Hi, Ole, The ...get_lfn_wc() function is probably the only way to get all the LFNs from a LRC. In terms of why it is running slow, you might reconsider your use of the "std:vector<...>" template. Whenever you are using "push_back(...)" it may need to reallocate the underlying array. In such case, the operation becomes very expensive and may (I'm not sure) have something to do with why your code is running so slow. Also, the crash (...mmalloc... related) could be related to that vector of yours but we'd need more detail from the stack trace to know.
I might add a get_all_lfn(...) type function to a list of feature enhancements, at least so I can discuss it with other users. But for now the wildcard approach is the only way to get the info you want. rob -----Original Message----- From: [EMAIL PROTECTED] on behalf of Ole Weidner Sent: Thu 1/17/2008 1:12 PM To: [email protected] Subject: [gt-user] RLS: list LFNs Aloha, I'm implementing a replica management abstraction on top of the Globus RLS C API. So far, I was quite successful but I got stuck when I tried to retrieve a list of all available LFNs from a LRC. AFAIK there's no API call to do that directly, so I used globus_rls_client_lrc_get_lfn_wc() function with "*" as a wildcard which should give me a list of all LFNs. The code looks like this: std::vector<std::string> LFNList; globus_result_t result = GLOBUS_FALSE; int offset=0; globus_list_t * result_list; result = globus_rls_client_lrc_get_lfn_wc(RLSHandle, "*", rls_pattern_unix, &offset, 200, // reslimit &result_list); if (result != GLOBUS_RLS_SUCCESS) { throw globus_rls_replica_adaptor::exception(result); } else { globus_list_t *p; globus_rls_string2_t *str2; for (p = result_list; p; p = globus_list_rest(p)) { str2 = (globus_rls_string2_t *) globus_list_first(p); LFNList.push_back(std::string(str2->s1)); } globus_rls_client_free_list(p); globus_rls_client_free_list(result_list); } It seems to work but I'm not very satisfied with the results: * It's _incredibly_ sloooooow * If a LFN has n different PFNs, the LFN shows up n-times in the result list * If I don't use "*" as wildcard string (e.g. "/MY/REPLICAS/*") the app crashes after some time: test_rls_replica(9291,0xa0672f60) malloc: *** mmap(size=2097152) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug test_rls_replica(9291,0xa0672f60) malloc: *** mmap(size=2097152) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug terminate called after throwing an instance of 'St9bad_alloc' what(): St9bad_alloc Has anybody experienced something similar or does anybody know a better solution to list LFNs? Any help is much appreciated! Cheers, Ole
