* Add alpm_capabilities() method and enumerationDan McGee2011-09-22
| | | | | | | | This allows a frontend program to query, at runtime, what the library supports. This can be useful for sanity checking during config- requiring a downloader or disallowing signature settings, for example. Signed-off-by: Dan McGee <dan@archlinux.org>
* Move default siglevel value from backend to frontendDan McGee2011-09-22
| | | | | | | | | | | | | | | This takes the libraries hidden default out of the equation: hidden in the sense that we can't even find out what it is until we create a handle. This is a chicken-and-egg problem where we have probably already parsed the config, so it is hard to get the bitmask value right. Move it to the frontend so the caller can do whatever the heck they want. This also exposes a shortcoming where the frontend doesn't know if the library even supports signatures, so we should probably add a alpm_capabilities() method which exposes things like HAS_DOWNLOADER, HAS_SIGNATURES, etc. Signed-off-by: Dan McGee <dan@archlinux.org>
* validate_deltas: split verify/check errors loopsDan McGee2011-09-22
| | | | | | | | | | | | | | | | This allows us to do all delta verification up front, followed by whatever needs to be done with any found errors. In this case, we call prompt_to_delete() for each error. Add back the missing EVENT(ALPM_EVENT_DELTA_INTEGRITY_DONE) that accidentally got removed in commit 062c391919e93f1d6. Remove use of *data; we never even look at the stuff in this array for the error code we were returning and this would be much better handled by one callback per error anyway, or at least some strongly typed return values. Signed-off-by: Dan McGee <dan@archlinux.org>
* Fix possible segfault if siglist was emptyDan McGee2011-09-22
| | | | | | | | If siglist->results wasn't a NULL pointer, we would try to free it anyway, even if siglist->count was zero. Only attempt to free this pointer if we had results and the pointer is valid. Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove noisy debug loggerDan McGee2011-09-21
| | | | | | | | This one can be overwhelming when reading debug output from a very large package. We already have the output of each extracted file so we probably can do without this in 99.9% of cases. Signed-off-by: Dan McGee <dan@archlinux.org>
* _alpm_sync_commit: extract two static methodsDan McGee2011-09-20
| | | | | | | | This adds two new static methods, check_validity() and load_packages(), to sync.c which are simply code fragments pulled out of our do-everything sync commit code. Signed-off-by: Dan McGee <dan@archlinux.org>

* signing: add a process and retry loop for database signaturesDan McGee2011-09-20
| | | | | | | | | | | | | | | | | | | | | | | In reality, there is no retrying that happens as of now because we don't have any import or changing of the keyring going on, but the code is set up so we can drop this in our new _alpm_process_siglist() function. Wire up the basics to the sync database validation code, so we see something like the following: $ pacman -Ss unknowntrust error: core: signature from "Dan McGee <dpmcgee@gmail.com>" is unknown trust error: core: signature from "Dan McGee <dpmcgee@gmail.com>" is unknown trust error: database 'core' is not valid (invalid or corrupted database (PGP signature)) $ pacman -Ss missingsig error: core: missing required signature error: core: missing required signature error: database 'core' is not valid (invalid or corrupted database (PGP signature)) Yes, there is some double output, but this should be fixable in the future. Signed-off-by: Dan McGee <dan@archlinux.org>
* Allow our PGP helper method to pass back the signature resultsDan McGee2011-09-20
| | | | | | | This will make its way up the call chain eventually to allow trusting and importing of keys as necessary. Signed-off-by: Dan McGee <dan@archlinux.org>
* Split package validation and load loopsDan McGee2011-09-20
| | | | | | | | | | This adds a some new callback event and progress codes for package loading, which was formerly bundled in with package validation before. The main sync.c loop where loading occurred is now two loops running sequentially. The behavior should not change with this patch outside of progress and event display; more changes will come in following patches. Signed-off-by: Dan McGee <dan@archlinux.org>
* Extract an _alpm_pkg_validate_internal() methodDan McGee2011-09-20
| | | | | | | | | _alpm_pkg_load_internal() was becoming a monster. Extract the top bit of the method that dealt with checksum and signature validation into a separate method that should be called before one loads a package to ensure it is valid. Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove all usages of alpm_list_getdata() from the libraryDan McGee2011-09-20
| | | | | | No need for the indirection; just access ->data instead. Signed-off-by: Dan McGee <dan@archlinux.org>
* _alpm_runscriptlet(): remove clean_tmpdir variableDan McGee2011-09-20
| | | | | | | This is always true at the end since we return early if we couldn't create the tmpdir, so it is totally unnecessary. Signed-off-by: Dan McGee <dan@archlinux.org>
* Access db->pkgcache directly in db_free_pkgcache()Dan McGee2011-09-20
| | | | | | | | We shouldn't be going through the accessor that does a bunch of unnecessary legwork, including potentially loading the pkgcache right before we free it. Signed-off-by: Dan McGee <dan@archlinux.org>
* Use more efficient way of restoring working directoryDan McGee2011-09-19
| | | | | | | | | | | | Rather than using a string-based path, we can restore the working directory via a file descriptor and use of fchdir(). From the getcwd manpage: Opening the current directory (".") and calling fchdir(2) to return is usually a faster and more reliable alternative when sufficiently many file descriptors are available. Signed-off-by: Dan McGee <dan@archlinux.org>
* Reduce path allocation on the stack in local databaseDan McGee2011-09-19
| | | | | | | | | 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>
* Be smarter about running ldconfig during removal transactionsDan McGee2011-09-19
| | | | | | | | | | 1. Don't run it if something failed in package removal- this mirrors what we already do in sync transactions. 2. Don't run it if we are invoking it for the replaces removal bit of a sync transaction- it doesn't make sense to run ldconfig halfway through a sync install; we should only run it once at the end. Signed-off-by: Dan McGee <dan@archlinux.org>
* Search for non-prefixed paths in skip_remove listDan McGee2011-09-19
| | | | | | | We add them to this list with the root path not appended; we should be searching for them this way as well. Signed-off-by: Dan McGee <dan@archlinux.org>
* be_local: cope with a desc file without trailing newlineDan McGee2011-09-18
| | | | | | | | 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>
* Remove const specifier from changelog_read() void parameterDan McGee2011-09-18
| | | | | | | | | | 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>
* Remove dead changelog_feof() codeDan McGee2011-09-18
| | | | | | | We never ended up using or really needing this; kill it for now knowing it is in git history if ever needed again. Signed-off-by: Dan McGee <dan@archlinux.org>
* dload: avoid using memrchrDave Reisner2011-09-18
| | | | | | | | This function doesn't exist on OSX. Since there aren't any other candidates in alpm for which this function would make sense to use, simply replace the function call with a loop that does the equivalent. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

