In cherrypy.lib.static.py there is a method:
serve_file(path, content_type=None, disposition=None, name=None)
where the argument "path" must be a real file (absolute path). Is there something similar to serve any Python file object?
From studying http://www.cherrypy.org/browser/trunk/cherrypy/lib/static.py I'd have to say, no: the serve_file function is "monolithic", and does its own bodyfile = open(path, 'rb'), nor does there seem to be any alternative way. Pity, as it would be easy to refactor the function and add another e.g. serve_open_file to cover your case, having both delegate to an internal function for the "hard" logic such as multipart/byteranges serving. May be worth your while to open a feature request ("enhancement ticket") on cherrypy.org -- may not be a killer feature but I can see use cases, and implementing it wouldn't be hard for the cherrypy people (visit their site and follow the instructions on the page to "log in" to it).
As long as your file or file-like object is iterable, just return it from your handler function instead of a string.
Update:
To serve it as a download, set the Content-Type and Content-Disposition headers like so:
cherrypy.response.headers["Content-Type"] = "application/x-download"
cd = 'attachment; filename="%s"' % name
cherrypy.response.headers["Content-Disposition"] = cd
Or, use the serve_fileobj function in recent versions of cherrypy/lib/static.py, which does this for you and more.
Taking a new look at http://www.cherrypy.org/browser/trunk/cherrypy/lib/static.py, it looks like serve_fileobj does exactly what you want.
Edit: I've tried this now, and it only renders the file contents to the screen, rather than allowing the file to be downloaded.

I'm having an issue using the OneDrive for Business - List files in folder action.
I'm setting the path of the action to be a parameter received from a previous step via http request.
The value of the path is for example - /Clients/ER/EDI/ERGL/Source
When I hard code the path by selecting it in the OneDrive action, its value at runtime is
"datasets/default/folders/01RODCPVEAQQCC4IDDRBF3JHJW2GR43CXZ" and at design time it is set to
"path":
/datasets/default/folders/#{encodeURIComponent(encodeURIComponent('01RODCPVEAQQCC4IDDRBF3JHJW2GR43CXZ'))}
However, when I try and set the path via parameter, which at design time looks like this
"path":
/datasets/default/folders/#{encodeURIComponent(encodeURIComponent(triggerBody()?['Source']))}"
and is at run time - /datasets/default/folders/%252FClients%252FER%252FEDI%252FERGL%252FSource
it does not work. I'm obviously missing something here, with encoding the path parameter? Any suggestions?
Thanks,
Actually you get the true path, it's just in a encode format. You could find the example , the encodeUriComponent will return the URI-encoded string with escape characters.
So you could decode what you get with this expression:
decodeUriComponent(decodeUriComponent('%252FClients%252FER%252FEDI%252FERGL%252FSource'))
Then you will get the absolute path.
Hope this could help you, if you still have other questions, please let me know.
I'm trying to Create a file and append all the content being calculated into that file, but when I run the script the very last iteration is written inside the file and nothing else.
My code is on pastebin, it's too long, and I feel like you would have to see exactly how the iteration is happening.
Try to summarize it, Go through an array of model numbers, if the model number matches call the function that calculates that MAC_ADDRESS, when done calculating store all the content inside a the file.
I have tried two possible routes and both have failed, giving the same result. There is no error in the code (it runs) but it just doesn't store the content into the file properly there should be 97 different APs and it's storing only 1.
The difference between the first and second attempt,
1 attempt) I open/create file in the beginning of the script and close at the very end.
2 attempt) I open/create file and close per-iteration.
First Attempt:
https://pastebin.com/jCpLGMCK
#Beginning of code
File = open("All_Possibilities.txt", "a+")
#End of code
File.close()
Second Attempt:
https://pastebin.com/cVrXQaAT
#Per function
File = open("All_Possibilities.txt", "a+")
#per function
File.close()
If I'm not suppose to reference other websites, please let me know and I'll just paste the code in his post.
Rather than close(), please use with:
with open('All_Possibilities.txt', 'a') as file_out:
file_out.write('some text\n')
The documentation explains that you don't need + to append writes to a file.
You may want to add some debugging console print() statements, or use a debugger like pdb, to verify that the write() statement actually ran, and that the variable you were writing actually contained the text you thought it did.
You have several loops that could be a one-liner using readlines().
