v32.1.0 (next, roadmap)

New CLI options:

• A new CLI option --package-only has been added which performs a faster package scan by skipping the package assembly step and also skipping license/copyright detection on package metadata.

Major API/other changes:

• Output Format Version updated to 3.1.0 (minor version bump)
• Drops python 3.7 and adopts python 3.12
• New license match attributes: - from_file - matched_text_diagnostics is added for --license-text-diagnostics
• In codebase-level license_detections we have a new attribute reference_matches
• SPDX license expressions everywhere side-by-side with ScanCode license expressions.
• All rule attribute level data provided in codebase level todo items.

Changes in Output Data Structure:

• The data structure of the JSON output has changed for licenses at file level, and license detections at top-level. But note that all the changes are additions to the JSON output, so we have a minor version bump 3.0.0 to 3.1.0:

  • There is a new attribute from_file in matches which is in license_detections in: * File level license_detections * Codebase level license_detections * license_detections and other_license_detections in

    file-level package_data

    • license_detections and other_license_detections in codebase level packages

  • On using the CLI option --license-text-diagnostics there is now a new license match attribute matched_text_diagnostics with the matched text and highlighted diagnostics, instead of having this replace the plain matched_text.

  • A new reference_matches attribute is added to codebase-level license_detections which is same as the matches attribute in other license detections.

  • We now have SPDX license expressions everywhere we have ScanCode license expressions for ease of use and adopting SPDX everywhere. A new attribute license_expression_spdx is added to: - license_detections in file and codebase level - in package license_detections and other_license_detections - matches for license_detections everywhere

  • Adds all rule atrribute level info in codebase level todo data, to assist in review. This includes length, text, notes, referenced_filenames, and the boolean attributes (like is_license_notice, is_license_intro etc, as applicable).

• New and updated licenses, including support for newly released SPDX license list versions: - SPDX License List 3.22:

  This release of the SPDX license list had 48 new licenses, and several of them we already had as licenses/rules, and these has been modified to be consistent with the SPDX list. And the rest have been added as new licenses. For more details see #3554

  • SPDX License List 3.23: This release of the SPDX license list had 43 new licenses, and out of them 22 were present as licenses and 10 were present as rules already. There were 4 new license/exception texts added, and the rest were either texts with small variations, additions to texts or several rule texts together. For more details see #3653
  • We also have lots of other misc new licenses and rules added to LicenseDB, see PRs below for more details: #3663 #3642 #3586 #3584 #3575 #3570 #3568 #3562

• Improve debian namespace detection based on clues and fix namespace and qualifier bugs for debian purls. For more details see nexB/scancode.io#899 and #3443 Also improve debian manifests parsing and purl parsing from filenames. Support for nexB/purldb#245 Bumps debian-inspector to v31.1.0

• Bump commoncode to v31.0.3

• Upgraded spdx-tools dependency to v0.8. See #3455

Support for Conan package parser:

• We now support the parsing of Conan manifest files, such as conanfile.py, as described here https://docs.conan.io/2.0/reference/conanfile.html. We also support source extraction from conandata.yml, as described here https://docs.conan.io/2/tutorial/creating_packages/handle_sources_in_packages.html#using-the-conandata-yml-file.

v32.0.5rc2 - 2023-06-22

The previous release v32.0.5rc1 failed to upload pypi wheels because of file size limits enforced by pypi, and this release is effectively the same as the previous one, but now the size limit has been increased by pypi/support#2926 so this will upload the wheels correctly.

v32.0.5rc1 - 2023-06-12

here in typecode we had an improper import of ctypes.utils and this is fixed in a new release v30.0.1 of typecode

• #3408 the setup.cfg and setup-mini.cfg was not aligned for plugin entrypoints.

v32.0.0 - 2023-05-23

Important API changes:

This is a major release with major API and output format changes and signicant feature updates.

In particular the output format has changed for the licenses and packages, and also for some of the command line options.

The output format version is now 3.0.0.

Other updates

• We have a new --todo CLI option to have todo items for reviewers with ambiguous license detections and package detections. This adds a new codebase-level attribute todo which is a list of ambiguous detections. Here the ambiguous detection attributes are: - detection_id: same license unique license detection identifier or top-level

  package identifier.

