** Description changed: - whoopsie's server_response code is using "g_string_append" instead of - "g_string_append_len" which has the knock on effect of sending too much - data to its "handle_response". This ends up being a problem if the daisy - servers are running on Ubuntu 18.04 instead of Ubuntu 16.04. + [Impact] + whoopsie's server_response code is using "g_string_append" instead of "g_string_append_len" which has the knock on effect of sending too much data to its "handle_response". This ends up being a problem if the daisy servers are running on Ubuntu 18.04 instead of Ubuntu 16.04. Here's an example when using whoopsie on groovy to send a crash to a bionic daisy server: [15:35:30] Sent; server replied with: No error [15:35:30] Response code: 200 [15:35:30] Initial response data is: 2bbb776e-64e6-11eb-a8d6-00163eddedf4 OOPSID 0 [15:35:30] Got command: OOPSID We can see a fair number of extra characters (\n0\n\n) after the OOSID command. This becomes more problematic when daisy requests a core dump from the client as the CORE command won't match and the client will never send the core dump. + + [Test Case] + Setup a Bionic version of the Error Tracker: + 0) modify /etc/hosts so daisy.staging.ubuntu.com points to the IP of the apache server for daisy + 1) sudo service stop whoopsie + 2) sudo CRASH_DB_URL=https://daisy.staging.ubuntu.com whoopsie -f + 3) Run test/submit-crash test-crashes/hirsute/amd64/_bin_cat.2001.crash + 4) check the whoopsie log file for "Got command: OOPSID" and extra data. + + With the version of whoopsie from -proposed this will not happen. + Additionally, a regression test should be run against the staging + version of the error tracker by removing the entry from /etc/hosts for + the daisy.staging server. After confirming that one test crash works one + should also send a python crash, and an end of life release crash as + those all generate different response codes from the server. + + [Regression Potential] + The code being changed is clearly wrong and doesn't confirm to the curl API https://curl.se/libcurl/c/CURLOPT_WRITEFUNCTION.html. Additionallly, this is similar to the code before r707 of daisy which introduced this change so there is little chance of regression. That being said we are running a regression test to ensure whoopsie works with servers running Ubuntu 16.04.
