package as lang/lua51.
I've adjusted the depends and switched the PKGNAMEs but these packages
are otherwise unchanged. This means that you can't install both at
once. There are preliminary patches for that (see tech-pkg) but they
aren't quite ready yet.
This also doesn't include agc's builtin.mk, although it should be
possible to drop it into the lua51 package with only very minor
modifications. I don't think the builtin packages will allow having
one builtin.mk for both lua51 and lua52, but I'd be happy to be shown
wrong about that.
Add infrastructure support for Lua module packages (including
multiversion support), application packages written in Lua, and a
redirecting bl3.mk file for packages that just link Lua in. This is
based on the Python infrastructure.
The new variable LUA_VERSION_DEFAULT picks which Lua package you get
by default; it is set to 52 so as to maintain the status quo.
Packages can set LUA_VERSIONS_ACCEPTED and/or LUA_VERSIONS_INCOMPATIBLE.
I have found (I think) most or all the packages that don't work with
lua51 and will be marking those; I have not tracked down most of the
ones that don't work with lua52 yet as I was originally intending to
roll back to 5.1 as the default.
are replaced with .include "../../devel/readline/buildlink3.mk", and
USE_GNU_READLINE are removed,
* .include "../../devel/readline/buildlink3.mk" without USE_GNU_READLINE
are replaced with .include "../../mk/readline.buildlink3.mk".
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
Changes:
* Changes from version 5.0 to 5.1
-------------------------------
Language:
+ new module system.
+ new semantics for control variables of fors.
+ new semantics for setn/getn.
+ new syntax/semantics for varargs.
+ new long strings and comments.
+ new `mod' operator (`%')
+ new length operator #t
+ metatables for all types
API:
+ new functions: lua_createtable, lua_get(set)field, lua_push(to)integer.
+ user supplies memory allocator (lua_open becomes lua_newstate).
+ luaopen_* functionst must be called through Lua.
Implementation:
+ new configuration scheme via luaconf.h.
+ incremental garbage collection.
+ better handling of end-of-line in the lexer.
+ fully reentrant parser (new Lua function `load')
+ better support for 64-bit machines.
+ native loadlib support for Mac OS X.
+ standard distribution in only one library (lualib.a merged into lua.a)
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
