Y2K compliance in libpng:
|
||||
=========================
|
||||
|
||||
January 13, 1999
|
||||
|
||||
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 0.81 and
|
||||
upward are Y2K compliant. It is my belief that earlier versions were
|
||||
also Y2K compliant.
|
||||
|
||||
Libpng only has three year fields. One is a 2-byte unsigned integer
|
||||
that will hold years up to 65535. The other two hold the date in text
|
||||
format, and will hold years up to 9999.
|
||||
|
||||
The integer is
|
||||
"png_uint_16 year" in png_time_struct.
|
||||
|
||||
The strings are
|
||||
"png_charp time_buffer" in png_struct and
|
||||
"near_time_buffer", which is a local character string in png.c.
|
||||
|
||||
There are seven time-related functions:
|
||||
|
||||
png_convert_to_rfc_1123() in png.c
|
||||
(formerly png_convert_to_rfc_1152() in error)
|
||||
png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
|
||||
png_convert_from_time_t() in pngwrite.c
|
||||
png_get_tIME() in pngget.c
|
||||
png_handle_tIME() in pngrutil.c, called in pngread.c
|
||||
png_set_tIME() in pngset.c
|
||||
png_write_tIME() in pngwutil.c, called in pngwrite.c
|
||||
|
||||
All appear to handle dates properly in a Y2K environment. The
|
||||
png_convert_from_time_t() function calls gmtime() to convert from system
|
||||
clock time, which returns (year - 1900), which we properly convert to
|
||||
the full 4-digit year. There is a possibility that applications using
|
||||
libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
|
||||
function, or incorrectly passing only a 2-digit year instead of
|
||||
"year - 1900" into the png_convert_from_struct_tm() function, but this
|
||||
is not under our control. The libpng documentation has always stated
|
||||
that it works with 4-digit years, and the APIs have been documented as
|
||||
such.
|
||||
|
||||
The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
|
||||
integer to hold the year, and can hold years as large as 65535.

|
||||
* Y2K compliance in libpng:
|
||||
* =========================
|
||||
*
|
||||
* January 13, 1999
|
||||
*
|
||||
* 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 0.81 and
|
||||
* upward are Y2K compliant. It is my belief that earlier versions were
|
||||
* also Y2K compliant.
|
||||
*
|
||||
* Libpng only has three year fields. One is a 2-byte unsigned integer
|
||||
* that will hold years up to 65535. The other two hold the date in text
|
||||
* format, and will hold years up to 9999.
|
||||
*
|
||||
* The integer is
|
||||
* "png_uint_16 year" in png_time_struct.
|
||||
*
|
||||
* The strings are
|
||||
* "png_charp time_buffer" in png_struct and
|
||||
* "near_time_buffer", which is a local character string in png.c.
|
||||
*
|
||||
* There are seven time-related functions:
|
||||
* png.c: png_convert_to_rfc_1123() in png.c
|
||||
* (formerly png_convert_to_rfc_1152() in error)
|
||||
* png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
|
||||
* png_convert_from_time_t() in pngwrite.c
|
||||
* png_get_tIME() in pngget.c
|
||||
* png_handle_tIME() in pngrutil.c, called in pngread.c
|
||||
* png_set_tIME() in pngset.c
|
||||
* png_write_tIME() in pngwutil.c, called in pngwrite.c
|
||||
*
|
||||
* All handle dates properly in a Y2K environment. The
|
||||
* png_convert_from_time_t() function calls gmtime() to convert from system
|
||||
* clock time, which returns (year - 1900), which we properly convert to
|
||||
* the full 4-digit year. There is a possibility that applications using
|
||||
* libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
|
||||
* function, or incorrectly passing only a 2-digit year instead of
|
||||
* "year - 1900" into the png_convert_from_struct_tm() function, but this
|
||||
* is not under our control. The libpng documentation has always stated
|
||||
* that it works with 4-digit years, and the APIs have been documented as
|
||||
* such.
|
||||
*
|
||||
* The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
|
||||
* integer to hold the year, and can hold years as large as 65535.

|

*
|

|

* Due to various miscommunications, unforeseen code incompatibilities
|
||||
* and occasional factors outside the authors' control, version numbering
|
||||
* on the library has not always been consistent and straightforward.
