+Git v1.7.7 Release Notes
+========================
+
+Updates since v1.7.6
+--------------------
+
+ * The scripting part of the codebase is getting prepared for i18n/l10n.
+
+ * Interix, Cygwin and Minix ports got updated.
+
+ * Various updates git-p4 (in contrib/) and "git fast-import".
+
+ * Gitweb learned to read from /etc/gitweb-common.conf when it exists,
+ before reading from gitweb_config.perl or from /etc/gitweb.conf
+ (this last one is read only when per-repository gitweb_config.perl
+ does not exist).
+
+ * Various codepaths that invoked zlib deflate/inflate assumed that these
+ functions can compress or uncompress more than 4GB data in one call on
+ platforms with 64-bit long, which has been corrected.
+
+ * Git now recognizes loose objects written by other implementations that
+ uses non-standard window size for zlib deflation (e.g. Agit running on
+ Android with 4kb window). We used to reject anything that was not
+ deflated with 32kb window.
+
+ * Interaction between the use of pager and coloring of the output has
+ been improved, especially when a command that is not built-in was
+ involved.
+
+ * "git am" learned to pass "--exclude=<path>" option through to underlying
+ "git apply".
+
+ * You can now feed many empty lines before feeding a mbox file to
+ "git am".
+
+ * "git archive" can be told to pass the output to gzip compression and
+ produce "archive.tar.gz".
+
+ * "git bisect" can be used in a bare repository (provided if the test
+ you perform per each iteration does not need a working tree, of
+ course).
+
+ * The length of abbreviated object names in "git branch -v" output
+ now honors core.abbrev configuration variable.
+
+ * "git check-attr" can take relative paths from the command line.
+
+ * "git check-attr" learned "--all" option to list the attributes for a
+ given path.
+
+ * "git checkout" (both the code to update the files upon checking out a
+ different branch, the code to checkout specific set of files) learned
+ to stream the data from object store when possible, without having to
+ read the entire contents of a file in memory first. An earlier round
+ of this code that is not in any released version had a large leak but
+ now it has been plugged.
+
+ * "git clone" can now take "--config key=value" option to set the
+ repository configuration options that affect the initial checkout.
+
+ * "git commit <paths>..." now lets you feed relative pathspecs that
+ refer outside your current subdirectory.
+
+ * "git diff --stat" learned --stat-count option to limit the output of
+ diffstat report.
+
+ * "git diff" learned "--histogram" option, to use a different diff
+ generation machinery stolen from jgit, which might give better
+ performance.
+
+ * "git fetch", "git push" and friends no longer show connection
+ errors for addresses that couldn't be connected when at least one
+ address succeeds (this is arguably a regression but a deliberate
+ one).
+
+ * "git grep" learned --break and --heading options, to let users mimic
+ output format of "ack".
+
+ * "git grep" learned "-W" option that shows wider context using the same
+ logic used by "git diff" to determine the hunk header.
+
+ * The "--decorate" option to "git log" and its family learned to
+ highlight grafted and replaced commits.
+
+ * "git rebase master topci" no longer spews usage hints after giving
+ "fatal: no such branch: topci" error message.
+
+ * "git stash" learned --include-untracked option.
+
+ * "git submodule update" used to stop at the first error updating a
+ submodule; it now goes on to update other submodules that can be
+ updated, and reports the ones with errors at the end.
+
+ * "git upload-pack" and "git receive-pack" learned to pretend only a
+ subset of the refs exist in a repository. This may help a site to
+ put many tiny repositories into one repository (this would not be
+ useful for larger repositories as repacking would be problematic).
+
+ * "git verify-pack" has been rewritten to use the "index-pack" machinery
+ that is more efficient in reading objects in packfiles.
+
+ * test scripts for gitweb tried to run even when CGI-related perl modules
+ are not installed; it now exits early when they are unavailable.
+
+Also contains various documentation updates and minor miscellaneous
+changes.
+
+
+Fixes since v1.7.6
+------------------
+
+Unless otherwise noted, all the fixes in 1.7.6.X maintenance track are
+included in this release.
+
+ * "git branch --set-upstream @{-1} foo" did not expand @{-1} correctly.
