synchronize a directory junction not working since 5.x

Script-synchronizing a local directory that contains a junction to another
directory (also local not network) to remote does not work since 5.x

tried: 5.1.7, 5.5.6, new 5.7.6
4.3.6 is working.

for version 5.x it is working, if at the remote (!) side the directory is created before

OS: Windows Server 2003 (with sysinternals tool junction.exe) .
On a Win7 HomePremium with std. tool mklink /J I cannot reproduce.

Using: SFTP, remote: Linux debian

found similar error in forum: forum/viewtopic.php?t=13461

Attached logfiles:
D:\ECGData\Muse.xmlout is the junction that fails.


Full script:
winscp.exe /console /ini=winscp.ini /log=xx.log /xmllog=xx-xml.log /command "open nabios_22"
"option echo on" "option batch on" "option confirm off" "option transfer binary"
"cd /home/de_parexel" "put xx.log.last /home/xx.log" "put xx.run /home//sync_xx.run.log"
"option batch continue" "mkdir sync" "option batch on" "option exclude D:\ECGdata\Holter\"
"synchronize remote -mirror -criteria=both ""D:\ECGData"" sync"
"synchronize local -mirror -criteria=both ""D:\ECGData.in"" sync.back"

Hope it helps.

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

Thanks for the logs.

I'm sending you an email with a development version of WinSCP to the address you have used to register on this forum.

great, the dev build you sent me works with the junction.
let me know if you need the logfile.

WinSCP-20160120rjunction-Portable.zip
WinSCP Version 5.8.2 (Dev Build 6145 2016-01-20)


btw. 5.8.2 is much faster !
when nothing is to transfer
5.7.6 need 3 sec for total sync connection (sftp, private key-login)
5.8.2dev only 600 msec

will wait for the 5.8 release.

many thanks

Thanks for your feedback.
