Some people feel the default set of colors used by "git log --graph"
rather limiting. A mechanism to customize the set of colors has
been introduced.
* nd/log-graph-configurable-colors:
document behavior of empty color name
color_parse_mem: allow empty color spec
log --graph: customize the graph lines with config log.graphColors
color.c: trim leading spaces in color_parse_mem()
color.c: fix color_parse_mem() with value_len == 0
|
|
Prior to c2f41bf52 (color.c: fix color_parse_mem() with
value_len == 0, 2017-01-19), the empty string was
interpreted as a color "reset". This was an accidental
outcome, and that commit turned it into an error.
However, scripts may pass the empty string as a default
value to "git config --get-color" to disable color when the
value is not defined. The git-add--interactive script does
this. As a result, the script is unusable since c2f41bf52
unless you have color.diff.plain defined (if it is defined,
then we don't parse the empty default at all).
Our test scripts didn't notice the recent breakage because
they run without a terminal, and thus without color. They
never hit this code path at all. And nobody noticed the
original buggy "reset" behavior, because it was effectively
a noop.
Let's fix the code to have an empty color name produce an
empty sequence of color codes. The tests need a few fixups:
- we'll add a new test in t4026 to cover this case. But
note that we need to tweak the color() helper. While
we're there, let's factor out the literal ANSI ESC
character. Otherwise it makes the diff quite hard to
read.
- we'll add a basic sanity-check in t4026 that "git add
-p" works at all when color is enabled. That would have
caught this bug, as well as any others that are specific
to the color code paths.
- 73c727d69 (log --graph: customize the graph lines with
config log.graphColors, 2017-01-19) added a test to
t4202 that checks some "invalid" graph color config.
Since ",, blue" before yielded only "blue" as valid, and
now yields "empty, empty, blue", we don't match the
expected output.
One way to fix this would be to change the expectation
to the empty color strings. But that makes the test much
less interesting, since we show only two graph lines,
both of which would be colorless.
Since the empty-string case is now covered by t4026,
let's remove them entirely here. They're just in the way
of the primary thing the test is supposed to be
checking.

* jk/squelch-false-warning-from-gcc-o3:
color_parse_mem: initialize "struct color" temporary
error_errno: use constant return similar to error()
|
|
Compiling color.c with gcc 6.2.0 using -O3 produces some
-Wmaybe-uninitialized false positives:
color.c: In function ‘color_parse_mem’:
color.c:189:10: warning: ‘bg.blue’ may be used uninitialized in this function [-Wmaybe-uninitialized]
out += xsnprintf(out, len, "%c8;2;%d;%d;%d", type,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
c->red, c->green, c->blue);
~~~~~~~~~~~~~~~~~~~~~~~~~~
color.c:208:15: note: ‘bg.blue’ was declared here
struct color bg = { COLOR_UNSPECIFIED };
^~
[ditto for bg.green, bg.red, fg.blue, etc]
This is doubly confusing, because the declaration shows it
being initialized! Even though we do not explicitly
initialize the color components, an incomplete initializer
sets the unmentioned members to zero.
What the warning doesn't show is that we later do this:
struct color c;
if (!parse_color(&c, ...)) {
if (fg.type == COLOR_UNSPECIFIED)
fg = c;
...
}
gcc is clever enough to realize that a struct assignment
from an uninitialized variable taints the destination. But
unfortunately it's _not_ clever enough to realize that we
only look at those members when type is set to COLOR_RGB, in
which case they are always initialized.
With -O2, gcc does not look into parse_color() and must
assume that "c" emerges fully initialized. With -O3, it
inlines parse_color(), and learns just enough to get
confused.
We can silence the false positive by initializing the
temporary "c". This also future-proofs us against
violating the type assumptions (the result would probably
still be buggy, but in a deterministic way).

The list of attributes we recognize is a bit unwieldy, as we
actually have two arrays that must be kept in sync. Instead,
let's have a single array-of-struct to represent our
mapping. That means we can never have an accident that
causes us to read off the end of an array, and it makes
diffs for adding new attributes much easier to read.
This also makes it easy to handle the "no" cases without
having to repeat each attribute (this shortens the list,
making it easier to read, but also also cuts the size of our
linear search in half). Technically this makes it impossible
for us to add an attribute that starts with "no" (we could
confuse "nobody" for the negation of "body"), but since this
is a constrained set of attributes, that's OK.
