* Refactor download payload reset and freeDan McGee2011-09-28
| | | | | | | | | | | | | | | This was done to squash a memory leak in the sync database download code. When we downloaded a database and then reused the payload struct, we could find ourselves calling get_fullpath() for the signatures and overwriting non-freed values we had left over from the database download. Refactor the payload_free function into a payload_reset function that we can call that does NOT free the payload itself, so we can reuse payload structs. This also allows us to move the payload to the stack in some call paths, relieving us of the need to alloc space. Signed-off-by: Dan McGee <dan@archlinux.org>
* Initialize cURL library on first useDan McGee2011-09-28
| | | | | | | | | Rather than always initializing it on any handle creation. There are several frontend operations (search, info, etc.) that never need the download code, so spending time initializing this every single time is a bit silly. This makes it a bit more like the GPGME code init path. Signed-off-by: Dan McGee <dan@archlinux.org>
* Track unresolvable transaction packagesDan McGee2011-09-28
| | | | | | | | | | | | | Rather than free them right away, keep the list on the transaction as we already do with add and remove lists. This is necessary because we may be manipulating pointers the frontend needs to refer to packages, and we are breaking our contract as stated in the alpm_add_pkg() documentation of only freeing packages at the end of a transaction. This fixes an issue found when refactoring the package list display code. Signed-off-by: Dan McGee <dan@archlinux.org>
* Move pacsave path construction code off the stackDan McGee2011-09-28
| | | | | | | This is definitely not in the normal hot path, so we can afford to do some temporary heap allocation here. Signed-off-by: Dan McGee <dan@archlinux.org>
* Use the full buffer when computing md5/sha256 sumsDan McGee2011-09-28
| | | | | | | | | | | | | | | No wonder these were slower than expected. We were only reading 4 (32-bit) or 8 (64-bit) bytes at a time and feeding it to the hash functions. Define a buffer size constant and use it correctly so we feed 8K at a time into the hashing algorithm. This cut one larger `-Sw --noconfirm` operation, with nothing to actually download so only timing integrity, from 3.3s to 1.7s. This has been broken since the original commit eba521913d6 introducing OpenSSL usage for crypto hash functions. Boy do I feel stupid. Signed-off-by: Dan McGee <dan@archlinux.org>
* Fix memory leak in download payload->remote_nameDan McGee2011-09-28
| | | | | | | | | | | | | In the sync code, we explicitly allocated a string for this field, while in the dload code itself it was filled in with a pointer to another string. This led to a memory leak in the sync download case. Make remote_name non-const and always explicitly allocate it. This patch ensures this as well as uses malloc + snprintf (rather than calloc) in several codepaths, and eliminates the only use of PATH_MAX in the download code.

* Revert "libalpm: compare pkgname with strcoll"Dan McGee2011-09-27
| | | | | | | | | | | | | | | | | | | | This commit was made with the intent of displaying "correctly" sorted package lists to users. Here are some reasons I think this is incorrect: * It is done in the wrong place. If a frontend application wants to show a different order of packages dependent on locale, it should do that on its own. * Even if one wants a locale-specific order, almost all package names are all ASCII and language agnostic, so this different comparison makes little sense and may serve only to confuse people. * _alpm_pkg_cmp was unlike any other comparator function. None of the rest had any dependency on anything but the content of the structs being compared (e.g., they only used strcmp() or other basic comparison operators). This reverts commit 3e4d2c3aa65416487939148828afb385de2ee146. Signed-off-by: Dan McGee <dan@archlinux.org>
* _alpm_splitdep: use malloc instead of callocDan McGee2011-09-27
| | | | | | | There was only one simple to handle case where we left a field uninitialized; set it to NULL and use malloc() instead. Signed-off-by: Dan McGee <dan@archlinux.org>
* be_sync: fetch only entry mode, not full stat structDan McGee2011-09-27
| | | | | | | This saves a lot of unnecessary work since we don't need any of the other fields in the stat struct. Signed-off-by: Dan McGee <dan@archlinux.org>
* alpm_list: use malloc instead of callocDan McGee2011-09-27
| | | | | | | | | | | | In every case we were calling calloc, the struct we allocated (or the memory to be used) is fully specified later in the method. For alpm_list_t allocations, we always set all of data, next, and prev. For list copying and transforming to an array, we always copy the entire data element, so no need to zero it first. Signed-off-by: Dan McGee <dan@archlinux.org>
* Fix compilation using --without-gpgmeDan McGee2011-09-27
