System: perl version 3.0
Patch #: 20
Priority:
Subject: patch #19, continued
Description:
See patch #19.
Fix: From rn, say "| patch -p -N -d DIR", where DIR is your perl source
directory. Outside of rn, say "cd DIR; patch -p -N <thisarticle".
If you don't have the patch program, apply the following by hand,
or get patch (version 2.0, latest patchlevel).
After patching:
*** DO NOTHING--INSTALL ALL PATCHES UP THROUGH #27 FIRST ***
If patch indicates that patchlevel is the wrong version, you may need
to apply one or more previous patches, or the patch may already
have been applied. See the patchlevel.h file to find out what has or
has not been applied. In any event, don't continue with the patch.
If you are missing previous patches they can be obtained from me:

If you send a mail message of the following form it will greatly speed
processing:
Subject: Command
@SH mailpatch PATH perl 3.0 LIST
^ note the c
where PATH is a return path FROM ME TO YOU either in Internet notation,
or in bang notation from some well-known host, and LIST is the number
of one or more patches you need, separated by spaces, commas, and/or
hyphens. Saying 35- says everything from 35 to the end.
You can also get the patches via anonymous FTP from
jpl-devvax.jpl.nasa.gov (128.149.1.143).

+ Notes on the OS/2 Perl port
+
+ Raymond Chen
+ (rjc at math.princeton.edu)
+
+ -1. Background.
+
+ This port was based on the MS-DOS port by Diomidis Spinellis.
+
+ 0. Set-up.
+
+ First copy the files in the os2 directory into the parent
+ directory. Also install the file msdos/dir.h in your include
+ directory.
+
+ 1. Compiling.
+
+ Perl has been compiled under MS-DOS using the Microsoft C compiler
+ version 6.0. Before compiling install dir.h as <sys/dir.h>. You will
+ need a Unix-like make program and something like yacc (e.g. bison). I
+ just ran yacc on my UNIX box and downloaded the resulting y.tab.[ch]
+ files. Compilation takes 45 minutes on a 16MHz 386 machine running
+ no jobs other than the compiler, so you will probably need something to
+ do in the meantime. Like, say, lunch. (Compilation time does not
+ include formatting the manual.) If you compile with optimization
+ turned off, it takes about half as long.
+
+ The executable is 270k (perlsym.exe is 473k; if you compile
+ without optimization, the sizes are 329K/531K), and the top level
+ directory needs 800K for sources, 550K for object code, and 800K for the
+ executables, assuming you want to build both perl.exe and perlsym.exe
+ with full optimization.
+
+ The makefile will compile glob for you which you will need to place
+ somewhere in your path so that perl globbing will work correctly. All
+ the tests were run, although some modifications were necessary because
+ OS/2 isn't UNIX. The tests that failed failed because of limitations of
+ the operating system and aren't the fault of the compiler. a2p and s2p
+ were not tested.
+
+ In the eg directory you will find the syscalls.pl header file,
+ and a sample program that demonstrates some of the improvements
+ of the OS/2 version over the MS-DOS version and some of the
+ system calls.
+
+ 2. Using OS/2 Perl
+
+ The OS/2 version of perl has much of the functionality of the Unix
+ version. Here are some things that don't work: sockets, password
+ functions, [gs]et[eug]id, dbm functions, fork.
+
+ One thing that doesn't work is "split" with no arguments. Somehow,
+ yylval.arg is empty ... [[ Wait, sorry, I fixed that. --rjc ]]
+
+ Care has been taken to implement the rest, although the implementation
+ might not be the best possible. Here are short notes on the tricky
+ bits:
+
+ 2.1. In-place editing.
+
+ Files currently can be edited in-place provided you are creating a
+ backup. Considerable effort is made to ensure that a reasonable
+ name for the backup is selected, while still remaining within
+ the 8.3 contraints of the FAT filesystem. (HPFS users have nothing
+ to worry about, since HPFS doesn't have the stupid 8.3 rule.)
+
+ The rules for how OS/2 perl combines your filename with the suffix
+ (the thing passed to "-i") are rather complicated, but the basic
+ idea is that the "obvious" name is chosen.
+
+ Here are the rules:
+
+ Style 0: Append the suffix exactly as UNIX perl would do it.
+ If the filesystem likes it, use it. (HPFS will always
+ swallow it. FAT will rarely accept it.)
+
+ Style 1: If the suffix begins with a '.', change the file extension
+ to whatever you supplied. If the name matches the original
+ name, use the fallback method.
+
+ Style 2: If the suffix is a single character, not a '.', try to add the
+ suffix to the following places, using the first one that works.
+ [1] Append to extension.
+ [2] Append to filename,
+ [3] Replace end of extension,
+ [4] Replace end of filename.
+ If the name matches the original name, use the fallback method.
+
+ Style 3: Any other case: Ignore the suffix completely and use the
+ fallback method.
+
+ Fallback method: Change the extension to ".$$$". If that matches the
+ original name, then change the extension to ".~~~".
+
+ If filename is more than 1000 characters long, we die a horrible
+ death. Sorry.
+
+ Examples, assuming style 0 failed.
+
+ suffix = ".bak" (style 1)
+ foo.bar => foo.bak
+ foo.bak => foo.$$$ (fallback)
+ foo.$$$ => foo.~~~ (fallback)
+ makefile => makefile.bak
+