Since we can also store the length of each name in the
struct, that makes it easy for us to avoid reading past the
"len" parameter given to us (though in practice it was not a
bug, since all of our current callers are interested in a
subset of a NUL-terminated buffer, not a true undelimited
range of memory).

To set up default colors, we sometimes strcpy() from the
default string literals into our color buffers. This isn't a
bug (assuming the destination is COLOR_MAXLEN bytes), but
makes it harder to audit the code for problematic strcpy
calls.
Let's introduce a color_set which copies under the
assumption that there are COLOR_MAXLEN bytes in the
destination (of course you can call it on a smaller buffer,
so this isn't providing a huge amount of safety, but it's
more convenient than calling xsnprintf yourself).

Our color parsing is designed to never exceed COLOR_MAXLEN
bytes. But the relationship between that hand-computed
number and the parsing code is not at all obvious, and we
merely hope that it has been computed correctly for all
cases.
Let's mark the expected "end" pointer for the destination
buffer and make sure that we do not exceed it.

Commit 695d95d (parse_color: refactor color storage,
2014-11-20) introduced two macros, COLOR_FOREGROUND and
COLOR_BACKGROUND. The latter conflicts with a system macro
defined on Windows, breaking compilation there.
The simplest solution is to just get rid of these macros
entirely. They are constants that are only used in one place
(since the whole point of 695d95d was to avoid repeating
ourselves). Their main function is to make the magic
character constants more readable, but we can do the same

You can turn on ANSI text attributes like "reverse" by
putting "reverse" in your color spec. However, you cannot
ask to turn reverse off.
For common cases, this does not matter. You would turn on
"reverse" at the start of a colored section, and then clear
all attributes with a "reset". However, you may wish to turn
on some attributes, then selectively disable others. For
example:
git log --format="%C(bold ul yellow)%h%C(noul) %s"
underlines just the hash, but without the need to re-specify
the rest of the attributes. This can also help third-party
programs, like contrib/diff-highlight, that want to turn
some attribute on/off without disrupting existing coloring.
Note that some attribute specifications are probably
nonsensical (e.g., "bold nobold"). We do not bother to flag
such constructs, and instead let the terminal sort it out.

When we parse a color name like "red" into its ANSI color
value, we pack the storage into a single int that may take
on many values:
1. If it's "-2", no value has been specified.
2. If it's "-1", the value is "normal" (i.e., no color).
3. If it's 0 through 7, the value is a standard ANSI
color.
4. If it's larger (up to 255), it is a 256-color extended
value.
Given these magic numbers, it is often hard to see what is
going on in the code. Let's refactor this into a struct with
a flag that tells which scheme we are using, along with a
numeric value. This is more verbose, but should hopefully be
simpler to follow. It will also allow us to easily add
support for more schemes, like 24-bit RGB values.
The result is also slightly less efficient to store, but
that's OK; we only store this intermediate state during the
parse, after which we write out the actual ANSI bytes.

Originally the color-parsing function was used only for
config variables. It made sense to pass the variable name so
that the die() message could be something like:
$ git -c color.branch.plain=bogus branch
fatal: bad color value 'bogus' for variable 'color.branch.plain'
These days we call it in other contexts, and the resulting
error messages are a little confusing:
$ git log --pretty='%C(bogus)'
fatal: bad color value 'bogus' for variable '--pretty format'
$ git config --get-color foo.bar bogus
fatal: bad color value 'bogus' for variable 'command line'
This patch teaches color_parse to complain only about the
value, and then return an error code. Config callers can
then propagate that up to the config parser, which mentions
the variable name. Other callers can provide a custom
message. After this patch these three cases now look like:
$ git -c color.branch.plain=bogus branch
error: invalid color value: bogus
fatal: unable to parse 'color.branch.plain' from command-line config
$ git log --pretty='%C(bogus)'
error: invalid color value: bogus
fatal: unable to parse --pretty format
$ git config --get-color foo.bar bogus
error: invalid color value: bogus
fatal: unable to parse default color value

Most users seem to like having colors enabled, and colors can help
beginners to understand the output of some commands (e.g. notice
immediately the boundary between commits in the output of "git log").
Many tutorials tell the users to set color.ui=auto as a very first step,
which tend to indicate that color.ui=none is not the recommanded value,
hence should not be the default.
These tutorials would benefit from skipping this step and starting the
real Git manipulations earlier. Other beginners do not know about
color.ui=auto, and may not discover it by themselves, hence live with
black&white outputs while they may have preferred colors.
