From chris at reproducible-builds.org Fri Jan 8 16:45:57 2021 From: chris at reproducible-builds.org (Chris Lamb) Date: Fri, 8 Jan 2021 11:45:57 -0500 (EST) Subject: [diffoscope] =?utf-8?q?diffoscope_164_released_=F0=9F=92=A0?= Message-ID: <161012439930.1688095.16574570539947110533@tinycat.chris-lamb.co.uk> Hi, The diffoscope maintainers are pleased to announce the release of version 164 of diffoscope. diffoscope tries to get to the bottom of what makes files or directories different. It will recursively unpack archives of many kinds and transform various binary formats into more human-readable form to compare them. It can compare two tarballs, ISO images, or PDF just as easily. Version 164 includes the following changes: [ Chris Lamb ] * Truncate jsondiff differences at 512 bytes lest they consume the entire page. * Wrap our external call to cmp(1) with a profile (to match the internal profiling). * Add a note regarding the specific ordering of the new all_tools_are_listed test. [ Dimitrios Apostolou ] * Performance improvements: - Improve speed of has_same_content by spawning cmp(1) less frequently. - Log whenever the external cmp(1) command is spawn.ed - Avoid invoking external diff for identical, short outputs. * Rework handling of temporary files: - Clean up temporary directories as we go along, instead of at the end. - Delete FIFO files when the FIFO feeder's context manager exits. [ Mattia Rizzolo ] * Fix a number of potential crashes in --list-debian-substvars, including explicitly listing lipo and otool as external tools. - Remove redundant code and let object destructors clean up after themselves. [ Conrad Ratschan ] * Add a comparator for Flattened Image Trees (FIT) files, a boot image format used by U-Boot. ## Download Version 164 is available from Debian unstable as well as PyPI, and will shortly be available on other platforms surely.

It will recursively unpack archives of many kinds and transform various binary formats into more human-readable form to compare them. It can compare two tarballs, ISO images, or PDF just as easily. Version 165 includes the following changes: [ Dimitrios Apostolou ] * Introduce the --no-acl and --no-xattr arguments [later collapsed to --extended-filesystem-attributes] to improve performance. * Avoid calling the external stat command. [ Chris Lamb ] * Collapse --acl and --xattr into --extended-filesystem-attributes to cover all of these extended attributes, defaulting the new option to false (ie. to not check these very expensive external calls). [ Mattia Rizzolo ] * Override several lintian warnings regarding prebuilt binaries in the * source. * Add a pytest.ini file to explicitly use Junit's xunit2 format. * Ignore the Python DeprecationWarning message regarding the `imp` module deprecation as it comes from a third-party library. * debian/rules: filter the content of the d/*.substvars files ## Download Version 165 is available from Debian unstable as well as PyPI, and will shortly be available on other platforms surely.

It will recursively unpack archives of many kinds and transform various binary formats into more human-readable form to compare them. It can compare two tarballs, ISO images, or PDF just as easily. Version 166 includes the following changes: [ Chris Lamb ] * New features and bugfixes: - Explicitly remove our top-level temporary directory. (Closes: #981123, reproducible-builds/diffoscope#234) - Increase fuzzy matching threshold to 130 ensure that we show more differences. (Closes: reproducible-builds/diffoscope#232) - Save our sys.argv in our top-level temporary directory in case it helps debug current/errant temporary directories. - Prefer to use "magic.Magic" over the "magic.open" compatibility interface. (Closes: reproducible-builds/diffoscope#236) - Reduce fuzzy threshold to 110 to prevent some test failures. (Closes: reproducible-builds/diffoscope#233) * Output improvements: - Show fuzzyness amount in percentage terms, not out of the rather-arbitrary "400". - Improve the logging of fuzzy matching. - Print the free space in our temporary directory when we create it, not from within diffoscope.main. * Codebase improvements: - Tidy the diffoscopecomparators.utils.fuzzy module. - Update my copyright years. - Clarify the grammar of a comment. - Clarify in a comment that __del__ is not always called, so temporary directories are not neccessary removed the *moment* they go out of scope. [ Conrad Ratschan ] * Fix U-Boot Flattened Image Tree ("FIT") image detection for larger image files.
