pass st.st_size as hint for strbuf_readlink()Jeff King Tue, 24 Jul 2018 10:51:39 +0000 (06:51 -0400)

pass st.st_size as hint for strbuf_readlink()

When we initially added the strbuf_readlink() function in
b11b7e13f4 (Add generic 'strbuf_readlink()' helper function,
2008-12-17), the point was that we generally have a _guess_
as to the correct size based on the stat information, but we
can't necessarily trust it.

Over the years, a few callers have grown up that simply pass
in 0, even though they have the stat information. Let's have
them pass in their hint for consistency (and in theory
efficiency, since it may avoid an extra resize/syscall loop,
but neither location is probably performance critical).

Note that st.st_size is actually an off_t, so in theory we
need xsize_t() here. But none of the other callsites use it,
and since this is just a hint, it doesn't matter either way
(if we wrap we'll simply start with a too-small hint and
then eventually complain when we cannot allocate the
memory).

strbuf: use size_t for length in intermediate variables

A few strbuf functions store the length of a strbuf in a
temporary variable. We should always use size_t for this, as
it's possible for a strbuf to exceed an "int" (e.g., a 2GB
string on a 64-bit system). This is unlikely in practice,
but we should try to behave sensibly on silly or malicious
input.

reencode_string: use size_t for string lengths

The iconv interface takes a size_t, which is the appropriate
type for an in-memory buffer. But our reencode_string_*

reencode_string: use st_add/st_mult helpersJeff King Tue, 24 Jul 2018 10:50:10 +0000 (06:50 -0400)

reencode_string: use st_add/st_mult helpers

When converting a string with iconv, if the output buffer
isn't big enough, we grow it. But our growth is done without
any concern for integer overflow. So when we add:

outalloc = sofar + insz * 2 + 32;

we may end up wrapping outalloc (which is a size_t), and
allocating a too-small buffer. We then manipulate it
further:

outsz = outalloc - sofar - 1;

and feed outsz back to iconv. If outalloc is wrapped and
smaller than sofar, we'll end up with a small allocation but
feed a very large outsz to iconv, which could result in it
overflowing the buffer.

Can we use this to construct an attack wherein the victim
clones a repository with a very large commit object with an
encoding header, and running "git log" reencodes it into
utf8, causing an overflow?

An attack of this sort is likely impossible in practice.
"sofar" is how many output bytes we've written total, and
"insz" is the number of input bytes remaining. Imagine our
input doubles in size as we output it (which is easy to do
by converting latin1 to utf8, for example), and that we
start with N input bytes. Our initial output buffer also
starts at N bytes, so after the first call we'd have N/2
input bytes remaining (insz), and have written N bytes
(sofar). That means our next allocation will be
(N + N/2 * 2 + 32) bytes, or (2N + 32).

We can therefore overflow a 32-bit size_t with a commit
message that's just under 2^31 bytes, assuming it consists
mostly of "doubling" sequences (e.g., latin1 0xe1 which
becomes utf8 0xc3 0xa1).

But we'll never make it that far with such a message. We'll
be spending 2^31 bytes on the original string. And our
initial output buffer will also be 2^31 bytes. Which is not
going to succeed on a system with a 32-bit size_t, since
there will be other things using the address space, too. The
initial malloc will fail.

If we imagine instead that we can triple the size when
converting, then our second allocation becomes
(N + 2/3N * 2 + 32), or (7/3N + 32). That still requires two
allocations of 3/7 of our address space (6/7 of the total)
to succeed.

If we imagine we can quadruple, it becomes (5/2N + 32); we
need to be able to allocate 4/5 of the address space to
succeed.

This might start to get plausible. But is it possible to get
a 4-to-1 increase in size? Probably if you're converting to
some obscure encoding. But since git defaults to utf8 for
its output, that's the likely destination encoding for an
attack. And while there are 4-character utf8 sequences, it's
unlikely that you'd be able find a single-byte source
sequence in any encoding.

So this is certainly buggy code which should be fixed, but
it is probably not a useful attack vector.

fetch: send "refs/tags/" prefix upon CLI refspecsJonathan Tan Tue, 5 Jun 2018 21:40:36 +0000 (14:40 -0700)

fetch: send "refs/tags/" prefix upon CLI refspecs

When performing tag following, in addition to using the server's
"include-tag" capability to send tag objects (and emulating it if the
server does not support that capability), "git fetch" relies upon the
presence of refs/tags/* entries in the initial ref advertisement to
locally create refs pointing to the aforementioned tag objects. When
using protocol v2, refs/tags/* entries in the initial ref advertisement
may be suppressed by a ref-prefix argument, leading to the tag object
being downloaded, but the ref not being created.

