I'm using lcov to generate coverage reports. I have a tracefile (broker.info) with this content (relevant fragment shown):

$ lcov -r broker.info
...
[/var/lib/jenkins/jobs/ContextBroker-PreBuild-UnitTest/workspace/test/unittests/orionTypes/]
EntityTypeResponse_test.cpp                    | 100%    11| 100%   6|    -    0
...

[/var/lib/jenkins/jobs/ContextBroker-PreBuild-UnitTest/workspace/test/unittests/parse/]
CompoundValueNode_test.cpp                     | 100%    82| 100%  18|    -    0
...

[/var/lib/jenkins/jobs/ContextBroker-PreBuild-UnitTest/workspace/test/unittests/rest/]
OrionError_test.cpp                            |92.1%    38| 100%   6|    -    0
...

[/var/lib/jenkins/jobs/ContextBroker-PreBuild-UnitTest/workspace/test/unittests/serviceRoutines/]
badVerbAllFour_test.cpp                        | 100%    24| 100%   7|    -    0
...

I want to remove all the info corresponding to test/unittest files.

I have attemped to use the -r option which, according to man page is:

-r tracefile pattern --remove tracefile pattern Remove data from tracefile.

Use this switch if you want to remove coverage data for a particular set of files from a tracefile. Additional command line parameters will be interpreted as shell wildcard patterns (note that they may need to be escaped accordingly to prevent the shell from expanding them first). Every file entry in tracefile which matches at least one of those patterns will be removed.

The result of the remove operation will be written to stdout or the tracefile specified with -o.

Only one of -z, -c, -a, -e, -r, -l, --diff or --summary may be specified at a time.

Thus, I'm using

$ lcov -r broker.info 'test/unittests/*' -o broker.info2

As far as I understand test/unittest/* matches the files under test/unittest. However, it's not working (note Deleted 0 files below):

Reading tracefile broker.info
Deleted 0 files
Writing data to broker.info2
Summary coverage rate:
  lines......: 92.6% (58313 of 62978 lines)
  functions..: 96.0% (6451 of 6718 functions)
  branches...: no data found

I have tried also this variants (same result):

$ lcov -r broker.info "test/unittests/*" -o broker.info2
$ lcov -r broker.info "test/unittests/\*" -o broker.info2
$ lcov -r broker.info "test/unittests" -o broker.info2

So, maybe I'm doing something wrong?

I'm using lcov version 1.13 (just in case the data is relevant)

Thanks!

I have been testing another options and the following one seems to work, using the wildcard in the prefix also:

$ lcov -r broker.info "*/test/unittests/*" -o broker.info2

Maybe it is something new in version 1.13 because in version 1.11 it seems it works without wildcard in the prefix...

The below mentioned lcov command is working fine, even with wild characters (lcov 1.14):

lcov --remove meson-logs/coverage.info '/home/builduser/external/*' '/home/builduser/unittest/*' -o meson-logs/sourcecoverage.info
