Detailed Description

convenience API for writing testcases for GNUnet Many testcases need to start and stop a peer/service and this library is supposed to make that easier for TESTCASES.

Normal programs should always use functions from gnunet_{util,arm}_lib.h. This API is ONLY for writing testcases (or internal use of the testbed).

Macro Definition Documentation

◆ LOG

#define LOG (   kind,
  ... 
)    GNUNET_log_from (kind, "testing-api", __VA_ARGS__)

Definition at line 39 of file testing.c.

◆ LOW_PORT

#define LOW_PORT   12000

Lowest port used for GNUnet testing.

Should be high enough to not conflict with other applications running on the hosts but be low enough to not conflict with client-ports (typically starting around 32k).

Definition at line 48 of file testing.c.

◆ HIGH_PORT

#define HIGH_PORT   56000

Highest port used for GNUnet testing.

Should be low enough to not conflict with the port range for "local" ports (client apps; see /proc/sys/net/ipv4/ip_local_port_range on Linux for example).

Definition at line 55 of file testing.c.

Function Documentation

◆ hostkeys_load()

static int hostkeys_load ( struct GNUNET_TESTING_System system)

This function loads such keys into memory from a file.

Parameters

static int GNUNET_TESTING_configuration_create_ ( struct GNUNET_TESTING_System system,
struct GNUNET_CONFIGURATION_Handle cfg,
uint16_t **  ports,
unsigned int *  nports 
)
static

Create a new configuration using the given configuration as a template; ports and paths will be modified to select available ports on the local system.

The default configuration will be available in PATHS section under the option DEFAULTCONFIG after the call. GNUNET_HOME is also set in PATHS section to the temporary directory specific to this configuration. If we run out of "*port" numbers, return GNUNET_SYSERR.

This is primarily a helper function used internally by 'GNUNET_TESTING_peer_configure'.

Parameters
systemsystem to use to coordinate resource usage
cfgtemplate configuration to update
portsarray with port numbers used in the created configuration. Will be updated upon successful return. Can be NULL
nportsthe size of the ‘ports’ array. Will be updated.
Returns
GNUNET_OK on success, GNUNET_SYSERR on error - the configuration will be incomplete and should not be used there upon
