Colby Ranger 38b503601a Merge "Update DfsGarbageCollector to not read back a pack index." 2013-01-18 19:38:08 -05:00
Colby Ranger 7c58f6282a Update DfsGarbageCollector to not read back a pack index.
Previously, the Dfs GC excluded objects from packs by passing a
previously written index to the PackWriter. Reading back a file on
Dfs is slow. Instead, allow the PackWriter to expose the objects
included in a pack and forward that to invocations of excludeObjects() .

Tomasz Zarna 6a8da4c134 Add additional FastForwardMode enums for different config contexts
FastForwardMode is represented by different strings depending on context 
it is set or get from. E.g. FastForwardMode.FF_ONLY for
branch.<name>.mergeoptions is "--ff-only" but for merge.ff it is "only".

Colby Ranger 698705c754 Rename PackConstants to PackExt, a typed pack file extension.
PackConstants previously contained string values for the pack and pack
index extension. Change PackConstant to be PackExt, a typed wrapper
around the string pack file extension.

Robin Rosenberg 5213f6e2e8 Define a tree filter for user-visible changes between two indexes
The primary purpose of the filter is to detect an index change that
could possibly lead to a change in what files are visible in the staging
view and decorations. Besides what TreeFilter.ANY_DIFF does for trees in
general, this filter also looks at the assume-valid (CE_VALID) flag to
see whether changes should be ignored or not.

Colby Ranger 3f0176aea6 Remove getReverseIndexSize() from DfsPackDescription.
The method is used in only one location (DfsPackFile). Furthermore,
PackIndex already does an explicit computation of the size in
DfsPackFile. Simplify the DfsPackDescription by removing the method
and do the calculation similar to PackIndex.

Colby Ranger 510a605546 Use file extension with DfsPackDescription get/set file size.
Previously the size getters and setters had explicit methods for index
and pack. Update the api to be based on the file extension. This will
make it possible to support other extensions in the future, such as
the forthcoming bitmap extensions.

Roberto Tyley 5dcc8693d7 Fix concurrent creation of fan-out object directories
If multiple threads attempted to insert loose objects into the same new
fan-out directory, the creation of that directory was subject to a race
condition that could lead to an unnecessary IOException being thrown -
because an inserter could not 'create' a directory that had just been
generated by a different thread. All we require is that the directory
does indeed *exist*, so not being able to _create_ it is not actually a
fatal problem. Setting 'skipExisting' to 'true' on the call to mkdir()
fixes the issue.

I found this issue as a real world occurrence while working on The BFG
Repo Cleaner (https://github.com/rtyley/bfg-repo-cleaner), a tool which
concurrently performs a lot of object creation.

In order to demonstrate the problem here I've added a small test case
which reliably reproduces the issue on the few different hardware
systems I've tried. The error thrown when the race-condition arises is
this:

java.io.IOException: Creating directory /home/roberto/repo.git/objects/e6 failed

Colby Ranger 82ecfb3e31 Remove packIndex field from FileObjDatabase openPack method.
Previously, the FileObjDatabase required both the pack file path and
index file path to be passed to openPack().  A future change to add
a bitmap index will add a .bitmap file parallel to the pack file
(similar to the .idx file). Update the PackFile to support
automatically loading pack index extensions based on the pack file
path.

Colby Ranger 5d3c2b3def Update DfsObjDatabase API to open/write by pack extension.
Previously, the DfsObjDatabase had a hardcoded getPackFile() and

A future change to add a bitmap index will need to be stored in a
parallel .bitmap file. Update the DfsObjDatabase to support opening and
writing of files for any pack extension.

Robin Rosenberg 9e36b173a5 pgm: Attempt to detect a broken pipe and exit silently
When piping output to another program, the other pipe may exit
before we are done. An example is "jgit log|head". The result is
that errno get set to EPIPE. Unfortunately Java does not have
specific exception for this so we have to look at the exception
message and hope that the number of variants are small.

The detection here seem to work on Windows, Linux and OS X and it
seems the message is usually not localized.

Matthias Sohn 00739e6f70 Do not install unnecessary Orbit bundles
The org.eclipse.jgit.orbit.feature introduced recently in order to
install 3rd party Orbit dependencies is a too coarse grained approach
and has the effect to install some dependencies only needed for
org.eclipse.jgit.pgm when installing org.eclipse.jgit.feature.

Hence include the required 3rd party bundles into the respective jgit
features directly in order to avoid this problem.

Shawn Pearce 0b6387fe7c Revert "Stop PathFilter after walking all matching paths"
This reverts commit 75eb6a147f.
Applications that want a PathFilter to abort the walk early should be
using PathFilterGroup. When a PathFilterGroup is created with exactly
one path its implementation is the same that 75eb6 tried to perform,
but has been long documented as having the behavior of breaking a
higher level OR filter graph node.

Robin Rosenberg 315f1cfa5c Update the revert command and things relating to revert
Cherry-pick has been fixed, but even though revert does
basically the same thing, the fixes were not carried over here.

- Recognize the revert-states, analogous to the cherry picking states
- Make reset handle a revert-in-progress
- Update REVERT_HEAD and MERGE_MSG when revert fails due to conflicts
- Clear revert state on commit and reset
- Format the message similarily to how cherry-pick does. This is
  not exactly how C Git does it.

The interface is still not the same as for cherry-picking.

Dave Borowitz 75eb6a147f Stop PathFilter after walking all matching paths
After the current path of the TreeWalk is no longer a prefix of the
PathFilter's path, there can be no more matching entries, but TreeWalk
will happily keep walking the rest of a (potentially very large and
recursive) tree unless StopWalkException is thrown. So, throw
StopWalkException from PathFilter.include() at the earliest
opportunity.

Colby Ranger 51beee5568 Enforce max memory for DeltaWindow.
Previously, memory limits were enforced at the start of each iteration
of the delta search, based on objects that were currently loaded in
memory. However, new objects added to the window may be expanded in a
future iteration of the search and thus were not accounted for correctly
at the start of the search. To fix this, memory limits are now enforced
before each object is loaded.
