Dotcover.exe report tries to connect to raw.github.com

Hello Goran,

In order to create an HTML report, dotCover needs your source code files. It takes info about where the source code files can be found from PDB files loaded during the coverage analysis. Each PDB file contains local paths to the source files from which it was built. Also, PDB files can contain remote source servers addresses where source code files can be downloaded.

dotCover first tries to find the source code files locally. If it fails (e.g. if you try to create a coverage report not on the same machine where your project was built), it tries to find and download the source code files remotely.

In your case, it looks like PDB files contain "raw.github.com" as a remote source server address and you try to build an HTML report on a machine where there are no local source code files.

This behavior can't be changed now. In order to avoid access to the remote source server, you should build coverage reports on the same machine where you build the project.

In any case, access to a remote server shouldn't lead to hanging. Could you please send us more detailed log file? Please use the following command line keys:

/LogLevel=Verbose /LogFile=path_to_log_file

Ok, tried with the verbose log, and the process is not acutually hanging (but it seems so)

It looks like the report tries to download each source file of one dll from github, but since we dont have access to that from buildserver it fails.

What i am running:

D:\Tools\DotCover\dotCover.exe cover /TargetExecutable="D:\Tools\NUnit.org\nunit-console\nunit3-console.exe" /TargetArguments=".\VtDigitalCouponServiceBuild\VT.DigitalCouponService.Domain.UnitTests.dll" /Output="Snapshot1.dcvr" /TargetWorkingDir="d:\coveragetemp" /LogFile="d:\coveragetemp\coverage.log"

This works fine, next step is:

D:\Tools\DotCover\dotcover.exe report /Source=Snapshot1.dcvr /Output=CoverageReport.html /ReportType=html /LogFile="d:\coveragetemp\coverageReport3.log" /LogLevel=Verbose

This step tries to download each file of FakeItEasy. I tried to exclude the FakeItEasy dll from analyze (with parameter /Filters="-:FakeItEasy.*" but that didnt help.

What I would like is that the analyze is only done on any files that has pattern vt.* is that possible?

logfile looks like this:

.... continues looong time for each source file in FakeItEasy

....

I can send entire logfile if needed, please provide email adress in that case.

Hello Goran,

In order to exclude FakeItEasy.dll from the analysis please use the following filter with your "cover" command: /Filters=-:FakeItEasy (without ".*"). It should help to get rid of downloading source files.

Unfortunately, filtering based on source file names is not supported now. You can exclude code from the analysis using assembly names (without extensions), namespaces, class and method names and attribute names.

worked perfectly, thanks a million!!
