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 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. 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.

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. 2025-10-07T23:57:42+00:00 Xavier Del Campo Romero xavi92@disroot.org 2025-10-06T21:01:42+00:00 urn:sha1:e77bd93693a74ce872d4c13fb45537c34518d84f A new function pointer, namely chunk, has been added to struct http_response so that library users can generate their message bodies dynamically. 2025-10-06T19:03:59+00:00 Xavier Del Campo Romero xavi92@disroot.org 2025-10-06T19:03:59+00:00 urn:sha1:db9cb051c4ee05c07ab32dfed5bae8b7dc0916bd libweb calls listen(2) when setting up the HTTP server, and its backlog argument was hardcoded to 10. While probably not an issue for some applications, it can be too limiting for some others. Therefore, it is desirable to allow library users to set up their own limits. Otherwise, 10 is still chosen as a sane default. 2025-10-06T13:51:00+00:00 Xavier Del Campo Romero xavi92@disroot.org 2025-10-05T23:23:20+00:00 urn:sha1:3e4c7c993bbbe2bdeb563fa888b900d01c4be4a1 struct http_response did not provide users any void * that could be used to maintain a state between calls to an asynchronous HTTP response. On the other hand, the user pointer could not be used for this purpose, since it is shared among all HTTP clients for a given struct handler instance. Moreover, the length callback was still not supporting this feature, which in fact might be required by some users. Implementing this was particularly challenging, as this broke the current assumption that all bytes on a call to http_read were being processed. Now, since a client request can only be partially processed because of the length callback, http_read must take this into account so that the remaining bytes are still available for future calls, before reading again from the file descriptor. 2025-10-02T13:52:14+00:00 Xavier Del Campo Romero xavi92@disroot.org 2025-09-30T21:50:33+00:00 urn:sha1:a0f5f7509bb9040752fa61fe0fdb447608e22b1c This new interface allows library users to parse application/x-www-form-urlencoded data conveniently. 2025-09-27T22:12:57+00:00 Xavier Del Campo Romero xavi92@disroot.org 2025-09-27T18:48:55+00:00 urn:sha1:94ddbec88e57fe742f219a30145650165887f22c Among other reasons, this function can be useful to sanitize user-generated content before assigning it do a node. 2025-09-24T10:33:35+00:00 Xavier Del Campo Romero xavi92@disroot.org 2025-09-23T20:03:57+00:00 urn:sha1:5a6f30440b66fe6713acb9d979dc3e6624e4c36a Sometimes, library users cannot return a HTTP response as soon as the request is received, or the operations that are required to generate it can take a long time. In order to solve this, libweb adds a new member to struct http_response, namely step, which must be assigned to a function whenever a HTTP response should be generated in a non-blocking manner. Leaving the function pointer as null will fall back to the default behaviour.
