DESCRIPTION
any of the directories on $GIT_ALTERNATE_OBJECT_DIRECTORIES)
enables git to read from such an archive.
+In a packed archive, an object is either stored as a compressed
+whole, or as a difference from some other object. The latter is
+often called a delta.
+
OPTIONS
-------
<base-name> to determine the name of the created file.
When this option is used, the two files are written in
<base-name>-<SHA1>.{pack,idx} files. <SHA1> is a hash
- of object names (currently in random order so it does
- not have any useful meaning) to make the resulting
- filename reasonably unique, and written to the standard
+ of the sorted object names to make the resulting filename
+ based on the pack content, and written to the standard
output of the command.
--stdout::
Write the pack contents (what would have been written to
.pack file) out to the standard output.
---window and --depth::
- These two options affects how the objects contained in
+--revs::
+ Read the revision arguments from the standard input, instead of
+ individual object names. The revision arguments are processed
+ the same way as gitlink:git-rev-list[1] with `--objects` flag
+ uses its `commit` arguments to build the list of objects it
+ outputs. The objects on the resulting list are packed.
+
+--unpacked::
+ This implies `--revs`. When processing the list of
+ revision arguments read from the standard input, limit
+ the objects packed to those that are not already packed.
+
+--all::
+ This implies `--revs`. In addition to the list of
+ revision arguments read from the standard input, pretend
+ as if all refs under `$GIT_DIR/refs` are specified to be
+ included.
+
+--window=[N], --depth=[N]::
+ These two options affect how the objects contained in
the pack are stored using delta compression. The
objects are first internally sorted by type, size and
optionally names and compared against the other objects
it too deep affects the performance on the unpacker
side, because delta data needs to be applied that many
times to get to the necessary object.
+ The default value for both --window and --depth is 10.
--incremental::
This flag causes an object already in a pack ignored
Only create a packed archive if it would contain at
least one object.
+--progress::
+ Progress status is reported on the standard error stream
+ by default when it is attached to a terminal, unless -q
+ is specified. This flag forces progress status even if
+ the standard error stream is not directed to a terminal.
+
+--all-progress::
+ When --stdout is specified then progress report is
+ displayed during the object count and deltification phases
+ but inhibited during the write-out phase. The reason is
+ that in some cases the output stream is directly linked
+ to another command which may wish to display progress
+ status of its own as it processes incoming pack data.
+ This flag is like --progress except that it forces progress
+ report for the write-out phase as well even if --stdout is
+ used.
+
+-q::
+ This flag makes the command not to report its progress
+ on the standard error stream.
+
+--no-reuse-delta::
+ When creating a packed archive in a repository that
+ has existing packs, the command reuses existing deltas.
+ This sometimes results in a slightly suboptimal pack.
+ This flag tells the command not to reuse existing deltas
+ but compute them from scratch.
+
+--delta-base-offset::
+ A packed archive can express base object of a delta as
+ either 20-byte object name or as an offset in the
+ stream, but older version of git does not understand the
+ latter. By default, git-pack-objects only uses the
+ former format for better compatibility. This option
+ allows the command to use the latter format for
+ compactness. Depending on the average delta chain
+ length, this option typically shrinks the resulting
+ packfile by 3-5 per-cent.
