* Represent bitfields as ints, not enumsIvy Foster2016-10-22
| | | | | | | | | | Many bitfield variables are declared to be enums, because they are generated using bitwise operations on enums such. However, their actual values aren't necessary members of their parent enum, so declaring them 'int' is more accurate.

* Add ALPM_ERR_OK to _alpm_errno_tIvy Foster2016-10-22
| | | | | | | | | | This allows functions which return an _alpm_errno_t to always return a genuine _alpm_errno_t for consistency, even in cases where there are no errors. Since ALPM_ERR_OK = 0, their callers can still simply check 'err = some_fn(); if (!err) { ... }'. Signed-off-by: Ivy Foster <ivy.foster@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org>

* make alpm_unlock and trans_interrupt async safeAndrew Gregory2016-02-23
| | | | | | | | | | RET_ERR calls _alpm_log which includes calls that are not safe for use in asynchronous signal handlers (see signal(7)). Replace it in functions called from our signal handlers with a new macro RET_ERR_ASYNC_SAFE which is identical except that it lacks the call to _alpm_log.

* Remove ts and sw from vim modeline when noet is setFlorian Pritz2014-01-28
| | | | | | | | | | | | Forcing vim users to view files with a tabstop of 2 seems really unnecessary when noet is set. I find it much easier to read code with ts=4 and I dislike having to override the modeline by hand.

* Fix build warnings with --disable-nlsAllan McRae2014-01-06
| | | | | | | | The gettext functions return a "char *", so do the same for the defines in the case where gettext is unavailable. This prevents a number of warnings about const being dropped. Signed-off-by: Allan McRae <allan@archlinux.org>
* do not check error from close(2)Dave Reisner2013-07-05
| | | | | | | | | | | | | | | On operating systems we support, the behavior is always such that the kernel will do the right thing as far as invalidating the file descriptor, regardless of the eventual return value. Therefore, potentially looping and calling close multiple times is wrong. At best, we call close again on an invalid FD and throw a spurious EBADF error. At worst, we might close an FD which doesn't belong to us when a multi-threaded application opens its own file descriptor between iterations of the loop.

* Split common utility functions for libalpm and pacmanAllan McRae2013-01-04
| | | | | | | | | | | | There is duplicated code in the util.c files in the libalpm and pacman source code. Split this into a separate file so that it can be shared via a symlink. This prevents code divergence between the two code bases. Also, move mbasename and mdirname from pacman/util.c into util-common.c in preparation for the following patch that uses them to add an extension to pacsave files.

* Convert ALLOC_FAIL macro into a functionDan McGee2012-04-29
| | | | | | | | | | | | | This path is rarely (read: never) taken in any normal run of the code, so injecting the fprintf() call everywhere with the macro is a bit overkill. Instead, add a lightweight _alpm_alloc_fail() function that gets called instead. This does have a reasonable effect on the size of the generated code; most places using the macros provided by util.c have their code size reduced. Signed-off-by: Dan McGee <dan@archlinux.org>
* Various tweaks to support building with excessive GCC warning flagsDan McGee2012-04-08
| | | | | | | | | This fixes a bunch of small issues in order to enable a clean successful build with a crazy number of GCC warning flags. A lot of these changes are covered by -Wshadow, -Wformat-security, and -Wstrict-overflow=5. Signed-off-by: Dan McGee <dan@archlinux.org>

* Remove rmrf implementation from backendDan McGee2012-01-23
| | | | | | | | | This moves the code for removal of local database entries right into be_local.c, which was the last user of the rmrf() function we had in our utility source file. We can simplify the implementation and make it non-recursive as we know the structure of the local database entries. Signed-off-by: Dan McGee <dan@archlinux.org>
* Remove strtrim function from backendDan McGee2011-12-23

* include config.h via MakefilesDave Reisner2011-12-21
| | | | | | | | | | | | | | | Ensures that config.h is always ordered correctly (first) in the includes. Also means that new source files get this for free without having to remember to add it. We opt for -imacros over -include as its more portable, and the added constraint by -imacros doesn't bother us for config.h. This also touches the HACKING file to remove the explicit mention of config.h as part of the includes.

* Add helper method for creating and opening archive objectDan McGee2011-11-16
| | | | | | | | | | | | | This moves the common setup code of about 5 different callers into one method. Error messages will now be common and shared in all places; several paths did not have any messages at all before. In addition, we now pick an ideal block size for the archive read based off the larger value of our default buffer size or the st.st_blksize field. For a filesystem such as NFS, this is often much larger than the default 8192- values such as 32768 and 131072 are common. Signed-off-by: Dan McGee <dan@archlinux.org>
* add support for back end fnmatch'd optionsDave Reisner2011-11-13
| | | | | | | | | | | | | This is work originally provided by Sascha Kruse on FS#20360 with only minor adjustments to the implementation. It's been expanded to cover: NoUpgrade, NoExtract, IgnorePkg, IgnoreGroup. Adds tests ignore008, sync139, sync502, and sync503. Also satisfies FS#18988.

| * Introduce ALPM_BUFFER_SIZE constantDan McGee2011-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This takes the place of three previously used constants: ARCHIVE_DEFAULT_BYTES_PER_BLOCK, BUFFER_SIZE, and CPBUFSIZE. In libarchive 3.0, the first constant will be no more, so we can ensure we are forward-compatible by removing our usage of it now. The rest are unified for consistency. By default, we will use the value of BUFSIZ provided by <stdio.h>, which is 8192 on Linux. If that is undefined, a default value is provided. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Convert MALLOC to actually call malloc()Dan McGee2011-10-12
| | | | | | | | | | | | | | | | | | | | If you need zero-filled allocations, call CALLOC() instead. This was from the original definition of these macros in commit cc754bc6e3be0f3; hopefully our code is in the shape it needs to be to switch this behavior. Signed-off-by: Dan McGee <dan@archlinux.org>
* | Introduce alpm_time_t typeDan McGee2011-10-12
|/ | | | | | | | | | This will always be a 64-bit signed integer rather than the variable length time_t type. Dates beyond 2038 should be fully supported in the library; the frontend still lags behind because 32-bit platforms provide no localtime64() or equivalent function to convert from an epoch value to a broken down time structure.

* Parse > 2GiB file sizes correctlyDan McGee2011-08-29
| | | | | | | | | | | | | | | | | | | | | | We were using atol(), which on 32 bit, cannot handle values greater than 2GiB, which is fail. Switch to a strtoull() wrapper function tailored toward parsing off_t values. This allows parsing of very large positive integer values. off_t is a signed type, but in our usages, we never parse or have a need for negative values, so the function will return -1 on error.

* 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.

* 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 sync DB reading a bit more flexibleDan McGee2011-06-24
| | | | | | | | | | | We can reorganize things a bit to not require reading a directory-only entry first (or at all). This was noticed while working on some pactest improvements, but should be a good step forward anyway. Also make _alpm_splitname() a bit more generic in where it stores the data it parses. Signed-off-by: Dan McGee <dan@archlinux.org>
* lib/util: call _alpm_log before setting handle->pm_errnoDave Reisner2011-06-20
| | | | | | | | | This is an unfortunate chain of events. RET_ERR and RET_ERR_VOID will eventually call CHECK_HANDLE, which resets the handle's pm_errno member. Dan probably had a reason for doing this, so we merely switch the order of operations in the RET_ERR macros to avoid stomping on our pm_errno. Signed-off-by: Dave Reisner <d@falconindy.com>
* Ensure handle is valid and pm_errno is reset when calling into APIDan McGee2011-06-14
| | | | | | | | | | | | | | | | | 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.
