* Remove use of "%n" to appease de RaadtJune McEnroe2021-01-23
| | | | | | | | | | | | | Sure, it was completely unnecessary, but I resent being told how to use snprintf. https://cvsweb.openbsd.org/src/lib/libc/stdio/vfprintf.c?rev=1.79&content-type=text/x-cvsweb-markup Notes: My problem here is with yelling about a standard C feature that has legitimate uses, simply because it *could* be used in a way that might cause security issues. If you're going to do that, you may as well syslog(3) whenever someone runs any C code at all.
* Drop filesystem access iff possibleKlemens Nanni2021-01-23
| | | | | | | Log files and state save/restore both require read/write access to the filesystem, both during start and exit. If neither features are used, catgirl may run with "stdio tty".
* Drop exec capability iff restrictedKlemens Nanni2021-01-23
| | | | Nothing must be executed when running /copy, et al.
* Drop network capability after ircConnect()Klemens Nanni2021-01-23
| | | | | | catgirl has no reconnect feature and generally must not do anything but read/write from/to the connected socket which does not require "inet" or "dns" promises.
* Call pledge(2) after unveil(2)Klemens Nanni2021-01-23
| | | | | | Simplify logic, be more idiomatic and finalize by pledging after all unveiling is done by omitting the "unveil" promise and thereby not allowing further calls to it.
* Separate kiosk mode from restrict modeJune McEnroe2021-01-23
| | | | | | | | | | | Restrict mode will focus on sandboxing, while kiosk will continue to restrict IRC access through a public kiosk. Kiosk mode without restrict mode allows execution of man 1 catgirl with /help, assuming external sandboxing. The /list and /part commands are also added to the list of disabled commands in kiosk mode, since they are pointless without access to /join.
* Simplify windowUpdate loops and factor out windowTopJune McEnroe2021-01-21
| | | | | No idea why I made that more complicated than it had to be looping backwards.
* Document that M-l shows timestampsJune McEnroe2021-01-21
|
* Don't lose swapped window when navigating to current bufferJeremy O'Brien2021-01-19
|
* Use Warm heat for manually inserted blank linesJune McEnroe2021-01-19
| | | | Oops, forgot about these.
* Add example tmux(1) configKlemens Nanni2021-01-18
| | | | | Spawn one catgirl per network and handle reconnects through tmux, no extra tool required.
* Use Warm heat for blank lines 1.5June McEnroe2021-01-17
| | | | So they're not hidden by M-+.
* Add -I highlight option and /highlightJune McEnroe2021-01-16
|
* Rename ignore code to filterJune McEnroe2021-01-16
|
* Remove join/part/quit ignore exampleJune McEnroe2021-01-16
| | | | These can now be hidden with M-+.
* Save and load window visibility thresholdsJune McEnroe2021-01-16
|
* Restore toggling ignore with M--June McEnroe2021-01-16
| | | | So that pressing M-- repeatedly maintains the previous behavior.
* Generalize ignore toggling to visibility thresholdJune McEnroe2021-01-16
|
* Save and load the URL ring in the save file 1.4June McEnroe2021-01-11
|
* Don't pass nick to urlScan for MOTD and helpJune McEnroe2021-01-11
|
* Check fprintf return values rather than ferrorJune McEnroe2021-01-10
|
* Sandbox with unveil(2) on OpenBSD in restricted modeJune McEnroe2021-01-10
| | | | I wrote all this in vi and it was nice.
* Print chain to stdout with -oJune McEnroe2021-01-10
|
* Allow interspersing flags and config filesJune McEnroe2021-01-10
| | | | | | Don't wait for getopt_long to move all the arguments to the end. This allows overriding options set by config files by placing flags after them on the command line.
* Move -o to a separate SYNOPSIS lineJune McEnroe2021-01-10
|
* Exit immediately when using -oJune McEnroe2021-01-10
|
* Make SYNOPSIS arguments consistent with option namesJune McEnroe2021-01-09
| | | | Can't keep the 4-letter pattern forever :(
* Add -o and -t options to trust self-signed certificatesJune McEnroe2021-01-09
|
* Allow configuring the upper bound of the hash functionJune McEnroe2021-01-09
| | | | | | | This allows limiting the nick colors used to the 16-color terminal set without modifying the TERM environment variable. Produces different results from just using the default configuration in a 16-color terminal, but what can you do?
* Count width of 2 for invalid multibyte with high bitJune McEnroe2021-01-09
|
* Use execl rather than execlp for shellJune McEnroe2021-01-07
| | | | SHELL is an absolute path.
* Sandbox with pledge(2) on OpenBSDJune McEnroe2021-01-06
|
* Collapse whitespace while wrapping and discard trailing spaceJune McEnroe2021-01-04
| | | | | The latter avoids an extra blank line when a message ends with whitespace that hits the edge of the window.
* Split ignore fields to avoid over-eager * matchingJune McEnroe2021-01-01
| | | | | | | | | | Split ignore fields and match each separately to avoid an early * eagerly matching across several fields. For example, "* JOIN * *" should not match messages which happen to contain the word "JOIN" followed by two other words. Ignore capacity is reduced to 64 to keep the size of the array the same. I don't think it's an issue.
* Factor out reply count checking and decrementingJune McEnroe2020-12-30
|
* Add /whowasJune McEnroe2020-12-30
|
* Show setnames like nick changesJune McEnroe2020-12-30
|
* Add /setname commandJune McEnroe2020-12-29
| | | | | | I'm not sure about that replies check in handleStandardReply. If more of those are added the reply counter system will definitely need refactoring.
* Handle so-called Standard RepliesJune McEnroe2020-12-29
|
* Alphabetize STANDARDS sectionJune McEnroe2020-12-29
|
* Document commands which can be filteredJune McEnroe2020-12-08
|
* Clarify the optional portions of an ignoreJune McEnroe2020-12-08
| | | | | Each optional portion requires the optional portions before it, including a full hostmask.
* Fix manual page lintsJune McEnroe2020-12-08
|
* Clarify configuration file usage exampleJune McEnroe2020-12-08
| | | | Point to EXAMPLES and /help from the top of the manual.
* Handle 437 ERR_UNAVAILRESOURCE like ERR_NICKNAMEINUSEJune McEnroe2020-12-05
| | | | | Not totally clear under what conditions 437 is returned, but if it happens during registration, we should pick a new nick.
* Split /exec lines by \r as well as \nJune McEnroe2020-11-24
| | | | | This fixes local rendering of /exec toilet --irc, which outputs \r\n line endings.
* Add topic diffing to notable features 1.3June McEnroe2020-11-11
|
* Use wmemcpy/wmemmoveJune McEnroe2020-11-08
|
* Remove static buffer from colorMentionsJune McEnroe2020-11-08
