sfeed_mbox: set the author as the display name for the From header again

2025-12-26T20:03:27Z

commit e2537f08dde958c02f835229ae11c5db785abd2a parent a16377b91f996a3cc9772c23cc8aadd48a13651c Author: Hiltjo Posthuma Date: Fri, 26 Dec 2025 21:03:27 +0100 sfeed_mbox: set the author as the display name for the From header again SFEED_MBOX_FROM now always overrides the header if it is set. Otherwise the default e-mail is , if there is an author name it is displayed. The name is quoted. For simplicity some characters like quotes, escape characters or text-encoding characters are removed, they are not handled at all (note that the author field cannot contain escape characters already, unless the user modified the parsed sfeed(5) format).

xml.c: more strictly check numeric entities from the "library" side

2025-12-11T19:21:38Z

commit a16377b91f996a3cc9772c23cc8aadd48a13651c parent 8cf6e3f18ddfaa0d71a3d0a5535a175502b1d276 Author: Hiltjo Posthuma Date: Thu, 11 Dec 2025 20:21:38 +0100 xml.c: more strictly check numeric entities from the "library" side For sfeed there is no functional difference, because of how entities are parsed in a certain way. The xml.{c,h} code is reusable and some programs might use xml_entitytostr() with less validation beforehand. These cases are now tested in the sfeed_tests repository also (98% to 100% coverage for xml.c).

sfeed: remove undefined behaviour of right shifting a negative value

2025-12-01T20:34:21Z

commit 6a6eb12cb0049eb6198b6dfc78aa5f54a742cf57 parent b9305cb278e35dc274264824143aa629dda9fe95 Author: Hiltjo Posthuma Date: Mon, 1 Dec 2025 21:34:21 +0100 sfeed: remove undefined behaviour of right shifting a negative value Found by cppcheck. This rewrites the bitshift hack in a more clear and defined behaviour. - improve comment for datetounix(): it does no validation of input ranges here and expects (pre-validated) valid input as if from struct tm fields. - micro-optimization, -68 is not needed. This is the same for "& 3" also.

minicurses.h: portability: Casting non-zero decimal integer literal to pointer

2025-11-13T12:45:37Z

commit 3e854e2a0d57f90bf6f7482cecb2741043ccaa6b parent 03b52640efbd9f8fdd2297740b1c79fa0a1a7652 Author: Hiltjo Posthuma Date: Thu, 13 Nov 2025 13:45:37 +0100 minicurses.h: portability: Casting non-zero decimal integer literal to pointer Fixes cppcheck warning. Checked against NetBSD curses and ncurses: ncurses has: libcurses/term.h:#define eat_newline_glitch CUR Booleans[4] NetBSD curses: #define t_eat_newline_glitch(t) (t)->flags[TICODE_xenl] libterminfo/term.h:#define eat_newline_glitch t_eat_newline_glitch(cur_term) where flags is of type: signed char *flags; So this type is different for minicurses, but should be fine for sfeed_curses.

sfeed_mbox: add mail headers and other improvements

commit 03b52640efbd9f8fdd2297740b1c79fa0a1a7652 parent 839a4563e809916ccdd8ebeac1461d8c7ffc62e7 Author: Hiltjo Posthuma Date: Tue, 11 Nov 2025 20:50:06 +0100 sfeed_mbox: add mail headers and other improvements Note: these changes may cause duplicate messages for existing users in some use-cases because the Message-ID, From and To header will be different. Changes: Add mail headers, they are now only set headers when they have a value and are non-empty. These headers are used by rss2email also: - X-RSS-ID: the item ID. - X-RSS-TAGS: the category tags, '|' in sfeed(5) is replaced by ','. - X-RSS-URL: the item link / URL. Also added: - X-RSS-Author: the item author. - X-RSS-Enclosure: the first enclosure. This allows more convenient filtering in many mail clients. One can further manipulate the headers using mail tools or awk or a sed expression for example. For example changing X-Feedname to X-Label etc. - Change the default From and To header. It does not use the system hostname or $USER anymore. Add environment variables with defaults: $SFEED_MBOX_FROM: $SFEED_MBOX_TO: - Fixes: The To header could contain characters that are invalid for the To header as well. - Fixes: The Message-ID field could contain spaces or invalid characters. Now it is "@newsfeed.local".

sfeed_update/sfeedrc example: use $basename variable name

sfeed_update: merge: change the default to use the last record

Most implementations using sort -u use a stable sort and use the first record found by the specified key (where the key are the fields: id, title, link). This means it kept the record found in the old file and not update the last content. Swap the default to use the last record instead of the first. An alternative in awk: merge() { LC_ALL=C awk -F '\t' '!x[$6 "\t" $2 "\t" $3]++' "$3" "$2" } Thanks Ivo Cicchese for the feedback!

