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`.
|
|
|
|
```sh
|
|
cd http && make
|
|
```
|
|
|
|
## Run
|
|
|
|
```sh
|
|
./pico-http
|
|
```
|
|
|
|
Listens on port 3000, set by `PORT` in `http/http.h`.
|
|
|
|
```sh
|
|
$ 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`:
|
|
|
|
```c
|
|
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`:
|
|
|
|
```c
|
|
use("/hello", &hello);
|
|
http_start(PORT);
|
|
```
|
|
|
|
Paths match exactly — `/hello` will not match `/hello/`.
|
|
|
|
## Library tests
|
|
|
|
```sh
|
|
cd llist && make && ./test
|
|
cd hashtable && make && ./test
|
|
```
|
|
|
|
`make clean` in any of the three directories removes its objects and binary.
