The whitespace error of adding blank lines at the end of file should
trigger if you added a non-empty line at the end, if the contents of the
line is full of whitespaces.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
"git apply" strips new blank lines at EOF under --whitespace=fix option,
but neigher --whitespace=warn nor --whitespace=error paid any attention to
these errors.
Introduce a new whitespace error class, blank-at-eof, to make the
whitespace error handling more consistent.
The patch adds a new "linenr" field to the struct fragment in order to
record which line the hunk started in the input file, but this is needed
solely for reporting purposes. The detection of this class of whitespace
errors cannot be done while parsing a patch like we do for all the other
classes of whitespace errors. It instead has to wait until we find where
to apply the hunk, but at that point, we do not have an access to the
original line number in the input file anymore, hence the new field.
Depending on your point of view, this may be a bugfix that makes warn and
error in line with fix. Or you could call it a new feature. The line
between them is somewhat fuzzy in this case.
Strictly speaking, triggering more errors than before is a change in
behaviour that is not backward compatible, even though the reason for the
change is because the code was not checking for an error that it should
have. People who do not want added blank lines at EOF to trigger an error
can disable the new error class.

This splits the logic to record the presence of whitespace errors out of
the check_whitespace() function, which checks and then records. The new
function, record_ws_error(), can be used by the blank-at-eof check that
does not use ws_check() logic to report its findings in the same output
format.

The command tries to strip blank lines at the end of the file added by a
patch. It is done by first detecting if a hunk in patch has additional
blank lines at the end of itself, and if so checking if such a hunk
applies at the end of file. This patch addresses a bug in the logic to
implement the former (the previous one addressed a bug in the latter).
If the original ends with blank lines, often the patch hunk ends like
this:
@@ -l,5 +m,7 @@$
_context$
_context$
-deleted$
+$
+$
+$
_$
_$
where _ stands for SP and $ shows a end-of-line. This example patch adds
three trailing blank lines, but the code fails to notice it, because it
only pays attention to added blank lines at the very end of the hunk. In
this example, the three added blank lines do not appear textually at the
end in the patch, even though you can see that they are indeed added at
the end, if you rearrange the diff like this:
@@ -l,5 +m,7 @@$
_context$
_context$
-deleted$
_$
_$
+$
+$
+$
The fix is not to reset the number of (candidate) added blank lines at the
end when the loop sees a context line that is empty.

b94f2ed (builtin-apply.c: make it more line oriented, 2008-01-26) broke
the logic used to detect if a hunk adds blank lines at the end of the
file. With the new code after that commit:
- img holds the contents of the file that the hunk is being applied to;
- preimage has the lines the hunk expects to be in img; and
- postimage has the lines the hunk wants to update the part in img that
corresponds to preimage with.
and we need to compare if the last line of preimage (not postimage)
matches the last line of img to see if the hunk applies at the end of the
file.

When making a histogram of delta chain length in the pack, the program
collects number of objects whose delta depth exceeds the MAX_CHAIN limit
in histogram[0], and showed it as the number of items that exceeds the
limit correctly. HOWEVER, it also showed the same number labeled as
"chain length = 0".
In fact, we are not showing the number of objects whose chain length is
zero, i.e. the base objects. Correct this.

When interpreting a config value, the config parser reads in 1+ space
character(s) and puts -one- space character in the buffer as soon as
the first non-space character is encountered (if not inside quotes).
Unfortunately the buffer size check lacks the extra space character
which gets inserted at the next non-space character, resulting in
a crash with a specially crafted config entry.
The unit test now uses Java to compile a platform independent
.NET framework to output the test string in C# :o)

Ack, ack.
There's another easy 5% or so for the built-in object walker: once we've
created the hash from the name, the name isn't interesting any more, and
so something trivial like this can help a bit.
Does it matter? Probably not on its own. But a few more memory saving
tricks and it might all make a difference.

The name of the processed object was duplicated for passing it to

On a 32-bit system, the maximum possible size for an object is less than
4GB, while 64-bit systems may cope with larger objects. Due to this
limitation, variables holding object sizes are using an unsigned long
type (32 bits on 32-bit systems, or 64 bits on 64-bit systems).
When large objects are encountered, and/or people play with large delta
depth values, it is possible for the maximum allowed delta size
computation to overflow, especially on a 32-bit system. When this
occurs, surviving result bits may represent a value much smaller than
what it is supposed to be, or even zero. This prevents some objects
from being deltified although they do get deltified when a smaller depth
limit is used. Fix this by always performing a 64-bit multiplication.

When there is nothing to be skipped, the output from
rev-list --bisect-vars was eval'ed without first being
strung together with &&; this is probably not a problem

When the "bad" commit was also "skip"ped and when more than one
commit was skipped, the "filter_skipped" function would have
printed something like:
bisect_rev=<hash1>|<hash2>
(where <hash1> and <hash2> are hexadecimal sha1 hashes)
and this would have been evaled later as piping "bisect_rev=<hash1>"
into "<hash2>", which would have failed.
So this patch makes the "filter_skipped" function properly quote
what it outputs, so that it will print something like:
bisect_rev='<hash1>|<hash2>'
which will be properly evaled later. The caller was not stopping
properly because the scriptlet this function returned to be evaled
was not strung together with && and because of this, an error in
an earlier part of the output was simply ignored.
A test case is added to the test suite.
And while at it, we also initialize the VARS, FOUND and TRIED
variables, so that we protect ourselves from environment variables
the user may have with these names.
