◆ _package_changelog_close()

static int _package_changelog_close	(	const alpm_pkg_t UNUSED *	pkg,
		void *	fp )

static

Close a package changelog for reading.

Similar to fclose in functionality, except that the 'file stream' is from an archive.

Parameters

pkg	the package (file) that the changelog was read from
fp	a 'file stream' to the package changelog

Returns: whether closing the package changelog stream was successful

◆ _package_changelog_open()

static void * _package_changelog_open ( alpm_pkg_t * pkg )

static

Open a package changelog for reading.

Similar to fopen in functionality, except that the returned 'file stream' is from an archive.

Parameters

pkg	the package (file) to read the changelog

Returns: a 'file stream' to the package changelog

◆ _package_changelog_read()

static size_t _package_changelog_read	(	void *	ptr,
		size_t	size,
		const alpm_pkg_t UNUSED *	pkg,
		void *	fp )

static

Read data from an open changelog 'file stream'.

Similar to fread in functionality, this function takes a buffer and amount of data to read.

Parameters

ptr	a buffer to fill with raw changelog data
size	the size of the buffer
pkg	the package that the changelog is being read from
fp	a 'file stream' to the package changelog

Returns: the number of characters read, or 0 if there is no more data

◆ add_entry_to_files_list()

static int add_entry_to_files_list	(	alpm_filelist_t *	filelist,
		size_t *	files_size,
		struct archive_entry *	entry,
		const char *	path )

static

Add a file to the files list for pkg.

Parameters

pkg	package to add the file to
files_size	size of pkg->files.files
entry	archive entry of the file to add to the list
path	path of the file to be added

Returns: <0 on error, 0 on success

◆ build_filelist_from_mtree()

static int build_filelist_from_mtree	(	alpm_handle_t *	handle,
		alpm_pkg_t *	pkg,
		struct archive *	archive )

static

Generate a new file list from an mtree file and add it to the package.

An existing file list will be free()d first.

archive should point to an archive struct which is already at the position of the mtree's header.

Parameters

handle
pkg	package to add the file list to
archive	archive containing the mtree

Returns: 0 on success, <0 on error

◆ get_file_pkg_ops()

static const struct pkg_operations * get_file_pkg_ops ( void )

static

Package file operations struct accessor.

We implement this as a method because we want to reuse the majority of the default_pkg_ops struct and add only a few operations of our own on top.

◆ handle_simple_path()

static int handle_simple_path	(	alpm_pkg_t *	pkg,
		const char *	path )

static

Handle the existence of simple paths for _alpm_load_pkg_internal()

Parameters

pkg	package to change
path	path to examine

Returns: 0 if path doesn't match any rule, 1 if it has been handled

Referenced by build_filelist_from_mtree().

◆ parse_descfile()

static int parse_descfile	(	alpm_handle_t *	handle,
		struct archive *	a,
		alpm_pkg_t *	newpkg )

static

Parses the package description file for a package into a alpm_pkg_t struct.

Parameters

archive	the archive to read from, pointed at the .PKGINFO entry
newpkg	an empty alpm_pkg_t struct to fill with package info

Returns: 0 on success, -1 on error
