This was removed before, because of potential security issues in commit
b7e288a96418e1ea5e7904ab2896edb3f4615a10
Thanks trqx for the feedback.

this also makes packaging slightly simpler.

Man pages:
- sfeed_update: fix: fetchfeed parameter documentation.
- sfeed_update: fix/update: urls in sfeedrc.example.
- sfeed_update: document maxjobs variable.
- sfeedrc: document filter and order functions here.
- more semantic keywords: function arguments and some Nm.
README:
- Document more clearly sfeedrc is a shellscript at the first usage "steps".
- Add newsboat OPML export and import to sfeed_update example.
- Document the Makefile is POSIX (not some GNU/Makefile).
- Add reference to my tool hurl: a HTTP/HTTPS/Gopher file grab client.
- Describe the reason/usefulness of the filter example.
- Describe how to override curl(1), an optional dependency.
With feedback from lich, thanks!

- reduce amount of data to check.
- remove unnecesary checks from (now) internal functions.
|
|
|
|
|
|
+ change "append" to "change".
|
|
The files are now checked every 10 seconds instead of 1 second.
NOTE: ofcourse it still first checks the filesize and modification time and
only then proceeds.
|
|
in scripts empty output should be checked.
|
|
|
|
- Stricter parsing of tags, no whitespace stripping after <.
- For end tags the "internal" context x->tag would be "/sometag". Make sure
this matches exactly with the parameter tag.
- Reset tagname after parsing an end tag.
- Make end tag handling more consistent.
- Remove temporary variable taglen.

This reverts commit 8699fa2bb4c75670952fee503a58ca4a652627eb.
There is a regression in directory permissions among other things.
|
|
+ fix wrong comment "temporary file" -> "temporary directory".
|
|
|
|
|
|
|
|
- reorder and remove a goto.
- no need for a separate variable "end".
- don't use s[0] style because the pointer was changed.
|
|
- Handle SIGTERM properly, don't leave stray processes. Kill them on both
SIGTERM and SIGINT.
- When a "batch" of feeds was interrupted, don't allow to wait again.
- Simplify and create sighandler function.
- Now on both SIGTERM and SIGINT the cleanup() handler is called to not leave
stray files.
Tested with ksh, dash, bash, zsh.
|
|
When SIGINT occurs on waiting for jobs it returns 130 (128 + SIGINT). Make sure
to check for interrupted and return immediately.
Tested with ksh, dash, bash, zsh.
Sidenote: ideally we want to cleanup() on SIGTERM too, but this is too
inconsistent over various shells.

noticed in "RMS notes" RSS.

This adds a variable for the maximum amount of feeds to update concurrently. A
system/user may have fork resource limits or want to setup some job limit.
Thanks leot for the idea and feedback!

Pass the name parameter to the functions and add these to the pipeline. They
can be overridden in the config.
- add the ability to change the merge logic per feed.
- add the ability to filter lines and fields per feed.
- add the ability to order lines differently per feed.
- add filter example to README.
- code-style:
- fetchfeed consistency in parameter order.
- change [ x"" = x"" ] to [ "" = "" ]. Simplify some if statements.
- wrap long line in fetchfeed().
- use signal names for trap.
|
|
|
|
... this is useful to change the interrupted behaviour in some use-cases.
Thanks leot for the feedback.

Reported by "Dekedro", thanks!

- 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!

long is atleast 32-bits, codepointtoutf8() works with >= 32-bit types. Valid
codepoint ranges are not larger than this. unsigned char is not needed because
converted unicode bytes don't use this range.
tested all valid codepoints and output on amd64, i386 and SPARC64.

- don't output content and HTML mail anymore: this is very insecure for most
mail clients.
- improve Content-Type utf-8 encoding header (use the more common form).
- improve line-endings at the end of the data.
