[jira] [Updated] (GUACAMOLE-1247) Failure to get SFTP list when
there are many file lists
[ https://issues.apache.org/jira/browse/GUACAMOLE-1247?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
kwangheelee updated GUACAMOLE-1247:
-----------------------------------
Description:
When there are many files in the Linux directory, an error occurs and the connection is disconnected.
Currently, there are more than 40,000 files in a specific directory, and an error occurs when searching the file list through SFTP. I think, this case is not ideal, but some users operate servers that way.
After profiling to find the cause of the problem, it seems that the connection is disconnected because a lot of time is consumed when rendering the DOM after parsing the json by getting the list of SFTP files. (Please refer to the attached photos.)
{code:java}
// guacFileBrowser.js
// guacFileBrowser.js// guacFileBrowser.js// Watch directory contents once file template is available$templateRequest('app/client/templates/file.html').then(function fileTemplateRetrieved(html) {
// Store file template statically fileTemplate = html;
// Update the contents of the file browser whenever the current directory (or its contents) changes $scope.$watch('filesystem.currentDirectory.files', function currentDirectoryChanged(files) {
// Clear current content currentDirectoryContents.html('');
// Display all files within current directory, sorted angular.forEach(sortFiles(files), function displayFile(file) { currentDirectoryContents.append(createFileElement(file)); });
});
}, angular.noop); // end retrieve file template{code}
In my opinion, it takes a lot of time to render the DOM. If you use the lazy loading technique, it seems that you can immediately show the list to the user without disconnecting.
Thanks.
