Larry Ewing hit a bug in cairo-trace whereby it tried to create a similar surface referencing an undefined object. This fix checks whether the object has yet to be defined, and if not issues an index in order to copy the appropriate operand from the stack. |

Cairo Utilities =============== There are a varieties of utilities we use with cairo. backtrace-symbols ----------------- This is a small shared library designed to be preloaded by the linker and its purpose is to make the backtrace_symbols() function of glibc produce more useful source reference information. Build by: make backtrace-symbols.so and use by: LD_PRELOAD=$PWD/backtrace-symbols.so app-to-run This code should be contributed back to glibc at some point. malloc-stats ------------ This is a small shared library designed to be preloaded by the linker and its purpose is to make the malloc_stats() function of glibc produce more useful information. Build by: make malloc-stats.so and use by: LD_PRELOAD=$PWD/malloc-stats.so app-to-run This works best when backtrace-symbols is in use. That is: LD_PRELOAD="$PWD/backtrace-symbols.so $PWD/malloc-stats.so" app-to-run cairo-trace ----------- This tool can be used to trace all the cairo function calls made by an applications. This is useful for either extracting a test case triggering a bug from an application, or simply to get a general idea of how an application is using cairo. cairo-api-update and xr2cairo ----------------------------- These two scripts were used to convert source code written for pre-1.0 cairo to newer API. See $(top_srcdir)/PORTING_GUIDE for more information. These files are obsolete now and may be removed in a future version. cairo-view and waterfall ------------------------ These are two pycairo scripts useful for testing the toy font backend.
