A recurring problem, mainly on the BSD's, and also on some Linux
installations, is a failure for ttsession to start and any clients
trying to attach to it failing due to having a hostname that is not
associated with an IP address.
This is due to code which looks up the hostname, and if it does not
have a valid host record, then TT just fails.
This has required those users to add an alias for their host name in
their /etc/hosts file.
With this commit, this should no longer be necessary. Now, if
_XGethostbyname() fails when looking up the local name, a default of
"localhost" is used, which should always exist.
This was run tested on Linux and FreeBSD 11.1. It was compile tested
on OpenBSD 6.2.
This is enabled by default. To disable, add:
in the config/cf/site.def or host.def file.
You will need to have the libtirpc-dev package installed.
The benefit is that you will no longer need to run rpcbind in insecure
mode (the -i option). There are other benefits we may be able to take
advantage of in the future, like supporting IPV6 for ToolTalk.
This patch fixes many warnings from the beginning of the build up to
and including the depend stage. Nearly all warnings should be gone
even with -Wall.
__rpc_xdr is no longer available on FreeBSD 10.
(XDR is typedef'd as "struct XDR" and not "struct __rpc_xdr").
By the way, why did we ever need this? Probably
it should be removed. Leaving for __OpenBSD__ for now.
This code tried to automatically generate the X DISPLAY
from the combination of the hostname and display number;
however 127.0.0.1:0 is normally rejected by X11, so this
technique is no good. Fixes dticon hang on startup, caused by
XOpenDisplay failure leading to this message from tttrace:
tt_default_session_set(0x0x875190=="X 127.0.0.1 0") = 1032 (TT_ERR_ACCESS)
- Const strings referenced by non-const variables.
- Incorrect format specifers for printing addresses
- Unused variables
- Signed comparison to unsigned
Also fix an incorrect enumeration value in a switch statement.
This is a non-POSIX/ISO-C header. It is ok to include this on Linux, but it
is obsolete on BSD; FreeBSD even throws an error if you include it with
__STDC__ defined. Every system should nowadays have malloc() defined in
stdlib.h.
Diff is largely mechanical, replacing malloc.h with stdlib.h where it is not
yet included anyway.
In part of the tooltalk rpc code (mp_message.c), it was assumed that on
the majority of platforms, sizeof(uid_t)=sizeof(gid_t)=sizeof(long). On
Linux-x64, uid_t is an unsigned int, which makes the code fail: all
tooltalk messages fail to send with an RPC_CANTENCODEARGS at the
rpc-level, and TT_INTERNAL_ERR for the actual program. We instead
change the code to explicitly examine sizeof(uid_t) to see whether it is
int or long sized. This allows tooltalk-dependent functinoality
like logout and multiple calls to dtfile to work.
Enums may be represented with a smaller type than int; however, they are
automatically promoted to int when passed in va_arg lists, just as
short, char, etc. are. GCC thus "knows" that you never want to call
va_arg with an enum type, and instead inserts an abort.
Patch from Douglas Mencken <dougmencken@gmail.com>:
"%wc" is Microsoft extension, not supported in every Std C Library. So
if we don't want to print "%wc%wc%wc%wc%..." instead of real chars, we
shall not use it.
Before:
%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wcession[28326]:
_Tt_s_session::s_init(): 1051 (TT_ERR_INTERNAL)!
%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wcession[28326]: waitpid():
No child processes
%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wc%wcession[28326]: child
ttsession exited with status 1
After:
/usr/dt/bin/ttsession[12397]: _Tt_s_session::s_init(): 1051 (TT_ERR_INTERNAL)!
/usr/dt/bin/ttsession[12397]: waitpid(): No child processes
/usr/dt/bin/ttsession[12397]: child ttsession exited with status 1
Remove from individual Imakefiles.
Also, remove '#if 0' block in linux.cf, and remove empty
LinuxMachineDefines. This should be working correctly. If not, let me
know.
