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
// 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.
