The * primary output format is a line of attributes (selected by -o), possibly * followed by process description lines (if -p is specified), for each * instance selected. The columns available to display are described by the * struct column columns array. The columns to actually display are kept in * the opt_columns array as indicies into the columns array. The selection * mechanisms available for this format are service FMRIs (selects all child * instances), instance FMRIs, instance FMRI glob patterns, instances with * a certain restarter (-R), dependencies of instances (-d), and dependents of * instances (-D). Since the lines must be sorted (per -sS), we'll just stick * each into a data structure and print them in order when we're done. To * avoid listing the same instance twice (when -d and -D aren't given), we'll * use a hash table of FMRIs to record that we've listed (added to the tree) * an instance. * * The secondary output format (-l "long") is a paragraph of text for the * services or instances selected. Not needing to be sorted, it's implemented * by just calling print_detailed() for each FMRI given. */ #include "svcs.h" #include "notify_params.h" /* Get the byteorder macros to ease sorting. */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #ifndef TEXT_DOMAIN #define TEXT_DOMAIN "SUNW_OST_OSCMD" #endif /* TEXT_DOMAIN */ #define LEGACY_UNKNOWN "unknown" /* Flags for pg_get_single_val() */ #define EMPTY_OK 0x01 #define MULTI_OK 0x02 /* * An AVL-storable node for output lines and the keys to sort them by. */ struct avl_string { uu_avl_node_t node; char *key; char *str; }; /* * For lists of parsed restarter FMRIs. */ struct pfmri_list { const char *scope; const char *service; const char *instance; struct pfmri_list *next; }; /* * Globals */ scf_handle_t *h; static scf_propertygroup_t *g_pg; static scf_property_t *g_prop; static scf_value_t *g_val; static size_t line_sz; /* Bytes in the header line. */ static size_t sortkey_sz; /* Bytes in sort keys. */ static uu_avl_pool_t *lines_pool; static uu_avl_t *lines; /* Output lines. */ int exit_status; ssize_t max_scf_name_length; ssize_t max_scf_value_length; ssize_t max_scf_fmri_length; static ssize_t max_scf_type_length; static time_t now; static struct pfmri_list *restarters = NULL; static int first_paragraph = 1; /* For -l mode. */ static char *common_name_buf; /* Sized for maximal length value. */ char *locale; /* Current locale. */ char *g_zonename; /* zone being operated upon */ /* * Pathname storage for path generated from the fmri. * Used for reading the ctid and (start) pid files for an inetd service. */ static char genfmri_filename[MAXPATHLEN] = ""; /* Options */ static int *opt_columns = NULL; /* Indices into columns to display. */ static int opt_cnum = 0; static int opt_processes = 0; /* Print processes? */ static int *opt_sort = NULL; /* Indices into columns to sort. */ static int opt_snum = 0; static int opt_nstate_shown = 0; /* Will nstate be shown? */ static int opt_verbose = 0; static char *opt_zone; /* zone selected, if any */ /* Minimize string constants. */ static const char * const scf_property_state = SCF_PROPERTY_STATE; static const char * const scf_property_next_state = SCF_PROPERTY_NEXT_STATE; static const char * const scf_property_contract = SCF_PROPERTY_CONTRACT; /* * Utility functions */ /* * For unexpected libscf errors.
