v6.19.0

❗❗❗ Backward incompatible changes ❗❗❗

• Fix JSON format of CodeChecker version subcommand (#3558)
  The output of the CodeChecker version -o json command wasn't a valid JSON format. From this release CodeChecker will provide a valid JSON output for this command.
  For more information see the documentation.
• Not allowing disabling modeling checkers in ClangSA (#3323)
  When a Clang Static Analyzer checker is disabled in CodeChecker, clang is invoked with the analyzer-disable-checker flag. This allows the user disabling core modeling checkers such as unix.DynamicMemoryModeling. This causes malfunctioning of depending checkers.
  From this release modeling and debug checkers (listed with clang -cc1 -analyzer-checker-help-developer) will not be listed and cannot be disabled through CodeChecker with the --enable and --disable flags.
  They can be enabled/disabled through the Clang Static Analyzer specific --saargs flag only.
• Change minimum supported node version (#3581, #3586)
  The minimum supported node version to build CodeChecker after this release is >=14.17.0.

⭐ New features

• Add print-steps option to CodeChecker cmd diff command (#3555)
  Without bug steps it is hard to understood the problem by a programmer. With this commit we will introduce a new option for the CodeChecker cmd diff command which can be used to print bug steps similar what we are doing at the CodeChecker parse command. This patch also solve the problem to print bug steps in HTML files for reports which comes from a CodeChecker server.
• Support yaml CodeChecker configuration files (#3602)
  Multiple subcommands have a --config option which allow the configuration from an explicit configuration file. The parameters in the config file will be emplaced as command line arguments. Previously we supported only JSON format but the limitation of this format is that we can't add comments in this file for example why we enabled/disabled a checker, why an option is important etc.
  From this release we will also support YAML format:

  analyzer:
    # Enable/disable checkers.
    - --enable=core.DivideZero

  For more information see the documentation.

💻 CLI / Server improvements / fixes

• Allow --file and skipfile option to be given together and analyze header file (#3616)
  The CodeChecker VSCodePlugin uses the --file parameter to analyze single files. Large projects load in their configuration using the --config parameter and if there is a -i skipfile given in the config, CodeChecker analyze call drops an error. From this release CodeChecker will allow -i skipfile and --file to be given together.
  Also if a header file is given to the --file option CodeChecker under the hood will try to figure out which source files are depends on the given header file and we will analyze these source files.
• Allow escaping : in run names with \: (#3536)
  In certain scenarios, the run name might contain a : character that does NOT separate a tag from a name. Commands such as server and cmd results accept : as a literal in the name, but cmd diff previously cut it as the "run tag" separator.
• Update allowed TLS versions (#3594)
  TLS1 and TLS1.1 were deprecated in RFC8996. From this release CodeChecker will enforce the newer TLS1.2 or TLS1.3.
• Fix HTML generation for CodeChecker cmd diff command (#3600)
  If the diff command result contained reports from multiple source files (e.g.: a.cpp + b.cpp) the CodeChecker cmd diff command in HTML format generated HTML files for each source file but inserted the same list of reports in all of the HTML files. From this release CodeChecker will insert only those reports to a generated HTML file which are really related to that file.
• Relative doc url to absolute file path (#3609)
  Convert relative doc_url value's to absolute file paths in the CodeChecker checkers output. This way other tools can open and view these documentation files easily.
• Fix html generation for report directory without plists (#3610)
  Fix HTML generation for report directory which doesn't contain any analyzer result (plist) file.

🎉 CodeChecker VSCode plugin

We are proud to announce the official release of CodeChecker VSCode plugin.

🌟 Main features

• Run CodeChecker analysis from the editor and see the results automatically.
• Re-analyze the current file when saved.
• Commands and build tasks for running CodeChecker as part of a build system.
• Browse through the found reports and show the reproduction steps directly in the code.
• Navigate between the reproduction steps.

