2018-05-14Remove all modelines from the projectEli Schwartz
Many of these are pointless (e.g. there is no need to explicitly turn on spellchecking and language dictionaries for the manpages by default). The only useful modelines are the ones enforcing the project coding standards for indentation style (and "maybe" filetype/syntax, but everything except the asciidoc manpages and makepkg.conf is already autodetected), and indent style can be applied more easily with .editorconfig Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>

2014-08-03filelist_intersection: manually compare pathsAndrew Gregory
Prevents the need to modify paths, removing strndup as an unchecked point of failure, and lengths only need to be calculated if the paths match. Also removed an old comment regarding directory/symlink compatibility. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2014-01-28Remove ts and sw from vim modeline when noet is setFlorian Pritz
Forcing vim users to view files with a tabstop of 2 seems really unnecessary when noet is set. I find it much easier to read code with ts=4 and I dislike having to override the modeline by hand. Command run: find . -type f -exec sed -i '/vim.* noet/s# ts=2 sw=2##' {} + Signed-off-by: Florian Pritz <bluewind@xinu.at> Signed-off-by: Allan McRae <allan@archlinux.org>

This commit: -- replaces space-based indents with tabs per the coding standards -- removes extraneous whitespace (e.g. extra spaces between function args) -- adds missing braces for a one-line if statement Signed-off-by: Jason St. John <jstjohn@purdue.edu>

2013-02-24add SYMEXPORT to alpm_filelist_containsAndrew Gregory
alpm_filelist_contains is listed in alpm.h and should be public but was not exported. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2013-02-24use resolved_path for filelist_containsAndrew Gregory
alpm_filelist_contains was being used to search for resolved paths, but searching in the unresolved paths, causing it to miss matches. We always search unresolved paths and search the resolved paths if available because _alpm_filelist_resolve is not public and requires a context handle, so it can't be called from alpm_filelist_contains.

2013-02-24return resolved paths from filelist_differenceAndrew Gregory
We were comparing files based on resolved paths but returning the original file_t structures, which were not necessarily in the same order. The extra file_t information was only being used to determine if the file was a directory which can be accomplished by testing for a trailing slash, so just return the resolved path.

2013-02-24return resolved paths from filelist_intersectionAndrew Gregory
We were comparing files based on resolved paths but returning the original file_t structures, which were not necessarily in the same order. The additional file_t information was never used, so just return the resolved path. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

2012-12-14It turns out we do care about directories...Allan McRae
This is a bug that has been around since at least 2007. On a package upgrade (either by -S or -U) a new directory could overwrite any file. This is caused by the filelist difference calculation ignoring all directories and thus no new directories were checked for conflicting files on the filesystem. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14_alpm_filelist_resolve: add useful return codeAndrew Gregory
Return -1 if a path is too long to resolve or we run out of memory. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14Avoid upgrade conflict with unchanged effective pathAllan McRae
This applies to a case such as when /lib is a symlink to /usr/lib. If a package is installed which contains /lib/libfoo.so, pacman will complain if this package is then "fixed" to contain /usr/lib/libfoo.so. Since these have the same effective path and it exists within the same package, ignore the conflict. Fixes FS#30681. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14Resolve file paths during inter-package conflict checkAllan McRae
File paths are resolved if necessary during inter-package conflict checks so that packages carrying the same effective file due to directory symlinks on the filesystem are flagged as conflicting. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14_alpm_filelist_resolve: use original filenames where possibleAndrew Gregory
If a filename isn't resolved, the original can be used instead of strdup()ing it. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14Add _alpm_filelist_resolveAndrew Gregory
The _alpm_filelist_resolve function takes a filelist and creates a list with any symlinks in directory paths resolved. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2012-12-14Detect inter-package conflicts between files and directoriesAllan McRae
Detect a conflict between a file/symlink in one package and a directory in another when both are being installed at once. A side effect is the creation of conflicts between a directory symlink and a real directory (e.g lib -> usr/lib in pkg1 and /lib in pkg2). Given we can not guarantee pkg1 is installed before pkg2, this is a genuine conflict. Signed-off-by: Allan McRae <allan@archlinux.org>
2012-08-02Split _alpm_filelist_operation functionAllan McRae
To improve conflict checking, we will need to make these functions diverge to an extent where having two separate functions will be preferable. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-08-02Move filelist functions into separate source fileDan McGee
We have a few of these and might as well gather them together. This also cleans up the code a bit by using an enum instead of integer values, as well as makes a "search for file in filelist" function public so frontends can do better than straight linear search of the filelists.
