Hi,
Is there any special support for sparse file handling in python? My
initial search didn't bring up much (not a thorough search). I wrote
the following pice of code:
options.size = 6442450944
options.ranges = ["4096,1024","30000,314572800"]
fd = open("testfile", "w")
fd.seek(options.size-1)
fd.write("a")
for drange in options.ranges:
off = int(drange.split(",")[0])
len = int(drange.split(",")[1])
print "off =", off, " len =", len
fd.seek(off)
for x in range(len):
fd.write("a")
fd.close()
This piece of code takes very long time and in fact I had to kill it as
the linux system started doing lot of swapping. Am I doing something
wrong here? Is there a better way to create/modify sparse files?
Thanks,
Raghu.
