Subject [Bug 60327] New: what does %7F mean in ErrorLogFormat
Date Tue, 01 Nov 2016 13:39:42 GMT

            Bug ID: 60327
           Summary: what does %7F mean in ErrorLogFormat
           Product: Apache httpd-2
           Version: 2.4.23
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
          Assignee: bugs@httpd.apache.org
          Reporter: verne@wvnet.edu
  Target Milestone: ---

as you may recall, ErrorLogFormat is new for 2.4 ... 

three examples at
https://httpd.apache.org/docs/2.4/mod/core.html#errorlogformat have the literal
%7F in them, but no description at all ...



#Example (default format for threaded MPMs)
ErrorLogFormat "[%{u}t] [%-m:%l] [pid %P:tid %T] %7F: %E: [client\ %a] %M% ,\
referer\ %{Referer}i"

#Example (similar to the 2.2.x format)
ErrorLogFormat "[%t] [%l] %7F: %E: [client\ %a] %M% ,\ referer\ %{Referer}i"

#Advanced example with request/connection log IDs
ErrorLogFormat "[%{uc}t] [%-m:%-l] [R:%L] [C:%{C}L] %7F: %E: %M"
[...]



am I missing something ... what does the string/token/item %7F actually do
(ASCII %7F I think is the delete key/character) ?

... when I use ErrorLogFormat on a test server and examine the logs with and
without %7F, I see no difference ... perhaps my simple test does not trigger it
...

or ... is it a documentation typo (three times though??) and has no meaning or
function in ErrorLogFormat and simply needs to be edited out ...
