2021-12-14fix fetching of depdencies only packagesTimo Teräs4-16/+12
Remove the APK_REPOSITORY_CACHED bit from dependencies only packages (that is, installed_size == 0). For fetch, the problem is that apk_db_select_repo() would return the cache repository, but the package would not be there. Update also the locations needed to handle these packages correctly without the cached repository bit being set.
2021-11-12fetch: add --url option to print the download URLsTimo Teräs1-6/+14
2021-11-12db: purge temporary files without explicit modification checkTimo Teräs1-1/+2
When extraction failed, the user has had no opportunity to edit any files. Just clean up.
2021-10-25version: increase number of digits supported in version componentTimo Teräs1-3/+6
Report also version numbers as invalid if there's more than 18 digits. fixes #10774
2021-08-23tar: improve compatibilityTimo Teräs1-20/+30
- check magic field for 'ustar' on read - harden get_octal to report errors on non-octal characters (e.g. GNU base256 encoding), fixes #10757 - fix mtime and size octal fields to not have zero terminator
2021-08-23db: honor SOURCE_DATE_EPOCH for scriptdbTimo Teräs1-2/+0

2021-07-26db: fix installed db writing with long namesSamanta Navarro1-6/+11
Packages containing files with path names longer than 1024 characters cannot fit into the buffer which is used to write "installed" database. This leads to bbuf being APK_BLOB_NULL in apk_db_write_fdb because apk_blob_push_blob notices the condition and correctly handles it. The problem occurs when arguments to apk_ostream_write are manually calculated by pointer arithmetics. Since bbuf.ptr is NULL in such a case, bbuf.ptr - buf leads to a huge size value while buf still points into the stack. fixes #10751 [TT: minor edit to commit and abbreviating the commit message]

2021-07-23Disable progress bar on dumb terminals by defaultSören Tempel1-1/+6
The progress bar requires the terminal emulator to support ANSI escape sequences. Normally, TERM is set to dumb to indicate that the terminal emulator doesn't support any ANSI escape sequences. Attempting to use ANSI escape sequences on dumb terminals will lead to weird output. In order to make apk work by default, even on dumb terminals, this commit introduces an additional check which consults $TERM and disables the progress bar if it is set to "dumb". [TT: backported to 2.12]
2021-05-20solver: don't consider requirer count for preferenceTimo Teräs1-18/+0
The original intent was to choose packages to which there is most dependencies. However, since the code has evolved this is has been mostly obsolete. And in fact now interferes with the provides and provides priority mechanism. Remove this as obsolete. Fixes #10742
2021-04-11io_archive: add bounds limit for uname and gname tar header fieldsTimo Teräs3-10/+11

2021-04-11io: fix fd leak in error handling pathsTimo Teräs1-5/+20
apk_dir_foreach_file and apk_resolve_[ug]id needs to free the fd in case fdopen/fdopendir fails. Additionally this does not rely on fdopen to fail if openat() returned -1, making sure that we don't call any syscalls with invalid file handle.
2021-03-19database: do not chroot(".") unless actually necessaryAriadne Conill2-2/+14
If we use default root (/), then we do not have to chroot to run scripts. Use APK_NO_CHROOT flag for this scenario to avoid the chroot. This helps with using apk with bwrap and OSTree. Closes #10736. [TT: backported to 2.12-stable]
2021-03-19del: report correctly package's provides namesTimo Teräs1-9/+21
The code assumed that when package is in world, it would be there by it's primary name. The code is now updated to properly print the package names that are actually present in world. fixes #10718
2021-02-07db: fix control character check to use uint8_tTimo Teräs1-2/+2
fixes #10737
2021-02-07db: consider control characters in filename as maliciousTimo Teräs3-11/+25
Especially a newline can produce havoc in the database file as the filename is written there as-is. This hardenes the extraction to consider any control character as malicious. Additional hardening is added to database loading to better detect corrupt state and return proper error code about it. Reported-by: Luca Weiss <luca@z3ntu.xyz>
2021-02-07io: Handle really long linesOlliver Schinagl1-1/+1
While commit 18b0b45 (io: Handle long lines, Thu Jan 7 17:25:23 2021 +0100) did attempt to address this issue, the buffer really is still to small when dealing with big-big dependency lists. Lets make it sufficiently large for now, until the new APKINDEX format can support multi-line dependencies, making this not needed any more. [TT: Originally the buffer size was conservative to run on resource constrained embedded platforms. But since the available memory on those has also increased much, the adjustment to 128kB makes sense also to increase performance a little bit. Removing also the iolimit test.] Signed-off-by: Olliver Schinagl <oliver@schinagl.nl>
2021-02-07gunzip: fix false end-of-file condition in rare circumstancesTimo Teräs1-1/+1
It turns out inflate() can output zero bytes, even if it consumed data. This had the unfortunate side effect of returning zero bytes (end-of-file) condition before calling the boundary callbacks. This fixes the logic to not return zero reads on gzip boundary. In practice this fixes the seldom seen issues of apk reporting bad signature (when it was correct).
2021-01-14database.c: Fixed package DESCRIPTION parsingthibault.ferrante1-0/+1
Regression introduced by 0fb0d30 which makes parsing a description a critical failure. [TT: Minor stylistic change. Fix also missing final line change from the earlier commit]
2021-01-11io: Handle long linesthibault.ferrante1-1/+1
As an APKINDEX can become arbitrarely long due to dependencies and other parameters, increasing the buffer size make this less likely to happens. Closes #10731.

2020-10-06database: automatically create missing cache dirPaul Spooren1-0/+6
On some systems the `/var/` dir is mounted in a tmpfs which is reseted after each reboot. For that reason no post-install script can handle the creation of the cache dir at `/var/cache/apk`. Check on database opnening if the folder is available, if not create it. Fixes #10715 Signed-off-by: Paul Spooren <mail@aparcar.org>
2020-10-05db: make --repositories-file relative to host rootTimo Teräs1-1/+1
It used to be relative to the --root specified root, but that causes issues with relative command line filenames and is unintuitive. Update documentation accordingly. Fixes #10702.

2020-08-24enforce options definitions to bind the enum and the descriptorTimo Teräs15-288/+175
This uses some macro trickery to make sure that there's one-to-one mapping with the option index enum and the descriptor. The down side is that enum's are generated via #define's and editors might not pick them up for auto completion, but the benefits are more: it's no longer possible have mismatching enum value and descriptor index, and the amount of source code lines is less.

2020-05-19make the atom functions not use global stateTimo Teräs24-179/+185
This greatly helps with memory management on applications that may want to daemonize and open/close database several times. Also the lifetime and "owner" of memory for all data is now explicitly bound to owning struct apk_database, which might be helpful when writing language bindings. As side effect, the interned "atoms" are unique only within what apk_database, so comparing packages from different apk_database may not work as expected. Fixes #10697

2020-05-06index: add argument --no-warningsFredrik Gustafsson1-1/+11
When creating an index apk warns if a dependency is missing a provider. However when using a multi-arch repository, it's not an error that a certain architecture is missing a dependency because that dependency could be in an other architecture. Since apk index doesn't know about this, add an argument to disable that warning. Maintainer note: rebased for new option handling, and minor stylistic adjustments.

2020-05-06rewrite option descriptors to be single stringTimo Teräs16-435/+563
This reduces the number of relocations on PIE binaries, and also reduces the executable size. Parsing of the options is slightly sped up as only the exact matching option group parser is called.
