teranoz Report post Posted December 28, 2004 (edited) Also had a crash from coal mine to DP map. Used (unmodified) CVS files from 27 december compiled with VC 6. From windows event logs : Application popup: Eternal Lands: elc.exe - Application Error : The instruction at "0x0041d699" referenced memory at "0x1069a6e8". The memory could not be "read". Click on OK to terminate the program Click on CANCEL to debug the program Edited December 28, 2004 by teranoz Share this post Link to post Share on other sites
Wytter Report post Posted December 28, 2004 And you were using -DOPTIMIZED_LOCKS and -DPOSSIBLE_FIX? Share this post Link to post Share on other sites
teranoz Report post Posted December 28, 2004 No idea, I used the code as is (including the VC project files), only thing I changed was adding the timer files to the project, and turning off compile warnings in Release and Debug version. How should I compile with those options in VC 6 (did not get it working in VC 2005) Share this post Link to post Share on other sites
Wytter Report post Posted December 28, 2004 Try putting: #define OPTIMIZED_LOCKS #define POSSIBLE_FIX In global.h Share this post Link to post Share on other sites

Wytter Report post Posted December 29, 2004 Umm, then let me make this absolutely clear: I ONLY want to hear about crashes happening with a CVS client from the last week AND it must be compiled with -DPOSSIBLE_FIX and -DOPTIMIZED_LOCKS. Share this post Link to post Share on other sites
Malaclypse Report post Posted December 30, 2004 hello, during the last several days, (I think it happened first on 23. or 24.12) my client disconnected unexpectedly. I'm not sure if this has something to do with the map change bug, but since it never happened before in this way, i decided to report it here. The diconnection mostly happened immediately after a map change. Yesterday I exited pl storage and got disconnected. There are no resyncs or even lags right before, I just got the usual 'disconnected from server' message. One time it happened to me when somebody wanted to trade me. Just immediately after the yellow message show up, i got disconnected. This disconnections happen so fast, that I notice them only after 2 or 3 seconds. One time it happened to me during autowalk on pl map, but mostly it happens after map change. This happened to me ~6-10 times since thursday or friday last week. Is this of interest for you? If so, what can I do to help catching this down? In addition to the usually defined macros, I compile my client with -DDEBUG -DEXTRA_DEBUG and -DMUTEX_DEBUG defined. I redirect the huge amount of output created by the -DMUTEX_DEBUG macro into a log file and most time I also log the raw connection data. So there are lots of log files that may help. hth Share this post Link to post Share on other sites
Wytter Report post Posted December 30, 2004 (edited) Are you sure that it is not caused by a lagging connection? I have not been able to reproduce connection errors here at least. A good place to start would be the connection_log.txt. The cause of why it disconnected should be in one of the last messages, but since it happens so fast I'm not sure it'd give any useful information. Since it's binary data you'd normally have to use a hex editor to examine them. But I'll make a small program for examining the connection log instead Are you running the latest SDL-libs? Was there anything in the error_log.txt? Edited December 30, 2004 by Wytter Share this post Link to post Share on other sites
Wytter Report post Posted December 30, 2004 (edited) Here's the file for examining the data: http://wytter.tfm.ro/elc/examine.c I did not finish the: char * get_actor_info(unsigned char * data) char * get_stats_info(short * data) char * get_trade_info(int type, unsigned char * data) char * get_knowledge_info(int len, unsigned char * data) char * get_items_info(unsigned char * data) char * get_item_info(unsigned char *data) char * get_teleporters_info(unsigned char * data) char * get_bag_info(unsigned char * data) char * get_response_info(unsigned char * data, int len) char * get_active_spells_info(unsigned char * data) Yet as I hope it won't be necissary Edited December 30, 2004 by Wytter Share this post Link to post Share on other sites

