* stand: liblua: add a pager moduleKyle Evans2020-12-121-0/+1
| | | | | | | | | | | | | | | This is nearly a 1:1 mapping of the pager API from libsa. The only real difference is that pager.output() will accept any number of arguments and coerce all of them to strings for output using luaL_tolstring (i.e. the __tostring metamethod will be used). The only consumer planned at this time is the upcoming "show-module-options" implementation. MFC after: 1 week Notes: svn path=/head/; revision=368591
* lualoader: drop the filename and word "LUA" from errorsKyle Evans2020-06-031-1/+1
| | | | | | | | | | | | | | | | | | The filename is nearly always wrong since it's /boot/lua/loader.lua, which is not useful for diagnostics. The actual errmsg will include a lua filename if this is relevant. Dropping "LUA" while we're here because that's almost universally irrelevant to whatever error follows, unless the error states that it's actually a lua problem. Both of these are minor nits that just detract from identifying the pertinent information. MFC after: 3 days Notes: svn path=/head/; revision=361763

* lualoader: disable autoboot on high-level interpreter errorsKyle Evans2020-02-121-0/+1
| | | | | | | | | | | | | | If we hit an error at this level, we are almost certainly not in any kind of sane state where autoboot can do the right thing. Instead of letting it try and probably failing, disable autoboot so they immediately get kicked into a loader prompt for manual remediation/diagnosis.

* stand: consolidate knowledge of lua pathKyle Evans2019-11-021-1/+3
| | | | | | | | | | | | | Multiple places coordinate to 'know' where lua scripts are installed. Knock this down to being formally defined (and overridable) in exactly one spot, defs.mk, and spread the knowledge to loaders and liblua alike. A future commit will expose this to lua as loader.lua_path, so it can build absolute paths to lua scripts as needed. MFC after: 1 week Notes: svn path=/head/; revision=354245
* userboot: handle guest interpreter mismatches more intelligentlyKyle Evans2018-09-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The switch to lualoader creates a problem with userboot: the host is inclined to build userboot with Lua, but the host userboot's interpreter must match what's available on the guest. For almost all FreeBSD guests in the wild, Lua is not yet available and a Lua-based userboot will fail. This revision updates userboot protocol to version 5, which adds a swap_interpreter callback to request a different interpreter, and tries to determine the proper interpreter to be used based on how the guest /boot/loader is compiled. This is still a bit of a guess, but it's likely the best possible guess we can make in order to get it right. The interpreter is now embedded in the resulting executable, so we can open /boot/loader on the guest and hunt that down to derive the interpreter it was built with. Using -l with bhyveload will not allow an intepreter swap, even if the loader specified happens to be a userboot with the wrong interpreter. We'll simply complain about the mismatch and bail out. For legacy guests without the interpreter marker, we assume they're 4th. For new guests with the interpreter marker, we'll read it and swap over to the proper interpreter if it doesn't match what the userboot we're using was compiled with. Both flavors of userboot are installed by default, userboot_4th.so and userboot_lua.so. This fixes the build WITHOUT_FORTH as a coincidence, which was broken by userboot being forced to 4th.

* lualoader: Add ability to intercept cli commandsKyle Evans2018-02-201-7/+27
| | | | | | | | | | | | | | | | | If we failed to execute the input line as pure lua, run the command through parse for consistent argument parsing. Pass the parsed arguments through to a global "cli_execute" written in Lua, which is expected to either handle it or pass it back through to interp_builtin_cmd (via loader.command). lua-handled cli commands will then exist as globals in whatever module they most belong in, and invocations at the loader prompt will magically dispatch to them if they exist.

* Add Lua as a scripting langauge to /boot/loaderWarner Losh2018-02-121-0/+164
liblua glues the lua run time into the boot loader. It implements all the runtime routines that lua expects. In addition, it has a few standard 'C' headers that nueter various aspects of the LUA build that are too specific to lua to be in libsa. Many refinements from the original code to improve implementation and the number of included lua libraries. Use int64_t for lua_Number. Have "/boot/lua" be the default module path. Numerous cleanups from the original GSoC project, including hacking libsa to allow lua to be built with only one change outside luaconf.h. Add the final bit of lua glue to bring in liblua and plug into the multiple interpreter framework, previously committed. Add LOADER_LUA option, currently off by default. Presently, this is an experimental option. One must opt-in to using this by defining WITH_LOADER_LUA and WITHOUT_FORTH. It's been lightly tested, so keep a backup copy of your old loader handy. The menu code, coming in the next commit, hasn't been exhaustively tested. A LUA boot loader is 60k larger than a FORTH one, which is 80k larger than a no-interpreter one. Subtle changes in size may tip things past some subtle limit (the binary is ~430k now when built with LUA). A future version may offer coexistance. Bump FreeBSD version to 1200058 to mark the milestone. Pedro Souza's 2014 Summer of Code project. Rui Paulo, Pedro Arthur, Zakary Nafziger and Wojciech A. Koszek also contributed.
