When make is run, the python scripts are created from *.py files that
are changed to use the python given by PYTHON_PATH. And PYTHON_PATH
is set by default to /usr/bin/python on Linux.
This is nice except when you run make another time setting a
different PYTHON_PATH, because, as the python scripts have already
been created, make finds nothing to do.
The goal of this patch is to detect when the PYTHON_PATH changes and
to create the python scripts again when this happens. To do that we
use the same trick that is done to track other variables like prefix,
flags, tcl/tk path and shell path. We update a GIT-PYTHON-VARS file
with the PYTHON_PATH and check if it changed.

Intent-to-add entries used to forbid writing trees so it was not a
problem. After commit 3f6d56d (commit: ignore intent-to-add entries

However, the commit forgets to invalidate all paths leading to i-t-a
entries. With fully valid cache-tree (e.g. after commit or
write-tree), diff operations may prefer cache-tree to index and not
see i-t-a entries in the index, because cache-tree does not have them.

entry_count is used in update_one() for two purposes:

2. to record the number of entries this cache-tree covers on disk
Unfortunately when CE_REMOVE is present these numbers are not the same
because CE_REMOVE entries are automatically removed before writing to
disk but entry_count is not adjusted and still counts CE_REMOVE
entries.

There are a few error functions that simply wrap error() and
provide a standardized message text. Like error(), they
always return -1; knowing that can help the compiler silence
some false positive -Wuninitialized warnings.
One strategy would be to just declare these as inline in the
header file so that the compiler can see that they always
return -1. However, gcc does not always inline them (e.g.,
it will not inline opterror, even with -O3), which renders
our change pointless.
Instead, let's follow the same route we did with error() in
the last patch, and define a macro that makes the constant
return value obvious to the compiler.
Signed-off-by: Jeff King <peff@peff.net>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
When git is compiled with "gcc -Wuninitialized -O3", some
inlined calls provide an additional opportunity for the
compiler to do static analysis on variable initialization.
For example, with two functions like this:
int get_foo(int *foo)
{
if (something_that_might_fail() < 0)
return error("unable to get foo");
*foo = 0;
return 0;
}
void some_fun(void)
{
int foo;
if (get_foo(&foo) < 0)
return -1;
printf("foo is %d\n", foo);
}
If get_foo() is not inlined, then when compiling some_fun,
gcc sees only that a pointer to the local variable is
passed, and must assume that it is an out parameter that
is initialized after get_foo returns.
However, when get_foo() is inlined, the compiler may look at
all of the code together and see that some code paths in
get_foo() do not initialize the variable. As a result, it
prints a warning. But what the compiler can't see is that
error() always returns -1, and therefore we know that either
we return early from some_fun, or foo ends up initialized,
and the code is safe. The warning is a false positive.
If we can make the compiler aware that error() will always
return -1, it can do a better job of analysis. The simplest
method would be to inline the error() function. However,
this doesn't work, because gcc will not inline a variadc
function. We can work around this by defining a macro. This
relies on two gcc extensions:
1. Variadic macros (these are present in C99, but we do
not rely on that).
2. Gcc treats the "##" paste operator specially between a
comma and __VA_ARGS__, which lets our variadic macro
work even if no format parameters are passed to
error().
Since we are using these extra features, we hide the macro
behind an #ifdef. This is OK, though, because our goal was
just to help gcc.

In remote-test-svn, there is a parse_rev_note function to
parse lines of the form "Revision-number" from notes. If it
finds such a line and parses it, it returns 0, copying the
value into a "struct rev_note". If it finds an entry that is
garbled or out of range, it returns -1 to signal an error.
However, if it does not find any "Revision-number" line at
all, it returns success but does not put anything into the
rev_note. So upon a successful return, the rev_note may or
may not be initialized, and the caller has no way of
knowing.
gcc does not usually catch the use of the unitialized
variable because the conditional assignment happens in a
separate function from the point of use. However, when
compiling with -O3, gcc will inline parse_rev_note and
notice the problem.
We can fix it by returning "-1" when no note is found (so on
a zero return, we always found a valid value).

The motivation for mailmap.blob is to let users of bare
repositories use the mailmap feature, as they would not have
a checkout containing the .mailmap file. We can make it even
easier for them by just looking in HEAD:.mailmap by default.
We can't know for sure that this is where they would keep a
mailmap, of course, but it is the best guess (and it matches
the non-bare behavior, which reads from HEAD:.mailmap in the
working tree). If it's missing, git will silently ignore the
setting.
We do not do the same magic in the non-bare case, because:
1. In the common case, HEAD:.mailmap will be the same as
the .mailmap in the working tree, which is a no-op.
2. In the uncommon case, the user has modified .mailmap
but not yet committed it, and would expect the working
tree version to take precedence.

A cache-tree entry with a negative entry count is considered invalid
by the current Git; it records that we do not know the object name
of a tree that would result by writing the directory covered by the
cache-tree as a tree object.
Clarify that any entry with a negative entry count is invalid, but
the implementations must write -1 there. This way, we can later
decide to allow writers to use negative values other than -1 to
encode optional information on such invalidated entries without
harming interoperability; we do not know what will be encoded and
how, so we keep these other negative values as reserved for now.

The error handling for the read_mailmap function is odd. It
returns 1 on error, rather than -1. And it treats a
non-existent mailmap as an error, even though there is no
reason that one needs to exist. Unless some other mailmap
source loads successfully, in which case the original error
is completely masked.
This does not cause any bugs, however, because no caller
bothers to check the return value, anyway. Let's make this a
little more robust to real errors and less surprising for
future callers that do check the error code:
1. Return -1 on errors.
2. Treat a missing entry (e.g., no mailmap.file given),
ENOENT, or a non-existent blob (for mailmap.blob) as
"no error".
3. Complain loudly when a real error (e.g., a transient
I/O error, no permission to open the mailmap file,
missing or corrupted blob object, etc) occurs.
