Makefile: make mandir, htmldir and infodir absolute
This is a rewrite of much of Bo's work, mainly in an effort to split
it into smaller, easier to understand routines.
The algorithm is built around the struct range_set, which encodes a
series of line ranges as intervals [a,b). This is used in two
contexts:
* A set of lines we are tracking (which will change as we dig through
history).
* To encode diffs, as pairs of ranges.
The main routine is range_set_map_across_diff(). It processes the
diff between a commit C and some parent P. It determines which diff
hunks are relevant to the ranges tracked in C, and computes the new
ranges for P.
The algorithm is then simply to process history in topological order
from newest to oldest, computing ranges and (partial) diffs. At
branch points, we need to merge the ranges we are watching. We will
find that many commits do not affect the chosen ranges, and mark them
TREESAME (in addition to those already filtered by pathspec limiting).
Another pass of history simplification then gets rid of such commits.
This is wired as an extra filtering pass in the log machinery. This
currently only reduces code duplication, but should allow for other
simplifications and options to be used.
Finally, we hook a diff printer into the output chain. Ideally we
would wire directly into the diff logic, to optionally use features
like word diff. However, that will require some major reworking of
the diff chain, so we completely replace the output with our own diff
for now.
As this was a GSoC project, and has quite some history by now, many
people have helped. In no particular order, thanks go to

We want to use the same style of -L n,m argument for 'git log -L' as
for git-blame. Refactor the argument parsing of the range arguments
from builtin/blame.c to the (new) file that will hold the 'git log -L'
logic.
To accommodate different data structures in blame and log -L, the file
contents are abstracted away; parse_range_arg takes a callback that it
uses to get the contents of a line of the (notional) file.
The new test is for a case that made me pause during debugging: the
'blame -L with invalid end' test was the only one that noticed an
outright failure to parse the end *at all*. So make a more explicit
test for that.

A change made on v1.8.1.x maintenance track had a nasty regression
to break the build when autoconf is used.
* jn/less-reconfigure:
Makefile: avoid infinite loop on configure.ac change
If you are using autoconf and change the configure.ac, the
Makefile will notice that config.status is older than
configure.ac, and will attempt to rebuild and re-run the
configure script to pick up your changes. The first step in
doing so is to run "make configure". Unfortunately, this
tries to include config.mak.autogen, which depends on
config.status, which depends on configure.ac; so we must
rebuild config.status. Which leads to us running "make
configure", and so on.
It's easy to demonstrate with:
make configure
./configure
touch configure.ac
make
We can break this cycle by not re-invoking make to build
"configure", and instead just putting its rules inline into
our config.status rebuild procedure. We can avoid a copy by
factoring the rules into a make variable.

Buggy versions of ccache broke the auto-generation of dependencies.
* jn/auto-depend-workaround-buggy-ccache:
Makefile: explicitly set target name for autogenerated dependencies
An age-old workaround to prevent buggy versions of ccache from
breaking the auto-generation of dependencies, which unfortunately
is still relevant because some people use ancient distros.
* jn/auto-depend-workaround-buggy-ccache:
Makefile: explicitly set target name for autogenerated dependencies
* jc/merge-blobs:
Makefile: Replace merge-file.h with merge-blobs.h in LIB_H
merge-tree: fix d/f conflicts
merge-tree: add comments to clarify what these functions are doing
merge-tree: lose unused "resolve_directories"
merge-tree: lose unused "flags" from merge_list
Which merge_file() function do you mean?
"gcc -MF depfile -MMD -MP -c -o path/to/file.o" produces a makefile
snippet named "depfile" describing what files are needed to build the
target given by "-o". When ccache versions before v3.0pre0~187 (Fix
handling of the -MD and -MDD options, 2009-11-01) run, they execute
gcc -MF depfile -MMD -MP -E
instead to get the final content for hashing. Notice that the "-c -o"
combination is replaced by "-E". The result is a target name without
a leading path.
Thus when building git with such versions of ccache with
COMPUTE_HEADER_DEPENDENCIES enabled, the generated makefile snippets
define dependencies for the wrong target:
$ make builtin/add.o
GIT_VERSION = 1.7.8.rc3
* new build flags or prefix
CC builtin/add.o
$ head -1 builtin/.depend/add.o.d
add.o: builtin/add.c cache.h git-compat-util.h compat/bswap.h strbuf.h \
After a change in a header file, object files in a subdirectory are
not automatically rebuilt by "make":
$ touch cache.h
$ make builtin/add.o
$
Luckily we can prevent trouble by explicitly supplying the name of the
target to ccache and gcc, using the -MQ option. Do so.

