libfstree: add an assertion that root is not NULL

2021-03-25T13:49:52+00:00

If the path argument is "", we assume that referes to root and set the *existing* target node to the root node and skip ahead across the tree search. This leaves "name" uninitialized, which makes coverity panic, because fs->root could be NULL, going down the wrong path. Obviously, this should never, *ever* happen and there is no reasonable recovery strategy if it suddenly does, so simply add an assertion. Signed-off-by: David Oberhollenzer

Fix fail branch in block processor fragment backend

2021-03-25T13:47:06+00:00

Only clean up the fragment if it hasn't been re-assigned to the fragment block. The NULL check is definitely wrong, because we no longer re-assign it as NULL. Signed-off-by: David Oberhollenzer

libfstree: Allow / as argument for "glob" and "dir" commands

2021-03-25T13:35:39+00:00

This allows putting globbed files & directories into the filesystem root, as well as explicitly setting attributes of the root directory from the file lisiting. Signed-off-by: David Oberhollenzer

Fix block processor queue accounting

2021-03-24T13:05:18+00:00

Dequeuing won't work if we have a backlog of 1 or 2 and the blocks are used for internal buffering. Take that into account, similar to the sync code. Also bump the minimum backlog to 3, just to make absolutely sure we cannot run into a dequeue loop trying to allocate a block. Signed-off-by: David Oberhollenzer

libfstree: implement directory scanning code for Windows

2021-03-24T08:59:07+00:00

It's rather simplistic and doesn't account for junction/reparse points, which is the closest thing Windows has to symlinks, hard links and mount points, but it's consistent with the unpacking code that assumes Windows only has files and directories. Using the 32 bit mingw toolchain, this seems to satisfy the unit tests on wine. Signed-off-by: David Oberhollenzer

block processor: Re-implement exact fragment matching

2021-03-23T10:39:52+00:00

In the hash-table equals callback, if the hash and size match, do an exact, byte-for-byte comparison of the fragment in question. The fragment can either be in a fragment block that is in-flight (for which we have the in-flight list), in the current, unfinished fragment block, or it can be on disk. In the later case, the fragment block is resolved through the fragment table and read back from disk into a scratch buffer and decompressed. After that, the fragment is checked for byte-for-byte equality with the one we resolved through the hash table. Signed-off-by: David Oberhollenzer
