This makes the checksum number atleast 64-bit and makes the Message-ID header consistent across mixed 32-bit and 64-bit systems. Tested on amd64 and MIPS32BE.

2021-07-11sfeed.c: parsetime: support short digit years for RSS pubDate fields (RFC822)Hiltjo Posthuma
RSS (pubDate) uses RFC822 dates. This standard is obsoleted by RFC2822. The RSS 2.0 spec says for the pubDate field: "[...] All date-times in RSS conform to the Date and Time Specification of RFC 822, with the exception that the year may be expressed with two characters or four characters (four preferred)." RFC822 section 5.1 describes the syntax with 2 digit years: https://datatracker.ietf.org/doc/html/rfc822#section-5.1 It was obsoleted/fixed in RFC2822 section 4.3: https://datatracker.ietf.org/doc/html/rfc2822#section-4.3 " Where a two or three digit year occurs in a date, the year is to be interpreted as follows: If a two digit year is encountered whose value is between 00 and 49, the year is interpreted by adding 2000, ending up with a value between 2000 and 2049. If a two digit year is encountered with a value between 50 and 99, or any three digit year is encountered, the year is interpreted by adding 1900." In the real world I've seen all sites using RSS use the 4-digit format. For historic context of changes and what feeds it might affect: - RFC822 was published in 13 august 1982, obsoleted by RFC2822. - RFC2822 was published in april 2001, obsoleted by RFC5322. - RFC5322 was published in october 2008. - RDF was started around 1996. It was published around 2004. - March 15, 1999: RSS 0.90 (Netscape), published by Netscape and authored by Ramanathan Guha. - July 10, 1999: RSS 0.91 (Netscape), published by Netscape and authored by Dan Libby. - June 9, 2000: RSS 0.91 (UserLand), published by UserLand Software and authored by Dave Winer. - Dec. 25, 2000: RSS 0.92, UserLand. - Aug. 19, 2002: RSS 2.0, UserLand. - July 15, 2003: RSS 2.0 (version 2.0.1), published by the Berkman Center for Internet & Society at Harvard Law School and authored by Dave Winer. - July 15, 2003: RSS 2.0 (version 2.0.1-rv-1), published by the RSS Advisory Board. - July 17, 2003: RSS 2.0 (version 2.0.1-rv-2), RSS Advisory Board. - April 6, 2004: RSS 2.0 (version 2.0.1-rv-3), RSS Advisory Board. - May 31, 2004: RSS 2.0 (version 2.0.1-rv-4), RSS Advisory Board. - June 19, 2004: RSS 2.0 (version 2.0.1-rv-5), RSS Advisory Board. - January 25, 2005: RSS 2.0 (version 2.0.1-rv-6), RSS Advisory Board. - Aug. 12, 2006: RSS 2.0 (version 2.0.8), RSS Advisory Board. - June 5, 2007: RSS 2.0 (version 2.0.9), RSS Advisory Board. - Oct. 15, 2007: RSS 2.0 (version 2.0.10), RSS Advisory Board. - March 30, 2009 (current): RSS 2.0 (version 2.0.11), RSS Advisory Board.

2021-07-06sfeed_mbox: add option to print contentHiltjo Posthuma
- Add SFEED_MBOX_CONTENT environment option. When set to "1" it outputs the content aswell. This is disabled by default for security reasons, because many clients handle HTML in an insecure way. - Print link and enclosure on one line and align them.

This fixes a warning on Linux glibc: /usr/include/features.h:187:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp] 187 | # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" | ^~~~~~~ Tested on Void GNU/Linux glibc with gcc. Tested on various other platforms for regressions too namely: OpenBSD, NetBSD, FreeBSD, Void GNU/Linux musl.
2021-06-05README: fix escape sequence which is non-POSIXHiltjo Posthuma
The "\s" escape sequence is non-POSIX and GNU awk gives a warning: gawk: cmd. line:69: warning: escape sequence `\s' treated as plain `s' BSD awk does not give this warning and supports it. Use the POSIX [[:space:]] character class instead.
