Hi Felix,
Hi
I agree with sebb, patch is interesting.
But it clearly needs to be documented (I think many users don't know about
this feature which is really interesting) as long as code, reading patch
first it wasn't clear for me what was intended.
I have added documentation to the patch and found two other things, that I
changed
in the same bug-entry.
The random order of applying the matchers, seems a bit strange, so I
sorted the matchers
first by their length and if the matchers are the same length, then by the
name of their keys. So
the set
{'domain': 'example.com', 'server': 'www', 'regex': 'w.*' }
would be applied in the order ['domain', 'regex', 'server'] since 'domain'
has the longest matcher and
'regex' comes before 'server' alphabetically (matchers are both the same
length).
Isn't it better to order by longest value or regexp ?
www is more specific than w.*
So would be :
domain, server , regex
Or the code could try to match every variable and select the one that
produces the longest match.
But rather than try and sort the regexes, which is always going to be
tricky to do "correctly" (whatever that means), maybe the user should
be given control of the matching order.
For example, it is probably possible to match by order of appearance.
It would certainly be possible to match the variables in sorted order by name.
This would be a bit more awkard to use than changing the order of
variable definitions.
I just wanted to give a simple algorithm for ordering, which I think is
better than random ordering.
Correctness will be hard to implement, when everyone has a different
view on the correct ordering.
I had thought of giving more control to the user by appending the
variable names with something to sort by.
For example extending the above example with variable names ['domain',
'server', 'regex'] the names could be
changed to ['domain_3', 'server_1', 'regex_2'] to impose replacement in
the order ['server', 'regex', 'domain'].
But what should we do with the suffix '_\d+'? (A prefix could be used, too)
We could look for a specially named variable like '_regex_order' which
could have a comma separated list of
the variable names in the wished order.
The longer I think about it, the more I am inclined to take the simple
ordering algorithm of length and then name. One can
always make any regex longer by adding useless junk like
'(?:WILLNOTBEFOUNDANYWAY)?' and in such a way influence
the order.
Felix
If no one objects, I will submit it next week.

Felix
Thanks for contributing

I've attached a jmeter project file and a html file that
demonstrates the
issue. In order to reproduce:
1. Load up xml-bug-test.jmx in jmeter.
2. Start the proxy (recorder)
3. Place xml-bug-test.html on a webserver somewhere (if on
localhost, do
not
forget to remove localhost from proxy exclusion if applicable)
4. Navigate with a browser to this file (using the proxy)
5. Click both buttons in order.
I could not post to a html file, hence the "test 2" button will
post to
Google. The page that loads has an error, but it still records the
post
request which is what we want to see.
I also discovered that when I was using a "get" request instead
(I've
made
that "test 1") then it doesn't match the first character (%). I
think
this
is related.
The project has a user defined variable called "TEST" with a value
os
".*",
I've ticked the box
To see the results, in the recording controller the last two
requests
contain a parameter with these values:
Test 1: %${TEST}
Test 2: <${TEST}>
Both should be just ${TEST} I believe.
In the current implementation the regex will be matched against a
pattern
which looks like
\b(YOUR_VALUE)\b
As % and < are boundary characters they are excluded from you
pattern.
This is deliberate.
There were problems previously as partial values were being
unexpectedly matched.
See https://issues.apache.org/bugzilla/show_bug.cgi?id=52678
I thougt so. Maybe, that would have been helped by adding more
documentation, but then it is regex...
I would consider this a bug, or at least documentation could be a
bit
more
concise.
Patches welcome.
A patch was attached :)
I meant that we would welcome a patch for the documentation.
Or at least some indication of where the documentation needs to be
updated to clarify the current behaviour.
I will look into that.
Thanks.
What is your opinion on the option to detect parens and modify the regex
behavior?
Looks good to me.
The parens are very unlikely to have been used in existing tests, so
the modified behaviour is unlikely to break anything.
But we should document it in the release notes just in case.
Felix
Attached is a patch against trunk, which checks the regex if it
starts
with
'(' and ends with ')' and uses the regex as given, instead of
building
its
own version.
Please use Bugzilla for patches; it's easier to keep track of them.
I have already done so yesterday shortly after sending my mail. It is
https://issues.apache.org/bugzilla/show_bug.cgi?id=57032
What is missing from the patch is documentation. If the feature as
such is
ok, then I would add that to the existing documentation.

Felix
Also, see notes below.

Hi,
I have an issue, which might well be a potential bug, where a
posted
value
is
not being matched by the Test Script Recorder's Regex Matching
functionality.
The request I'm recording has a post value containing XML (SAML
token to
be
exact) which I'd like to replace with a variable automatically.
What does the value look like?
Does it have multiple lines?
No, it did not have multiple lines. I did check if this was the
case, but
it
wasn't
For testing purposes I have configured a User Defined Variable
(called
TEST)
with a value of "(?s)^.*$", I've tried "^.*$" and ".*" as well (all
without
double
quotes).
Only ".*" replaces the content with this: <${TEST}>
That does not make sense.
".*" will match everything, including < and >, so the content would
become
${TEST}
I know. It doesn't really. Hence I think this might be a bug.
I've tried other expressions as well and I'm able to match anything
within
the
<> characters, but not those characters itself.
Again, that does not make sense.
The weird thing is, that inside the outer <> characters there are
other
<>
characters that are matched fine. It's just the first and last
character.
Does anyone else have experienced the same thing, or is this a
known
issue?
It is not a known issue, and may not even be an issue.
Or should I post this in the developer's mailing list?
No, the developers all follow this list.
Great, please see attachment for an example.
Cheers