Commit dcc73cf7ff ("fetch: generate ref-prefixes when using a configured
refspec", 2018-05-18) ensured that "refs/tags/" is always sent as a ref
prefix when "git fetch" is invoked with no refspecs, but not when "git
fetch" is invoked with refspecs. Extend that functionality to make it
work in both situations.

This also necessitates a change another test which tested ref
advertisement filtering using tag refs - since tag refs are sent by
default now, the test has been switched to using branch refs instead.

coccinelle: put sane filenames into output patches

Coccinelle outputs its suggested transformations as patches, whose
header looks something like this:

--- commit.c
+++ /tmp/cocci-output-19250-7ae78a-commit.c

Note the lack of 'diff --opts <old> <new>' line, the differing number
of path components on the --- and +++ lines, and the nonsensical
filename on the +++ line. 'patch -p0' can still apply these patches,
as it takes the filename to be modified from the --- line. Alas, 'git
apply' can't, because it takes the filename from the +++ line, and
then complains about the nonexisting file.

Pass the '--patch .' options to Coccinelle via the SPATCH_FLAGS 'make'
variable, as it seems to make it generate proper context diff patches,
with the header starting with a 'diff ...' line and containing sane
filenames. The resulting 'contrib/coccinelle/*.cocci.patch' files
then can be applied both with 'git apply' and 'patch' (even without
'-p0').

coccinelle: exclude sha1dc source files from static analysis

sha1dc is an external library, that we carry in-tree for convenience
or grab as a submodule, so there is no use in applying our semantic
patches to its source files.

Therefore, exclude sha1dc's source files from Coccinelle's static
analysis.

This change also makes the static analysis somewhat faster: presumably
because of the heavy use of repetitive macro declarations, applying
the semantic patches 'array.cocci' and 'swap.cocci' to 'sha1dc/sha1.c'
takes over half a minute each on my machine, which amounts to about a
third of the runtime of applying these two semantic patches to the
whole git source tree.

t7406: avoid failures solely due to timing issues

Regression tests are automated tests which try to ensure a specific
behavior. The idea is: if the test case fails, the behavior indicated in
the test case's title regressed.

If a regression test that fails, even occasionally, for any reason other
than to indicate the particular regression(s) it tries to catch, it is
less useful than when it really only fails when there is a bug in the
(non-test) code that needs to be fixed.

In the instance of the test case "submodule update --init --recursive
from subdirectory" of the script t7406-submodule-update.sh, the exact
output of a recursive clone is compared with a pre-generated one. And
this is a racy test because the structure of the submodules only
guarantees a *partial* order. The 'none' and the 'rebasing' submodules
*can* be cloned in any order, which means that a mismatch with the
hard-coded order does not necessarily indicate a bug in the tested code.

See for example:
https://git-for-windows.visualstudio.com/git/_build/results?buildId=14035&view=logs

To prevent such false positives from unnecessarily costing time when
investigating test failures, let's take the exact order of the lines out
of the equation by sorting them before comparing them.

This test script seems not to have any more test cases that try to
verify any specific order in which recursive clones process the
submodules, therefore this is the only test case that is changed in this
manner.

travis-ci: fail if Coccinelle static analysis found something to transform

Coccinelle's and in turn 'make coccicheck's exit code only indicates
that Coccinelle managed to finish its analysis without any errors
(e.g. no unknown --options, no missing files, no syntax errors in the
semantic patches, etc.), but it doesn't indicate whether it found any
undesired code patterns to transform or not. To find out the latter,
one has to look closer at 'make coccicheck's standard output and look
for lines like:

SPATCH result: contrib/coccinelle/<something>.cocci.patch

And this only indicates that there is something to transform, but to
see what the suggested transformations are one has to actually look
into those '*.cocci.patch' files.

This makes the automated static analysis build job on Travis CI not
particularly useful, because it neither draws our attention to
Coccinelle's findings, nor shows the actual findings. Consequently,
new topics introducing undesired code patterns graduated to master
on several occasions without anyone noticing.

The only way to draw attention in such an automated setting is to fail
the build job. Therefore, modify the 'ci/run-static-analysis.sh'
build script to check all the resulting '*.cocci.patch' files, and
fail the build job if any of them turns out to be not empty. Include
those files' contents, i.e. Coccinelle's suggested transformations, in
the build job's trace log, so we'll know why it failed.

