On some operating systems, read() of a directory fd may actually succeed and
return garbage resembling on-disk contents. As a result, dotgit may return
successful from readReferenceFile() when it should in-fact not.
This fixes readReferenceFile() on FreeBSD.

Specifically, the problem demonstrated is that on some OS (e.g. FreeBSD),
read() on a directory will succeed. The current implementation will accept
that and return incorrect results, rather than rejecting the directory.

When we assign a value to err, make sure to also check for it being nil
afterwards. If those were intentionally unchecked, we should remove the
assignment in the first place. Those checks certainly never harm, but please
review thoroughly and let me know.

filesystem: ObjectStorage, MaxOpenDescriptors option
|
| |
| |
| |
| |
| |
| |
| |
| | |
The MaxOpenDescriptors option provides a middle ground solution between keeping
all packfiles open (as offered by the KeepDescriptors option) and keeping none
open.

Large performance increase by buffering reads.
There were a few instances where binary.Read() would end up using reflection on
&plumbing.Hash, rather than treating it as a byte slice. This has now been
resolved.

If the cache is shared between several repositories getFromUnpacked can
erroneously return an object from other repository.
This decreases performance a little bit as there's an extra fs operation
when the object is in the cache but is correct when the cache is shared.

PackfileIter was not taking into account the option KeepDescriptors
and was always closing the file. This caused "file already closed"
errors when iterating packfiles in with KeepDescriptors active.

Using equals to compare files it uses diff to do so. This can
potentially consume lots of ram. Changed the comparison to use file
offsets. If the descriptor is reused the offset is maintained.

This option maintains packfile file descriptors opened after reading
objects from them. It improves performance as it does not have to be
opening packfiles each time an object is needed.
Also adds Close to EncodedObjectStorer to close all the files manualy.

Also adds Static configuration to Storage and DotGit. This option means
that the git repository is not expected to be modified while open and
enables some optimizations.
Each time a file is accessed the storer tries to open an object file for
the requested hash. When this is done for a lot of objects it is
expensive. With Static option a list of object files is generated the
first time an object is accessed and used to check if exists instead of
using system calls.
A similar optimization is done for packfiles.

Search for incoming object directory was done once each time objects
were accessed. This means a ReadDir of the objects path that is
expensive. Now incoming directory is searched the first time an object
is accessed and its name kept in DotGit to be reused.

After clone only resolved deltas were added to the cache. This caused
slowdowns in small repositories where most objects can be held in cache.
It also makes packfiles reuse delta cache from the store. Previously it
created a new delta cache each time a packfile object was created. This
also slowed down a bit accessing objects and had an impact on memory
consumption when bases are added to the cache.