A few people (e.g. color-blind) prefer having no colors, but they can
easily set color.ui=never for this (and googling "disable colors in git"
already tells them how to do so), but this needs not occupy space in
beginner-oriented documentations.
A transition period with Git emitting a warning when color.ui is unset
would be possible, but the discomfort of having the warning seems
superior to the benefit: users may be surprised by the change, but not
harmed by it.
The default value is changed, and the documentation is reworded to
mention "color.ui=false" first, since the primary use of color.ui after
this change is to disable colors, not to enable it.

All of the "do we want color" flags default to -1 to
indicate that we don't have any color configured. This value
is handled in one of two ways:
1. In porcelain, we check early on whether the value is
still -1 after reading the config, and set it to the
value of color.ui (which defaults to 0).
2. In plumbing, it stays untouched as -1, and want_color
defaults it to off.
This works fine, but means that every porcelain has to check
and reassign its color flag. Now that want_color gives us a
place to put this check in a single spot, we can do that,
simplifying the calling code.

The diff config callback is split into two functions: one
which loads "ui" config, and one which loads "basic" config.
The former chains to the latter, as the diff UI config is a
superset of the plumbing config.
The color.diff variable is only loaded in the UI config.
However, the basic config actually chains to
git_color_default_config, which loads color.ui. This doesn't
actually cause any bugs, because the plumbing diff code does
not actually look at the value of color.ui.
However, it is somewhat nonsensical, and it makes it
difficult to refactor the color code. It probably came about
because there is no git_color_config to load only color
config, but rather just git_color_default_config, which
loads color config and chains to git_default_config.
This patch splits out the color-specific portion of
git_color_default_config so that the diff UI config can call
it directly. This is perhaps better explained by the
chaining of callbacks. Before we had:
git_diff_ui_config
-> git_diff_basic_config
-> git_color_default_config
-> git_default_config
Now we have:
git_diff_ui_config
-> git_color_config
-> git_diff_basic_config
-> git_default_config

When we read a color value either from a config file or from
the command line, we use git_config_colorbool to convert it
from the tristate always/never/auto into a single yes/no
boolean value.
This has some timing implications with respect to starting
a pager.
If we start (or decide not to start) the pager before
checking the colorbool, everything is fine. Either isatty(1)
will give us the right information, or we will properly
check for pager_in_use().
However, if we decide to start a pager after we have checked
the colorbool, things are not so simple. If stdout is a tty,
then we will have already decided to use color. However, the
user may also have configured color.pager not to use color
with the pager. In this case, we need to actually turn off
color. Unfortunately, the pager code has no idea which color
variables were turned on (and there are many of them
throughout the code, and they may even have been manipulated
after the colorbool selection by something like "--color" on
the command line).
This bug can be seen any time a pager is started after
config and command line options are checked. This has
affected "git diff" since 89d07f7 (diff: don't run pager if
user asked for a diff style exit code, 2007-08-12). It has
also affect the log family since 1fda91b (Fix 'git log'
early pager startup error case, 2010-08-24).
This patch splits the notion of parsing a colorbool and
actually checking the configuration. The "use_color"
variables now have an additional possible value,
GIT_COLOR_AUTO. Users of the variable should use the new
"want_color()" wrapper, which will lazily determine and
cache the auto-color decision.

Usually this function figures out for itself whether stdout
is a tty. However, it has an extra parameter just to allow
git-config to override the auto-detection for its
--get-colorbool option.
Instead of an extra parameter, let's just use a global
variable. This makes calling easier in the common case, and
will make refactoring the colorbool code much simpler.

This gives it the same behavior as we had prior to 1d28232
(status: show branchname with a configurable color).
To do this we need the concept of a "NIL" color, which is
provided by color.[ch]. The implementation is very simple;
in particular, there are no precautions taken against code
accidentally printing the NIL. This should be fine in
practice because:
1. You can't input a NIL color in the config, so it must
come from the in-code defaults. Which means it is up
the client code to handle the NILs it defines.
2. If we do ever print a NIL, it will be obvious what the
problem is, and the bug can be fixed.

This teaches the --color-words engine a more general interface that
supports two new modes:
* --word-diff=plain, inspired by the 'wdiff' utility (most similar to
'wdiff -n <old> <new>'): uses delimiters [-removed-] and {+added+}
* --word-diff=porcelain, which generates an ad-hoc machine readable
format:
- each diff unit is prefixed by [-+ ] and terminated by newline as
in unified diff
- newlines in the input are output as a line consisting only of a
tilde '~'
Both of these formats still support color if it is enabled, using it
to highlight the differences. --color-words becomes a synonym for
--word-diff=color, which is the color-only format. Also adds some
compatibility/convenience options.