  • detection: this is either a license_detection or a package_data mapping.
  • review_comments: to explain the type of ambiguous detections.

Package detection:

• Update GemfileLockParser to track the gem which the Gemfile.lock is for, which we assign to the new GemfileLockParser.primary_gem field. Update GemfileLockHandler.parse() to handle the case where there is a primary gem detected from a gemfile.lock. If there is a primary gem, a single Package is created and the detected gem data within the gemfile.lock are assigned as dependencies. If there is no primary gem, then all of the dependencies are collected into Package with no name and yielded.

  #3072

• Fix issue where dependencies were not reported when scanning an extracted Python project by modifying BaseExtractedPythonLayout.assemble() to favor using package data from a PKG-INFO file from an egg-info directory. Package data from a PKG-INFO file from an egg-info directory contains the dependency information collected from the requirements.txt file along side PKG-INFO.

  #3083

• Fix issue where we were returning incorrect purl package type for cocoapods. pods was being returned as a purl type for cocoapods, it should be cocoapods instead. https://github.com/package-url/purl-spec/blob/master/PURL-TYPES.rst#cocoapods

  #3081

• Code for parsing a Maven POM, npm package.json, freebsd manifest and haxelib JSON have been separated into two functions: one that creates a PackageData object from the parsed Resource, and another that calls the previous function and yields the PackageData. This was done such that we can use the package manifest data parsing code outside of the scancode-toolkit context in other libraries.

• The PackageData model now includes a holder field, which is populated with holder data extracted from the copyright field if copyright data is present, otherwise it remains empty.

  #3290

• DatafileHandlers now have a classmethod named get_top_level_resources(), which is supposed to yield the top-level Resources of a Package codebase, relative to a Package manifest file. maven.MavenPomXmlHandler is the first DatafileHandler that has this method implemented.

License detection:

• The SPDX license list has been updated to the latest v3.20

• This is a major update to license detection where we now combine one or more license matches in a larger license detection. This approach improves the accuracy of license detection and removes a larger number of false positive or ambiguous license detections. See for details #2878

• There is a new license_detections codebase level attribute with all the unique license detections in the whole scan, both in resources and packages. This has the 3 attributes also present in package/resource level license detections: license_expression, identifier and detection_log (present optionally if the --license-diagnostics option is enabled) with an additional attribute:

  • count: Number of times in the codebase this unique license detection was encountered.

• The data structure of the JSON output has changed for licenses at file level:

  • The licenses attribute is deleted.
  • A new license_detections attribute contains license detections in that file. This object has three attributes: license_expression, identifier and matches. matches is a list of license matches and is roughly the same as licenses in the previous version with additional structure changes detailed below. Identifier is the detected license-expression with an UUID generated from the content of matches such that this is unique for unique detections. We also have another attribute detection_log with diagnostics information if the --license-diagnostics option is enabled.
  • A new attribute license_clues contains license matches with the same data structure as the matches attribute in license_detections. This contains license matches that are mere clues and where not considered to be a proper conclusive license detection.
  • The license_expressions list of license expressions is deleted and replaced by a detected_license_expression single expression. Similarly spdx_license_expressions was removed and replaced by detected_license_expression_spdx.
  • See license updates documentation for examples and details.

• The data structure of license attributes in package_data and the codebase level packages has been updated accordingly:

  • There is a new license_detections attribute for the primary, top-level declared licenses of a package and an other_license_detections attribute for the other secondary detections.

  • The license_expression is replaced by the declared_license_expression and other_license_expression attributes with their SPDX counterparts declared_license_expression_spdx and other_license_expression_spdx. These expressions are parallel to detections.

  • The declared_license attribute is renamed extracted_license_statement and is now a YAML-encoded string, which can be parsed to recreate the original extracted license statement. Previously this used to be nested python objects lists/dicts/string, but now this is always a YAML string.

    See license updates documentation for examples and details.

• The license matches structure has changed: we used to report one match for each license key of a matched license expression. We now report instead one single match for each matched license expression, and list the license keys as a licenses attribute. This avoids data duplication. Inside each match, we list each match and matched rule attributred directly avoiding nesting. See license updates doc for examples and details.

