- allow variables in SysV modifiers, as requested by matthieu@
(since recursive variables are an extension, this just extends the
extension)
- variation on :Q called :QL (quote list), which does quote every character
EXCEPT for whitespace. e.g.,
toto:
@for i in ${VAR:QL} ...

- systematically reorder jobs based on who did output last, so that the
last job to output is *first* to output again.
- better reaction to errors: any job that outputs is checked for termination
directly, and the Error message is printed right afterwards.
- better error messages, giving more useful information in -j mode.

the list item with lst_member is non-sensical, create a new function
(Lst_ForEachNodeWhile) that iterates through lstnodes directly and use
it.
Less obfuscated, slightly more efficient...

rescinded 22 July 1999. Proofed by myself and Theo.

initialize create in main.c.

pointers is simpler than calling a function.
Recognize purely static lst headers, which don't really need any
initialization.

Removes remaining lint stuff from lst.lib.

- 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...

- 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...

- audit code for Lst_Datum, it's never applied to an empty pointer,
so check can be removed -> turn into a macro,
- Lst_First, Lst_Last can become macro as well
- specialized version of Lst_Succ (Lst_Adv) to use in loops where it cannot
fail,
- Lst_Open can no longer fail. Trim down corresponding code.

- replaces Lst_Duplicate with Lst_Clone, which does not allocate storage
- split Lst_Concat into Lst_Concat/Lst_ConcatDestroy
Thus, all the LstValid checks are gone, since we always invoke list
functions with valid pointers.
Note that dynamic list allocation accounted for roughly 20% of all calls
to malloc. The extraneous calls to malloc left are now mostly in parse.c,
which makes some wasteful usage of temporary buffers.
With those few patches, the code is sturdier, and easier to maintain.

Lst_Init (constructor) and Lst_New (allocation + construction)
Lst_Destroy (destructor) and Lst_Delete (deallocation + destruction),
and uses that to turn most dynamic allocation of lists (Lst pointers)
into static structures (LIST).
Most of this is mundane, except for allGNs in targ.c, where the code must
be checked to verify that Targ_Init is called soon enough.
Lst_New is a temporary addition. All lists will soon be static.
Reviewed by millert@, like the previous patch.

C is not well-suited for opaque data structures.
Then it proceeds by removing a lot of non-sensical casts and white space.
There are two motivations behind this change:
* small functions like Lst_First can now be redefined as macros safely
(otherwise, the cast would mean that you might write Lst_First(5) and
find out about it rather late)
* the size of the Lst data structure is exposed to user code. This will
be used to allocate lists statically, instead of malloc/free them like
crazy.

In fact, it can become a macro based on Lst_ForEachFrom.
This also introduces Lst_Every, as a shortcut for the very common case where
Lst_ForEach does not need any user data.
Finally, make consistent use of a few function typedefs, instead of having
explicit void (*)(Lst) arguments all over the place.

Lst_AtEnd, Lst_Concat, Lst_Remove, Lst_Replace.
Don't bother returning one.
|

Get rid of them.
Get rid of list.h, nothing uses it anyway.

- .MAKE env variable
- preliminary scaffolding for .NOPATH
Other improvements:
- efree
- shellneed streamlined
- display Stop in .CURDIR after an error.

|
|
- 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.
|
|
|
|
Support SVR4 style archives.
Fix pr/1421 (from Matthew Green) and pr/1997 (from Jeff Thieleke).
In ParseDoInclude(), make a temporary copy of the current file name
while searching for ""-type include files, since the current file name
might not be a writeable string.
