API response contains "* Connection #0 bamboo.<companyname>.com left intact."

james_mckean April 14, 2022

I am testing some Bamboo APIs with the goal of writing a report requested by management. I am using cURL until I figure out what works and then will probably move to Ansible.

In all responses I get a string "* Connection #0 bamboo.<companyname>.com left intact." Usually, this is the last line before the json formatted payload and causes no problems.  But if the response is long, the string may get inserted into the middle of the json payload resulting in broken json.

Here is an example snippet (I added the bold)

. . . "plan":{"shortName":"Mod of HelloWorld","shortKey":"MH","type":"chain","enabled":true,"link":{"href":"<companyname>com/rest/api/latest/plan/TABVTJP* Connection #0 to host<companyname>.com left intact

-MH","rel":"self"},"key":"TABXXJP-YY","name":"Test availability of BITBUCKET_BRANCH variable to java program - Mod of HelloWorld","planKey":{"key":"TABXXJP-YY"}}, . . .

Does anyone have any suggestions?

Hello @james_mckean


Adding a header "Connection: close" to your cURL command line should solve the problem:

  • curl -v -H "Connection: close"<companyname>.com


From this page:

Why is the connection left intact:

The connection is left intact, because the server allowed it to stay open and CURL no need to close it after you receive the response for the request sent. That’s why the requests return ‘Connection: keep-alive‘ headers when you expect ‘Connection:close

If you wanted to close the connection, then you could send CURL request with ‘Connection: close‘ as shown below and you could see ‘* Closing connection 0‘ in the response.

Hmm. Not exactly. Now it drops the "closing connection " notification into the json response, again breaking the json.

Hello @james_mckean

That message comes from the SSL library that cURL is linked to (usually OpenSSL/LibreSSL) and will show up when using curl with a "-v" flag. Those messages are sent to the standard error output and can be discarded by your script.

Try running it without the "-v" flag.

That did it.  Thanks!
