I open file by SimGrid framework:
msg_file_t file = MSG_file_open("/scratch/bin/tesh", NULL);
XBT_INFO("file size is %zd", MSG_file_get_size(file));
It's OK:
[carl:host:(1) 0.000000] [remote_io/INFO] file size is 356434
Then I want to set some data to this file. Firstly, I create typedef structure:
typedef struct {
char* number_used;
}data, *dataPtr;
Then I set data with MSG_file_set_data to this file:
dataPtr data_1 = xbt_new(data, 1);
data_1->number_used = xbt_strdup("1");
MSG_file_set_data(file, data);
But after closing file I can't get the value of data_1->number_used:
file = MSG_file_open("/scratch/bin/tesh", NULL);
dataPtr data_2 = MSG_file_get_data(file);
XBT_INFO("number used %s", data_2->number_used);
It gives segmentation fault and value of data_2 is null. What did I do wrong?
A msg_file_t object only exists between the MSG_file_open and MSG_file_close calls. Calling again MSG_file_open on the same file name creates a new msg_file_t object (a new descriptor). Then user data attached to a msg_file_t are not persistent across multiple open/close on a file name.

I am developing an app that uploads PDF files to a specific Google Drive folder. The file name includes the current date. The following code is for my DriveServiceHelper.class that is used to create a folder in Google Drive and then upload the PDF files into that folder using its folderID:
public class DriveServiceHelper {
Calendar c = Calendar.getInstance();
Date d = c.getTime();
SimpleDateFormat df = new SimpleDateFormat("dd-MM-yyyy");
String currentDate = df.format(d);
String ps_FolderKey;
private final Executor mExecutor = Executors.newSingleThreadExecutor();
private Drive mDriveService;
public DriveServiceHelper(Drive mDriveService) {
this.mDriveService = mDriveService;
}
public Task<String> createFolder() {
return Tasks.call(mExecutor, () -> {
File folderMetadata = new File();
folderMetadata.setName("Covid Assessment Sheets");
folderMetadata.setMimeType("application/vnd.google-apps.folder");
File myFolder = null;
try {
myFolder = mDriveService.files().create(folderMetadata)
.setFields("id")
.execute();
System.out.println("Folder ID: " + myFolder.getId());
} catch (Exception e) {
e.printStackTrace();
}
if (myFolder == null) {
throw new IOException("Null result when requesting file creation");
}
ps_FolderKey = myFolder.getId();
return ps_FolderKey;
});
}
public Task<String> createFilePDF(String filePath, String folderId) {
return Tasks.call(mExecutor, () -> {
File fileMetaData = new File();
fileMetaData.setName("Covid Assessment # " + currentDate);
fileMetaData.setParents(Collections.singletonList(folderId));
java.io.File file = new java.io.File(filePath);
FileContent mediaContent = new FileContent("application/pdf", file);
File myFile = null;
try {
myFile = mDriveService.files().create(fileMetaData, mediaContent).execute();
} catch (Exception e) {
e.printStackTrace();
}
if (myFile == null) {
throw new IOException("Null result when requesting file creation");
}
return myFile.getId();
});
}
}
When uploading the same PDF to a Google Drive folder, I want to overwrite files with the same name, but instead duplicate files are created in the folder as the fileID assigned is different even if file name is the same.
Please help me understand how I should go about this, to automatically overwrite/replace files that already exist with the same name (each file is differentiated by date), and a new PDF file is created if the PDF file does not exist in the folder.
I understand that I might be using the deprecated Drive API, but I was unable to find other solutions online to help me implement what I need. I also came across solutions that include queries to search for existing Google Drive files, but I am not sure I understand how to use it to make it work for me.
Thank you
Google Drive supports multiple files with the same name
Thus, by creating a file with an already existing name, you will not automatically overwrite the old file.
