From The Course page when I click download all submission zip file is downloaded. But I am not able to extract zip file as it gives following error.
Archive: CS_632-2013-2-Project_final_submission-27762.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of CS_632-2013-2-Project_final_submission-27762.zip or
CS_632-2013-2-Project_final_submission-27762.zip.zip, and cannot find CS_632-2013-2-Project_final_submission-27762.zip.ZIP, period.
This error is coming for all course submission downloads.
I'm guessing you are right clicking the link and saving? This won't work, you need to actually click the link which will then automatically download the correct file.

Search for ZIP Extractor and install it. Now, you can select any archived file in Google Drive for extraction. Select the file and right-click to Open with the ZIP Extractor for ZIP files stored in Drive
I am trying to upload an ipa file (written in Swift) to our MDM console (AirWatch). The console is .Net, and when I try to upload I get a message saying the path contains illegal characters. The path does not, and I can upload other ipa files to MDM, so I'm left with something wrong with the ipa itself. The MDM software reads the IPA when it's uploading it to determine version and other information. Anyone got any ideas?
-MJC
I've found that one of the folders embedded in the .ipa file has the 'cross' character (hex=10, ascii=16, DLE) in the 'LaunchScreen.storyboardc' folder.
This can be seen by opening the .ipa file using 7zip in Windows.
When we remove this folder using 7zip, Airwatch accepts the ipa file.
I downloaded todo.txt-touch-ios-master zip file from github.But when i open this applicaiton in xcode 4.4.DropboxApiKey.h file is not found.I got the erors like \
'<'command line'>':1:10: fatal error: 'DropboxApiKey.h' file not found
In file included from '<'built-in'>'
project folder path'<'command line'>':1: 'DropboxApiKey.h' file not found in project folder path /'<'command line'>'
How can i get that file.I added manually That file.But it's not working.Again same errors came.
I found a project on GitHub called todo.txt-touch-ios, so I assume that's what you're looking at. If so, I see a file there called sample-DropboxApiKey.h. My guess would be that you should copy or rename that file to DropboxApiKey.h and plug in your own app key and secret.
You can obtain your own app key and secret by creating an app at the Dropbox app console: https://www.dropbox.com/developers/apps. Create a "core API" app, as it appears that's what this code uses. I can't quickly tell from reading the code whether the app needs to have "app folder" or "full Dropbox" permission, so you might try one and then the other.
See also https://github.com/ginatrapani/todo.txt-touch-ios/issues/163, which seems to confirm my guess.
I have a file upload page that takes a file and parses it.
Order of Events
user uploads file
uploaded file gets copied
copied file gets it's encoding checked, with CPDetector
determined encoding from the copied file is used to parse the original uploaded file
FileNotFoundException on Solaris Test Server during BufferedReader creation.
copied file is deleted
uploaded file is parsed/verified
parsed data is saved to a database
uploaded file is deleted (I can't remember if I'm doing this or Tomcat is.)
The Whole process works on my Windows 7 workstation. As noted above it does not work on my Solaris Test Server. Something(I Suspect Tomcat) is deleting the uploaded file before I can finish parsing it.
I've watched the directory during the process and an uploaded file does indeed get created, but it lasts less than a second before being deleted. Also It's supposed to go into /opt/tomcat/ but seems be getting created in the /var/opt/csw/tomcat6/temp/ directory instead.
Thanks for any help
I realize it's probably bad form to answer my own question like this but I wanted to leave this here in-case it helps someone else.
The Problem turned out to be How I was accessing the files.
I had hard-coded file paths, for windows, and Database loaded ones for the test server.
I switched those to using System.getProperty("catalina.home")+"/temp/" + filename
I'm also copying the temp file a second time so I end up with:
Order of Events (changes are in bold)
user uploads file
uploaded file gets copied
copied file gets it's encoding checked, with CPDetector
uploaded file gets copied again to ensure a copy survives to be parsed
determined encoding from the copied file is used to parse the original uploaded file
copy used for encoding detection is deleted
copy for parse is parsed/verified
parsed data is saved to a database
parsed file is deleted.
uploaded file is deleted (I'm not sure if I'm doing this or Tomcat is.)
I am using CGI.pm version 3.10 for file upload using Perl. I have a Perl script which uploads the file and one of my application keeps track of different revisions of the uploaded document with check-in check-out facility.
Re-creational steps:
I have done a checkout(download a file) using my application (which is web based uses apache).
Logout from current user session.
Login again with same credentials and then check-in (upload) a new file.
Output:
Upload successful
Perl upload script shows the correct uploaded data
New revision of the file created
Output is correct and expected except the one case which is the issue
Issue:
The content of the newly uploaded file are same as the content of the last uploaded revision in DB.
I am using a temp folder for copying the new content and if I print the new content in upload script then it comes correct. I have no limit on CGI upload size. It seems somewhere in CGI environment it fails might be the version i am using. I am not using taint mode.
Can anybody helps me to understand what might be the possible reason?
Sounds like you're getting the old file name stuck in the file upload field. Not sure if that can happen for filefield but this is a feature for other field types.
Try adding the -nosticky pragma, eg, use CGI qw(-nosticky :all);. Another pragma to try is -private_tempfiles, which should prevent the user from "eavesdropping" even on their own uploads.
Of course, it could be that you need to localize (my) some variable or add -force to the filefield.
I found the issue. The reason was destination path of the copied file was not correct, this was because my application one of event maps the path of copied file to different directory and this path is storing in user session. This happens only when I run the event just before staring upload script. This was the reason that it was hard to catch. As upload script is designed to pick the new copied file from same path so it always end up uploading the same file in DB with another revision. The new copied file lying in new path.
Solved by mapping correct path before upload.
Thanks
