2014-09-23wrap fgets to retry on EINTRAndrew Gregory1-7/+7
The read() underlying fgets() can be interrupted by a signal handler causing fgets() to return NULL. Before we started handling SIGWINCH, the odds of interrupting a read were low and typically resulted in termination anyway. Replace all fgets calls with a wrapper that retries in EINTR.

2014-09-23Check the version of the local database during validationAllan McRae1-18/+11
When we check the database version directly, there is no longer a need to scan for depends files. Signed-off-by: Allan McRae <allan@archlinux.org>
2014-09-23Add version file to empty local databaseAllan McRae1-12/+32
If a user manually creates the local database directory, or has an empty local database for some other reason, we silently add a version file Signed-off-by: Allan McRae <allan@archlinux.org>
2014-09-23Add version file when creating local database directoryAllan McRae1-0/+18
The version of the local pacman database is stored in its root in the file ALPM_DB_VERSION. The version is starting at 9, corresponding to the next libalpm library version. Signed-off-by: Allan McRae <allan@archlinux.org>
2014-09-23Create local database directory if it is missingAllan McRae1-14/+26
This means that a missing local database becomes an error (as it should be immediately created). Note this only creates the "local" directory and not its parent, which is checked for during locking. Signed-off-by: Allan McRae <allan@archlinux.org>
2014-03-08Use MALLOC throughtout libalpmAllan McRae1-5/+1
Use MALLOC instead of malloc for safety in libalpm. Some changes are pure refactoring, but for others this provides a success check for memory allocation. Signed-off-by: Allan McRae <allan@archlinux.org>

2014-01-30local_db_populate: initialize empty pkgcacheAndrew Gregory1-0/+1
If the db directory did not exist when local_db_populate was called, the pkgcache wouldn't be initialized, causing pkghash_add_pkg to fail. Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>
2014-01-28Remove ts and sw from vim modeline when noet is setFlorian Pritz1-1/+1
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.

2013-09-04libalpm: introduce a usage level for reposDave Reisner1-0/+1
This defines a level of interest a user has in a repository. These are described by the bitmask flags in the alpm_db_usage_t enum: ALPM_DB_USAGE_SEARCH: repo is valid for searching ALPM_DB_USAGE_INSTALL: repo is valid for installs (e.g. -S pkg) ALPM_DB_USAGE_UPGRADE: repo is valid for sysupgrades ALPM_DB_USAGE_ALL: all of the above are valid Explicitly listing the contents of a repo will always be valid, and the repo will always be refreshed appropriately on sync operations.

2013-01-29Restore libarchive 2.8.x compatibilityDan McGee1-1/+1
We still call some of these 'deprecated' methods elsewhere, so this shouldn't present a problem. When we decide 2.x support is to be dropped, we should update all of the code to not call deprecated methods. Allan: Adjusted with respect to previous patches adding libarchive compatibilty layer.

2012-08-02Move filelist functions into separate source fileDan McGee1-0/+1
We have a few of these and might as well gather them together. This also cleans up the code a bit by using an enum instead of integer values, as well as makes a "search for file in filelist" function public so frontends can do better than straight linear search of the filelists. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-08-01lib/be_local: ensure local filelists are sortedDave Reisner1-0/+2

2012-06-26add line length parameter to _alpm_strip_newlineDave Reisner1-7/+7
If known, callers can pass the line size to this function in order to avoid an strlen call. Otherwise, they simply pass 0 and _alpm_strip_newline will do the call instead. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2012-04-30Convert ALLOC_FAIL macro into a functionDan McGee1-2/+2
This path is rarely (read: never) taken in any normal run of the code, so injecting the fprintf() call everywhere with the macro is a bit overkill. Instead, add a lightweight _alpm_alloc_fail() function that gets called instead. This does have a reasonable effect on the size of the generated code; most places using the macros provided by util.c have their code size reduced. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-04-30be_local: use the right length value for filename in all casesDan McGee1-2/+3
Increment the strlen() provided value by 1 for the NULL byte so we use the right value in all three places we later reference it. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-04-25be_local: write all single-valued attributes firstDan McGee1-18/+20
There isn't a whole lot of reason other than code clarity for this, but it makes it a bit more obvious where multivalued attributes start. Signed-off-by: Dan McGee <dan@archlinux.org>

