Commit 1bbcc224 ("http: refactor options to http_get_*", 28-09-2013)
changed the type of final 'options' argument of the http_get_file()
function from an int to an 'struct http_get_options' pointer.
However, it neglected to update the (single) call site. Since this
call was passing '0' to that argument, it was (correctly) being
interpreted as a null pointer. Change to argument to NULL.
Noticed by sparse. ("Using plain integer as NULL pointer")

For efficiency and security reasons, an earlier commit in
this series taught http_get_* to re-write the base url based
on redirections we saw while making a specific request.
This commit wires that option into the info/refs request,
meaning that a redirect from
http://example.com/foo.git/info/refs
to
https://example.com/bar.git/info/refs
will behave as if "https://example.com/bar.git" had been
provided to git in the first place.
The tests bear some explanation. We introduce two new
hierearchies into the httpd test config:
1. Requests to /smart-redir-limited will work only for the
initial info/refs request, but not any subsequent
requests. As a result, we can confirm whether the
client is re-rooting its requests after the initial
contact, since otherwise it will fail (it will ask for
"repo.git/git-upload-pack", which is not redirected).
2. Requests to smart-redir-auth will redirect, and require
auth after the redirection. Since we are using the
redirected base for further requests, we also update
the credential struct, in order not to mislead the user
(or credential helpers) about which credential is
needed. We can therefore check the GIT_ASKPASS prompts
to make sure we are prompting for the new location.
Because we have neither multiple servers nor https
support in our test setup, we can only redirect between
paths, meaning we need to turn on
credential.useHttpPath to see the difference.

We use a strbuf to generate the string containing the remote
URL, but then detach it to a bare pointer. This makes it
harder to later manipulate the URL, as we have forgotten the
length (and the allocation semantics are not as clear).
Let's instead keep the strbuf around. As a bonus, this
eliminates a confusing double-use of the "buf" strbuf in
main(). Prior to this, it was used both for constructing the
url, and for reading commands from stdin.
The downside is that we have to update each call site to
refer to "url.buf" rather than just "url" when they want the
C string.

In the discover_refs function, we use a strbuf named
"buffer" for multiple purposes. First we build the info/refs
URL in it, and then detach that to a bare pointer. Then, we
use the same strbuf to store the result of fetching the
refs.
Let's instead keep a separate refs_url strbuf. This is less
confusing, as the "buffer" strbuf is now used for only one
thing.

If a caller asks the http_get_* functions to go to a
particular URL and we end up elsewhere due to a redirect,
the effective_url field can tell us where we went.
It would be nice to remember this redirect and short-cut
further requests for two reasons:
1. It's more efficient. Otherwise we spend an extra http
round-trip to the server for each subsequent request,
just to get redirected.
2. If we end up with an http 401 and are going to ask for
credentials, it is to feed them to the redirect target.
If the redirect is an http->https upgrade, this means
our credentials may be provided on the http leg, just
to end up redirected to https. And if the redirect
crosses server boundaries, then curl will drop the
credentials entirely as it follows the redirect.
However, it, it is not enough to simply record the effective
URL we saw and use that for subsequent requests. We were
originally fed a "base" url like:
http://example.com/foo.git
and we want to figure out what the new base is, even though
the URLs we see may be:
original: http://example.com/foo.git/info/refs
effective: http://example.com/bar.git/info/refs
Subsequent requests will not be for "info/refs", but for
other paths relative to the base. We must ask the caller to
pass in the original base, and we must pass the redirected
base back to the caller (so that it can generate more URLs
from it). Furthermore, we need to feed the new base to the
credential code, so that requests to credential helpers (or
to the user) match the URL we will be requesting.
This patch teaches http_request_reauth to do this munging.
Since it is the caller who cares about making more URLs, it
seems at first glance that callers could simply check
effective_url themselves and handle it. However, since we
need to update the credential struct before the second
re-auth request, we have to do it inside http_request_reauth.

When we ask curl to access a URL, it may follow one or more
redirects to reach the final location. We have no idea
this has happened, as curl takes care of the details and
simply returns the final content to us.
The final URL that we ended up with can be accessed via
CURLINFO_EFFECTIVE_URL. Let's make that optionally available
to callers of http_get_*, so that they can make further
decisions based on the redirection.