+ (merge e9d4f74 mg/branch-set-upstream-previous later to 'maint').
+
+ * "git branch -m" and "git checkout -b" incorrectly allowed the tip
+ of the branch that is currently checked out updated.
+ (merge 55c4a67 ci/forbid-unwanted-current-branch-update later to 'maint').
+
+ * "git clone" failed to clone locally from a ".git" file that itself
+ is not a directory but is a pointer to one.
+ (merge 9b0ebc7 nd/maint-clone-gitdir later to 'maint').
+
+ * "git clone" from a local repository that borrows from another
+ object store using a relative path in its objects/info/alternates
+ file did not adjust the alternates in the resulting repository.
+ (merge e6baf4a1 jc/maint-clone-alternates later to 'maint').
+
+ * "git describe --dirty" did not refresh the index before checking the
+ state of the working tree files.
+ (cherry-pick bb57148 ac/describe-dirty-refresh later to 'maint').
+
+ * "git ls-files ../$path" that is run from a subdirectory reported errors
+ incorrectly when there is no such path that matches the given pathspec.
+ (merge 0f64bfa cb/maint-ls-files-error-report later to 'maint').

browser.<tool>.path::
Override the path for the given tool that may be used to
environment variable (see linkgit:curl[1]). This can be overridden
on a per-remote basis; see remote.<name>.proxy
+http.cookiefile::
+ File containing previously stored cookie lines which should be used
+ in the git http session, if they match the server. The file format
+ of the file to read cookies from should be plain HTTP headers or

+
http.sslVerify::
Whether to verify the SSL certificate when fetching or pushing
over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
--patience::
Generate a diff using the "patience diff" algorithm.
---stat[=<width>[,<name-width>]]::
+--stat[=<width>[,<name-width>[,<count>]]]::
Generate a diffstat. You can override the default
output width for 80-column terminal by `--stat=<width>`.
The width of the filename part can be controlled by
giving another width to it separated by a comma.
+ By giving a third parameter `<count>`, you can limit the
+ output to the first `<count>` lines, followed by
+ `...` if there are more.
++
+These parameters can also be set individually with `--stat-width=<width>`,
+`--stat-name-width=<name-width>` and `--stat-count=<count>`.

--reject::
These flags are passed to the 'git apply' (see linkgit:git-apply[1])
program that applies
details. If `--remote` is used then only the configuration of
the remote repository takes effect.
+tar.<format>.command::
+ This variable specifies a shell command through which the tar
+ output generated by `git archive` should be piped. The command
+ is executed using the shell with the generated tar file on its
+ standard input, and should produce the final output on its
+ standard output. Any compression-level options will be passed
+ to the command (e.g., "-9"). An output file with the same
+ extension as `<format>` will be use this format if no other
+ format is given.
++
+The "tar.gz" and "tgz" formats are defined automatically and default to
+`gzip -cn`. You may override them with custom commands.
+
+tar.<format>.remote::
+ If true, enable `<format>` for use by remote clients via
+ linkgit:git-upload-archive[1]. Defaults to false for
+ user-defined formats, but true for the "tar.gz" and "tgz"
+ formats.

on the subcommand:
git bisect help
- git bisect start [<bad> [<good>...]] [--] [<paths>...]
+ git bisect start [
--no-checkout] [<bad> [<good>...]] [--] [<paths>...]
git bisect bad [<rev>]
git bisect good [<rev>...]
git bisect skip [(<rev>|<range>)...]
with the status of the real test to let the "git bisect run" command loop
determine the eventual outcome of the bisect session.
+OPTIONS
+-------
+--no-checkout::
++
+Do not checkout the new working tree at each iteration of the bisection
+process. Instead just update a special reference named 'BISECT_HEAD' to make
+it point to the commit that should be tested.
++
+This option may be useful when the test you would perform in each step
+does not require a checked out tree.
++
+If the repository is bare, `--no-checkout` is assumed.
+
EXAMPLES
--------
This shows that you can do without a run script if you write the test
on a single line.
