xavi/libweb, branch master Small and lightweight web framework written in C99 and POSIX.1-2008. https://gitea.privatedns.org/xavi/libweb/atom?h=master 2026-02-27T15:29:06+00:00 Add http_strcasecmp(3) 2026-02-27T15:29:06+00:00 Xavier Del Campo Romero xavi92@disroot.org 2026-02-27T14:28:17+00:00 urn:sha1:6353beb60ceafbc743bde96684d666582195192f POSIX.1-2008 does not any locale-specific version of strcasecmp(3), so conversions to lowercase depend on the system locale. 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. Add http_strncasecmp(3) 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.

Replace Makefile with configure script 2026-02-13T06:54:07+00:00 Xavier Del Campo Romero xavi92@disroot.org 2026-02-12T16:58:06+00:00 urn:sha1:62ee3ef1ca13872e1f9b07f6e4e53cea8b684d72 Since libweb depends on dynstr, this dependency can be already available on the system, and therefore the CFLAGS and LDFLAGS should be updated according to pkg-config(1), rather than hardcoding them to the source tree. http.c: Remove unused variable 2026-02-12T16:59:49+00:00 Xavier Del Campo Romero xavi92@disroot.org 2026-02-12T16:59:36+00:00 urn:sha1:438fe10b069b355407cd42b244de5deb695f2338 http.c: Use expected timezone abbreviation 2026-02-12T16:26:54+00:00 Xavier Del Campo Romero xavi92@disroot.org 2026-02-12T16:26:54+00:00 urn:sha1:5f0cd92f0bdc74d1c087781dabc19b258bda0b2e The struct tm instance consumed by append_expire is provided by users and could refer to any timezone, rather than GMT only. According to Wikipedia [1], timezone abbreviations are either 3 or 4 characters long, or use numeric UTC offsets.

Otherwise, a failed call to strdup(3) would cause the caller to free h->elem at shutdown, but h->elem would still contain a dangling pointer, and therefore cause undefined behaviour. Add HTTP op and resource to length callback 2026-02-12T15:59:55+00:00 Xavier Del Campo Romero xavi92@disroot.org 2026-02-12T15:59:55+00:00 urn:sha1:87807c690947f4636dc4dd7fddca15f944719f0c Users might want to know which HTTP operation (i.e., POST or PUT) and/or resource is being requested before determining whether the request should be accepted or not. http.c: Force POSIX locale on append_expire 2026-02-12T15:11:45+00:00 Xavier Del Campo Romero xavi92@disroot.org 2026-02-12T15:11:45+00:00 urn:sha1:16f07314e675dd7d9d9cfb44dfb33cd81b13590d Otherwise, strftime(3) could return different strings depending on the system configuration, and therefore return 0 if the resulting string does not fit into buf.