+ suffix = "~" (style 2)
+ foo.c => foo.c~
+ foo.c~ => foo.c~~
+ foo.c~~ => foo~.c~~
+ foo~.c~~ => foo~~.c~~
+ foo~~~~~.c~~ => foo~~~~~.$$$ (fallback)
+
+ foo.pas => foo~.pas
+ makefile => makefile.~
+ longname.fil => longname.fi~
+ longname.fi~ => longnam~.fi~
+ longnam~.fi~ => longnam~.$$$
+
+ 2.2. Directory access.
+
+ Are implemented, but in order to support telldir() and seekdir(),
+ they operate by reading in the entire directory at opendir(),
+ then handing out pieces of it each time you do a readdir().
+
+ 2.3. Pipes and redirection.
+
+ Pipes and redirection are supported. Although OS/2 does not
+ terminate programs which try to write to closed pipes, perl will
+ kill them for you if you do it like this:
+
+ open(I, "long-running-program|");
+ ... process a few lines ...
+ close(I); # discard the rest ...
+
+ The killing works like this: We wait until the child program either
+ closes its stdout or tries to write to it. If it writes to its stdout,
+ we kill it. Otherwise, we cwait for it. This is pretty much what UNIX
+ does by default.
+
+ All pipe commands are given to cmd.exe (or your COMSPEC) for execution as
+
+ CMD /c your-command-line
+
+ so you can go ahead and load it up with any goofy things you want,
+ like 2>1 redirection, more pipes, && || etc.
+
+ The pipe() function is also supported, so you can go ahead and
+ make your own funky file descriptor connections before piping off
+ a process. However, you have to mark the descriptor you are
+ retaining as NOINHERIT before spawning, else you are in deadlock city.
+ Unfortunately, there's no way to mark the handle as NOINHERIT yet.
+ It's on my wish list.
+
+ 2.4. Syscall and Ioctl
+
+ IOCtl is not supported because the API is very different from the
+ UNIX API. Instead, IOCtl is supported as a syscall. Here are
+ the syscalls I've written so far:
+
+ $OS2_GetVersion = 0;
+ $OS2_Shutdown = 1;
+ $OS2_Beep = 2;
+ $OS2_PhysicalDisk = 3;
+ $OS2_Config = 4;
+ $OS2_IOCtl = 5;
+ $OS2_QCurDisk = 6;
+ $OS2_SelectDisk = 7;
+ $OS2_SetMaxFH = 8;
+ $OS2_Sleep = 9;
+ $OS2_StartSession = 10;
+ $OS2_StopSession = 11;
+ $OS2_SelectSession = 12;
+
+ The arguments you pass are handed off to OS/2 without interpretation,
+ and the return value is returned straight to you. However, you don't
+ have to supply arguments for the ones whose descriptions are "must be
+ zero"; perl will supply the mandatory zeros for you.
+
+ 2.5. Binary file access
+
+ Files are opened in text mode by default. This means that CR LF pairs
+ are translated to LF. If binary access is needed the `binarymode'
+ function should be used. There is currently no way to reverse the
+ effect of the binary function. If that is needed close and reopen the
+ file.
+
+ 2.6. Priority
+
+ The getpriority and setpriority functions are implemented, but since
+ OS/2 priorities are different from UNIX priorities, the arguments aren't
+ the same. Basically, the arguments you pass are handed directly to
+ OS/2. The only exception is the last argument to setpriority. To make
+ it easier to make delta priorities, if the priority class is 0xff, it
+ is changed to 0. That way, you can write
+
+ setpriority(0,0,-2)
+
+ instead of
+
+ setpriority(0,0,0xfe)
+
+ to decrease the delta by 2.
+
+ 2.7. Interpreter startup.
+
+ The effect of the Unix #!/bin/perl interpreter startup can be obtained
+ under OS/2 by giving the script a .cmd extension and beginning the script
+ with the line
+
+ extproc C:\binp\perl.exe -S
+
+ You should provide the appropriate path to your executable, and
+ the -S option is necessary so that perl can find your script.
+
+ 2.8. The kill function.
+
+ UNIX and OS/2 have different ideas about the kill function. I've
+ done a pretty feeble job of taking perl's UNIXish approach and
+ trying to jam it into the OS/2 way. No doubt you'll find that
+ your kill()s aren't working. My apologies in advance.
+
+ 3. Bug reports.
+
+ I don't normally have access to an OS/2 machine, so if you find
+ a bug, you can go ahead and tell me about it, but the odds that
+ I'd be able to fix it are slim.
+
+ 4. Wish list.
+
+ 4.1. OS/2.
+
+ Make ENOPIPE a fatal error.
+
+ Permit linking of files. (Allegedly, they're working on this.)
+
+ Get a fork.
+
+ Make CMD.EXE pass through the return code of its child.
+
+ 4.2 perl.
+
+ Provide a nice way to add new functions to perl without having
+ to understand the innards of perl. Not being fluent in perl
+ innards hacking, I added my extra functions via syscall.
+
+ 4.3. My port.
+
+ 4.3.1. In-place editing.
+
+ Make more idiot-proof.
+
+ Allow in-place editing without backup. (How?)
+
+ 4.3.2. Spawning and piping.
+
+ Make popen() cleverer. Currently, it blindly hands everything
+ off to CMD.EXE. This wastes an exec if the command line didn't
+ have any shell metacharacters and if the program being run
+ is not a batch file.
+
+ Clever spawning is carried out by do_spawn. We should try
+ to make popen() do much of the same sort of preprocessing
+ as do_spawn does (which means, of course, that we probably
+ should yank out code to be dished off into a subroutine).
+
+ In do_spawn(), use DosExecPgm instead of spawnl in order to get more
+ precise reasons why the child terminated (RESULTCODES).

+ [Files currently can be edited in-place provided you are cre-

+ For example, don't do
