The code to check the refname we store the fetched result locally did not
bother checking the first 5 bytes of it, presumably assuming that it
always begin with "refs/". For a fetch refspec (or the result of applying
wildcard on one), we always want the RHS to map to something inside
"refs/" hierarchy, so let's spell that rule out in a more explicit way.
It has been observed that curl_multi_timeout may return a very long
timeout value (e.g., 294 seconds and some usec) just before
curl_multi_fdset returns no file descriptors for reading. The
upshot is that select() will hang for a long time -- long enough for
an https handshake to be dropped. The observed behavior is that
the git command will hang at the terminal and never transfer any
data.
This patch is a workaround for a probable bug in libcurl. The bug
only seems to manifest around a very specific set of circumstances:
- curl version (from curl/curlver.h):
#define LIBCURL_VERSION_NUM 0x071307
- git-remote-https running on an ubuntu-lucid VM.
- Connecting through squid proxy running on another VM.
Interestingly, the problem doesn't manifest if a host connects
through squid proxy running on localhost; only if the proxy is on
a separate VM (not sure if the squid host needs to be on a separate
physical machine). That would seem to suggest that this issue
is timing-sensitive.
This patch is more or less in line with a recommendation in the
curl docs about how to behave when curl_multi_fdset doesn't return
and file descriptors:
tree-walk: use enum interesting instead of integer
Commit d688cf0 (tree_entry_interesting(): give meaningful names to
return values - 2011-10-24) converts most of the tree_entry_interesting
values to the new enum, except "never_interesting". This completes the
conversion.
Even though I coded this, I am not sure what use scenarios would benefit
from this option, so the description is unnecessarily negative at this
moment. People who do want to use this feature need to come up with a
more plausible use case and replace it.
filter-branch: use git-sh-setup's ident parsing functions
This saves us some code, but it also reduces the number of
processes we start for each filtered commit. Since we can
parse both author and committer in the same sed invocation,
we save one process. And since the new interface avoids tr,
we save 4 processes.
It also avoids using "tr", which has had some odd
portability problems reported with from Solaris's xpg6
version.
We also tweak one of the tests in t7003 to double-check that
we are properly exporting the variables (because test-lib.sh
exports GIT_AUTHOR_NAME, it will be automatically exported
in subprograms. We override this to make sure that
filter-branch handles it properly itself).

The only ident-parsing function we currently provide is
get_author_ident_from_commit. This is not very
flexible for two reasons:
1. It takes a commit as an argument, and can't read from
commit headers saved on disk.
2. It will only parse authors, not committers.
This patch provides a more flexible interface which will
parse multiple idents from a commit provide on stdin. We can
easily use it as a building block for the current function

You can currently set the output format to --short or
--porcelain. There is no --long, because we default to it
already. However, you may want to override an alias that
uses "--short" to get back to the default.
This requires a little bit of refactoring, because currently
we use STATUS_FORMAT_LONG internally to mean the same as
"the user did not specify anything". By expanding the enum
to include STATUS_FORMAT_NONE, we can distinguish between
the implicit and explicit cases. This effects these
conditions:
1. The user has asked for NUL termination. With NONE, we
currently default to turning on the porcelain mode.
With an explicit --long, we would in theory use NUL
termination with the long mode, but it does not support
it. So we can just complain and die.
2. When an output format is given to "git commit", we
default to "--dry-run". This behavior would now kick in
when "--long" is given, too.

branch: skip commit checks when deleting symref branches
Before a branch is deleted, we check that it points to a valid
commit. With -d we also check that the commit is a merged; this
check is not done with -D.
The reason for that is that commits pointed to by branches should
never go missing; if they do then something broke and it's better
to stop instead of adding to the mess. And a non-merged commit
may contain changes that are worth preserving, so we require the
stronger option -D instead of -d to get rid of them.
If a branch consists of a symref, these concerns don't apply.
Deleting such a branch can't make a commit become unreferenced,
so we don't need to check if it is merged, or even if it is
actually a valid commit. Skip them in that case. This allows
us to delete dangling symref branches.

format-patch tests: check quoting/encoding in To: and Cc: headers
git-format-patch does currently not parse user supplied extra header
values (e. g., --cc, --add-header) and just replays them. That forces
users to add them RFC 2822/2047 conform in encoded form, e.g.
which is inconvenient. We would want to update git-format-patch to
accept human-readable input
--cc 'Jan H. Schönherr <...>'
and handle the encoding, wrapping and quoting internally in the future,
similar to what is already done in git-send-email. The necessary code
should mostly exist in the code paths that handle the From: and Subject:
headers.
Whether we want to do this only for the git-format-patch options
--to and --cc (and the corresponding config options) or also for
user supplied headers via --add-header, is open for discussion.
For now, add test_expect_failure tests for To: and Cc: headers as a

implemented.

