* update the editor hints for spaces, not tabsRicardo Signes2012-05-291-2/+2
| | | | | This updates the editor hints in our files for Emacs and vim to request that tabs be inserted as spaces.
* Add :not_characters parameter to 'use locale'Karl Williamson2012-01-211-2/+2
| | | | | This adds the parameter handling, tests, and documentation for this new feature which allows locale and Unicode to play well with each other.
* diag_listed_as galoreFather Chrysostomos2011-12-281-0/+3
| | | | | In two instances, I actually modified to code to avoid %s for a constant string, as it should be faster that way.
* Add flag to num groks to silence non-portable warningsKarl Williamson2011-07-031-3/+18
| | | | | | | Unicode inversion lists commonly will contain UV_MAX, which may trigger these warnings. Add a flag to suppress them to the numeric grok functions, which can be set by the code that is dealing with these lists
* [perl #32380] numeric.c assumes that NV_DIG+2 will be enough digitsEd Allen Smith2010-10-031-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for all precision possible in NV numeric.c, in the Perl_my_atof2 function, makes the following assumption: /* There is no point in processing more significant digits * than the NV can hold. Note that NV_DIG is a lower-bound value, * while we need an upper-bound value. We add 2 to account for this; * since it will have been conservative on both the first and last digit. * For example a 32-bit mantissa with an exponent of 4 would have * exact values in the set * 4 * 8 * .. * 17179869172 * 17179869176 * 17179869180 * * where for the purposes of calculating NV_DIG we would have to discount * both the first and last digit, since neither can hold all values from * 0..9; but for calculating the value we must examine those two digits. */ #define MAX_SIG_DIGITS (NV_DIG+2) Digits beyond MAX_SIG_DIGITS are ignored. In some systems and/or modes (e.g., with/without using long doubles), this is not the case. One example is IRIX when using long doubles, which are not fully IEEE compliant; with it, while NV_DIG (the _minimum_ number of digits usable) is 31 for long doubles used as NVs, long doubles can have up to 34 digits of accuracy. (As well as IRIX with long doubles, other machines using a mode in which NV is not IEEE compliant (e.g., as found by the following from numeric.c: #ifdef ((defined(VMS) && !defined(__IEEE_FP)) || defined(_UNICOS)) (although UNICOS does not by default use Perl's atof in any event) or as noted in the hints files for DEC OSF with the old MIPS CC) may benefit from a change to this.) I will attach a test program, example set of problematic outputs, and experimental patch so others can explore this on their systems. (With the patch and a -Accflags='-DMAX_SIG_DIG_PLUS=3' (or -Accflags='-DMAX_SIG_DIG_PLUS=4'), the test program was successful. Different values of MAX_SIG_DIG_PLUS may need to be experimented with, especially with different other Configure/compiler flags (long doubles yes/no, optimization affecting floating point, etcetera); 3 was the maximum that did any good on IRIX with long doubles, but others may differ.) I have done some local testing (as in the normal testsuite) of the patch and different -DMAX_SIG_DIG_PLUS values, and will be doing more; it is possible that it would be best to build in the test program into, say, numconvert.t. Patching hints/irix_6.sh to use -DMAX_SIG_DIG_PLUS=3 if long doubles are in use, or a define of MAX_SIG_DIG_PLUS to 3 if defined(IRIX) and long doubles are in use, is also advisable; I have not included either in my patch because I was unsure which was recommended practice.

* use cBOOL for bool castsDavid Mitchell2010-04-151-3/+3
| | | | | | | | | | | | | bool b = (bool)some_int doesn't necessarily do what you think. In some builds, bool is defined as char, and that cast's behaviour is thus undefined. So this line in mg.c: const bool was_temp = (bool)SvTEMP(sv); was actually setting was_temp to false even when the SVs_TEMP flag was set. Fix this by replacing all the (bool) casts with a new cBOOL() cast macro that (hopefully) does the right thing.
* Add Perl_ck_warner_d(), which combines Perl_ckwarn_d() and Perl_warner().Nicholas Clark2009-10-121-9/+6
| | | | | Replace ckWARN_d{,2,3,4}() && Perl_warner() with it, which trades reduced code size for 1 more function call if warnings are not enabled.
* Add Perl_ck_warner(), which combines Perl_ckwarn() and Perl_warner().Nicholas Clark2009-10-121-17/+14
| | | | | | | Replace ckWARN{,2,3,4}() && Perl_warner() with it, which trades reduced code size (about 0.2%), for 1 more function call if warnings are not enabled. However, if we're now in the L1 or L2 cache when we weren't previously, that's still going to be a speed win.

We've already done this at least twice. (Yes, some of the assertions are after code that would already have SEGVd because it already deferences a pointer, but they are put in to make it easier to automate checking that each and every case is covered.)
