Member Function Documentation

void dsDaemon::addChild (  pid_t    npid )  [protected, inherited]

int SimpleHttpDaemon::autoindex (  const char *    dirname )  [protected]

int dsHttpDaemon::child_work (    )  [protected, virtual, inherited]

This function does per child actions Reimplemented from dsDaemon.

const char * dsHttpDaemon::content_type (  const char *    url )  [protected, virtual, inherited]

Extract url suffx and attempt to map it to content type

int dsHttpDaemon::end_of_header (  dsStrstream &    req )  [protected, inherited]

pid_t dsHttpDaemon::fork_child (    )  [protected, virtual, inherited]

fork child. Default function increase child counter and then fork. It's better to call return dsDaemon::fork_child() at the end of overloaded function. if overloaded function returns -1 (fork error) child will not be intialised. Reimplemented from dsDaemon.

void SimpleHttpDaemon::http_common_headers (  std::ostream &    os )  [protected, virtual]

This function place daemon sign to bottom of error messages Reimplemented from dsHttpDaemon.

void dsHttpDaemon::http_request_headers (  dsStrstream &    src )  [protected, inherited]

void SimpleHttpDaemon::http_server_sign (  std::ostream &    os )  [protected, virtual]

This function add common headers to every response default implementation add local date only. Polite daemon should also add its name. Reimplemented from dsHttpDaemon.

int dsHttpDaemon::init_globals (    )  [protected, virtual, inherited]

Perform tasks after daemon detach, but before first fork all file handlers is closed to this point. Reimplemented from dsDaemon.

void dsDaemon::kill_running (    )  [inherited]

read pid file and kill running instance

int SimpleHttpDaemon::outfile (  const char *    fname, size_t    size, const char *    mime_type )  [protected]

bool dsHttpDaemon::parse_first_line (  dsStrstream &    src )  [protected, inherited]

bool dsHttpDaemon::parse_header_line (  dsStrstream &    src )  [protected, inherited]

int SimpleHttpDaemon::process_request (  dsStrstream &    src )  [protected, virtual]

Do per-request work. All found http headers placed into hashtable two meta-headers added METHOD and URL Argument src points to start of data block Reimplemented from dsHttpDaemon.

void dsDaemon::processPidFile (    )  [protected, inherited]

int dsDaemon::reinit (    )  [virtual, inherited]

Function to call from SIGHUP handler. Week point use it with care.

void dsDaemon::removeChild (  pid_t    npid )  [protected, inherited]

void dsHttpDaemon::shutdown_child (    )  [protected, virtual, inherited]

This function called when child terminated wether by SIGTERM or normally Reimplemented from dsDaemon.

void SimpleHttpDaemon::vhost_setup (  dsStrstream &    src )  [protected, virtual]

Do additional initialisation just after request header parsed. Reimplemented from dsHttpDaemon.

int dsDaemon::waitForFreeSlot (  pid_t    pid )  [protected, inherited]

Waits for free slot in child array, and returns number of found slot

Friends And Related Function Documentation

int DaemonFlags (  char *    str )  [friend, inherited]

Convert text reperesentation of daemon file into binary flags

void daemonize (  dsDaemon *    sd, int    options = 0 )  [friend, inherited]

Perform basic system tasks to become a daemon: close all handlers, allocate new process group and detach sd pointer to dsDaemon object options daemon flags

void dsSafeSleep (  int    secs, int    nsecs = 0 )  [friend, inherited]

safe sleep: implement sleep by nanosleep or select timer (TODO), instead of using SIGALARM or sleep() to avoid possible interference with user application
