+
+Prior versions required editing the tests/xxxx and changing a debug flag.
+However, that has been replaced by two environment variables:
+
+ REGRESS_DEBUG
+ REGRESS_WAIT
+
+If you define REGRESS_DEBUG, e.g.
+
+ REGRESS_DEBUG=1
+ export REGRESS_DEBUG
+
+then run a test, it will display the job and debug output.
+
+If you define REGRESS_WAIT, the script will stop and request:
+
+Start Bacula under debugger and enter anything when ready ...
+
+At this point, you can start any of the daemons under the debugger,
+then answer the message by entering any character. The script will
+then continue. For any daemon or daemons that you have manually started,
+you will see an error message when the script attempts to run a second
+copy, but those messages can be ignored. This makes it reasonably easy
+to run any component or components under the debugger if necessary.
+
+Explicit example:
+
+In shell window 1.
+
+cd regress
+export REGRESS_DEBUG=1
+export REGRESS_WAIT=1
+tests/name-of-script-test
+(wait until it tells you to start the debugger)
+
+In shell window 2
+
+cd regress/bin
+gdb bacula-xx (where xx is the component you want to debug).
+(possibly set a break point -- normally not)
+run -s -f
+(wait for the output to stop)
+
+In shell window 1
+(enter any character or simply a return)
+(ignore the error message it prints complaining that the daemon
+you are debugging is already running, which is in fact the case).
+
+
+That is all there is to it. The debugger window will get some
+output and will stop waiting for input if anything goes wrong
+like a seg fault. At that point, you can enter commands.
+
+The procedure avoids modifying the test scripts and trying to
+find pids and the such. If you want less debug output when
+debugging, don't set REGRESS_DEBUG=1.
+
+===
+
+Also, if you run from time to time on a computer that is not connected
+to the network, please be sure that "hostname" is set to "localhost",
+otherwise, your tests may fail because the hostname used by Bacula's
+./configure cannot be properly resolved.
+
+Anyway, you can debug where it is happening in the source code using the
+following example. For example, here I get the following backtrace:
+
+======= Backtrace: =========
+/lib/libc.so.6[0xb7b9d6e1]
+/lib/libc.so.6(cfree+0x89)[0xb7b9ed79]
+/home/kern/bacula/regress/bin/bacula-fd[0x8082ae5]
+/home/kern/bacula/regress/bin/bacula-fd[0x8082d58]
+/home/kern/bacula/regress/bin/bacula-fd[0x80838ac]
+/home/kern/bacula/regress/bin/bacula-fd[0x807aa3f]
+/home/kern/bacula/regress/bin/bacula-fd[0x807ac29]
+/home/kern/bacula/regress/bin/bacula-fd[0x804d188]
+/lib/libc.so.6(__libc_start_main+0xdc)[0xb7b4ef9c]
+/home/kern/bacula/regress/bin/bacula-fd[0x804cd21]
+
+Now to convert this into something more meaningful, kill off any hung Bacula
+processes. Note the one that was running -- above you see that it was
+bacula-fd, then bring the same binary up in the debugger. Then start at the
+first bacula-fd line, and feed the hex number to gdb as follows:
+
+info symbol 0x8082ae5
+free_addresses(dlist*) + 53 in section .text
+
+info symbol 0x8082d58
+add_address(dlist**, IPADDR::i_type, unsigned short, int, char const*, char
+const*, char**) + 568 in section .text
+
+Testing a Binary Installation:
+
+If you have installed your Bacula from a binary release such as (rpms or
+debs), you can still run regression tests on it. First, make sure that your
+regression config file uses the same catalog backend as your installed
+binaries. Then define the variables bin and scripts variables in your config
+file.
+
+Example:
+bin=/opt/bacula/bin
+scripts=/opt/bacula/scripts
+conf=/opt/bacula/etc
+
+The ./scripts/prepare-other-loc will tweak the regress scripts to use
+your binary location. You will need to run it manually once before you run any
+regression tests.
+
+$ scripts/prepare-other-loc
+$ tests/backup-bacula-test
+...
+
+All regression scripts must be run by hand or by calling the test scripts.
+These are principally scripts that begin with all_... such as all_disk_tests},
+./all_tests
+
+None of the
+./do_disk, ./do_all, ./nightly... scripts will work.
+
+If you want to switch back to running the regression scripts from source, first
+remove the bin, scripts, and conf variables from your config file and
+rerun the make setup step.
