2020-10-31sfeed_web: improve parsing a <link> if it has no type attributeHiltjo Posthuma
This happens because the previous link type is not reset when a <link> tag starts again, but it is reset when a type attribute starts. Found on the spanish newspaper site: elpais.com Input: <link rel="alternate" href="https://feeds.elpais.com/mrss-s/pages/ep/site/elpais.com/portada" type="application/rss+xml" title="RSS de la portada de El País"/> <link rel="canonical" href="https://elpais.com"/> Would print (second line is incorrect). https://feeds.elpais.com/mrss-s/pages/ep/site/elpais.com/portada application/rss+xml https://elpais.com/ application/rss+xml Now prints: https://feeds.elpais.com/mrss-s/pages/ep/site/elpais.com/portada application/rss+xml Fix: reset it also at the start of a <link> tag in this case (for <base href /> it is still not wanted).

2020-10-22sfeed_web: attribute parsing improvements, improve man pageHiltjo Posthuma
Fix attribute parsing and now decode entities. The following now works (from helsinkitimes.fi): <base href="https://www.helsinkitimes.fi/" /> <link href="/?format=feed&amp;type=rss" rel="alternate" type="application/rss+xml" title="RSS 2.0" /> <link href="/?format=feed&amp;type=atom" rel="alternate" type="application/atom+xml" title="Atom 1.0" /> Properly associate attributes with the actual tag, this now parses properly (from ascii.jp). <link rel="apple-touch-icon-precomposed" href="/img/apple-touch-icon.png" /> <link rel="alternate" type="application/rss+xml" />
2020-10-21sfeed_web: reset feedlink bufferHiltjo Posthuma
Noticed strange output on the site ascii.jp: The site HTML contained: <link rel="apple-touch-icon-precomposed" href="/img/apple-touch-icon.png" /> <link rel="alternate" type="application/rss+xml" /> This would print: "/img/apple-touch-icon.png application/rss+xml" Now it prints: " application/rss+xml"
2020-03-11sfeed_web: fix exit status codeHiltjo Posthuma
- Fix a theoretical issue where "found" can overflow and return a zero exit status when there are many feeds found. - When there are no RSS/Atom feeds this is not an error, so return 0. - Style: change unsigned int to int.

2020-01-18sfeed_web: remove unneeded optimizationHiltjo Posthuma
2019-04-06optimization: define GETNEXT as an inline macroHiltjo Posthuma
This reduces much function call overhead. getnext is defined in xml.h for inline optimization. sfeed only uses one XML parser context per program, this allows further optimizations of the compiler also. On OpenBSD it was noticable because of retpoline etc function call overhead. Using clang and a 500MB test XML file reduces processing time from +- 12s to 5s. Tested using some crazy optimization flags: SFEED_CFLAGS = -O3 -std=c99 -DGETNEXT=getchar_unlocked -fno-ret-protector \ -mno-retpoline -static A GETNEXT macro is also nice for programs which mmap(2) some big XML file. Then you can simply define: #define GETNEXT() (off >= len ? EOF : reg[off++])
2019-02-08short some callback variable names, change "name" to "t" (tag)Hiltjo Posthuma
2018-11-09minor white-space style fixHiltjo Posthuma
2018-09-07fix many undefined behaviour in usage of ctype functionsHiltjo Posthuma
- cast all ctype(3) function argument to (unsigned char) to avoid UB POSIX says: "The c argument is an int, the value of which the application shall ensure is a character representable as an unsigned char or equal to the value of the macro EOF. If the argument has any other value, the behavior is undefined." Many libc cast implicitly the value, but NetBSD does not, which is probably the correct thing to interpret it. - no need to cast for putchar + rename some fputc(..., stdout) to putchar POSIX says: "The fputc() function shall write the byte specified by c (converted to an unsigned char) to the output stream pointed to by stream [...]" Major thanks to Leonardo Taccari <iamleot@gmail.com> for reporting and testing it on NetBSD!
2018-08-22remove stdint.h includeHiltjo Posthuma
the uint* types in XML are not exposed anymore.
2018-03-11include <sys/types.h> for types size_t, ssize_t etcHiltjo Posthuma
This makes sure xml.c in particular can be compiled without further feature macros.

2016-02-27various improvementsHiltjo Posthuma
- pledge tools and add define to enable it on platforms that support it, currently only OpenBSD 5.9+ - separate getline and parseline functionality. - use murmur3 hash instead of jenkins1: faster and less collisions. - make some error messages a bit more clear, for example with path truncation. - some small cleanups, move printutf8pad to util.

2015-08-14xml: separate reader context from parserHiltjo Posthuma
also: - rename xmlparser_ prefix to xml_. - make xml_parse public, this allows a custom reader like a direct mmap, see: XMLParser.getnext and (optionall) XMLParser.getnext_data. - improve the README text.
