pipdeptree 4.2.13

on Python PyPI

Bug fixes

• On Windows, freeze output now writes an editable location as -e file:///C:/proj instead of -e C:\proj, which pip read as C:proj and rejected. This covers an editable install with no version control, one with no remote or an invalid remote, and one whose lookup timed out. On other platforms, a location that holds a backslash also becomes a file:// URL (#862) by @gaborbernat.
• Read direct_url.json, RECORD, .egg-link files, .hg/hgrc and .svn/entries only when they are regular files of at most 16 MiB, as METADATA already was. A FIFO in place of direct_url.json or RECORD made --freeze or --computed size wait for a writer, and a link to /dev/zero or a multi-gigabyte file made them allocate until the allocator or the OOM killer stopped the run. Freeze now prints the version pin for such a package, its size counts as zero, and an unreadable .egg-link, hgrc or entries file counts as absent (#855) by @gaborbernat.
• Stop waiting for a command at its timeout even when a process it started still holds its output open. A poetry wrapper script that ran the real command without exec used to keep the environment probe waiting until that command exited, past the 5 second timeout; the same applied to the VCS commands that freeze runs and to dot. Such a command now counts as timed out at the deadline, also when it exited first and left the other process running. pipdeptree does not stop that process (#849) by @gaborbernat.
• -o cyclonedx-json writes each --computed value as plain text, with one property per name for unique-deps-names. Before, a string kept its JSON quotes ("\"2.1 KB\"") and a list became one JSON array string. --depth help names the formats it applies to, and pipdeptree.render() no longer calls svg and ps binary formats when it rejects them by Bernát Gábor.
• -o json lists the metadata fields of each package in the order given to --metadata, as the other formats and pipdeptree 3.x do. Since 4.0.0 it sorted them by name by Bernát Gábor.
• from-index --requirements errors on Windows now name the requirements file as a plain C:\... path instead of the \\?\C:\... form. This covers file:line: invalid requirement, recursive requirements include and the nesting depth error by Bernát Gábor.
• from-index --requirements now prints a warning for each -i, --index-url or --extra-index-url line in a requirements file, naming the file, the line and the command-line flag to use instead. The resolve still ignores these lines, and --warn fail makes the run exit with code 1. Before, it skipped them without a word, so a pip-compile file for a private index resolved against PyPI with no hint why (#853) by @gaborbernat.
• from-index now rejects an -e / --editable line in a constraints file with source requirements cannot be constraints, the error a plain path or URL constraint already gets. Before, the editable project joined the resolve as an extra top-level requirement, so its dependencies could change the versions picked for the real requirements. pip refuses the same file (#850) by @gaborbernat.
• from-index now resolves a local project given as a bare file: URL, such as file:///abs/path or -e file:///abs/path, on the command line or in a requirements file. Before, it read the URL as a relative path and failed with No such file or directory (os error 2). A relative file: URL, bare or as name @ file:./pkg, now resolves against the working directory as pip does, where the named form used to read file:pkg as /pkg. A local source that cannot be read now fails with an error that names its path (#851) by @gaborbernat.
• from-index now treats an empty PIP_EXTRA_INDEX_URL as unset and reads the extra indexes from UV_EXTRA_INDEX_URL, as it already did for PIP_INDEX_URL and UV_INDEX_URL. Before, the empty value left the resolve with no extra index, so a package that only the UV_EXTRA_INDEX_URL index served failed to resolve by Bernát Gábor.
• meson setup works on systems that ship python3 without a python command. The stable ABI check now runs under the interpreter that runs Meson, the same one the build targets, instead of the first python on PATH (#856) by @gaborbernat.

Security

• Percent-encode whitespace and control characters in the URLs, VCS remotes and subdirectories of freeze output, and write an editable location that holds one as a file:// URL. Before, an installed distribution could add a line such as --index-url to the requirements file through its direct_url.json, .egg-link or a shipped checkout, and an escape sequence reached the terminal. An editable location with a space now installs with pip install -r instead of pip reading only the text before the space (#844) by @gaborbernat.
• Print the warnings the from-index resolver logs, such as a skipped release whose metadata does not parse, as a pipdeptree warning that --warn silence hides, with control characters replaced by U+FFFD. The same replacement now applies to Python errors the resolver raises. Before, Python wrote these warnings to stderr with the index's escape sequences intact, even under --warn silence (#847) by @gaborbernat.
• Reject a Requires-Dist marker, or a lock package marker, longer than 1024 bytes or with more than 16 extra comparisons before parsing it. Parsing builds a decision diagram that can double in size with each clause of extra alternatives, and a marker of about 900 bytes took 12 seconds and 15 GB of memory to parse. Installed metadata reports such a marker with the Invalid requirement found warning; from-lock stops with an error naming the package. pipdeptree also collects the extras a marker names by visiting each node of the parsed marker once, instead of converting it to disjunctive normal form, and from-lock stops with an error when the name of a dependencies entry is not a project name (#860) by @gaborbernat.
• Skip the interpreter that poetry env info --executable reports when it lies inside the project in the working directory, such as a .venv next to the pyproject.toml. With no virtual or conda environment active, a plain pipdeptree and --python auto used to run that interpreter, so a cloned repository that committed both ran its own program as the user. A plain run now inspects the interpreter running pipdeptree, and --python auto fails to detect an environment. To inspect that environment, activate it or pass its interpreter to --python by Bernát Gábor.
• Stop from-index with an error when the resolver pins a package name or version longer than 255 bytes, as from-lock already does. The text, JSON and freeze outputs copy a version once per edge, so an index could make them print megabytes from one long version (#843) by @gaborbernat.
