During the course of review for MyFirstContribution.txt, the suggestion
came up to include anchors to make it easier for veteran contributors to
link specific sections of this documents to newbies. To make life easier
for reviewers, add these anchors in their own commit. See review context
here: https://public-inbox.org/git/20190507195938.GD220818@google.com/
AsciiDoc does not support :sectanchors: and the anchors are not
discoverable, but they are referenceable. So a link to
"foo.com/MyFirstContribution.html#prerequisites" will still work if that
file was generated with AsciiDoc. The inclusion of :sectanchors: does
not create warnings or errors while compiling directly with `asciidoc -b
html5 Documentation/MyFirstContribution.txt` or while compiling with
`make doc`.
AsciiDoctor does support :sectanchors: and displays a paragraph link on
mouseover. When the anchor is included above or inline with a section
(as in this change), the link provided points to the custom ID contained
within [[]] instead of to an autogenerated ID. Practically speaking,
this means we have .../MyFirstContribution.html#summary instead of
.../MyFirstContribution.html#_summary. In addition to being prettier,
the custom IDs also enable anchor linking to work with
asciidoc-generated pages. This change compiles with no warnings using
`asciidoctor -b html5 Documentation/MyFirstContribution.txt`.

I fixed a bug that had broken the reading of sendmail.transferEncoding
in 3494dfd3ee ("send-email: do defaults -> config -> getopt in that
order", 2019-05-09), but the test I added in that commit did nothing
to assert the bug had been fixed.
That issue originates in 8d81408435 ("git-send-email: add
--transfer-encoding option", 2014-11-25) which first added the
"sendemail.transferencoding=8bit".
That test has never done anything meaningful. It tested that the
"--transfer-encoding=8bit" option would turn on the 8bit
Transfer-Encoding, but that was the default at the time (and now). As
checking out 8d81408435 and editing the test to remove that option
will reveal, supplying it never did anything.
So when I copied it thinking it would work in 3494dfd3ee I copied a
previously broken test, although I was making sure it did the right
thing via da-hoc debugger inspection, so the bug was fixed.
So fix the test I added in 3494dfd3ee, as well as the long-standing
test added in 8d81408435. To test if we're actually setting the
Transfer-Encoding let's set it to 7bit, not 8bit, as 7bit will error
out on "email-using-8bit".
This means that we can remove the "sendemail.transferencoding=7bit
fails on 8bit data" test, since it was redundant, we now have other
tests that assert that that'll fail.
While I'm at it convert "git config <key> <value>" in the test setup
to just "-c <key>=<value>" on the command-line. Then we don't need to
cleanup after these tests, and there's no sense in asserting where
config values come from in these tests, we can take that as a given.

Change our default CC_LD_DYNPATH invocation to something GCC likes
these days. Since the GCC 4.6 release unknown flags haven't been
passed through to ld(1). Thus our previous default of CC_LD_DYNPATH=-R
would cause an error on modern GCC unless NO_R_TO_GCC_LINKER was set.
This CC_LD_DYNPATH flag is really obscure, and I don't expect anyone
except those working on git development ever use this.
It's not needed to simply link to libraries like say libpcre,
but *only* for those cases where we're linking to such a library not
present in the OS's library directories. See e.g. ldconfig(8) on Linux
for more details.
I use this to compile my git with a LIBPCREDIR=$HOME/g/pcre2/inst as
I'm building that from source, but someone maintaining an OS package
is almost certainly not going to use this. They're just going to set
USE_LIBPCRE=YesPlease after installing the libpcre dependency,
which'll point to OS libraries which ld(1) will find without the help
of CC_LD_DYNPATH.
Another thing that helps mitigate any potential breakage is that we
detect the right type of invocation in configure.ac, which e.g. HP/UX
uses[1], as does IBM's AIX package[2]. From what I can tell both AIX
and Solaris packagers are building git with GCC, so I'm not adding a
corresponding config.mak.uname default to cater to their OS-native
linkers.
Now for an overview of past development in this area:
Our use of "-R" dates back to 455a7f3275 ("More portability.",
2005-09-30). Soon after that in bbfc63dd78 ("gcc does not necessarily
pass runtime libpath with -R", 2006-12-27) the NO_R_TO_GCC flag was
added, allowing optional use of "-Wl,-rpath=".
Then in f5b904db6b ("Makefile: Allow CC_LD_DYNPATH to be overriden",
2008-08-16) the ability to override this flag to something else
entirely was added, as some linkers use neither "-Wl,-rpath," nor
"-R".
From what I can tell we should, with the benefit of hindsight, have
made this change back in 2006. GCC & ld supported this type of
invocation back then, or since at least binutils-gdb.git's[3]
a1ad915dc4 ("[...]Add support for -rpath[...]", 1994-07-20).
Further reading and prior art can be found at [4][5][6][7]. Making a
plain "-R" an error seems from reading those reports to have been
introduced in GCC 4.6 released on March 25, 2011[8], but I couldn't
confirm this with absolute certainty, its release notes are ambiguous
on the subject, and I couldn't be bothered to try to build & bisect it
against GCC 4.5.

