Unreleased

[0.18.0] - 2024-02-13

📃 Details

Added

• ProgressBar trait and progress bar for package writing by @wolfv (#525)

Changed

• improved logging in package validation to include package path by @orhun (#521)
• use resolvo 0.4.0 with better error messages by @baszalmstra (#523)

Fixed

• allow multiple clobbers per package by @wolfv (#526)

[0.17.0] - 2024-02-01

✨ Highlights

This release contains some big changes to rattler:

Consistent clobbering

Rattler installs packages in parallel but this was at the cost of not being able to resolve files properly that existed in multiple packages. With this release we fixed this issue by creating a consistent clobbering experience. When a file is clobbered (installed by multiple packages) the last package in the topological ordering wins. This information is also recorded in the prefix itself which means that even if packages are added or removed from the environment the order remains consistent.

reqwest-middleware-client

The AuthenticatedClient has been rewritten by @vlad-ivanov-name. Instead of having a custom client for network requests we now use the reqwest-middleware crate. The rattler implementation adds a middleware that handles authentication. This changes makes it easier to integrate with other crates that use reqwest for network requests, and it allows users to add their own middleware.

Lock-file v4

The lock-file format has been updated to version 4. Originally our implementation was semi-compatible with conda-lock. We wanted to stay as close as possible to this format because it was already an established standard. However, with version 2 and 3 of the format we started to diverge more and more. We felt like the goals between both formats also started to diverge more and more so with version 4 we decided to completely abandon the conda-lock format and create our own. For more information about the lock-file format and the differences between conda-lock you can read the documentation. Note that all old formats (including the original conda-lock format) can still be parsed by rattler.

[0.6.0] - 2023-07-07

Highlights

New rust based solver implementation

This version of rattler includes a new solver implementation! @aochagavia worked hard on porting libsolv to rust and integrating that with rattler_solve. The port performs slightly faster or similar to the original C code and does not contain unsafe code, is well documented, and thread-safe. Our implementation (rattler_libsolv_rs) is specific to solving conda packages by leveraging rattler_conda_types for matching and parsing.

Some performance benchmarks taken on Apple M2 Max.

	libsolv-c	libsolv-rs
python=3.9	7.3734 ms	4.5831 ms
xtensor, xsimd	5.7521 ms	2.7643 ms
tensorflow	654.38 ms	371.59 ms
quetz	1.2577 s	1.3807 s
tensorboard=2.1.1, grpc-cpp=1.39.1	474.76 ms	132.79 ms

Run cargo bench libsolv to check the results on your own machine.

Besides the much improved implementation the new solver also provides much better error messages based on the work from mamba. When a conflict is detected the incompatibilities are analyzed and displayed with a more user-friendly error message.

The following packages are incompatible
|-- asdf can be installed with any of the following options:
    |-- asdf 1.2.3 would require
        |-- C >1, which can be installed with any of the following options:
            |-- C 2.0.0
|-- C 1.0.0 is locked, but another version is required as reported above

rattler-solve has also been refactored to accommodate this change. It is now more easily possible to switch between solvers add runtime by writing functions that are generic on the solver. The solvers now live in a separate module rattler_solve::libsolv_c for the original libsolv C implementation and rattler_solve::libsolv_rs for the rust version. Both solvers can be enabled with feature flags. The default features only select libsolv_c.

Caching of activation scripts

This release contains code to execute an activation script and capture the changes it made to the environment. Caching the result of an activation script can be useful if you need to invoke multiple executables from the same environment.

Details

Added

• Run activation scripts and capture their output by @baszalmstra in (#239)
• Support for sha256 and md5 field in matchspec by @0xbe7a in (#241)
• A rust port of libsolv as an additional solver backend by @aochagavia, @baszalmstra in (#243 & #253)
• Test cases and benchmarks for solver implementations by @baszalmstra in (#250 & #250)
• The ability to add a dependency from python on pip while loading repodata @wolfv in (#238)

Changed

• Completely refactored version parsing by @baszalmstra in (#240)
• Refactored solver interface to allow generic use of solver implementations by @baszalmstra in (#245)
• Also check if credentials stored under wildcard host by @wolfv in (#252)

Fixed

• Compilation issues by @wolfv in (#244)
• Add missing From<VersionWithSource> for Version by @baszalmstra in (#246)
• Optimized libsolv port by removing redundant MatchSpec parsing by @baszalmstra in (#246)
• Optimized libsolv port by caching matching Solvables by @baszalmstra in (#251)

[0.5.0] - 2023-06-30

Highlights

A bug fix release

Details

Added

• More control over how the PATH is altered during activation (#232)

Fixed

• Reconstructing of RepoData from conda lock files for local channels (#231)
• Powershell on Linux (#234)
• Proper parsing of >2.10* as >=2.10 (#237)

[0.4.0] - 2023-06-23

Highlights

A new algorithm was introduced to sort PackageRecords in a topological order based on their dependencies. Sorting in this way provides a deterministic way of sorting packages in the order in which they should be installed to avoid clobbering. The original algorithm was extracted from rattler-server.

Experimental extensions to the conda lock file format have also been introduced to make it possible to completely reproduce the original RepoDataRecords from a lock file.

Fixes were made to the MatchSpec and Version implementation to catch some corner cases and detecting the current shell has become more robust.

Details

Added

• PackageRecord::sort_topologically to perform a topological sort of PackageRecords (#218)
• Experimental fields to be able to reconstruct RepoDataRecord from conda lock files. (#221)
• Methods to manipulate Versions (#229)

Changed

• Refactored shell detection code using $SHELL or parent process name (#219)
• The error message that is thrown when parsing a Platform now includes possible options (#222)
• Completely refactored Version implementation to reduce memory footprint and increase readability (#227)

Fixed

• Issue with parsing matchspecs that contain epochs (#220)
• Zsh activation scripts invoke .sh scripts (#223)
• Detect the proper powershell parent process (#224)

[0.3.0] - 2023-06-15

Highlights

This release contains lots of fixes, small (breaking) changes, and new features. The biggest highlights are:

JLAP support

JLAP is a file format to incrementally update a cached repodata.json without downloading the entire file. This can save a huge amount of bandwidth for large repodatas that change often (like those from conda-forge). If you have a previously cached repodata.json on your system only small JSON patches are downloaded to bring your cache up to date. The format was initially proposed through a CEP and has been available in conda as an experimental feature since 23.3.0.

When using rattler you get JLAP support out of the box. No changes are needed.

Support for local file://

file:// based urls are now supported for all functions that use a Url to download certain data.

rattler_networking

A new crate has been added to facilitate authentication when downloading repodata or packages called rattler_networking.
