I have recently added a post to my blog and keep getting the session aborted
Even when I remove this latest post from the post folder I still get this occurring
TIA
I'm sure it's scattered across this site somewhere, but could you add in your versions, relevant specs, etc. (no clue what the answer is, but couldn't hurt to know what's what!)
Before I run blogdown::serve_site()

Not sure what else would help
Figure those might! Just thought I'd get those in here for when the real brains come to the table 
I'd be worried that it will result in "Well if Mara can't fix it, it's insoluble"
Having not used blogdown before, I assumed that one of the previous builds left some dangling temporary file that was causing issues -- I've seen that in RMarkdown before. Not knowing what those temporary files could be, I downloaded blogdown, created a new site, and it promptly blew up R on the Windows 7 computer I have in front of me. Creating additional sites is touch-and-go; some blow up and some work fine.
It looks like a new build of blogdown hit CRAN on the 1st, and the Windows build was updated on the 5th. That seems like a good place to start investigating the problem.
@nick
Good point about blogdown update. I automatically updated a week ago and this is probably first time I have
created a new post and run serve_site since. No relevant issue on github at first glance so I guess i'll revert to earlier version and retry
Hey @pssguy, I'd try a few things. Please run serve_site() after each suggestion. But please rerun any previous suggestions as you go down the list:
public and blogdown foldersthemes or layout folders please back them outblogdown folder, please empty itHope this helps.
@edgararuiz
Thanks for suggestions. Here is an update
Deleted public folder (as I would normally before running hugo_build)
The only blogdown folder I seem to have is the one with the package
Ran serve_site and crashed
I do not run the default theme but have been using icarus for months
Restarted computer (I always restart R anyways) and it worked Ok 1st time
However, when I added back the new post and re-ran serve_site it aborted again
There was a message something like this
stack imbalance in '<' 43 then 54
With the new post, I cannot see any issues from just running all of its chunks
Does it work if you re-serve the same site multiple times without adding back in the new post? I was getting some inconsistency, which didn't seem to follow an obvious pattern in my brief debugging.
@nick
No you are right. I must have just struck 'lucky' first time. So it does not look like an issue with my new post(?)
The site does build. It appears in my RStudio viewer and I can open in browser but the session still crashes
UPDATE
Tried dev version of blogdown 0.2.2 (same result)
reverted to v 0.1 (the CRAN version until a week ago) and repeated serve_site() attempts all work
Creating a new site with blogdown::new_site() and then subsequently serving it with blogdown::serve_site(), I can eventually crash the R session by clicking on links repeatedly. Sometimes it's while loading the initial page, sometimes after I've clicked on a link up to about 10 times. I might get an error in the console, but it's different every time and doesn't always appear. This potentially appears to be a problem with servr, which I know nothing about.
Any ideas as to how we could narrow down the problem more, @edgararuiz?
@nick - It sounds like what you're describing is an issue that should be opened on the blogdown repo, would you mind doing that?
OK so reverting back to 0.1 the serve_site functions performs fine and I can open all my posts locally
However when I attempt to run hugo_build (still on v 0,1 which has worked fine for months) only the front page gets created
UPDATE
reinstalled v 0.2 to see if hugo_build worked on that but no dice
Hopefully @nick writing an issue will work. I ducked out as I knew you would ask for a reproducible example and that is not that easy - especially when no errors are printed
Sure. I'll see if I can make it any more reproducible, but that sounds like a plan.
See footnote 10 in the blogdown book: https://bookdown.org/yihui/blogdown/rstudio-ide.html I'd recommend install.packages('later'). The same issue has been reported recently at https://github.com/rstudio/blogdown/issues/169#issuecomment-341949938
Sure, just when I had narrowed it down to servr::httd and whether daemon was true or false...
I can confirm that installing the later package fixes the problem.
@nick - glad to see your issue resolved
I have run this code
install.packages(c("processx", "later"))
options(blogdown.generator.server = TRUE)
Then restarted computer
blogdown::serve_site() v(0.2) appears to work fine. Looks good in RStudio viewer, opens in browser and i can click links to posts
blogdown::hugo_build() appears to run fine. No errors but a very small index.xml file (39,138 cf 13,612,366 on my remote site)
If I open the public/post/index.html file it works but of course links from it relate to the remote web site
I'm not clear where the post .html files are. Obviously I do not want to deploy and have all my 50+ posts disappear
@pssguy @nick Could you try to run the code below in RStudio and let me know the output?
(blogdown:::Rscript(c("-e", shQuote("httpuv::startDaemonizedServer('127.0.0.1', p <- servr:::random_port(), list(call = function(req) list(status = 200L, body = 'Hello world!', headers = list('Content-Type' = 'text/plain')))); readLines(paste0('http://127.0.0.1:', p), warn = F)"))))
The code is not malicious (trust me ). I just wonder if there is a way to tell if the daemonized server could crash or not on your platform.