💻 Trying It Out

1. Install CodeChecker version 6.18.2 or later and optionally add it to the PATH environment variable.
2. Install CodeChecker extension from the Visual Studio Marketplace, from Open VSX or download manually from Downloads.
3. Check the path to CodeChecker and set your preferred command-line arguments - see Configuring CodeChecker for more information.
4. Open your project, and run an analysis, or browse through the found reports!

v6.18.2

🐛 Analyze fixes

• Fix skipping reports (#3559).
  When a skip list was set, not only those reports were skipped that were included in the skipped files, but also those that had a bug path traversing a skipped file. This resulted in disappeared findings.
• Fix static HTML report files (#3570).
  It was not always possible to navigate in the static HTML files, when the bug path traversed multiple files.
• Remove bugprone-easily-swappable-parameters from sensitive profile (#3579).
  The checker warns for a bugprone coding style at function definitions. It is mostly useful for new code, where new functions are being defined. On the other hand, the checker required too many changes in legacy projects with non-matching coding style.

💻 CLI / Server fixes

• Fix suppressing bug on the server (#3563).
  When the report was in multiple lines, the source code comments in the code were not taken into consideration.
• Fix source line / file for remote reports (#3568).
  An exception was thrown at CodeChecker cmd diff when path trimming was used in the stored results.
• Fix storage of control points (#3576).
  Not all of the control points were stored to the server, because the plist format what the report converter produced and the plist parser expected was invalid. This way when an analyzer result file was stored to the server, bug path arrows were missing from the GUI.
• Escape values for v-html attributes (#3549).
  We are using v-html attribute on the UI side to dinamically rendering comments and analyzer commands. This can be very dangerous because it can easily lead to XSS vulnerabilities. To solve this problem the server will always return the escaped version of these values which can be safely rendered on the UI.
• Fix link in gerrit output (#3572).
  If CC_REPORT_URL is defined and gerrit format is used at CodeChecker parse or CodeChecker cmd diff commands, the output will contain the value of this environment variable wrapped inside quotes. When this output is sent to gerrit, it will convert URL links to HTML a tags. Unfortunately gerrit will think that the ending quote is part of the URL, so it will not remove it. This way the URL will be invalid.
• Change permission of stored analysis failure files (#3574).
  Change permission of the stored analysis failure zip files so only the current user/group will have access to this file.

For more information check the milestone.

v6.18.0

❗❗❗ Backward incompatible CLI change ❗❗❗

The JSON output of the CodeChecker parse command was not stable enough and the structure was very similar to the plist structure. Our plan is to support reading/parsing/storing of multiple analyzer output types not only plist but for example sarif format as well (http://docs.oasis-open.org/sarif/sarif/v2.0/csprd01/sarif-v2.0-csprd01.html). For this reason we changed the format of the JSON output of the CodeChecker parse and CodeChecker cmd diff command. The new format is described in #3519.

New features

For more information check the milestone.

v6.17.0

New features

Git blame integration (#3398, #3423, #3425, #3430)

With this feature it will be possible for a developer to check who modified the source line last where a CodeChecker error appears.

• If the project which was analyzed is a git repository CodeChecker store command will store blame information for every source files which are not stored yet.
• The GUI will have a button on the report detail view to show blame information alongside the source file.
• Hovering the mouse over a blame line, commit details will be shown in a pop-up window. Clicking on the hash will jump to the remote url of the repository and shows the commit which related to a blame line.

Cleanup plans (#3419)

Cleanup plans can be used to track progress of reports in your product. The conception is similar to the github Milestones.

You can do the following:

• Managing cleanup plans: you can create cleanup plans by clicking on the pencil icon at the Cleanup plan filter on the Reports page. A pop-up window will be opened where you can add, edit, close or remove existing cleanup plans.
• Add reports to a cleanup plan: you can add multiple reports to a cleanup plan on the Reports page or on the Report detail page by clicking to the Set cleanup plan button and selecting a cleanup plan.
  Note: you can remove reports from a cleanup plan the same way by clicking on the cleanup plan name.
• Filter reports by cleanup plans: you can filter reports by a cleanup plan by using the Cleanup plan filter on the Reports page. Using this filter with other filters (Detection status, Review status etc.) you will be able to filter active / resolved reports in you cleanup plan.

