merge-recursive: restore accidentally dropped setting of path

In commit 8daec1df03de ("merge-recursive: switch from (oid,mode) pairs
to a diff_filespec", 2019-04-05), we actually switched from
(oid,mode,path) triplets to a diff_filespec -- but most callsites in the
patch only needed to worry about oid and mode so the commit message
focused on that.  The oversight in the commit message apparently spilled
over to the code as well; one of the dozen or so callsites accidentally
dropped the setting of the path in the conversion.  Restore the path
setting in that location.

Also, this pointed out that our testsuite was lacking a good rename/add
test, at least one that involved the need for merge content with the
rename.  Add such a test, and since rename/add vs. add/rename could
possibly be important, redo the merge the opposite direction to make
sure we don't have issues with the direction of the merge.  These
testcases failed before restoring the setting of path, but with the
paths appropriately set the testcases both pass.

list-objects-filter: disable 'sparse:path' filters

If someone wants to use as a filter a sparse file that is in the
repository, something like "--filter=sparse:oid=<ref>:<path>"
already works.

So 'sparse:path' is only interesting if the sparse file is not in
the repository. In this case though the current implementation has
a big security issue, as it makes it possible to ask the server to
read any file, like for example /etc/password, and to explore the
filesystem, as well as individual lines of files.

If someone is interested in using a sparse file that is not in the
repository as a filter, then at the minimum a config option, such
as "uploadpack.sparsePathFilter", should be implemented first to
restrict the directory from which the files specified by
'sparse:path' can be read.

For now though, let's just disable 'sparse:path' filters.

missing check: if "arg" is empty to begin with, we fail to notice.

This could happen with long option by writing like

  git diff --inter-hunk-context= blah blah

Before 16ed6c97cc (diff-parseopt: convert --inter-hunk-context,

opt_arg() and does detect this correctly.

This restores the bahvior for --inter-hunk-context and make sure all
other integer options are handled the same (sane) way. For OPT_ABBREV
this is new behavior. But it makes it consistent with the rest.

PS. OPT_MAGNITUDE has similar code but git_parse_ulong() does detect

diff-parseopt: correct variable types that are used by parseopt

Most number-related OPT_ macros store the value in an 'int'
variable. Many of the variables in 'struct diff_options' have a
different type, but during the conversion to using parse_options() I
failed to notice and correct.

The problem was reported on s360x which is a big-endian
architechture. The variable to store '-w' option in this case is
xdl_opts, 'long' type, 8 bytes. But since parse_options() assumes
'int' (4 bytes), it will store bits in the wrong part of xdl_opts. The
problem was found on little-endian platforms because parse_options()
will accidentally store at the right part of xdl_opts.

There aren't much to say about the type change (except that 'int' for
xdl_opts should still be big enough, since Windows' long is the same
size as 'int' and nobody has complained so far). Some safety checks may

5 years agosend-email: fix regression in sendemail.identity parsing
Ævar Arnfjörð Bjarmason [Fri, 17 May 2019 19:55:44 +0000 (21:55 +0200)] 
send-email: fix regression in sendemail.identity parsing

Fix a regression in my recent 3494dfd3ee ("send-email: do defaults ->
config -> getopt in that order", 2019-05-09). I missed that the
$identity variable needs to be extracted from the command-line before
we do the config reading, as it determines which config variable we
should read first. See [1] for the report.

The sendemail.identity feature was added back in
34cc60ce2b ("send-email: Add support for SSL and SMTP-AUTH",
2007-09-03), there were no tests to assert that it worked properly.

So let's fix both the regression, and add some tests to assert that
this is being parsed properly. While I'm at it I'm adding a
--no-identity option to go with --[to|cc|bcc] variable, since the
semantics are similar. It's like to/cc/bcc except that unlike those we
don't support multiple identities, but we could now easily add it
support for it if anyone cares.

In just fixing the --identity command-line parsing bug I discovered
that a narrow fix to that wouldn't do. In read_config() we had a state
machine that would only set config values if they weren't set already,
and thus by proxy we wouldn't e.g. set "to" based on sendemail.to if
we'd seen sendemail.gmail.to before, with --identity=gmail.

I'd modified some of the relevant code in 3494dfd3ee, but just
reverting to that wouldn't do, since it would bring back the
regression fixed in that commit.

