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is obsolete on BSD; FreeBSD even throws an error if you include it with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 Pascal Stumpf <Pascal.Stumpf@cubes.de>:
So here are all the patches that deal with the fact that modern
compilers assume different scoping rules for variables declared in for
loops. On Linux, -fpermissive has been added as a compiler flag to
compensate for this old C code, but I think it is the wrong approach.
Sorry, couldn't help sneaking in a || defined(CSRG_BASED) and some casts
needed for other reasons ...
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
Added proper SharedDtSvcReqs in lnxLib.tmpl and CplusplusLibC in
linux.cf. This allows the libstdc++ dependancy to be properly
declared for libDtSvc so that it is not neccessary to hardcode 'CCLINK
= g++' in the Imakefiles of programs linking angainst libDtSvc.
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.
