I have a GUI application that I am trying to determine what is being used and what isn't. I have a number of test suites that have to be run manually to test the user interface portions. Sometimes I run the same file a couple of times with "coverage.py run file_name -a" and do different actions each time to check different interface tools. I would expect that each time I ran with the -a argument, I could only increase the code covered line count by coverage.py (at least unless new files are pulled in). However, sometimes it gives lower code coverage after an additional run - what could be causing this?
I am not editing source between runs and no new files are being pulled in as far as I can tell. I am using coverage.py version 3.5.1.
That sounds odd indeed. If you can provide source code and a list of steps to reproduce the problem, I'd like to take a look at it: you can create a ticket for it here: https://bitbucket.org/ned/coveragepy/issues

I am trying to measure coverage with racket cover
https://docs.racket-lang.org/cover/basics.html
like this
raco cover hello.rkt
However, if I run it more than once, it overwrites what is in the coverage directory instead of adding to it. If I do something like
raco cover hello.rkt
raco cover bye.rkt
the two html reports specific to these rkt files (coverage/hello.html and coverage/bye.html) remain intact, coverage/index.html will only have bye.rkt in it. Also I guess if they share a library, I'll only get coverage info for that library from the last run.
Does anybody have a way to combine two coverage reports from two different executions?
I am trying to separate out internal and external documentation using the doxygen constructs of cond; but i just cant seem to get get it working. I would essentially like to exclude some files completely and not conditionally. Regardless of where i add the tag (before include, before header guards etc) , the files and source both show up.
What i have tried in vain is to take the test file from doxegen repo for
conditional test and add it to the project.
Steps to reproduce [Linux]
create a new directory.
copy paste the above file (had to rename it to .h as .c was passed over?).
generate dummy config via doxygen -g.
update Doxyfile ENABLED_SECTION = COND_ENABLED.
Run doxygen.
check html/index.html
This however is still visible in the html documentation it generates for the project. I have set the ENABLED_SECTION variable with other values , but cond_enabled function still shows up. Running the testing directory of the project (doxygen) it passes. So i am lost.
Any suggestions?
Tried with latest version 1.8.14.
Thanks!
Regarding the \cond problems (not an answer directly to the real problem you face, I think, but to long for a comment).
The mentioned file is used in the, limited, testing doxygen can do / does and the first lines contain some instructions on what to do. Furthermore there is a default Doxyfile with the tests in use. It is hard to run a separate test outside the doxygen build tree.
Regarding the remark "Running the testing directory of the project (doxygen) it passes." This is correct, here, at the moment, only testing is done against the XML output and the generated output is compared to a once created version of the XML output. No tests are done, at the moment, in respect to HTML or PDF / LaTeX. Recently the test framework has been slightly extended so in the future this should be possible (compare the xhtml and tex output, but some work has still to be done here).
The version of the parser sees the \cond in the first line (normal C comment) as a doxygen command and skips everything till the first \endcond (your friend in these cases is always doxygen -d preprocessor). I think that removing / modifying the first line will result in an already better result. There is however another hiccup for e.g. HTML output. As the function cond_enabled is not documented and EXPAND_ALL is not set to YES the function will not appear in the documentation. So best is also to add a line of documentation with the function cond_enabled.
Regarding the seen HTML problems I modified the the relevant test in doxygen slightly and pushed a proposed patch to github (pull request 714, https://github.com/doxygen/doxygen/pull/714).
Note: the problem of skipping the \cond in normal C comment is quite a bit harder to implement (seen the logical complexity of the doxygen code in pre.l and commentcnv.l.
EDIT: 2018/06/10: The push request has been integrated in the master version on github.
So I noticed, while answering this question, that the one who asked the question appears to be a javascript developer. And as the code I wrote in haskell is easy enough, I thought I give haste a try and try to compile it to javascript.
So, I downloaded the Windows binary package of haste (why does the .msi require a reboot?!!?), added it to my path, issued haste-cabal update and haste-cabal install split and after a bit of reading the output of hastec --help, I issued:
PS E:\h\stackoverflow> hastec -o hexagon.js --pretty-print hexagon.hs
as my best guess on how to get the output I am looking for.