However, this must be specified by the user on an

that they may forget to include it and generate a patch series without
notes.
Teach git-format-patch the `format.notes` config option. Its value is a

"standard" can be used to specify the standard notes. This option is
overridable with the `--no-notes` option in case a user wishes not to

When a remote helper exposes the "import" capability, stdout of the
helper is sent to stdin of a new fast-import process. This is done by
setting the corresponding child_process's in field to the value of the
out field of the helper child_process.
The child_process API is defined to close the file descriptors it's
given when calling start_command. This means when start_command is
called for the fast-import process, its input fd (the output fd of the
helper), is closed.
But when the transport helper is later destroyed, in disconnect_helper,
its input and output are closed, which means close() is called with
an invalid fd (since it was already closed as per above). Or worse, with
a valid fd owned by something else (since fd numbers can be reused).

The function's definition has a paramter of type "int" qualified as
"const". The fact that the incoming parameter is used as read-only
in the fuction is an implementation detail that the callers should
not have to be told in the prototype declaring it (and "const" there
has no effect, as C passes parameters by value).
The prototype defined for the function in pkt-line.h lacked the
matching "const" for this reason, but apparently some compilers
(e.g. MS Visual C 2017) complain about the parameter type mismatch.
Let's squelch it by removing the "const" that is pointless in the
definition of a small and trivial function like this, which would
not help optimizing compilers nor reading humans that much.

fill_blame_origin() is a convenient place to store data that we will use
throughout the lifetime of a blame_origin. Some heuristics for
ignoring commits during a blame session can make use of this storage.
In particular, we will calculate a fingerprint for each line of a file
for blame_origins involved in an ignored commit.
In this commit, we only calculate the line_starts, reusing the existing
code from the scoreboard's line_starts. In an upcoming commit, we will
actually compute the fingerprints.
This feature will be used when we attempt to pass blame entries to
parents when we "ignore" a commit. Most uses of fill_blame_origin()
will not require this feature, hence the flag parameter. Multiple calls
to fill_blame_origin() are idempotent, and any of them can request the
creation of the fingerprints structure.

When ignoring commits, the commit that is blamed might not be
responsible for the change, due to the inaccuracy of our heuristic.
Users might want to know when a particular line has a potentially
inaccurate blame.
Furthermore, guess_line_blames() may fail to find any parent commit for
a given line touched by an ignored commit. Those 'unblamable' lines
remain blamed on an ignored commit. Users might want to know if a line
is unblamable so that they do not spend time investigating a commit they
know is uninteresting.
This patch adds two config options to mark these two types of lines in
the output of blame.
The first option can identify ignored lines by specifying
blame.markIgnoredLines. When this option is set, each blame line that
was blamed on a commit other than the ignored commit is marked with a
'?'.
For example:
278b6158d6fdb (Barret Rhoden 2016-04-11 13:57:54 -0400 26)
appears as:
?278b6158d6fd (Barret Rhoden 2016-04-11 13:57:54 -0400 26)
where the '?' is placed before the commit, and the hash has one fewer
characters.
Sometimes we are unable to even guess at what ancestor commit touched a
line. These lines are 'unblamable.' The second option,
blame.markUnblamableLines, will mark the line with '*'.
For example, say we ignore e5e8d36d04cbe, yet we are unable to blame
this line on another commit:
e5e8d36d04cbe (Barret Rhoden 2016-04-11 13:57:54 -0400 26)
appears as:
*e5e8d36d04cb (Barret Rhoden 2016-04-11 13:57:54 -0400 26)
When these config options are used together, every line touched by an
ignored commit will be marked with either a '?' or a '*'.

