If this extension is used in a repository, then no
operations should run which may drop objects from the object
storage. This can be useful if you are sharing that storage
with other repositories whose refs you cannot see.
For instance, if you do:
$ git clone -s parent child
$ git -C parent config extensions.preciousObjects true
$ git -C parent config core.repositoryformatversion 1
you now have additional safety when running git in the
parent repository. Prunes and repacks will bail with an
error, and `git gc` will skip those operations (it will
continue to pack refs and do other non-object operations).
Older versions of git, when run in the repository, will
fail on every operation.
Note that we do not set the preciousObjects extension by
default when doing a "clone -s", as doing so breaks
backwards compatibility. It is a decision the user should
make explicitly.

Normally we try to avoid bumps of the whole-repository
core.repositoryformatversion field. However, it is
unavoidable if we want to safely change certain aspects of
git in a backwards-incompatible way (e.g., modifying the set
of ref tips that we must traverse to generate a list of
unreachable, safe-to-prune objects).
If we were to bump the repository version for every such
change, then any implementation understanding version `X`
would also have to understand `X-1`, `X-2`, and so forth,
even though the incompatibilities may be in orthogonal parts
of the system, and there is otherwise no reason we cannot
implement one without the other (or more importantly, that
the user cannot choose to use one feature without the other,
weighing the tradeoff in compatibility only for that
particular feature).
This patch documents the existing repositoryformatversion
strategy and introduces a new format, "1", which lets a
repository specify that it must run with an arbitrary set of
extensions. This can be used, for example:
- to inform git that the objects should not be pruned based
only on the reachability of the ref tips (e.g, because it
has "clone --shared" children)
- that the refs are stored in a format besides the usual
"refs" and "packed-refs" directories
Because we bump to format "1", and because format "1"
requires that a running git knows about any extensions
mentioned, we know that older versions of the code will not
do something dangerous when confronted with these new
formats.
For example, if the user chooses to use database storage for
refs, they may set the "extensions.refbackend" config to
"db". Older versions of git will not understand format "1"
and bail. Versions of git which understand "1" but do not
know about "refbackend", or which know about "refbackend"
but not about the "db" backend, will refuse to run. This is
annoying, of course, but much better than the alternative of
claiming that there are no refs in the repository, or
writing to a location that other implementations will not
read.
Note that we are only defining the rules for format 1 here.
We do not ever write format 1 ourselves; it is a tool that
is meant to be used by users and future extensions to
provide safety with older implementations.

Identical to support in `git receive-pack for the config option
`receive.fsck.skiplist`, we now support ignoring given objects in

The optional new config option `receive.fsck.skipList` specifies the path

are to be ignored by `git receive-pack` when `receive.fsckObjects = true`.
This is extremely handy in case of legacy repositories where it would

The intended use case is for server administrators to inspect objects
that are reported by `git push` as being too problematic to enter the
repository, and to add the objects' SHA-1 to a (preferably sorted) file
when the objects are legitimate, i.e. when it is determined that those
problematic objects should be allowed to enter the server.

We already have support in `git receive-pack` to deal with some legacy
repositories which have non-fatal issues.
Let's make `git fsck` itself useful with such repositories, too, by
allowing users to ignore known issues, or at least demote those issues
to mere warnings.
Example: `git -c fsck.missingEmail=ignore fsck` would hide
problems with missing emails in author, committer and tagger lines.
In the same spirit that `git receive-pack`'s usage of the fsck machinery
differs from `git fsck`'s – some of the non-fatal warnings in `git fsck`
are fatal with `git receive-pack` when receive.fsckObjects = true, for
example – we strictly separate the fsck.<msg-id> from the
receive.fsck.<msg-id> settings.

The unsigned long option parsing (including 'k'/'m'/'g' suffix
parsing) is more widely applicable. Add support for OPT_MAGNITUDE
to parse-options.h and change pack-objects.c use this support.
The error behavior on parse errors follows that of OPT_INTEGER. The
name of the option that failed to parse is reported with a brief
message describing the expect format for the option argument and
then the full usage message for the command invoked.
This differs from the previous behavior for OPT_ULONG used in
pack-objects for --max-pack-size and --window-memory which used to
display the value supplied in the error message and did not display
the full usage message.

