The "action" parameters for these two tests were supplied incorrectly for
the way the tests were implemented. The tests check whether a program
which calls hstrerror() or basename() successfully links when -lresolv or
-lgen are used, respectively. A successful linking would result in
NEEDS_RESOLV or NEEDS_LIBGEN being unset, and failure would result in
setting the respective variable.
Aside from that issue, the tests did not handle the case where neither
library was necessary for accessing the functions in question. So solve
both of these issues by re-working the two tests so that their form is like
the NEEDS_SOCKET test which attempts to link with just the c library, and
if it fails then assumes that the additional library is necessary and sets
the appropriate variable.
Also an entry in the config.mak.in file is necessary for the NEEDS_LIBGEN
variable to appear in the config.mak.autogen file with the value assigned
by the configure script. Without it, the generated shell script would
contain a snippet like this:
for ac_lib in ; do
...
which is incorrect.

Trailing whitespace and no newline fix
diff --cc: a lost line at the beginning of the file is shown incorrectly
combine-diff.c: fix performance problem when folding common deleted lines
|
|
If a patch adds a new line to the end of a file and this line ends with
one trailing whitespace character and has no newline, then
'--whitespace=fix' currently does not remove that trailing whitespace.
This patch fixes this by removing the check for trailing whitespace at
the end of the line at a hardcoded offset which does not take the
eventual absence of newline into account.

When combine-diff inspected the diff from one parent to the merge result,
it misinterpreted a header in the form @@ -l,k +0,0 @@.
This hunk header means that K lines were removed from the beginning of the
file, so the lost lines must be queued to the sline that represents the
first line of the merge result, but we incremented our pointer incorrectly
and ended up queuing it to the second line, which in turn made the lossage
appear _after_ the first line.

While reading the second patch (that removes "two" and then "fyra"), after
finding where removal of the "two" matches, we need to find existing
removal of "fyra" (if exists) in the removal list, but the match has to
happen after all the existing matches (in this case "two"). The code used
a naïve O(n^2) algorithm to compute this by scanning the whole removal
list over and over again.
This patch remembers where the next scan should be started in the existing
removal list to avoid this.

checkout -f: deal with a D/F conflict entry correctly
sha1_name.c: avoid unnecessary strbuf_release
refs.c: release file descriptor on error return
|
|
When we switch branches with "checkout -f", unpack_trees() feeds two
cache_entries to oneway_merge() function in its src[] array argument. The
zeroth entry comes from the current index, and the first entry represents
what the merge result should be, taken from the tree recorded in the
commit we are switching to.
When we have a blob (either regular file or a symlink) in the index and in
the work tree at path "foo", and the switched-to tree has "foo/bar",
i.e. "foo" becomes a directory, src[0] is obviously that blob currently
registered at "foo". Even though we do not have anything at "foo" in the
switched-to tree, src[1] is _not_ NULL in this case.
The unpack_trees() machinery places a special marker df_conflict_entry
to signal that no blob exists at "foo", but it will become a directory
that may have somthing underneath it (namely "foo/bar"), so a usual 3-way
merge can notice the situation.
But oneway_merge() codepath failed to notice this and passed the special
marker directly to merged_entry(). This happens to remove the "foo" in
the end because the df_conflict_entry does not have any name (hence the
"error" message) and its addition in add_index_entry() is rejected, but it
is wrong.

When we fall back to a standard for_each_reflog_ent() after failing to find
the nth branch switch (or if we had a short reflog) with the call to
for_each_recent_reflog_ent(), we do not need to free the memory allocated
for our strbuf's since a strbuf_reset() will be performed in
grab_nth_branch_switch() before assigning to the entry.
Plus, the strbuf_release() negates the non-zero hint we initially gave to
strbuf_init() just above these lines.

This reverts commit 650d30d8a120c8982309ccb9ef40432b4ea2eb74.
Some mailing lists are configured add prefix "[listname] " to all their
messages, and also people hand-edit subject lines, be it an output from
format-patch or a patch generated by some other means.
We cannot stop people from mucking with the subject line, and with the
change, there always will be need for hand editing the subject when that
happens. People have depended on the leading [bracketed string] removal.

In our 'oneway_merge()' we always do an 'lstat()' to see if we might
need to mark the entry for updating.
But we really shouldn't need to do that when the cache entry is already
marked as being ce_uptodate(), and this makes us do unnecessary lstat()
calls if we have index preloading enabled.

Not that anybody should ever get it, but somebody did (probably because
of a flaky filesystem, but whatever). And each time I see an error
message that I haven't seen before, I decide that next time it will look
better.
So this makes us write more relevant information about exactly which
file ended up having issues with a missing object. Which will tell
whether it was a tree object, for example, or just a regular file in the
index (and which one).

