Presents files, namespaces, types and variables in a manner similar to doxygen.\n* supports the debuginfod protocol to download debug information\n* Coredump parser: \n    * identify all C++ objects in memory that possess virtual methods. This works even for stripped binaries.\n    * identify all allocations allocated or freed by glibc malloc. This requires debug information for the C library and ld.so\n    * identify memory leaks and references into freed allocations (temporarily not exposed in UI until refactoring is complete)\n    * unwind the stack for all threads and display local variables and function parameters. Requires unwind information in the Itanium ABI, does not support compact unwind information used by 32-bit ARM.\n\n![Dark Theme](images/namespace_std_dark.png)\n![Light Theme](images/namespace_std_light.png)\n\nWork in progress:\n* find the shortest possible name for C++ types and functions\n* using debug information, recursively follow all pointers in identified objects on the stack, heap, global variables and thread local storage\n* search and queries\n\nLimitations:\n* Platform dependent features have only been implemented for x86-64 and aarch64.\n* Only tested with user space applications and only on Linux, support for FreeBSD is in progress.\n* If you run this in your web browser, you are limited to 2GB total memory.\n* It does not have progress bars.\n\nI have created a selection of core dumps with various problems:\n*  [Invalid pointer derefence](https://core-explorer.github.io/core-explorer/index-st.html?download=https://core-explorer.github.io/binary-samples/cpp-examples/x86_64-Debug-bookworm/PointerExample.gdb.core\u0026download1=https://core-explorer.github.io/binary-samples/cpp-examples/x86_64-Debug-bookworm/PointerExample)\n* [Calling a virtual function from a base class](https://core-explorer.github.io/core-explorer/index-st.html?download=https://core-explorer.github.io/binary-samples/cpp-examples/x86_64-Debug-noble/VirtualExample.gdb.core\u0026download1=https://core-explorer.github.io/binary-samples/cpp-examples/x86_64-Debug-noble/VirtualExample)\n* [leaking memory](https://core-explorer.github.io/core-explorer/index-st.html?download=https://core-explorer.github.io/binary-samples/cpp-examples/x86_64-Debug-bookworm-clang/NewExample.gdb.core\u0026download1=https://core-explorer.github.io/binary-samples/cpp-examples/x86_64-Debug-bookworm-clang/NewExample)\n* [Corrupting malloc metadata](https://core-explorer.github.io/core-explorer/index-st.html?download=https://core-explorer.github.io/binary-samples/cpp-examples/x86_64-Debug-noble/VectorExample.gdb.core\u0026download1=https://core-explorer.github.io/binary-samples/cpp-examples/x86_64-Debug-noble/VectorExample)\n\n\n![Memory Leaks](images/memory_leak_light.png)\n\n## Standalone Application ##\n\nThere is also a standalone node.js application [cdx.js](README_cdx.md).\n\n## Important: ##\n*Do not leak client data by sharing core dumps.* \n\n*Do not leak confidential information by sharing debug information.*\n\nCore Explorer runs exclusively in your browser, all uploads happen inside your browser.\nYour files are never stored anywhere. Core Explorer does not use tracking, analytics or cookies.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcore-explorer%2Fcore-explorer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcore-explorer%2Fcore-explorer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcore-explorer%2Fcore-explorer/lists"}