Make git-branch, git-show-branch, git-grep, and all the diff-based
programs accept an optional argument <when> for --color. The argument
is a colorbool: "always", "never", or "auto". If no argument is given,
"always" is used; --no-color is an alias for --color=never. This makes
the command-line interface consistent with other GNU tools, such as `ls'
and `grep', and with the git-config color options. Note that, without
an argument, --color and --no-color work exactly as before.
To implement this, two internal changes were made:
1. Allow the first argument of git_config_colorbool() to be NULL,
in which case it returns -1 if the argument isn't "always", "never",
or "auto".
2. Add OPT_COLOR_FLAG(), OPT__COLOR(), and parse_opt_color_flag_cb()
to the option parsing library. The callback uses
git_config_colorbool(), so color.h is now a dependency
of parse-options.c.

Commit 5ef8d77a implemented color_parse_mem, a function for
parsing colors from a non-NUL-terminated string, by simply
allocating a new NUL-terminated string and calling
color_parse. This had a small but measurable speed impact on
a user format that used the advanced color parsing. E.g.,
# uses quick parsing
$ time ./git log --pretty=tformat:'%Credfoo%Creset' >/dev/null
real 0m0.673s
user 0m0.652s
sys 0m0.016s
# uses color_parse_mem
$ time ./git log --pretty=tformat:'%C(red)foo%C(reset)' >/dev/null
real 0m0.692s
user 0m0.660s
sys 0m0.032s
This patch implements color_parse_mem as the primary
function, with color_parse as a wrapper for strings. This
gives comparable timings to the first case above.

We have very featureful color-parsing routines which are
used for color.diff.* and other options. Let's make it
easier to use those routines from other parts of the code.
This patch adds a color_parse_mem() helper function which
takes a length-bounded string instead of a NUL-terminated
one. While the helper is only a few lines long, it is nice
to abstract this out so that:
- callers don't forget to free() the temporary buffer
- right now, it is implemented in terms of color_parse().
But it would be more efficient to reverse this and
implement color_parse in terms of color_parse_mem.
This also changes the error string for an invalid color not
to mention the word "config", since it is not always
appropriate (and when it is, the context is obvious since
the offending config variable is given).
Finally, while we are in the area, we clean up the parameter
names in the declaration of color_parse; the var and value
parameters were reversed from the actual implementation.

When deciding whether or not to turn on automatic color
support, git_config_colorbool checks whether stdout is a
tty. However, because we run a pager, if stdout is not a
tty, we must check whether it is because we started the
pager. This used to be done by checking the pager_in_use
variable.
This variable was set only when the git program being run
started the pager; there was no way for an external program
running git indicate that it had already started a pager.
This patch allows a program to set GIT_PAGER_IN_USE to a
true value to indicate that even though stdout is not a tty,
it is because a pager is being used.

This adds an option to help scripts find out color settings from
the configuration file.
git config --get-colorbool color.diff
inspects color.diff variable, and exits with status 0 (i.e. success) if
color is to be used. It exits with status 1 otherwise.
If a script wants "true"/"false" answer to the standard output of the
command, it can pass an additional boolean parameter to its command
line, telling if its standard output is a terminal, like this:
git config --get-colorbool color.diff true
When called like this, the command outputs "true" to its standard output
if color is to be used (i.e. "color.diff" says "always", "auto", or
"true"), and "false" otherwise.

Too many people got burned by setting color.diff and color.status to
true when they really should have set it to "auto".
This makes only "always" to do the unconditional colorization, and
change the meaning of "true" to the same as "auto": colorize only when
we are talking to a terminal.

Still defaults to stdout, but you can now override wt_status.fp after
calling wt_status_prepare().

This is a mechanical clean-up of the way *.c files include
system header files.
(1) sources under compat/, platform sha-1 implementations, and
xdelta code are exempt from the following rules;
(2) the first #include must be "git-compat-util.h" or one of
our own header file that includes it first (e.g. config.h,
builtin.h, pkt-line.h);
(3) system headers that are included in "git-compat-util.h"
need not be included in individual C source files.
(4) "git-compat-util.h" does not have to include subsystem
specific header files (e.g. expat.h).

The intent is to lib-ify colorizing code so it can be reused.