When we are handling a curl response code in http_request or
in the remote-curl RPC code, we use the handle_curl_result
helper to translate curl's response into an easy-to-use
code. When we see an HTTP 401, we do one of two things:
1. If we already had a filled-in credential, we mark it as
rejected, and then return HTTP_NOAUTH to indicate to
the caller that we failed.
2. If we didn't, then we ask for a new credential and tell
the caller HTTP_REAUTH to indicate that they may want
to try again.
Rejecting in the first case makes sense; it is the natural
result of the request we just made. However, prompting for
more credentials in the second step does not always make
sense. We do not know for sure that the caller is going to
make a second request, and nor are we sure that it will be
to the same URL. Logically, the prompt belongs not to the
request we just finished, but to the request we are (maybe)
about to make.
In practice, it is very hard to trigger any bad behavior.
Currently, if we make a second request, it will always be to
the same URL (even in the face of redirects, because curl
handles the redirects internally). And we almost always
retry on HTTP_REAUTH these days. The one exception is if we
are streaming a large RPC request to the server (e.g., a
pushed packfile), in which case we cannot restart. It's
extremely unlikely to see a 401 response at this stage,
though, as we would typically have seen it when we sent a
probe request, before streaming the data.
This patch drops the automatic prompt out of case 2, and
instead requires the caller to do it. This is a few extra
lines of code, and the bug it fixes is unlikely to come up
in practice. But it is conceptually cleaner, and paves the
way for better handling of credentials across redirects.

Over time, the http_get_strbuf function has grown several
optional parameters. We now have a bitfield with multiple
boolean options, as well as an optional strbuf for returning
the content-type of the response. And a future patch in this
series is going to add another strbuf option.
Treating these as separate arguments has a few downsides:
1. Most call sites need to add extra NULLs and 0s for the
options they aren't interested in.
2. The http_get_* functions are actually wrappers around
2 layers of low-level implementation functions. We have
to pass these options through individually.
3. The http_get_strbuf wrapper learned these options, but
nobody bothered to do so for http_get_file, even though
it is backed by the same function that does understand
the options.
Let's consolidate the options into a single struct. For the
common case of the default options, we'll allow callers to
simply pass a NULL for the options struct.
The resulting code is often a few lines longer, but it ends
up being easier to read (and to change as we add new
options, since we do not need to update each call site).

When we retrieve the content-type of an http response, curl
gives us a pointer to internal storage, which we then copy
into a strbuf. Let's factor out the get-and-copy routine,
which can be used for getting other curl info.

Since a1549e10, git-rebase--am.sh uses the shell's "return" statement, to
mean "return from the current file inclusion", which is POSIXly correct,
but badly interpreted on FreeBSD, which returns from the current
function, hence skips the finish_rebase statement that follows the file
inclusion.
Make the use of "return" portable by using the file inclusion as the last
statement of a function.

When the temp_is_locked function was introduced, there was
a desire to make _temp_cache use it. Unfortunately due to the
various tests and logic flow involved changing the _temp_cache
function to use the new temp_is_locked function is problematic
as _temp_cache needs a slightly different test than is provided
by the temp_is_locked function.
This change reverts use of temp_is_locked in the _temp_cache
function and restores the original code that existed there
before the temp_is_locked function was added.

When attempting to git-svn fetch files from an svn https?: url using
the serf library (the only choice starting with svn 1.8) the following
errors can occur:
Temp file with moniker 'svn_delta' already in use at Git.pm line 1250
Temp file with moniker 'git_blob' already in use at Git.pm line 1250
David Rothenberger <daveroth@acm.org> has determined the cause to
be that ra_serf does not drive the delta editor in a depth-first
manner [...]. Instead, the calls come in this order:
1. open_root
2. open_directory
3. add_file
4. apply_textdelta
5. add_file
6. apply_textdelta
When using the ra_serf access method, git-svn can end up needing
to create several temp files before the first one is closed.
This change causes a new temp file moniker to be generated if the
one that would otherwise have been used is currently locked.

Mediawiki introduces a new API for queries w/ more than 500 results in
version 1.21. That change triggered an infinite loop while cloning a
mediawiki with such a page.
The latest API renamed and moved the "continuing" information in the
response, necessary to build the next query. The code failed to retrieve
that information but still detected that it was in a "continuing
query". As a result, it launched the same query over and over again.
If a "continuing" information is detected in the response (old or new),
the next query is updated accordingly. If not, we quit assuming it's not
a continuing query.

