see RFC2822 4.3 page 32: " [...] However, because of the error in [RFC822], they SHOULD all be considered equivalent to "-0000" unless there is out-of-band information confirming their meaning. "

2019-05-08README: add tail-like example in honor of the removed sfeed_tailHiltjo Posthuma
2019-05-06remove sfeed_tail and recently added security considerationsHiltjo Posthuma
... both are out-of-scope for sfeed. - sfeed_tail can be written as some simple customized awk script reading from a FIFO. The C version did not work well on FIFO's. - Security considerations are mentioned in the official HTML spec and applies to all HTML and protocol handlers, so is out-of-scope.
2019-05-03bump version to 0.9.10Hiltjo Posthuma

2019-05-02sfeed_update: disable If-Modified-Since by defaultHiltjo Posthuma
2019-05-02sfeed: improve content type (attribute) handlingHiltjo Posthuma
- handle type attribute for MRSS media:description, media:description type="plain" is now parsed properly. - handle default content-types per tag now. - when multiple content-like fields are specified use the proper content-type. - be flexible about type attribute handling. - minor code tweaks.
2019-05-02sfeed.{1,5}: reword "saved" to outputHiltjo Posthuma
this program does not store anything, but just write to stdout.
2019-05-02README: add security considerations, tweak preface a bitHiltjo Posthuma
2019-04-30improve READMEHiltjo Posthuma
- add preface text. - use "\t" pattern for awk (easier to read and copy-paste). - add a small example to get the most recent enclosure.
2019-04-30sfeed_frames, sfeed_html: use the same code for link handlingHiltjo Posthuma
2019-04-30sfeed_gph: when a link is empty show as regular textHiltjo Posthuma

2019-04-25sfeed_mbox: use simpler djb2 hash, fix message-id as intendedHiltjo Posthuma
The message-id has not been working as intended for a while. It only hashed the timestamp field because parseline() modifies the buffer in-place.

2019-04-20add sfeed_atom: convert one or more feeds from TSV (back to) AtomHiltjo Posthuma
2019-04-20README: update filter exampleHiltjo Posthuma
- Show how to filter protocol schemes more strictly. For example to allow only http://, https:// and gopher:// (not file://, javascript:, etc). - Filter links and now also enclosures.
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.
2019-04-15util: remove unneeded err.h headerHiltjo Posthuma

2019-04-14sfeed_update: rename fetchfeed to fetchHiltjo Posthuma
... and simplify example in README.
2019-04-14sfeed_tail: rename "line" to "l" in local scopeHiltjo Posthuma
char *line is a global variable (reused pointer to line buffer).
2019-04-14sfeed: add support for the first enclosure of an itemHiltjo Posthuma
This is useful for example for podcasts (audio attachment), newsposts (usually some image) or comic strips (link to page, image as enclosure). thanks leot for the feedback!
2019-04-14sfeed_update improvementsHiltjo Posthuma
- Better checking and verbose logging (on failure) of each stage: fetchfeed, filter, merge, order, convertencoding. This makes sure on out-of-memory, disk-space or other resource limits the output is not corrupted. - This also has the added advantage it runs less processes (piped) at the same time. - Clear previous unneeded file to preserve space in /tmp (/tmp is often mounted as mfs/tmpfs). - Add logging function (able to override), use more logical logging format (pun intended). - Code-style: order overridable functions in execution order.
2019-04-07README: change procmail parallel running, improve some wordsHiltjo Posthuma
make the procmail example safer due to account process limits.

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++])
2019-04-06sfeed_frames/sfeed_html: improve HTML output a bitHiltjo Posthuma

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).
2019-03-08util: pedantic snprintf improvementHiltjo Posthuma
POSIX says about snprintf: "If an output error was encountered, these functions shall return a negative value". So check for < 0 instead of -1. Afaik all implementations return -1 though.

2019-03-03sfeed: style, break in switch instead of returnHiltjo Posthuma
this style change is useful for my local coverage profile.

2019-02-27improve RSS2 permalink supportHiltjo Posthuma
In RSS2 (but not RSS0.9), a <link> is optional and it can also be specified by <guid isPermaLink="true"> (permalink is "true" by default). When a <link> is also present this will be used instead of the GUID permalink.
