+ | HAProxy regression testing with vtest |
+ +---------------------------------------+
+
+
+The information found in this file are a short starting guide to help you to
+write VTC (Varnish Test Case) scripts (or VTC files) for haproxy regression testing.
+Such VTC files are currently used to test Varnish cache application developed by
+Poul-Henning Kamp. A very big thanks you to him for having helped you to add
+our haproxy C modules to vtest tool. Note that vtest was formally developed for
+varnish cache reg testing and was named varnishtest. vtest is an haproxy specific
+version of varnishtest program which reuses the non varnish cache specific code.
+
+A lot of general information about how to write VTC files may be found in 'man/vtc.7'
+manual of varnish cache sources directory or directly on the web here:
+
+ https://varnish-cache.org/docs/trunk/reference/vtc.html
+
+It is *highly* recommended to read this manual before asking to haproxy ML. This
+documentation only deals with the vtest support for haproxy.
+
+
+vtest installation
+------------------------
+
+To use vtest you will have to download and compile the recent vtest
+sources found at https://github.com/vtest/VTest.
+
+To compile vtest:
+
+ $ cd VTest
+ $ make vtest
+
+Note that varnishtest may be also compiled but not without the varnish cache
+sources already compiled:
+
+ $ VARNISH_SRC=<...> make varnishtest
+
+After having compiled these sources, the vtest executable location is at the
+root of the vtest sources directory.
+
+
+vtest execution
+---------------------
+
+vtest is able to search for the haproxy executable file it is supposed to
+launch thanks to the PATH environment variable. To force the executable to be used by
+vtest, the HAPROXY_PROGRAM environment variable for vtest may be
+typically set as follows:
+
+ $ HAPROXY_PROGRAM=~/srcs/haproxy/haproxy vtest ...
+
+vtest program comes with interesting options. The most interesting are:
+
+ -t Timeout in seconds to abort the test if some launched program
+ -v By default, vtest does not dump the outputs of process it launched
+ when the test passes. With this option the outputs are dumped even
+ when the test passes.
+ -L to always keep the temporary VTC directories.
+ -l to keep the temporary VTC directories only when the test fails.
+
+About haproxy, when launched by vtest, -d option is enabled by default.
+
+
+How to write VTC files
+----------------------
+
+A VTC file must start with a "varnishtest" or "vtest" command line followed by a
+descriptive line enclosed by double quotes. This is not specific to the VTC files
+for haproxy.
+
+The VTC files for haproxy must also contain a "feature ignore_unknown_macro" line
+if any macro is used for haproxy in this file. This is due to the fact that
+vtest parser code for haproxy commands generates macros the vtest
+parser code for varnish cache has no knowledge of. This line prevents vtest from
+failing in such cases. As a "cli" macro automatically generated, this
+"feature ignore_unknown_macro" is mandatory for each VTC file for haproxy.
+
+To make vtest capable of testing haproxy, two new VTC commands have been
+implemented: "haproxy" and "syslog". "haproxy" is used to start haproxy process.
+"syslog" is used to start syslog servers (at this time, only used by haproxy).
+
+As haproxy cannot work without configuration file, a VTC file for haproxy must
+embed the configuration files contents for the haproxy instances it declares.
+This may be done using the following intuitive syntax construction: -conf {...}.
+Here -conf is an argument of "haproxy" VTC command to declare the configuration
+file of the haproxy instances it also declares (see "Basic HAProxy test" VTC file
+below).
+
+As for varnish VTC files, the parser of VTC files for haproxy automatically
+generates macros for the declared frontends to be reused by the clients later
+in the script, so after having written the "haproxy" command sections.
+The syntax "fd@${my_frontend_fd_name}" must be used to bind the frontend
+listeners to localhost address and random ports (see "Environment variables"
+section of haproxy documentation). This is mandatory.
+
+Each time the haproxy command parser finds a "fd@${xyz}" string in a 'ABC'
+"haproxy" command section, it generates three macros: 'ABC_xyz_addr', 'ABC_xyz_port'
+and 'ABC_xyz_sock', with 'ABC_xyz_sock' being resolved as 'ABC_xyz_addr
+ABC_xyz_port' typically used by clients -connect parameter.
