- cut up those huge include files into separate interfaces for all modules.
Put the interface documentation there, and not with the implementation.
- light-weight includes for needed concrete types (lst_t.h, timestamp_t.h).
- cut out some more logically separate parts: cmd_exec, varname, parsevar,
timestamp.
- put all error handling functions together, so that we will be able to
clean them up.
- more systematic naming: functioni to handle interval, function to handle
string.
- put the init/end code apart to minimize coupling.
- kill weird types like ReturnStatus and Boolean. Use standard bool (with a
fallback for non-iso systems)
- better interface documentation for lots of subsystems.
As a result, make compilation goes somewhat faster (5%, even considering
the largish BSD copyrights to read). The corresponding preprocessed
source goes down from 1,5M to 1M.
A few minor code changes as well: Parse_DoVar is no longer destructive.
Parse_IsVar functionality is folded into Parse_DoVar (as it knows what an
assignment is), a few more interval handling functions. Avoid calling
XXX_End when they do nothing, just #define XXX_End to nothing.
Parse_DoVar is slightly more general: it will handle compound assignments
as long as they make sense, e.g., VAR +!= cmd
will work. As a side effect, VAR++=value now triggers an error
(two + in assignment).
- this stuff doesn't occur in portable Makefiles.
- writing VAR++ = value or VAR+ +=value disambiguates it.
- this is a good thing, it uncovered a bug in bsd.port.mk.
Tested by naddy@. Okayed millert@. I'll handle the fallback if there is
any. This went through a full make build anyways, including isakmpd
(without mickey's custom binutils, as he didn't see fit to share it with me).

Numerous changes:
- generate can build several tables
- style cleanup
- statistics code
- use variable names throughout (struct Name)
- recursive variables everywhere
- faster parser (pass buffer along instead of allocating multiple copies)
- correct parser. Handles comments everywhere, and ; correctly
- more string intervals
- simplified dir.c, less recursion.
- extended for loops
- sinclude()
- finished removing extra junk from Lst_*
- handles ${@D} and friends in a simpler way
- cleaned up and modular VarModifiers handling.
- recognizes some gnu Makefile usages and errors out about them.
Additionally, some extra functionality is defined by FEATURES. The set of
functionalities is currently hardcoded to OpenBSD defaults, but this may
include support for some NetBSD extensions, like ODE modifiers.
Backed by miod@ and millert@, who finally got sick of my endless patches...

Define two possible interfaces: the classic one,
and the new one (used where available) that depends on timespec.
Better granularity, make is now able to distinguish between files that
were built during the same second.

* Buf_Destroy can be a macro
* X_ instead of _X for struct names, to avoid infringing on the system's
namespace.
* better wildcard detection heuristics
* fix #ifdef CLEANUP code
* a few comments

Replace the time stamp hash in dir.c with an open hashing structure.
In doing so, remove some nasty casts, simplify code a bit:
Dir_MTime can return a modification time, since make does not make
a distinction between out-of-date and non-existent files.

open hashing.
An interesting optimization is that the open hashing interface is more
fine-grained, hence we can compute the correct hash value at the start
of Dir_FindFile, and reuse it for each hash structure into which we look
(the effect is measurable on large directories along with objdir/VPATH).
Remove a few unnecessary Lst_Open/Lst_Close that serve no purpose except
obfuscating the code.
The interface to dir.h changes slightly, hence tedious includes changes...

the disk or from a cache.
- use it in Dir_AddDir, and directly to set up dot.
- change Dir_AddDir to use string intervals, as this simplifies
dependend functions.
- set up an open-hashing cache for opened directory names.
- add_dirpath() function in main, to simplify code.
- simplify cleaning-up directories, as Dir_ClearPath is overkill.

- UNUSED macro that expands to __attribute__((unused)) for gcc
- move rcsid around so that they can be tagged UNUSED.
- activate -Wunused.
- use UNUSED instead of kludgy junk for function arguments.
- add extern to all extern prototypes.
- update comments in lst.h.
- clean up var.c a little bit, constifying arguments, updating comments...
|
|
|
|
- let *_MTime return booleans, as that's what they're used for, the time_t
is set as a side effect.
- use OUT_OF_DATE for a date starting point, set it at the origin of time.
|
|
- don't interfere with MACHINE/MACHINE_ARCH defines for bootstrap
- type clean-up, time_t, and printing `unknown' ints
- fix TARGET/MEMBER bug in archive rules
- memmove...
- cleaner Error handler.
- reentrant brk_string
- .MAKE env variable
- preliminary scaffolding for .NOPATH
Other improvements:
- efree
- shellneed streamlined
- display Stop in .CURDIR after an error.
- document most features and misfeatures.
- add a few OpenBSD notes to the tutorial.
|
|
- Merge in FreeBSD and Lite2 changes.
- Fix bug where a non-archive target with a .a suffix would always
be considered to be out of date, since it does not have a TOC.
- Fix NetBSD PR #2930: declare missing variable.