Our Makefile first sets up some sane per-platform defaults
by looking at "uname", then modifies that according to the
results of autoconf (if any), then modifies that according
to the user's wishes in config.mak.
For sub-Makefiles like Documentation/Makefile, the latter
two are available, but the uname defaults are available only
to the main Makefile. This hasn't been a problem so far,
because the sub-Makefiles do not rely on any of those
automatic settings to do their work.
This patch puts the uname magic into its own file so it can
be reused in other Makefiles, opening up the possibility of
new knobs.
Note that we leave one reference to uname in the top-level
Makefile: if we are on Darwin, we must check the NO_FINK and
NO_DARWIN_PORTS settings. But because we are combining uname
settings with user-options, we must do so after all of the
config is loaded. This is acceptable, as the resulting
conditionals are about setting variables specific to the
top-level Makefile (and if that ever changes, we can hoist
them into a separate post-config include, too).

Generalize the inclusion of strings.h
Detect when the passwd struct is missing pw_gecos

Starting with v1.7.12-rc0~4^2 (build: reconfigure automatically if
configure.ac changes, 2012-07-19), "config.status --recheck" is
automatically run every time the "configure" script changes. In
particular, that means the configuration procedure repeats whenever
the version number changes (since the configure script changes to
support "./configure --version" and "./configure --help"), making
bisecting painfully slow.
The intent was to make the reconfiguration process only trigger for
changes to configure.ac's logic. Tweak the Makefile rule to match
that intent by depending on configure.ac instead of configure.

Earlier we allowed platforms that lack <sys/param.h> not to include

file since the early days back when we used MAXPATHLEN (which we no
longer use) and also depended on it slurping ULONG_MAX (which we get

It turns out that we can compile our modern codebase just file
without including it on many platforms (so far, Fedora, Debian,
Ubuntu, MinGW, Mac OS X, Cygwin, HP-Nonstop, QNX and z/OS are

Let's stop including it by default, and on platforms that need it to

This is nice except when you run make another time setting a

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

expect a "make install" issued after a "make clean" to rebuild and
install git in '/opt/git'; but with the current behaviour, the

When a C file "foo.c" depends on a generated header file, we
note the dependency for the "foo.o" target. However, we
should also note it for other targets that are built from
foo.c, like "foo.sp" and "foo.s". These tend to be missed
because the latter two are not part of the default build,
and are typically built after a regular build which will
generate the header. Let's be consistent about including
them in dependencies.
This also makes us more consistent with nearby lines which
tack on EXTRA_CPPFLAGS when building certain files. These
flags may sometimes require extra dependencies to be added
(e.g., like GIT-VERSION-FILE; this is not the case for any
of the updated lines in this patch, but it is establishing a
style that will be used in later patches). Technically the
".sp" and ".s" targets do not care about these dependencies,
because they are force-built (".sp" because it is a phony
target, and ".s" because we explicitly force a rebuild).
Since the blocks in question are about communicating "things
built from foo.c depend on these flags", it frees the reader
from having to know or care more about how those targets are
implemented, and why it is OK for only "foo.o" to depend on
GIT-VERSION-FILE while "foo.sp" and "foo.s" both are
impacted by $(GIT_VERSION). And it helps future-proof us if
those force-build details should ever change.
This patch explicitly does not update the static header
dependencies used when COMPUTED_HEADER_DEPENDENCIES is off.
They are similar to the GIT-VERSION-FILE case above, in that
technically "foo.s" would depend on its included headers,
but it is irrelevant because we force-build it anyway. So it
would be tempting to update them in the same way (for
readability and future-proofing). However, those rules are
meant as a fallback to the computed header dependencies,
which do not handle ".s" and ".sp" at all (and are a much
harder problem to solve, as gcc is the one generating those
dependency lists).
So let's leave that harder problem until (and if) somebody
wants to change the ".sp" and ".s" rules, and keep the
static header dependencies consistent with the computed
ones.