The wrapping logic in strbuf_add_wrapped_text() does currently not allow
lines that entirely fill the allowed width, instead it wraps the line one
character too early.
For example, the text "This is the sixth commit." formatted via
"%w(11,1,2)" (wrap at 11 characters, 1 char indent of first line, 2 char
indent of following lines) results in four lines: " This is", " the",
" sixth", " commit." This is wrong, because " the sixth" is exactly
11 characters long, and thus allowed.
Fix this by allowing the (width+1) character of a line to be a valid
wrapping point if it is a whitespace character.

strbuf: always return a non-NULL value from strbuf_detach
The current behavior is to return NULL when strbuf did not
actually allocate a string. This can be quite surprising to
callers, though, who may feed the strbuf from arbitrary data
and expect to always get a valid value.
In most cases, it does not make a difference because calling
any strbuf function will cause an allocation (even if the
function ends up not inserting any data). But if the code is
structured like:
then you may or may not return NULL, depending on the
condition. This can cause us to segfault in http-push
(when fed an empty URL) and in http-backend (when an empty
parameter like "foo=bar&&" is in the $QUERY_STRING).
This patch forces strbuf_detach to allocate an empty
NUL-terminated string when it is called on a strbuf that has
not been allocated.
I investigated all call-sites of strbuf_detach. The majority
are either not affected by the change (because they call a
strbuf_* function unconditionally), or can handle the empty
string just as easily as NULL.

format-patch --notes: show notes after three-dashes
When inserting the note after the commit log message to format-patch
output, add three dashes before the note. Record the fact that we
did so in the rev_info and omit showing duplicated three dashes in
the usual codepath that is used when notes are not being shown.
When appending a new signature with "format-patch --signature", if
the "--notes" option is also in effect, the location of the new
signature (and if the signature should be added in the first place)
should be decided using the contents of the original commit log
message, before the message from the notes is added.
pretty_print_commit(): do not append notes message
The only case pretty_print_commit() appends notes message to the log
message taken from the commit is when show_log() calls it with the
notes_message field set, and the output format is not the userformat
(i.e. when substituting "%N"). No other users of this function sets
this field in the pretty_print_context, as can be easily verified in
the previous step.
Hoist the code to append the notes message to the caller.
Up to this point, no functionality change is intended.
We either stuff the notes message without modification for %N
userformat, or format it for human consumption. Using two bits
is an overkill that does not benefit anybody.
This function has only two callsites, and is a thin wrapper whose
usefulness is dubious. When the caller needs to learn the log
output encoding, it should be able to do so by directly calling
get_log_output_encoding() and calling the underlying
logmsg_reencode() with it.

When we get an http 401, we prompt for credentials and put
them in our global credential struct. We also feed them to
the curl handle that produced the 401, with the intent that
they will be used on a retry.
When the code was originally introduced in commit 42653c0,
this was a necessary step. However, since dfa1725, we always
feed our global credential into every curl handle when we
initialize the slot with get_active_slot. So every further
request already feeds the credential to curl.
Moreover, accessing the slot here is somewhat dubious. After
the slot has produced a response, we don't actually control
it any more. If we are using curl_multi, it may even have
been re-initialized to handle a different request.
It just so happens that we will reuse the curl handle within
the slot in such a case, and that because we only keep one
global credential, it will be the one we want. So the
current code is not buggy, but it is misleading.
By cleaning it up, we can remove the slot argument entirely
from handle_curl_result, making it much more obvious that
slots should not be accessed after they are marked as
finished.

Commit b81401c (http: prompt for credentials on failed POST)
taught post_rpc to call run_slot in a loop in order to retry
a request after asking the user for credentials. However,
after a call to run_slot we will have called
finish_active_slot. This means we have released the slot,
and we should no longer look at it.
As it happens, this does not cause any bugs in the current
code, since we know that we are not using curl_multi in this
code path, and therefore nobody will have taken over our
slot in the meantime. However, it is good form to actually
call get_active_slot again. It also future proofs us against
changes in the http code.
We can do this by jumping back to a retry label at the top
of our function. We just need to reorder a few setup lines
that should not be repeated; everything else within the loop
is either idempotent, needs to be repeated, or in a path we
do not follow (e.g., we do not even try when large_request
is set, because we don't know how much data we might have
streamed from our helper program).

When we create an http active_request_slot, we can set its
"results" pointer back to local storage. The http code will
fill in the details of how the request went, and we can
access those details even after the slot has been cleaned
up.
Commit 8809703 (http: factor out http error code handling)
switched us from accessing our local results struct directly
to accessing it via the "results" pointer of the slot. That
means we're accessing the slot after it has been marked as
finished, defeating the whole purpose of keeping the results
storage separate.
Most of the time this doesn't matter, as finishing the slot
does not actually clean up the pointer. However, when using
curl's multi interface with the dumb-http revision walker,
we might actually start a new request before handing control
back to the original caller. In that case, we may reuse the
slot, zeroing its results pointer, and leading the original
caller to segfault while looking for its results inside the
slot.
Instead, we need to pass a pointer to our local results
storage to the handle_curl_result function, rather than
relying on the pointer in the slot struct. This matches what
the original code did before the refactoring (which did not
use a separate function, and therefore just accessed the
results struct directly).

instead of "path".
This patch passes real paths down to grep_source_load_driver() when:
- grep on work tree
- grep on the index
- grep a commit (or a tag if it points to a commit)
so that these cases look up .gitattributes at proper paths.
.gitattributes lookup is disabled in all other cases.
