The http/ and hashtable/ Makefiles named sources that do not exist (test.c, net.c, net.h in http/; http.h in hashtable/) and had no way to find the sibling hashtable/llist sources they link against, so neither directory built at all. Both now compile those sources with explicit recipes. VPATH would be the terser fix but is deliberately avoided: it searches for targets as well as sources, so a stale ../llist/test.o gets linked in place of a freshly compiled one, and hashtable/test silently runs the linked-list suite instead of its own. llist/Makefile built fine; its .PHONY read "all," with a comma, making that the literal target name, and test.o was missing its llist.h dependency. README covers layout, build, run, the use()/Handler routing API, and the library tests. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

pico-http
A minimal HTTP server in C, with the hashtable and linked-list libraries it is built on.
Layout
http/ server and routing framework
hashtable/ route table
llist/ bucket chaining for the hashtable
Build
Needs gcc and make.
cd http && make
Run
./pico-http
Listens on port 3000, set by PORT in http/http.h.
$ curl localhost:3000/login
Login works!
$ curl localhost:3000/signup
Sign Up works!
Unregistered paths return 400 Bad request.
Adding a route
A handler fills in Res:
void hello(Req* req, Res* res)
{
char* content = "Hello\n";
res->status = 200;
res->content_type = "text/html";
res->content_length = strlen(content);
res->body = content;
}
Register it before starting the server, in main.c:
use("/hello", &hello);
http_start(PORT);
Paths match exactly — /hello will not match /hello/.
Library tests
cd llist && make && ./test
cd hashtable && make && ./test
make clean in any of the three directories removes its objects and binary.