+
+Each haproxy instance works in their own temporary working directories located
+at '/tmp/vtc.<varnitest PID>.XXXXXXXX/<haproxy_instance_name>' (with XXXXXXXX
+a random 8 digits hexadecimal integer. This is in this temporary directory that
+the configuration file is temporarily written.
+
+A 'stats.sock' UNIX socket is also created in this directory. There is no need
+to declare such stats sockets in the -conf {...} section. The name of the parent
+directory of the haproxy instances working directories is stored in 'tmpdir'. In
+fact this is the working directory of the current vtest process.
+
+There also exists 'testdir' macro which is the parent directory of the VTC file.
+It may be useful to use other files located in the same directory than the current
+VTC file.
+
+
+
+VTC file examples
+-----------------
+
+The following first VTC file is a real regression test case file for a bug which has
+been fixed by 84c844e commit. We declare a basic configuration for a 'h1' haproxy
+instance.

+The following example illustrate how to run a basic HTTP transaction between 'c1'
+client and 's1' server with 'http1' as haproxy frontend. This frontend listen
+on TCP socket with 'my_frontend_fd' as file descriptor.
+
+ # Mandatory line
+ varnishtest "Basic HAProxy test"
+
+ # As some macros for haproxy are used in this file, this line is mandatory.
+ feature ignore_unknown_macro
+
+ server s1 {
+ rxreq
+ txresp -body "s1 >>> Hello world!"
+ } -start
+
+ haproxy h1 -conf {
+ # Configuration file of 'h1' haproxy instance.
+ defaults
+ mode http
+ timeout connect 5s
+ timeout server 30s
+ timeout client 30s
+
+ backend be1
+ # declare 'srv1' server to point to 's1' server instance declare above.
+ server srv1 ${s1_addr}:${s1_port}
+
+ frontend http1
+ use_backend be1
+ bind "fd@${my_frontend_fd}"
+ } -start
+
+ client c1 -connect ${h1_my_frontend_fd_sock} {
+ txreq -url "/"
+ rxresp
+ expect resp.status == 200
+ expect resp.body == "s1 >>> Hello world!"
+ } -run
+
+
+It is possible to shorten the previous VTC file haproxy command section as follows:
+
+ haproxy h1 -conf {
+ # Configuration file of 'h1' haproxy instance.
+ defaults
+ mode http
+ timeout connect 5s
+ timeout server 30s
+ timeout client 30s
+ }
+
+In this latter example, "backend" and "frontend" sections are automatically
+generated depending on the declarations of server instances.
+
+
+Another interesting real regression test case is the following: we declare one
+server 's1', a syslog server 'Slg_1' and a basic haproxy configuration for 'h1'
+haproxy instance. Here we want to check that the syslog message are correctly
+formatted thanks to "expect" "syslog" command (see syslog Slg_1 {...} command)
+below.

+ # BUG/MINOR: log: pin the front connection when front ip/ports are logged
+ #
+ # Mathias Weiersmueller reported an interesting issue with logs which Lukas
+ # diagnosed as dating back from commit 9b061e332 (1.5-dev9). When front
+ # connection information (ip, port) are logged in TCP mode and the log is
+ # emitted at the end of the connection (eg: because %B or any log tag
+ # requiring LW_BYTES is set), the log is emitted after the connection is
+ # closed, so the address and ports cannot be retrieved anymore.
+ #
+ # It could be argued that we'd make a special case of these to immediately
+ # retrieve the source and destination addresses from the connection, but it
+ # seems cleaner to simply pin the front connection, marking it "tracked" by
+ # adding the LW_XPRT flag to mention that we'll need some of these elements
+ # at the last moment. Only LW_FRTIP and LW_CLIP are affected. Note that after
+ # this change, LW_FRTIP could simply be removed as it's not used anywhere.
+
+ # Note that the problem doesn't happen when using %[src] or %[dst] since
+ # all sample expressions set LW_XPRT.
