1063e5d0e4 Sync OpenBSD patchset 248:
imsg closes the fd after sending, so dup() STDIN_FILENO before passing it to
the parent, otherwise TIOCGWINSZ will fail when the window is resized (that
could actually be moved into the server but this is more future-proof and
avoids breaking the protocol).

7f77c395e3 Sync OpenBSD patchset 247:
Initialise log_fd to -1, prevents spurious disconnection of the client when it
ends up as fd 0 (likely if the server is started with "tmux start").

Also add some extra debugging messages to server.c.

e2a18894b3 Sync OpenBSD patchset 246:
Have the client pass its stdin fd to the server when identifying itself and
have the server use that rather than reopening the tty. If the fd isn't given,
use the old behaviour (so no need for a version change).

This allows tmux to be used as the shell, so also change so that when working
out the command to execute if default-command is empty (the default), tmux will
try not execute itself.

b402cef338 Adjust imsg changes to the portable version due to OpenBSD patchset 243. 2009-08-14 21:13:48 +00:00

a9b6bfdddd Sync OpenBSD patchset 243:
Switch tmux to use imsg. This is the last major change to make the
client-server protocol more resilient and make the protocol versioning work
properly. In future, the only things requiring a protocol version bump will be
changes in the message structs, and (when both client and server have this
change) mixing different versions should nicely report an error message.

As a side effect this also makes the code tidier, fixes a problem with the way
errors reported during server startup were handled, and supports fd passing
(which will be used in future).

Looked over by eric@, thanks.

Please note that mixing a client with this change with an older server or vice
versa may cause tmux to crash or hang - tmux should be completely exited before
upgrading.

Infrastructure and commands to manage the environment for processes started
within tmux.

There is a global environment, copied from the external environment when the
server is started and each session has an (initially empty) session
environment which overrides it.

New commands set-environment and show-environment manipulate or display the
environments.

A new session option, update-environment, is a space-separated list of
variables which are updated from the external environment into the session
environment every time a new session is created - the default is DISPLAY.

Change the way the grid is stored, previously it was:

- a two-dimensional array of cells;
- a two-dimensional array of utf8 data;
- an array of line lengths.

Now it is a single array of a new struct grid_line each of which represents a
line and contains the length and an array of cells and an array of utf8 data.

This will make it easier to add additional per-line members, such as flags.

5b56ea1816 Sync OpenBSD patchset 225:
If there is an error in the configuration file, don't just exit(1) as this can
cause the client to hang. Instead, send the error message, then mark the client
as bad and start a normal shutdown so the server exits once the error is
written.

This also allows some code duplicating daemon(3) to be trimmed and logging to
begin earlier.

Prompted by Theo noticing the behaviour on error wasn't documented.

If colours are not supported by the terminal, try to emulate a coloured
background by setting or clearing the reverse attribute.

This makes a few applications which don't use the reverse attribute themselves
a little happier, and allows the status, message and mode options to have
default attributes and fg/bg options that work as expected when set as reverse.
