I'm almost done with server.c but can't seem to find the last error which doesn't allow me to pass check50.
I tried to analyse the existing responses to similar questions but couldn't use them to find my bug. Any help would be very much appreciated!

The errors I recieve are:

1. :( Requesting cat.jpg returns 200, image/jpeg, and correct image
2. :( Requesting /test/ outputs /test/index.html
3. :( Requesting directory containing index.php outputs index.php
4. :( Requesting two files in a row (cat.html then cat.jpg) succeeds

Given these errors I suppose there is some existing problem with jpg's and php's. The second one is strange though because I checked with GDB that the indexes function returns the correct path as a result when asked for index.html.


Load Function:  
  
    bool load(FILE* file, BYTE** content, size_t* length)
    {
        *content = NULL;
        *length = 0;
        *content = malloc(512 * sizeof(BYTE));
        if (*content == NULL)
            {
                return false;
            }
        size_t size = fread(*content, sizeof(BYTE), 512, file);
        while (size > 0)
        {   
            *length += size;
            *content = realloc(*content, *length * sizeof(BYTE));
            if (*content == NULL)
            {
                return false;
            }
            size = fread(*content + *length, sizeof(BYTE), 512, file);
        }
        return true;
    }

EDIT #1
My jpg convertion in the lookup function:

    else if (strcasecmp(final, ".jpg") == 0)
        {
            mime = "image/jpeg";
        }

The error in Check50 is: \ expected an exit code of 0, not standard error of "======= Backtrace: =========\n======= M..."
except for index.php where the error is: \ expected output, not standard error of "======= Backtrace: =========\n======= M..."

My indexes function seems to be ok, here it is:

    char* indexes(const char* path)
    {
        // ensure path is readable and executable
        if (access(path, R_OK | X_OK) == -1)
        {
            error(403);
            return NULL;
        }
        char* path1 = malloc(60);
        if (path1 == NULL)
        {
            return NULL;
        }
        strcpy(path1, path);
        char* path2 = malloc(50);
        if (path2 == NULL)
        {
            return NULL;
        }
        strcpy(path2, path);
        strcat(path1, "index.php");
        strcat(path2, "index.html");
        // check if index.html or index.php exists and returns else returns NULL
        if (access(path1, R_OK) != -1)
        {
            return path1;
        }
        else if (access(path2, R_OK) != -1)
        {
            return path2;
        }
        else
        {
            return NULL;   
        }    
    }