| | | | | | | I'm really good at breaking this on a regular basis. If only we had some sort of automated testing for this... Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove unnecessary loggerDan McGee2011-09-27
| | | | | | | This is just a wrapper function; the real function we call logs an almost identical line. Signed-off-by: Dan McGee <dan@archlinux.org>
* Delay check for repository servers until we need themDan McGee2011-09-27
| | | | | | | | | | In the sync download code, we added an early check in 6731d0a9407e for sync download server existence so we wouldn't show the same error over and over for each file to be downloaded. Move this check into the download block so we only run it if there are actually files that need to be downloaded for this repository. Signed-off-by: Dan McGee <dan@archlinux.org>
* Ensure fileconflict value is actually a stringDan McGee2011-09-26
| | | | | | | | | | When we switched to a file object and not just a simple string, we missed an update along the way here in target-target conflicts. This patch looks large, but it really comes down to one errant (char *) cast before that has been reworked to explicitly point to the alpm_file_t object. The rest is simply code cleanup. Signed-off-by: Dan McGee <dan@archlinux.org>
* Update Doxyfile and fix some documentation errors caught by DoxygenDan McGee2011-09-22
| | | | | | | A few parameters were outdated or wrongly named, and a few things were explicitly linked that Doxygen wasn't able to resolve. Signed-off-by: Dan McGee <dan@archlinux.org>
* Ensure database validity flags are set in invalid signature caseDan McGee2011-09-22
| | | | | | | We returned the right error code but never set the flags accordingly. Also, now that we can bail early, ensure we set the error code. Signed-off-by: Dan McGee <dan@archlinux.org>
* Handle key import errors correctly and with good error messagesDan McGee2011-09-22
| | | | | | | | | This adds calls to gpgme_op_import_result() which we were not looking at before to ensure the key was actually imported. Additionally, we do some preemptive checks to ensure the keyring is even writable if we are going to prompt the user to add things to it. Signed-off-by: Dan McGee <dan@archlinux.org>
* signing: be consistent with returning -1 for error casesDan McGee2011-09-22
| | | | | | | | This also fixes a segfault found by dave when key_search is unsuccessful; the key_search return code documentation has also been updated to reflect reality. Signed-off-by: Dan McGee <dan@archlinux.org>
* Regenerate message catalogs and translationsDan McGee2011-09-22
| | | | | | We've had a bit of churn since the last time this was done. Signed-off-by: Dan McGee <dan@archlinux.org>
* Translation file updates from TransifexDan McGee2011-09-22
| | | | | | | Pick up any updates before I push new source messages out to the service. Signed-off-by: Dan McGee <dan@archlinux.org>
* Add status and check for key being disabledDan McGee2011-09-22
| | | | | | | | | | Because we aren't using gpgv and a dedicated keyring that is known to be all safe, we should honor this flag being set on a given key in the keyring to know to not honor it. This prevents a key from being reimported that a user does not want to be used- instead of deleting, one should mark it as disabled. Signed-off-by: Dan McGee <dan@archlinux.org>
* Implement PGP key search and importDan McGee2011-09-22
| | | | | | | | | | | | | | | Add two new static methods, key_search() and key_import(), to our growing list of signing code. If we come across a key we do not have, attempt to look it up remotely and ask the user if they wish to import said key. If they do, flag the validation process as a potential 'retry', meaning it might succeed the next time it is ran. These depend on you having a 'keyserver hkp://foo.example.com' line in your gpg.conf file in your gnupg home directory to function. Signed-off-by: Dan McGee <dan@archlinux.org>

* Add _alpm_process_siglist() logic to failed package validationDan McGee2011-09-22
| | | | | | | | | | | | | | | | | | This moves the result processing out of the validation check loop itself and into a new loop. Errors will be presented to the user one-by-one after we fully complete the validation loop, so they no longer overlap the progress bar. Unlike the database validation, we may have several errors to process in sequence here, so we use a function-scoped struct to track all the necessary information between seeing an error and asking the user about it. The older prompt_to_delete() callback logic is still kept, but only for checksum failures. It is debatable whether we should do this at all or just delegate said actions to the user. Signed-off-by: Dan McGee <dan@archlinux.org>
* Add new import key question enum value and stub frontend functionDan McGee2011-09-22
| | | | | | | | This is for eventual use by the PGP key import code. Breaking this into a separate commit now makes the following patches a bit easier to understand. Signed-off-by: Dan McGee <dan@archlinux.org>
* 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>