Mac OS X mangles file names containing unicode on file systems HFS+,
VFAT or SAMBA. When a file using unicode code points outside ASCII
is created on a HFS+ drive, the file name is converted into
decomposed unicode and written to disk. No conversion is done if
the file name is already decomposed unicode.
Calling open("\xc3\x84", ...) with a precomposed "Ä" yields the same
result as open("\x41\xcc\x88",...) with a decomposed "Ä".
As a consequence, readdir() returns the file names in decomposed
unicode, even if the user expects precomposed unicode. Unlike on
HFS+, Mac OS X stores files on a VFAT drive (e.g. an USB drive) in
precomposed unicode, but readdir() still returns file names in
decomposed unicode. When a git repository is stored on a network
share using SAMBA, file names are send over the wire and written to
disk on the remote system in precomposed unicode, but Mac OS X
readdir() returns decomposed unicode to be compatible with its
behaviour on HFS+ and VFAT.
The unicode decomposition causes many problems:
- The names "git add" and other commands get from the end user may
often be precomposed form (the decomposed form is not easily input
from the keyboard), but when the commands read from the filesystem
to see what it is going to update the index with already is on the
filesystem, readdir() will give decomposed form, which is different.
- Similarly "git log", "git mv" and all other commands that need to
compare pathnames found on the command line (often but not always
precomposed form; a command line input resulting from globbing may
be in decomposed) with pathnames found in the tree objects (should
be precomposed form to be compatible with other systems and for
consistency in general).
- The same for names stored in the index, which should be
precomposed, that may need to be compared with the names read from
readdir().
NFS mounted from Linux is fully transparent and does not suffer from
the above.
As Mac OS X treats precomposed and decomposed file names as equal,
we can
- wrap readdir() on Mac OS X to return the precomposed form, and
- normalize decomposed form given from the command line also to the
precomposed form,
to ensure that all pathnames used in Git are always in the
precomposed form. This behaviour can be requested by setting
"core.precomposedunicode" configuration variable to true.
The code in compat/precomposed_utf8.c implements basically 4 new
functions: precomposed_utf8_opendir(), precomposed_utf8_readdir(),
precomposed_utf8_closedir() and precompose_argv(). The first three
are to wrap opendir(3), readdir(3), and closedir(3) functions.
The argv[] conversion allows to use the TAB filename completion done
by the shell on command line. It tolerates other tools which use
readdir() to feed decomposed file names into git.
When creating a new git repository with "git init" or "git clone",
"core.precomposedunicode" will be set "false".
The user needs to activate this feature manually. She typically
sets core.precomposedunicode to "true" on HFS and VFAT, or file
systems mounted via SAMBA.

We keep a list of most of the header files in LIB_H, but
some are split out into MISC_H. The original point
of LIB_H was that it would force recompilation of C files
when any of the library headers changed. It was
over-encompassing, since not all C files included all of the
library headers; this made it simple to maintain, but meant
that we sometimes recompiled when it was not necessary.
Over time, some new headers were omitted from LIB_H, and
rules were added to the Makefile for a few specific targets
to explicitly depend on them. This avoided some unnecessary
recompilation at the cost of having to maintain the
dependency list of those targets manually (e.g., d349a03).
Later, we needed a complete list of headers from which we
should extract strings to localized. Thus 1b8b2e4 introduced
MISC_H to mention all header files not included in LIB_H,
and the concatenation of the two lists is fed to xgettext.
Headers mentioned as dependencies must also be manually
added to MISC_H to receive the benefits of localization.
Having to update multiple locations manually is a pain and
has led to errors. For example, see "git log -Swt-status.h
Makefile" for some back-and-forth between the two locations.
Or the fact that column.h was never added to MISC_H, and
therefore was not localized (which is fixed by this patch).
Moreover, the benefits of keeping these few headers out of
LIB_H is not that great, for two reasons:
1. The better way to do this is by auto-computing the
dependencies, which is more accurate and less work to
maintain. If your compiler supports it, we turn on
computed header dependencies by default these days. So
these manual dependencies are used only for people who
do not have gcc at all (which increases the chance of
them becoming stale, as many developers will never even
use them).
2. Even if you do not have gcc, the manual header
dependencies do not help all that much. They obviously
cannot help with an initial compilation (since their
purpose is to avoid unnecessary recompilation when a
header changes), which means they are only useful when
building a new version of git in the working tree that
held an existing build (e.g., after checkout or during a
bisection). But since a change of a header in LIB_H
will force recompilation, and given that the vast
majority of headers are in LIB_H, most version changes
will result in a full rebuild anyway.
Let's just fold MISC_H into LIB_H and get rid of these
manual rules. The worst case is some extra compilation, but
even that is unlikely to matter due to the reasons above.
The one exception is that we should keep common-cmds.h
separate. Because it is generated, the computed dependencies
do not handle it properly, and we must keep separate
individual dependencies on it. Let's therefore rename MISC_H
to GENERATED_H to make it more clear what should go in it.

advertise their git version (for privacy or security
reasons) can tweak it.

