Dave, you'll need something like this:
put the tempname into tFile
put mySoapEnvelope into url("file:" & tFile) -- this is so we don't
pass a load of data on the command line
put "curl -s" into tCurlStr
repeat for each line L in myHttpHeaders -- if you're only setting one
header, you don't need a repeat, of course.
put " -H" && "'" & L & "'" after tCurlStr
end repeat
put " -d" && tFile && tUrl after tCurlStr
put shell(tCurlStr) into tResponse
delete file tFile -- cleanup
If you want to see the whole exchange including headers and
everything, then replace "-s" with "-v" in the third line.
Alternatively, you could try my library (http://futsoft.futilism.com/
revolutionstuff.html),
in which case it would be
put curl.new() into tCurl
curl.setUrl tCurl, tUrl
curl.setHeaders tCurl, myHttpHeaders
curl.setPostData tCurl, mySoapEnvelope
put curl.runTilDone(tCurl) into tResponse

Hi Mark,
I can't figure out the correct format for the "curl" command, or
how to call it from RunRev.
Given that the current post command looks like this:
set the httpHeaders to myHTTPHeader
post mySoapEnvelope to url mySoapURL
put it into myReply
put the result into myResult
How would I do this using curl? The function to send the command is
called from all over the place so I would have to change it in the
low level function, if so then the above is the only data I can get
at and I have to return myReply and myResult in the same format as
the post command would use.
Is this possible using curl?
Thanks a lot
All the Best

Dave, I wonder if it would be worth trying to do the post using
curl (or some other tool) to see if the problem still occurs?
Also, have you looked at what actual bytes the truncated response
ends with ie. is the server sending back something weird?
Best,
Mark

Hi All,
Please see below for the history of this problem. Since then I
have some more information:
I installed WireShark and recreated the problem. When I look at
the captured information, it looks as if the response is being
sent and received by server/client ok. It shows a number of TCP
packets (TCP Segment of a reassembled PDU) and then one block
that shows as HTTP/XML. When I select this block it shows the
packet reassembled as 23782 bytes. However when the error occurs,
the response return by the RunRev post command only shows the
first 2736 bytes, e.g. the rest of the reassembled block is
truncated. I have the dumps as text files but they are too big to
post here.
When I looked up the post command in RunRev it says it is part of
the internet library, however I can't find any source code for
this. Is it available? I'd like to add some trace information so
I can see if this library is being passed the whole block and if
so why is it going wrong on this block.
Is there another way to do this in RunRev? e.g. A alternative to
the "post" command?
Any ideas or suggestions on how to fix or even get a handle of
this problem would be greatly appreciated.
All the Best
Dave
------
I read records from a database, format them, and add them to a
block of data. There is a blocking factor variable, it is set to
200, so I read 200 records from the database, block them into one
big block and send it to the server via a "post" command. The
Server then sends a response which can be variable in length, the
response is in XML format. This process works well 99% of the
time, but sometimes, (and this can be reproduced if the right
data (or the wrong data in this case!) is present in the
database). When this happens the response from the server is
truncated in the middle of an XML node. As far as I can tell the
difference is that by chance, a group of 200 records has caused
the response to be over a certain size.
If I set the BlockingFactor to 50, the problem goes away, but
this causes a major slowdown.
------
It is sending one block at a time, each block contains N records.
There are around 10,500 records in the database.
Each record has an XML node in the reply, depending on the
content of the record sent, it will return different data of
variable size. It appears if the block returned is greater than a
certain size, it is truncated.
Basically the process is:
repeat for all Records in Database
Read Record From Database
Encode as XML
Add to end of SendDataBlock
if the number of records in SendDataBloack > SendBlockingFactor then
post SendDataBlock
get response
process response
put empty into SendDataBlock
end if
end repeat