It can sometimes be useful to examine all objects in the
repository. Normally this is done with "git rev-list --all
--objects", but:
1. That shows only reachable objects. You may want to look
at all available objects.
2. It's slow. We actually open each object to walk the
graph. If your operation is OK with seeing unreachable
objects, it's an order of magnitude faster to just
enumerate the loose directories and pack indices.
You can do this yourself using "ls" and "git show-index",
but it's non-obvious. This patch adds an option to
"cat-file --batch-check" to operate on all available
objects (rather than reading names from stdin).
This is based on a proposal by Charles Bailey to provide a
separate "git list-all-objects" command. That is more
orthogonal, as it splits enumerating the objects from
getting information about them. However, in practice you
will either:
a. Feed the list of objects directly into cat-file anyway,
so you can find out information about them. Keeping it
in a single process is more efficient.
b. Ask the listing process to start telling you more
information about the objects, in which case you will
reinvent cat-file's batch-check formatter.
Adding a cat-file option is simple and efficient. And if you
really do want just the object names, you can always do:
git cat-file --batch-check='%(objectname)' --batch-all-objects

When debugging the pack protocol, it is sometimes useful to
store the verbatim pack that we sent or received on the
wire. Looking at the on-disk result is often not helpful for
a few reasons:
1. If the operation is a clone, we destroy the repo on
failure, leaving nothing on disk.
2. If the pack is small, we unpack it immediately, and the
full pack never hits the disk.
3. If we feed the pack to "index-pack --fix-thin", the
resulting pack has the extra delta bases added to it.
We already have a GIT_TRACE_PACKET mechanism for tracing
packets. Let's extend it with GIT_TRACE_PACKFILE to dump the
verbatim packfile.
There are a few other positive fallouts that come from
rearranging this code:
- We currently disable the packet trace after seeing the
PACK header, even though we may get human-readable lines
on other sidebands; now we include them in the trace.
- We currently try to print "PACK ..." in the trace to
indicate that the packfile has started. But because we
disable packet tracing, we never printed this line. We
will now do so.

The interface to custom low-level merge driver was modeled to be

can produce result solely by looking at three files that hold
contents of common ancestor, ours and theirs. The information we
feed to the external drivers via the command line placeholders %O,
%A, and %B were designed to be purely about contents by giving
names of the temporary files that hold these variants without
exposing the original pathname. No matter where the result goes,
merging the same three variants should produce the same result,
contents is the king, that is the Git way.
The external driver interface, however, is meant to help people to
step outside the Git worldview, and sometimes people want to know
the final path that the resulting merged contents would be stored
in. Expose this to the external drivers via a new placeholder %P.

While parsing the command-line arguments, git-pull stops parsing at the
first unrecognized option, assuming that any subsequent options are for
git-fetch, and can thus be kept in the shell's positional parameters
list, so that it can be passed to git-fetch via the expansion of "$@".
However, certain functions in git-pull assume that the positional
parameters do not contain any options:
* error_on_no_merge_candidates() uses the number of positional
parameters to determine which error message to print out, and will
thus print the wrong message if git-fetch's options are passed in as
well.
* the call to get_remote_merge_branch() assumes that the positional
parameters only contains the optional repo and refspecs, and will
thus silently fail if git-fetch's options are passed in as well.
* --dry-run is a valid git-fetch option, but if provided after any
git-fetch options, it is not recognized by git-pull and thus git-pull
will continue to run the merge or rebase.
Fix these bugs by teaching git-pull to parse git-fetch's options as
well. Add tests to prevent regressions.
This removes the limitation where git-fetch's options have to come after
git-merge's and git-rebase's options on the command line. Update the

It's better to start the man page with a description of what

Reorder the paragraphs such that
- the first short paragraph introduces the submodule concept,
- the second paragraph highlights the usage of the submodule command,
- the third paragraph giving background information, and finally
- the fourth paragraph discusing alternatives such as subtrees and
remotes, which we don't want to be confused with.
This ordering deepens the knowledge on submodules with each paragraph.
First the basic questions like "How/what" will be answered, while the
underlying concepts will be taught at a later time.
Making sure it is not confused with subtrees and remotes is not really
enhancing knowledge of submodules itself, but rather painting the big
picture of git concepts, so you could also argue to have it as the second
paragraph. Personally I think this may confuse readers, specially

Traditionally, we only cared about whitespace breakages introduced
in new lines. Some people want to paint whitespace breakages on old
lines, too. When they see a whitespace breakage on a new line, they
can spot the same kind of whitespace breakage on the corresponding
old line and want to say "Ah, those breakages are there but they
were inherited from the original, so let's not touch them for now."
Introduce `--ws-error-highlight=<kind>` option, that lets them pass
a comma separated list of `old`, `new`, and `context` to specify
what lines to highlight whitespace errors on.