• There are new and codebase level attributes with --license-references to report reference license metadata and texts once for each license matched across the scan; we now have two codebase level attributes: license_references and license_rule_references that list unique detected license and license rules. for examples and details. This reference data is also removed from license matches in all levels i.e. from codebase, package and resource level license detections and resource level license clues, irrespective of this CLI option being used, i.e. default with --licenses. See license updates documentation

• We replaced the scancode --reindex-licenses command line option with a new separate command named scancode-reindex-licenses.

  • The --reindex-licenses-for-all-languages CLI option is also moved to the scancode-reindex-licenses command as an option --all-languages.
  • We can now detect licenses using custom license texts and license rules stored in a directory or packaged as a plugin for consistent reuse and deployment.
  • There is an --additional-directory option with the scancode-reindex-licenses command to add the licenses from a directory.
  • There is also a --only-builtin option to use ony builtin licenses ignoring any additional license plugins.
  • See #480 for more details.

• We combined the license data file and text file of each license in a single file with a .LICENSE extension. The .yml data file is now included at the top of each .LICENSE file as "YAML frontmatter". The same applies to license rules and their .RULE and .yml files. This halves the number of data files from about 60,000 to 30,000. Git line history is preserved for the combined

  text + yml files.

  • See #3049

• There is a new console script scancode-license-data to export license data in JSON, YAML and HTML, with indexes and a static website for use in the licensedb web site. This becomes the API way to getr scancode license data.

  See #2738

• The deprecated "--is-license-text" option has been removed. This is now built-in with the --license-text option and --info and exposed with the "percentage_of_license_text" attribute.

• The license dump() has been modified to add an extra space at empty newlines for license files which also have multiple indentation levels as this was generating invalid YAML output files when --license-text or --license-references was enabled.

  See #3219

• A bugfix has been added to the --unknown-licenses option where we would crash when using this option without using --matched-text option. This is now working correctly and also better tested.

  See #3343

v31.0.0 - 2022-08-17

This is a major release with important bug and security fixes, new and improved features and API changes.

Note that we no longer support Python 3.6. Use Python 3.7+ instead.

Important API changes:

• The data structure of the JSON output has changed for copyrights, authors and holders. We now use a proper name for attributes and not a generic "value".
• The data structure of the JSON output has changed for packages. We now return "package_data" package information at the manifest file-level rather than "packages". This has all the data attributes of a "package_data" field plus others: "package_uuid", "package_data_files" and "files".
  • There is a a new top-level "packages" attribute that contains package instances that can be aggregating data from multiple manifests.
  • There is a a new top-level "dependencies" attribute that contains each dependency instance, these can be standalone or releated to a package. These contain a new "extra_data" object.
  • There is a new resource-level attribute "for_packages" which refers to packages through package_uuids (pURL + uuid string).
• The data structure for HTML output has been changed to include emails and urls under the "infos" object. The HTML template displays output for holders, authors, emails, and urls into separate tables like "licenses" and "copyrights".
• The data structure for CSV output has been changed to rename the Resource column to "path". "copyright_holder" has been renamed to "holder"
• The license clarity scoring plugin has been overhauled to show new license clarity criteria. More details of the new scoring criteria are provided below.
• The functionality of the summary plugin has been imprived to provide declared origin and license information for the codebase being scanned. The previous summary plugin functionality has been preserved in the new tallies plugin. More details are provided below.
• ScanCode has adopted the new code skeleton from https://github.com/nexB/skeleton The key change is the location of the virtual environment. It used to be created at the root of the scancode-toolkit directory. It is now created under the venv subdirectory. You mus be aware of this if you use ScanCode from a git clone
• DatafileHandler.assemble(), DatafileHandler.assemble_from_many(), and the other .assemble() methods from the other Package handlers from packagedcode, have been updated to yield Package items before Dependency or Resource items. This is particulary important in the case where we are calling the assemble() method outside of the scancode-toolkit context, where we need to ensure that a Package exists before we assocate a Resource or Dependency to it.

Copyright detection:

• The data structure in the JSON is now using consistently named attributes as opposed to plain values.
• Several copyright detection bugs have been fixed.
• French and German copyright detection is improved.
• Some spurious trailing dots in holders are not stripped.

