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>

2016-01-04Do not warn about missing files in NoExtractAllan McRae
The CheckSpace option checks the size of all files in a package being replaced and gives a warning when it can not read the file. However, files in NoExtract are expected to be missing and should not be warned about. Fixes FS#47470. 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.

2012-06-25diskspace: only load filesystem info on demandDave Reisner
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.

2012-06-25diskspace: dedupe code for loading FS usageDave Reisner

2012-02-19diskspace: ensure we match only full path componentsDan McGee
If one had a mountpoint at '/e' (don't ask), a file being installed to '/etc' would map to it incorrectly. Ensure we do more than just prefix matching on paths by doing some more sanity checks once the simple strncmp() call succeeds. Signed-off-by: Dan McGee <dan@archlinux.org>

2012-01-19Add diskspace checking support for Solaris/IllumosDan McGee
Was able to get my hands on one of these boxes today, so add yet another new way of doing this. I'm glad these calls are so standardized. This was compile tested on Linux and Illumos and seems to still be working in both places. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-21include config.h via MakefilesDave Reisner
Ensures that config.h is always ordered correctly (first) in the includes. Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.

2011-10-17diskspace: create static function mount_point_list_freeDave Reisner

2011-10-17diskspace: add _alpm_check_downloadspace()Dave Reisner
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>

2011-09-07Use more correct integer types in diskspace checksDan McGee
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-02Former transaction callback rename refactorDan McGee
Put all the callback stuff in alpm.h in one spot, and make the following renames for clarity with the new structure: ALPM_TRANS_EVT_* --> ALPM_EVENT_* ALPM_TRANS_CONV_* --> ALPM_QUESTION_* ALPM_TRANS_PROGRESS_* --> ALPM_PROGRESS_* alpm_option_get_convcb() --> alpm_option_get_questioncb() alpm_option_set_convcb() --> alpm_option_set_questioncb() Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-02Move all callbacks up to the handle levelDan McGee
This was just disgusting before, unnecessary to limit these to only usage in a transaction. Still a lot of more room for cleanup but we'll start by attaching them to the handle rather than the transaction we may or may not even want to use these callbacks.

2011-07-21Convert package filelists to an array instead of linked listDan McGee
This accomplishes quite a few things with one rather invasive change. 1. Iteration is much more performant, due to a reduction in pointer chasing and linear item access. 2. Data structures are smaller- we no longer have the overhead of the linked list as the file struts are now laid out consecutively in memory. 3. Memory allocation has been massively reworked. Before, we would allocate three different pieces of memory per file item- the list struct, the file struct, and the copied filename. What this resulted in was massive fragmentation of memory when loading filelists since the memory allocator had to leave holes all over the place. The new situation here now removes the need for any list item allocation; allocates the file structs in contiguous memory (and reallocs as necessary), leaving only the strings as individually allocated. Tests using valgrind (massif) show some pretty significant memory reductions on the worst case `pacman -Ql > /dev/null` (366387 files on my machine): Before: Peak heap: 54,416,024 B Useful heap: 36,840,692 B Extra heap: 17,575,332 B After: Peak heap: 38,004,352 B Useful heap: 28,101,347 B Extra heap: 9,903,005 B Several small helper methods have been introduced, including a list to array conversion helper as well as a filelist merge sort that works directly on arrays.