+* Locate a good region of the object graph in a damaged repository
++
+------------
+$ git bisect start HEAD <known-good-commit> [ <boundary-commit> ... ] --no-checkout
+$ git bisect run sh -c '
+ GOOD=$(git for-each-ref "--format=%(objectname)" refs/bisect/good-*) &&
+ git rev-list --objects BISECT_HEAD --not $GOOD >tmp.$$ &&
+ git pack-objects --stdout >/dev/null <tmp.$$
+ rc=$?
+ rm -f tmp.$$
+ test $rc = 0'
+
+------------
++
+In this case, when 'git bisect run' finishes, bisect/bad will refer to a commit that
+has at least one parent whose reachable graph is fully traversable in the sense
+required by 'git pack objects'.
+
+
SEE ALSO
--------
link:git-bisect-lk2009.html[Fighting regressions with git bisect],
--abbrev=<length>::
Alter the sha1's minimum display length in the output listing.
- The default value is 7.
+ The default value is 7 and can be overridden by the `core.abbrev`
+ config option.
--no-abbrev::
Display the full sha1s in the output listing rather than abbreviating them.

DESCRIPTION
-----------
OPTIONS
-------
+-a, --all::
+ List all attributes that are associated with the specified
+ paths. If this option is used, then 'unspecified' attributes
+ will not be included in the output.
+

Read file names from stdin instead of from the command-line.
\--::
Interpret all preceding arguments as attributes and all following
- arguments as path names. If not supplied, only the first argument will

EXAMPLES
--------
-git cherry-pick master::
+`git cherry-pick master`::
Apply the change introduced by the commit at the tip of the
master branch and create a new commit with this change.
-git cherry-pick ..master::
-git cherry-pick ^HEAD master::
+`git cherry-pick ..master`::
+`git cherry-pick ^HEAD master`::
Apply the changes introduced by all commits that are ancestors
of master but not of HEAD to produce new commits.
-git cherry-pick master{tilde}4 master{tilde}2::
+`git cherry-pick master{tilde}4 master{tilde}2`::
Apply the changes introduced by the fifth and third last
commits pointed to by master and create 2 new commits with
these changes.
-git cherry-pick -n master~1 next::
+`git cherry-pick -n master~1 next`::
Apply to the working tree and the index the changes introduced
by the second last commit pointed to by master and by the last
commit pointed to by next, but do not create any commit with
these changes.
-git cherry-pick --ff ..next::
+`git cherry-pick --ff ..next`::
If history is linear and HEAD is an ancestor of next, update
the working tree and advance the HEAD pointer to match next.
are in next but not HEAD to the current branch, creating a new
commit for each new change.
-git rev-list --reverse master \-- README | git cherry-pick -n --stdin::
+`git rev-list --reverse master \-- README | git cherry-pick -n --stdin`::
Apply the changes introduced by all commits on the master
branch that touched README to the working tree and index,
Specify the directory from which templates will be used;
(See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
+--config <key>=<value>::
+-c <key>=<value>::
+ Set a configuration variable in the newly-created repository;
+ this takes effect immediately after the repository is
+ initialized, but before the remote history is fetched or any
+ files checked out. The key is in the same format as expected by
+ linkgit:git-config[1] (e.g., `core.eol=true`). If multiple
+ values are given for the same key, each value will be written to
+ the config file. This makes it safe, for example, to add
+ additional fetch refspecs to the origin remote.
+
--depth <depth>::
Create a 'shallow' clone with a history truncated to the
specified number of revisions. A shallow repository has a
your working tree are temporarily stored to a staging area
called the "index" with 'git add'. A file can be
reverted back, only in the index but not in the working tree,
-to that of the last commit with `git reset HEAD -- <file>`,
+to that of the last commit with `git reset HEAD \-- <file>`,
which effectively reverts 'git add' and prevents the changes to
this file from participating in the next commit. After building
the state to be committed incrementally with these commands,
allow that. So fake a tagger to be able to fast-import the
output.
+--use-done-feature::
+ Start the stream with a 'feature done' stanza, and terminate
+ it with a 'done' command.
+
--no-data::
Skip output of blob objects and instead refer to blobs via
their original SHA-1 hash. This is useful when rewriting the
when the `cat-blob` command is encountered in the stream.
