invalid 'n' argument in upload

[vanatteveldt]

There is an intermittent problem where the server does not return a content-length.

This causes the error reported e.g. at

• https://support.rstudio.com/hc/communities/public/questions/203058566-Publishing-html-file
• https://support.rstudio.com/hc/communities/public/questions/203561536-Is-there-a-page-size-limit-fo-publish-in-Rpubs-

If I call rpubsupload a number of times with the same file and title, it 'sometimes' gives the error, in my session in at least 50% of cases. I've added a message(resp) to line 176, showing the received header.

This call went fine:

$continueUrl
[1] "http://rpubs.com/publish/claim/38176/bbdc1337768f428193ed9c8c6e1384f7"

But the next one resulted in the error:

 Error in readBin(conn, what = "raw", n = contentLength) : 
  invalid 'n' argument 

I have been testing upload code so it is quite possible that there is something weird in my account (vanatteveldt), e.g. a lot of aborted upload attempts where I never visited the 'continue' page.

Note: the .Rprofile workaround suggested in the first link above did not solve the problem for me

I can confirm that the error no longer occurs after installing the patch, thanks a lot!

It works for me.

remove.packages("markdown")
library(devtools)
install_github('rstudio/markdown')

rpubsUpload('test','test.html')

But not with the gui (clicking knit HTML, then 'publish' in the results window... I get the same

I'm not sure which version this PR (rstudio/rstudio#186) eventually went to. Cc @jjallaire

That fix is in RStudio 0.98.1087 so if you update to it then everything
should work fine.
