35eca590ad Tell xgettext that "ARG1 % ARG2" is not a C format string. 
* src/expr.c (usage): Add a comment to override xgettext's default
behavior, which would classify "ARG1 % ARG2" as a fprintf-style
format string.

4e2fd4cca6 Avoid a leak in expr's implementation of the ":" (match) operator. 
* src/expr.c (docolon): Free the regexp buffer using regfree, rather
than doing it manually, being careful to set fastmap to NULL first.
Free any re_regs.start and .end members, if necessary.

d28b0d4de8 (eval6): Fix buffer overrun, or bad performance, if 
substr's last operand is very large.  Performance problem reported
by Sebastian Kreft.
 2006-09-11 04:56:43 +00:00
Paul Eggert
cad27cdc2e (eval4): Detect overflow properly when multiplying INTMAX_MIN * -1. 2006-06-08 02:53:25 +00:00

0eef2e1e8b Don't claim x86 behavior is erroneous in a comment. 2006-06-07 05:58:57 +00:00
Paul Eggert
dea306fe78 (integer_overflow): New function. 
(eval4, eval3): Check for integer overflow.
 2006-06-07 05:52:27 +00:00
Paul Eggert
7e17831f0a Clear the RE_NO_EMPTY_RANGES re syntax option, as this is a less intrusive 
change from the old (Emacs) behavior, and POSIX allows us to treat [z-a]
as an empty range.
 2006-04-12 07:37:11 +00:00
Paul Eggert
110970f622 (docolon): Set re_syntax_options to a value that is compatible with 
what POSIX requires.  Also, don't let anchors match
newline; this fixes an incompatibility with tradition and with POSIX.
Don't warn about leading ^.  POSIX says it is unspecified whether
^ is a special character, which means that implementations can
either treat it as special or not, but either way a warning is not
allowed (unless the regexp is otherwise invalid).  Instead, anchor
the expression but treat ^ as an anchor; this is the traditional
behavior (e.g., Solaris 10).
(eval4, eval3, eval2): Treat non-numeric args, division by zero,
and the like as invalid expressions (exit status 2), not as
failure of 'expr' (exit status 3).  This is more consistent with
how Solaris behaves.

Paul Eggert
2a124564c7 (docolon): Allocate and use a fastmap. 
Don't bother allocating a buffer.

f682977c0c whoops: Adding quote(...) isn't enough :) 
remove quotes from the string, too.
 2005-06-16 21:41:57 +00:00
Jim Meyering
f696c57a8e Don't embed `this'-style quotes in format strings. 
Include "quote.h".
Rather than this: error (..., "...`%s'...", arg);
do this:          error (..., "...%s...", quote (arg));
 2005-06-16 21:37:37 +00:00
Paul Eggert
6d740fd9ee Include strnumcmp.h, xstrtol.h. 
(looks_like_integer): New function.
(toarith): Use it.  Also, use xstrtoimax rather than rolling our
own diagnostics.
(eval2): Don't look for trouble if !evaluate; this simplifies things.
Compare numbers using string comparison, so that overflow is
not possible.

f83e17f928 (tostring, printv): Use INT_BUFSIZE_BOUND in place of INT_STRLEN_BOUND + 1. 2005-03-10 08:02:24 +00:00
Jim Meyering
7eff5901c4 (toarith): Rewrite to detect/diagnose integer overflow, 
rather than suffering silently.
Before, expr would silently overflow and wrap around:
  $ expr 9223372036854775808 = 0   # $(echo 2^63|bc)
  1
Now it detects the problem and exits nonzero:
  $ ./expr $(echo 2^63|bc) = 0
  ./expr: 9223372036854775808: integer is too large
 2005-01-14 14:15:25 +00:00
Paul Eggert

reference to obsolescent macro XMALLOC.
All uses replaced by xmalloc and free.

ae631658b0 (nextarg): Use bool for booleans. 2004-08-03 06:00:24 +00:00
Jim Meyering
1ce7b61d0e (main): Standardize on the diagnostics given when someone gives 
too few operands ("missing operand after `xxx'") or
too many operands ("extra operand `xxx'").
Include "quote.h" and/or "error.h" if it wasn't already being included.
 2004-06-21 15:03:35 +00:00
Jim Meyering
3c3e1584ed (nextarg): Prefer the notation STREQ (a, b)' over strcmp (a, b) == 0'. 2004-06-01 12:52:14 +00:00
Jim Meyering
fdb3c26e8e (eval, eval7, eval6, eval5, eval4, eval3, eval2, eval1): 
Accept a bool argument specifying whether to evaluate the
expression.  This is to allow short-circuit evaluation.  All
callers changed.
(null): Report that a string is zero even if it has
a form like "-0" or "00".
(eval1, eval): Use short-circuit evaluation for | and &.
(eval): Return 0 if both arguments are null or zero, instead
of returning the first argument.
 2004-02-22 14:56:58 +00:00
Jim Meyering
c2c0e244df (usage): Use EXIT_SUCCESS, not 0, for clarity. 
(main): Use initialize_exit_failure rather than
setting exit_failure directly; this optimizes away redundant assignments.
(EXPR_FAILURE): Renamed from EXPR_ERROR, for
consistency with the other programs' naming conventions.
All uses changed.

df81ab2911 Cast NULL to `(char *)' in call to variadic function, 
parse_long_options, so that it works even on systems for which
sizeof char* != sizeof int.
 2003-11-05 03:53:19 +00:00
Jim Meyering
cf4fdf373f Most .c files (AUTHORS): Revert the WRITTEN_BY/AUTHORS change 
of 2003-09-19.  Now, AUTHORS is a comma-separated list of strings.
Update the call to parse_long_options so that `AUTHORS, NULL' are the
last parameters.

* src/true.c (main): Append NULL to version_etc argument list.
* src/sys2.h (case_GETOPT_VERSION_CHAR): Likewise.
 2003-10-18 10:05:47 +00:00
Jim Meyering
bafd927f03 (WRITTEN_BY): Rename from AUTHORS.

1eaf0e9870 Include "exitfail.h", "quotearg.h". 
(EXPR_INVALID, EXPR_ERROR): New constants.
(nomoreargs, null, toarith, nextarg): Return bool, not int.
(syntax_error): New function, exiting with status 2.  Use it
insteading of printing "syntax error" ourselves.
(main): Initialize exit_failure to EXPR_ERROR.
Exit with EXPR_INVALID on syntax error (too few arguments).
(nextarg): Use strcmp, not strcoll; strcoll might return
an undesirable 0, or might fail.
(docolon, eval4, eval3): Exit with status 3 on invalid argument type
or other such error.
(eval2): Report an error if strcoll fails in a string comparison.

3ca688d69a Don't include "xalloc.h", as system.h already does that via sys2.h. 2002-01-21 19:53:23 +00:00
