* avoid blowing out the filecache list when using tmpdirDave Reisner2011-09-06
| | | | | | | | | | | | | | | | _alpm_filecache_setup() destroys the list of cachedirs when it finds no writeable directories in the config. This put us in an awkward situation where _alpm_filecache_find() would locate a downloaded file in a r/o cachedir, but then fail to install it after _alpm_filecache_setup() is called (with a NULL argument). Change this behavior to merely prepend the temporary directory to the list of available cachedirs. Dan exposed it in e07547ee4ed4, as now a package can be found in a directory we may not be able to actually store packages in.

* Former transaction callback rename refactorDan McGee2011-09-02
| | | | | | | | | | | | | 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>
* Move all callbacks up to the handle levelDan McGee2011-09-02
| | | | | | | | | 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.

* 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.

* strtrim: don't move empty stringDan McGee2011-08-25
| | | | | | | | | | There were many cases where the string coming in was a blank line, e.g. "\n\0", length 1. The trim routine starts by trimming leading spaces, thus trimming everything. We would then proceed to do a memmove of the NULL byte, which is completely worthless as we can just assign it instead. Signed-off-by: Dan McGee <dan@archlinux.org>
* Rework finding a writable cache directoryDan McGee2011-08-19
| | | | | | | | | | | | | | | | | | | | 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>

* 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>
* _alpm_access(): don't call gettext() in debug level loggersDan McGee2011-08-08
| | | | | | | | This is standard procedure elsewhere and cuts down on translations that won't be seen (and we don't want if we need English debug output anyway). 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.

* 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.

* Fix several -Wshadow warningsDan McGee2011-06-27
| | | | | | | | | | Only one of these looked like a real red flag, in find_requiredby(), but it doesn't hurt to fix several of them up anyway. Unfortunately, we can't turn this on universally due to things like the sync(), remove(), etc. builtins which we often use as variable names. Signed-off-by: Dan McGee <dan@archlinux.org>
* 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>
* archive_fgets(): ensure we return any trailing text with no newlineDan McGee2011-06-24
| | | | | | | | | | Discovered this when doing some pactest rewrite work to generate archives in memory only. If a sync database file or PKGINFO file is missing a newline on the final line, the text from that line gets tossed aside and never read into the package struct. This is pretty critical when that last line is a depend or something. Signed-off-by: Dan McGee <dan@archlinux.org>

* _alpm_lstat: only duplicate string if necessaryDan McGee2011-06-09
| | | | | | | | | The vast majority of the time we will just be passing the same string value on to the lstat() call. The only time we need to duplicate it is if the path ends in '/'. In one run using a profiler, only 400 of the 200,000 calls (0.2%) required the string to be copied first. Signed-off-by: Dan McGee <dan@archlinux.org>
* Add helper methods for setting directory optionsDan McGee2011-06-07

* Use standard errno codes in return from _alpm_archive_fgetsDan McGee2011-06-03
| | | | | | | | | | | | | This allows us to not require the context (e.g. handle) when calling this function. Also beef up the checks in the two callers of this function to bail if the last return code is not ARCHIVE_EOF, which is the expected value. This requires a change to one of the pactest return codes and the overall result of the test, but results in a much safer operating condition whereby invalid database entries will stop the operation.

| | | | | | | | | | | | | | | | | | | | This is a rather serious data corruption issue that luckily manifested itself today in a noticable way. A package in testing had replaces entries read in as ["%RE pkgname", "%RE"] which was clearly wrong.

A huge checkin, but if we just do it and let people adjust the pain will end soon enough.

| | | | | | | | | | According to FOPEN(3), using fclose on an fdopen'd file stream also closes the underlying file descriptor.