2012-03-16Prefer fputs/fputc over fprintf when writing local databaseDan McGee1-11/+15
Using fputs should be faster as no format string parsing is required. It also prevents silly errors related to unescaped '%' signs, and removes the need to double them up in a lot of places. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-03-16Extract a write_deps function from local database writingDan McGee1-45/+22
This reduces a lot of code duplication in the write function, which cleans it up a bit. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-03-16Remove unnecessary path check from local databaseDan McGee1-12/+3
This removes a call to _alpm_local_db_pkgpath() as well as an access() call when reading the local database. This appears to be code from 2006 that has stuck around. We don't need it because: 1) We never use this path except to check it via access(); however, we are already in a readdir() loop so it exists, or at least did at the time of the call. 2) The fopen() and other calls will fail on accessing the database files anyway, and we need to check those for errors. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-03-09Add information on how an installed package was validatedAllan McRae1-0/+43
When installing a package, store information on which validation method was used and output this on "pacman -Qi" operations. e.g. Validated By : SHA256 Sum Possible values are Unknown, None, MD5 Sum, SHA256 Sum, Signature.

2012-02-06ALPM API adjustments for sanity and consistencyDan McGee1-0/+24
This makes several small adjustments to our exposed method names, and in one case, parameters. The justification here is to make methods less odd in their naming convention. If a method takes an alpm_db_t argument, the method should be named 'alpm_db_*', but perhaps more importantly, if it doesn't take a database as the first parameter, it should not. Summary of changes: alpm_db_register_sync -> alpm_register_syncdb alpm_db_unregister_all -> alpm_unregister_all_syncdbs alpm_option_get_localdb -> aplpm_get_localdb alpm_option_get_syncdbs -> aplpm_get_syncdbs alpm_db_readgroup -> alpm_db_get_group alpm_db_set_pkgreason -> alpm_pkg_set_reason All methods keep the same argument list except for alpm_pkg_set_reason; there we drop the 'handle' argument as it can be retrieved from the passed in package object.

2012-01-23Remove rmrf implementation from backendDan McGee1-5/+35
This moves the code for removal of local database entries right into be_local.c, which was the last user of the rmrf() function we had in our utility source file. We can simplify the implementation and make it non-recursive as we know the structure of the local database entries. Signed-off-by: Dan McGee <dan@archlinux.org>
2012-01-03pkghash improvements/modificationsDan McGee1-2/+1
This patch changes a variety of small things related to our pkghash implementation with an eye toward performance, especially on native 32-bit systems. * Use `unsigned int` rather than `size_t` for hash sizes. We already return ERANGE for any attempted creation of a hash greater than 1 million elements, so unsigned int is more than large enough for our purposes. Switching to this type allows 32 bit systems to do native math without helper functions from libgcc. * _alpm_pkghash_create() now internally adds extra padding for additional array elements, rather than that being the responsibility of the caller. * #define values are moved into static const values in pkghash.c; a new `stride` value is also extracted (but remains set at 1). * Division and modulus operators are removed from the normal find and add paths if possible. We store the upper limit of the number of elements in the hash so we no longer need to calculate this every element addition. When doing wraparound position calculations, we only apply the modulus operator if the value is greater than the number of buckets. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-12-22include config.h via MakefilesDave Reisner1-2/+0
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.

2011-12-07Slight local database files reading optimizationDan McGee1-5/+13
Since we know the length of the line, we can use this all the way through and do a cheaper operation than strdup() by just invoking malloc and memcpy directly. Signed-off-by: Dan McGee <dan@archlinux.org>
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.

2011-09-30Revamp 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

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>

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.
