ref-filter.c: pass empty-string as NULL to atom parsersTaylor Blau Mon, 2 Oct 2017 16:10:34 +0000 (09:10 -0700)

ref-filter.c: pass empty-string as NULL to atom parsers

Peff points out that different atom parsers handle the empty
"sub-argument" list differently. An example of this is the format
"%(refname:)".

Since callers often use `string_list_split` (which splits the empty
string with any delimiter as a 1-ary string_list containing the empty
string), this makes handling empty sub-argument strings non-ergonomic.

Let's fix this by declaring that atom parser implementations must
not care about distinguishing between the empty string "%(refname:)"
and no sub-arguments "%(refname)". Current code aborts, either with
"unrecognised arg" (e.g. "refname:") or "does not take args"
(e.g. "body:") as an error message.

sub-process: use child_process.args instead of child_process.argv

Currently the argv is only allocated on the stack, and then assigned to
process->argv. When the start_subprocess function goes out of scope,
the local argv variable is eliminated from the stack, but the pointer is
still kept around in process->argv.

Much later when we try to access the same process->argv in
finish_command, this leads us to access a memory location that no longer
contains what we want. As argv0 is only used for printing errors, this
is not easily noticed in normal git operations. However when running
t0021-conversion.sh through valgrind, valgrind rightfully complains:

==21024== Invalid read of size 8
==21024== at 0x2ACF64: finish_command (run-command.c:869)

==21024== 1504 bytes below stack pointer

These days, the child_process structure has its own args array, and
the standard way to set up its argv[] is to use that one, instead of
assigning to process->argv to point at an array that is outside.
Use that facility automatically fixes this issue.

http-push: fix construction of hex value from pathThomas Gummerer Tue, 3 Oct 2017 19:57:12 +0000 (20:57 +0100)

http-push: fix construction of hex value from path

The get_oid_hex_from_objpath takes care of creating a oid from a
pathname. It does this by memcpy'ing the first two bytes of the path to
the "hex" string, then skipping the '/', and then copying the rest of the
path to the "hex" string. Currently it fails to increase the pointer to
the hex string, so the second memcpy invocation just mashes over what
was copied in the first one, and leaves the last two bytes in the string
uninitialized.

This breaks valgrind in t5540, although the test passes without
valgrind:

==5490== Use of uninitialised value of size 8
==5490== at 0x13C6B5: hexval (cache.h:1238)

Fix this by correctly incrementing the pointer to the "hex" variable, so
the first two bytes are left untouched by the memcpy call, and the last
two bytes are correctly initialized.

cat-file: handle NULL object_context.pathJeff King Thu, 21 Sep 2017 06:21:40 +0000 (02:21 -0400)

cat-file: handle NULL object_context.path

Commit dc944b65f1 (get_sha1_with_context: dynamically
allocate oc->path, 2017-05-19) changed the rules that
callers must follow for seeing if we parsed a path in the
object name. The rules switched from "check if the oc.path
buffer is empty" to "check if the oc.path pointer is NULL".
But that commit forgot to update some sites in
cat_one_file(), meaning we might dereference a NULL pointer.

You can see this by making a path-aware request like
--textconv without specifying --path, and giving an object
name that doesn't have a path in it. Like:

git cat-file --textconv HEAD

which will reliably segfault.

test-lint: echo -e (or -E) is not portable

Some implementations of `echo` support the '-e' option to enable
backslash interpretation of the following string.
As an addition, they support '-E' to turn it off.

However, none of these are portable, POSIX doesn't even mention them,
and many implementations don't support them.

A check for '-n' is already done in check-non-portable-shell.pl,
extend it to cover '-n', '-e' or '-E'.

for_each_string_list_item: avoid undefined behavior... Michael Haggerty Wed, 20 Sep 2017 05:27:05 +0000 (22:27 -0700)

for_each_string_list_item: avoid undefined behavior for empty list

If you pass a newly initialized or newly cleared `string_list` to
`for_each_string_list_item()`, then the latter does

for (
item = (list)->items; /* NULL */
item < (list)->items + (list)->nr; /* NULL + 0 */
++item)

Even though this probably works almost everywhere, it is undefined
behavior, and it could plausibly cause highly-optimizing compilers to
misbehave. C99 section 6.5.6 paragraph 8 explains:

If both the pointer operand and the result point to elements
of the same array object, or one past the last element of the
array object, the evaluation shall not produce an overflow;
otherwise, the behavior is undefined.

and (6.3.2.3.3) a null pointer does not point to anything.

Guard the loop with a NULL check to make the intent crystal clear to
even the most pedantic compiler. A suitably clever compiler could let
the NULL check only run in the first iteration, but regardless, this
overhead is likely to be dwarfed by the work to be done on each item.

This problem was noticed by Coverity.

[jn: using a NULL check instead of a placeholder empty list;
fleshed out the commit message based on mailing list discussion]

gc: call fscanf() with %<len>s, not %<len>c, when reading hostname

Earlier in this codepath, we (ab)used "%<len>c" to read the hostname
recorded in the lockfile into locking_host[HOST_NAME_MAX + 1] while
substituting <len> with the actual value of HOST_NAME_MAX.

This turns out to be incorrect, as it is an instruction to read
exactly the specified number of bytes. Because we are trying to
read at most that many bytes, we should be using "%<len>s" instead.

archive: don't add empty directories to archivesRené Scharfe Tue, 12 Sep 2017 22:43:57 +0000 (00:43 +0200)

archive: don't add empty directories to archives

While git doesn't track empty directories, git archive can be tricked
into putting some into archives. One way is to construct an empty tree
object, as t5004 does. While that is supported by the object database,
it can't be represented in the index and thus it's unlikely to occur in
the wild.