* jk/http-backend-deadlock-2.2:
http-backend: spool ref negotiation requests to buffer
t5551: factor out tag creation
http-backend: fix die recursion with custom handler
When http-backend spawns "upload-pack" to do ref
negotiation, it streams the http request body to
upload-pack, who then streams the http response back to the
client as it reads. In theory, git can go full-duplex; the
client can consume our response while it is still sending
the request. In practice, however, HTTP is a half-duplex
protocol. Even if our client is ready to read and write
simultaneously, we may have other HTTP infrastructure in the
way, including the webserver that spawns our CGI, or any
intermediate proxies.
In at least one documented case[1], this leads to deadlock
when trying a fetch over http. What happens is basically:
1. Apache proxies the request to the CGI, http-backend.
2. http-backend gzip-inflates the data and sends
the result to upload-pack.
3. upload-pack acts on the data and generates output over
the pipe back to Apache. Apache isn't reading because
it's busy writing (step 1).
This works fine most of the time, because the upload-pack
output ends up in a system pipe buffer, and Apache reads
it as soon as it finishes writing. But if both the request
and the response exceed the system pipe buffer size, then we
deadlock (Apache blocks writing to http-backend,
http-backend blocks writing to upload-pack, and upload-pack
blocks writing to Apache).
We need to break the deadlock by spooling either the input
or the output. In this case, it's ideal to spool the input,
because Apache does not start reading either stdout _or_
stderr until we have consumed all of the input. So until we
do so, we cannot even get an error message out to the
client.
The solution is fairly straight-forward: we read the request
body into an in-memory buffer in http-backend, freeing up
Apache, and then feed the data ourselves to upload-pack. But
there are a few important things to note:
1. We limit the in-memory buffer to prevent an obvious
denial-of-service attack. This is a new hard limit on
requests, but it's unlikely to come into play. The
default value is 10MB, which covers even the ridiculous
100,000-ref negotation in the included test (that
actually caps out just over 5MB). But it's configurable
on the off chance that you don't mind spending some
extra memory to make even ridiculous requests work.
2. We must take care only to buffer when we have to. For
pushes, the incoming packfile may be of arbitrary
size, and we should connect the input directly to
receive-pack. There's no deadlock problem here, though,
because we do not produce any output until the whole
packfile has been read.
For upload-pack's initial ref advertisement, we
similarly do not need to buffer. Even though we may
generate a lot of output, there is no request body at
all (i.e., it is a GET, not a POST).

Change typedef each_ref_fn to take a "const struct object_id *oid"
parameter instead of "const unsigned char *sha1".
To aid this transition, implement an adapter that can be used to wrap
old-style functions matching the old typedef, which is now called
"each_ref_sha1_fn"), and make such functions callable via the new
interface. This requires the old function and its cb_data to be
wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be
used as the cb_data for an adapter function, each_ref_fn_adapter().
This is an enormous diff, but most of it consists of simple,
mechanical changes to the sites that call any of the "for_each_ref"
family of functions. Subsequent to this change, the call sites can be
rewritten one by one to use the new interface.

With uploadpack.allowReachableSHA1InWant configuration option set on the
server side, "git fetch" can make a request with a "want" line that names
an object that has not been advertised (likely to have been obtained out
of band or from a submodule pointer). Only objects reachable from the
branch tips, i.e. the union of advertised branches and branches hidden by
transfer.hideRefs, will be processed. Note that there is an associated
cost of having to walk back the history to check the reachability.
This feature can be used when obtaining the content of a certain commit,
for which the sha1 is known, without the need of cloning the whole
repository, especially if a shallow fetch is used. Useful cases are e.g.
repositories containing large files in the history, fetching only the
needed data for a submodule checkout, when sharing a sha1 without telling
which exact branch it belongs to and in Gerrit, if you think in terms of
commits instead of change numbers. (The Gerrit case has already been
solved through allowTipSHA1InWant as every Gerrit change has a ref.)