License detection:

• There have been significant license detection rules and licenses updates:
  • 107 new licenses have been added (total is now 1954)
  • 6780 new license detection rules have been added (total is now 32259)
  • 6753 existing false positive license rules have been removed (see below).
  • The SPDX license list has been updated to the latest v3.17
• The rule attribute "only_known_words" has been renamed to "is_continuous" and its meaning has been updated and expanded. A rule tagged as "is_continuous" can only be matched if there are no gaps between matched words, be they stopwords, extra unknown or known words. This improves several false positive license detections. The processing for "is_continous" has been merged in "key phrases" processing below.
• Key phrases can now be defined in a RULE text by surrounding one or more words with double curly braces {{ and }}. When defined a RULE will only match when the key phrases match exactly. When all the text of rule is a "key phrase", this is the same as being "is_continuous".
• The "--unknown-licenses" option now also detects unknown licenses using a simple and effective ngrams-based matching in area that are not matched or weakly matched. This helps detects things that look like a license but are not yet known as licenses.
• False positive detection of "license lists" like the lists seen in license and package management tools has been entirely reworked. Rather than using thousands of small false positive rules, there is a new filter to detect a long run of license references and tags that is typical of license lists. As a results, thousands of rules have been replaced by a simpler filter, and the license detection is more accurate, faster and has fewer false positives.
• The new license flag "is_generic" tags licenses that are "generic" licenses such as "other-permissive" or "other-copyleft". This is not yet returned in the JSON API.
• When scanning binary files, the detection of single word rules is filtered when surrounded by gibberish or mixed case. For instance $#%$GpL$ is a false positive and is no longer reported.
• Several rules we tagged as is_license_notice incorrectly but were references and have been requalified as is_license_reference. All rules made of a single ord have been requalified as is_license_reference if they were not qualified this way.
• Matches to small license rules (with small defined as under 15 words) that are scattered over too many lines are now filtered as false matches.
• Small, two-words matches that overlap the previous or next match by by the word "license" and assimilated are now filtered as false matches.
• The new --licenses-reference option adds a new "licenses_reference" top level attribute to a scan when using the JSON and YAML outputs. This contains all the details and the full text of every license seen in a file or package license expression of a scan. This can be added added after the fact using the --from-json option.
• New experimental support for non-English licenses. Use the command ./scancode --reindex-licenses-for-all-languages to index all known non-English licenses and rules. From that point on, they will be detected. Because of this some licenses that were not tagged with their languages are now correctly tagged and they may not be detected unless you activate this new indexing feature.

Package detection:

• Major changes in package detection and reporting, codebase-level attribute packages with one or more package_data and files for the packages are reported. The specific changes made are:
  • The resource level attribute packages has been renamed to package_data, as these are really package data that are being detected, such as manifests, lockfiles or other package data. This has the data attributes of a package_data field plus others: package_uuid, package_data_files and files.
  • A new top-level attribute packages has been added which contains package instances created from package_data detected in the codebase.
  • A new codebase level attribute dependencies has been added which contains dependency instances created from lockfiles detected in the codebase.
  • The package attribute root_path has been deleted from package_data in favour of the new format where there is no root conceptually, just a list of files for each package.
  • There is a new resource-level attribute for_packages which refers to packages through package_uids (pURL + uuid string). A package_adder function is now used to associate a Package to a Resource that is part of it. This gives us the flexibility to use the packagedcode Package handlers in other contexts where for_packages on Resource is not implemented in the same way as scancode-toolkit.
  • The package_data attribute dependencies (which is a list of DependentPackages), now has a new attribute resolved_package with a package data mapping. Also the requirement attribute is renamed to extracted_requirement. There is a new extra_data to collect extra data as needed.
• For Pypi packages, python_requires is treated as a package dependency.

License Clarity Scoring Update:

