Bug ID: 39988 Summary: winepath -w wrong output with path longer 260 Product: Wine Version: 1.9.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: s3141p@gmail.com Distribution: ---
When the input $pathname is longer than 260 characters wine -w $pathname 1. truncates the converted output path at 260 characters 2. appends some garbage characters to it 3. reports no error and exits with status 0
I think fixing #3 as a minimum is important; at least exit 1, possibly print an error message.
Fixing #2? Why is it printing garbage characters? Buffer overrun?
And please consider changing #1 by extending support to paths > 260 characters. After all, if I convert the same path by hand and feed it to a Windows application it has no problems dealing with it. So the 260-character limit of winepath -w seems rather artificial to me.
I create long linux paths with mkdir -p /tmp/aaa/bbb/ccc/ddd/eee/ touch /tmp/aaa/bbb/ccc/ddd/eee/$(dd if=/dev/zero count=1 bs=260 | tr '\000' a) # which creates /tmp/aaa/bbb/ccc/ddd/eee/aaaaaaaa...
Thanks.
