TODO

Release critical (permanent list)

• Fix PowerPC dlopen stuff (both build and run)
• Test on 32-bit systems
• Correct unit test failures
• Change filename CRC into one based on path, not contents
• Update man page
• Update ChangeLog

Python engine

• Map last line of a multi-line string to the first on assignments
• Handle backslashes
• On exceptions, it seems the covered data is NULL:ed??
• Use a C python module and skip the FIFO stuff altogether...
• Accumulation of data is sometimes broken, unclear why

Ptrace engine

• solib: Keep current LD_PRELOAD (and add test for it)
• Use kernel 3.1 PTRACE_SEIZE, PTRACE_INTERRUPT instead of attach?
• Implement ARM-support
• Make portable to FreeBSD, Mac OS X

Kernel engine

• Test with larger modules
• Oops... Maybe use trace-kprobes.c instead...
• kprobe-coverage: Use S_IRUGO etc
• kprobe-coverage: Only allow one to open the show file
• See if something can be done about .init.text, .exit.text
• Use select() to avoid hanging on input from the kernel (allows output generation while waiting)

BASH engine

• Update shcov bug reports that have been fixed with kcov

ELF parser

• Rewrite to use libbfd
• Show unreachable code somehow (e.g., to detect goto fail; goto fail; dead code-type of errors)
• Add --verify option which disassembles symbols before setting breakpoints: Throw away entries in the middle of instructions

Server mode

• Separate output dir and database dir for --report-only
• Make it possible to supply multiple binaries for --report-only
• Produce database files of addresses-to-instrument so that binaries without symbols can be used
• (Above) --create-database
• Add a shared library that can be LD_PRELOAD:ed for coverage

Output

• Add --merge option to just merge multiple output directories
• Add robot framework test for --include/exclude-path.
• File locking to avoid races

Web pages

• Code highlighting
• Make marked lines extend to the end of the line

Misc

• Use uint64_t for addresses
• Make ptrace build optional
• Provide a hash-bang binary that does kcov collection (for python, shell etc)