• We are moving away from the original license clarity scoring designed for ClearlyDefined in the license clarity score plugin. The previous license clarity scoring logic produced a score that was misleading when it would return a low score due to the stringent scoring criteria. We are now using more general criteria to get a sense of what provenance information has been provided and whether or not there is a conflict in licensing between what licenses were declared at the top-level key files and what licenses have been detected in the files under the top-level.
• The license clarity score is a value from 0-100 calculated by combining the weighted values determined for each of the scoring elements:
  • Declared license:
    • When true, indicates that the software package licensing is documented at top-level or well-known locations in the software project, typically in a package manifest, NOTICE, LICENSE, COPYING or README file.
    • Scoring Weight = 40
  • Identification precision:
    • Indicates how well the license statement(s) of the software identify known licenses that can be designated by precise keys (identifiers) as provided in a publicly available license list, such as the ScanCode LicenseDB, the SPDX license list, the OSI license list, or a URL pointing to a specific license text in a project or organization website.
    • Scoring Weight = 40
  • License texts:
    • License texts are provided to support the declared license expression in files such as a package manifest, NOTICE, LICENSE, COPYING or README.
    • Scoring Weight = 10
  • Declared copyright:
    • When true, indicates that the software package copyright is documented at top-level or well-known locations in the software project, typically in a package manifest, NOTICE, LICENSE, COPYING or README file.
    • Scoring Weight = 10
  • Ambiguous compound licensing:
    • When true, indicates that the software has a license declaration that makes it difficult to construct a reliable license expression, such as in the case of multiple licenses where the conjunctive versus disjunctive relationship is not well defined.
    • Scoring Weight = -10
  • Conflicting license categories:
    • When true, indicates that the declared license expression of the software is in the permissive category, but that other potentially conflicting categories, such as copyleft and proprietary, have been detected in lower level code.
    • Scoring Weight = -20

Summary Plugin Update:

• The summary plugin's behavior has been changed. Previously, it provided a count of the detected license expressions, copyrights, holders, authors, and programming languages from a scan.

  We have preserved this functionality by creating a new plugin called tallies. All functionality of the previous summary plugin have been preserved in the tallies plugin.

• The new summary plugin now attempts to determine a declared license expression, declared holder, and the primary programming language from a scan. And the updated license clarity score provides context on the quality of the license information provided in the codebase key files.

• The new summary plugin also returns lists of tallies for the other "secondary" detected license expressions, copyright holders, and programming languages.

All summary information is provided at the codebase-level attribute named summary.

Outputs:

• Added new outputs for the CycloneDx format. The CLI now exposes options to produce CycloneDx BOMs in either JSON or XML format
• A new field warnings has been added to the headers of ScanCode toolkit output that contains any warning messages that occur during a scan.
• The CSV output format --csv option is now deprecated. It will be replaced by new CSV and tabular output formats in the next ScanCode release. Visit #3043 to provide inputs and feedback.

Output version

Scancode Data Output Version is now 2.0.0.

Changes:

• Rename resource level attribute packages to package_data.

• Add top-level attribute packages.

• Add top-level attribute dependencies.

• Add resource-level attribute for_packages.

• Remove package-data attribute root_path.

• The fields of the license clarity scoring plugin have been replaced with the following fields. An overview of the new fields can be found in the "License Clarity Scoring Update" section above.

  • score
  • declared_license
  • identification_precision
  • has_license_text
  • declared_copyrights
  • conflicting_license_categories
  • ambigious_compound_licensing

• The fields of the summary plugin have been replaced with the following fields. An overview of the new fields can be found in the "Summary Plugin Update" section above.

  • declared_license_expression
  • license_clarity_score
  • declared_holder
  • primary_language
  • other_license_expressions
  • other_holders
  • other_languages

• A new field run_order has been added to BasePlugin and set on all ScanCode plugins. Plugin run order and output order are now set independently of one another.

Documentation Update

• Various documentation files have been updated to reflects API changes and correct minor documentation issues.

Development environment and Code API changes:

• The main package API function get_package_infos is deprecated, and replaced by get_package_data.
• The Resources path are always the same regardless of the strip-root or full-root arguments.
• The license cache consistency is not checked anymore when you are using a git checkout. The SCANCODE_DEV_MODE tag file has been removed entirely. Use instead the --reindex-licenses option to rebuild the license index.
• We can now regenerate test fixtures using the new SCANCODE_REGEN_TEST_FIXTURES environment variable. There is no need to replace the regen=False with regen=True in the code.

Miscellaneous

• Added support for usage of shortcut flags - -A or --about - -q or --quiet - -v or --verbose - -V or --version can be used.

v30.1.0 - 2021-09-25

This is a bug fix release for these bugs:

Thank you to: - Thomas Druez @tdruez

v30.0.1 - 2021-09-24

This is a minor bug fix release for these bugs:

• nexB/commoncode#31
• #2713

We now correctly work with all supported Click versions.

