Saves having to malloc/free a fixed size structure.
Buf_Init() now takes ptr to Buffer to initialiase.
Change Buf_Destroy() to return ptr to string when not freed.
Remove large number of casts to (Byte) and (Byte *) - 'Byte' is 'char' here.
Buf_AddByte[s] guarantees that the data is 0 termininated, so never add '\0'.
Keep 'count' not 'left' and 'inPtr', code is simplier with only one update.
Fix fallou, no functional change.
bmake_malloc and friends. Implement them via macros for the native case
and provide fallback implementations otherwise. Avoid polluting the
namespace by not defining enomem globally. Don't bother to provide
strdup and strndup, they were only used for the estrdup and estrndup
comapt code.
This addresses the presence of emalloc in system libraries on A/UX and
resulted strange issues as reported by Timothy E. Larson.
Instead of adding MAKE_BOOTSTRAP for hosted environments, i.e., when
you want things simple, instead add MAKE_NATIVE to get those hugely
important features like __RCSID().
It's now possible to build make on some hosts with: cc *.c */*.c
Also :tW and a W flag to :C and :S to allow treating value as a single word.
Add unit tests for the above, and fix some corner cases.
Based on patches supplied by Alan Barrett <apb@cequrux.com>
Unfortunately this revealed a deeper problem with the brk_string code.
To fix it:
- remove sharing of the buffer between brk_string invocations
- change the semantics of brk_string so that the argument array
starts with 0, and return the buffer where the strings are
stored
var.c: Minor memory leak plugged.
suff.c: Don't add extra sources on the null suffix if it has dependency
lines or commands attached to it [POSIX says so]
The following two patches fix a couple of problems with make(1)
1. Null Suffixes were not being copied, but they were being free'd
This caused rules of the form:
.c:
${CC} ...
to access invalid memory and potentially core dump..
[That was always broken; I did not break that one :-)]
2. My recent fixes to parse ${VAR:%.foo=%.bar} handled the null string
case incorrectly (${VAR:=.c} was broken).