Please do this:
$ pip install flake8
$ flake8 *.py
That is, please run the flake8 lint utility against your source code,
and follow the advice that it offers you.
In particular, it would be much better to name your identifier file than to name it File.
The initial capital letter means something to humans reading your code -- it is
used when naming classes, rather than local variables. Good luck!
I'm using JMeter 2.6, and have the following setup for my test:
-
|-test.jmx
|-myschema.xsd
I've set up an XML Schema Assertion, and typed "myschema.xsd" in the File Name field. Unfortunately, this doesn't work:
HTTP Request
Output schema : error: line=1 col=114 schema_reference.4:
Failed to read schema document 'myschema.xsd', because
1) could not find the document;
2) the document could not be read;
3) the root element of the document is not <xsd:schema>.
I've tried adding several things to the path, including ${__P(user.dir)} (points to the home dir of the user) and ${__BeanShell(pwd())} (doesn't return anything). I got it working by giving the absolute path, but the script is supposed to be used by others, so that's no good.
I could make it use a property value defined in the command line, but I'd like to avoid it as well, for the same reason.
How can I correctly point the Assertion to the schema under these circumstances?
Looks like you have to in this situation
validate your xml against xsd manually: simply use corresponding java code from e.g. BeanShell Assertion or BeanShell PostProcessor;
here is a pretty nice solution: https://stackoverflow.com/a/16054/993246 (as well you can use any other you want for this);
dig into jmeter's sources, amend XML Schema file obtaining to support variables in path (File Name field) - like CSV Data Set Config does;
but the previous way seems to be much easier;
run your jmeter test-scenario from shell-script or ant-task which will first copy your xsd to jmeter's /bin dir before script execution - at least XML Schema Assertion can be used "as is".
Perhaps if you will find any other/better - please share it.
Hope this helps.
Summary: in the end I've used http://path.to.schema/myschema.xsd as the File Name parameter in the Assertion.
Explanation: following Alies Belik's advice, I've found that the code for setting up the schema looks something like this:
DocumentBuilderFactory parserFactory = DocumentBuilderFactory.newInstance();
...
parserFactory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource", xsdFileName);
where xsdFileName is a string (the attribute string is actually a constant, I inlined it for readability).
According to e.g. this page, the attribute, when in the form a String, is interpreted as an URI - which includes HTTP URLs. Since I already have the schema accessible through HTTP, I've opted for this solution.
Add the 'myschema.xsd' to the \bin directory of your apache-jmeter next to the 'ApacheJMeter.jar' or set the 'File Name' from the 'XML Schema Assertion' to your 'myschema.xsd' from this starting point.
E.g.
JMeter: C:\Users\username\programs\apache-jmeter-2.13\bin\ApacheJMeter.jar
Schema: C:\Users\username\workspace\yourTest\schema\myschema.xsd
File Name: ..\\..\\..\workspace\yourTest\schema\myschema.xsd
I've got question about program architecture.
Say you've got 100 different log files with different formats and you need to parse and put that info into an SQL database.
My view of it is like:
use general config file like:
program1->name1("apache",/var/log/apache.log) (modulename,path to logfile1)
program2->name2("exim",/var/log/exim.log) (modulename,path to logfile2)
....
sqldb->configuration
use something like a module (1 file per program) type1.module (regexp, logstructure(somevariables), sql(tables and functions))
fork or thread processes (don't know what is better on Linux now) for different programs.
So question is, is my view of this correct? I should use one module per program (web/MTA/iptablat)
or there is some better way? I think some regexps would be the same, like date/time/ip/url. What to do with that? Or what have I missed?
example: mta exim4 mainlog
2011-04-28 13:16:24 1QFOGm-0005nQ-Ig
<= exim#mydomain.org.ua** H=localhost
(exim.mydomain.org.ua)
[127.0.0.1]:51127 I=[127.0.0.1]:465
P=esmtpsa
X=TLS1.0:DHE_RSA_AES_256_CBC_SHA1:32
CV=no A=plain_server:spam S=763
id=1303985784.4db93e788cb5c#mydomain.org.ua T="test" from
<exim#exim.mydomain.org.ua> for
test#domain.ua
everything that is bold is already parsed and will be putted into sqldb.incoming table. now im having structure in perl to hold every parsed variable like $exim->{timstamp} or $exim->{host}->{ip}
my program will do something like tail -f /file and parse it line by line
Flexability: let say i want to add supprot to apache server (just timestamp userip and file downloaded). all i need to know what logfile to parse, what regexp shoud be and what sql structure should be. So im planning to have this like a module. just fork or thread main process with parameters(logfile,filetype). Maybe further i would add some options what not to parse (maybe some log level is low and you just dont see mutch there)
I would do it like this:
Create a config file that is formatted like this: appname:logpath:logformatname
Create a collection of Perl class that inherit from a base parser class.
