* libalpm: never attempt to remove a mountpointDave Reisner2013-02-16
| | | | | | | | | | | | | | | | | | | | | | | Arch Linux typically runs into this with /sys when upgrading the filesystem package in build chroots, but LXC users might also run into this, since their /sys is shared from the host and must, for security reasons, be mounted RO. I've neglected to add any tests for this because they would require root in order to run. Current tests all pass with this patch and I've confirmed the desired behavior in a VM. Incidentally, the first hunk of this patch (skipping can_remove_file checks for directories) resolves the case of API mountpoints being removed since they eventually fall into unlink_file and fail with "contains files". However, this patch should still be the Right Thing To Do™, as we can't possibly remove a directory that is also a mountpoint. Signed-off-by: Dave Reisner <dreisner@archlinux.org> [Allan] Do not skip checking if directories can be removed. Instead test if directories are mountpoints in can_remove_file.

* Fix registering database with non-gpgme buildsAllan McRae2013-02-13
| | | | | | | | | | We record whether the default SigLevel is set in order to add upon it for the *FileSigLevel entries. When using the only valid value of "SigLevel = Never" with non-gpgme builds, we need to ignore the ALPM_SIG_PACKAGE_SET flag when determining if we have a valid value for the database SigLevel.

* Add format attributes to all required functionsAllan McRae2013-02-13
| | | | | | | | | Fixes all clang warnings with -Wformat-literal. Also, fix genuine formating issue discovered once adding these attributes and add a cast to prevent a gcc warning. Signed-off-by: Allan McRae <allan@archlinux.org>
* Fix compilation error on clangAllan McRae2013-02-13
| | | | | | | | This also lead me to notice that in _alpm_gpgme_checksig many things were not being cleaned up. Fix this by having CHECK_ERR goto gpg_error and make the required adjustments. Signed-off-by: Allan McRae <allan@archlinux.org>

* Import key if needed when installing package from fileAllan McRae2013-02-09
| | | | | | | | When installing a package with "pacman -U" that has a detached signature, check if the needed key is in the keyring and download if necessary. Signed-off-by: Allan McRae <allan@archlinux.org>
* Prompt to delete packages with signature failsAllan McRae2013-02-09
| | | | | | | Offer to remove the bad package when a signature fails to validate as is done for checksum failures. Signed-off-by: Allan McRae <allan@archlinux.org>
* Remove retry path from signature validationAllan McRae2013-02-09
| | | | | | | | Now that the keyring is checked for all needed keys before the validation, we can not reach a point of a missing key when doing validity checks for sync operations. Signed-off-by: Allan McRae <allan@archlinux.org>
* Check keys are in keyring before package validationAllan McRae2013-02-09
| | | | | | | | | | | | Keys used to create signatures are checked for presence in the keyring before package validation is performed. Signed-off-by: Allan McRae <allan@archlinux.org> Conflicts: lib/libalpm/alpm.h Signed-off-by: Allan McRae <allan@archlinux.org>

* Add function to extract key id from signaturesAllan McRae2013-02-09
| | | | | | | This does not support all possibilities of RFC4880, but it does cover every key currently used in Arch Linux. Signed-off-by: Allan McRae <allan@archlinux.org>
* Move key importing into separate functionAllan McRae2013-02-09
| | | | | | | | This will be useful for checking the availablity of all keys before perfoming validation in sync operations and for downloading a needed key in upgrade operations. Signed-off-by: Allan McRae <allan@archlinux.org>
* Make key_in_keychain available in libraryAllan McRae2013-02-09

* Add configuration option for Upgrade operation SigLevelAllan McRae2013-02-07
| | | | | | | | | | | | | Add LocalFileSigLevel and RemoteFileSigLevel to control the signature checking for "pacman -U <file>" and "pacman -U <url>" operations respectively. The starting value for both these options is SigLevel, if it is specified in the [options] section, or the built-in system default. The specified values override and/or supplement this initial value. Note there is no distinction between setting "Required" and "PackageRequired" as there are no database options for Upgrade operations. Signed-off-by: Allan McRae <allan@archlinux.org>
* Restore libarchive 2.8.x compatibilityDan McGee2013-01-29
| | | | | | | | | | | We still call some of these 'deprecated' methods elsewhere, so this shouldn't present a problem. When we decide 2.x support is to be dropped, we should update all of the code to not call deprecated methods. Allan: Adjusted with respect to previous patches adding libarchive compatibilty layer.

