Import the latest bsd-features branch of the one-true-awk upstream: o Move to bison for $YACC o Set close-on-exec flag for file and pipe redirects that aren't std* o lots of little fixes to modernize ocde base o free sval member before setting it o fix a bug where a{0,3} could match aaaa o pull in systime and strftime from NetBSD awk o pull in fixes from {Net,Free,Open}BSD (normalized our code with them) o add BSD extensions and, or, xor, compl, lsheift, rshift (mostly a nop) Also revert a few of the trivial FreeBSD changes that were done slightly differently in the upstreaming process. Also, our PR database may have been mined by upstream for these fixes, and Mikolaj Golub may deserve credit for some of the fixes in this update.

With scalpel, tweasers, magnifying glass and bated breath,
|
|
borrow code from the NetBSD version of nawk to fix the years-old
|
|
bug whereby decrementing the value of NF did not change the
|
|
record.
|
|
|
|
* lib.c (fldbld): Set donerec to 1 when done.
|
|
(setlastfld): New function.
|

* run.c (copycell): Make code smarter about flags (from NetBSD code).
|
|
* tran.c (setfree): New function.
|
|
* tran.c (setfval): Normalize negative zero to positive zero.
|
|
If setting NF, clear donerec and call setlastfld().
|
|
(setsval): Remove call to save_old_OFS(). If setting OFS, call
|
|
recbld(). If setting NF, clear donerec and call setlastfld().
|
|
|
|
As part of the process, revert OFS-related changes of 2018-05-22:
|
|
|
|
* awk.h (saveOFS, saveOFSlen, save_old_OFS): Remove declarations.
|
|
* lib.c (recbld): Use *OFS instead of saveOFS.

|
to NF or OFS, but fixes a compiler complaint.)