Thank you to: - Konstantin Kochin @vznncv - Thomas Druez @tdruez

v30.0.0 - 2021-09-23

This is a major release with new features, and several bug fixes and improvements including major updates to the license detection.

We have droped using calendar-based versions and are now switched back to semver versioning. To ensure that there is no ambiguity, the new major version has been updated from 21 to 30. The primary reason is that calver was not helping integrators to track major version changes like semver does.

We also have introduced a new JSON output format version based on semver to version the JSON output format data structure and have documented the new versioning approach.

Package detection:

• The Debian packages declared license detection in machine readable copyright files and unstructured copyright has been significantly improved with the tracking of the detection start and end line of a license match. This is not yet exposed outside of tests but has been essential to help improve detection.
• Debian copyright license detection has been significantly improved with new license detection rules.
• Support for Windows packages has been improved (and in particular the handling of Windows packages detection in the Windows registry).
• Support for Cocoapod packages has been significantly revamped and is now working as expected.
• Support for PyPI packages has been refined, in particular package descriptions.

Copyright detection:

• The copyright detection accuracy has been improved and several bugs have been fixed.

License detection:

There have been some significant updates in license detection. We now track 34,164 license and license notices:

• 84 new licenses have been added,
• 34 existing license metadata have been updated,
• 2765 new license detection rules have been added, and
• 2041 existing license rules have been updated.

• Several license detection bugs have fixed.
• The SPDX license list 3.14 is now supported and has been synced with the licensedb. We also include the version of the SPDX license list in the ScanCode YAML, JSON and the SPDX outputs, as well as display it with the "--version" command line option.
• Unknown licenses have a new flag "is_unknown" in their metadata to identify them explicitly. Before that we were just relying on the naming convention of having "unknown" as part of a license key.
• Rules that match at least one unknown license have a flag "has_unknown" set and returned in the match results.
• Experimental: License detection can now "follow" license mentions that reference another file such as "see license in COPYING" where we can relate this mention to the actual license detected in the COPYING file. Use the new "--unknown-licenses" command line option to test this new feature. This feature will evolve significantly in the next version(s).

Outputs:

• The SPDX output now has the mandatory ids attribute per SPDX spec. And we support SPDX 2.2 and SPDX license list 3.14.

Miscellaneous

• There is a new "--no-check-version" CLI option to scancode to bypass live, remote outdated version check on PyPI
• The scan results and the CLI now display an outdated version warning when the installed ScanCode version is older than 90 days. This is to warn users that they are relying on outdated, likely buggy, insecure and inaccurate scan results and encourage them to update to a newer version. This is made entirely locally based on date comparisons.
• We now display again the command line progressbar counters correctly.
• A bug has been fixed in summarization.
• Generated code detection has been improved with several new keywords.

Thank you!

• Licenses data now contains the full name as well as the short name.
• License match have a notion of "coverage" which is the number of matched words compared to the number of words in the matched rule.
• The license cache is not checked anymore for consistency once created which improved startup times. (unless you are using a Git checkout and you are developping with a SCANCODE_DEV_MODE tag file present)
• License catagory names have been improved

Copyrights:

• Copyright detection in binary files has been improved
• There are several improvements to the copyright detection quality fixing these tickets: #795 #677 #305 #795
• There is a new post scan plugin that can be used to ignore certain copyright in the results

• Make all copyright tests data driven using YAML files like for license tests

Plugins

• Prescan plugins can now exclude files from the scans
• Plugins can now contribute arbitrary command line options #787 and #748
• there is a new plugin stage called output_filter to optionally filter a scan before output. One example is to keep "only findings" #787
• The core processing is centered now on a Codebase and Resource abstraction that represents the scanned filesystem in memory #717 #736 All plugins operate on this abstraction
• All scanners are also plugins #698 and now everything is a plugin including the scans
• The interface for output plugins is the same as other plugins #715

v2.2.1 (2017-10-05)

This is a minor release with several bug fixes, one new feature and one (minor) API change.

API change:

• Licenses data now contains a new reference_url attribute instead of a dejacode_url attribute. This defaults to the public DejaCode URL and can be configured with the new --license-url-template command line option.

