Reijo Tomperi 89fd5bacf9 Fix #2849, False positive: memory leak (using question mark operator)
http://sourceforge.net/apps/trac/cppcheck/ticket/2849

Simplify { ; { ; } } into { ; }
Removed one memleak test which should be redundant now as question marks
should not get into memleak check.

Robert Reif a2938b7212 fix 2011-04-28 19:08:18 -04:00
Kimmo Varis c7d99fe9a7 Remove ErrorLogger::reportStatus() method.
The ErrorLogger::reportStatus() is not lib code interface. The CLI
code does the looping through file list and gives one file at a
time for the core code. Hence lib has no any idea about the
progress and it can't provide such information.

Also the recent commit (6d858b6) caused a GUI build failure by
adding CLI code dependency to GUI. Which is big no-no.

This is admittedly a hack. But it allow us to build all modules
again.

Zachary Blair 46645ab327 Fixed #2722 (new check: statement that is always true (strcmp)) 2011-04-25 22:45:27 -07:00
Kimmo Varis f240574107 Modify the Cppcheck class to check one file at a time.
Unify usage and API of CppCheck class. Allow only one file checked
at a time, instead of list of files. Clients can then handle file
lists more naturally and as they see fit. Also clients have better
knowledge of how checking status should be handled.

The single-threaded CLI checking was only one using the file list.
Other clients were giving files (to list) one file at a time.