As suggested by Junio, let's test whether printf supports the -v

determine whether 'printf -v' can be used, or whether printf
must be called in a subshell.

This triggered at least one bug: the error message of "rebase -i" was
turning \t in commit messages into actual tabulations. There may be
others.
Using "printf '%s\n'" instead avoids this bad behavior, and is the form
used by the "say" function.

Here is an example .gitmodules that will cause a segmentation fault:

Segmentation fault (core dumped)
This is because the parsing of "submodule.*.path" is not prepared to
see a value-less "true" and assumes that the value is always
non-NULL (parsing of "ignore" has the same problem).
Fix it by checking the NULL-ness of value and complain with

The reflog walking logic (git log -g) replaces the true parent list
with the preceding commit in the reflog. This results in bogus commit
diffs when combined with options such as -p; the diff is against the
reflog predecessor, not the parent of the commit.
Save the true parents on the side, extending the functions from the
previous commit. The diff logic picks them up and uses them to show
the correct diffs.
We do have to be somewhat careful about repeated calling of
save_parents(), since the reflog may list a commit more than once. We
now store (commit_list*)-1 to distinguish the "not saved yet" and
"root commit" cases. This lets us preserve an empty parent list even

When using pathspec filtering in combination with diff-based log
output, parent simplification happens before the diff is computed.
The diff is therefore against the *simplified* parents.
This works okay, arguably by accident, in the normal case:
simplification reduces to one parent as long as the commit is TREESAME
to it. So the simplified parent of any given commit must have the
same tree contents on the filtered paths as its true (unfiltered)
parent.
However, --full-diff breaks this guarantee, and indeed gives pretty
spectacular results when comparing the output of
git log --graph --stat ...
git log --graph --full-diff --stat ...
(--graph internally kicks in parent simplification, much like
--parents).
To fix it, store a copy of the parent list before simplification (in a
slab) whenever --full-diff is in effect. Then use the stored parents
instead of the simplified ones in the commit display code paths. The
latter do not actually check for --full-diff to avoid duplicated code;
they just grab the original parents if save_parents() has not been
called for this revision walk.
For ordinary commits it should be obvious that this is the right thing
to do.
Merge commits are a bit subtle. Observe that with default
simplification, merge simplification is an all-or-nothing decision:
either the merge is TREESAME to one parent and disappears, or it is
different from all parents and the parent list remains intact.
Redundant parents are not pruned, so the existing code also shows them
as a merge.
So if we do show a merge commit, the parent list just consists of the
rewrite result on each parent. Running, e.g., --cc on this in
--full-diff mode is not very useful: if any commits were skipped, some
hunks will disagree with all sides of the merge (with one side,
because commits were skipped; with the others, because they didn't
have those changes in the first place). This triggers --cc showing
these hunks spuriously.
Therefore I believe that even for merge commits it is better to show
the diffs wrt. the original parents.

The auto-tag-following code in "git fetch" tries to reuse the same
transport twice when the serving end does not cooperate and does
not give tags that point to commits that are asked for as part of
the primary transfer. Unfortunately, Git-aware transport helper
interface is not designed to be used more than once, hence this
does not work over smart-http transfer.

A Git-aware "connect" transport allows the "transport_take_over" to
redirect generic transport requests like fetch(), push_refs() and
get_refs_list() to the native Git transport handling methods. The
take-over process replaces transport->data with a fake data that
these method implementations understand.
While this hack works OK for a single request, it breaks when the
transport needs to make more than one requests. transport->data
that used to hold necessary information for the specific helper to
work correctly is destroyed during the take-over process.
One codepath that this matters is "git fetch" in auto-follow mode;
when it does not get all the tags that ought to point at the history
it got (which can be determined by looking at the peeled tags in the
initial advertisement) from the primary transfer, it internally
makes a second request to complete the fetch. Because "take-over"
hack has already destroyed the data necessary to talk to the
transport helper by the time this happens, the second request cannot
make a request to the helper to make another connection to fetch
these additional tags.
Mark such a transport as "cannot_reuse", and use a separate
transport to perform the backfill fetch in order to work around
this breakage.
Note that this problem does not manifest itself when running t5802,
because our upload-pack gives you all the necessary auto-followed
tags during the primary transfer. You would need to step through
"git fetch" in a debugger, stop immediately after the primary
transfer finishes and writes these auto-followed tags, remove the
tag references and repack/prune the repository to convince the
"find-non-local-tags" procedure that the primary transfer failed to
give us all the necessary tags, and then let it continue, in order
to trigger the bug in the secondary transfer this patch fixes.

