We can reduce our differences from upstream ksh by simply using their
ERROR_translate() function instead of our janky and obsolete msg_translate,
we also move DtGetMessage() to msgs.c and lockedfiledescriptors and,
unlockfiledescriptors to extra.c to lessen modifications to init.c, which
all changes will hopefully be moved elsewhere in the future
Remove a pile of old SGML stuff we no longer need in dtdocbook since
we use NSGMLS.
Use some TCL macros from m4/tcl.m4 to loacate and use information in
the tclConfig.sh script installed with TCL. I had to modify it to
export TCL_INCLUDE_SPEC, which was present but not imported.
This commit does three thing:
1. Sets appropriate bits on source files
2. Tells imake to build them as script files, not data files
3. Remove broken examples based on unused code
Upstream ksh has removed it's builtin aliases, favoring instead to make them
all builtin commands, this would also allow us to skip having to manually
merge another file, it was explained best in this email:
"Default aliases are an ugly hack that you are better off without.
Disadvantages include:
- 'unalias -a' becomes basically unusable as it gets rid of commands you
probably want;
- shell functions by those names are ignored (unless you quote their
names upon invocation);
- something like 'cmdname=foo; "$cmdname" bar baz' doesn't work if
$cmdname is an alias.
I strongly recommend removing the BLT_SPC flag from all of
your extra dtksh builtins. Making builtins "special builtins" is of no
real benefit at all, while introducing a pointless restriction: shell
functions by those names cannot be defined, which causes a risk of
incompatibility with scripts written for other shells. The BLT_SPC flag
is for a very few historic builtins that must have certain weird
corner-case behaviour of "special" builtins for POSIX compliance and
Bourne shell compatibility reasons."
So this is going to be tricky/painful getting this parser fully
operational. It's pretty hairy with various interdependencies and
generated code.
It's rather complicated how each sub dir depends on the previous one.
Also, the parser subdir has dependencies on the helptag subdir, and
vice-versa, so some hackery was needed to get that to work.
Due to the wierd interdepencencies between helptag and parser,
we disable parallel builds there.
This is some really horrible code and design - not surprising since it
dates to 1989.
I think it should just be removed -- who can maintain or refactor this
code?
Also, dthelp_htag1 is now built in pass1/parser/, not in
pass1/helptag/ as it used to be.
The localized/utils/merge utility used hardcoded temporary filenames
to do its thing. This prevented any Makefiles that called merge from
enabling parallel builds in order avoid the file collisions that would
result.
Now we:
- use filenames that embed the PID in them, making them unique
per-process
- place them in /tmp, rather than the current directory
As a result, we can now re-enable parallel builds for localized
app-defaults, config, and types.
The appmanager action files (/usr/dt/appconfig/appmanager/*) are now
created properly for the main 4 languages supported. As usual, the
en_US.UTF-8 locale is a symlink to C.
These files were previously created via the UDB database files via
imake. Obviously we aren't going to be using those in autotools.
So, each language now has an appmanager/ dir in
programs/localized/$LANG/ that will create them properly on a make and
make install. It uses a new appmgr.am template in localized/templates
to do this.
This also means all of these languages now can use the new actions
added by Antonis, even though they are not translated, they are at
least usable in those languages now.
Patch from Peter G.
Note, this is temporary - eventually we will want to use the system
nsgmls/onsgmls to handle this and remove our ancient copy of nsgmls.
Some of these functions were returning pointers cast as integers,
which of course is bad on a 64b LP64 systems.
This code should probably just be refactored at some point. There may
be other hidden issues, and all the casting just sucks.
