DESCRIPTION
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
Traditionally, tips of branches and tags (collectively known as
|
2012-08-06 20:36:47 +00:00
|
|
|
'refs') were stored one file per ref in a (sub)directory
|
|
|
|
|
under `$GIT_DIR/refs`
|
2006-11-06 08:28:52 +00:00
|
|
|
directory. While many branch tips tend to be updated often,
|
|
|
|
|
most tags and some branch tips are never updated. When a
|
|
|
|
|
repository has hundreds or thousands of tags, this
|
|
|
|
|
one-file-per-ref format both wastes storage and hurts
|
|
|
|
|
performance.
|
|
|
|
|
|
|
|
|
|
This command is used to solve the storage and performance
|
2012-08-06 20:36:47 +00:00
|
|
|
problem by storing the refs in a single file,
|
2006-11-06 08:28:52 +00:00
|
|
|
`$GIT_DIR/packed-refs`. When a ref is missing from the
|
2012-08-06 20:36:47 +00:00
|
|
|
traditional `$GIT_DIR/refs` directory hierarchy, it is looked
|
|
|
|
|
up in this
|
2006-11-06 08:28:52 +00:00
|
|
|
file and used if found.
|
|
|
|
|
|
2009-04-04 10:35:22 +00:00
|
|
|
Subsequent updates to branches always create new files under
|
2012-08-06 20:36:47 +00:00
|
|
|
`$GIT_DIR/refs` directory hierarchy.

|
|
A recommended practice to deal with a repository with too many
|
|
|
|
|
refs is to pack its refs with `--all --prune` once, and
|
docs: stop using asciidoc no-inline-literal
In asciidoc 7, backticks like `foo` produced a typographic
effect, but did not otherwise affect the syntax. In asciidoc
8, backticks introduce an "inline literal" inside which markup
is not interpreted. To keep compatibility with existing
documents, asciidoc 8 has a "no-inline-literal" attribute to
keep the old behavior. We enabled this so that the
documentation could be built on either version.
It has been several years now, and asciidoc 7 is no longer
in wide use. We can now decide whether or not we want
inline literals on their own merits, which are:
1. The source is much easier to read when the literal
contains punctuation. You can use `master~1` instead
of `master{tilde}1`.
2. They are less error-prone. Because of point (1), we
tend to make mistakes and forget the extra layer of
quoting.
This patch removes the no-inline-literal attribute from the
Makefile and converts every use of backticks in the
documentation to an inline literal (they must be cleaned up,
or the example above would literally show "{tilde}" in the
output).
Problematic sites were found by grepping for '`.*[{\\]' and
examined and fixed manually. The results were then verified
by comparing the output of "html2text" on the set of
generated html pages. Doing so revealed that in addition to
making the source more readable, this patch fixes several
formatting bugs:
- HTML rendering used the ellipsis character instead of
literal "..." in code examples (like "git log A...B")
- some code examples used the right-arrow character
instead of '->' because they failed to quote
- api-config.txt did not quote tilde, and the resulting
HTML contained a bogus snippet like:
<tt><sub></tt> foo <tt></sub>bar</tt>
which caused some parsers to choke and omit whole
sections of the page.
- git-commit.txt confused ``foo`` (backticks inside a
literal) with ``foo'' (matched double-quotes)
- mentions of `A U Thor <author@example.com>` used to
erroneously auto-generate a mailto footnote for
author@example.com
- the description of --word-diff=plain incorrectly showed
the output as "[-removed-] and {added}", not "{+added+}".
- using "prime" notation like:
commit `C` and its replacement `C'`
confused asciidoc into thinking that everything between
the first backtick and the final apostrophe were meant
to be inside matched quotes
- asciidoc got confused by the escaping of some of our
asterisks. In particular,
`credential.\*` and `credential.<url>.\*`
properly escaped the asterisk in the first case, but
literally passed through the backslash in the second
case.

|
occasionally run `git pack-refs --prune`. Tags are by
|
2007-01-26 06:51:49 +00:00
|
|
|
definition stationary and are not expected to change. Branch
|
|
|
|
|
heads will be packed with the initial `pack-refs --all`, but
|
|
|
|
|
only the currently active branch heads will become unpacked,
|
2009-04-04 10:35:22 +00:00
|
|
|
and the next `pack-refs` (without `--all`) will leave them
|
2007-01-26 06:51:49 +00:00
|
|
|
unpacked.

|
|
|
The command by default packs all tags and refs that are already
|
|
|
|
|
packed, and leaves other refs
|
2006-11-06 08:28:52 +00:00
|
|
|
alone. This is because branches are expected to be actively
|
|
|
|
|
developed and packing their tips does not help performance.
|
|
|
|
|
This option causes branch tips to be packed as well. Useful for
|
|
|
|
|
a repository with many branches of historical interests.

--no-prune::

|
|
|
|

|
|
|
The command usually removes loose refs under `$GIT_DIR/refs`
|
|
|
|
|
hierarchy after packing them. This option tells it not to.

BUGS
|
|
|
|
|
----
|
|
|
|
|
|
|
|
|
|
Older documentation written before the packed-refs mechanism was
|
|
|
|
|
introduced may still say things like ".git/refs/heads/<branch> file
|
|
|
|
|
exists" when it means "branch <branch> exists".
