Small and lightweight web framework written in C99 and POSIX.1-2008. https://gitea.privatedns.org/xavi/libweb/atom?h=v0.6.0 2026-09-27T20:11:04+00:00 2026-09-27T20:11:04+00:00 Xavier Del Campo Romero xavi92@disroot.org 2026-09-27T20:11:04+00:00 urn:sha1:284551675d7596c6de9edbf488701395823e1d3c Whereas libweb does support returning partial transfers [1], it only does so limited to file transfers because it can be difficult or impossible to perform a partial request for what can be otherwise dynamically generated content. Previously, libweb naively accepted any range request from the client and silently replaced the response status to "206 Partial Content". [2] However, if no FILE * had been specified by the application, adjust_partial would treat this as a fatal error, because libweb assumed this as a programming error by the application.

Since HTTP header fields must be checked without case sensitivity and not depend on the system locale, a specialised function that forces the "POSIX" locale is required. 2026-02-27T15:28:52+00:00 Xavier Del Campo Romero xavi92@disroot.org 2026-02-27T11:30:45+00:00 urn:sha1:d783e794c2fa6a9e6bffff9f41cdb7e8033bf3c3 POSIX.1-2008 does not any locale-specific version of strncasecmp(3), so conversions to lowercase depend on the system locale.

According to Wikipedia [1], timezone abbreviations are either 3 or 4 characters long, or use numeric UTC offsets.

While good enough for some contexts, libweb should allow users to set up their own, if any, so this arbitary decision has been eventually removed.