(there is quite large variation between build job runtimes). More

Update messages in preparation for i18nNguyễn Thái Ngọc Duy Sat, 21 Jul 2018 07:49:19 +0000 (09:49 +0200)

Update messages in preparation for i18n

Many messages will be marked for translation in the following
commits. This commit updates some of them to be more consistent and
reduce diff noise in those commits. Changes are

- keep the first letter of die(), error() and warning() in lowercase
- no full stop in die(), error() or warning() if it's single sentence
messages
- indentation
- some messages are turned to BUG(), or prefixed with "BUG:" and will
not be marked for i18n
- some messages are improved to give more information
- some messages are broken down by sentence to be i18n friendly
(on the same token, combine multiple warning() into one big string)
- the trailing \n is converted to printf_ln if possible, or deleted
if not redundant
- errno_errno() is used instead of explicit strerror()

t9300: wait for background fast-import process to die... SZEDER Gábor Thu, 19 Jul 2018 22:26:41 +0000 (00:26 +0200)

t9300: wait for background fast-import process to die after killing it

The five new tests added to 't9300-fast-import.sh' in 30e215a65c
(fast-import: checkpoint: dump branches/tags/marks even if
object_count==0, 2017-09-28), all with the prefix "V:" in their test
description, run 'git fast-import' in the background and then 'kill'
it as part of a 'test_when_finished' cleanup command. When this test
script is executed with Bash, some or even all of these tests tend to
pollute the test script's stderr, and messages about terminated
processes end up on the terminal:

$ bash ./t9300-fast-import.sh
<... snip ...>
ok 179 - V: checkpoint helper does not get stuck with extra output
/<...>/test-lib-functions.sh: line 388: 28383 Terminated git fast-import $options 0<&8 1>&9
ok 180 - V: checkpoint updates refs after reset
./t9300-fast-import.sh: line 3210: 28401 Terminated git fast-import $options 0<&8 1>&9
ok 181 - V: checkpoint updates refs and marks after commit
ok 182 - V: checkpoint updates refs and marks after commit (no new objects)
./test-lib.sh: line 634: line 3250: 28485 Terminated git fast-import $options 0<&8 1>&9
ok 183 - V: checkpoint updates tags after tag
./t9300-fast-import.sh: line 3264: 28510 Terminated git fast-import $options 0<&8 1>&9

After a background child process terminates, its parent Bash process
always outputs a message like those above to stderr, even when in
non-interactive mode.

But how do some of these messages end up on the test script's stderr,
why don't we get them from all five tests, and why do they come from
different file/line locations? Well, after sending the TERM signal to
the background child process, it takes a little while until that
process receives the signal and terminates, and then it takes another
while until the parent process notices it. During this time the
parent Bash process is continuing execution, and by the time it
notices that its child terminated it might have already left
'test_eval_inner_' and its stderr is not redirected to /dev/null
anymore. That's why such a message can appear on the test script's
stderr, while other times, when the child terminates fast and/or the
parent shell is slow enough, the message ends up in /dev/null, just
like any other output of the test does. Bash always adds the file
name and line number of the code location it was about to execute when
it notices the termination of its child process as a prefix to that
message, hence the varying and sometimes totally unrelated location
prefixes in those messages (e.g. line 388 in 'test-lib-functions.sh'
is 'test_verify_prereq', and I saw such a message pointing to
'say_color' as well).

Prevent these messages from appearing on the test script's stderr by
'wait'-ing on the pid of the background 'git fast-import' process
after sending it the TERM signal. This ensures that the executing
shell's stderr is still redirected when the shell notices the
termination of its child process in the background, and that these
messages get a consistent file/line location prefix.

Note that this is not an issue when the test script is run with Bash
and '-v', because then these messages are supposed to go to the test
script's stderr anyway, and indeed all of them do; though the
sometimes seemingly random file/line prefixes could be confusing
still. Similarly, it's not an issue with Bash and '--verbose-log'
either, because then all messages go to the log file as they should.
Finally, it's not an issue with some other shells (I tried dash, ksh,
ksh93 and mksh) even without any of the verbose options, because they
don't print messages like these in non-interactive mode in the first
place.

Add test cases to cover the new X509/gpgsm support. Most of them
resemble existing ones. They just switch the format to x509 and set the
signingkey when creating signatures. Validation of signatures does not
need any configuration of git, it does need gpgsm to be configured to
trust the key(-chain).
Several of the testcases build on top of existing gpg testcases.
The commit ships a self-signed key for committer@example.com and

xdiff/xhistogram: move index allocation into find_lcsStefan Beller Thu, 19 Jul 2018 18:56:20 +0000 (11:56 -0700)

xdiff/xhistogram: move index allocation into find_lcs

This fixes a memory issue when recursing a lot, which can be reproduced as

seq 1 100000 >one
seq 1 4 100000 >two
git diff --no-index --histogram one two

Before this patch, histogram_diff would call itself recursively before
calling free_index, which would mean a lot of memory is allocated during
the recursion and only freed afterwards. By moving the memory allocation
(and its free call) into find_lcs, the memory is free'd before we recurse,
such that memory is reused in the next step of the recursion instead of
using new memory.

This addresses only the memory pressure, not the run time complexity,
that is also awful for the corner case outlined above.

