Bug#321064: Clearing of passwords does not happen
Hello, For now I have no idea. I'll try reproduce the bug with valgrind. Simon Le Vendredi 5 Août 2005 13:05, Martin Samuelsson a écrit : Samuel Mimram @ 2005-08-04 (Thursday), 19:12 (+0200) In the preferences dialog under the SIP tab there is a button to: Clear all stored authentication information However, when using it nothing happens. All information is still present in ~/.gnome2/linphone Clicking the same dialog twice results in a crash. Thanks for the report. I did not manage to make linphone crash by clicking twice. Could you give me a gdb stack trace? I'm providing one below. Although I don't know if it has enough information. Please let me know if there's anything else I should do.

Simon Morlat @ 2005-08-24 (Wednesday), 23:27 (+0200) Hello, Hi there, For now I have no idea. I'll try reproduce the bug with valgrind. That's an idea I never though of, and silly enough it still chrashes for me when running it through valgrind. :/ I'm not an total expert on valgrind either, but my expection was that a memory access error shouldn't result in a chrash... Spending a few minutes actually stepping through with gdb made me find something suspicious. Applying the attached patch fixes the problem for me, but I guess it's time to do an audit if more things are coded the way that they assume g_list_free() should NULL the pointer. -- /Martin --- linphone-1.0.1/coreapi/authentication.c 2005-03-10 17:59:41.0 +0100 +++ linphone-1.0.1-nocrash/coreapi/authentication.c 2005-08-25 15:37:23.974222897 +0200 @@ -185,6 +185,7 @@ linphone_auth_info_write_config(lc-config,NULL,i); } g_list_free(lc-auth_info); + lc-auth_info = NULL; } gboolean linphone_core_find_or_ask_for_auth_info(LinphoneCore *lc,const char *username,const char* realm, gboolean force_ask)
Bug#321064: Clearing of passwords does not happen
Hello, Great investigation ! In the 1.1.0 release I use the bug was fixed (I did not remember), that 's why it could not happen, even with valgrind.