Using the client timestamp is imprecise. - Do not use the modified timestamp of the ETag for If-Modified-Since this can differ as well. Probably too obvious to mention but this of course assumes the filesystem can be used to store the modification timestamp for the modified content. Based on feedback from free_electrician, thanks!

sfeed.c: optimize tag lookup by reverting the binary search to a linear lookup

It was changed to bsearch() in commit 3031d855807de20fc86cd3dd2375ce9473e86947 After some more testing: because the tags table is so small doing a linear scan over the table by first checking the length, and then (if needed) the tag name comparison is bit faster (6-11%), but of course depends on the input) in common cases than a binary search. In practise there is no noticable difference though. This simplifies the code a bit.

It can be used to more easily replace the logic of running feeds with xargs with something else like GNU/parallel. It can be used to reproduce the previous behaviour which didn't require xargs. See commit for the old logic: cdb8f7feb135adf6f18e389b4bbf47886089474a Example: feed() { # wait until ${maxjobs} are finished: will stall the queue if an item # is slow, but it is portable.

However since date ranges are not supported in RSS/Atom feeds anyway and do not make sense this separator can be supported without breaking anything. If an ISO8601 date range would be used it will still use the first parsed date.

sfeed_update/sfeed_opml_export: only allow regular files

It makes no sense to use device files or fifos with sfeed_update and it can cause issues, because sfeed_update expects to read the config file for each (child) invocation also.

POSIX defines it should support at least LINE_MAX (2048 typically). OpenIndiana xargs doesn't conform to POSIX. It doesn't use the largest constraint but errors out. From POSIX: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/xargs.html "Values of size up to at least {LINE_MAX} bytes shall be supported, provided that the constraints specified in the DESCRIPTION are met. It shall not be considered an error if a value larger than that supported by the implementation or exceeding the constraints specified in the DESCRIPTION is given; xargs shall use the largest value it supports within the constraints."

sfeed_update: use xargs -P -0

2023-12-26T14:59:39Z

commit cdb8f7feb135adf6f18e389b4bbf47886089474a parent 62bfed65ca91c34ea24b81b191c23d4542a7075b Author: Hiltjo Posthuma Date: Tue, 26 Dec 2023 15:59:39 +0100 sfeed_update: use xargs -P -0 Some of the options, like -P are as of writing (2023) non-POSIX: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/xargs.html. However many systems support this useful extension for many years now. Some historic context: The xargs -0 option was added on 1996-06-11, about a year after the NetBSD import (over 27 years ago at the time of writing): http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/xargs/xargs.c?rev=1.2&content-type=text/x-cvsweb-markup On OpenBSD the xargs -P option was added on 2003-12-06 by syncing the FreeBSD code: http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/xargs/xargs.c?rev=1.14&content-type=text/x-cvsweb-markup Looking at the imported git history log of GNU findutils (which has xargs), the very first commit already had the -0 and -P option on Sun Feb 4 20:35:16 1996 +0000. Tested on many systems, old and new, some notable: - OpenBSD 7.4 - Void Linux - FreeBSD 12 - NetBSD 9.3 - HaikuOS (uses GNU tools). - Slackware 11 - OpenBSD 3.8 - NetBSD 5.1 Some shells: - oksh - bash - dash - zsh During testing there are some incompatibilities found in parsing the fields so the arguments are passed as one argument which is split later on by the child program.

Reproduce: sfeed_update /dev/null; echo $?

Some changes and notes: - Change it so it is OK to set this value to 0 or negative (in the future). - sfeed_curses: truncating newmaxsecs to an int would limit the value too much. - Just use strtotime() and parse the value to time_t. This is a signed long (32-bit, until 2038) or signed long long (64-bit) on most platforms. - sfeed_curses gets the comparison time on reload aswell and it needs errno = 0, because it uses die(). time() is not guaranteed to set an errno if it fails. - Rename environment variable to $SFEED_NEW_AGE.
