2011-10-12Introduce alpm_time_t typeDan McGee1-5/+4
This will always be a 64-bit signed integer rather than the variable length time_t type. Dates beyond 2038 should be fully supported in the library; the frontend still lags behind because 32-bit platforms provide no localtime64() or equivalent function to convert from an epoch value to a broken down time structure.

2011-09-30Use _alpm_local_db_pkgpath in _cache_changelog_openDan McGee1-4/+4
Another place where we were doing the dirty work by hand. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-30Revamp scriptlet path formation for scriptlets in local databaseDan McGee1-9/+10
Expose the current static get_pkgpath() function internally to the rest of the library as _alpm_local_db_pkgpath(). This allows use of this convenience function in add.c and remove.c when forming the path to the scriptlet location. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-19Reduce path allocation on the stack in local databaseDan McGee1-32/+35
We did a lot of both malloc-ing and stack printing to form some paths in this code. Attempt to unify it all into the one get_pkgpath() method by adding an optional third "filename" parameter, and form the necessary path string all in one go. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-19be_local: cope with a desc file without trailing newlineDan McGee1-2/+6
We checked the (fgets == NULL and !feof) case, but never actually bailed out of the loop if we were at the end of the file, causing infinite looping. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-19Remove const specifier from changelog_read() void parameterDan McGee1-1/+1
This shouldn't really be declared with const, and causes a compile error when -Wcast-qual is used. Remove the const specifier from the function specification and all implementations. Also fix one other trivial -Wcast-qual warning in _alpm_db_cmp(). Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-03More package operations cleanupDan McGee1-14/+0
Neither deltas nor filename attributes are ever present in the local database, so we can remove all of the indirection for accessing these attributes. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-03Clean up handling of size fieldsDan McGee1-15/+1
We currently have csize, isize, and size concepts, and sometimes the difference isn't clear. Ensure the following holds: * size (aka csize): always the compressed size of the package; available for everything except local packages (where it will return 0) * isize: always the installed size of the package; available for all three package types Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-30Parse > 2GiB file sizes correctlyDan McGee1-2/+2
We were using atol(), which on 32 bit, cannot handle values greater than 2GiB, which is fail. Switch to a strtoull() wrapper function tailored toward parsing off_t values. This allows parsing of very large positive integer values. off_t is a signed type, but in our usages, we never parse or have a need for negative values, so the function will return -1 on error.

2011-08-29Database read optimizationsDan McGee1-1/+7
Hard to believe there was still more room to improve on this, but I found an easily correctable oversight tonight. Our databases (both sync and local) contain many blank lines, and we were not moving onto the next line right away in these cases; instead we would proceed through our strcmp() conditional checks as normal. Some local numbers follow to show the effects of this patch: Sync `-Ss foobarbaz`: 71,709 blank lines skipped early ~1,505,889 strcmp() calls avoided (21 per line) ~15% speed improvement (.210 --> .179 sec) Local `-Qs foobarbaz`: 6,823 blank lines skipped early 115,991 strcmp() calls avoided (17 per line) ~6% speed improvement (.080 -> .071 sec) Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-29Check local database status flag in db_write sanity check blockDan McGee1-5/+1
Do all the checks at once; this also avoids the 'return' call after we have allocated memory for "pkgpath" as well as tweaked the umask. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-20Remove alpm_option_get_* usage from backendDan McGee1-2/+1
These are all available directly on the handle without indirection. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Remove use of no-op accessor functions in libraryDan McGee1-3/+2
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Enhance and utilize database status flagsDan McGee1-0/+20
* 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. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-15Parse conflicts/provides/replaces at database load timeDan McGee1-12/+19
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.

