This reverts commit 560c7b874a.
The ot.uuid variable should have the 'sess' scope because it is created
when an OpenTracing filter is attached to a stream. After that, the
stream processing is started and on that occasion the contexts for the
variables that have the range 'txn' and 'req' are initialized. This
means that we cannot use variables with the specified scopes before that
point.
This patch must be backported in 2.5.
When calling the 'basename' command, the argument ${0} is enclosed in
quotation marks. This is necessary if the path of the executable script
(contained in that argument) has "non-standard" elements, such as space
and the like.
Also, in the script 'test-speed.sh' the function sh_exit() has been added
for easier printing of messages at the end of execution.
This patch must be backported as far as 2.4.
At the suggestion of Willy Tarreau, the scope of the 'ot.uuid' variable was
changed from 'sess' to 'txn', so it is now limited to the transaction only.
This one is the last optional module to build with haproxy, so let's move
it to addons/. It was renamed to "ot" as it was the only one whose USE_*
option did not match the directory name, now this is consistent.
Few changes were required, only the Makefile, and doc were adjusted, as
the directory was already self-contained and relocatable.