Opposite to my expectation, haste output was this:
hastec.exe: user error (shell expression failed in readModule: Data.Binary.Get.runGet at position 8: not enough bytes)
So, my question: What do I have to do to get a java script source file?
Is it possible that you have an old version of Haste lying around, or have intermediate files (.jsmod, for instance) from a different version of the compiler in your source directory? This sounds like the (quite unhelpful) error message Haste produces when it runs into a corrupted intermediate file.
Check that the version of the binary you're calling is what you expect (hastec --version). Then, try getting rid of all intermediate files in the directory as well as any files in %USERPROFILE%\AppData\Roaming\haste, reinstalling split, and recompiling with the -fforce-recomp flag. You should also add a main function, so that Haste has an entry point to your program from which to start linking. If all you want to do is to make some Haskell function available to external JavaScript, you can use the export foreign function interface:
{-# LANGUAGE OverloadedStrings #-}
module Main where
import Haste.Foreign
import Hexagon
main = export "picture" Hexagon.picture
You will probably also want to compile your program with the --onexec flag, to make sure that main runs and exports picture immediately when loaded, and not on page load which is the default:
> hastec -o hexagon.js --pretty-print --onexec hexagon.hs
After doing this, any code included after hexagon.js will be able to call e.g. Haste.picture(5); in order to produce a picture of size 5.
(Re: MSI installer requiring a reboot, this is required since it adds the Haste binaries to your %PATH%, which does not take effect immediately. I assume that a re-login would be enough to make it take effect, however.)
My problem is as described. My script downloads files through an external call to cmd (using the system function and then .NET to make keypresses). The issue is that when it tries to fopen these files I downloaded (filenames from a text file I write as I download), it doesn't find them, causing an error. When I run the script again after seeing it fail, it works but only up to the point where it's trying to download/call new files again, where it runs into the same problem.
Are new files downloaded during when a script is running somehow not visible to the search path? Because the folder is most definitely in my search path (seeing as it works outside of during-script downloads). It's not that it isn't getting the files fast enough either, cause they appear in my folder almost instantly, and I've tried a delay to allow for it to recognize it, but that didn't work either.
I'm not sure if it's important to note that the script calls an external function which tries to read the files from the .txt list I create in the main script.
Any ideas?
The script to download the files looks like so:
NET.addAssembly('System.Windows.Forms');
sendkey = #(strkey) System.Windows.Forms.SendKeys.SendWait(strkey);
system('start cygwinbatch.bat')
pause(.1)
sendkey(callStr1)
sendkey('{ENTER}')
pause(.1)
sendkey(callStr2)
sendkey('{ENTER}')
pause(.1)
sendkey('exit')
pause(2)
sendkey('{ENTER}')
But that is not the main reason I am asking: I am confident that the downloads are occurring when the script calls them, because I see them appearing in my folder as it called. I am more confused as to why MATLAB doesn't seem to know they are there while the script is running, and I have to stop it and run it again for it to recognize the ones I've downloaded already.
Thank you,
Aaron
The answer here is probably to run the 'rehash' function. Matlab does not look for new files while executing an operation, and in some environments misses new files even during interactive activity.
Running the rehash function forces Matlab to search through its full path and determine if there are any new files.
I've never tried to run rehash in the middle of an operation though. ...
My guess is that the MATLAB interpreter is trying to look ahead and is throwing errors based on a snapshot of what the filesystem looked like before the files were downloaded. Do you get different behavior if you run it one line at a time using F9? If that's the case then you may be able to prevent the interpreter from looking ahead by using eval().
I have written a large code (a calculator program) about 220,000 line of code and more in my base implementation file. The program build and run well, but whenever it comes to execute the codes from specific line number and further, the program stops, and gives a run time error. There is no problem with the code, I have tried it in smaller scale, (I mean deleting some lines) when it become smaller it runs ok.
My question here is this, does the Xcode have limitation in capacity of each file when running?
And if the answer is NO, so what should I do?