Usually the upload-pack process running on the other side will give
us all the reachable tags we need during the primary object transfer
in do_fetch(). If that does not happen (e.g. the other side may be
running a third-party implementation of upload-pack), we will run
another fetch to pick up leftover tags that we know point at the
commits reachable from our updated tips.
Separate out the code to run this second fetch into a helper
function.

Although many functions in this file take a "struct transport" as a
parameter, "fetch_one()" assigns to the global singleton instance
which is a file-scope static, in order to allow a parameterless
signal handler unlock_pack() to access it.
Rename the variable to gtransport to make sure these uses stand out.

This is an attempt to reproduce a problem reported for a third-party
custom "connect" remote helper. The conjecture is that sometimes
"git fetch" wants to make two connections (one for the primary
transfer with 'follow-tags' option set, and then after noticing that
some tags are not packed because the primary transfer did not have
to send any commit that is pointed by them, another to explicitly
ask for the missing tags), and their "connect" helper is not called
in the second request, breaking the "fetch" as a whole.
Unfortunately this test script does not trigger the alleged failure
and happily passes when talking to upload-pack from git-core (see
patch 5/5 for details).

Send a large request to read(2)/write(2) as a smaller but still

Checking out 2GB or more through an external filter (see test) fails
on Mac OS X 10.8.4 (12E55) for a 64-bit executable with:
error: read from external filter cat failed
error: cannot feed the input to external filter cat
error: cat died of signal 13
error: external filter cat failed 141
error: external filter cat failed
The reason is that read() immediately returns with EINVAL when asked
to read more than 2GB. According to POSIX [1], if the value of
nbyte passed to read() is greater than SSIZE_MAX, the result is
implementation-defined. The write function has the same restriction
[2]. Since OS X still supports running 32-bit executables, the
32-bit limit (SSIZE_MAX = INT_MAX = 2GB - 1) seems to be also
imposed on 64-bit executables under certain conditions. For write,
the problem has been addressed earlier [6c642a].
Address the problem for read() and write() differently, by limiting
size of IO chunks unconditionally on all platforms in xread() and
xwrite(). Large chunks only cause problems, like causing latencies
when killing the process, even if OS X was not buggy. Doing IO in
reasonably sized smaller chunks should have no negative impact on
performance.
The compat wrapper clipped_write() introduced earlier [6c642a] is
not needed anymore. It will be reverted in a separate commit. The
new test catches read and write problems.
Note that 'git add' exits with 0 even if it prints filtering errors
to stderr. The test, therefore, checks stderr. 'git add' should
probably be changed (sometime in another commit) to exit with
nonzero if filtering fails. The test could then be changed to use
test_must_fail.

The read_mailmap_buf function reads each line of the mailmap
using strchrnul, like:
const char *end = strchrnul(buf, '\n');
unsigned long linelen = end - buf + 1;
But that's off-by-one when we actually hit the NUL byte; our
line does not have a terminator, and so is only "end - buf"
bytes long. As a result, when we subtract the linelen from
the total len, we end up with (unsigned long)-1 bytes left
in the buffer, and we start reading random junk from memory.
We could fix it with:
unsigned long linelen = end - buf + !!*end;
but let's take a step back for a moment. It's questionable
in the first place for a function that takes a buffer and
length to be using strchrnul. But it works because we only
have one caller (and are only likely to ever have this one),
which is handing us data from read_sha1_file. Which means
that it's always NUL-terminated.
Instead of tightening the assumptions to make the
buffer/length pair work for a caller that doesn't actually
exist, let's let loosen the assumptions to what the real
caller has: a modifiable, NUL-terminated string.
This makes the code simpler and shorter (because we don't
have to correlate strchrnul with the length calculation),
correct (because the code with the off-by-one just goes
away), and more efficient (we can drop the extra allocation
we needed to create NUL-terminated strings for each line,
and just terminate in place).