Helpful in understanding the code (in addition to the sparse history of
this file), was https://stackoverflow.com/a/32367597 which reproduces
most of the code comments of the JGit implementation.

diff.c: add white space mode to move detection that allows indent changes

The option of --color-moved has proven to be useful as observed on the
mailing list. However when refactoring sometimes the indentation changes,
for example when partitioning a functions into smaller helper functions
the code usually mostly moved around except for a decrease in indentation.

To just review the moved code ignoring the change in indentation, a mode
to ignore spaces in the move detection as implemented in a previous patch
would be enough. However the whole move coloring as motivated in commit
2e2d5ac (diff.c: color moved lines differently, 2017-06-30), brought
up the notion of the reviewer being able to trust the move of a "block".

As there are languages such as python, which depend on proper relative
indentation for the control flow of the program, ignoring any white space
change in a block would not uphold the promises of 2e2d5ac that allows
reviewers to pay less attention to the inside of a block, as inside
the reviewer wants to assume the same program flow.

This new mode of white space ignorance will take this into account and will
only allow the same white space changes per line in each block. This patch
even allows only for the same change at the beginning of the lines.

As this is a white space mode, it is made exclusive to other white space
modes in the move detection.

This patch brings some challenges, related to the detection of blocks.
We need a wide net to catch the possible moved lines, but then need to
narrow down to check if the blocks are still intact. Consider this
example (ignoring block sizes):

- A
- B
- C
+ A
+ B
+ C

At the beginning of a block when checking if there is a counterpart
for A, we have to ignore all space changes. However at the following
lines we have to check if the indent change stayed the same.

Checking if the indentation change did stay the same, is done by computing
the indentation change by the difference in line length, and then assume
the change is only in the beginning of the longer line, the common tail
is the same. That is why the test contains lines like:

- <TAB> A
...
+ A <TAB>
...

As the first line starting a block is caught using a compare function that
ignores white spaces unlike the rest of the block, where the white space
delta is taken into account for the comparison, we also have to think about
the following situation:

- A
- B
- A
- B
+ A
+ B
+ A
+ B

When checking if the first A (both in the + and - lines) is a start of
a block, we have to check all 'A' and record all the white space deltas
such that we can find the example above to be just one block that is
indented.

add core.usereplacerefs config optionJeff King Wed, 18 Jul 2018 20:45:25 +0000 (16:45 -0400)

add core.usereplacerefs config option

We can already disable replace refs using a command line
option or environment variable, but those are awkward to
apply universally. Let's add a config option to do the same
thing.

That raises the question of why one might want to do so
universally. The answer is that replace refs violate the
immutability of objects. For instance, if you wanted to
cache the diff between commit XYZ and its parent, then in
theory that never changes; the hash XYZ represents the total
state. But replace refs violate that; pushing up a new ref
may create a completely new diff.

The obvious "if it hurts, don't do it" answer is not to
create replace refs if you're doing this kind of caching.
But for a site hosting arbitrary repositories, they may want
to allow users to share replace refs with each other, but
not actually respect them on the site (because the caching
is more important than the replace feature).

gpg-interface: introduce new config to select per gpg format program

Supporting multiple signing formats we will have the need to configure a
custom program each. Add a new config value to cater for that.

gpg-interface: do not hardcode the key string len anymore

gnupg does print the keyid followed by a space and the signer comes
next. The same pattern is also used in gpgsm, but there the key length
would be 40 instead of 16. Instead of hardcoding the expected length,
find the first space and calculate it.
Input that does not match the expected format will be ignored now,
before we jumped to found+17 which might have been behind the end of an
unexpected string.

gpg-interface: introduce an abstraction for multiple gpg formats

Create a struct that holds the format details for the supported formats.
At the moment that is still just "openpgp". This commit prepares for the
introduction of more formats, that might use other programs and match
other signatures.

commit-graph: add repo arg to graph readersJonathan Tan Wed, 11 Jul 2018 22:42:42 +0000 (15:42 -0700)

commit-graph: add repo arg to graph readers

Add a struct repository argument to the functions in commit-graph.h that
read the commit graph. (This commit does not affect functions that write
commit graphs.)

Because the commit graph functions can now read the commit graph of any
repository, the global variable core_commit_graph has been removed.
Instead, the config option core.commitGraph is now read on the first
time in a repository that a commit is attempted to be parsed using its
commit graph.

This commit includes a test that exercises the functionality on an
arbitrary repository that is not the_repository.

commit-graph: store graph in struct object_store

Instead of storing commit graphs in static variables, store them in
struct object_store. There are no changes to the signatures of existing
functions - they all still only support the_repository, and support for
other instances of struct repository will be added in a subsequent
commit.

commit-graph: refactor preparing commit graph

Two functions in the code (1) check if the repository is configured for
commit graphs, (2) call prepare_commit_graph(), and (3) check if the
graph exists. Move (1) and (3) into prepare_commit_graph(), reducing
duplication of code.