Refactor read_config() do what we actually mean here. We don't want to
set a given sendemail.VAR if a sendemail.$identity.VAR previously set
it. The old code was conflating this desire with the hardcoded
defaults for these variables, and as discussed in 3494dfd3ee that was
never going to work. Instead pass along the state of whether an
identity config set something before, as distinguished from the state
of the default just being false, or the default being a non-bool or
true (e.g. --transferencoding).

I'm still not happy with the test coverage here, e.g. there's nothing
testing sendemail.smtpEncryption, but I only have so much time to fix
this code.

5 years agogrep: fail if call could output and name is null
Emily Shaffer [Thu, 23 May 2019 20:23:56 +0000 (13:23 -0700)] 
grep: fail if call could output and name is null

grep_source(), which performs much of the work for Git's grep library,
allows passing an arbitrary struct grep_source which represents the text
which grep_source() should search to match a pattern in the provided
struct grep_opt. In most callers, the grep_source::name field is set to
an appropriate prefix to print before a colon when a result matches:

README:Git is an Open Source project covered by the GNU General

One caller, grep_buffer(), leaves the grep_source::name field set to
NULL because there isn't enough context to determine an appropriate name
for this kind of output line. In practice, this has been fine: the only
caller of grep_buffer() is "git log --grep", and that caller sets
grep_opt::status_only, which disables output and only checks whether a
match exists. But this is brittle: a future caller can call
grep_buffer() without grep_opt::status_only set, and as soon as it hits
a match, grep_source() will try to print the match and segfault:

(null):Git is an Open Source project covered by the GNU General

For example, a future caller might want to print all matching lines from
commits which match a regex.

Futureproof by diagnosing early a use of the API that could trigger that
condition, before we know whether the pattern matches:

BUG: grep.c:1783: grep call which could print a name requires
grep_source.name be non-NULL
Aborted

This way, the caller's author gets an indication of how to fix the issue
- by providing grep_source::name or setting grep_opt::status_only - and
they are warned of the potential for a segfault unconditionally, rather
than only if there is a match.

Noticed while adding such a call to a tutorial on revision walks.

When updating the topo-order walk in b454241 (revision.c: generation-based

If a commit-graph exists with computed generation numbers, then a
'git rev-list --topo-order -n <N> <rev>' query will use those generation
numbers to reduce the number of commits walked before writing N commits.

One caveat put in b454241 (revision.c: generation-based topo-order
algorithm, 2018-11-01) was to not enable the new algorithm for queries
with a revision range "A..B". The logic was placed to walk from "A" and
mark those commits as uninteresting, but the performance was actually
worse than the existing logic in some cases.

The root cause of this performance degradation is that generation
numbers _increase_ the number of commits we walk relative to the
existing heuristic of walking by commit date. While generation numbers
actually guarantee that the algorithm is correct, the existing logic
is very rarely wrong and that added requirement is not worth the cost.

This motivates the planned "corrected commit date" to replace
generation numbers in a future version of Git.

The current change enables the logic to use whatever reachability
index is currently in the commit-graph (generation numbers or
corrected commit date).

The limited flag in struct rev_info forces a full walk of the
commit history (after discovering the A..B range). Previosuly, it
is enabled whenever we see an uninteresting commit. We prevent
enabling the parameter when we are planning to use the reachability
index for a topo-order.

In --interactive mode, "git am --resolved" will try to generate a patch

patch?". To do so it needs the tree of HEAD, which it tries to get with
get_oid_tree(). However, this doesn't yield a tree object; the "tree"
part just means "if you must disambiguate short oids, then prefer trees"
(and we do not need to disambiguate at all, since we are feeding a ref).

Instead, we must parse the oid as a commit (which should always be true
in a non-corrupt repository), and access its tree pointer manually.

This has been broken since the conversion to C in 7ff2683253
(builtin-am: implement -i/--interactive, 2015-08-04), but there was no
test coverage because of interactive-mode's insistence on having a tty.
That was lifted in the previous commit, so we can now add a test for
this case.

Note that before this patch, the test would result in a BUG() which
comes from 3506dc9445 (has_uncommitted_changes(): fall back to empty
tree, 2018-07-11). But before that, we'd have simply segfaulted (and in
fact this is the exact type of case the BUG() added there was trying to

However, this isn't strictly necessary, and makes the tool harder to
