A reg test has been added to ensure the evaluation of http-after-responses rules
is functionnal for all kind of responses (server, applet and internal
responses).
2 reg tests have been added to ensure the HTTP return action is functionnal. A
reg test is about returning error files. The other one is about returning
default responses and responses based on string or file payloads.
With this new reg test we ensure the strict rewriting mode of HTTP rules is
functional. The mode is tested for request and response rules. The default mode
(strict), the swtich off and the reset on new ruleset are tested for both.
First, concat() is a converter, not a sample fetch. So use str() sample fetch
with no string and call concat on it. Then, the argument of the set-uri rule
must be a log format string. So it must be inside %[] to be evaluated.
In Travis build https://travis-ci.com/haproxy/haproxy/jobs/195477767 we
can see that OSX tends to pad zeroes at a different position than Linux
in compact IPv6 addresses, resulting in a failure in the checks which
were developped on Linux. This patch uses [0:]* in holes and [0:]+ at the
end of addresses to allow the different variants. It will unfortunately
also accept impossible addresses but there is no reason that we have to
care about for such crap to be emitted.
Some reg tests and their dependencies have been renamed. They may be
referenced by the .vtc files. So, this patch modifies also the references
to these dependencies.
This patch replaces LEVEL variable by REGTESTS_TYPES variable which is more
mnemonic and human readable. It is uses as a filter to run the reg tests scripts
where a commented #REGTEST_TYPE may be defined to designate their types.
Running the following command:
$ REGTESTS_TYPES=slow,default
will start all the reg tests where REGTEST_TYPE is defines as 'slow' or 'default'.
Note that 'default' is also the default value of REGTEST_TYPE when not specified
dedicated to run all the current h*.vtc files. When REGTESTS_TYPES is not specified
there is no filter at all. All the tests are run.
This patches also defines REGTEST_TYPE with 'slow' value for all the s*.vtc files,
'bug' value for al the b*.vtc files, 'broken' value for all the k*.vtc files.
Because HAProxy may decide to close 301 responses, as others internal responses,
it is safer to use a different client for these requests. This is not the
purpose of this test to verify the keep-alive in such cases.
These ones are not needed anymore since commit 97aaa67 ("MINOR: mux-h2:
only increase the connection window with the first update"). The tests
should now be more reliable. It might be worth simply removing all the
explicit handshake though it doesn't hurt and still serves as documentation.
Varnishtest is not happy to see the window update come before the
settings ACK, as by default it expects exactly tx/rx/txack/rxack.
One workaround could consist in making haproxy send the WU after
the settings ACK but this would be a real hack as the preface is
already finished when sending this ack. Instead, let's make the
initial sequence explicit in the tests.
fix http-rules/h00000.vtc / http-rules/h00000.vtc as both 'bodylen' and
'body' are specified, these settings conflict with each other as they
both generate/present the body to send.
The HTTP rules test now runs an H1 and an H2 client. Since the H2 one
requires the "proto" directive on the bind line, a new file has been
created requiring version 1.9 and the previous one was marked as usable
below 1.9 so that it's skipped by default but still usable when testing
backports.
There is always a risk of breaking HTTP processing when performing certain
code changes. This test modifies a request's start line, uses variables,
adds and modifies headers, interleaves them with the start-line changes,
and makes use of different header formats involving duplicated names,
duplicated values, empty fields and spaces around values. These operations
are performed both in the frontend and in the backend, for both the request
and the response. A CRC is computed on the concatenation of all the values,
and the concatenations are sent as individual header fields as well to help
debugging when the test fails.
The test reliably works since 1.6, implying that the HTTP processing did
not change. It currently fails on HTX.
