I can also look to see if I can move the logic from +vms_crtl_init.c into it in a way that would sidestep that it has no +copyright notice at all.

He did say that +there are other options. + +This would clear the way for getting the similar code accepted into the +Bash and coreutils repositories. I have a report that the first bash +4.3 beta built on VMS and looked real good on the test run. + +I am currently working on adapting the packaging scripts from bash and +coreutils to gawk. Each product has had it unique features, so I have +not yet come up with a generic set of scripts. + +This is a preview what will be coming: + +backup_gawk_src.com - Builds a VMS equivalent to tar archive. By +placing the source in the PCSI kit, it covers the requirement of +providing source somewhere with the binary. + +build_gawk_pcsi_desc.com - Creates a VMS PCSI package manifest file. + +build_gawk_pcsi_text.com - text output by the VMS PCSI package installer. + +compare_gawk_source.com - I have the source checked out on an NFS +server. The backup program needs me to copy it to a VMS volume first. +This procedure makes sure that the two copies are the same and ready for +backup. + +gawk_alias_setup.com - Sets up gawk and awk links to gnv$gawk.exe. +Needed to repair when sins of the past partially break an install. + +gawk_verb.cld - for gawk to use gnv$gawk.exe as an image. Different +than gawk.cld. To properly add an image to the VMS command table, it +needs a prefix. I have "GNV$" registered as a prefix for this purpose. + +gnv_gawk_kit_name.com - Calculates the VMS PCSI package name, used for +both file names and file contents. + +gnv_gawk_startup.com - Run at VMS startup to make sure that the +environment is set up properly for gawk. + +pcsi_gawk_file_list.txt - Source file for build_gawk_pcsi_desc.com. + +remove_old_gawk.com - Needed to properly clean up sins of the past. +Only touches the the GNV provided gawk and awk programs. + +stage_gawk_install.com - Does a pre-install into a fake "root" directory +tree for the kitting procedure to pull files out of. + +Regards, +-John + +From wb8tyw@qsl.net Thu Dec 12 12:21:57 2013 +Return-Path: <wb8tyw@qsl.net> +Received: from skeeve.com (skeeve.com [127.0.0.1]) + by skeeve.com (8.14.4/8.14.4/Debian-2ubuntu2.1) with ESMTP id rBCAIn2l004322 + for <arnold@localhost>; Thu, 12 Dec 2013 12:21:55 +0200 +X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on + frenzy.freefriends.org +X-Spam-Level: +X-Spam-Status: No, score=-1.9 required=5.0 tests=BAYES_00,FREEMAIL_FROM + autolearn=ham version=3.3.1 +X-Envelope-From: wb8tyw@qsl.net +X-Envelope-To: <arnold@skeeve.com> +Received: from frenzy.freefriends.org [66.54.153.139] + by skeeve.com with IMAP (fetchmail-6.3.21) + for <arnold@localhost> (single-drop); Thu, 12 Dec 2013 12:21:55 +0200 (IST) +Received: from Encompasserve.org (Eisner.encompasserve.org [67.53.90.116]) + by freefriends.org (8.14.6/8.14.6) with ESMTP id rBC6FboY024650 + for <arnold@skeeve.com>; Wed, 11 Dec 2013 23:15:41 -0700 +Received: from [192.168.0.101] + (173-19-202-206.client.mchsi.com [173.19.202.206]) + by Encompasserve.org (PMDF V6.6 #13031) + with ESMTPSA id <01P1UDWPUU7M002J4J@Encompasserve.org> for arnold@skeeve.com; + Thu, 12 Dec 2013 00:15:35 -0600 (CST) +Date: Thu, 12 Dec 2013 00:15:38 -0600 +From: "John E.

MMK uses most unmodified MMS +description files and handles ODS-5 volumes better than MMS does. + +The optional POSIX subsystem is no longer supported on VMS. While I +used to know at what version this support stopped in my head, I have +forgotten, and so far have not found that with an online search. + +Most of the C runtime routines that formerly required the POSIX +subsystem are in the VMS C runtime, so there no separate POSIX builds +needed for newer versions of VMS. + +The behavior of the VMS C runtime is controlled by feature settings that +can be set by logical names before the program is run. + +These feature settings include the support of longer filenames with +almost any characters including UTF-8, on ODS-5 volumes and if routines +should behave in a more Unix like fashion. + +I will be adding vms_crtl_init.c to the next commit for vmsbuild.com and +descrip.mms. This vms_crtl_init.c detects when the program is running +under a bash or similar shell and sets the feature settings for better +UNIX compatibility, or sets them for better DCL compatibilities. +It makes sure that the extended filename support is enabled. +This way a single binary can be used for both the VMS environment and +the DCL environment. + +As a replacement, a GNV https://sourceforge.net/projects/gnv/ was +created. There is older version of gawk that is provided by that package. + +Recently a group of programmers have started trying to correct issues +with the GNV project and reorganize it as a collection of packages along +wth a VMSPORTS https://sourceforge.net/projects/vms-ports/ effort. + +The GNV environment provides a Bash shell and several other utilities +intended to simulate a Unix environment. + +The web page https://sourceforge.net/p/gnv/wiki/InstallingGNVPackages/ +documents what needs to be done before installing these newer packages +while GNV is in the transition phase. + +Currently only Bash 4.2.45 and Coreutils 8.21 have been packaged, both +are fixing critical issues in GNV. + +I plan to have a GAWK PCSI package that will be installed with the VMS +PRODUCT command. This package will install into the GNV directory +structure, which mimics a Linux directory tree, so I will need to +determine where to put the gawk.hlp file in it. + +Regards, +-John + + + +On 12/6/2013 7:20 PM, John E.