New feature:

• There is a new "--format jsonlines" output format option. In this format, each line in the output is a valid JSON document. The first line contains a "header" object with header-level data such as notice, version, etc. Each line after the first contains the scan results for a single file formatted with the same structure as a whole scan results JSON documents but without any header-level attributes. See also http://jsonlines.org/

Other changes:

• Several new and improved license detection rules have been added. The logic of detection has been refined to handle some rare corner cases. The underscore character "_" is treated as part of a license word and the handling of negative and false_positive license rules has been simplified.
• Several issues with dealing with codebase with non-ASCII, non-UTF-decodable file paths and other filesystem encodings-related bug have been fixed.
• Several copyright detection bugs have been fixed.
• PHP Composer and RPM packages are now detected with --package
• Several other package types are now detected with --package even though only a few attribute may be returned for now until full parser are added.
• Several parsing NPM packages bugs have been fixed.
• There are some minor performance improvements when scanning some large file for licenses.

v2.1.0 (2017-09-22)

This is a minor release with several new and improved features and bug fixes but no significant API changes.

• New plugin architecture by @yashdsaraf

• we can now have pre-scan, post-scan and output format plugins
• there is a new CSV output format and some example, experimental plugins
• the CLI UI has changed to better support these plugins

• New and improved licenses and license detection rules including support for EPL-2.0 and OpenJDK-related licensing and synchronization with the latest SPDX license list
• Multiple bug fixes such as:
  • Ensure that authors are reported even if there is no copyright #669
  • Fix Maven package POM parsing infinite loop #721
  • Improve handling of weird non-unicode byte paths #688 and #706
  • Improve PDF parsing to avoid some crash #723

v2.0.1 (2017-07-03)

This is a minor release with minor new and improved features and bug fixes.

• New and improved license detection, including refined match scoring for #534
• Bug fixed in License detection leading to a very long scan time for some rare JavaScript files. Reported by @jarnugirdhar
• New "base_name" attribute returned with file information. Reported by @chinyeungli
• Bug fixed in Maven POM package detection. Reported by @kalagp

v2.0.0 (2017-06-23)

This is a major release with several new and improved features and bug fixes.

Some of the key highlights include:

License detection:

• Brand new, faster and accurate detection engine using multiple techniques eventually doing multiple exhaustive comparisons of a scanned file content against all the license and rule texts.
• Several new licenses and over 2500+ new and improved licenses detection rules have been added making the detection significantly better (and weirdly enough faster too as a side-effect of the new detection engine)
• the matched license text can be optionally returned with the --license-text option
• The detection accuracy has been benchmarked against other detection engine and ScanCode has shown to be more accurate and comprehensive than all the other engines reviewed.
• improved scoring of license matches

Package and dependencies:

• new and improved detection of multiple package formats: NPM, Maven, NuGet, PHP Composer, Python Pypi and RPM. In most cases direct, declared dependencies are also reported.
• several additional package formats will be reported in the future version.
• note: the structure of Packages data is evolving and should not be considered API at this stage

Scan outputs:

• New SPDX tag/values and RDF outputs.
• new compact JSON format (the pretty printed format is still available with the the json-pp format). The JSON format has been changed significantly and is closer to a documented, standard format that we call the ABC data format.
• Minor refinements on the html and html-app format. Note that the html-app format will be deprecated and replaced by the new AboutCode Manager desktop app (electron-based) in future versions.

• Copyright: Improved copyright detection: several false positive are no longer returned and copyrights are more accurate
• Archive: support for shallow extraction and support for new archive types (such as Spring boot shell archives)

Performance:

• Everything is generally faster, and license detection performance has been significantly improved.
• Scans can run on multiple processes in parallel with the new --processes option speeding up things even further. A scan of a full Debian pool of source packages was reported to scan in about 11 hours (on a rather beefy 144 cores, 256GB machine)
• Reduced memory usage with the use of caching

Other notes:

• This is the last release with Linux 32 bits architecture support
• The scan of a file can be interrupted after a timeout with a 120 seconds default
• ScanCode is now available as a library on the Pypi Python package index for use as a library. The documentation for the library usage will follow in future versions
• New --ignore option: You can optionally ignore certain file and paths during a scan
• New --diag option: display additional debug and diagnostic data
• The scanned file paths can now reported as relative, rooted or absolute with new command line options with a default to a rooted path.

Thank you to all contributors to this release and the 200+ stars and 60+ forks on GitHub!