Local diff workflow support (#3388)

If you want to use CodeChecker in your project but you don't want to run a CodeChecker server and to fix every reports found by CodeChecker for the first time (legacy findings) with this feature you can do the following:

1. Analyze your project to a report directory as usual (e.g.: ./reports).
2. Create a baseline file from the reports which contains the legacy findings: CodeChecker parse ./reports -e baseline -o reports.baseline. Note: it is recommended to store this baseline file (reports.baseline) in your repository.
3. On source code changes after your project is re-analyzed use the CodeChecker diff command to get the new reports:
   CodeChecker cmd diff -b ./reports.baseline -n ./reports --new
4. On configuration changes (new checkers / options are enabled / disabled, new CodeChecker / clang version is used, etc.) re-generate the baseline file (step 1-2).

LeakSanitizer Parser (#3368, #3375)

The report-converter tool is extended with LeakSanitizer which is a run-time memory leak detector for C programs.

# Compile your program.
clang -fsanitize=address -g lsan.c

# Run your program and redirect the output to a file.
ASAN_OPTIONS=detect_leaks=1 ./a.out > lsan.output 2>&1

# Generate plist files from the output.
report-converter -t lsan -o ./lsan_results lsan.output

# Store reports.
CodeChecker store ./lsan_results -n lsan

For more information see.

Checker label (#3233, #3413, #3414, #3415, #3432)

Previously the properties of checkers (severity, profile, guideline) are read from several JSON files. The goal was to handle all these and future properties of checkers in a common manner. This new solution uses labels which can be added to checkers.

The collection of labels is found in config/labels directory. The goal of these labels is that you can enable or disable checkers by these labels.

# List checkers in "sensitive" profile.
CodeChecker checkers --label profile:sensitive

# List checkers in "HIGH" severity.
CodeChecker checkers --label severity:HIGH

# List checkers covering str34-c SEI-CERT rule.
CodeChecker checkers --label sei-cert:str-34-c

# List checkers covering all SEI-CERT rules.
CodeChecker checkers --label guideline:sei-cert

# List available profiles, guidelines and severities.
CodeChecker checkers --profile
CodeChecker checkers --guideline
CodeChecker checkers --severity

# List labels and their available values.
CodeChecker checkers --label
CodeChecker checkers --label severity

# Enable HIGH checkers during analysis.
CodeChecker analyze \
  ./compile_commands.json \
  -o ./reports
  -e severity:HIGH

Note: with this new feature we also added severity levels for pylint (#3414) and cppcheck (#3415) analyzers.

Add compilation database generator for Bazel (#3226, #3284).

CodeChecker was extended with a tool that can capture compilation database of a Bazel built product without actually performing compilation. For more information see.

Exporter/importer command for CodeChecker cmd (#3116)

New command line options are introduced (CodeChecker cmd export and CodeChecker cmd import) which can be used to export comments and review status for a particular run in a JSON based format from a running CodeChecker server and import it to another server.

# Export data from one server.
CodeChecker cmd export -n myrun \
  --url https://first-server.codechecker.com:443 2>/dev/null | python -m json.tool > myrun_export.json

# Import data to another server.
CodeChecker cmd import -i myrun_export.json  --url https://second-server.codechecker.com:443

Sparse and Cpplint analyzers support (#3160, #3248).

The report-converter tool was extend with two more analyzers:

• Sparse which is a semantic checker for C programs; it can be used to find a number of potential problems with kernel code.

v6.15.2

❗ ❗ ❗ Non-backward compatible changes ❗ ❗ ❗

• When a checker name and the alias of this checker is turned on, Clang Tidy (>=v11) will generate only one report where the checker names are concatenated with , mark (e.g.: cppcoreguidelines-avoid-magic-numbers,readability-magic-numbers). Unfortunately in previous CodeChecker releases we didn't handle this use case properly and we generated only one report from it. We changed this behaviour in #3238 so multiple reports will be generated for each checker name / alias if both are enabled.

