<p class="MsoNormal">Hi Daniel,<br>
<br>
I’ve looked at the project in a bit more detail and here are some other general comments.<br>
<br>
It is very desirable to allow CodeChecker to work with scan-build (the current one and/or the python rewrite). This would ensure that all projects that we can analyze now (on all platforms such as OS X and Windows) will be supported. We agree that certain parts
of current scan-build could be improved; however, getting a modular design will allow us to stage that process. Keeping code checker build interposition separate from the current scan-build would cause fragmentation between the users and developers. Is it
possible the integrate CodeChecker with scan-build?<o:p></o:p></p>

it is. I think the best would be to add an option to CodeChecker to be able to parse the new scan-build output directory.</span><o:p></o:p></p>
</div>

</div>
</blockquote>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<p class="MsoNormal">Just to clarify, it would only work with the "new scan-build" since CodeChecker takes the compilation database as input, correct?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><span style="color:#558ED5;mso-style-textfill-fill-color:#558ED5;mso-style-textfill-fill-alpha:100.0%">DK> CodeChecker can take the compilation db as the input and invoke clang even today (CodeChecker check -l compilation_db …), so in this
sense it works well together with scan-build.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#558ED5;mso-style-textfill-fill-color:#558ED5;mso-style-textfill-fill-alpha:100.0%">However we could implement an option to take the output directory of the new-scan build with the plist files as the input. This would
work better for projects that remove source files during build. <o:p></o:p></span></p>

with a million lines of code and with potentially thousands of analyzer reports. Imagine that you analyze and store many version of this project each with say 5000 reports (with bug path). Then let’s say you would like to see the new bugs and resolved bugs
between 2 such versions (which now became possible with the bug hashes), or you want to filter/order the results based on fault priority/file path. For these tasks you need a DB backend with indexing. Does that make sense?<o:p></o:p></span></p>

Suppression in code should be handled by the compiler/analyzer, hopefully, using a more familiar syntax. (We can discuss this separately later.)<br>

<p class="MsoNormal">I think we should discuss the design on a separate thread. I do not think it's a critical feature, so we could do this later. The main issue here is that I am not comfortable with recommending users a way for suppressing issues in code
until the greater community agrees upon the design for issue suppression and compiler support is implemented. Once these recommendations are made, the users assume that the format will be supported going forward.<o:p></o:p></p>
</div>
<p class="MsoNormal"><span style="color:#558ED5;mso-style-textfill-fill-color:#558ED5;mso-style-textfill-fill-alpha:100.0%">DK> Unfortunately clang-sa reports many false positives for our projects. We spend considerable amount of time analyzing these reports
selecting and marking false positives. Since the bug-hash format is still not stable, there is a risk that this invested work gets lost. So a stable in-code bug suppression would be very nice feature both for tidy and clang-sa, preferably according to a greater
community agreement as you suggest.<o:p></o:p></span></p>

<p class="MsoNormal">- What would it take for this to replace scan-build? Can scan-build be used instead of the interposition module you use? For example, can we control the build interposition method by some option and the bug tracking would be an add-on on
top of that? I suspect that your solution does not work on all platforms that scan-build currently supports (Mac and Windows come to mind). That is the main concern here. There are also projects that might not build with the type of interposition you use.
I am not sure if you are aware of the scan-build rewrite (in Python) effort, where all these issues were raised as well.<o:p></o:p></p>
