.SH X. Y2K Compliance in libpng
May 15, 2009
.SH X. Source code repository
Since about February 2009, version 1.2.34, libpng has been under "git" source
control. The git repository was built from old libpng-x.y.z.tar.gz files
going back to version 0.70. You can access the git repository (read only)
at
git://libpng.git.sourceforge.net/gitroot/libpng
or you can browse it via "gitweb" at
http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng
Patches can be sent to glennrp at users.sourceforge.net or to
png-mng-implement at lists.sourceforge.net or you can upload them to
the libpng bug tracker at
http://libpng.sourceforge.net
.SH XI. Coding style
Our coding style is similar to the "Allman" style, with curly
braces on separate lines:
if (condition)
{
action;
}
else if (another condition)
{
another action;
}
The braces can be omitted from simple one-line actions:
if (condition)
return (0);
We use 3-space indentation, except for continued statements which
are usually indented the same as the first line of the statement
plus four more spaces.
Comments appear with the leading "/*" at the same indentation as
the statement that follows the comment:
/* Single-line comment */
statement;
/* Multiple-line
* comment
*/
statement;
Very short comments can be placed at the end of the statement
to which they pertain:
statement; /* comment */
We don't use C++ style ("//") comments. We have, however,
used them in the past in some now-abandoned MMX assembler
code.
Functions and their curly brackets are not indented, and
exported functions are marked with PNGAPI:
/* This is a public function that is visible to
* application programers. It does thus-and-so.
*/
void PNGAPI
png_exported_function(png_ptr, png_info, foo)
{
body;
}
The prototypes for all exported functions appear in png.h.
We mark all non-exported functions with "/* PRIVATE */"":
void /* PRIVATE */
png_non_exported_function(png_ptr, png_info, foo)
{
body;
}
The prototypes for non-exported functions can appear in
pngpriv.h or in the file where the function is located.
The names of all exported functions and variables begin
with "png_", and all publicly visible C preprocessor
macros begin with "PNG_".
We put a space after each comma and after each semicolon
in "for" statments, and we put spaces before and after each
C binary operator and after "for" or "while". We don't
put a space between a typecast and the expression being
cast, nor do we put one between a function name and the
left parenthesis that follows it:
for (i = 2; i > 0; --i)
x[i] = a(x) + (int)b;
Other rules can be inferred by inspecting the libpng
source.
.SH XII. Y2K Compliance in libpng
May 16, 2009
Since the PNG Development group is an ad-hoc body, we can't make
an official declaration.
This is your unofficial assurance that libpng from version 0.71 and
upward through 1.4.0beta59 are Y2K compliant. It is my belief that earlier
upward through 1.4.0beta60 are Y2K compliant. It is my belief that earlier
versions were also Y2K compliant.
