Re: wish: string with other quoting then \

Of course, #" should still support \ as an escape character because doing otherwise would break backwards compatibility. Other #*:s should not though. Makes it slightly unorthogonal, I'm afraid...

Win32 SMP

7.4.28 have a problem with Win32 and multiple processors. I'm going to try (again) to make a binary search for when the problem was introduced, but if someone has any ideas feel free to share. This is where it breaks when trying to run the installer: http://peter.bortas.org/pikedev/smpcrash.JPG

Is there any reason why svalue/int/float sizes are omitted in configinfo.txt which appears on pikefarm? Regards, /Al

I've done a bit of testing myself. The figures one gets depend a lot on the kind of testing, but this is a fairly straightforward case when searching for a submatch that doesn't exist in a large string: Pike: 0.00017900 s Perl: 0.00074000 s Emacs 20: 0.04566600 s Emacs 21: 0.05563044 s TRE: 0.07000000 s GNU Regex: 0.16000000 s The shortcoming in Pikes Regexp is the lack of features, not the speed. / Martin Stjernholm, Roxen IS Previous text: >2003-09-19 15:30: >Subject: Re: Adding PCRE to Pike >-------------------------------------------------------------------- >where did you see that? > >greetings, martin. > > > / Brevbäraren >

Adding PCRE to Pike
by Martin Stjernholm, Roxen IS ＠ Pike developers forum 19 Sep '03

Open question: What problems are there to add PCRE to Pike? Sure it'd be nice to have a regexp package that groks wide strings but since Regexp isn't better in that regard there's nothing to lose.

time() and optimization again
by Alexander Demenshin 19 Sep '03

19 Sep '03

Hi, Long time ago I posted a message about wrong optimization with time() (and perhaps something else). Nobody replied, and the problem is still present in recent CVS (7.4.27). So here it is again: --- snip --- Just found another bug(?) - the construction like: int ts = time() + 10; while (time() < ts) /* nothing */ ; is wrongly optimized - it doesn't work as expected, i.e. the loop is bypassed - so virtually there is no delay. When I change it to 'while ((n = time()) < ts);' or put something in body, it works. Checked against one day old CVS Pike 7.4 (7.4.17). NB: Is it related to time() only or? :) --- snip --- Also, there is a (slight) inconvenience with time() function. To retrieve current time with high precision I've to use time(2)+2.0, since only this syntax allow to retrieve time with microsecond precision. But, unfortunately, it adds 2 seconds to the result. Sure, extra float op is nothing (almost), but at least inconvenient and misleading. Would it be a good idea to add an extra option (say, negative argument) to return current time as float without using base (which is the case when argument is > 1)? And last about time() :) When Pike is compiled with default float size, its float result is absolutely unrealiable (even wrong) - because of very limited precision (just try: time() - (int)(time(2)+2), the difference will impress you). Yes, I know that there is gethrtime() etc., but I can't use it (directly) with call_out(), for instance (and gethrtime() involves MPI, which is quite slow comparing to floats, even double precision floats).

float type weirdness
by Alexander Demenshin 19 Sep '03

19 Sep '03

Hi, I was surprised that float type is somewhat "special", like here: float x = 0.0; // OK, I can live with the fact that I just can't assign "0" :) // However, it would be convenient to make an exception for this // special case (zero) if (!x) something(); // Will be never called, since x is _always_ true // while it is (numerically) is zero (7.4.20) Is this intentional? According to the tutorial: "When Pike encounters an if statement, it first calculates the value of the expression. Pike then checks if this value is true or false. The value zero (0) is considered to be false, and everything else is true." It is not mantioned that "zero" has to be integer zero, and everywhere else (C, Perl etc) float zero is false.
