Createrepo_c Error Reporting

• Createrepo_c uses Glib2 error reporting style.
• Definitely look at the error.h

Error Domains

• CR_DB_ERROR
• CR_XML_DUMP_PRIMARY_ERROR
• CR_XML_DUMP_FILELISTS_ERROR
• CR_XML_DUMP_OTHER_ERROR
• ... (All return domains could be found in error.h)

Error Codes

• (0) CR_OK
• ... (All return codes could be found in error.h)

Summary about errors

• Programming errors are not reported by GError (createrepo_c lib uses asserts to prevent programming errors).
• NULL could be safely passed instead of GError** for every createrepo_c lib function.
• If an error is reported via GError then output param(s) shoud be empty (e.g. NULL value).
• If GError is used, it MUST be initialized to NULL (GError *err = NULL).

Example of usage

cr_Package *pkg;
GError *err = NULL;   // It's necessary to set err to NULL!

cr_package_parser_init();
pkg = cr_package_from_rpm("foopkg.rpm",
                          CR_SHA256,
                          "packages/foopkg.rpm",
                          NULL,
                          5,
                          NULL,
                          &err);
cr_package_parser_cleanup();
if (err != NULL) {
    printf("Error occured: %d (%s)", err->code, err->msg);
    g_error_free(err);
    return 1;
}
return 0;
