From 0eda05963f3c70c3969ddd2aa72926b871ef4b07 Mon Sep 17 00:00:00 2001 From: Joseph Hunkeler Date: Tue, 20 Aug 2024 10:45:09 -0400 Subject: Pypi existence check (#30) * Add python_package_exists() function * Poll pypi.org or compatible index to see if a package exists * Returns non-zero on success * Implements python_package_exists() in delivery_defer_packages() * Implements python_package_exists() in delivery_defer_packages() * Bugfix: Avoid incorrect package selection * With large package lists that contain multiple packages starting with the same strstr() would pick the first match * This adds a temporary name variable that strcmp() can check against. * Message correction: * Change "release" to "testing" in testing environment failure message * Amend message to fit the flow of the output * Disable outdated conda notifications * The latest version isn't always the greatest. Don't give the end-user any ideas. Just use whatever the installer provides... quietly * Rename python_package_exists to pip_index_provides * Document the function prototype * Add missing comments in micromamba structure * Ensure the temporary output file does not linger --- include/conda.h | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) (limited to 'include') diff --git a/include/conda.h b/include/conda.h index d439371..c546672 100644 --- a/include/conda.h +++ b/include/conda.h @@ -7,10 +7,11 @@ #include "core.h" #define CONDA_INSTALL_PREFIX "conda" +#define PYPI_INDEX_DEFAULT "https://pypi.org/simple" struct MicromambaInfo { - char *micromamba_prefix; - char *conda_prefix; + char *micromamba_prefix; //!< Path to write micromamba binary + char *conda_prefix; //!< Path to install conda base tree }; /** @@ -181,4 +182,14 @@ int conda_env_export(char *name, char *output_dir, char *output_filename); * @return exit code from "conda" */ int conda_index(const char *path); + +/** + * Determine whether a simple index contains a package + * @param index_url a file system path or url pointing to a simple index + * @param name package name (required) + * @param version package version (may be NULL) + * @return not found = 0, found = 1, error = -1 + */ +int pip_index_provides(const char *index_url, const char *name, const char *version); + #endif //STASIS_CONDA_H -- cgit
