2011-10-14Large performance improvement for check for owned directoriesDan McGee1-5/+11
We can take a large shortcut here that saves us a lot of time, especially when upgrading packages with lots of directories. Obviously iterating the full file list of every single package to determine if this directory was present in any other package can take quite some time on a system with many packages installed. We don't need to remove a directory at all if we are upgrading a package and the version we are moving to still had the directory. Also make a small optimization on the package comparsion- we really only care about equality here, not the result of the compare, so we can shortcut using our name_hash. What kind of benefit does this give us? Oh, only a reduction from 295.7 million to 1.4 million strcmp() calls (99.5% fewer) during a `pacman -S linux libreoffice-common` operation.

2011-09-30Revamp scriptlet path formation for scriptlets in local databaseDan McGee1-4/+6
Expose the current static get_pkgpath() function internally to the rest of the library as _alpm_local_db_pkgpath(). This allows use of this convenience function in add.c and remove.c when forming the path to the scriptlet location. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-30Refactor _alpm_runscriptlet()Dan McGee1-2/+2
Add an is_archive parameter to reduce the amount of black magic going on. Rework to use fewer PATH_MAX sized local variables, and simplify some of the logic where appropriate in both this function and in the callers where duplicate calls can be replaced by some conditional parameter code. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-09-28Move pacsave path construction code off the stackDan McGee1-2/+6
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>
2011-09-19Be smarter about running ldconfig during removal transactionsDan McGee1-6/+8
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>
2011-09-19Search for non-prefixed paths in skip_remove listDan McGee1-3/+3
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>
2011-09-02Former transaction callback rename refactorDan McGee1-7/+7
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 McGee1-7/+7
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>
2011-08-19Be more robust when copying package dataDan McGee1-9/+26
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>
2011-08-18Remove use of no-op accessor functions in libraryDan McGee1-3/+3
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>

Signed-off-by: Dan McGee <dan@archlinux.org>
2011-08-08Check return value of rename() callsDan McGee1-6/+18
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>
2011-07-21Convert package filelists to an array instead of linked listDan McGee1-10/+15
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.

2011-07-18Handle removal of empty directories properlyDan McGee1-6/+39
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.

2011-07-14Allow fileconflict if unowned file moving into backup arrayDan McGee1-1/+1
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>
2011-07-06Unify package removal codeDan McGee1-106/+96
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. Signed-off-by: Dan McGee <dan@archlinux.org>
2011-07-05Simplify alpm_list_previousAllan McRae1-2/+2
We can readily detect the first node in a list by checking if node->prev->next is NULL. So there is no need to pass the head of the list to this function and its prototype now looks like all the other item accessors.

2011-07-03Move alpm filelists to a struct objectDan McGee1-14/+15
This allows us to capture size and mode data when building filelists from package files. Future patches will take advantage of this newly available information, and frontends can use it as well. Signed-off-by: Dan McGee <dan@archlinux.org>

2011-06-14Ensure handle is valid and pm_errno is reset when calling into APIDan McGee1-1/+1
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.