Write a script which loads the config file and then loops over its contents, passing each iteration to its appropriate handler object.
If you want an example of steps 1 and 2, we have one on our project. See MT::FileMgr and MT::FileMgr::* here.
The log-monitoring tool wots could do a lot of the heavy lifting for you here. It runs as a daemon, watching as many log files as you could want, running any combination of perl regexes over them and executing something when matches are found.
I would be inclined to modify wots itself (which its licence freely allows) to support a database write method - have a look at its existing handle_* methods.
Most of the hard work has already been done for you, and you can tackle the interesting bits.
I think File::Tail is a nice fit.
You can make an array of File::Tail objects and poll them with select like this:
while (1) {
($nfound,$timeleft,#pending)=
File::Tail::select(undef,undef,undef,$timeout,#files);
unless ($nfound) {
# timeout - do something else here, if you need to
} else {
foreach (#pending) {
# here you can handle log messages depending on filename
print $_->{"input"}." (".localtime(time).") ".$_->read;
}
(from perl File::Tail doc)
I’m writing a cucumber test where I want to get the HTML in an element.
For example:
within 'table' do
# this works
find('//tr[2]//td[7]').text.should == "these are the comments"
# I want something like this (there is no "html" method)
find('//tr[2]//td[7]').html.should == "these are the <b>comments</b>"
end
Anyone know how to do this?
You can call HTML DOM innerHTML Property:
find('//tr[2]//td[7]')['innerHTML']
Should work for any browser or driver.
You can check all available properties on w3schools
This post is old, but I think I found a way if you still need this.
To access the Nokogiri node from the Capybara element (using Capybara 1.0.0beta1, Nokogiri 1.4.4) try this:
elem = find('//tr[2]//td[10]')
node = elem.native
#This will give you a Nokogiri XML element
node.children[1].attributes["href"].value.should == "these are the <b>comments</b>"
The last part may vary for you, but you should be able to find the HTML somewhere in that node variable
In my environment, find returns a Capybara::Element - that responds to the :native method as Eric Hu mentioned above, which returns a Selenium::WebDriver::Element (for me). Then :text gets the contents, so it could be as simple as:
results = find(:xpath, "//td[#id='#{cell_id}']")
contents = results.native.text
if you're looking for the contents of a table cell. There's no content, inner_html, inner_text, or node methods on a Capybara::Element. Assuming people aren't just making things up, perhaps you get something different back from find depending on what else you have loaded with Capybara.
Looks like you can do (node).native.inner_html to get the HTML content, for example with HTML like this:
<div><strong>Some</strong> HTML</div>
You could do the following:
find('div').native.inner_html
=> '<strong>Some</strong> HTML'
I ran into the same issue as Cyril Duchon-Doris, and per https://github.com/teampoltergeist/poltergeist/issues/629 the way to access the HTML of an Capybara::Poltergeist::Node is via the outerHTML property, e.g.:
find('//tr[2]//td[7]')['outerHTML']
Most of the other answers work only in Racktest (as they use Racktest-specific features).
If your driver supports javascript evaluation (like Selenium) you can use innerHTML :
html = page.evaluate_script("document.getElementById('my_id').innerHTML")
If you're using the Poltergeist driver, these methods will allow you to inspect what matches:
http://www.rubydoc.info/gems/poltergeist/1.5.1/Capybara/Poltergeist/Node
For example:
page.find('[name="form-field"]').native.value == 'something'
try calling find('//tr[2]//td[10]').node on it to get at the actual nokogiri object
Well, Capybara uses Nokogiri to parse, so this page might be appropriate:
http://nokogiri.org/Nokogiri/XML/Node.html
I believe content is the method you are looking for.
You could also switch to capybara-ui and do the following:
# define your widget, in this case in your role
class User < Capybara::UI::Role
widget :seventh_cell, [:xpath, '//tr[2]//td[7]']
end
# then in your tests
role = User.new
expect(role.widget(:seventh_cell).html).to eq(<h1>My html</h1>)
