* Update string catalogs after string tweaksDan McGee2011-08-09
| | | | | | | | | This also pulls in some early translations we had entered in Transifex in the last day so those would not be lost. The diffstat is huge and not very telling as usual, as all sorts of fuzzyness switches happened this time around for some reason. Signed-off-by: Dan McGee <dan@archlinux.org>
* Don't walk off front of string when stripping newlineDan McGee2011-08-09
| | | | | | | | If the string was zero-length to begin with, or consists of only newline characters, nothing stopped us from incrementing right off the front of the string. Ensure len stays above zero the whole time. Signed-off-by: Dan McGee <dan@archlinux.org>

* Attempt to fix up some of the brokenness around failed package loadsDan McGee2011-08-08
| | | | | | | | | | | | | | | This is a bit of a mess, due to the fact that we have a progress meter running. It is also ironic that we are in the midst of a method named "commit" when we haven't done a damn thing yet, and can still fail hard if either a checksum or signature is invalid or unrecognized. Adapt the former test_md5sum method to be invoked for any of the various failure types, which at least gives the user some indication of what packages are failing. A second patch will be needed to actually show worthwhile error codes, but this is going to involve modifying the actual data passed with the callback. Signed-off-by: Dan McGee <dan@archlinux.org>

* _alpm_access(): don't call gettext() in debug level loggersDan McGee2011-08-08

* | Store a package info level flag if we fail to load dataDan McGee2011-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | Check return value of rename() callsDan McGee2011-08-08
| | | | | | | | | | | | | | | | | | We did a good job checking this in add.c, but not necessarily anywhere else. Fix this up by adding checks into dload.c, remove.c, and conf.c in the frontend. Also add loggers where appropriate and make the message syntax more consistent. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Don't trim whitespace when reading database entriesDan McGee2011-08-02
| | | | | | | | | | | | | | | | | | | | | | 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.

* | Revamp signing checksDan McGee2011-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | This ensures we are actually making correct use of the information gpgme is returning to us. Marginal being allowed was obvious before, but Unknown should deal with trust level, and not the presence or lack thereof of a public key to validate the signature with. Return status and validity information in two separate values so check methods and the frontend can use them independently. For now, we treat expired keys as valid, while expired signatures are invalid. 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.

| | | | | | | | | | | | | | | | As noted by Allan, we failed pretty hard if gpgme was compiled out. With these changes, only sign001.py fails. This can/will be fixed later once we beef up the test suite with more signing tests anyway. Signed-off-by: Dan McGee <dan@archlinux.org>

* | Handle removal of empty directories properlyDan McGee2011-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This addresses FS#25141. We shouldn't remove every empty directory we come across during the removal process unless it is truly not known to any other package. This will prevent removal of essential directories such as '/var/lock/'. This is accomplished by first checking the empty/non-empty status of a directory, which was previously done implicitly by calling rmdir() and ignoring errors. We do this to avoid the next (new) check in most cases, which is to look at all local packages to see if the to-be-removed directory is present in another packages' filelist. If we do not find it anywhere, then we remove it, else we keep the file around. The pactest has been updated to test more cases, as well as finding a flaw in the original expected to fail case- we need separate DIR and FILE based EXIST rules.

* | Make alpm_db_set_pkgreason() arguments more saneDan McGee2011-07-14
| | | | | | | | | | | | | | | | | | This can only ever operate on the local database, and a local package at that. Change the function signature to take a handle and package object, add the relevant asserts, and ensure the frontend can detect the package not found condition when finding packages to pass to this method.

