I'm not sure how this would work in your context, but one way to break
up a file into pieces is to use open / read / close like this:
# assumes LC 9.0.2
# tMyFolder = path of folder containing the file to upload
# tMyFileShortFilename = 'short' filename of file to upload - no
path, just the filename
# tMyFilePath = full path of file to upload
filter files(tMyFolder, "detailed") with tMyFileShortFilename & ",*"
into tFileDescription
put item 2 of tFileDescription into tBytesRemaining
put 0 into tBytesProcessed
put 157286400 into tChunkSize -- 150 MB
put tChunkSize into tBytesThisRead
open file tMyFilePath for binary read
repeat until tBytesRemaining = 0
read from file tMyFilePath for tBytesThisRead
subtract length(it) from tBytesRemaining
_processChunk it
put min(tChunkSize, tBytesRemaining) into tBytesThisRead
end repeat
close file tMyFilePath
Your upload would be done in the '_processChunk' handler.

I'm getting a little closer...
1. how do I break fileContents into smaller pieces?
2. how do I properly calculate the pOffset value?
Matthias Rebbe via use-livecode wrote
Hey pink
Yes, you are just going to put 150MB at a time into the pData parameter
and
ship it.
I have not uploaded any binary files, just encoded text files, so you may
have to fiddle with encoding to make sure you don't get into any trouble.
You should be able to open/read the files using
put url "binfile:/"&somefilename into fileContents

the phxDropbox library is for v1 of the Dropbox API, which has been

what I need is to get a handle of the upload session commands, how do I

under the documentation for dropboxUpload, it states it shouldn't be
used
for files larger than 150MB, the video files will all be around 800MB
I've been looking through the stack, but cannot find the answers I am
looking for. SO I am still not clear how I should get my file into
pData
and pData is just a chunk of the data? How do I make that chunk out of
the
whole and where do I get pOffset from?
Matthias Rebbe via use-livecode wrote
Hey, pink, thanks for the clarification.
First of all, is there a reason why you are doing it this way instead
of
using dropboxUpload? If you use dropboxUpload you can do it all in
one
shot.
Gerard's stack explains the process and how to use the various
commands
Doing it the way you are doing it, you would start with sessionStart
and
then you would repeatedly call sessionAppend
pOffset is the length of what you have already sent because there are
no
guarantees that dropbox will get your file stream in order, so if it
gets
them out of order and pData isn't the same length for each call to
append,
the only way dropbox knows where to put the data it just received is
if
you
tell it where to put it.
pData should be at most 150mb per call.

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
and did a little diving.
And God said, "This is good."