The default behaviour is to write to `stdout`.
+--done::
+ Require a `done` command at the end of the stream.
+ This option might be useful for detecting errors that
+ cause the frontend to terminate before it has started to
+ write a stream.
+
--export-pack-edges=<file>::
After creating a packfile, print a line of data to
<file> listing the filename of the packfile and the last
standard output. This command is optional and is not needed
to perform an import.
+`done`::
+ Marks the end of the stream. This command is optional
+ unless the `done` feature was requested using the
+ `--done` command line option or `feature done` command.
+
`cat-blob`::
Causes fast-import to print a blob in 'cat-file --batch'
format to the file descriptor set with `--cat-blob-fd` or
(``cm@example.com''). `LT` and `GT` are the literal less-than (\x3c)
and greater-than (\x3e) symbols. These are required to delimit
the email address from the other fields in the line. Note that
-`<name>` is free-form and may contain any sequence of bytes, except
-`LT` and `LF`. It is typically UTF-8 encoded.
+`<name>` and `<email>` are free-form and may contain any sequence
+of bytes, except `LT`, `GT` and `LF`. `<name>` is typically UTF-8 encoded.
The time of the change is specified by `<when>` using the date format
that was selected by the \--date-format=<fmt> command line option.
(see OPTIONS, above).
import-marks::
+import-marks-if-exists::
Like --import-marks except in two respects: first, only one
- "feature import-marks" command is allowed per stream;
- second, an --import-marks= command-line option overrides
- any "feature import-marks" command in the stream.
+ "feature import-marks" or "feature import-marks-if-exists"
+ command is allowed per stream; second, an --import-marks=
+ or --import-marks-if-exists command-line option overrides
+ any of these "feature" commands in the stream; third,
+ "feature import-marks-if-exists" like a corresponding
+ command-line option silently skips a nonexistent file.
cat-blob::
ls::
Versions of fast-import not supporting notes will exit
with a message indicating so.
+done::
+ Error out if the stream ends without a 'done' command.
+ Without this feature, errors causing the frontend to end
+ abruptly at a convenient point in the stream can go
+ undetected.
`option`
~~~~~~~~
* cat-blob-fd
* force
+`done`
+~~~~~~
+If the `done` feature is not in use, treated as if EOF was read.
+This can be used to tell fast-import to finish early.
+
+If the `--done` command line option or `feature done` command is
+in use, the `done` command is mandatory and marks the end of the
+stream.
+

-git gui blame Makefile::
+`git gui blame Makefile`::
Show the contents of the file 'Makefile' in the current
working directory, and provide annotations for both the
uncommitted changes (if any) are explicitly attributed to
'Not Yet Committed'.
-git gui blame v0.99.8 Makefile::
+`git gui blame v0.99.8 Makefile`::

example the file is read from the object database and not
the working directory.
-git gui blame --line=100 Makefile::
+`git gui blame --line=100 Makefile`::
Loads annotations as described above and automatically
scrolls the view to center on line '100'.

+`git citool`::
Same as `git gui citool` (above).
-git gui browser maint::
+`git gui browser maint`::

Shows all commits that are in any of local branches but not in
any of remote-tracking branches for 'origin' (what you have that
origin doesn't).
-git log master --not --remotes=*/master::

EXAMPLES
--------
-git merge-file README.my README README.upstream::
+`git merge-file README.my README README.upstream`::
combines the changes of README.my and README.upstream since README,
tries to merge them and writes the result into README.my.
-git merge-file -L a -L b -L c tmp/a123 tmp/b234 tmp/c345::
+`git merge-file -L a -L b -L c tmp/a123 tmp/b234 tmp/c345`::
merges tmp/a123 and tmp/c345 with the base tmp/b234, but uses labels
`a` and `c` instead of `tmp/a123` and `tmp/c345`.

Works like `git push <remote>`, where <remote> is the
current branch's remote (or `origin`, if no remote is
configured for the current branch).
-git push origin::
+`git push origin`::
Without additional configuration, works like

the ones in the examples below) can be configured as the default for
`git push origin`.
