileged process to tell it where to
read or write files or spawn children. So move tmux back to using
strings for the current working directory. We try to check it exists
with access() when it is set but ultimately fall back to ~ if it fails
at time of use (or / if that fails too).
#{=10:...} length limit, add #{t:...} to convert a time_t format to a
string, #{b:...} for basename and #{d:...} for dirname. Remove all the
foo_string time formats as they can now be replaced by "t:", for example
#{window_activity_string} becomes #{t:window_activity}.

can't do the name check every loop, because that is too expensive, and
we can't make sure it only happens infrequently because we have no idea
when the next change will happen.
but that can only happen when we have already been woken up by a read

check for bells etc anyway).

server at a time; it may be toggled or cleared with select-pane -m and
-M (the border is highlighted). A new target '~' or '{marked}' specifies
the marked pane to commands and it is the default target for the

keys. The default key bindings become the "prefix" table and -n the

irritating flaws:
a) The old way of always using the top or left if the choice is
ambiguous is annoying when the layout is unbalanced.
b) The new way of remembering the last used pane is annoying if the
layout is balanced and the leftmost is obvious to the user (because
clearly if we go right from the top-left in a tiled set of four we want
to end up in top-right, even if we were last using the bottom-right).
So instead, use a combination of both: if there is only one possible
pane alongside the current pane, move to it, otherwise choose the most
recently used of the choice.

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.
or unzoom (restored to the normal layout) if it already zoomed, bound to C-b z

off by default is a possibility).

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).

Clean up and simplify tmux command argument parsing.
Originally, tmux commands were parsed in the client process into a
struct with the command data which was then serialised and sent to the
server to be executed. The parsing was later moved into the server (an
argv was sent from the client), but the parse step and intermediate
struct was kept.
This change removes that struct and the separate parse step. Argument
parsing and printing is now common to all commands (in arguments.c) with
each command left with just an optional check function (to validate the
arguments at parse time), the exec function and a function to set up any
key bindings (renamed from the old init function).
This is overall more simple and consistent.
There should be no changes to any commands behaviour or syntax although
as this touches every command please watch for any unexpected changes.

Originally, tmux commands were parsed in the client process into a
struct with the command data which was then serialised and sent to the
server to be executed. The parsing was later moved into the server (an
argv was sent from the client), but the parse step and intermediate
struct was kept.
This change removes that struct and the separate parse step. Argument
parsing and printing is now common to all commands (in arguments.c) with
each command left with just an optional check function (to validate the
arguments at parse time), the exec function and a function to set up any
key bindings (renamed from the old init function).
This is overall more simple and consistent.
There should be no changes to any commands behaviour or syntax although
as this touches every command please watch for any unexpected changes.
Move the user-visible parts of all options (names, types, limit, default
values) together into one set of tables in options-table.c. Also clean
up and simplify cmd-set-options.c and move a common print function into
option-table.c.
and supports larger terminals than the older way.
If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
UTF-8 terminals. The option defaults to on if LANG etc are set in the
same manner as the utf8 option.

Store sessions in an RB tree by name rather than a list, this is tidier
and allows them to easily be shown sorted in various lists
(list-sessions/choose-sessions).
Keep a session index which is used in a couple of places internally but
make it an ever-increasing number rather than filling in gaps with new
sessions.
Unify the way sessions are used by callbacks - store the address and use
the reference count, then check it is still on the global sessions list
in the callback.

There is somewhere that WINDOW_HIDDEN is getting set when it shouldn't
be and I can't find it, but the flag itself is a useless optimisation
that only applies to automatic-resize windows, so just dispose of it
entirely.
Fixes problems reported by Nicholas Riley.

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.

Use UTF-8 line drawing characters on UTF-8 terminals. Fixes some stupid
terminals (I'm looking at you, putty) which disable the vt100 ACS mode
switching sequences in UTF-8 mode.
Also on terminals without ACS at all, use ASCII equivalents where
obvious.

Add -n and -p flags to switch-client to move to the next and previous
session (yes, it doesn't match window/pane, but so what, nor does
switch-client).
Based on a diff long ago from "edsouza".
Do not call event_del() for signals after fork(), just use sigaction()
directly instead - calling libevent functions after fork() w/o
event_reinit() is a bad idea, even if in this case it was harmless.
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.

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.

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.
Custom layouts. list-windows command displays the layout as a string (such as
"bb62,159x48,0,0{79x48,0,0,79x48,80,0}") and it can be applied to another
window (with the same number of panes or fewer) using select-layout.
Send all three of stdin, stdout, stderr from the client to the server, so that
commands can directly make use of them. This means that load-buffer and
save-buffer can have "-" as the file to read from stdin or write to stdout.
This is a protocol version bump so the tmux server will need to be restarted
after upgrade (or an older client used).
Store the current working directory in the session, change the default-path
option to default to empty and make that mean that the stored session CWD is
used.
Setting the cmdlist pointer in the bind-key to NULL to prevent it being freed
after the command is executing is bogus because it may still be needed if the
same command is going to be executed again (for example if you "bind-key a
bind-key b ..."). Making a copy is hard, so instead add a reference count to
the cmd_list.
While here, also print bind-key -n and the rest of the flags properly.

Fix problems with window sizing seen by Raghavendra D Prabhu when
starting tmux from .xinitrc.
One of the very few things the server relies on the client for now is to
pass through a message on SIGWINCH, but there is a condition where
potentially a SIGWINCH may be lost during the transition from unattached
(main.c) to attached (client.c). So trigger a size change immediately
after the client installs its SIGWINCH handler.
Also, when the terminal is resized, reset the scroll region and cursor
position. Previously, we were clearing our saved idea of these, but in
fact some terminals do not reset them on resize, so this caused problems
during redraw.
While here make a resize to the same size not cause a redraw and rename
the tmux.out output log file to include the tmux PID.
When the mode-mouse option is on, support dragging to make a selection
in copy mode.
Also support the scroll wheel, although xterm strangely does not ignore
it in application mouse mode, causing redraw artifacts when scrolling up
(other terminals appear to be better behaved).

This allows send-key to work properly for manipulating copy mode from
outside tmux.

Identical behaviour to select-prompt can now be obtained with
command-prompt, so remove select-prompt and change ' to be bound to
command-prompt -p index "select-window -t :%%".
Make signal handler setup/teardown two common functions instead of six,
and reset SIGCHLD after fork to fix problems with some shells. From
Romain Francoise.
Permit keys in copy mode to be prefixed by a repeat count, entered with
[1-9] in vi mode, or M-[1-9] in emacs mode.
From Micah Cowan, tweaked a little by me.
copy mode uses the real screen as backing and if it is updated while copying,
strange things can happen. So, freeze reading from the pty while in copy mode.
Instead of bailing out on the first configuration file error, carry on,
collecting all the errors, then start with the active window in more mode
displaying them.
vi-style B, W and E keys in copy mode to navigate between words treating only
spaces as word separators. Also add . to the list of word separators for
standard word navigation.
From Micah Cowan, tweaked slightly by me.
Add "server options" which are server-wide and not bound to a session or
window. Set and displayed with "set -s" and "show -s".
Currently the only option is "quiet" (like command-line -q, allowing it to be
set from .tmux.conf), but others will come along.

Massive spaces->tabs and trailing whitespace cleanup, hopefully for the last
time now I've configured emacs to make them displayed in really annoying
colours...
Eliminate duplicate code and ease the passage for server-wide options by adding
a -w flag to set-option and show-options and making setw and showw aliases to
set -w and show -w.
Note: setw and showw are still there, but now aliases for set -w and show -w.