Another way is using the literal name of a directory in an exclude
pathspec -- its contents are are excluded, but the directory stub is
included. That's inconsistent: exclude pathspecs containing wildcards
don't leave empty directories in the archive.

Yet another way is have a few levels of nested subdirectories (e.g.
d1/d2/d3/file1) and ignoring the entries at the leaves (e.g. file1).
The directories with the ignored content are ignored as well (e.g. d3),
but their empty parents are included (e.g. d2).

As empty directories are not supported by git, they should also not be
written into archives. If an empty directory is really needed then it
can be tracked and archived by placing an empty .gitignore file in it.

There already is a mechanism in place for suppressing empty directories.
When read_tree_recursive() encounters a directory excluded by a pathspec
then it enters it anyway because it might contain included entries. It
calls the callback function before it is able to decide if the directory
is actually needed. For that reason git archive adds directories to a
queue and writes entries for them only when it encounters the first
child item -- but currently only if pathspecs with wildcards are used.

Queue *all* directories, no matter if there even are pathspecs present.
This prevents git archive from writing entries for empty directories in
all cases.

refs: strip out not allowed flags from ref_transaction_update

Callers are only allowed to pass certain flags into
ref_transaction_update, other flags are internal to it. To prevent
mistakes from the callers, strip the internal only flags out before
continuing.

This was noticed because of a compiler warning gcc 7.1.1 issued about
passing a NULL parameter as second parameter to memcpy (through
hashcpy):

In file included from refs.c:5:0:
refs.c: In function ‘ref_transaction_verify’:
cache.h:948:2: error: argument 2 null where non-null expected [-Werror=nonnull]
memcpy(sha_dst, sha_src, GIT_SHA1_RAWSZ);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from git-compat-util.h:165:0,
from cache.h:4,
from refs.c:5:
/usr/include/string.h:43:14: note: in a call to function ‘memcpy’ declared here
extern void *memcpy (void *__restrict __dest, const void *__restrict __src,
^~~~~~

The call to hascpy in ref_transaction_add_update is protected by the
passed in flags, but as we only add flags there, gcc notices
REF_HAVE_NEW or REF_HAVE_OLD flags could be passed in from the outside,
which would potentially result in passing in NULL as second parameter to
memcpy.

Fix both the compiler warning, and make the interface safer for its
users by stripping the internal flags out.

cvsimport: shell-quote variable used in backticks

We run `git rev-parse` though the shell, and quote its
argument only with single-quotes. This prevents most
metacharacters from being a problem, but misses the obvious
case when $name itself has single-quotes in it. We can fix
this by applying the usual shell-quoting formula.

shell: drop git-cvsserver support by defaultJeff King Mon, 11 Sep 2017 15:27:51 +0000 (11:27 -0400)

shell: drop git-cvsserver support by default

The git-cvsserver script is old and largely unmaintained
these days. But git-shell allows untrusted users to run it
out of the box, significantly increasing its attack surface.

Let's drop it from git-shell's list of internal handlers so
that it cannot be run by default. This is not backwards
compatible. But given the age and development activity on
CVS-related parts of Git, this is likely to impact very few
users, while helping many more (i.e., anybody who runs
git-shell and had no intention of supporting CVS).

There's no configuration mechanism in git-shell for us to
add a boolean and flip it to "off". But there is a mechanism
for adding custom commands, and adding CVS support here is
fairly trivial. Let's document it to give guidance to
anybody who really is still running cvsserver.

Merge branch 'ma/pager-per-subcommand-action' into maint

The "tag.pager" configuration variable was useless for those who
actually create tag objects, as it interfered with the use of an
editor. A new mechanism has been introduced for commands to enable
pager depending on what operation is being carried out to fix this,
and then "git tag -l" is made to run pager by default.

If this works out OK, I think there are low-hanging fruits in
other commands like "git branch" that outputs long list in one mode
while taking input in another.

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

Some versions of GnuPG fails to kill gpg-agent it auto-spawned
and such a left-over agent can interfere with a test. Work it
around by attempting to kill one before starting a new test.

commit-tree: do not complete line in -F inputRoss Kabus Thu, 7 Sep 2017 14:41:11 +0000 (10:41 -0400)

commit-tree: do not complete line in -F input

"git commit-tree -F <file>", unlike "cat <file> | git
commit-tree" (i.e. feeding the same contents from the standard
input), added a missing final newline when the input ended in an
incomplete line.

Correct this inconsistency by leaving the incomplete line as-is,
as erring on the side of not touching the input is preferrable
and expected for a plumbing command like "commit-tree".

rev-parse: don't trim bisect refnamesJeff King Wed, 6 Sep 2017 11:53:10 +0000 (07:53 -0400)

rev-parse: don't trim bisect refnames

Using for_each_ref_in() with a full refname has always been
a questionable practice, but it became an error with
b9c8e7f2fb (prefix_ref_iterator: don't trim too much,
2017-05-22), making "git rev-parse --bisect" pretty reliably
show a BUG.

Commit 03df567fbf (for_each_bisect_ref(): don't trim
refnames, 2017-06-18) fixed this case for revision.c, but
rev-parse handles this option on its own. We can use the
same solution here (and piggy-back on its test).
