The new V1.0.2 has new capabilities to upload attachments to a domino document. My upload code is successful as long a I use files <= 48KB. As soon as I try to upload a larger file, the upload takes place, in the domino document I find an attachment with the right size - but the file is corrupt!
Here's my code (corresponds to example code from appdev pack documentation for larger files):
for (var x = 0; x < files["tskFile"].length; x++) {
let sFilename = files["tskFile"][x].originalname;
let sPath = files["tskFile"][x].path;
let buffer = fs.readFileSync(sPath);
const writable = await db.bulkCreateAttachmentStream({});
writable.on('error', e => {
// An error occurred and the stream is closed
console.error("Error on write ", e)
});
writable.on('response', response => {
// The attachment content was written to the document and a
// response has arrived from the server
console.log(">> File " + sFilename + " saved to doc ")
});
let error;
// Write the image in n chunks
let offset = 0;
const writeRemaining = () => {
if (error) {
return;
}
let draining = true;
while (offset < buffer.length && draining) {
const remainingBytes = buffer.length - offset;
let chunkSize = 16 * 1024;
if (remainingBytes < chunkSize) {
chunkSize = remainingBytes;
}
const chunk = new Uint8Array(
buffer.slice(offset, offset + chunkSize),
);
draining = writable.write(chunk);
offset += chunkSize;
}
if (offset < buffer.length) {
// Buffer is not draining. Write some more once it drains.
writable.once('drain', writeRemaining);
} else {
writable.end();
}
};
writable.file({
unid: unid,
fileName: sFilename,
});
writeRemaining();
} // end forall attachments
Here are my notes.ini variables for my server:
PROTON_MAX_WRITE_ATTACHMENT_MB=30,
PROTON_MAX_ATTACHMENT_CHUNK_KB=50,
PROTON_MIN_ATTACHMENT_CHUNK_KB=8
My error or bug in AppDevPack? Did anyone try this new feature?
