We agree that certain parts of current scan-build could be improved; however, getting a modular design will allow us to stage that process.

However we designed it for the use case when you analyze a project 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.

My question is about whether it is possible to use the tool without a database. For example, a user may want to scan the project and see the results as a way of learning more about the static analyzer. Or a user might keep their project clean of the static analyzer issues and scan it from time to time. Basically, any workflow that scan-build supports right now would benefit from having a better report viewer, which code checker provides.</div><div><br class=""></div><div><blockquote type="cite" class=""><div class=""><div class="WordSection1" style="page: WordSection1; font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="color: red;" class=""><br class=""><o:p class=""></o:p></span></div><div class=""><div class=""><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="color: red;" class="">Setting up postgresql for a quick analysis is cumbersome,</span><o:p class=""></o:p></div></div><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="color: red;" class="">therefore we added sqlite support (based on earlier suggestion from Laszlo Nagy).</span><o:p class=""></o:p></div></div><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="color: red;" class=""> </span><o:p class=""></o:p></div></div><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="color: red;" class="">You can run the check and the server like this</span><o:p class=""></o:p></div></div><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-size: 10pt; font-family: 'Segoe UI', sans-serif; color: red;" class="">CodeChecker check -n test --sqlite -w /tmp/workspace -b "make"</span><o:p class=""></o:p></div></div><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-size: 10pt; font-family: 'Segoe UI', sans-serif; color: red;" class="">CodeChecker server --sqlite -w /tmp/workspace -v 6060 --not-host-only</span><o:p class=""></o:p></div></div><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="color: red;" class=""> </span><o:p class=""></o:p></div></div><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="color: red;" class="">So you can run this quickly without postgres config, suitable for basic usage.</span><o:p class=""></o:p></div></div><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><br class="">We’d need to integrate the automated tests into lit and add documentation.<br class=""><span style="color: red;" class="">DK> Sure, we will integrate auto-tests into lit.

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 class=""></o:p></span></div><div class=""><div class=""><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);" class=""> </span><o:p class=""></o:p></div></div><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""><br class="">All command line options should be compatible/make sense in the potential future world of whole project analysis.

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 class=""></o:p></div></div></div></div><div class=""><div class=""><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class=""> <o:p class=""></o:p></div></div></div></div><div class=""><div class=""><div class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;" class="">- Is licensing compatible?