In a triangular workflow, each branch may have two distinct
points of interest: the @{upstream} that you normally pull
from, and the destination that you normally push to. There
isn't a shorthand for the latter, but it's useful to have.
For instance, you may want to know which commits you haven't
pushed yet:
git log @{push}..
Or as a more complicated example, imagine that you normally
pull changes from origin/master (which you set as your
@{upstream}), and push changes to your own personal fork
(e.g., as myfork/topic). You may push to your fork from
multiple machines, requiring you to integrate the changes
from the push destination, rather than upstream. With this
patch, you can just do:
git rebase @{push}
rather than typing out the full name.
The heavy lifting is all done by branch_get_push; here we
just wire it up to the "@{push}" syntax.

When we create each branch struct, we fill in the
"remote_name" field from the config, and then fill in the
actual "remote" field (with a "struct remote") based on that
name. However, it turns out that nobody really cares about
the latter field. The only two sites that access it at all
are:
1. git-merge, which uses it to notice when the branch does
not have a remote defined. But we can easily replace this
with looking at remote_name instead.
2. remote.c itself, when setting up the @{upstream} merge
config. But we don't need to save the "remote" in the
"struct branch" for that; we can just look it up for
the duration of the operation.
So there is no need to have both fields; they are redundant
with each other (the struct remote contains the name, or you
can look up the struct from the name). It would be nice to
simplify this, especially as we are going to add matching
pushremote config in a future patch (and it would be nice to
keep them consistent).
So which one do we keep and which one do we get rid of?
If we had a lot of callers accessing the struct, it would be
more efficient to keep it (since you have to do a lookup to
go from the name to the struct, but not vice versa). But we
don't have a lot of callers; we have exactly one, so
efficiency doesn't matter. We can decide this based on
simplicity and readability.
And the meaning of the struct value is somewhat unclear. Is
it always the remote matching remote_name? If remote_name is
NULL (i.e., no per-branch config), does the struct fall back
to the "origin" remote, or is it also NULL? These questions
will get even more tricky with pushremotes, whose fallback
behavior is more complicated. So let's just store the name,
which pretty clearly represents the branch.*.remote config.
Any lookup or fallback behavior can then be implemented in
helper functions.

equivalent to passing --no-ff and --ff-only to git-merge. However, if

confusing behavior where pull.ff=false or pull.ff=only is able to
override merge.ff, while pull.ff=true is unable to.

Currently, there is only one attempt to acquire any lockfile, and if
the lock is held by another process, the locking attempt fails
immediately.
This is not such a limitation for loose reference files. First, they
don't take long to rewrite. Second, most reference updates have a
known "old" value, so if another process is updating a reference at
the same moment that we are trying to lock it, then probably the
expected "old" value will not longer be valid, and the update will
fail anyway.
But these arguments do not hold for packed-refs:
* The packed-refs file can be large and take significant time to
rewrite.
* Many references are stored in a single packed-refs file, so it could
be that the other process was changing a different reference than
the one that we are interested in.
Therefore, it is much more likely for there to be spurious lock
conflicts in connection to the packed-refs file, resulting in
unnecessary command failures.
So, if the first attempt to lock the packed-refs file fails, continue
retrying for a configurable length of time before giving up. The
default timeout is 1 second.

3. optionally calling fmt_merge_msg() via prepare_merge_message()
to prepare an auto-generated merge log message, using fake
contents that FETCH_HEAD would have had if these commits were
fetched from the current repository with "git pull . $args..."
Make "git merge FETCH_HEAD" to be the same as the traditional
git merge "$(git fmt-merge-msg <.git/FETCH_HEAD)" $commits
invocation of the command in "git pull", where $commits are the ones
that appear in FETCH_HEAD that are not marked as not-for-merge, by
making it do a bit more, specifically:
- noticing "FETCH_HEAD" is the only "commit" on the command line
and picking the commits that are not marked as not-for-merge as
the list of commits to be merged (substitute for step #1 above);
- letting the resulting list fed to step #2 above;
- doing the step #3 above, using the contents of the FETCH_HEAD
instead of fake contents crafted from the list of commits parsed
in the step #1 above.
Note that this changes the semantics. "git merge FETCH_HEAD" has
always behaved as if the first commit in the FETCH_HEAD file were
directly specified on the command line, creating a two-way merge
whose auto-generated merge log said "merge commit xyz". With this
change, if the previous fetch was to grab multiple branches (e.g.
"git fetch $there topic-a topic-b"), the new world order is to
create an octopus, behaving as if "git pull $there topic-a topic-b"
were run. This is a deliberate change to make that happen, and
can be seen in the changes to t3033 tests.

