Caching returning wrong directory, can I turn it off?

2014-06-03 19:10

I am using WinSCP scripting to upload files to the same server, but different folders. I use separate scripts for this. I call these at least twice an hour. It looks like the directory caching is failing and it is causing the files to not be uploaded properly. One script I am attempting to change the directory to ...eaimages and it looks like it is changing it to ...mfimages. mfimages is used in the other script and I don't know how/why it is popping up here.

See the log below:

2014-06-03 12:51:30.382 Script: cd /public_ftp/eaimages
2014-06-03 12:51:30.382 Cached directory change via "/public_ftp/eaimages" to "//PWD/public_ftp/mfimages=//PWD/=//PWD"/.
2014-06-03 12:51:30.382 Getting current directory name.
2014-06-03 12:51:30.382 Script: //PWD/public_ftp/mfimages=//PWD/=//PWD
2014-06-03 12:51:30.383 Script: put "C:\....."
2014-06-03 12:51:30.383 Copying 1 files/directories to remote directory "//PWD/public_ftp/mfimages=//PWD/=//PWD"

It then attempts to upload the files to the wrong directory, but from what I can see – the file goes into the void. It never shows up anywhere even though it spends time sending it.

I use the /public_ftp/mfimages in another script so I can see why it is caching. I just think there is a bug and I don't want to mess with it. I just want to turn off caching for now and get this working again.

Well, I found the missing files that it is uploading.

The are being put into this folder:

/PWD/public_ftp/mfimages=/PWD/=/PWD

This is crazy.

I tried turning off directory caching in the graphical interface like the docs say I can do and it had no effect.

The logs still say it is using cache and permanent cache

Please see How do I configure site, transfer and/or any other settings for which there are no script commands?

Though I would appreciate if you help us fixing the bug, as you seem to know what it causing the wrong caching.

Also, it is always better to run the script is isolated environment. Then problems like this won't emerge:

Same problem here with wrong //PWD cached directory

2016-10-27 16:33

I experience the same //PWD issue with WinSCP 5.5.3 (build 4214), here is my log when I try to change the current directory to yann and delete the about.html file in this directory just after the session opening:

> 2016-10-27 17:19:56.923 Script: cd yann
. 2016-10-27 17:19:56.923 Cached directory change via "yann" to "//PWD".
. 2016-10-27 17:19:56.923 Getting current directory name.
< 2016-10-27 17:19:56.923 Script: //PWD
> 2016-10-27 17:19:56.924 Script: rm about.html
. 2016-10-27 17:19:56.924 Listing file "about.html".
. 2016-10-27 17:19:56.924 Retrieving directory listing...

. 2016-10-27 17:19:56.939 Could not retrieve directory listing
. 2016-10-27 17:19:56.939 LIST with -a failed, walling back to pure LIST
. 2016-10-27 17:19:56.939 Retrieving directory listing...
> 2016-10-27 17:19:56.939 CWD /PWD/
< 2016-10-27 17:19:56.950 550 /PWD/: No such file or directory
. 2016-10-27 17:19:56.950 Could not retrieve directory listing
< 2016-10-27 17:19:56.951 Script: Can't get attributes of file 'about.html'.
< 2016-10-27 17:19:56.951 Script: Could not retrieve directory listing

Obviously, the problem is with the cached directory change via yann to //PWD

I can't explain the problem, an I'd like to know if there is an option to disable caching while scripting (I use winscp.com). I see the /rawsetting parameter, but in the winscp.ini file, the CacheDirectories and CacheDirectoryChanges are [Sessions/xxxx] parameters, and not [Configuration/xxx] parameters.

So the caching seems impossible to disable...the best way would be to delete the cache from the hard drive before running my script, but I can't figure out where it is stored ? I'll investigate to find and delete the cache, but in the next release of WinSCP, could you add a script command to clear the cached directories? It could also be a new option parameter (option cachedir on|off) for instance.

Thanks.

[Solved] Same problem here with wrong //PWD cached directory

2016-10-28 10:51

For anyone interested, I find that the cached directories are stored in the [Configuration\CDCache] entry of the winscp.ini file. I now just empty the section before starting my script, and it works. Anyway, if we could disable this with a new option command value like suggested in my previous post, it would be easier to address.

In general, the correct solution is to isolate script from GUI configuration using the /ini=nul command-line switch:
