* diskspace: only load filesystem info on demandDave Reisner2012-06-25
| | | | | | | | | | | | | | | | Only load filesystem details for the mount points that we're actually going to write to. This reduces our syscall count considerably. In the case of installation, we would actually stat every mountpoint twice (an extra round for download diskspace) which means (on my system) a total of 60 syscalls to write to 3 partitions when installing the kernel package. This change reduces the 60 syscalls down to the expected 3. A slight debug output change is added here to discern between a mountpoint added to our linked list versus when we actually load the fs info.

* diskspace: add _alpm_check_downloadspace()Dave Reisner2011-10-17
| | | | | | | | | This function determines if the given cachedir has at least the given amount of free space on it. This will be later used in the sync code to preemptively halt downloads. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
* Use more correct integer types in diskspace checksDan McGee2011-09-07
| | | | | | | | | | | | | | | | This adjusts type usage to match POSIX provided types from <sys/types.h> rather than assuming everything will fit in a long or unsigned long. Use fsblkcnt_t (unsigned) and blkcnt_t (signed) as appropriate. These are affected the same way off_t is on 32 bit platforms, where the types are extende to 64 bits if large file support is enabled. Because most numbers here are block counts, this isn't near as pressing as using a 32-bit variable for file sizes where anything over 2GiB can burn you; we likely can support files at least 512 but mainly 4096 times larger.

* diskspace: allow used flag to be toggled for both remove and installDan McGee2011-02-11
| | | | | | | | | | | | | | Turn it into an enum rather than a boolean, and use a bitmask like we do for reading DB entries. The relevant flag is turned on in our two calculate loops, and anything reading the used flag later can decided which flag (or either) is relevant. This will allow the read-only partition code to be triggered on a remove-only operation, e.g. if /boot was read-only and one tried to remove grub in a sync transaction. Of course, right now, we don't actually run the diskspace check code in the '-R' codepath. Signed-off-by: Dan McGee <dan@archlinux.org>
* Check mountpoint read-only status when checking spaceDan McGee2011-02-11
| | | | | | | | | | | This is a bit of a stopgap solution for the problem, but an easier one than revamping the file conflict checking code to support the same stuff. Using some more gross autoconf magic, figure out which struct field we need to look at to determine read-only status and store that on our mountpoint struct. If we find out we needed this partition after calculating size requirements, then toss an error. Signed-off-by: Dan McGee <dan@archlinux.org>
* Skip diskspace checking for symlinks and directories in all casesDan McGee2011-02-08
| | | | | | | | | | | | | | | | | | We did this in some but not all cases, assuming the 0 value coming out of libarchive would not be a problem. However, this does not work for "fake" filesystems such as rpc_pipefs, which reports a free block and total block count of zero. Fix this by not ever counting symlinks or directories, and adding a note explaining that if we someday do count directories, their size needs to be attributed to the proper place. This patch also includes a few cleanups/performance tweaks- avoid calling strlen() on the mountpoint directory string as much by storing this size in our mountpoint struct, and push the snprintf() call up to the calculate functions since we were already doing it here in the remove case.

* Refactor statfs/statvfs type checkDan McGee2010-12-12
| | | | | | | | | | | 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.

* Add function for listing system mount pointsAllan McRae2010-12-12
| | | | | | | | | | | 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>
