Review request for KDevelop.


Changes
-------

Added test file.  Current HEAD will segfault when importing this.


Bugs: 358454
    http://bugs.kde.org/show_bug.cgi?id=358454


Repository: kdevelop


Description
-------

In projectmanagers/cmake/cmakeimportjsonjob.cpp, there's a regular expression that matches 'add_test' lines from CTestTestfile.cmake files, but it stops reading at the first ) character:

`const QRegularExpression rx("add_test *\((.+?) (.*?)\)");`

If the argument list for the add_test line contains brackets, for instance:

add_test(some-test "/some/path" "(foo)" "bar")

...then this causes a segfault a few lines further down - the second rx capture is not a well-formed argument list.

This patch changes the regexp to only stop when ) is at the end of the line:

`const QRegularExpression rx("add_test *\((.+?) (.*?)\) *$");`

It also allows for spaces between the ')' and the end of the line, to be consistent with allowing extra spacing earlier on after add_test.  I'm not sure if this matters in practice but is harmless enough.


Diffs
-----

  projectmanagers/cmake/cmakeimportjsonjob.cpp 0502be7 

Diff: https://git.reviewboard.kde.org/r/126931/diff/


Testing
-------

It can now import CTestTestfile.cmake files from my projects without crashing.  I haven't tested it with other people's cmake build trees.


File Attachments (updated)
----------------

This will cause a seg fault in importTestSuites
