6 years agoread-cache: fix index corruption with index v4
Thomas Gummerer [Thu, 7 Sep 2017 19:24:12 +0000 (20:24 +0100)]
read-cache: fix index corruption with index v4

ce012deb98 ("read-cache: avoid allocating every ondisk entry when
writing", 2017-08-21) changed the way cache entries are written to the
index file.  While previously it wrote the name to an struct that was
allocated using xcalloc(), it now uses ce_write() directly.  Previously
ce_namelen - common bytes were written to the cache entry, which would
automatically make it nul terminated, as it was allocated using calloc.

Now we are writing ce_namelen - common + 1 bytes directly from the
ce->name to the index.  If CE_STRIP_NAME however gets set in the split
index case ce->ce_namelen is set to 0 without changing the actual
ce->name buffer.  When index-v4, this results in the first character of
ce->name being written out instead of just a terminating nul charcter.

As index-v4 requires the terminating nul character as terminator of
the name when reading it back, this results in a corrupted index.

Fix that by only writing ce_namelen - common bytes directly from
ce->name to the index, and adding the nul terminator in an extra call to
ce_write.

This bug was turned up by setting TEST_GIT_INDEX_VERSION = 4 in
config.mak and running the test suite (t1700 specifically broke).

7 years agoread-cache: avoid allocating every ondisk entry when writing
Kevin Willford [Mon, 21 Aug 2017 21:24:32 +0000 (15:24 -0600)]
read-cache: avoid allocating every ondisk entry when writing

When writing the index for each entry an ondisk struct will be
allocated and freed in ce_write_entry.  We can do better by
using a ondisk struct on the stack for each entry.

This is accomplished by using a stack ondisk_cache_entry_extended
outside looping through the entries in do_write_index.  Only the
fixed fields of this struct are used when writing and depending on
whether it is extended or not the flags2 field will be written.
The name field is not used and instead the cache_entry name field
is used directly when writing out the name.  Because ce_write is
using a buffer and memcpy to fill the buffer before flushing to disk,
we don't have to worry about doing multiple ce_write calls.

Running the p0007-write-cache.sh tests would save anywhere
between 3-7% when the index had over a million entries with no
performance degradation on small repos.

git.c: ignore pager.* when launching builtin as dashed external

When running, e.g., `git -c alias.bar=foo bar`, we expand the alias and
execute `git-foo` as a dashed external. This is true even if git foo is
a builtin. That is on purpose, and is motivated in a comment which was
added in commit 441981bc ("git: simplify environment save/restore
logic", 2016-01-26).

Shortly before we launch a dashed external, and unless we have already
found out whether we should use a pager, we check `pager.foo`. This was
added in commit 92058e4d ("support pager.* for external commands",
2011-08-18). If the dashed external is a builtin, this does not match
that commit's intention and is arguably wrong, since it would be cleaner
if we let the "dashed external builtin" handle `pager.foo`.

This has not mattered in practice, but a recent patch taught `git-tag`
to ignore `pager.tag` under certain circumstances. But, when started
using an alias, it doesn't get the chance to do so, as outlined above.
That recent patch added a test to document this breakage.

Do not check `pager.foo` before launching a builtin as a dashed
external, i.e., if we recognize the name of the external as a builtin.
Change the test to use `test_expect_success`.

cannot (and should not) know what the arguments to git foo are supposed
to achieve.

In practice this means that, e.g., `git -c pager.tag tag -a new-tag`

connect: reject dashed arguments for proxy commands

If you have a GIT_PROXY_COMMAND configured, we will run it
with the host/port on the command-line. If a URL contains a
mischievous host like "--foo", we don't know how the proxy
command may handle it. It's likely to break, but it may also
do something dangerous and unwanted (technically it could
even do something useful, but that seems unlikely).

We should err on the side of caution and reject this before
we even run the command.

The hostname check matches the one we do in a similar
circumstance for ssh. The port check is not present for ssh,
but there it's not necessary because the syntax is "-p
<port>", and there's no ambiguity on the parsing side.

It's not clear whether you can actually get a negative port
to the proxy here or not. Doing:

  git fetch git://remote:-1234/repo.git

keeps the "-1234" as part of the hostname, with the default
port of 9418. But it's a good idea to keep this check close
to the point of running the command to make it clear that
there's no way to circumvent it (and at worst it serves as a
belt-and-suspenders check).

When commands like "git fetch" talk with ssh://$rest_of_URL/, the

then spawns the underlying "ssh" program by formulating argv[] array
that has:

 - the path to ssh command taken from GIT_SSH_COMMAND, etc.

 - dashed options like '-batch' (for Tortoise), '-p <port>' as

which obviously is bogus, but depending on the actual value of

t/lib-proto-disable: restore protocol.allow after config tests

The tests for protocol.allow actually set that variable in
the on-disk config, run a series of tests, and then never
clean up after themselves. This means that whatever tests we
run after have protocol.allow=never, which may influence
their results.

In most cases we either exit after running these tests, or
do another round of test_proto(). In the latter case, this happens to
work because:

  1. Tests of the GIT_ALLOW_PROTOCOL environment variable
     override the config.

  2. Tests of the specific config "protocol.foo.allow"
     override the protocol.allow config.

  3. The next round of protocol.allow tests start off by
     setting the config to a known value.

However, it's a land-mine waiting to trap somebody adding
new tests to one of the t581x test scripts. Let's make sure
we clean up after ourselves.