Commits that make formatting changes or function renames are often not
interesting when blaming a file. A user may deem such a commit as 'not
interesting' and want to ignore and its changes it when assigning blame.
For example, say a file has the following git history / rev-list:
---O---A---X---B---C---D---Y---E---F
Commits X and Y both touch a particular line, and the other commits do
not:
X: "Take a third parameter"
-MyFunc(1, 2);
+MyFunc(1, 2, 3);
Y: "Remove camelcase"
-MyFunc(1, 2, 3);
+my_func(1, 2, 3);
git-blame will blame Y for the change. I'd like to be able to ignore Y:
both the existence of the commit as well as any changes it made. This
differs from -S rev-list, which specifies the list of commits to
process for the blame. We would still process Y, but just don't let the
blame 'stick.'
This patch adds the ability for users to ignore a revision with
--ignore-rev=rev, which may be repeated. They can specify a set of
files of full object names of revs, e.g. SHA-1 hashes, one per line. A
single file may be specified with the blame.ignoreRevFile config option
or with --ignore-rev-file=file. Both the config option and the command
line option may be repeated multiple times. An empty file name "" will
clear the list of revs from previously processed files. Config options
are processed before command line options.
For a typical use case, projects will maintain the file containing
revisions for commits that perform mass reformatting, and their users
have the option to ignore all of the commits in that file.
Additionally, a user can use the --ignore-rev option for one-off
investigation. To go back to the example above, X was a substantive
change to the function, but not the change the user is interested in.
The user inspected X, but wanted to find the previous change to that
line - perhaps a commit that introduced that function call.
To make this work, we can't simply remove all ignored commits from the
rev-list. We need to diff the changes introduced by Y so that we can
ignore them. We let the blames get passed to Y, just like when
processing normally. When Y is the target, we make sure that Y does not
*keep* any blames. Any changes that Y is responsible for get passed to
its parent. Note we make one pass through all of the scapegoats
(parents) to attempt to pass blame normally; we don't know if we *need*
to ignore the commit until we've checked all of the parents.
The blame_entry will get passed up the tree until we find a commit that
has a diff chunk that affects those lines.
One issue is that the ignored commit *did* make some change, and there is
no general solution to finding the line in the parent commit that
corresponds to a given line in the ignored commit. That makes it hard
to attribute a particular line within an ignored commit's diff
correctly.
For example, the parent of an ignored commit has this, say at line 11:
commit-a 11) #include "a.h"
commit-b 12) #include "b.h"
Commit X, which we will ignore, swaps these lines:
commit-X 11) #include "b.h"
commit-X 12) #include "a.h"
We can pass that blame entry to the parent, but line 11 will be
attributed to commit A, even though "include b.h" came from commit B.
The blame mechanism will be looking at the parent's view of the file at
line number 11.
ignore_blame_entry() is set up to allow alternative algorithms for
guessing per-line blames. Any line that is not attributed to the parent
will continue to be blamed on the ignored commit as if that commit was
not ignored. Upcoming patches have the ability to detect these lines
and mark them in the blame output.
The existing algorithm is simple: blame each line on the corresponding
line in the parent's diff chunk. Any lines beyond that stay with the
target.
For example, the parent of an ignored commit has this, say at line 11:
commit-a 11) void new_func_1(void *x, void *y);
commit-b 12) void new_func_2(void *x, void *y);
commit-c 13) some_line_c
commit-d 14) some_line_d
After a commit 'X', we have:
commit-X 11) void new_func_1(void *x,
commit-X 12) void *y);
commit-X 13) void new_func_2(void *x,
commit-X 14) void *y);
commit-c 15) some_line_c
commit-d 16) some_line_d
Commit X nets two additionally lines: 13 and 14. The current
guess_line_blames() algorithm will not attribute these to the parent,
whose diff chunk is only two lines - not four.
When we ignore with the current algorithm, we get:
commit-a 11) void new_func_1(void *x,
commit-b 12) void *y);
commit-X 13) void new_func_2(void *x,
commit-X 14) void *y);
commit-c 15) some_line_c
commit-d 16) some_line_d
Note that line 12 was blamed on B, though B was the commit for
new_func_2(), not new_func_1(). Even when guess_line_blames() finds a
line in the parent, it may still be incorrect.