• From this release, the CodeChecker analyze command will indicate only the success and failure of analysis by zero and non-zero exit codes respectively. Before, the analysis subcommand returned with 2, if there was any report in the analysis. Form this release, it will return with 0, if the analysis was successful irrespectively of the number of reports.
  The CodeChecker parse and CodeChecker cmd diff subcommand will return with value 2 if there is at least one (not suppressed) report in the result set (#3232, #3255).

  The return values of the subcommands is as follows:

  • CodeChecker analyze:
    0 - Successful analysis
    1 - CodeChecker error
    3 - Analysis of at least one translation unit failed
    128+signum - Terminating on a fatal signal whose number is signum

  • CodeChecker parse
    0 - No report
    1 - CodeChecker error
    2 - At least one report emitted by an analyzer

  • CodeChecker check
    0 - No report
    1 - CodeChecker error
    2 - At least one report emitted by an analyzer
    3 - Analysis of at least one translation unit failed
    128+signum - Terminating on a fatal signal whose number is signum

  • CodeChecker cmd diff
    0 - No difference between baseline and newrun
    1 - CodeChecker error
    2 - There is at least one report difference between baseline and newrun

• We moved from Travis CI to Github Actions (#3066, #3086, #3131).
• Unfortunately one of our core team member @gyorb left the project due to getting busy with other tasks. We wish you all the best and thank you very much for your hard work in the CodeChecker project 😊. Nevertheless, we hope that one day you return contributing! 😏

v6.15.0

New features

Web UI

• There is a brand new product statistics overview page with the information about the recently introduced or resolved reports or about the distribution of the reports in the product. #2986
• The run history list was moved from a separate tab to an expandable list under each run at the run list. This makes easier to find the relevant
  run history entries for each run. #2953
• New report info button to show more information about a report at the report details page (run name, detection/fix date ...) #2961
• Source components can be used to create and save file path filters with a name to show results only from those parts of the analyzed project. With the newly introduced other component every report which does not belong to any other component can be filtered. #2989

Command line interface (CLI)

• New exit status numbers for the CodeChecker analyze and check commands for better CI integration #2943:
  • 0 - Successful analysis and no new reports
  • 1 - CodeChecker error
  • 2 - At least one report emitted by an analyzer and there is no analyzer failure
  • 3 - Analysis of at least one translation unit failed
• Gerrit output format is available for the parse subcommand. This output format was only available for the CodeChecker cmd diff command in the previous releases. With this change the parse command can be used for the gerrit integration too #2745
  CodeChecker parse analyzer_reports -e gerrit

Report storage support for new source code analyzers

• Report conversion and storage support is available for multiple new source code analyzer tools (Coccinelle #2949, Smatch #2968, Kernel-Doc #2981). The report-converter tool can be used to convert the output of these analyzers to a format which can be stored to the web server or processed by other CodeChecker commands (parse, cmd diff ...).
  For more information about the tool configuration and usage check out the user documentation:
  • Coccinelle user documentation
  • Smatch user documentation
  • Kernel-Doc user documentation

Changes

• Open reports date filter was renamed to "Outstanding reports on a given date" on the web UI. #2990
  Also a new --outstanding-reports-date CLI filter argument was introduced as a filter option.
• Less code styling related checker groups are enabled by --enable-all flag.
  The --enable-all flag enabled a lot of style checkers which could generate a lot of styling reports. #3013