Instead you should do the following:
Use the method Files:list with the query name = 'Covid Assessment Sheets' to find the already existing file(s) with the same name
If desired, you can narrow down the results by also specifying the mimeType and the parent folder (parents)
Retrieve the id of the list result(s)
Use the method Files:delete to delete the existing file
Proceed to create a new file as you are already doing
In Java this would look as following:
FileList result = DriveService.files().list()
.setQ("name = 'Covid Assessment Sheets'");
.setFields("files(id)")
.execute();
List<File> files = result.getFiles();
for (File file : files) {
DriveService.files().delete(file.getId()).execute();
}
An alternative approach would be to update the contents of the already existing file instead of creating a new one.
There is a strange behavior when I try create an image from view in Revit via API. For some reason the target file sometimes is "png", sometimes "jpg" (for different View3D). As a workaround I check file existence and replace the extension, but I think it's not a good solution. The idea was taken from
https://thebuildingcoder.typepad.com/blog/2013/08/setting-a-default-3d-view-orientation.html
public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
UIDocument uidoc = commandData.Application.ActiveUIDocument;
Document doc = uidoc.Document;
var tempFileName = Path.ChangeExtension(Path.GetRandomFileName(), "png");
string tempImageFile;
try
{
tempImageFile = Path.Combine(Path.GetTempPath(), tempFileName);
}
catch (IOException)
{
return Result.Failed;
}
var opt = new ImageExportOptions
{
ZoomType = ZoomFitType.Zoom,
FilePath = tempImageFile,
FitDirection = FitDirectionType.Horizontal,
HLRandWFViewsFileType = ImageFileType.PNG,
ImageResolution = ImageResolution.DPI_300,
};
doc.ExportImage(opt);
Debug.WriteLine(File.Exists(tempImageFile) ? "File exists." : "File does not exist.");
return Result.Succeeded;
}
}
Steps to reproduce:
Create external command (implement IExternalCommand interface)
Use provided above implementation of Execute method
Open Revit 2020 sample model (rac_basic_sample_project.rvt)
Select 3D Views->Selection Perspective (or Kitchen)
Execute external command
Check the result of doc.ExportImage(opt) command
AR: Result file has "jpg" extension instead of "png"
ER: File should be "png".
PS. If you select 3D Views->{3D} file has extension "png"
Look at screens
How can I generate several text files at the same time locally?
I am using the method:
throw new PXRedirectToFileException (file, true);
![enter image description here][1]
However, this method only generates 1 text file. I need more than 1 text file to be generated at a time.
List<object> data1099Misc = new List<object> { };
ARInvoice ari = Base.Document.Current;
foreach (xvrFSCab diot in PXSelect<xvrFSCab,
Where<xvrFSCab.invoiceNbr,
In<Required<xvrFSCab.invoiceNbr>>>>.Select(Base, ari.InvoiceNbr))
{
data1099Misc.Add(CreatePayerARecord(diot));
}
FixedLengthFile flatFile = new FixedLengthFile();
flatFile.WriteToFile(data1099Misc, sw);
sw.Flush();
sw.FlushAsync();
int cont = 0;
while ( cont<3)
{
cont = cont + 1;
string path = "DIOTJOSE" + ".txt";
PX.SM.FileInfo file = new PX.SM.FileInfo(path, null, stream.ToArray());
throw new PXRedirectToFileException(file, true);
}
Acumatica had the same issue when they had to open multiple reports at one click (with RedirectException).
For this reason Acumatica supports multiple RequiredException only for Reports.
They have a method called "CombineReport" that works with multiple PXReportRequiredException (PXReportsRedirectList)
Sad part is that they did not make something for other RequiredException or RedirectException
I tried to make my own "Combine" method but I was not able to create it just because the RedirectHelper.TryRedirect method use hardcoded types of the RedirectException inside body instead to use an generic or base object :(
I need to update a table that is shared. The info for this table is first collected into an Excel table files and then uploaded to google drive every day. I found some code that converts the .xls files to a google spreadsheet file, I need to copy the data from this converted file and update the shared one each day. My problem now is that the file I will use for updating the shared spreadsheet will be different eachday, so how can I have the script to get the new file ID eachday. I need these updates to be done automatically each day.
