Hi!

First post! Yay! Smile

I have discovered a behavior that is, in my view, a bit strange. When i try to list a directory using ssh_sftp:list_dir/2 on a directory containing more than 100 files, it returns a list with exactly 100 files. The files seem to be a random selection (maybe sorted on creation date?).


Here is an example, trying to list a directory containing more than 44,000 files:

{ok, Files} = ssh_sftp:list_dir(Server, "/var/ardendo/tmp/soap"), {Files, length(Files)}.
{["ARDOME-SOAP-subtitleapi-getSubtitleList-2008-03-12-14:39:27.xml",
"ARDOME-SOAP-infoapi-getAppConfig-2008-03-12-14:39:27.xml",
"ARDOME-SOAP-usermgrapi-getUserSetting-2008-03-12-14:39:27.xml",
"ARDOME-SOAP-infoapi-getURLs-2008-03-12-14:39:27.xml",
"ARDOME-SOAP-infoapi-getConfVar-2008-03-12-14:39:27.xml",
"ARDOME-SOAP-rundownapi-getRundown-2008-03-12-14:39:27.xml",
"ARDOME-SOAP-publicapi-login-2008-03-12-14:39:26.xml",
[...]|...],
100}

Have anyone encountered this behavior/bug before (or found a working work-around)? Have i perhaps missed some step in the connection procedure? Is it somehow dependent on the implementation/version of ssh on the client machine?

Thanks in advance,
/Christoffer

I found a workaround/fix for this myself -> Upgrade to R12B5, which fixes this bug:

Quote:
OTP-7318 [sftp] - When listing a directory with more than 100 files
only the first 100 where listed. This has now been fixed.


(I need to come out from my programming cocoon more often...)

Thanks for sharing Smile I was looking for a solution for this after I had seen your post but couldn't find any.