Merges with an absurd number of parents are still a bad idea because
they do not render well in tools like gitk, but if they are present
in the repository being imported into git then there's no need to
avoid reproducing them faithfully.
In olden times, before v1.6.0-rc0~194 (2008-06-27), git commit-tree
and higher-level tools built on top of it were limited to writing 16
parents for a commit. Nowadays normal git operations are happy to
write more parents when asked, so the motivation for this note in the
fast-import documentation is gone and we can remove it.

Ignoring a merge can be read as ignoring the changes a merge commit
introduces altogether, as if the entire side branch the merge commit
merged was removed from the history. But that is not what happens
if "-p" is not specified. What happens is that the individual
commits a merge commit introduces are replayed in order, and only
any possible merge conflict resolutions or manual amendments to the
merge commit are ignored.
Get this straight in the docs.
Also, do not say that merge commits are *tried* to be recreated. As that is
true almost everywhere it is better left unsaid.

Add $XDG_CONFIG_HOME/git/credentials to the default credential search
path of git-credential-store. This allows git-credential-store to
support user-specific configuration files in accordance with the XDG
base directory specification[1].
[1] http://standards.freedesktop.org/basedir-spec/basedir-spec-0.7.html
~/.git-credentials has a higher precedence than
$XDG_CONFIG_HOME/git/credentials when looking up credentials. This
means that if any duplicate matching credentials are found in the xdg
file (due to ~/.git-credentials being updated by old versions of git or
outdated tools), they will not be used at all. This is to give the user
some leeway in switching to old versions of git while keeping the xdg
directory. This is consistent with the behavior of git-config.
However, the higher precedence of ~/.git-credentials means that as long
as ~/.git-credentials exist, all credentials will be written to the
~/.git-credentials file even if the user has an xdg file as having a
~/.git-credentials file indicates that the user wants to preserve
backwards-compatibility. This is also consistent with the behavior of
git-config.
To make this precedence explicit in docs/git-credential-store, add a new
section FILES that lists out the credential file paths in their order of
precedence, and explain how the ordering affects the lookup, storage and
erase operations.
Also, update the documentation for --file to briefly explain the
operations on multiple files if the --file option is not provided.
Since the xdg file will not be used unless it actually exists, to
prevent the situation where some credentials are present in the xdg file
while some are present in the home file, users are recommended to not
create the xdg file if they require compatibility with old versions of
git or outdated tools. Note, though, that "erase" can be used to
explicitly erase matching credentials from all files.

Most operations that iterate over refs are happy to ignore
broken cruft. However, some operations should be performed
with knowledge of these broken refs, because it is better
for the operation to choke on a missing object than it is to
silently pretend that the ref did not exist (e.g., if we are
computing the set of reachable tips in order to prune
objects).
These processes could just call for_each_rawref, except that
ref iteration is often hidden behind other interfaces. For
instance, for a destructive "repack -ad", we would have to
inform "pack-objects" that we are destructive, and then it
would in turn have to tell the revision code that our
"--all" should include broken refs.
It's much simpler to just set a global for "dangerous"
operations that includes broken refs in all iterations.

If the user enables untracked cache, then

- or move the whole (portable) disk from one machine to another
- or access a shared fs from another machine
there's no guarantee that untracked cache can still function properly.
Record the worktree location and OS footprint in the cache. If it
changes, err on the safe side and disable the cache. The user can
'update-index --untracked-cache' again to make sure all conditions are
met.
This adds a new requirement that setup_git_directory* must be called

If we are expiring reflog entries for a symbolic reference, then how
should --updateref be handled if the newest reflog entry is expired?
Option 1: Update the referred-to reference. (This is what the current
code does.) This doesn't make sense, because the referred-to reference
has its own reflog, which hasn't been rewritten.
Option 2: Update the symbolic reference itself (as in, REF_NODEREF).
This would convert the symbolic reference into a non-symbolic
reference (e.g., detaching HEAD), which is surely not what a user
would expect.
Option 3: Error out. This is plausible, but it would make the
following usage impossible:
git reflog expire ... --updateref --all
Option 4: Ignore --updateref for symbolic references.
We choose to implement option 4.

