Re: [naviserver-devel] Naviserver hangs on Windows

[Maurizio M. <Mau...@sp...>]

The Windows-OpenACS distribution which I make available here
(http://www.spazioit.com/pages_en/sol_inf_en/windows-openacs_en/) is based
on AOLServer 4.5.2, contains the sources, is compiled with Visual Studio
2013 and runs on Windows 64.
So if I where you I would give a look at that distribution and see how all
those time related functions have been handled.
That could save you some time.

Subject: Re: [naviserver-devel] Naviserver hangs on Windows

Hm, the old AOLserver 4.0.7 version of Ns_GetTime() had a Windows ifdef
which is entirely missing from Naviserver!  (See below.)

I found two relevant commits in Mercurial, from 2009 and 2012, below.
>From those logs, it looks like what happened is that in 2009, Zoran
removed the platform specific C code and instead made Naviserver call
Tcl_GetTime (somehow).  Then in 2012, Gustaf added back the old
Unix-specific gettimeofday() implementation for performance reasons.

So should we just add back the old Windows-specific C implementation too?
Or is it better to use Zoran's way of invoking Tcl_GetTime?  Do we even know
for sure if that method really is "platform-independent"
as Zoran thought it was?  E.g., did Zoran or someone else at Archiware test
it on Windows?


Part of Ns_GetTime() from ancient AOLserver 4.0.7 sources:
------------------------------------------------------------
#ifdef _WIN32
/*
 * Number of 100 nanosecond units from 1/1/1601 to 1/1/1970  */ #define
EPOCH_BIAS  116444736000000000i64
    union {
	unsigned __int64    i;
	FILETIME	    s;
    } ft;

    GetSystemTimeAsFileTime(&ft.s);
    timePtr->sec = (time_t)((ft.i - EPOCH_BIAS) / 10000000i64);
    timePtr->usec =(long)((ft.i / 10i64) % 1000000i64); #else #endif