2011-08-15Remove checksum access indirectionDan McGee1-14/+0
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>
2011-08-15Load and allow access to sha256sumDan McGee1-0/+7
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>
2011-08-08Store a package info level flag if we fail to load dataDan McGee1-3/+11
If we are missing a local database file, we get repeated messages over and over telling us the same thing, rather than being sane and erroring only once. This package adds an INFRQ_ERROR level that is added to the mask if we encounter any errors on a local_db_read() operation, and short circuits future calls if found in the value. This fixes FS#25313. Note that this does not make any behavior changes other than suppressing error messages and repeated code calls to failure cases; we still have more to do in the "local database is hosed" department. Also make a small update to the wrong but unused flags set in be_package; using INFRQ_ALL there was not totally correct. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-02Don't trim whitespace when reading database entriesDan McGee1-6/+6
We don't write with extra or unknown whitespace, so there is little reason for us to trim it when reading either. This also fixes the hopefully never encountered "paths that start or end with spaces" issue, for which two pactests have been added. The tests also contain other evil characters that we have encountered before and handle just fine, but it doesn't hurt to ensure we don't break such support in the future. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-21Convert package filelists to an array instead of linked listDan McGee1-9/+32
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.

2011-07-03Move alpm filelists to a struct objectDan McGee1-5/+8
This allows us to capture size and mode data when building filelists from package files. Future patches will take advantage of this newly available information, and frontends can use it as well. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-03be_local: use macros in database loading similar to be_syncDan McGee1-77/+43

2011-06-30Add an alpm_db_get_valid() public functionDan McGee1-0/+1
This allows one to check if a database is valid or invalid. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-30Make local_db_read() private to the local backendDan McGee1-28/+17
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>

2011-06-24Make sync DB reading a bit more flexibleDan McGee1-1/+2
We can reorganize things a bit to not require reading a directory-only entry first (or at all). This was noticed while working on some pactest improvements, but should be a good step forward anyway. Also make _alpm_splitname() a bit more generic in where it stores the data it parses. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-24Add a 'valid' flag to the database objectDan McGee1-0/+6
Start by converting all of our flags to a 'status' bitmask (pkgcache status, grpcache status). Add a new 'valid' flag as well. This will let us keep track if the database itself has been marked valid in whatever fashion. For local databases at the moment we ensure there are no depends files; for sync databases we ensure the PGP signature is valid if required/requested. The loading of the pkgcache is prohibited if the database is invalid. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-24Move database 'version' check to registration timeDan McGee1-53/+58
This is another step toward doing both local database validation (ensuring we don't have depends files) and sync database validation (via signatures if present) when the database is registered. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-22Convert backup list to new pmbackup_t typeDan McGee1-4/+8
This allows us to separate the name and hash elements in one place and not scatter different parsing code all over the place, including both the frontend and backend. Signed-off-by: Dan McGee <dan@archlinux.org>

This is the last user of our global handle object. Once again the diff is large but the functional changes are not. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-14Move pm_errno onto the handleDan McGee1-19/+9

2011-06-09Require handle argument to all alpm_option_(get|set)_*() methodsDan McGee1-1/+1
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>
2011-06-07New signatures for alpm initialize and releaseDan McGee1-1/+1
These new method signatures return and take handle objects to operate on so we can move away from the idea of one global handle in the API. There is also another important change and that deals with the setting of root and dbpaths. These are now done at initialization time instead of using setter methods. This allows the library to operate more safely knowing that paths won't change underneath it. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-03Add handle attribute to pmpkg_t structDan McGee1-0/+1
Similar to what we just did for the database; this will make it easy to always know what handle a given package originated from. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Add handle attribute to pmdb_t structDan McGee1-0/+1
This is the first step in a long process to remove our dependence on the global handle variable we currently share in libalpm, with the goal to make things a bit more thread-safe and re-entrant. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Remove ALPM_LOG_FUNC macroDan McGee1-19/+0
The usefulness of this is rather limited due to it not being compiled into production builds. When you do choose to see the output, it is often overwhelming and not helpful. The best bet is to use a debugger and/or well-placed fprintf() statements. Signed-off-by: Dan McGee <dan@archlinux.org>
