    <p>I'm working on reading a zip file stored in a Google Cloud Storage bucket from a Google App Engine application, using the Google Cloud Storage Java API. It's work fine for small files, but when I try to read the real file I need (25Mb compressed) I get a ApplicationError: 10 exception. The tests are done the application deployed on GAE.</p> <p>I may have understand that ApplicationError: 10 is thrown when the file is opened for too long (+ than 30s) see : <a href="https://groups.google.com/forum/?fromgroups#!topic/google-appengine-java/5XBVaVDKvvs" rel="nofollow">https://groups.google.com/forum/?fromgroups#!topic/google-appengine-java/5XBVaVDKvvs</a>, but I'm still struggling to get this thing work.</p> <p>Thanks for your help.</p> <p>There is the testing code I used :</p> <pre class="lang-java prettyprint-override"><code>FileService fileService = FileServiceFactory.getFileService(); AppEngineFile readableFile = new AppEngineFile("/gs/xxxx-my-bucket/xxx-bigfile.zip"); FileReadChannel readChannel = fileService.openReadChannel(readableFile, false); ZipInputStream zis = new ZipInputStream(Channels.newInputStream(readChannel)); ZipEntry ze = null; while ((ze = zis.getNextEntry()) != null) { resp.getOutputStream().println("Unzipping " + ze.getName()); for (int c = zis.read(); c != -1; c = zis.read()) { resp.getOutputStream().print((char) c); } zis.closeEntry(); } zis.close(); </code></pre> <p>The stacktrace I get is :</p>

    1. COI don't have any brilliant ideas, but perhaps you can try and just download the file to your local computer without unzipping it. You can then unzip the local copy. Perhaps that will get rid of the timing issue, if that is indeed the problem, or at least help you better identify what the problem actually is.

    3. CO@Howard : Good idea, I'm going to try the read the data unzipped, like a binary stream, we'll see what it does. BTW, the reader is on GAE, so I cannot just download it to my local computer.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