Further improvements worth mentioning

• Allow users to overwrite location of the session file #2976
• Show how many filter items are visible at the filter tool tip if there are more items #2862
• Show selected filter items at Review status filter #2940
• Improve component statistics page load performance #3018
• Enable search and highlight occurrences of the selected text at the source code view #3011
• Set analyzer name for clang-diagnostic checkers when the reports are stored #2956
• Reintroduce skipfile script for gerrit integration to be able to analyze only the changed files. #3008
• New severity levels for cppcoreguidelines-prefer-member-initializer, altera-struct-pack-align and bugprone-redundant-branch-condition checkers #2954, #2948

v6.14.0

New features

New statistics page in the Web UI

The statistics page got a new design with a lot of new features:

• statistics shown in separate tabs instead of one page for better visibility
• new, component statistics page, where reports are distributed per statistics, components can represent a part of a repository (directory, files)
• statistics comparison mode: you will be able compare the report statistics of two different analysis runs or time snapshot
• diff and review status filters are available on the statistics page
  #2897

Redesigned date selectors for the web UI filter and CLI

You will be able to list the open reports of your project for any date.
Open reports at a date are which were detected BEFORE the given date and NOT FIXED BEFORE the given date.
From the CLI the open reports can be queried like this:

CodeChecker cmd results --open-reports-date 2020:09:11:12:20 --url ...

Remember filters when navigate between pages

Filters are remembered during navigating between the pages. The report list and statistics related filters are saved separately.
#2913

Show analyzer name alongside the reports

Analysis results from multiple static analyzers can be stored to the database, with this change for each report the analyzer
name can be viewed which produced the result.
#2717

Always show similar reports

Reports with the same hash can be seen in a drop down list for each report without uniqueing #2896

Enable and disable checker profiles and guidelines (like sei-cert) in the analyzer CLI.

There is a new syntax extended with guideline support which can be used to enable checker sets.
With the new syntax the checkers, profiles and guideline can be enabled or disabled even if there is a conflict in their name.
The arguments may start with profile: of guideline: prefix which makes the choice explicit.
Without prefix it means a profile name, a guideline name or a checker group/name in this priority order.

CodeChecker analyze -o reports -e profile:sensitive -e guideline:sei-cert compile_command.json

Use these commands to list the available profiles
CodeChecker checkers --profile list
or guidelines:
CodeChecker checkers --guideline

New report converter for Markdownlint results

The reports from Markdownlint can be converted and stored
to the report serve like this:

# Run Markdownlint.
mdl /path/to/your/project > ./mdl_reports.out
# Use 'report-converter' to create a CodeChecker report directory from the
# analyzer result of Markdownlint.
report-converter -t mdl -o ./codechecker_mdl_reports ./mdl_reports.out
# Store Markdownlint reports with CodeChecker.
CodeChecker store ./codechecker_mdl_reports -n mdl

#2829

The codechecker config file was extended with a parse section which can be used by the parse subcommand.

It can be used to set the path prefixes in the CodeChecker config file which should be trimmed by the parse subcommand when the reports are printed:

{
  "parse": [
    "--trim-path-prefix",
    "/$HOME/workspace"
  ]
}

The config file for the parse command can be set like this:
CodeChecker parse report --config codechecker_cfg.json
#2885

Environment variables can be used in the CodeChecker config file, they will be expanded automatically

{
  "analyzer": [
    "--skip=$HOME/project/skip.txt"
  ]
}

#2877

Changes

On-demand Cross Translation Unit Analysis will be the default CTU analysis mode

The On-demand CTU analysis support introduced in the previous release is enabled by default now if the used
clang static analyzer supports it. CTU analysis will be performed without the huge temporary disc space allocation.

With the --ctu-ast-mode the analysis mode can be switched back to the old behavior if the new consumes too much memory:

CodeChecker analyze --ctu-ast-mode lod-from-pch ....

Further improvements worth mentioning

• Collect compiler information in case of clang mismatch #2872
• Log enabled checkers at the beginning of analysis #2858
• Add severity to statistics html page #2899
• Improve source component filter performance #2857
• Options specified on the command line after the --config option will override options specified in the config file #2883
• Compile command logging for make versions newer than 4.3 is fixed #2689
