2021-04-28enable unlocked I/O by defaultHiltjo Posthuma
getchar_unlocked is part of POSIX and should be supported by most platforms. On all tested platforms it has a performance benefit, sometimes smallish (<12%), sometimes large (~40%).
2020-10-09xml: remove unused code for sfeedHiltjo Posthuma
2020-10-09xml.h: minor comment rewordingHiltjo Posthuma
2020-10-09xml.c: remove buffering of comment data, which is unused anywayHiltjo Posthuma
2020-10-09xml.h: add underscore for #ifdef guardHiltjo Posthuma
This is the common style.

2019-09-12xml.h: remove #if 0 blockHiltjo 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++])
2019-03-16xml: write x->getnext to a default GETNEXT macroHiltjo Posthuma
this allows to override x->getnext to expand to global context parsing and allows the compiler to optimize this inline. also remove checking if the x->getnext function exists (just crash hard).
2018-08-21xml: interface change: make some functions privateHiltjo Posthuma
... this does not expose the uint* types either.
2018-08-21xml: increase allowed size of attribute namesHiltjo Posthuma

2015-08-22xml: simplify XML readerHiltjo Posthuma
2015-08-16xml: change xml_parse_string to xml_parse_bufHiltjo Posthuma
In the parser itself allow reading '\0' in the XML itself. Add a length parameter to specify the buffer size.
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.
