First do "make" and - see if your platform is listed. If so, just do "make xxx", where xxx - is your platform name. The platforms currently supported are: - aix ansi bsd freebsd generic linux macosx mingw posix solaris - - If your platform is not listed, try the closest one or posix, generic, - ansi, in this order. - - See below for customization instructions and for instructions on how - to build with other Windows compilers. - - If you want to check that Lua has been built correctly, do "make test" - after building Lua. Also, have a look at the example programs in test. - -* Installing Lua - -------------- - Once you have built Lua, you may want to install it in an official - place in your system. In this case, do "make install". The official - place and the way to install files are defined in Makefile. You must - have the right permissions to install files. - - If you want to build and install Lua in one step, do "make xxx install", - where xxx is your platform name. - - If you want to install Lua locally, then do "make local". This will - create directories bin, include, lib, man, and install Lua there as - follows: - - bin: lua luac - include: lua.h luaconf.h lualib.h lauxlib.h lua.hpp - lib: liblua.a - man/man1: lua.1 luac.1 - - These are the only directories you need for development. - - There are man pages for lua and luac, in both nroff and html, and a - reference manual in html in doc, some sample code in test, and some - useful stuff in etc. You don't need these directories for development. - - If you want to install Lua locally, but in some other directory, do - "make install INSTALL_TOP=xxx", where xxx is your chosen directory. - - See below for instructions for Windows and other systems. - -* Customization - ------------- - Three things can be customized by editing a file: - - Where and how to install Lua -- edit Makefile. - - How to build Lua -- edit src/Makefile. - - Lua features -- edit src/luaconf.h. - - You don't actually need to edit the Makefiles because you may set the - relevant variables when invoking make. - - On the other hand, if you need to select some Lua features, you'll need - to edit src/luaconf.h. The edited file will be the one installed, and - it will be used by any Lua clients that you build, to ensure consistency. - - We strongly recommend that you enable dynamic loading. This is done - automatically for all platforms listed above that have this feature - (and also Windows). See src/luaconf.h and also src/Makefile. - -* Building Lua on Windows and other systems - ----------------------------------------- - If you're not using the usual Unix tools, then the instructions for - building Lua depend on the compiler you use. You'll need to create - projects (or whatever your compiler uses) for building the library, - the interpreter, and the compiler, as follows: - - library: lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c - lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c - ltable.c ltm.c lundump.c lvm.c lzio.c - lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c - ltablib.c lstrlib.c loadlib.c linit.c - - interpreter: library, lua.c - - compiler: library, luac.c print.c - - If you use Visual Studio .NET, you can use etc/luavs.bat in its - "Command Prompt". - - If all you want is to build the Lua interpreter, you may put all .c files - in a single project, except for luac.c and print.c. Or just use etc/all.c. - - To use Lua as a library in your own programs, you'll need to know how to - create and use libraries with your compiler. - - As mentioned above, you may edit luaconf.h to select some features before - building Lua. - -(end of INSTALL) diff --git a/lib/lua/README b/lib/lua/README deleted file mode 100644 index 11b4dff70..000000000 --- a/lib/lua/README +++ /dev/null @@ -1,37 +0,0 @@ -README for Lua 5.1 - -See INSTALL for installation instructions. -See HISTORY for a summary of changes since the last released version. - -* What is Lua? - ------------ - Lua is a powerful, light-weight programming language designed for extending - applications.

  • mode: ^(The mode parameter may be set to either "ro", "rw", -** "rwc", or "memory". Attempting to set it to any other value is -** an error)^. -** ^If "ro" is specified, then the database is opened for read-only -** access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the -** third argument to sqlite3_open_v2(). ^If the mode option is set to -** "rw", then the database is opened for read-write (but not create) -** access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had -** been set. ^Value "rwc" is equivalent to setting both -** SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE. ^If the mode option is -** set to "memory" then a pure [in-memory database] that never reads -** or writes from disk is used. ^It is an error to specify a value for -** the mode parameter that is less restrictive than that specified by -** the flags passed in the third parameter to sqlite3_open_v2(). -** -**
  • cache: ^The cache parameter may be set to either "shared" or -** "private". ^Setting it to "shared" is equivalent to setting the -** SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to -** sqlite3_open_v2(). ^Setting the cache parameter to "private" is -** equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit. -** ^If sqlite3_open_v2() is used and the "cache" parameter is present in -** a URI filename, its value overrides any behavior requested by setting -** SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag. -**

The system is said to be in -** a deadlocked state if connection A has registered for an unlock-notify -** callback on the conclusion of connection B's transaction, and connection -** B has itself registered for an unlock-notify callback when connection -** A's transaction is concluded. ^Indirect deadlock is also detected, so -** the system is also considered to be deadlocked if connection B has -** registered for an unlock-notify callback on the conclusion of connection -** C's transaction, where connection C is waiting on connection A. ^Any -** number of levels of indirection are allowed. -** -** The "DROP TABLE" Exception -** -** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost -** always appropriate to call sqlite3_unlock_notify(). There is however, -** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement, -** SQLite checks if there are any currently executing SELECT statements -** that belong to the same connection. If there are, SQLITE_LOCKED is -** returned. In this case there is no "blocking connection", so invoking -** sqlite3_unlock_notify() results in the unlock-notify callback being -** invoked immediately. If the application then re-attempts the "DROP TABLE" -** or "DROP INDEX" query, an infinite loop might be the result. -** -** One way around this problem is to check the extended error code returned -** by an sqlite3_step() call. ^(If there is a blocking connection, then the -** extended error code is set to SQLITE_LOCKED_SHAREDCACHE.

A RESERVED_LOCK is obtained by locking -** a single byte of the file that is designated as the reserved lock byte. -** A PENDING_LOCK is obtained by locking a designated byte different from -** the RESERVED_LOCK byte. -** -** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available, -** which means we can use reader/writer locks.

I'm guessing that isn't likely to happen, but by -** using the same locking range we are at least open to the possibility. -** -** Locking in windows is manditory. For this reason, we cannot store -** actual data in the bytes used for locking. The pager never allocates -** the pages involved in locking therefore. SHARED_SIZE is selected so -** that all locks will fit on a single page even at the minimum page size. -** PENDING_BYTE defines the beginning of the locks.
