2011-01-10Ensure we use local package when calculating removed sizeDan McGee1-5/+7
We were checking if a package existed locally, but then using the incoming package to calculate removed size rather than the currently installed package. Also adjust the local variable in the replaces loop to make it more clear that we are always dealing with local packages here. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-10Remove need for floating point division in backendDan McGee1-10/+10
All of these can be done with integer division; the only slightly interesting part is ensuring we round up like before with calling the ceil() function. We can also remove the math library from requirements; now that the only ceil() calls are gone, we don't need this anymore. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-08Fix some more simple conversion "errors"Dan McGee1-10/+10
None of these warn at the normal "-Wall -Werror" level, but casts do occur that we are fine with. Make them explicit to silence some warnings when using "-Wconversion". Signed-off-by: Dan McGee <dan@archlinux.org>
2011-01-08Use size_t for alpm_list sizesAllan McRae1-3/+3
There is a lot of swtiching between size_t and int for alpm_list sizes in the codebase. Start converting these to all be size_t by adjusting the return type of alpm_list_count and fixing all additional warnings given by -Wconversion that are generated by this change. Dan: a few more small changes to ensure things compile, adjusting some printf format string characters to accommodate the larger size on x86_64.

2010-12-21Only check diskspace availability if needs more than zeroAllan McRae1-1/+2
The amount of diskspace needed for a transaction can be less than zero. Only test this against the available disk space if it is positive, which avoids a comparison being made between signed and unsigned types (-Wsign-compare).

2010-12-15Add a cushion for diskspace checkingDan McGee1-3/+8
It is the minimum of 5% of disk capacity or 20 MiB on a per-partition basis. Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-13diskspace style cleanups and small fixesDan McGee1-48/+53
* Use our normal return() function syntax * Rework a few things to reduce number of casts * Fix void function argument declaration * Add missing gettext _() call * Remove need for seperate malloc() of statvfs/statfs structure * Unify argument order of static functions- mountpoints now always passed first * Count all files that start with '.' in a package against the DB * Rename db to db_local in check_diskspace to clarify some code * Fix some line wrapping to respect 80 characters Signed-off-by: Dan McGee <dan@archlinux.org> Signed-off-by: Allan McRae <allan@archlinux.org>
2010-12-13Refactor statfs/statvfs type checkDan McGee1-34/+17
Turn it into a configure-type typedef, which allows us to reduce the amount of duplicated code and clean up some #ifdef magic in the code itself. Adjust some of the other defined checks to look at the headers available rather than trying to pull in the right ones based on configure checks.

2010-12-13Display progress bar for disk space checkingAllan McRae1-2/+17
Checking disk space needed for a transaction can take a while so add an informative progress bar. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-13Implement disk space checkingAllan McRae1-1/+42
Pull together the work of the previous commits to implement a check for enough free space before performing an install transaction. Abort if there is not enough free space with an appropriate pm_errno.. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-13Add functions to calculate approximate disk usage by packagesAllan McRae1-0/+100
Two helper function are added to calculate the disk usage from packages that are either currently installed on the system or from a package archive. Some minor approximations have been made: 1. Size for directories is not considered when removing a package from the filesystem to avoid multiple counting across packages. Also, these are reported to take zero size while installing. 2. Symlinks are reported to contribute zero size towards removal as libarchive reports them to have zero size for install. 3. Package data files (.PKGINFO, .INSTALL, .CHANGELOG) are counted towards usage on dbpath on install, but their size is not counted on package removal. 4. No handling of extra size needed for .pacsave/.pacnew files. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-13Add function to match file to mount pointAllan McRae1-0/+28
For a given file, determine which mount point it is on or will be installed to. Take into account that we might be using an alternative installation root. Add additional helper function added to sort mount point list for easier matching. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2010-12-13Add function for listing system mount pointsAllan McRae1-0/+119
Add a mount_point_list() function that attempts to portably obtain a list of system mount points and a struct to hold needed mount point information. Abort the transaction if we are unable to determine the mount points. Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
