2011-09-27_alpm_splitdep: use malloc instead of callocDan McGee
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>
2011-09-22Update Doxyfile and fix some documentation errors caught by DoxygenDan McGee
A few parameters were outdated or wrongly named, and a few things were explicitly linked that Doxygen wasn't able to resolve.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>
2011-09-20Remove all usages of alpm_list_getdata() from the libraryDan McGee
No need for the indirection; just access ->data instead. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-02Former transaction callback rename refactorDan McGee
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>
2011-09-02Move all callbacks up to the handle levelDan McGee
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>
2011-08-29Streamline alpm_splitdep() comparisonsDan McGee
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>
2011-08-28_alpm_splitdep(): don't pass bogus length value to strndupDan McGee
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>
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>
2011-08-18Convert 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>
2011-08-18Add 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>
2011-08-18Remove usages of alpm_list_next() in backendDan McGee
Another function call that can be replaced by a single pointer dereference. 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. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-11Add -S --recursive operationDan McGee
This closely matches what we had before for -R --recursive. Basically, when specifying a target (e.g., pacman), we can now recursively pull all dependencies, regardless of version specifiers and whether they are already satisfied in the local database. This could be used to update pacman on a system with an old glibc, for example, as both pacman and glibc would get pulled into the transaction. This is most useful with --needed to prevent needless reinstalls as described in the man page changes. The end goal of this change is to wire it into SyncFirst and have it be the default mode of operation there, but that belongs in a separate changeset. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee
We didn't do due diligence before and ensure prior pm_errno values weren't influencing what happened in further ALPM calls. I observed one case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that flag persisting the entire time we were calling library code. Add a new CHECK_HANDLE() macro that does two things: 1) ensures the handle variable passed to it is non-NULL and 2) clears any existing pm_errno flag set on the handle. This macro can replace many places we used the ASSERT(handle != NULL, ...) pattern before. Several other other places only need a simple 'set to zero' of the pm_errno field. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-14Add handle argument to _alpm_pkg_should_ignore()Dan McGee
This allows callers to retrieve it from wherever is convenient, which may or may not be on the package object itself. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-13Switch all logging to use handle directlyDan McGee
This is the last user of our global handle object. Once again the diff is large but the functional changes are not. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-13Move pm_errno onto the handleDan McGee
This involves some serious changes and a very messy diff, unfortunately. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-13Add handle argument to two more alpm methodsDan McGee
This takes care of alpm_checkdeps() and alpm_find_dbs_satisfier(). Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-09Require handle argument to all alpm_trans_*() methodsDan McGee
Begin enforcing the need to pass a handle. This allows us to remove one more extern handle declaration from the backend. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-07Add helper methods for setting directory optionsDan McGee
This keeps duplicate code to a minimum. This will come in more handy as we refactor some of these option setters away. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Push down extern handle variable to files that need itDan McGee
This will make the patching process less invasive as we start to remove this variable from all source files. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-06-03Remove ALPM_LOG_FUNC macroDan McGee
The usefulness of this is rather limited due to it not being compiled into production builds. When you do choose to see the output, it is often overwhelming and not helpful. The best bet is to use a debugger and/or well-placed fprintf() statements. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-04-20syntax: if/while statements should have no trailing spaceDan McGee

2011-03-25Ensure reported missing dependencies show correct version comparisonDan McGee
This addresses FS#23424. The -dd backend code was introduced in commit b6ec9019d77, and unfortunately the munged depend used for comparison did not carry through to the eventual display of this version. To fix this, we undo some of the depcmp_tolerant() business introduced, and instead make a new pmdepend_t object if necessary when the no dependency version flag is set. This results in the correct depend being copied to the missing depend passed onto the frontend. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-03-20Style change: return(x) --> return xDan McGee
This was discussed and more or less agreed upon on the mailing list. A huge checkin, but if we just do it and let people adjust the pain will end soon enough. Rebasing should be relatively straighforward for anyone that sees conflicts; just be sure you use the new return style if possible. The following semantic patch was used to do the change, along with some hand-massaging in order to preserve parenthesis where appropriate: The semantic match that finds this problem is as follows, although some hand-massaging was done in order to keep parenthesis where appropriate: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a; @@ - return(a); + return a; // </smpl> A macros_file was also provided with the following content: Additional steps taken, mainly for ASSERT() macros: $ sed -i -e 's#return(NULL)#return NULL#' lib/libalpm/*.c $ sed -i -e 's#return(-1)#return -1#' lib/libalpm/*.c Signed-off-by: Dan McGee <dan@archlinux.org>