-git push origin :::
+`git push origin :`::
Push "matching" branches to `origin`. See
<refspec> in the <<OPTIONS,OPTIONS>> section above for a
description of "matching" branches.
-git push origin master::
+`git push origin master`::
Find a ref that matches `master` in the source repository
(most likely, it would find `refs/heads/master`), and update
the same ref (e.g. `refs/heads/master`) in `origin` repository
with it. If `master` did not exist remotely, it would be
created.
-git push origin HEAD::
+`git push origin HEAD`::
A handy way to push the current branch to the same name on the
remote.
-git push origin master:satellite/master dev:satellite/dev::
+`git push origin master:satellite/master dev:satellite/dev`::
Use the source ref that matches `master` (e.g. `refs/heads/master`)
to update the ref that matches `satellite/master` (most probably
`refs/remotes/satellite/master`) in the `origin` repository, then
do the same for `dev` and `satellite/dev`.
-git push origin HEAD:master::
+`git push origin HEAD:master`::
Push the current branch to the remote ref matching `master` in the
`origin` repository. This form is convenient to push the current
branch without thinking about its local name.
-git push origin master:refs/heads/experimental::
+`git push origin master:refs/heads/experimental`::
Create the branch `experimental` in the `origin` repository
by copying the current `master` branch. This form is only
needed to create a new branch or tag in the remote repository when
the local name and the remote name are different; otherwise,
the ref name on its own will work.
-git push origin :experimental::
+`git push origin :experimental`::
Find a ref that matches `experimental` in the `origin` repository
(e.g. `refs/heads/experimental`), and delete it.
-git push origin {plus}dev:master::
+`git push origin {plus}dev:master`::
Update the origin repository's master branch with the dev branch,
allowing non-fast-forward updates. *This can leave unreferenced
commits dangling in the origin repository.* Consider the

argument specifies a URL; it is usually of the form
'<transport>://<address>', but any arbitrary string is possible.
+The 'GIT_DIR' environment variable is set up for the remote helper

When git encounters a URL of the form '<transport>://<address>', where
'<transport>' is a protocol that it cannot handle natively, it
should see linkgit:git-reset[1], particularly the '--hard' option. If
you want to extract specific files as they were in another commit, you
should see linkgit:git-checkout[1], specifically the `git checkout

+gitnamespaces(7)
+================
+
+NAME
+----
+gitnamespaces - Git namespaces
+
+DESCRIPTION
+-----------
+
+Git supports dividing the refs of a single repository into multiple
+namespaces, each of which has its own branches, tags, and HEAD. Git can
+expose each namespace as an independent repository to pull from and push
+to, while sharing the object store, and exposing all the refs to
+operations such as linkgit:git-gc[1].
+
+Storing multiple repositories as namespaces of a single repository
+avoids storing duplicate copies of the same objects, such as when
+storing multiple branches of the same source. The alternates mechanism
+provides similar support for avoiding duplicates, but alternates do not
+prevent duplication between new objects added to the repositories
+without ongoing maintenance, while namespaces do.
+
+To specify a namespace, set the `GIT_NAMESPACE` environment variable to
+the namespace. For each ref namespace, git stores the corresponding
+refs in a directory under `refs/namespaces/`. For example,
+`GIT_NAMESPACE=foo` will store refs under `refs/namespaces/foo/`. You
+can also specify namespaces via the `--namespace` option to
+linkgit:git[1].
+
+Note that namespaces which include a `/` will expand to a hierarchy of
+namespaces; for example, `GIT_NAMESPACE=foo/bar` will store refs under
+`refs/namespaces/foo/refs/namespaces/bar/`. This makes paths in
+`GIT_NAMESPACE` behave hierarchically, so that cloning with
+`GIT_NAMESPACE=foo/bar` produces the same result as cloning with
+`GIT_NAMESPACE=foo` and cloning from that repo with `GIT_NAMESPACE=bar`. It
+also avoids ambiguity with strange namespace paths such as `foo/refs/heads/`,
+which could otherwise generate directory/file conflicts within the `refs`
+directory.
+
+linkgit:git-upload-pack[1] and linkgit:git-receive-pack[1] rewrite the
+names of refs as specified by `GIT_NAMESPACE`. git-upload-pack and
+git-receive-pack will ignore all references outside the specified
+namespace.