For some reason, I ended up doing
git show HEAD~5..
as an odd way of asking for a log. I realize I should just have used "git
log", but at the same time it does make perfect conceptual sense. After
all, you _could_ have done
git show HEAD HEAD~1 HEAD~2 HEAD~3 HEAD~4
and saying "git show HEAD~5.." is pretty natural. It's not like "git show"
only ever showed a single commit (or other object) before either! So
conceptually, giving a commit range is a very sensible operation, even
though you'd traditionally have used "git log" for that.
However, doing that currently results in an error
fatal: object ranges do not make sense when not walking revisions
which admittedly _also_ makes perfect sense - from an internal git
implementation standpoint in 'revision.c'.
However, I think that asking to show a range makes sense to a user, while
saying "object ranges no not make sense when not walking revisions" only
makes sense to a git developer.
So on the whole, of the two different "makes perfect sense" behaviors, I
think I originally picked the wrong one. And quite frankly, I don't really
see anybody actually _depending_ on that error case. So why not change it?
So rather than error out, just turn that non-walking error case into a
"silently turn on walking" instead.

For the case of multiple projects sharing a single SVN repository, it is
common practice to create the standard SVN directory layout within a
subdirectory for each project. In such setups, access control is often
used to limit what projects a given user may access. git-svn failed to
detect branches (e.g. when passing --stdlayout to clone) because it
relied on having access to the root directory in the repository. This
patch solves this problem by making git-svn use paths relative to the
given repository URL instead of the repository root.

quickfetch() calls rev-list to check whether the objects we are about to
fetch are already present in the repo (if so, we can skip the object fetch).
However, when there are many (~1000) refs to be fetched, the rev-list
command line grows larger than the maximum command line size on some systems
(32K in Windows). This causes rev-list to fail, making quickfetch() return
non-zero, which unnecessarily triggers the transport machinery. This somehow
causes fetch to fail with an exit code.
By using the --stdin option to rev-list (and feeding the object list to its
standard input), we prevent the overflow of the rev-list command line,
which causes quickfetch(), and subsequently the overall fetch, to succeed.
However, using rev-list --stdin is not entirely straightforward: rev-list
terminates immediately when encountering an unknown object, which can
trigger SIGPIPE if we are still writing object's to its standard input.
We therefore temporarily ignore SIGPIPE so that the fetch process is not
terminated.
The patch also contains a testcase to verify the fix (note that before
the patch, the testcase would only fail on msysGit).

Don't define _XOPEN_SOURCE
Do define _SGI_SOURCE
Defining _XOPEN_SOURCE prevents many of the common functions and macros
from being defined. _Not_ setting _XOPEN_SOURCE, and instead setting
_SGI_SOURCE, provides all of the XPG4, XPG5, BSD, POSIX functions and
declarations, _BUT_ provides a horribly broken snprintf(). SGI does have
a working snprintf(), but it is only provided when _NO_XOPEN5 evaluates
to zero, and this only happens if _XOPEN_SOURCE is defined which, as
mentioned above, prevents many other common functions and defines.
The broken snprintf will be worked around with SNPRINTF_RETURNS_BOGUS in
the Makefile in a later patch.

The c99 MIPSpro Compiler version 7.4.4m on IRIX 6.5 does not properly
initialize run-time initialized arrays. An array which is initialized with
fewer elements than the length of the array should have the unitialized
elements initialized to zero. This compiler only initializes the remaining
elements when the last element is a static parameter. So work around it
by adding a "NULL" initialization parameter.

This uses the new thread-safe 'threaded_has_symlink_leading_path()'
function to efficiently verify that the whole path leading up to the
filename is a proper path, and does not contain symlinks.
This makes 'ce_uptodate()' a much stronger guarantee: it no longer just
guarantees that the 'lstat()' of the path would match, it also means
that we know that people haven't played games with moving directories
around and covered it up with symlinks.

When a git command executes a subcommand, it uses the "git
foo" form, which relies on finding "git" in the PATH.
Normally this should not be a problem, since the same "git"
that was used to invoke git in the first place will be
found. And if somebody invokes a "git" outside of the PATH
(e.g., by giving its absolute path), this case is already
covered: we put that absolute path onto the front of PATH.
However, if one is using "sudo", then sudo will execute the
"git" from the PATH, but pass along a restricted PATH that
may not contain the original "git" directory. In this case,
executing a subcommand will fail.
To solve this, we put the "git" wrapper itself into the
execdir; this directory is prepended to the PATH when git
starts, so the wrapper will always be found.

Most of the users of "read_directory()" actually want a much simpler
interface than the whole complex (but rather powerful) one.
In fact 'git add' had already largely abstracted out the core interface
issues into a private "fill_directory()" function that was largely
applicable almost as-is to a number of callers. Yes, 'git add' wants to
do some extra work of its own, specific to the add semantics, but we can
easily split that out, and use the core as a generic function.
This function does exactly that, and now that much simplified
'fill_directory()' function can be shared with a number of callers,
while also ensuring that the rather more complex calling conventions of
read_directory() are used by fewer call-sites.
This also makes the 'common_prefix()' helper function private to dir.c,
since all callers are now in that file.
