An ssl_bump splicing decision would then trigger + the useless "send the error to the client now" processing logic instead + of going down the "to serve an error, bump the client first" path. + + Furthermore, the ssl_bump evaluation result itself could be surprising + to the admin because ssl_bump (and most other) rules are not meant to be + evaluated for a transaction in an error state. This complicated triage. + + Also polished an important comment to clarify that we want to bump on + error if (and only if) the SslBump feature is applicable to the failed + transaction (i.e., if the ssl_bump rules would have been evaluated if + there were no prior errors). The old comment could have been + misinterpreted that ssl_bump rules must be evaluated to allow an + "ssl_bump splice" match to hide the error. + + This is a Measurement Factory project. +------------------------------------------------------------ +# Bazaar merge directive format 2 (Bazaar 0.90) +# revision_id: squid3@treenet.co.nz-20170208054033-pxqn8rs4yu713ijq +# target_branch: http://bzr.squid-cache.org/bzr/squid3/3.5 +# testament_sha1: 8c3f2a03f86aa1b1484195a63742bc4002ba2359 +# timestamp: 2017-02-08 05:51:15 +0000 +# source_branch: http://bzr.squid-cache.org/bzr/squid3/3.5 +# base_revision_id: squid3@treenet.co.nz-20170128035415-\ +# bpwt79jsobv1rqx3 +# +# Begin patch +=== modified file 'src/client_side_request.cc' +--- src/client_side_request.cc 2017-01-23 02:05:46 +0000 ++++ src/client_side_request.cc 2017-02-08 05:40:33 +0000 +@@ -1442,6 +1442,13 @@ + return false; + } + ++ if (error) { ++ debugs(85, 5, "SslBump applies.
