2022-03-15stricter error checking in file streams (input, output)Hiltjo Posthuma
This also makes the programs exit with a non-zero status when a read or write error occurs. This makes checking the exit status more reliable in scripts. A simple example to simulate a disk with no space left: curl -s 'https://codemadness.org/atom.xml' | sfeed > f /mnt/test: write failed, file system is full echo $? 0 Which now produces: curl -s 'https://codemadness.org/atom.xml' | sfeed > f /mnt/test: write failed, file system is full write error: <stdout> echo $? 1 Tested with a small mfs on OpenBSD, fstab entry: swap /mnt/test mfs rw,nodev,nosuid,-s=1M 0 0
2021-06-01portability and standards: add BSD-like err() and errx() functionsHiltjo Posthuma
These are BSD functions. - HaikuOS now compiles without having to use libbsd. - Tested on SerenityOS (for fun), which doesn't have these functions (yet). With a small change to support wcwidth() sfeed works on SerenityOS.
2020-11-01sfeed_xmlenc: be more paranoid in printing encoding namesHiltjo Posthuma
sfeed_xmlenc is used automatically in sfeed_update for detecting the encoding. In particular do not allow slashes anymore either. For example "//IGNORE" and "//TRANSLIT" which are normally allowed. Some iconv implementation might allow other funky names or even pathnames too, so disallow that. See also the notes about the "frommap" for the "-f" option. https://pubs.opengroup.org/onlinepubs/9699919799/utilities/iconv.html + some minor parsing handling improvements.

2019-07-20use the same XML handler names as the fields and shorten variable namesHiltjo Posthuma
Use the same XML handlers names as the fields to improve readability a bit. This is also consistent across all the programs using xml.c. Shorten the variable names aswell.
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++])
2018-12-02sfeed_xmlenc: don't treat not finding an encoding as an errorHiltjo Posthuma
in scripts empty output should be checked.
2018-12-02sfeed_xmlenc: simplify and don't print control charactersHiltjo 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.

2016-08-06add USE_PLEDGE, remove pledge dummy functionHiltjo Posthuma
2016-03-10remove cast of unused variablesHiltjo Posthuma
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.

2015-08-16code-style + no need to zero static variablesHiltjo Posthuma
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.

2015-01-02cleanupHiltjo Posthuma
- dont free at end (not needed in our case). - use 0 and 1 instead of EXIT_SUCCESS, EXIT_FAILURE. - use err (from err.h) instead of custom die().
