The great integral types renaming.
The purpose of this is to rationalize the names used for various
integral types, so that they match their intended uses and follow
consist conventions, and eliminate types that were not semantically
different from each other.
The conventions are:
-- All integral types that measure quantities of anything are
signed. Some people disagree vociferously with this, but their
arguments are mostly theoretical, and are vastly outweighed by
the practical headaches of mixing signed and unsigned values,
and more importantly by the far increased likelihood of
inadvertent bugs: Because of the broken "viral" nature of
unsigned quantities in C (operations involving mixed
signed/unsigned are done unsigned, when exactly the opposite is
nearly always wanted), even a single error in declaring a
quantity unsigned that should be signed, or even the even more
subtle error of comparing signed and unsigned values and
forgetting the necessary cast, can be catastrophic, as
comparisons will yield wrong results. -Wsign-compare is turned
on specifically to catch this, but this tends to result in a
great number of warnings when mixing signed and unsigned, and
the casts are annoying. More has been written on this
elsewhere.
-- All such quantity types just mentioned boil down to EMACS_INT,
which is 32 bits on 32-bit machines and 64 bits on 64-bit
machines. This is guaranteed to be the same size as Lisp
objects of type `int', and (as far as I can tell) of size_t
(unsigned!) and ssize_t. The only type below that is not an
EMACS_INT is Hashcode, which is an unsigned value of the same
size as EMACS_INT.
-- Type names should be relatively short (no more than 10
characters or so), with the first letter capitalized and no
underscores if they can at all be avoided.
-- "count" == a zero-based measurement of some quantity. Includes
sizes, offsets, and indexes.
-- "bpos" == a one-based measurement of a position in a buffer.
"Charbpos" and "Bytebpos" count text in the buffer, rather than
bytes in memory; thus Bytebpos does not directly correspond to
the memory representation. Use "Membpos" for this.
-- "Char" refers to internal-format characters, not to the C type
"char", which is really a byte.
-- For the actual name changes, see the script below.
I ran the following script to do the conversion. (NOTE: This script
is idempotent. You can safely run it multiple times and it will
not screw up previous results -- in fact, it will do nothing if
nothing has changed. Thus, it can be run repeatedly as necessary
to handle patches coming in from old workspaces, or old branches.)
There are two tags, just before and just after the change:
`pre-integral-type-rename' and `post-integral-type-rename'. When
merging code from the main trunk into a branch, the best thing to
do is first merge up to `pre-integral-type-rename', then apply the
script and associated changes, then merge from
`post-integral-type-change' to the present. (Alternatively, just do
the merging in one operation; but you may then have a lot of
conflicts needing to be resolved by hand.)
Script `fixtypes.sh' follows:
----------------------------------- cut ------------------------------------
files="*.[ch] s/*.h m/*.h config.h.in ../configure.in Makefile.in.in ../lib-src/*.[ch] ../lwlib/*.[ch]"

----------------------------------- cut ------------------------------------
`fixtypes.sh' is a Bourne-shell script; it uses 'gr':
----------------------------------- cut ------------------------------------
#!/bin/sh
# Usage is like this:
# gr FROM TO FILES ...
# globally replace FROM with TO in FILES. FROM and TO are regular expressions.
# backup files are stored in the `backup' directory.
from="$1"
to="$2"
shift 2
echo ${1+"$@"} | xargs global-replace "s/$from/$to/g"
----------------------------------- cut ------------------------------------
`gr' in turn uses a Perl script to do its real work,
`global-replace', which follows:

Usage: $myName [--help] [--backup-dir=DIR] [--line-mode] [--hunk-mode]
PERLEXPR FILE ...
Globally modify a file, either line by line or in one big hunk.
Typical usage is like this:
[with GNU print, GNU xargs: guaranteed to handle spaces, quotes, etc.
in file names]
find . -name '*.[ch]' -print0 | xargs -0 $0 's/\bCONST\b/const/g'\n
[with non-GNU print, xargs]
find . -name '*.[ch]' -print | xargs $0 's/\bCONST\b/const/g'\n
The file is read in, either line by line (with --line-mode specified)
or in one big hunk (with --hunk-mode specified; it's the default), and
the Perl expression is then evalled with \$_ set to the line or hunk of
text, including the terminating newline if there is one. It should
destructively modify the value there, storing the changed result in \$_.
Files in which any modifications are made are backed up to the directory
specified using --backup-dir, or to `backup' by default. To disable this,
use --backup-dir= with no argument.
Hunk mode is the default because it is MUCH MUCH faster than line-by-line.
Use line-by-line only when it matters, e.g. you want to do a replacement
only once per line (the default without the `g' argument). Conversely,
when using hunk mode, *ALWAYS* use `g'; otherwise, you will only make one
replacement in the entire file!

