So, to answer my own questions ... I placed the code below in a
taskpool parallel foreach loop, where each am is an archive
member. It is expanded, and the expanded data is written to a
file. The original time info is coverted to SysTime using a
localTime() tz timezone calculated outside the loop. Then the
setTimes call updates the file timestamp in Windows. I just used
the same system time st value for modification and access times.
expand2(am);
string destFilename = destName ~ am.name;
std.file.write(destFilename,am.expandedData);
SysTime st = DosFileTimeToSysTime(am.time, tz);
std.file.setTimes(destFilename, st, st);
The whole unzip, including restore of file modification times,
completed in under 17 seconds for this 2GB expanded directory
structure with some 39K files. 7zip took 55 seconds.
This particular loop is currently excluding restore of times on
directory entries, but I suppose I can restore the directory
times after all the files have been expanded into the directory
structure.
great idea if its ok that the directory strucutre is in an inconsistent
state on error - thats the main problem with parallel stuff - its faster
if everything works ok - its hard to control the state if not
