* Be more robust when copying package dataDan McGee2011-08-19
| | | | | | | | | | | | | | | | This changes the signature of _alpm_pkg_dup() to return an integer error code and provide the new package in a passed pointer argument. All callers are now more robust with checking the return value of this function to ensure a fatal error did not occur. We allow load failures to proceed as otherwise we have a chicken and egg problem- if a 'desc' local database entry is missing, the best way of restoring said file is `pacman -Sf --dbonly packagename`. This patch fixes a segfault that was occurring in this case. Fixes the segfault reported in FS#25667. Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove usages of alpm_list_next() in backendDan McGee2011-08-18
| | | | | | | Another function call that can be replaced by a single pointer dereference. Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove use of no-op accessor functions in libraryDan McGee2011-08-18
| | | | | | | | | The functions alpm_db_get_name(), alpm_pkg_get_name(), and alpm_pkg_get_version() are not necessary at all, so remove the calling and indirection when used in the backend, which makes things slightly more efficient and reduces code size.

* Enhance and utilize database status flagsDan McGee2011-08-18
| | | | | | | | | | | | | | | | | | * Move is_local standalone field to status enum * Create VALID/INVALID flag pair * Create EXISTS/MISSING flag pair With these additional fields, we can be more intelligent with database loading and messages to the user. We now only warn once if a sync database does not exist and do not continue to try to load it once we have marked it as missing. The reason for the flags existing in pairs is so the unknown case can be represented. There should never be a time when both flags in the same group are true, but if they are both false, it represents the unknown case. Care is taken to always manipulate both flags at the same time.

* Parse conflicts/provides/replaces at database load timeDan McGee2011-08-15
| | | | | | | | | | | | | | | | | | | | | | We did this with depends way back in commit c244cfecf654d3 in 2007. We can do it with these fields as well. Of note is the inclusion of provides even though only '=' is supported- we'll parse other things, but no guarantees are given as to behavior, which is more or less similar to before since we only looked for the equals sign. Also of note is the non-inclusion of optdepends; this will likely be resolved down the road. The biggest benefactors of this change will be the resolving code that formerly had to parse and reparse several of these fields; it only happens once now at load time. This does lead to the disadvantage that we will now always be parsing this information up front even if we never need it in the split form, but as these are uncommon fields and our parser is quite efficient it shouldn't be a big concern.

* Validate the sha256sum if availableDan McGee2011-08-15
| | | | | | Adjust load_internal() to check the sha256sum value if we have it. Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove checksum access indirectionDan McGee2011-08-15
| | | | | | | | | These items are never present in anything but sync databases, nor do we even try to load them from the local database. Remvoe the indirection meant to allow the caching layer to work since it will never do anything anyway. Signed-off-by: Dan McGee <dan@archlinux.org>
* Load and allow access to sha256sumDan McGee2011-08-15
| | | | | | | | | This adds a field in the package struct for this checksum type as well as allowing access via the API to it. The frontend is now able to display any read value. Note that this does not implement any use or verification of the value internally. Signed-off-by: Dan McGee <dan@archlinux.org>

* Depend on name_hash being setDan McGee2011-08-09
| | | | | | | This is a fairly valid assumption at this point, or at least as good of one as assuming packages all have names. Signed-off-by: Dan McGee <dan@archlinux.org>
* Convert package filelists to an array instead of linked listDan McGee2011-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Make local_db_read() private to the local backendDan McGee2011-06-30
| | | | | | | | | | | | | | | | | | | There is little need to expose the guts of this function even within the library. Make it static in be_local.c, and clean up a few other things since we know exactly where it is being called from: * Remove unnecessary origin checks in _cache_get_*() methods- if you are calling a cache method your package type will be correct. * Remove sanity checks within local_db_read() itself- packages will always have a name and version if they get this far, and the package object will never be NULL either. The one case calling this from outside the backend was in add.c, where we forced a full load of a package before we duplicated it. Move this concern elsewhere and have pkg_dup() always force a full package load via a new force_load() function on the operations callback struct. Signed-off-by: Dan McGee <dan@archlinux.org>

* Fix several -Wshadow warningsDan McGee2011-06-27
| | | | | | | | | | Only one of these looked like a real red flag, in find_requiredby(), but it doesn't hurt to fix several of them up anyway. Unfortunately, we can't turn this on universally due to things like the sync(), remove(), etc. builtins which we often use as variable names. Signed-off-by: Dan McGee <dan@archlinux.org>
* Convert backup list to new pmbackup_t typeDan McGee2011-06-22

* Ensure handle is valid and pm_errno is reset when calling into APIDan McGee2011-06-14
| | | | | | | | | | | | | | | | | We didn't do due diligence before and ensure prior pm_errno values weren't influencing what happened in further ALPM calls. I observed one case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that flag persisting the entire time we were calling library code. Add a new CHECK_HANDLE() macro that does two things: 1) ensures the handle variable passed to it is non-NULL and 2) clears any existing pm_errno flag set on the handle. This macro can replace many places we used the ASSERT(handle != NULL, ...) pattern before. Several other other places only need a simple 'set to zero' of the pm_errno field.

* Rein in the complexity of the signature typeDan McGee2011-04-24
| | | | | | | | | | | | | | Given that we offer no transparency into the pmpgpsig_t type, we don't really need to expose it outside of the library, and at this point, we don't need it at all. Don't decode anything except when checking signatures. For packages/files not from a sync database, we now just read the signature file directly anyway. Also push the decoding logic down further into the check method so we don't need this hanging out in a less than ideal place. This will make it easier to conditionally compile things down the road.

* | Remove indirection on get_name and get_version operationsDan McGee2011-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For a package to be loaded from any of our backends, these two fields are always required upfront. Due to this fact, we don't need them to be backend-specific operations and can just refer to the field directly. Additionally, our static (and thus private) cache package accessors had a NULL check on pkg before returning the relevant field. Eliminate this since they only way they are ever called is via the packages attached callback struct, which would have caused the NULL pointer dereference in the first place.