+
+The smart HTTP server, linkgit:git-http-backend[1], will pass
+GIT_NAMESPACE through to the backend programs; see
+linkgit:git-http-backend[1] for sample configuration to expose
+repository namespaces as repositories.
+
+For a simple local test, you can use linkgit:git-remote-ext[1]:
+
+----------
+git clone ext::'git --namespace=foo %s /tmp/prefixed.git'
+----------
+
+SECURITY
+--------
+
+Anyone with access to any namespace within a repository can potentially
+access objects from any other namespace stored in the same repository.
+You can't directly say "give me object ABCD" if you don't have a ref to
+it, but you can do some other sneaky things like:
+
+. Claiming to push ABCD, at which point the server will optimize out the
+ need for you to actually send it. Now you have a ref to ABCD and can
+ fetch it (claiming not to have it, of course).
+
+. Requesting other refs, claiming that you have ABCD, at which point the
+ server may generate deltas against ABCD.
+
+None of this causes a problem if you only host public repositories, or
+if everyone who may read one namespace may also read everything in every
+other namespace (for instance, if everyone in an organization has read
+permission to every repository).

+
+* Prepare an array of `struct git_attr_check` to define the list of
+ attributes you would want to check. To populate this array, you would
+ need to define necessary attributes by calling `git_attr()` function.
+
+* Call `git_check_attr()` to check the attributes for the path.
+
+* Inspect `git_attr_check` structure to see how each of the attribute in
+ the array is defined for the path.
+
+
Example
-------
{
if (check[0].attr)
return; /* already done */
- check[0].attr = git_attr("crlf", 4);
- check[1].attr = git_attr("ident", 5);
+ check[0].attr = git_attr("crlf");
+ check[1].attr = git_attr("ident");
}
------------
-. Call `git_checkattr()` with the prepared array of `struct git_attr_check`:
+. Call `git_check_attr()` with the prepared array of `struct git_attr_check`:
------------
const char *path;
setup_check();
- git_checkattr(path, ARRAY_SIZE(check), check);
+ git_check_attr(path, ARRAY_SIZE(check), check);
------------
. Act on `.value` member of the result, left in `check[]`:
}
------------
-(JC)
+
+Querying All Attributes
+-----------------------
+
+To get the values of all attributes associated with a file:
+
+* Call `git_all_attrs()`, which returns an array of `git_attr_check`
+ structures.
+
+* Iterate over the `git_attr_check` array to examine the attribute
+ names and values. The name of the attribute described by a
+ `git_attr_check` object can be retrieved via
+ `git_attr_name(check[i].attr)`. (Please note that no items will be
+ returned for unset attributes, so `ATTR_UNSET()` will return false
+ for all returned `git_array_check` objects.)
+
+* Free the `git_array_check` array.

+If you're willing to trade off (much) longer build time for a later
+faster git you can also do a profile feedback build with
+
+ $ make profile-all
+ # make prefix=... install
+
+This will run the complete test suite as training workload and then
+rebuild git with the generated profile feedback. This results in a git
+which is a few percent faster on CPU intensive workloads. This
+may be a good tradeoff for distribution packagers.
+
+Note that the profile feedback build stage currently generates
+a lot of additional compiler warnings.

+- You can configure gitweb further using the per-instance gitweb configuration file;
by default this is a file named gitweb_config.perl in the same place as
gitweb.cgi script. You can control the default place for the config file
using the GITWEB_CONFIG build configuration variable, and you can set it
GITWEB_CONFIG_SYSTEM build configuration variable, and override it
through the GITWEB_CONFIG_SYSTEM environment variable.
+ Note that if per-instance configuration file exists, then system-wide

+ behavior. On the other hand changing current behavior would break backwards
+ compatibility and can lead to unexpected changes in gitweb behavior.
+ Therefore gitweb also looks for common system-wide configuration file,
+ normally /etc/gitweb-common.conf (set during build time using build time
+ configuration variable GITWEB_CONFIG_COMMON, set it at runtime using
+ environment variable with the same name). Settings from per-instance or
+ system-wide configuration file override those from common system-wide
+ configuration file.
