CVS2GIT - Is there a limit on individual file size ?

[Kenneth M. Lee]

Hi -

Thanks for cvws2git !

Is there a known limit on the size of an individual file ?

I have a ZIP file that is around 225MB and when we convert our code base, it is converted, but only to a file whose size is ~8K.

Thank you !

The only limit should be the amount of address space available to the
conversion script. Considering temporary copies and other stuff that is
held in RAM, I would think that some fraction (say 1/4) of the available
address space should usually not present any problems.

On a 32-bit computer, the available address space is at most 2 - 4 GiB.
On a 64-bit computer, is is something like the total amount of (RAM
plus swap space).

For a modern computer I wouldn't expect a problem with a file of this
size. And if there were a problem due to the size of the file, I would
expect an out-of-memory error. I certainly wouldn't expect the file to
be truncated silently.

1. Are you using the trunk version of cvs2git? (I recommend it.)

2. Did you check the output of the script carefully for errors? (Maybe
try running it in verbose mode.)

3. Is the dumpfile that is output by cvs2git the size that you would
expect? (If so, the problem might be in "git fast-import".)

If you still can't figure out the problem, we will need more information
to help you. Please read the FAQ for instructions on how to report a
problem.
