Drop PATH_MAX usage

2026-03-27T14:08:33Z

Strict POSIX systems (such as GNU Hurd) don't define PATH_MAX, which results in a build failure: https://buildd.debian.org/status/fetch.php?pkg=snac2&arch=hurd-amd64&ver=2.91-1&stamp=1774482136&raw=0 This commit replaces PATH_MAX with a dynamically-allocated buffer, which is the usual way of fixing these failures.

strip_exif support for the OpenBSD sandbox

2026-02-05T20:17:44Z

Change the strip_exif logic to work with the already existing OpenBSD sandbox and allow ffmpeg and mogrify to be executed. The previous strip_exif implementation relied on system(3), effectively starting "/bin/sh" and executing the required tool within a shell session. Making this work in the sandbox would require to allow executing "/bin/sh", rendering the sandbox useless. Thus, the code now starts determining the absolute path of the tools - unless they are given as ffmpeg_path or mogrify_path - and allowing them to be executed via unveil(2). Then, instead of the system(3) call, the good old fork(2) and execve(2) dance is performed. The sbox_enter code was made aware of strip_exif, which resulted in a pledge(2) violation before when disable_email_notifications was set to false. Furthermore, the detected paths of the tools are now allowed.

Added translatable month names.

Implement metadata stripping for uploaded videos

2026-01-06T11:18:00Z

- Extend `strip_media` to support video files using `ffmpeg`. - Use `ffmpeg -map_metadata -1 -c copy` to strip global metadata. - Support formats: mp4, m4v, mov, webm, mkv, avi. - Add `ffmpeg_path` configuration option. - Implement robust relative path handling (`user/` heuristic) to support jailed environments. - Enforce strict checks on startup: fail if tools (mogrify/ffmpeg) are missing when enabled.

Implement configurable EXIF stripping for uploaded media

2026-01-06T10:02:36Z

- Add `strip_exif` configuration option to enable metadata removal. - Add `mogrify_path` configuration to specify external tool location. - Implement strip_media using `mogrify -strip`. - Support multiple image formats: jpg, png, webp, heic, heif, avif, tiff, gif, bmp. - Add strict startup check: fail to start if `strip_exif` is enabled but `mogrify` is missing/broken. - Update documentation in `doc/snac.8`.
