2019-04-20sfeed_frames, sfeed_html: do not send referer headerHiltjo Posthuma
Do not send referer header if the browser supports this tag. This makes sure in some browsers where referer hiding is not setup this header is still hidden. The proper way is to setup your browser environment however to strip/change the referer header and trim your browser footprint.
2019-04-06sfeed_frames/sfeed_html: improve HTML output a bitHiltjo Posthuma
declare UTF-8 before <title>
2018-08-21sfeed_frames: stricter pledge when only reading from stdinHiltjo Posthuma
2018-08-16sfeed_frames: overhaulHiltjo Posthuma
sfeed_frames used to write HTML pages for each entry for each feed. This can be useful but had security issues, because the context of the content changes. sfeed_frames is now a HTML version which works better with browsers that don't support CSS or tables well like w3m and lynx. It is now an alternative for sfeed_html. - Don't reference and embed HTML content for security reasons. This was documented under "SECURITY CONSIDERATIONS" in the man page. - Tighten pledge(2). - Simplify
2018-02-18sfeed_frames: code-styleHiltjo Posthuma
2017-12-24format programs: ignore fields with an invalid timeHiltjo Posthuma
this makes sure tail -f with multiple files ignores the ==> file <== lines too.
2017-08-12add newline after </html>Hiltjo Posthuma
2017-04-27simplify pledge stubHiltjo Posthuma
2017-04-27compatiblity with browsers: use numeric entity for aposHiltjo Posthuma
this entity is XHTML, it is not supported by some (older) browsers.
2016-08-06sfeed_frames, sfeed_html: don't use HTML tablesHiltjo Posthuma
reasons: - HTML table rendering is extremely slow (invalidate because of resizing cells etc). - whitespace wrapping does not work properly in ancient browsers, links(1).
2016-08-06add USE_PLEDGE, remove pledge dummy functionHiltjo Posthuma
2016-04-12sfeed_frames: make content filename more unique: use UNIX timestamp in titleHiltjo Posthuma
this makes sure if an item has the same title but is posted or updated at a different time it will not overwrite the file.
2016-04-10sfeed_frames: dont make title of content a link if its emptyHiltjo Posthuma
2016-04-10remove basename, just use last part of the path...Hiltjo Posthuma
... as a bonus it also saves an allocation.
2016-03-29add time parsing to sfeed itself, remove time fieldHiltjo Posthuma
- less overhead (we only need GMT time) so no setenv("TZ", ...) tzset() crap. - timezone format (for example %z in strptime) is non-standard, this will add some lines of code and some complexity to our code though, but the trade-off is worth it imho.
2016-03-20sfeed_frames: also XML encode formatted time (just in case)Hiltjo Posthuma
2016-03-04sfeed_frames: use S_IR* names (portability), respect umaskHiltjo Posthuma
use 0777 and 0666 permissions, it will respect the process umask (generally 0022), so 0755 and 0644 effectively.
2016-03-04sfeed_frames: use mkdir and check errno EEXISTHiltjo Posthuma
no need to stat and then mkdir, this is a (theoretical) race-condition too.
2016-02-29sfeed_frames: no need to read from index files, mode "w+b" to "wb"Hiltjo Posthuma
2016-02-29sfeed_frames: whoops, set file permissions (else its 0000)Hiltjo Posthuma
2016-02-28sfeed_frames: add fattr to pledge...Hiltjo Posthuma
... it did not abort, but set it anyway. I think cpath implies fattr, it makes sense.
2016-02-28sfeed_frames: fix open file permission (write only).Hiltjo Posthuma
check errno EEXIST (file exist? -> ignore), handle other errno codes as errors. ... also make sure to fflush write before modifying file access and modification timestamps or it will be overwritten again.
2016-02-28sfeed_frames: fix TOCTTUO with access() and fopen()Hiltjo Posthuma
... and use futimens() in favor of deprecated utime(). a minor difference in behaviour is now filetimes are only updated when the file doesn't exist. minor cleanup: remove namelen, its variable was unused (reported by cppcheck).
2016-02-28null-terminate line at newline from getline()Hiltjo 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.
2016-02-27remove some unneeded checksHiltjo Posthuma
2015-08-16code-style + no need to zero static variablesHiltjo Posthuma
2015-08-16code-style, wrap some lines, etcHiltjo Posthuma
2015-08-07util: strtotime: stricter time parsingHiltjo Posthuma
as input: an empty string or non-digit characters are digits are considered an error now. Still, for the format tools output the formatted time string as time_t 0 on a parse error.
2015-08-02sfeed_frames: wrap plain-text, encode as XML/HTML 2.0Hiltjo Posthuma
2015-08-02sfeed_frames: limit titles and feednames to 128 chars for filenamesHiltjo Posthuma
This prevents unnecessary path-truncation in some cases, with the side-effect it can overwrite items with the same title more often. We handle path truncation as a fatal error, so this was annoying.
2015-08-02sfeed_frames: normalizepath: dont start with replaced -, just ignoreHiltjo Posthuma
2015-08-02util: simplify parseline() and check t for strtotime().Hiltjo Posthuma
2015-08-02refactor print, decodefield into xmlencodeHiltjo Posthuma
... put specific formatting-logic per program (printcontent()).
2015-07-31Various improvementsHiltjo Posthuma
- Only escape characters in "content" field, these can contain newlines. - Trim newlines and tabs, etc from the title, id and author fields. - Make decodefield, xmlencode functions easier to "chain" without allocatting new buffers. - Move printutf8pad from util (only used by sfeed_plain) to sfeed_plain. - Update README, still need to update the man-page and improve the documentation in general. - Code cleanup.

2015-05-24sfeed_frames and util cleanupHiltjo Posthuma
- remove xerr and xerrx, assume the OS closes and flushes file descriptors on OS process exit. - move esnprintf, printcontent to util.
