Hi All
I found interesting thing with diff command, I have compiled diff with 64-bit to support large files (> 2GB) and it is working fine without using -a option. When I use -a option on large files I am getting below error. Posted a question to diff command group as well, but no response. Error Message: diff: memory exhausted '-a' option used to "Treat all files as text and compare them line-by-line, even if they do not seem to be text". We have built RCS with GNU diff utility and with '-n' and '-a' options for diff, so check-in is failing for large files. Here I have doubt whether RCS will work without '-a' option or not. Can anyone tell me if you already tried without '-a' option. My server architecture is : SunOS hostname 5.9 Generic_122300-47 sun4u sparc SUNW,Ultra-4 Thank you in Advance! --Sudhakar -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Peram, Sudhakara Sent: Thursday, January 13, 2011 2:31 PM To: Hugh Sasse Cc: [email protected] Subject: RE: ci failed for large files (>2GB) - diff: memory exhausted Thanks Hugh for your response! Yeah I know that RCS will not be able to produce the differences (i.e., rcsdiff) between two versions of binary file. As per my understanding ci will use the diff command to check whether the latest file and the last version of that file are being same or different before check-in. And for the file less than 1GB it is working fine. I have tried to check-in the file with 5.5GB and it worked fine for the initial revision. Let me see if someone can help me in this regard. --Sudhakar -----Original Message----- From: Hugh Sasse [mailto:[email protected]] Sent: Thursday, January 13, 2011 2:15 PM To: Peram, Sudhakara Cc: [email protected] Subject: RE: ci failed for large files (>2GB) - diff: memory exhausted i can't remember for certain, but I am pretty sure that RCS does not support binary files. I think the newer systems like git will handle this sort of thing, but it seems that differences are not really done for binary files, at least going by casual observation of the size and description of changes. If you need the compression afforded by differences for binary files, then I'm not able to make any suggestions. Hopefully someone else who knows more can respond.
