Git v2.12 was shipped with an embarrassing breakage where various
operations that verify paths given from the user stopped dying when
seeing an issue, and instead later triggering segfault.
... and then to down to 'maint'.
* js/realpath-pathdup-fix:
real_pathdup(): fix callsites that wanted it to die on error
t1501: demonstrate NULL pointer access with invalid GIT_WORK_TREE
|
|
Code clean-up and a string truncation fix.
* mm/two-more-xstrfmt:
bisect_next_all: convert xsnprintf to xstrfmt
stop_progress_msg: convert xsnprintf to xstrfmt

The command-line parsing of "git log -L" copied internal data
structures using incorrect size on ILP32 systems.
* vn/line-log-memcpy-size-fix:
line-log: use COPY_ARRAY to fix mis-sized memcpy
|
|
The code to parse "git log -L..." command line was buggy when there
are many ranges specified with -L; overrun of the allocated buffer
has been fixed.
* ax/line-log-range-merge-fix:
line-log.c: prevent crash during union of too many ranges
|
|
The patch subcommand of "git add -i" was meant to have paths
selection prompt just like other subcommand, unlike "git add -p"
directly jumps to hunk selection. Recently, this was broken and
"add -i" lost the paths selection dialog, but it now has been
fixed.
* jk/add-i-patch-do-prompt:
add--interactive: fix missing file prompt for patch mode with "-i"

When a redirected http transport gets an error during the
redirected request, we ignored the error we got from the server,
and ended up giving a not-so-useful error message.
* jt/http-base-url-update-upon-redirect:
http: attempt updating base URL only if no error
|
|
Add 32-bit Linux variant to the set of platforms to be tested with
Travis CI.
* js/travis-32bit-linux:

Reduce authentication round-trip over HTTP when the server supports
just a single authentication method.

In 4ac9006f832 (real_path: have callers use real_pathdup and
strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path())
pattern to use real_pathdup() directly.
The problem with this change is that real_path() calls
strbuf_realpath() with die_on_error = 1 while real_pathdup() calls
it with die_on_error = 0. Meaning that in cases where real_path()
causes Git to die() with an error message, real_pathdup() is silent
and returns NULL instead.
The callers, however, are ill-prepared for that change, as they expect
the return value to be non-NULL (and otherwise the function died
with an appropriate error message).
Fix this by extending real_pathdup()'s signature to accept the
die_on_error flag and simply pass it through to strbuf_realpath(),
and then adjust all callers after a careful audit whether they would
handle NULLs well.

This memcpy meant to get the sizeof a "struct range", not a
"range_set", as the former is what our array holds. Rather
than swap out the types, let's convert this site to
COPY_ARRAY, which avoids the problem entirely (and confirms
that the src and dst types match).
Note for curiosity's sake that this bug doesn't trigger on
I32LP64 systems, but does on ILP32 systems. The mistaken
"struct range_set" has two ints and a pointer. That's 16
bytes on LP64, or 12 on ILP32. The correct "struct range"
type has two longs, which is also 16 on LP64, but only 8 on
ILP32.
Likewise an IL32P64 system would experience the bug.

When Git v2.9.1 was released, it had a bug that showed only on Windows
and on 32-bit systems: our assumption that `unsigned long` can hold
64-bit values turned out to be wrong.
This could have been caught earlier if we had a Continuous Testing
set up that includes a build and test run on 32-bit Linux.
Let's do this (and take care of the Windows build later). This patch
asks Travis CI to install a Docker image with 32-bit libraries and then
goes on to build and test Git using this 32-bit setup.

The existing implementation of range_set_union does not correctly
reallocate memory, leading to a heap overflow when it attempts to union
more than 24 separate line ranges.
For struct range_set *out to grow correctly it must have out->nr set to
the current size of the buffer when it is passed to range_set_grow.
However, the existing implementation of range_set_union only updates
out->nr at the end of the function, meaning that it is always zero
before this. This results in range_set_grow never growing the buffer, as
well as some of the union logic itself being incorrect as !out->nr is
always true.
The reason why 24 is the limit is that the first allocation of size 1
ends up allocating a buffer of size 24 (due to the call to alloc_nr in
ALLOC_GROW). This goes some way to explain why this hasn't been
caught before.
Fix the problem by correctly updating out->nr after reallocating the
range_set. As this results in out->nr containing the same value as the
variable o, replace o with out->nr as well.
Finally, add a new test to help prevent the problem reoccurring in the
future. Thanks to Vegard Nossum for writing the test.

