Here's my tips: 1. General C tricks - learn to use vim or emacs & read their manuals; customize to suite your style - use vim w/ pathogen plugins for auto formatting (don't use tabs!) & syntax - use ctags to jump around functions - Use ASAN & valgrind to check for memory leaks and heap corruption - learn to use "git bisect" to quickly find where regressions were introduced & revert them - Use a window manager like tmux or screen 2. Gluster specific tricks - Alias "ggrep" to grep through all Gluster source files for some string and show you the line numbers - Alias "gvim" or "gemacs" to open any source file without full path, eg. "gvim afr.c" - GFS specific gdb macros to dump out pretty formatting of various structs (Jeff Darcy has some of these IIRC) - Write prove tests...for everything you write, and any bug you fix. Make them deterministic (timing/races shouldn't matter). - Bugs/races and/or crashes which are hard or impossible to repro often require the creation of a developer specific feature to simulate the failure and efficiently code/test a fix. Example: "monkey-unlocking" in the lock revocation patch I just posted. - That edge case you are ignoring because you think it's impossible/unlikely? We will find/hit it in 48hrs at large scale (seriously we will) ....handle it correctly or at a minimum write a (kernel style) "OOPS" log type message. That's all I have off the top of my head. I'll give example aliases in another reply.