+
- The gitweb config file is a fragment of perl code. You can set variables
using "our $variable = value"; text from "#" character until the end
of a line is ignored. See perlsyn(1) for details.

Runtime gitweb configuration
----------------------------
-You can adjust gitweb behaviour using the file specified in `GITWEB_CONFIG`
-(defaults to 'gitweb_config.perl' in the same directory as the CGI), and
-as a fallback `GITWEB_CONFIG_SYSTEM` (defaults to /etc/gitweb.conf).
+Gitweb obtains configuration data from the following sources in the
+following order:
+
+1. built-in values (some set during build stage),
+2. common system-wide configuration file (`GITWEB_CONFIG_COMMON`,
+ defaults to '/etc/gitweb-common.conf'),
+3. either per-instance configuration file (`GITWEB_CONFIG`, defaults to
+ 'gitweb_config.perl' in the same directory as the installed gitweb),
+ or if it does not exists then system-wide configuration file
+ (`GITWEB_CONFIG_SYSTEM`, defaults to '/etc/gitweb.conf').
+
+Values obtained in later configuration files override values obtained earlier
+in above sequence.
+
+You can read defaults in system-wide GITWEB_CONFIG_SYSTEM from GITWEB_CONFIG
+by adding
+
+ read_config_file($GITWEB_CONFIG_SYSTEM);
+
+at very beginning of per-instance GITWEB_CONFIG file. In this case
+settings in said per-instance file will override settings from
+system-wide configuration file. Note that read_config_file checks
+itself that the $GITWEB_CONFIG_SYSTEM file exists.
+
The most notable thing that is not configurable at compile time are the
optional features, stored in the '%features' variable.
# Enable text search, which will list the commits which match author,
# committer or commit text to a given string. Enabled by default.
# Project specific override is not supported.
+ #
+ # Note that this controls all search features, which means that if
+ # it is disabled, then 'grep' and 'pickaxe' search would also be
+ # disabled.

- * we are looking at the official format, not the experimental
- * one.
+ * We must determine if the buffer contains the standard
+ * zlib-deflated stream or the experimental format based
+ * on the in-pack object format. Compare the header byte
+ * for each format:
+ *
+ * RFC1950 zlib w/ deflate : 0www1000 : 0 <= www <= 7
+ * Experimental pack-based : Stttssss : ttt = 1,2,3,4
+ *
+ * If bit 7 is clear and bits 0-3 equal 8, the buffer MUST be
+ * in standard loose-object format, UNLESS it is a Git-pack
+ * format object *exactly* 8 bytes in size when inflated.
+ *
+ * However, RFC1950 also specifies that the 1st 16-bit word
+ * must be divisible by 31 - this checksum tells us our buffer
+ * is in the standard format, giving a false positive only if
+ * the 1st word of the Git-pack format object happens to be
+ * divisible by 31, ie:
+ * ((byte0 * 256) + byte1) % 31 = 0
+ * => 0ttt10000www1000 % 31 = 0
+ *
+ * As it happens, this case can only arise for www=3 & ttt=1
+ * - ie, a Commit object, which would have to be 8 bytes in
+ * size. As no Commit can be that small, we find that the
+ * combination of these two criteria (bitmask & checksum)
+ * can always correctly determine the buffer format.

+test_description='Correctly identify and parse loose object headers
+
+There are two file formats for loose objects - the original standard
+format, and the experimental format introduced with Git v1.4.3, later
+deprecated with v1.5.3. Although Git no longer writes the
+experimental format, objects in both formats must be read, with the
+format for a given file being determined by the header.
+
+Detecting file format based on header is not entirely trivial, not
+least because the first byte of a zlib-deflated stream will vary
+depending on how much memory was allocated for the deflation window
+buffer when the object was written out (for example 4KB on Android,
+rather that 32KB on a normal PC).
+
+The loose objects used as test vectors have been generated with the
+following Git versions:
+
+standard format: Git v1.7.4.1
+experimental format: Git v1.4.3 (legacyheaders=false)
+standard format, deflated with 4KB window size: Agit/JGit on Android
