rillig | bin: fix lint warning "effectively discards 'const'"
For example: src/bin/ed/io.c(339): warning: call to 'strchr' effectively
discards 'const' from argument [346]
No binary change.

kre | The great shell trailing whitespace cleanup of 2023...
Inspired by private e-mail comments from mouse@
NFCI.
|
| 1.40 |
| 21-Nov-2017 |
kre | branches: 1.40.4;
Remove the -X option from SMALL shells (as used on boot floppies,
some other install media, mini-roots, etc.) It is unlikely that
such a shell will be used for much script debugging (and the old -x
still exists of course) and it adds a little bloat, so, zap...
The ancient unused (unrelated) xioctl() function is gone as well
(from all shells).

kre | Implement the -X option - an apparent variant of -x which sends all trace
output to the stderr which existed when the -X option was (last) enabled.
It also enables tracing by enabling -x (and when reset, +X, also resets
the 'x' flag (+x)). Note that it is still -x/+x which actually
enables/disables the trace output. Hence "apparent variant" - what -X
actually does (aside from setting -x) is just to lock the trace output,
rather than having it follow wherever stderr is later redirected.

| 19-Nov-2017 |
kre | Rearrange "struct output" to be slightly more friendly (I think)
to I32 P64 systems - keep nextc first, as that's used in macros,
and nleft next, as that's used (and both are updated) in the same macro,
which is used frequently, this increases the chance they're in the
same cache line (unchanged from before). Beyond that it matters less,
so just shuffle a bit to avoid internal padding when pointers are 64 bits.
Note that there are just 3 of these structs (currently), even if there was
to be a memory saving (there probably won't be, trailing padding will eat it)
it would be of the order of 12 or 24 bytes total, so all this really
just panders to my sense of rightness....
Note to anyone who might be tempted, please don't update the struct
initializers to use newer C forms - eventually sh is planned to become
a host tool, and a separable package, so it wants to remain able to be
compiled using older (though at least ansi) compilers that implement only
older C variants.

kre | Improve quoting in xtrace (-x) output ... if a string ("word") to be
output includes a single quote (') then see if using double-quotes
to quote it is reasonable (if no chars that are magic in " also appear).
If so, and if the string is not entirely the ' character, then
use " quoting. This avoids some ugly looking results (occasionally).
Also, fix a bug introduced about 20 months ago where null strings
in xtrace output are dropped, instead of made explicit ('').
To observe this, before you get the fix: set -x; echo '' (or similar.)
Move a comment from the wrong place to the right place.

kre | branches: 1.36.2;
Added comma and plus to the "don't need quoting" set. This affects
output from "sh -x" only (tracing execution), not quoting + is better,
as it makes tracing commands with + and - options, or numbers, more
consistent.
Also one minor white space change (excess indentation removed).
|
| 1.35 |
| 12-Mar-2016 |
christos | branches: 1.35.6;
Improve quoting in the output from sh -x - use less unnecessary
quotes ('_' and '.' do not need quoting) and never quote the '=' in
an assignment (or it would not be one.) From kre, with some refactoring
to be blamed to me.
|
| 1.34 |

| 24-Nov-2002 |
christos | Fixes from David Laight:
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
(so I could unset -e PS1 before running the test shell...)

unnecessary #else cases).

thorpej | Move the declaration of digit[] into the #ifdef'd code block that

wiz | va_{start,end} audit:
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).
Improved by comments from enami and christos -- thanks!
Heimdal/krb4/KAME changes already fed back, rest to follow.
Inspired by, but not not based on, OpenBSD.
