2011-08-19Rework finding a writable cache directoryDan McGee
This is a refactor and refresh of the code used to find where we should download packages. * Incorporate suggestions from FS#25435 to use TMPDIR from the environment if set, otherwise fall back to /tmp as before. * Make the writability tests a bit more in depth. We now do a three part check consisting of: - S_ISDIR(): is this even a directory - access(W_OK): is this directory writable by the current user. Unfortunately for root, this almost always returns that it is, but in the case of a RO mount or NFS share inaccessible to root, this check will exclude the directory. - mode & (any write bit): is there a writable bit set on this directory. This makes it possible to enforce a read-only cache directory by setting permissions to 0555, for example. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-19Be more robust when copying package dataDan McGee
This changes the signature of _alpm_pkg_dup() to return an integer error code and provide the new package in a passed pointer argument. All callers are now more robust with checking the return value of this function to ensure a fatal error did not occur. We allow load failures to proceed as otherwise we have a chicken and egg problem- if a 'desc' local database entry is missing, the best way of restoring said file is `pacman -Sf --dbonly packagename`. This patch fixes a segfault that was occurring in this case. Fixes the segfault reported in FS#25667. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-19lib/dload: unlink on response code >=400Dave Reisner

2011-08-19dload: add 'unlink_on_fail' to payload structDave Reisner
Let callers of _alpm_download state whether we should delete on fail, rather than inferring it from context. We still override this decision and always unlink when a temp file is used. Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-19makepkg: quote re-evaluation of simple varsDave Reisner
This is a safety measure to prevent simple code injection. $ i="foo bar" $ eval i="$i" bash: bar: command not found $ eval i=\"$i\" $ echo "|$i|" |foo bar| Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-18makepkg: deal with variable substitution when checking sanityAllan McRae
If any of pkgver, pkgrel or epoch contained a variable substitution, then it needed to be evaluated before checking its value conformed to the rules. [Dan: add quotes around RHS] Signed-off-by: Allan McRae <allan@archlinux.org> Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18doc/PKGBUILD: update regarding versioned package fieldsDan McGee
Add the info that versioned replaces are now supported, as well as beefing up some of the other places touching on versioned fields. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Convert resolvedep() to use _alpm_depcmp_literal()Dan McGee
The whole first loop is trying to check literals only, so teach it to do so. Also, reorder operations to make more sense by putting the strcmp() first in the literal loop, and using a very cheap name_hash check first in the second loop. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Fix replacement of provider issueDan McGee
When we switched to using alpm_depcmp() in resolving replacments, we had some interesting behavior with regard to providers and packages not found in repositories. Teach the replacement resolving code to not look at provisions at all to be slightly more sane. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Add an _alpm_depcmp_literal() functionDan McGee
This omits the finding of matching provisions and only checks the package itself against the provided dep. Signed-off-by: Dan McGee <dan@archlinux.org>

Another function call that can be replaced by a single pointer dereference. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-18Remove use of no-op accessor functions in libraryDan McGee
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 McGee
* 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.

2011-08-17lib/dload: refactor deletion on failureDave Reisner
This moves all the delete-on-fail logic to under cleanup label. This also implies should_unlink when a payload is received that doesn't allow resuming.

2011-08-17Avoid stat() on NULL path in curl_download_internal()Lukas Fleischer
stat()'s behaviour is undefined if the first argument is NULL and might be prone to segfault. Add an additional check to skip the stat() invocation if no destfile is used. Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de> Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-16configure.ac: add checks for more types, functions and headersAllan McRae
This covers most types, functions and headers that we use in the code base. Currently we do not use any of these checks, but it is useful to have the configure output when looking at build issues on other peoples systems.

2011-08-16dload: zero out pm_errno in curl_download_internalDave Reisner
This reverts some hacky behavior from 5fc3ec and resets the handle's pm_errno where it should be reset -- prior to each download. This prevents a transaction with a download from being aborted when a package is successfully grabbed from a secondary server.

2011-08-16doc/PKGBUILD: fix Asciidoc formatting issuesDan McGee

2011-08-15repo-add: reorganize output messages for clarityDan McGee
The use of warning once we had already started adding a package was confusing as it broke the standard indent pattern. It was especially bad if adding multiple packages as it wasn't clear what sub-messages applied to which package being added. This should be an output change only from: ==> Adding package '/tmp/sync/netcfg-2.6.7-1-any.pkg.tar.xz' -> Computing checksums... -> Adding package signature... ==> WARNING: An entry for 'netcfg-2.6.7-1' already existed -> Removing existing entry 'netcfg-2.6.7-1'... -> Creating 'desc' db entry... -> Creating 'depends' db entry... to: ==> Adding package '/tmp/sync/netcfg-2.6.7-1-any.pkg.tar.xz' ==> WARNING: An entry for 'netcfg-2.6.7-1' already existed -> Computing checksums... -> Adding package signature... -> Removing existing entry 'netcfg-2.6.7-1'... -> Creating 'desc' db entry... -> Creating 'depends' db entry... Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-15Only check necessary signatures and checksumsDan McGee
The precedence goes as follows: signature > sha256sum > md5sum Add some logic and helper methods to check what we have available when loading a package, and then only check what is necessary to verify the package. This should speed up sync database verifies as we no longer will be doing both a checksum and a signature validation. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-15lib/sync: ignore download errors for as long as possibleDave Reisner
Previously, the behavior was such that if a sync operation required packages from multiple repos, a download error in the first repo would cause a hard repo, ignoring the remainder of the repositories. Change this behavior so that we do a better job of fetching as many packages as possible before aborting the transaction. There's a little bit of refactoring mixed in here to get rid of some useless variables. Since we now depend heavily on the value of handle->pm_errno being accurate the determine the function's return value, we clear it when the transaction state is set. Fixes FS#25532.

2011-08-15Further fixes to replacement iterationDan McGee
A partial fix for this was in commit 7de92cb22, but this should fix the remaining cases. There are still several issues dealing with "provision as replacement" selection however. Addresses FS#25538 and FS#25527. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-08-15Parse conflicts/provides/replaces at database load timeDan McGee
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.

2011-08-15decode_signature: guess signature data length for efficiencyDan McGee
We may end up allocating 1 or 2 extra bytes this way, but it is worth it to simplify the method and not have to call base64_decode() a second time. Use the hueristic that base64 encoding produces 3 bytes of decoded data for every 4 bytes of encoded data. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-15Remove checksum access indirectionDan McGee
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>
2011-08-15lib/sync: reset flag after rejecting a replaceDave Reisner