When invoked as "git add -i", each menu interactive menu
option prompts the user to select a list of files. This
includes the "patch" option, which gets the list before
starting the hunk-selection loop.
As "git add -p", it behaves differently, and jumps straight
to the hunk selection loop.
Since 0539d5e6d (i18n: add--interactive: mark patch prompt
for translation, 2016-12-14), the "add -i" case mistakenly
jumps to straight to the hunk-selection loop. Prior to that
commit the distinction between the two cases was managed by
the $patch_mode variable. That commit used $patch_mode for
something else, and moved the old meaning to the "$cmd"
variable. But it forgot to update the $patch_mode check
inside patch_update_cmd() which controls the file-list
behavior.
The simplest fix would be to change that line to check $cmd.
But while we're here, let's use a less obscure name for this
flag: $patch_mode_only, a boolean which tells whether we are
in full-interactive mode or only in patch-mode.

http.c supports HTTP redirects of the form
http://foo/info/refs?service=git-upload-pack
-> http://anything
-> http://bar/info/refs?service=git-upload-pack
(that is to say, as long as the Git part of the path and the query
string is preserved in the final redirect destination, the intermediate
steps can have any URL). However, if one of the intermediate steps
results in an HTTP exception, a confusing "unable to update url base
from redirection" message is printed instead of a Curl error message
with the HTTP exception code.
This was introduced by 2 commits. Commit c93c92f ("http: update base
URLs when we see redirects", 2013-09-28) introduced a best-effort
optimization that required checking if only the "base" part of the URL
differed between the initial request and the final redirect destination,
but it performed the check before any HTTP status checking was done. If
something went wrong, the normal code path was still followed, so this
did not cause any confusing error messages until commit 6628eb4 ("http:
always update the base URL for redirects", 2016-12-06), which taught
http to die if the non-"base" part of the URL differed.
Therefore, teach http to check the HTTP status before attempting to
check if only the "base" part of the URL differed. This commit teaches
http_request_reauth to return early without updating options->base_url
upon an error; the only invoker of this function that passes a non-NULL
"options" is remote-curl.c (through "http_get_strbuf"), which only uses
options->base_url for an informational message in the situations that
this commit cares about (that is, when the return value is not HTTP_OK).
The included test checks that the redirect scheme at the beginning of
this commit message works, and that returning a 502 in the middle of the
redirect scheme produces the correct result. Note that this is different
from the test in commit 6628eb4 ("http: always update the base URL for
redirects", 2016-12-06) in that this commit tests that a Git-shaped URL
(http://.../info/refs?service=git-upload-pack) works, whereas commit
6628eb4 tests that a non-Git-shaped URL
(http://.../info/refs/foo?service=git-upload-pack) does not work (even
though Git is processing that URL) and is an error that is fatal, not
silently swallowed.

This variable needs to be specified to make some types of
non-basic authentication work, but ideally this would just
work out of the box for everyone.
However, simply setting it to "1" by default introduces an
extra round-trip for cases where it _isn't_ useful. We end
up sending a bogus empty credential that the server rejects.
Instead, let's introduce an automatic mode, that works like
this:
1. We won't try to send the bogus credential on the first
request. We'll wait to get an HTTP 401, as usual.
2. After seeing an HTTP 401, the empty-auth hack will kick
in only when we know there is an auth method available
that might make use of it (i.e., something besides
"Basic" or "Digest").
That should make it work out of the box, without incurring
any extra round-trips for people hitting Basic-only servers.
This _does_ incur an extra round-trip if you really want to
use "Basic" but your server advertises other methods (the
emptyauth hack will kick in but fail, and then Git will
actually ask for a password).
The auto mode may incur an extra round-trip over setting
http.emptyauth=true, because part of the emptyauth hack is
to feed this blank password to curl even before we've made a
single request.

By default, we tell curl to use CURLAUTH_ANY, which does not
limit its set of auth methods. However, this results in an
extra round-trip to the server when authentication is
required. After we've fed the credential to curl, it wants
to probe the server to find its list of available methods
before sending an Authorization header.
We can shortcut this by limiting our http_auth_methods by
what the server told us it supports. In some cases (such as
when the server only supports Basic), that lets curl skip
the extra probe request.
The end result should look the same to the user, but you can
use GIT_TRACE_CURL to verify the sequence of requests:
GIT_TRACE_CURL=1 \
git ls-remote https://example.com/repo.git \
2>&1 >/dev/null |
egrep '(Send|Recv) header: (GET|HTTP|Auth)'
Before this patch, hitting a Basic-only server like
github.com results in:
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Recv header: HTTP/1.1 401 Authorization Required
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Recv header: HTTP/1.1 401 Authorization Required
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Send header: Authorization: Basic <redacted>
Recv header: HTTP/1.1 200 OK
And after:
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Recv header: HTTP/1.1 401 Authorization Required
Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1
Send header: Authorization: Basic <redacted>
Recv header: HTTP/1.1 200 OK
The possible downsides are:
- This only helps for a Basic-only server; for a server
with multiple auth options, curl may still send a probe
request to see which ones are available (IOW, there's no
way to say "don't probe, I already know what the server
will say").
- The http_auth_methods variable is global, so this will
apply to all further requests. That's acceptable for
Git's usage of curl, though, which also treats the
credentials as global. I.e., in any given program
invocation we hit only one conceptual server (we may be
redirected at the outset, but in that case that's whose
auth_avail field we'd see).

Not just . and .., but any path that begins with dot is not copied
when copying the template directory to a new repository. You can
customize the template directory, copying some dotfiles might make
sense, but it's actually a good thing not to, because you would not
want to have your git directory copied in every git directory that
is created should you decide to put your template directory under
version control, for example. Plus, it might be used as a feature
by people who would want to exclude some files.
