Marc André Tanner bb7e4e77f4 Remove MSG_REDRAW it was actually never sent by the client 2018-03-18 15:06:31 +01:00
Marc André Tanner 8964601fe1 Use fixed size integer types in protocol messages 
This should make it possible to connect with a 32bit client to a 64bit
server. This might also make it possible to forward the abduco socket
over SSH as described in #25. Different endianness are not supported at
this time.

This is a breaking protocol change. Make sure to use the same version
as client and server (anything else is unsupported anyway!).

Marc André Tanner 5b9fcf5e52 Revert "Set sticky bit on socket" 
This reverts commit 15ae398ea5.

Setting the sticky bit on a file is not really portable and
causes more problems than it solves.

The reason why this was done in the first place, is that the
XDG Base Directory Specification states that files with the
sticky bit set should not be touched by periodic cleanup
procedures.

Close #13

Marc André Tanner 577ae6ae7a Slightly tweek communication protocol for -l option 2016-01-03 12:03:02 +01:00
Luke Clifton 1fcd6e4f44 Added -l option to move clients to the bottom of the stack. 
This means it wont take control over the window size until
it is the last remaining one, unless another client connects
with the -l option set at a later time.

Marc André Tanner 15ae398ea5 Set sticky bit on socket 
According to the XDG Base Directory Specification this should
prevent the file from being deleted by temporary cleanup
procedures.

Marc André Tanner 277f4d154d Improve detection and handling of stale sessions 
With this it should be possible to create sessions for which a
dead left over socket still exists. Also the session list as
printed by abduco without any arguments will delete those stale
sockets.

Marc André Tanner 91b7338f9d Set socket creation permission in a portable way 
fchmod(2) on a socket file descriptor is unspecified behaviour
which happens to work on Linux. Use umask(2) instead which should
affect the permissions used by bind(2).

or explicitly requested via a command.

Marc André Tanner f7a3290c9c Recreate server socket upon receiving SIGUSR1 2014-03-06 17:19:10 +01:00
Marc André Tanner b205eeea9a Don't wait for clients to be present inorder to read program I/O 
Previously the underlying application would block on I/O because
we would wait to read it until a client is connected to display
the information. This prevented long running tasks from making
progress. However with the new approach output data of programs
which terminate while no client is connected is lost.

Marc André Tanner 12287e473d Accept resize request only from the client which connected first 
The problem this prevents is that when two instances are viewing
simultaneously they won't resize each other windows.

Marc André Tanner ed4f1ecdcd Use the same packet structure for both ways of the client server communiction 
This is slightly less efficient than before but allows the server
to send different types of messages not only output data to the
client.
