2013-10-10Alter how tmux handles the working directory to internally use filenicm
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.

2013-08-21Remove the barely-used and unnecessary command check() function.Nicholas Marriott
2013-03-24Add a command queue to standardize and simplify commands that call otherNicholas Marriott
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.

Instead of passing stdin/stdout/stderr file descriptors over imsg and handling them in the server, handle them in the client and pass buffers over imsg. This is much tidier for some upcoming changes and the performance hit isn't critical. The tty fd is still passed to the server as before. This bumps the tmux protocol version so new clients and old servers are incompatible.

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.

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.

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).

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.

2009-07-14Having fixed flags for single-character getopt options is a bit hard toNicholas Marriott
maintain and is only going to get worse as more are used. So instead, add a new uint64_t member to cmd_entry which is a bitmask of upper and lowercase options accepted by the command. This means new single character options can be used without the need to add it explicitly to the list.