* account for partial delta files in download sizeDave Reisner2011-09-11
| | | | | | | | | Similar to an earlier commit which accounts for .part files for full packages, calculate the download_size for deltas keeping mind the possibility of a partial transfer. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
* make compute_download_size consider .part filesDave Reisner2011-09-11
| | | | | | | | | | | Check for the existance of a partial download of a package file before jumping to delta calculations. Currently, if there were 10MiB remaining in a 100MiB the values passed to the front end do not reflect this. Refactored from an old patch originally by Dan.

* dload: provide optional netrc supportDave Reisner2011-09-11
| | | | | | | | | if ~/.netrc exists and has credentials for the hostname requested in a download, they will be provided in an http auth request. This can still be overridden by explcitly declaring user:pass in the URL. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

* Use more correct integer types in diskspace checksDan McGee2011-09-07
| | | | | | | | | | | | | | | | 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>
* Ensure PackageRequired works as expectedDan McGee2011-09-07
| | | | | | | | | Changes in commit dc3336c277 caused this to stop working as expected for sync packages, due to the way the logic is structured. Ensure we always enter the signature code if the bitflag is flipped on to check signatures for packages. Rename 'use_sig' to 'has_sig' for clarity. Signed-off-by: Dan McGee <dan@archlinux.org>
* dload: use intmax_t when printing off_tDan McGee2011-09-06
| | | | | | This works for both 32-bit and 64-bit platforms. Signed-off-by: Dan McGee <dan@archlinux.org>
* dload: abstract dload_interrupted reasonsDave Reisner2011-09-06
| | | | | | | This gives us some amount of room to grow in case we ever find another reason that we might return with an error from the progress callback. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
* dload: improve debug outputDave Reisner2011-09-06
| | | | | | | | We lost some of this output in the fetch->curl conversion, but I also noticed in FS#25852 that we just lack some of this useful information along the way. Signed-off-by: Dave Reisner <dreisner@archlinux.org>
* avoid blowing out the filecache list when using tmpdirDave Reisner2011-09-06
| | | | | | | | | | | | | | | | _alpm_filecache_setup() destroys the list of cachedirs when it finds no writeable directories in the config. This put us in an awkward situation where _alpm_filecache_find() would locate a downloaded file in a r/o cachedir, but then fail to install it after _alpm_filecache_setup() is called (with a NULL argument). Change this behavior to merely prepend the temporary directory to the list of available cachedirs. Dan exposed it in e07547ee4ed4, as now a package can be found in a directory we may not be able to actually store packages in.

* More package operations cleanupDan McGee2011-09-02
| | | | | | | | 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>
* Former transaction callback rename refactorDan McGee2011-09-02
| | | | | | | | | | | | | 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>
* Move all callbacks up to the handle levelDan McGee2011-09-02
| | | | | | | | | 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. Signed-off-by: Dan McGee <dan@archlinux.org>
* Make delta validation/application more logicalDan McGee2011-09-02
| | | | | | | | The call to apply was tucked inside validate, and the EVENT callbacks were done outside the function rather than inside. Reorganize things a bit to make more sense. Signed-off-by: Dan McGee <dan@archlinux.org>
* Clean up handling of size fieldsDan McGee2011-09-02
| | | | | | | | | | | | 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>

* Scale package integrity progress bar/percentage by package sizeDan McGee2011-08-30
| | | | | | | | This upgrades the simple 15/17 scaling by package number we used before to package sized based scaling, which is much more accurate. Addresses some of the issues raised in FS#25817. Signed-off-by: Dan McGee <dan@archlinux.org>

* Parse > 2GiB file sizes correctlyDan McGee2011-08-29
| | | | | | | | | | | | | | | | | | | | | | 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.

* Streamline alpm_splitdep() comparisonsDan McGee2011-08-29
| | | | | | | | | | | | | | This reduces from 5 to 3 the number of searches needed on the string looking for a comparison operator, since we can so a second quick comparison looking for '=' if we find '<' or '>'. It also makes every search doable with strchr() or memchr() rather than the slower strstr() method. In testing, only 10% of splitdep calls (~1600 / 16000) during an -Ss database load found a version comparison operator, so optimizing the not found path to be require less work makes sense. Signed-off-by: Dan McGee <dan@archlinux.org>
* _alpm_splitdep(): don't pass bogus length value to strndupDan McGee2011-08-28
| | | | | | | | | If we fell through to the ALPM_DEP_MOD_ANY case, ptr would be NULL, and we would pass (0 - <str>), which is a rather large negative number or bogus positive number, depending on signed/unsigned. Just use strdup in the case where we don't have a ptr available. Signed-off-by: Dan McGee <dan@archlinux.org>
* Database read optimizationsDan McGee2011-08-28
| | | | | | | | | | | | | | | | | | | | | | 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>
