motivation: https://luapower.com/forum/topic/41/bundle-with-dofile

The current API for loading bundled files is this:

bundle.load(filename) -> string

We want to avoid creating a possibly huge string:

bundle.load(filename) -> pointer, size

For a bundled file that's trivial, but we want the same API to support loading the same file from the disk as well, transparently, so we can support transparent upgrades. For this we need to add portable support for file mmap-ing.

another cool feature would be monkey-patching the lfs API so that it transparently works with mmapped files.

and yet another feature would be accessing the file descriptor of the mmapped file so we can feed it directly to APIs that work on fds (and maybe FILE* streams too?).

Update: we already have this in fs, just need to integrate it.

This prevents dynamically linking some libraries on an otherwise static exe, unless you also link winpthreads dynamically.

Hello, I've tried to create a fat luajit exe with all the modules,

And this was the output (The first line is the command I've executed), I've executed this under git bash:

$ ./mgit bundle -a --all -m --all -o LuaJIT_Fat.exe

operable program or batch file.

Using mingw64 for 32-bit under a 64-bit machine (Because my target machine is a 32-bit one).

Add a function to package.luastate that adds the bundle loaders to newly created states.

Bundled exes are built with -mmacosx-version-min=10.6 option, but I haven't actually tested them on an OSX 10.6 yet to see if they actually work. If anyone has a 10.6 please report success or failure until I install a 10.6 or 10.7 myself.

• code review
• unit test: load bundled modules in pthreads / Lua states repeatedly and see that it doesn't crashes.

Check out https://code.google.com/p/miniz/ -- see if it's small enough that we can bundle it for specified files, to enable transparent decompression of bundled files (and maybe modules too).