Was there anything in the error_log.txt? No i'm not sure, that this is not because of a lagging connection. It just doesn't run like the connection were lagging. And after some of the disconnections I send ping commands to the server to check the connection. I usually doing this by sending 5-10 pings within a very short time to get an average out of them. My sdl ist libsdl-1.2.7-r3 which is the latest stable release for my distro (using gentoo, my system is quite up to date, as I sync and update it once a day). There is release 1.2.8 available within the portage repository, but as it is still marked unstable I only want to upgrade to this version if this is really necessary. My SDL_net is relesease 1.2.5, which is the latest version available for gentoo. I don't know if there was something in the error_log.txt file after the disconnections. That's my current error_log.txt after playing for ~2 hours this morning/noon: Error: Problems loading texture: ./textures/fontv.bmp Error: Problems loading texture: ./textures/particle0.bmp Error: Problems loading texture: ./textures/particle1.bmp Error: Problems loading texture: ./textures/particle2.bmp Error: Problems loading texture: ./textures/particle3.bmp Error: Problems loading texture: ./textures/particle4.bmp Error: Problems loading texture: ./textures/particle5.bmp Error: Problems loading texture: ./textures/particle6.bmp Error: Problems loading texture: ./textures/particle7.bmp Error: draw_scene.c.draw_scene:69 - OpenGL error 1284 Error: Unable to add command 23 - 61 Error: Unable to add command 25 - 1394 Error: Unable to add command 24 - 1394 Error: draw_scene.c.draw_scene:69 - OpenGL error 1284 Error: Unable to add command 24 - 1394 Error: draw_scene.c.draw_scene:69 - OpenGL error 1284 I've seen those opengl errors appearing before (not sure which error numbers though) and the errors about the missing particles first appeared yesterday or maybe on tuesday after syncing elc with CVS and recompiling. Thank you much for this examince app. I ran my current connection_log.txt through it, but didn't find any interesting, but it didn't crash either during my last playtime. Can I use examine in a way like this? ./examine `tail -f ~/.elc/connection_log.txt` or won't this produce any meaningful results? I just will try it. Should it happen again, I will not reconnect immediately, but rather shut down the client and take a look at the logs. Thanks Share this post Link to post Share on other sites
Wytter Report post Posted December 30, 2004 Well, it wouldn't create meaningful results, as I designed it to just open the file given by $1. But it could be done without too many modifications - just don't have the time today or tomorrow, but feel free to modify it - it's public domain. Share this post Link to post Share on other sites
The_Piper Report post Posted January 1, 2005 Actually im crashing not when changing maps, but sometimes after logging in. When i manage it to catch this crash in GDB and typed "where" i got only a lot of question marks and an address reported in libGLcore.so.1. Piper Share this post Link to post Share on other sites
Wytter Report post Posted January 1, 2005 Hmm, that sounds like a missing check_gl_errors(); call. Is probably your library acting up... Anyway, I think I'll merge this - seems to be working as it should... Share this post Link to post Share on other sites
Wytter Report post Posted January 7, 2005 OK, removed the #define's and made OPTIMIZED_LOCKS and POSSIBLE_FIX the normal target. Share this post Link to post Share on other sites

Wytter Report post Posted January 10, 2005 (edited) I added a small fix about 2 hours ago, that should work... Was related to inaccurate checking of whether the current actor became a null-pointer after getting a server message... I am 100% sure that was the bug you ran into.

Wytter Report post Posted January 10, 2005 0: Check your error_log.txt... 1st: Do a clean compile. 2nd: Get rules.xml 3rd: Get the textures 4th: Run it in gdb I don't think it's segfaulting, it probably just exits as it didn't find the rules... There's no segfault in that strace anyway... Share this post Link to post Share on other sites

Wytter Report post Posted January 10, 2005 Actually it was a pointer that pointed to free'd memory. The normal actor* in the actors_list was free()'d and set to 0x0, but the pointer used in display_actors() I was checking wasn't. Share this post Link to post Share on other sites