* | Allow fileconflict if unowned file moving into backup arrayDan McGee2011-07-14
| | | | | | | | | | | | | | | | | | | | | | The bulk of this commit is adding new tests to ensure the new behavior works without disrupting old behavior. This is a relatively sane maneuver when a package adds a conf file (e.g. '/etc/mercurial/hgrc') that was not previously in the package, but it is placed in the backup array. In essence, we can treat the existing file as having always been a part of the package and do our normal compare/install as pacnew logic checks. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Unify package removal codeDan McGee2011-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This code duplication has always been a rather clumsy casuality of fixing some past upgrade issues. Unify the removal code across upgrade and remove operations into a new _alpm_remove_single_package() method wihch makes it very clear how we handle upgrade and remove differently, via several conditionals on newpkg. This commit highlights interesting behavior such as the fact that the implicit removal in every package upgrade never gets transaction events or progress callbacks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This means creating a new struct which can pass more descriptive data from the back end sync functions to the downloader. In particular, we're interested in the download size read from the sync DB. When the remote server reports a size larger than this (via a content-length header), abort the transfer. In cases where the size is unknown, we set a hard upper limit of: * 25MiB for a sync DB * 16KiB for a signature For reference, 25MiB is more than twice the size of all of the current binary repos (with files) combined, and 16KiB is a truly gargantuan signature.

| * | dload: handle irregular URLsDave Reisner2011-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | URLs might end with a slash and follow redirects, or could be a generated by a script such as /getpkg.php?id=12345. In both cases, we may have a better filename that we can write to, taken from either content-disposition header, or the effective URL. Specific to the first case, we write to a temporary file of the format 'alpmtmp.XXXXXX', where XXXXXX is randomized by mkstemp(3). Since this is a randomly generated file, we cannot support resuming and the file is unlinked in the event of an interrupt. We also run into the possibility of changing out the filename from under alpm on a -U operation, so callers of _alpm_download can optionally pass a pointer to a *char to be filled in by curl_download_internal with the actual filename we wrote to. Any sync operation will pass a NULL pointer here, as we rely on specific names for packages from a mirror. Fixes FS#22645. Signed-off-by: Dave Reisner <d@falconindy.com>

* | | Remove most usages of strncmp()Dan McGee2011-07-05
|/ / | | | | | | | | | | | | | | | | | | | | | | The supposed safety blanket of this function is better handled by explicit length checking and usages of strlen() on known NULL-terminated strings rather than hoping things fit in a buffer. We also have no need to fully fill a PATH_MAX length variable with NULLs every time as long as a single terminating byte is there. Remove usages of it by using strcpy() or memcpy() as appropriate, after doing length checks via strlen(). Signed-off-by: Dan McGee <dan@archlinux.org>
* | Simplify alpm_list_previousAllan McRae2011-07-05
| | | | | | | | | | | | | | | | | | | | We can readily detect the first node in a list by checking if node->prev->next is NULL.

* | Allow invalid sync DBs to be returned by the libraryDan McGee2011-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | They are placeholders, but important for things like trying to re-sync a database missing a signature. By using the alpm_db_validity() method at the right time, a client can take the appropriate action with these invalid databases as necessary. In pacman's case, we disallow just about anything that involves looking at a sync database outside of an '-Sy' operation (although we do check the validity immediately after). A few operations are still permitted- '-Q' ops that don't touch sync databases as well as '-R'. Signed-off-by: Dan McGee <dan@archlinux.org>

Example output: Signatures : Valid signature from "Dan McGee <dpmcgee@gmail.com>" Unknown signature from "<Key Unknown>" Invalid signature from "Dan McGee <dpmcgee@gmail.com>" Also add a backend alpm_sigresult_cleanup() function since memory allocation took place on this object, and we need some way of freeing it.

* | Correctly check the GPG error codesDan McGee2011-07-05
| | | | | | | | | | | | | | | | | | | | The error code is in fact a bitmask value of an error code and an error source, so use the proper function to get only the relevant bits.

* | signing: move to new signing verification and return schemeDan McGee2011-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This gives us more granularity than the former Never/Optional/Always trifecta. The frontend still uses these values temporarily but that will be changed in a future patch. * Use 'siglevel' consistenly in method names, 'level' as variable name * The level becomes an enum bitmask value for flexibility * Signature check methods now return a array of status codes rather than a simple integer success/failure value. This allows callers to determine whether things such as an unknown signature are valid. * Specific signature error codes mostly disappear in favor of the above returned status code; pm_errno is now set only to PKG_INVALID_SIG or DB_INVALID_SIG as appropriate.
