strftime() and strptime() indirect via System.TM?
by Stephen R. van den Berg 15 Jan '18

15 Jan '18

While adding strftime() and strptime() methods to Val.Timestamp and Val.Date, I couldn't help but noticing that in order to access both libc functions I need to go through System.TM. Wouldn't it be preferable to create direct native builtins for those two functions instead? (to put them in the same boat with mktime/gmtime etc?) -- Stephen.

AmigaOS... and Pike 8.1
by Stephen R. van den Berg 12 Jan '18

12 Jan '18

I just ripped out AmigaOS from Pike 8.1. Martin warned me (after I'd already ripped it out, of course) that maybe Marcus is still using it? So, is anyone still using AmigaOS in Pike 8.1? If yes, I'll revert the patch. If no, or if we stop supporting at 8.1, I'll leave it as is. -- Stephen.

GTK/GDK on OSX
by H William Wellliver III 08 Jan '18

08 Jan '18

I’m running into some build problems on OSX. It seems that the GTK module assumes that if a system is NT that gdkwin.h is used and otherwise gdkx.h is used. Unfortunately, it seems that on some builds of GTK/GDK for OS X, neither of those is correct and that gdkquartz.h should be used. I’m guessing that some configure tests are needed to determine which of the 3 files is actually present. However a quick look at configure.in leaves me unsure how best to include that. Anyone with more expertise in the GTK module’s inner workings care to weigh in? Bill

There are a few regressions when running verify with dmalloc, if anyone has the time to take a look.

Port fixes to mktime() and System.TM() from 8.1 to 8.0?
by Stephen R. van den Berg 26 Dec '17

26 Dec '17

As a by-product of creating the Val.Timestamp (et al) types, I encountered numerous bugs and uncertainties in mktime() and System.TM() with regard to timezone handling/abuse. AFAICS, all these bugs have now been dealt with and fixed in 8.1. Any objections if I port these fixes from 8.1 to 8.0? It, incidentally, would allow us to git rid of some slow/undeterministic custom Pike-mktime() code (so the Pike footprint gets smaller, faster and deterministic with the fixes applied). -- Stephen.

Problem on SunOS 5.10 I cannot figure out
by Stephen R. van den Berg 24 Dec '17

24 Dec '17

Xenofarm machine: motoko.roxen.com (maybe others too) Git pike 8.1 Case in point: In the testsuite I created two entries: test_eq(mktime (33, 3, 12, 14, 6, 117, 0, 0), 1500033813); test_eq(mktime ((["sec":33, "min":3, "hour":12, "mday":14, "mon":6, "year":117, "timezone":0])), 1500033813); They should be equivalent. And they are (on other machines), but on this machine, they differ because of this code segment in src/builtin_functions.c (code shortened for readability, irrelevant parts omitted): ------------------------------------------ PMOD_EXPORT void f_mktime (INT32 args) { if(args == 1) { push_static_text("sec"); push_static_text("min"); push_static_text("hour"); push_static_text("mday"); push_static_text("mon"); push_static_text("year"); push_static_text("isdst"); push_static_text("timezone"); f_aggregate(8); f_rows(2); Pike_sp--; dmalloc_touch_svalue(Pike_sp); push_array_items(Pike_sp->u.array); args=8; } get_all_args("mktime",args, "%i%i%i%i%i%i.%i%i", &sec, &min, &hour, &mday, &mon, &year, &isdst, &tz); if((args > 7) && (SUBTYPEOF(Pike_sp[7-args]) == NUMBER_NUMBER)) { ------------------------------------------ It appears that when mktime() is called using 8 direct arguments, it works fine and (SUBTYPEOF(Pike_sp[7-args]) == NUMBER_NUMBER evaluates to true. However, if mktime() is called using a mapping as sole argument, it works fine on most machines, but on motoko/SunOS 5.1 then (SUBTYPEOF(Pike_sp[7-args]) == NUMBER_NUMBER evaluates to false? Any clues? I want to avoid debugging this through successive approximation and xenofarm. NUMBER_NUMBER seems to be defined to 0, BTW. -- Stephen.

If they can share common code, it might be good to have them in one module, with encode_json5 and decode_json5. AIUI, if you're not sure which one you're decoding, you can decode as JSON5, as it's a strict superset of JSON. ChrisA

GTK2.Object()->destroy() checking for no args?
by Chris Angelico 24 Dec '17

24 Dec '17

I doubt anyone will know the answer to this, as it's in 12+ year old code in the GTK2 module, but the destroy method (now renamed to _destruct) was explicitly checking that it received exactly zero args before calling gtk_object_destroy. Any idea why? Is there a situation in which destroy() might have been called with arguments, such that it shouldn't actually destroy anything? I've removed the check, and now GTK2 apps correctly clean up their underlying objects when they're destroyed. But I'm hoping this hasn't reintroduced an old problem somewhere. ChrisA
