getSymbols.yahoo() always throws "Error in new.session()"

[abernal30]

Description

When applying the function getSymbols(), it errors and does not return a result.

Minimal, reproducible example

getSymbols("AAPL")
## Error in new.session() : Could not establish session after 5 attempts.

@joshuaulrich,

The issue is located in the function .getHandle and specifically in the local function new.session. All the 5 calls to the yahoo website return with no cookies, hence the function fails.

Looking over the code. I don't see much point in the .gethandle function as the yahoo query is also being built in the .yahooURL function. The only thing that .gethandle gives to .yahooURL is the crumb request to the query.srv. and cb has the value: "" for either query1 or query2. So this part is not needed to get the data.

Removing the .gethandle and removing the crumb part from building the yahoo url in .yahooURL returns the data without any issues.

seeing same issue here

one also needs to get rid of the if statement inside the .getHandle function which stops the process if the number of cookies is zero

if (NROW(curl::handle_cookies(h)) ==0
stop(„Could not establish session after 5 attempts.“)

p.s. thank you for the quick fix! Really appreciate it

@pverspeelt and @alihru thanks for taking a look! I have a patch and am running CRAN and reverse-dependency checks now.

Thanks for helping out @joshuaulrich . Im the author of BatchGetSymbols, which uses quantmod::getSymbols(), and got lots of emails this morning about the issue!

@asaeb1480 please try installing from the 358-getsymbols-new.session branch. It's working for me again.
