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. 2025-09-24T10:33:35+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. 2024-08-25T12:31:21+00:00 Xavier Del Campo Romero xavi.dcr@tutanota.com 2024-08-25T12:31:21+00:00 urn:sha1:43a39a1f2e5e6c7c520f03293fc57aa76fea8aaf libweb is meant to be silent during normal operation, thus only printing to stderr on errors. 2024-08-22T00:27:34+00:00 Xavier Del Campo Romero xavi.dcr@tutanota.com 2024-08-19T22:07:05+00:00 urn:sha1:43e89fb23943b5ffb6854f290592c29cd079bf46 So far, libweb installed a signal handler so as to handle SIGTERM, SIGPIPE and SIGINT signals so that processes would not have to care about such details. However, it is not advisable for libraries to install signal handlers, as signals are handled on a per-process basis. The previous approach would be incompatible if several instances of the library were allocated by the same process. Unfortunately, this has the undesired side effect of adding the boilerplate code into the process. 2024-02-19T22:00:56+00:00 Xavier Del Campo Romero xavi.dcr@tutanota.com 2024-02-19T22:00:56+00:00 urn:sha1:afe0681c0b26bb64bad55d7e86770f346cfa043e A malicious user could inject an infinite number of empty files or key/value pairs into a request in order to exhaust the device's resources. 2023-11-20T15:27:28+00:00 xavi xavi@noreply.localhost 2023-11-20T15:27:28+00:00 urn:sha1:8f1ad3124e9e063ca0ee7c2548c747b20de3529d Reviewed-on: https://gitea.privatedns.org/xavi/libweb/pulls/2 2023-11-20T15:25:58+00:00 Xavier Del Campo xavier.delcampo@midokura.com 2023-11-20T11:20:51+00:00 urn:sha1:59a67a7541ee1559b140494c21a25b195246a4fa Even if server_client_close fails, it is needed for client_free to remove the dangling reference from h->clients. 2023-11-20T15:06:19+00:00 Xavier Del Campo xavier.delcampo@midokura.com 2023-11-16T11:23:08+00:00 urn:sha1:98f5f52461b0c1ab1ee3331722bd32e2db9e1d41 Some applications might set up a struct handler object to listen on any port i.e., 0, but still need a way to determine which port number was eventually selected by the implementation. Therefore, handler_listen has been reduced to the server initialization bit, whereas the main loop has been split into its own function, namely handler_loop. Because of these changes, it no longer made sense for libweb to write the selected port to standard output, as this is something now applications can do on their own.