The global git_version_string currently lives in git.c, but
doesn't have anything to do with the git wrapper. Let's move
it into its own file, where it will be more appropriate to
build more version-related functions.

In 20fc9bc (Set HTTP user agent to git/GIT_VERSION, 2006-04-04),
http.o started recording GIT_VERSION, but http.o wasn't added
to the list of files that depends on GIT-VERSION-FILE.
Fix this, so mofications to GIT-VERSION-FILE will result in an
updated user-agent string.

When we made the switch to supporting asciidoc 8 in 4c7100a
(Documentation: adjust to AsciiDoc 8, 2007-06-14), we were
able to leave most of the documentation intact by defining
asciidoc7compatible.
Since commit 6cf378f (docs: stop using asciidoc no-inline-literal,
2012-04-26), we don't support versions of asciidoc older
than 8.4.1, which is when inline literals were introduced.
Therefore there is not much point in keeping our
documentation compatible with asciidoc 7.
So we are now free to drop the asciidoc7compatible flag and
update the documentation itself to assume asciidoc8.
Fortunately, doing the latter is very easy; we weren't using
any of the constructs impacted by asciidoc7compatible, so
there are no changes to make.
The reason is somewhat subtle. The asciidoc7compatible
affects only super/sub-scripts ("^" and "~") and index
terms. We don't use the latter at all. Nor we do we use the
former, but we did have to protect them from accidental
expansion in constructs like "rev^1". However, all of our
uses of "~" and "^" are either in code blocks (which are
rendered literally), or inside backticks. Prior to 6cf378f,
backticks were not inline literals, and needed proper
quoting. But post-6cf378f, we don't have to worry whether we
are using the old or new rules, as those characters are not
interpreted at all in either case.
I verified that the result of "make install-html
install-man" is identical before and after this patch on
asciidoc 8.6.7.

Enables threading in index-pack to resolve base data in parallel.
By Nguyễn Thái Ngọc Duy (3) and Ramsay Jones (1)
* nd/threaded-index-pack:
index-pack: disable threading if NO_PREAD is defined
index-pack: support multithreaded delta resolving
index-pack: restructure pack processing into three main functions
compat/win32/pthread.h: Add an pthread_key_delete() implementation
Your build platform may support hardlinks but you may prefer not to use
them, e.g. when installing to DESTDIR to make a tarball and untarring on
a filesystem that has poor support for hardlinks.
The Makefile in git-gui project may need to learn to honor the same
setting; it unconditionally creates git-citool by hardlinking git-gui.
* jc/install-no-hardlinks:
Makefile: NO_INSTALL_HARDLINKS
This puts delta resolving on each base on a separate thread, one base
cache per thread. Per-thread data is grouped in struct thread_local.
When running with nr_threads == 1, no pthreads calls are made. The
system essentially runs in non-thread mode.
An experiment on a Xeon 24 core machine with git.git shows that
performance does not increase proportional to the number of cores. So
by default, we use maximum 3 cores. Some numbers with --threads from 1

Your filesystem may support hardlinks, but you may choose not to use them
when installing git-foo builtins and favor symblic links or copies for
whatever reason.
The installation procedure of git-gui/ directory is not touched with this
patch and git-citool still ends up being a hardlink to git-gui, but it
needs to be addressed separately.

i18n: index-pack: mark strings for translation
i18n: apply: update say_patch_name to give translators complete sentence

Trivially shrinks the on-disk size of the index file to save both I/O and
checksum overhead.
The topic should give a solid base to build on further updates, with the
code refactoring in its earlier parts, and the backward compatibility
mechanism in its later parts.
* jc/index-v4:
index-v4: document the entry format
unpack-trees: preserve the index file version of original
update-index: upgrade/downgrade on-disk index version
read-cache.c: write prefix-compressed names in the index
read-cache.c: read prefix-compressed names in index on-disk version v4
read-cache.c: move code to copy incore to ondisk cache to a helper function
read-cache.c: move code to copy ondisk to incore cache to a helper function
read-cache.c: report the header version we do not understand
read-cache.c: make create_from_disk() report number of bytes it consumed
read-cache.c: allow unaligned mapping of the index file
cache.h: hide on-disk index details
varint: make it available outside the context of pack
A column option string consists of many token separated by either
a space or a comma. A token belongs to one of three groups:
- enabling: always, never and auto
- layout mode: currently plain (which does not layout at all)
- other future tuning flags
git-column can be used to pipe output to from a command that wants
column layout, but not to mess with its own output code. Simpler output
code can be changed to use column layout code directly.