This is a common problem in older ports because + the exit() was not implemented correctly, and neither was + the rest of the C runtime. Day 1 porting bug that was inevitable. + + The first problem is that if I fix it to report the correct exit + status, it would break DCL procedures written to expect the + wrong value. + + The second problem is that the new exit() call does not + allow setting the severity values and the existing gawk code + is setting them for tests to use. + + Using reverse engineering, I have determined how to encode + the correct exit codes with severity into the old exit() + API. + + If the shell is a UNIX shell: + + * The input parameters and options are handled the same as Unix. + (I have forgotten if I sent you that patch yet) + + * The exit codes are correct. The DCL severity information + is also added even though most C programs will not use them. + +I do not know if would be permissible to change the behavior to always +use the correct exit code with the severity values set. + +Existing DCL code using the severity values would not notice this change. + +I would have to document how to convert UNIX exit codes to DCL values +for people to get the original codes back. + + + +In the documentation, I have been trying to change the case of the +filenames referenced in the VMS sections to be exact instead in upper case. + + +In general, on the older ODS-2 VMS file system, the files were stored +and displayed in upper case. + +In the newer ODS-5 file system, filenames are stored in a case preserved +state and are when unpacked from a repository are still in lower case. + +The VMS DCL shell also has an optional mode /PARSE=EXTEND mode where it +handles those names. + +In the normal mode DCL converts all unquoted parameters to upper case, +and then the C runtime converts all unquoted parameters to lower case. +A slight but significant difference. + +In the extended mode, DCL and the C runtime will also not do any +conversion of parameters. + +Which means that in extended mode, the target to the MMS or MMK program +needs to be in the exact case, or it may not be found. + +When you have an NFS mounted volume, like I do, things get a bit strange +on older VMS, like VAX/VMS, because it presents lower case filenames in +upper case, and uses the $ character to indicate when the case gets +inverted. + +Example: + +TOAD> dir src_root:[gawk.readme_d]readme.vms +%DIRECT-E-OPENIN, error opening SRC_ROOT:[GAWK.README_D]README.VMS;* as +input + +TOAD> dir src_root:[gawk.$readme_$d]$readme.vms + +Directory SRC_ROOT:[GAWK.$README_$D] + +$README.VMS;1 + +On current versions of VMS that support ODS-5, the exact case of the +files are seen. + +EAGLE> dir src_root:[gawk.readme_d]readme.vms + +Directory SRC_ROOT:[gawk.README_d] + +README.VMS;1 + +This affects build procedures as they must look for both path names. + +Regards, +-John + +--------------040502020402090508010905 +Content-Type: text/plain; charset=windows-1252; + name="gawktexti_in.gdiff" +Content-Transfer-Encoding: 7bit +Content-Disposition: attachment; + filename="gawktexti_in.gdiff" + +--- /src_root/gawk/doc/gawktexi.in Fri Dec 13 17:43:41 2013 ++++ /vms_root/gawk/doc/gawktexi.in Sun Dec 15 23:28:13 2013 +@@ -32713,6 +32713,9 @@ + @item + Prestandard VAX C compiler for VAX/VMS + ++@item ++GCC for VAX and Alpha has not been tested for a while. ++ + @end itemize + + @end itemize +@@ -33993,41 +33996,96 @@ + @appendixsubsubsec Compiling @command{gawk} on VMS + @cindex compiling @command{gawk} for VMS + +-To compile @command{gawk} under VMS, there is a @code{DCL} command procedure that +-issues all the necessary @code{CC} and @code{LINK} commands.

The backup program needs me to copy it to a VMS volume first. +This procedure makes sure that the two copies are the same and ready for +backup. + +gawk_alias_setup.com - Sets up gawk and awk links to gnv$gawk.exe. +Needed to repair when sins of the past partially break an install. + +gawk_verb.cld - for gawk to use gnv$gawk.exe as an image. Different +than gawk.cld. To properly add an image to the VMS command table, it +needs a prefix. I have "GNV$" registered as a prefix for this purpose. + +gnv_gawk_kit_name.com - Calculates the VMS PCSI package name, used for +both file names and file contents. + +gnv_gawk_startup.com - Run at VMS startup to make sure that the +environment is set up properly for gawk. + +pcsi_gawk_file_list.txt - Source file for build_gawk_pcsi_desc.com. + +remove_old_gawk.com - Needed to properly clean up sins of the past. +Only touches the the GNV provided gawk and awk programs. + +stage_gawk_install.com - Does a pre-install into a fake "root" directory +tree for the kitting procedure to pull files out of. + +Regards, +-John + |