* dload: pass back the effective URL to callers of _alpm_downloadDave Reisner2013-01-29
| | | | | | | | | | | I suspect that eventually we're going to end up returning a pointer to an allocated struct to describe the download result, but that's for another patch when the need arises...

* Make path to ldconfig configurableAllan McRae2013-01-28
| | | | | | | | | The FHS (2.3) says having ldconfig in /sbin is optional and it is usually located in /usr/sbin. So /sbin/ldconfig should not be hard coded in pacman. Instead, provide a configure option --with-ldconfig that defaults to the current path. Signed-off-by: Allan McRae <allan@archlinux.org>

* dload: avoid showing progress bars on some redirectsDave Reisner2013-01-17
| | | | | | | | | | | | | RFC 2616 doesn't forbid a 301 or 302 repsonse from having a body, and servers exist in the wild that show this behavior. In order to prevent pacman from showing a progress bar when we aren't actually downloading a package (and merely following one of these pain in the butt redirects), capture the server response code in the response header, rather than waiting to peel it off the handle after the download has finished.

* Do not use full path for ldconfigAllan McRae2013-01-17
| | | | | | | | | | | The ldconfig binary is not guaranteed to be in /sbin. Change to calling just "ldconfig" rather than using the full path. This removed the check that the ldconfig binary exists. However, it is a reasonable assumption that it will exist if its configuration file does. Signed-off-by: Allan McRae <allan@archlinux.org>
* Use execvp for running programs in chrootAllan McRae2013-01-17

* Save backup files with extension .pacsave.nPang Yan Han2013-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach pacman to save backup files with extension .pacsave.n, where n is a positive integer. The current backup file shall be saved as <name>.pacsave, while existing .pacsave.n files will be renamed to <name>.pacsave.n+1 Example: 1. You have subversion installed in your local repo. /etc/conf.d/svnserve is a file to be backed up. It contains local modifications 2. You remove subversion from your repo. /etc/conf.d/svnserve is backed up as /etc/conf.d/svnserve.pacsave 2. You install subversion again 3. You edit /etc/conf.d/svnserve 4. You remove subversion. The existing /etc/conf.d/svnserve.pacsave is renamed to /etc/conf.d/svnserve.pacsave.1 and /etc/conf.d/svnserve is backed up as /etc/conf.d/svnserve.pacsave Signed-off-by: Pang Yan Han <pangyanhan@gmail.com> Rebased from original email and adjusted for util-common usage.

* Split common utility functions for libalpm and pacmanAllan McRae2013-01-04
| | | | | | | | | | | | There is duplicated code in the util.c files in the libalpm and pacman source code. Split this into a separate file so that it can be shared via a symlink. This prevents code divergence between the two code bases. Also, move mbasename and mdirname from pacman/util.c into util-common.c in preparation for the following patch that uses them to add an extension to pacsave files.

* Do not warn about missing database if being downloadedAllan McRae2012-12-14
| | | | | | | | | When a configured repo database is not already downloaded, a warning message such as "warning: database file for 'testing' does not exist" is printed. Disable this warning when the database is scheduled to be downloaded in the transaction. Signed-off-by: Allan McRae <allan@archlinux.org>
* Fix future signature timestamp warningAllan McRae2012-12-14
| | | | | | | | | | | | The warning given for a signature timstamp being in the future compared to the system time stated the opposite. Also, move this warning to debug output. It is useless in its current form as the package or database that is giving the error is not mentioned and so other debug output is needed to find the offending signature.

* It turns out we do care about directories...Allan McRae2012-12-14
| | | | | | | | | | 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.

* Avoid upgrade conflict with unchanged effective pathAllan McRae2012-12-14
| | | | | | | | | | | | 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>
* Resolve file paths during inter-package conflict checkAllan McRae2012-12-14