In addition to those programs, I needed to fix up a few other
things, particularly relating to the duplicate definitions of
types, now that some types merged with others. Specifically:
1. in lisp.h, removed duplicate declarations of Bytecount. The
changed code should now look like this: (In each code snippet
below, the first and last lines are the same as the original, as
are all lines outside of those lines. That allows you to locate
the section to be replaced, and replace the stuff in that
section, verifying that there isn't anything new added that
would need to be kept.)
--------------------------------- snip -------------------------------------
/* Counts of bytes or chars */
typedef EMACS_INT Bytecount;
typedef EMACS_INT Charcount;
/* Counts of elements */
typedef EMACS_INT Elemcount;
/* Hash codes */
typedef unsigned long Hashcode;
/* ------------------------ dynamic arrays ------------------- */
--------------------------------- snip -------------------------------------
2. in lstream.h, removed duplicate declaration of Bytecount.
Rewrote the comment about this type. The changed code should
now look like this:
--------------------------------- snip -------------------------------------
#endif
/* The have been some arguments over the what the type should be that
specifies a count of bytes in a data block to be written out or read in,
using Lstream_read(), Lstream_write(), and related functions.
Originally it was long, which worked fine; Martin "corrected" these to
size_t and ssize_t on the grounds that this is theoretically cleaner and
is in keeping with the C standards. Unfortunately, this practice is
horribly error-prone due to design flaws in the way that mixed
signed/unsigned arithmetic happens. In fact, by doing this change,
Martin introduced a subtle but fatal error that caused the operation of
sending large mail messages to the SMTP server under Windows to fail.
By putting all values back to be signed, avoiding any signed/unsigned
mixing, the bug immediately went away. The type then in use was
Lstream_Data_Count, so that it be reverted cleanly if a vote came to
that. Now it is Bytecount.
Some earlier comments about why the type must be signed: This MUST BE
SIGNED, since it also is used in functions that return the number of
bytes actually read to or written from in an operation, and these
functions can return -1 to signal error.
Note that the standard Unix read() and write() functions define the
count going in as a size_t, which is UNSIGNED, and the count going
out as an ssize_t, which is SIGNED. This is a horrible design
flaw. Not only is it highly likely to lead to logic errors when a
-1 gets interpreted as a large positive number, but operations are
bound to fail in all sorts of horrible ways when a number in the
upper-half of the size_t range is passed in -- this number is
unrepresentable as an ssize_t, so code that checks to see how many
bytes are actually written (which is mandatory if you are dealing
with certain types of devices) will get completely screwed up.

typedef enum lstream_buffering
--------------------------------- snip -------------------------------------
3. in dumper.c, there are four places, all inside of switch()
statements, where XD_BYTECOUNT appears twice as a case tag. In
each case, the two case blocks contain identical code, and you
should *REMOVE THE SECOND* and leave the first.

I also work on GNU stuff for Unix on occasion. I'm familiar with SunOS (version 4.x.x), BSD (version 4.2 and up), Ultrix (version 4.2 and up). I've been porting GNU Emacs to VMS since spring 1991. This includes versions 18.57 to 18.59 and version 19.22. I maintain GNU vmslib. Programs supported: GNU vmslib: extending, installation, upgrading aid, simple and complex questions, you name it. GNU Emacs: porting, extending, installation, upgrading aid, customization, simple or complex questions, training, you name it. GNU autoconf: porting, extending, installation, upgrading aid. GNU zip, diffutils, m4, patch, texinfo: porting, installation, upgrading aid. GNU C/C++: installation, upgrading aid. I might start to hack at it some day. The list of programs I currently support represents both my interests and current priorities. Your interest and funding can influence my priorities. Experience: Fluent in C, C++, Emacs Lisp, Pascal as well as assembler on VAX, Motorola 680x0, Intel 8086 and 80x86. Modified key elements in Emacs (e.g., memory and process management) to work transparently on VMS. I have very good knowledge in the VMS operating system, as well as MS-DOS and IBM PC compatibles. I have worked for four and a half years as a VMS system manager. I've also provided consulting services on IBM PC compatibles, as well as held classes for IBM PC users. A reference list is available on request. Your Rate: $50-$80/hour (400-700 SEK in sweden), plus expenses. My rates are negotiable, depending on how interesting the project is to me.

Experience: I have B.A. and M.A. degrees in Computer Science and have completed all but the dissertation for a Ph.D. in C.S. My research for my Ph.D. is in the areas of logic, type systems, and programming language theory. My primary programming languages are Emacs Lisp, Perl, and Bourne shell, but of course I can program in any language. I have written numerous Emacs Lisp packages. I started the USENET "List of Frequently Asked Questions about GNU Emacs with Answers" and maintained it for more than two years. Most of my work has been related to the telephone system (modems, voice mail, etc.), but I am not limited to that. Send e-mail for my complete resume or curriculum vita. Programs supported: GNU Emacs and Taylor UUCP: Installation, training, customization, bug fixing, troubleshooting, extension, development, porting, or answering any kind of question. Any other GNU program: The same things, but I don't necessarily have huge amounts of experience with the particular program. Working conditions: I am usually available for part-time work (less than 20 hours per week including any travel time). I can sometimes make time for full-time work for a month or two; please inquire. I can either work in or near Boston or via the Internet or via telephone; travel outside the Boston metropolitan area can be negotiated. My schedule is very flexible. Any programs I write will normally have the copying conditions of the GNU General Public License; this is negotiable. Rates: $65/hour as an independent contractor. travel and telephone expenses. higher rates if extensive travel is required. Updated: 27Sep94. Herb Wood phone: 1-415-789-7173 email: <ru@ccnext.ucsf.edu> I'm a better "planner" than I am a hacker. A really good hacker will be able to keep many pieces of information in their short-term memory and to memorize new pieces of information at a fast rate. This is not my strong point. Rather, I excel in domains that require knowledge of the slightly more theoretical parts of computer science --for example, logic, formal methods of program development, and functional programming. I can write, and I have "tutoring" (teaching one-on-one) experience, an, unlike some programmers, I enjoy doing these things. I have spend a lot of time looking at the Emacs Lisp sources and customizing Emacs and VM. I think I can customize Emacs and its packages quickly and effectively.