This is the code I have found so far but can't seem to get it to work. First part converts the .xls file to google spreadsheet file that part works but i cant seem to get the function for updating the shared table to work, i cant get the ID of the created file. Would also be nice if a function an be added to the code to to delete the files after they have been converted and the shared table has been updated with them.
function importXLS(){
var files = DriveApp.searchFiles('title contains ".xls"');
var destinationFolderId = "ID of folder with .xls file that is being converted each day";
var existingFileNames = getFilesInFolder(destinationFolderId);
while(files.hasNext()){
var xFile = files.next();
var name = xFile.getName();
try {
if (existingFileNames[name] && (name.indexOf('.xls')>-1)) {
var ID = xFile.getId();
var xBlob = xFile.getBlob();
var newFile = { title : name,
key : ID,
'parents':[{"id": destinationFolderId}]
}
file = Drive.Files.insert(newFile, xBlob, {
convert: true
});
}
} catch (error) {
console.error("Error with file " + name + ": " + error);
}
}
}
/**
* Get an object of all file names in the specified folder.
* #param {string} folderId
* #returns {Object} files - {filename: true}
*/
function getFilesInFolder(folderId) {
var folder = DriveApp.getFolderById(folderId);
var filesIterator = folder.getFiles();
var files = {};
while (filesIterator.hasNext()) {
var file = filesIterator.next();
files[file.getName()] = true;
}
return files;
}
function CopyContent() {
var ID = importXLS(ID);
var source = SpreadsheetApp.openById(importXLS(ID));//the source needs to be the new file i get eachday
var sheet = source.getSheets()[0];
var destination = SpreadsheetApp.openById("ID of shared table here");
sheet.copyTo(destination);
}
Use Paste Special > Paste values only
The copypastetype to use is PASTE_VALUES
Example from https://developers.google.com/apps-script/reference/spreadsheet/range#copytodestination-copypastetype-transposed
// The code below copies only the values of the first 5 columns over to the 6th column.
var sheet = SpreadsheetApp.getActiveSheet();
sheet.getRange("A:E").copyTo(sheet.getRange("F1"), spreadsheetApp.CopyPasteType.PASTE_VALUES);
I have a JAR file with following structure:
com
-- pack1
-- A.class
-- pack2
-- AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.class
When I try to read, extract or rename pack2/AA...AA.class (which has a 262 byte long filename) both Linux and Windows say filename is too long. Renaming inside the JAR file doesn't also work.
Any ideas how to solve this issue and make the long class file readable?
This pages lists the usual limits of file systems: http://en.wikipedia.org/wiki/Comparison_of_file_systems
As you can see in the "Limits" section, almost no file system allows more than 255 characters.
Your only chance is to write a program that extracts the files and shortens file names which are too long. Java at least should be able to open the archive (try jar -tvf to list the content; if that works, truncating should work as well).
java.util.jar can handle it:
try {
JarFile jarFile = new JarFile("/path/to/target.jar");
Enumeration<JarEntry> jarEntries = jarFile.entries();
int i = 0;
while (jarEntries.hasMoreElements()) {
JarEntry jarEntry = jarEntries.nextElement();
System.out.println("processing entry: " + jarEntry.getName());
InputStream jarFileInputStream = jarFile.getInputStream(jarEntry);
OutputStream jarOutputStream = new FileOutputStream(new File("/tmp/test/test" + (i++) + ".class")); // give temporary name to class
while (jarFileInputStream.available() > 0) {
jarOutputStream.write(jarFileInputStream.read());
}
jarOutputStream.close();
jarFileInputStream.close();
}
} catch (IOException ex) {
Logger.getLogger(JARExtractor.class.getName()).log(Level.SEVERE, null, ex);
}
The output willbe test<n>.class for each class.
