Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.
GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH
Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.
Add more error handling to pax -r -w so that any failure
during the copy to the temporary file (including a failed flush)
prevents any existing destination file from being replaced
with the partial (including possibly empty) temporary file.
The partial temporary file is removed. pax still exists non-zero.
Thanks to Michael van Elst (mlelstv@) for the analysis
of the problem in the PR.
Should fix PR misc/33753.
If copying a list of files from stdin, exit zero instead of non-zero
if there are no files supplied.
AFAICT, POSIX doesn't require a non-zero an error in this situation,
since there are no files to not match.
Fix from PR bin/41736 by Lloyd Parkes.
GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)
use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.
we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."
Stamp out "greengrocers' apostrophes" in various places (arguably there
are still more present, but style guides vary on that, and my energies
spent corralling wayward punctuation marks could be spent elsewhere).
As a somewhat pedantic clarification, "-s" does not accept backslashes
as delimiters. (While here, also make the macro use of an expression
shared between pax.1 and tar.1 consistent.)
Note the "s" option has an "s" flag that "prevents substitutions from
being performed on symbolic link destinations". Carry over r. 1.25 from
christos@ and part of r. 1.26 from wiz@ from tar.1, since this
functionality is available in pax as well as tar.
buffer. If snprintf truncated the output, the length returned will be
greater and we'll write trash. Just call strlen instead. (And since
what we're doing is writing progress messages to the user, checking
carefully for truncation isn't really worthwhile either.)
Spotted when attending to PR 50998 from David Binderman; the issue
there (computation of an unused value) popped up because one of the
prints was already calling strlen.
erroneously think that negative time_t's never fit in 32 bits. Rework
conversion code to always use uintmax_t, and detect negative values.
XXX[1]: Perhaps we should do the same (use a signed conversion) for all
fields not just for time_t
XXX[2]: pullup for 6
