b8bda67f30 Don't blindly increase offsets by the return value of snprintf, if there
wasn't enough space this will go off the end. Instead clamp to the
available space. Fixes crash reported by Julien Rebetez.

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.

d1e6ce2672 Add functions to allocate and free command contexts rather than doing it
all on the stack.

5385a9bb34 Add a queue of notifys and a way to turn them off and on (we do not want
notifys to happen during some commands). Based on code from George
Nachman.

ede8312d59 Make command exec functions return an enum rather than -1/0/1 values and
add a new value to mean "leave client running but don't attach" to fix
problems with using some commands in a command sequence. Most of the
work by Thomas Adam, problem reported by "jspenguin" on SF bug 3535531.

df912e3540 xfree is not particularly helpful, remove it. From Thomas Adam. 2012-07-10 11:53:01 +00:00

2942eca895 Add a skeleton mode to tmux (called "control mode") that let's tmux
commands be sent and output received on stdout. This can be used to
integrate with other terminal emulators and should allow some other
things to be made simpler later. More to come so doesn't do much yet and
deliberately not documented.

34d05ea7cd We now send argv to the server after parsing it in the client to get the
command, so the client should not modify it. Instead, take a copy. Fixes
parsing command lists, reported by mcbride@.

42e2413978 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.

Fixes problem reported by mcbride@.

e16b7b8399 Reset output functions too when changing client after attaching, to
avoid crash if a command in a sequence after new/attach causes output.

8a37a1cc2d Don't stop parsing command sequences when a command requests the client to
stick around (attach-session/new-session).

34a82e7629 Make all messages sent between the client and server fixed size.
This is the first of two changes to make the protocol more resilient and less
sensitive to other changes in the code, particularly with commands. The client
now packs argv into a buffer and sends it to the server for parsing, rather
than doing it itself and sending the parsed command data.

As a side-effect this also removes a lot of now-unused command marshalling
code.

Mixing a server without this change and a client with or vice versa will cause
tmux to hang or crash, please ensure that tmux is entirely killed before
upgrading.

35876eaab9 Import tmux, a terminal multiplexor allowing (among other things) a single
terminal to be switched between several different windows and programs
displayed on one terminal be detached from one terminal and moved to another.
