If you want/need to use it in a multi-threaded app. Please + adjust accordingly. + + +Build + + Rebuild libcurl with -DCURLDEBUG (usually, rerunning configure with + --enable-debug fixes this). 'make clean' first, then 'make' so that all + files actually are rebuilt properly. It will also make sense to build + libcurl with the debug option (usually -g to the compiler) so that debugging + it will be easier if you actually do find a leak in the library. + + This will create a library that has memory debugging enabled. + +Modify Your Application + + Add a line in your application code: + + curl_memdebug("dump"); + + This will make the malloc debug system output a full trace of all resource + using functions to the given file name. Make sure you rebuild your program + and that you link with the same libcurl you built for this purpose as + described above. + +Run Your Application + + Run your program as usual. Watch the specified memory trace file grow. + + Make your program exit and use the proper libcurl cleanup functions etc. So + that all non-leaks are returned/freed properly. + +Analyze the Flow + + Use the tests/memanalyze.pl perl script to analyze the dump file: + + tests/memanalyze.pl dump + + This now outputs a report on what resources that were allocated but never + freed etc. This report is very fine for posting to the list! + + If this doesn't produce any output, no leak was detected in libcurl. Then + the leak is mostly likely to be in your code. |
