Re: differ file in SVN checkout and export

Hello, yes, we can remove 'svn:special' property on binary file, and commit will fine. And sorry i don't understand you phrase "did not remove the svn:special property at the same time"

Also I don't understand what had changed in svn export command since 1.10 version, that the old version return correct binary file but new version return the file that different from the original ?

Can you explane me please?

Thank you

We got difference in the same revision and same file but taken by export and checkout in SVN client version more or equal than 1.10:

$ svn co https://svn-test.net/svn/test/ -r9 checkout
Checked out revision 9.
$ svn export https://svn-test.net/svn/test/ -r9 export
A export
A export/EmptyStandbyList.exe
Exported revision 9.
$ diff checkout/EmptyStandbyList.exe export/EmptyStandbyList.exe

$ md5sum export/EmptyStandbyList.exe

$ md5sum checkout/EmptyStandbyList.exe
10ab6937e720856efd4a315f0f06fcfb checkout/EmptyStandbyList.exe

no difference as we see

$ svn --version
svn, version 1.9.7 (r1800392)
compiled Mar 28 2018, 08:49:13 on x86_64-pc-linux-gnu
$ cd checkout/
$ svn proplist EmptyStandbyList.exe -v
Properties on 'EmptyStandbyList.exe':
svn:special

Try removing the 'svn:special' property; it shouldn't be set on normal files.

Now we repeat on other version of client:

$ svn --version
svn, version 1.11.1 (r1850623)
compiled Jun 17 2019, 17:51:58 on x86_64-pc-linux-gnu
$ svn co https://svn-test.net/svn/test/ -r9 checkout
$ svn export https://svn-test.net/svn/test/ -r9 export
$ diff checkout/EmptyStandbyList.exe export/EmptyStandbyList.exe
Binary files checkout/EmptyStandbyList.exe and export/EmptyStandbyList.exe differ

$ md5sum export/EmptyStandbyList.exe
5ddd018068333a4fa03e08b5451b1d52 export/EmptyStandbyList.exe

Please also look at the size of the file and the contents.

$ md5sum checkout/EmptyStandbyList.exe
10ab6937e720856efd4a315f0f06fcfb checkout/EmptyStandbyList.exe

$ cd checkout/
$ svn proplist EmptyStandbyList.exe -v
Properties on 'EmptyStandbyList.exe':
svn:special
*

( also we repeated tests on different client versions and systems with the same result)

How we simulate situation:
1) we made a link to file in linux system
$ ln -s ../EmptyStandbyList.exe EmptyStandbyList.exe
$ ll
EmptyStandbyList.exe -> ../EmptyStandbyList.exe
2) commit this
$ svn add EmptyStandbyList.exe
$ svn commit -m "add link"
3) in windows client Tortoise we just replaced link by actual binary file and committed again

... and did not remove the svn:special property at the same time.

Maybe Subversion should just error out when it sees that the contents of a "symlink" changed in a way that it clearly is no longer a valid link description?