In "git log --decorate", you would see the commit header like this:
commit ... (HEAD, jc/decorate-leaky-separator-color)
where "commit ... (" is painted in color.diff.commit, "HEAD" in
color.decorate.head, ", " in color.diff.commit, the branch name in
color.decorate.branch and then closing ")" in color.diff.commit.
If you wanted to paint the HEAD and local branch name in the same
color as the body text (perhaps because cyan and green are too faint
on a black-on-white terminal to be readable), you would not want to
have to say
[color "decorate"]
head = black
branch = black
because that you would not be able to reuse same configuration on a
white-on-black terminal. You would naively expect
[color "decorate"]
head = normal
branch = normal
to work, but unfortunately it does not. It paints the string "HEAD"
and the branch name in the same color as the opening parenthesis or
comma between the decoration elements. This is because the code
forgets to reset the color after printing the "prefix" in its own
color.
It theoretically is possible that some people were expecting and
relying on that the attribute set as the "diff.commit" color, which
is used to draw these opening parenthesis and inter-item comma, is
inherited by the drawing of branch names, but it is not how the
coloring works everywhere else.

"git apply" was not very careful about reading from, removing,
updating and creating paths outside the working tree (under
--index/--cached) or the current directory (when used as a
replacement for GNU patch).
* jc/apply-beyond-symlink:
apply: do not touch a file beyond a symbolic link
apply: do not read from beyond a symbolic link
apply: do not read from the filesystem under --index
apply: reject input that touches outside the working area
The documentation of 'git submodule update' has several problems:
1) It mentions that value 'none' of submodule.$name.update can be
overridden by --checkout, but other combinations of configuration
values and command line options are not mentioned.
2) The documentation of submodule.$name.update is scattered across three
places, which is confusing.
3) The documentation of submodule.$name.update in gitmodules.txt is
incorrect, because the code always uses the value from .git/config
and never from .gitmodules.
4) Documentation of --force was incomplete, because it is only effective
in case of checkout method of update.
Fix all these problems by documenting submodule.*.update in
git-submodule.txt and make everybody else refer to it.

The strbuf API was explained between the API documentation and in
the header file. Move missing bits to strbuf.h so that programmers
can check only one place for all necessary information.
* jk/strbuf-doc-to-header:
strbuf.h: group documentation for trim functions
strbuf.h: drop boilerplate descriptions of strbuf_split_*
strbuf.h: reorganize api function grouping headers
strbuf.h: format asciidoc code blocks as 4-space indent
strbuf.h: drop asciidoc list formatting from API docs
strbuf.h: unify documentation comments beginnings
strbuf.h: integrate api-strbuf.txt documentation

The variable was documented in git-mailinfo.txt, but not in config.txt.
The detailed documentation is still the one of --scissors in
git-mailinfo.txt, but we give enough information here to let the user
understand what it is about, and to make it easy to find it (e.g.
searching ">8" and "8<" finds it).

The clone subcommand has long had support for excluding
subdirectories, but sync has not. This is a nuisance,
since as soon as you do a sync, any changed files that
were initially excluded start showing up.
Move the "exclude" command-line option into the parent
class; the actual behavior was already present there so
it simply had to be exposed.

By default, a patch that affects outside the working area (either a
Git controlled working tree, or the current working directory when
"git apply" is used as a replacement of GNU patch) is rejected as a
mistake (or a mischief). Git itself does not create such a patch,
unless the user bends over backwards and specifies a non-standard
prefix to "git diff" and friends.
When `git apply` is used as a "better GNU patch", the user can pass
the `--unsafe-paths` option to override this safety check. This
option has no effect when `--index` or `--cached` is in use.
The new test was stolen from Jeff King with slight enhancements.
Note that a few new tests for touching outside the working area by
following a symbolic link are still expected to fail at this step,
but will be fixed in later steps.

We may want to say something about command line option names in the
new section as well, but for now, let's make sure everybody is clear
on how to structure and name their configuration variables.
The text for the rules are partly taken from the log message of

add.ignore-errors, 2010-12-01).
