* Remove ts and sw from vim modeline when noet is setFlorian Pritz2014-01-28
| | | | | | | | | | | | 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>

* Allow UseDelta option to specify a delta ratioDan McGee2012-01-18
| | | | | | | | | | | | | | | | | Rework the frontend and backend to allow passing a ratio value in for UseDelta rather than having a hardcoded #define-d 0.7 value always used. This is useful for those with fast connections, who would likely benefit from tuning this ratio to lower values; it is also useful for general testing purposes. The libalpm API changes for this, but we do support the old config file format with a no-value 'UseDelta' option; in this case we simply use the old default of 0.7. We clamp the ratio values to a sane range between 0.0 and 2.0, allowing ratios above 1.0 for testing purposes. Signed-off-by: Dan McGee <dan@archlinux.org>
* Only compile delta regex onceDan McGee2012-01-02
| | | | | | | | | | | | | | | | | This reduces the number of regcomp() calls when parsing delta entries in the database from once per entry to once for the entire context handle by storing the compiled regex data on the handle itself. Just as we do with the cURL handle, we initialize it the first time it is needed and free it when releasing the handle. A few other small tweaks to the parsing function also take place, including using the stack to store the transient and short file size string while parsing it. When parsing a sync database with 1378 delta entries, this reduces the time of a `pacman -Sl deltas` operation by 50% from 0.22s to 0.12s. Signed-off-by: Dan McGee <dan@archlinux.org>
* include config.h via MakefilesDave Reisner2011-12-21
| | | | | | | | | | | | | | | 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.

* Correctly duplicate delta objectsDan McGee2011-06-20
| | | | | | | | We were using copy_data before; this works for the struct itself but not the strings contained within. Fix it up by duplicating all the data as we do with our other structures. Signed-off-by: Dan McGee <dan@archlinux.org>

* Require handle argument to all alpm_option_(get|set)_*() methodsDan McGee2011-06-09
| | | | | | | | This requires a lot of line changes, but not many functional changes as more often than not our handle variable is already available in some fashion. Signed-off-by: Dan McGee <dan@archlinux.org>
* Include "config.h" in header files using off_tDan McGee2011-04-15
| | | | | | | | This makes it absolutely dead easy to ensure off_t has the same length in all compilation units. I just spent 2.5 hours bashing my head on an issue related to this so damn it I'm fixing it for good. Signed-off-by: Dan McGee <dan@archlinux.org>

* libalpm: remove from_md5 and to_md5 from pmdelta_tXavier Chantry2009-02-28
| | | | | | | | | | | | | The from_md5 and to_md5 fields were a nice extra safety, which would avoid trying to apply deltas on corrupted package files. However, they are not strictly necessary, since xdelta should be able to detect that on its own. The main problem is that it is impossible to compute these informations from the delta only. So repo-add would not be able to compute the delta entry based on just the delta file. Signed-off-by: Xavier Chantry <shiningxc@gmail.com> Signed-off-by: Dan McGee <dan@archlinux.org>
* Use correct C type for file sizesDan McGee2008-06-04
| | | | | | | | | | | | | | We have been using unsigned long as a file size type for a while, which works but isn't quite correct and could easily break. Worse was probably our use of int in the download callback functions, which could be restrictive for packages > 2GB in size. Switch all file size variables to use off_t, which is the preferred type for file sizes. Note that at least on Linux, all applications compiled against libalpm must now be sure to use large file support, where _FILE_OFFSET_BITS is defined to be 64 or there will be some weird issues that crop up.

* Completely rework delta algorithmChantry Xavier2008-04-26
| | | | | | | | | | | | | | | | | | | | Using the graph structures that Nagy set up for dependency sorting, we now do a similar process for deltas. Load up all of the deltas into a graph object on which we can then apply Dijkstra's algorithm, using the new weight field of graph struct. We initialize the nodes weight using the base files that we can use in our filecache (both filename and md5sum must match). The algorithm then picks the best path among those that can be resolved. Note that this algorithm has a few advantages over the old one: 1. It is completely file agnostic. These delta chains do not have to consist of package files- this could be adopted to do delta-fied DBs. 2. It does not use the local_db anymore, or even care if a package or file is currently installed. Instead, it only looks in the filecache for files and packages that match delta chain entries.

* Rework delta struct and modify code accordinglyDan McGee2008-04-26
| | | | | | | | | | Start to move the delta struct away from an assumed package name scheme and towards something that is package (or even filename) agnostic. This will allow us much greater flexibility in the usage of deltas (maybe even sync DBs some day) as well as allowing code outside of delta.h/delta.c to be much cleaner with less of a need for snprintf() calls.

* Convert deltas to dynamic allocationDan McGee2008-01-21
| | | | | | | | Another elimination of a static length structure in libalpm. Should result in a little more memory saved during execution of packages with lots of deltas attached. Signed-off-by: Dan McGee <dan@archlinux.org>
