This commit is similar to 379805051d ("Documentation: render revisions
correctly under Asciidoctor", 2018-05-06) and is a no-op with AsciiDoc.

When creating a literal block from an indented block without any sort of
delimiters, Asciidoctor strips off all leading whitespace, resulting in
a misrendered ASCII drawing. Use an explicit literal block to indicate
to Asciidoctor that we want to keep the leading whitespace. Drop the
common indentation for all lines to make this a no-op with AsciiDoc.

When we use AsciiDoc, user-manual.conf ensures that the linkgit macro
expands into something like

  <ulink url="git-foo.html">git-foo(1)</ulink>

in user-manual.xml, which we then process into a clickable link, both in
user-manual.html and user-manual.pdf. With Asciidoctor,
user-manual.conf is ignored (this is expected) and our
Asciidoctor-specific implementation of linkgit kicks in:

  <citerefentry>
    <refentrytitle>git-foo</refentrytitle><manvolnum>1</manvolnum>

user-manual.txt: change header notation

When AsciiDoc processes user-manual.txt, it generates a book containing
chapters containing sections. So for example, we have chapter 6,
"Advanced branch management", which contains four relatively short
sections, 6.1-6.4. Asciidoctor generates a book containing *parts*
containing *chapters* instead. So part 6, "Advanced branch management"
contains four short chapters, 1-4. This looks a bit odd.

To make AsciiDoc (8.6.10) and Asciidoctor (1.5.5) handle these the same,
change from indicating chapters like so:

  [[foobar]]
  Foobar
  ======

to doing it like so:

  [[foobar]]
  == Foobar

Same thing for sections (line of dashes to ===), subsections (line of
tildes to ====) and subsubsections (line of carets to =====). Mark the
appendices with "[appendix]", which both AsciiDoc and Asciidoctor
understand. This means we need to drop the "Appendix X: " from their
titles, or those "Appendix X: " would be included literally in the name
of the appendix.

This commit is a no-op for AsciiDoc: The generated user-manual.xml is
identical before and after this patch. Asciidoctor now creates the same
chapter-section-subsection structure as AsciiDoc.

Changing the book title at the start of the document to similarly use
"=" instead of a line of equal signs makes no difference with any of the
engines, but let's do that change anyway for consistency.

Makefile: emulate compile in $(HCO) target better

Currently, when testing headers using `make hdr-check`, headers are
directly compiled. Although this seems to test the headers, this is too
strict since we treat the headers as C sources. As a result, this will
cause warnings to appear that would otherwise not, such as a static
variable definition intended for later use throwing a unused variable
warning.

In addition, on platforms that can run `make hdr-check` but require
custom flags, this target was failing because none of them were being
passed to the compiler. For example, on MacOS, the NO_OPENSSL flag was
being set but it was not being passed into compiler so the check was
failing.

Fix these problems by emulating the compile process better, including
test compiling dummy *.hcc C sources generated from the *.h files and
passing $(ALL_CFLAGS) into the compiler for the $(HCO) target so that
these custom flags can be used.

travis-ci: do not skip successfully tested trees in debug mode

Travis CI offers shell access to its virtual machine environment
running the build jobs, called "debug mode" [1].  After restarting a
build job in debug mode and logging in, the first thing I usually do
is to install dependencies, i.e. run './ci/install-dependencies.sh'.
This works just fine when I restarted a failed build job in debug
mode.  However, after restarting a successful build job in debug mode
our CI scripts get all clever, and exit without doing anything useful,
claiming that "This commit's tree has already been built and tested
successfully" [2].  Our CI scripts are right, and we do want to skip
building and testing already known good trees in "regular" CI builds.
In debug mode, however, this is a nuisiance, because one has to delete
the cache (or at least the 'good-trees' file in the cache) to proceed.

Let's update our CI scripts, in particular the common 'ci/lib.sh', to
not skip previously successfully built and tested trees in debug mode,
so all those scripts will do what there were supposed to do even when
a successful build job was restarted in debug mode.

t/helper: ignore only executable files

This patch conceptually reverts 44103f4197 (t/helper: ignore
everything but sources, 2017-12-12).  Back in those days we did have a
lot of separate test helper executables under 't/helper', and its
'.gitignore' did get out of sync every once in a while.

Since then, however, most of those separate executables were
integrated into a single 'test-tool' command [1], and new test helpers
are added as new subcommands, so the chances of that '.gitignore'
getting out of sync again are much lower.  And even if a contributor
were not careful enough and submits a patch that adds a new executable
under 't/helper' but forgets to update '.gitignore' accordingly, our
CI builds would catch it in a timely manner [2].

Ignoring everything but sources has the drawback that building an
older version of Git (e.g. during bisecting) creates all those
executables, and after going back to e.g. current 'master' the usual
cleanup commands like 'make clean' or 'git clean -fd' don't remove
them (the former doesn't know about them, and the latter doesn't
remove ignored files).

So let's ignore only the executable files under 't/helper/, i.e.
'test-tool' and the three other remaining executables that could not
be integrated into 'test-tool' (no need to ignore object files, as
they are already ignored by our toplevel '.gitignore').

this does not happen.

This is because dir_in_way(), when checking the working tree, thinks

long as the index is only needed in-core, and not re-read from disk.

However in many cases we do actually need the refreshed index to be
written to disk, for example 'merge_recursive_generic()' discards the
in-core index before re-reading it from disk, and in the case of 'apply
--quiet', the 'refresh_cache()' we currently have is pointless without
writing the index to disk.

Always write the index after refreshing it to ensure there are no
regressions in this compared to the scripted stash.  In the future we
can consider avoiding the write where possible after making sure none

However, just because we aren't compiling a source file doesn't mean we

mistakes, in particular ones that affect Windows-only sources since

Make the "coccicheck" target run on all C sources except for those that
are taken from some third-party source. We don't want to patch these
files since we want them to be as close to upstream as possible so that

$(SOURCE_FILES) which would hold a list of filenames from the
$(FIND_SOURCE_FILES) invocation. We would simply filter `%.c` files into
$(ALL_C_SOURCES). $(SOURCE_FILES) would then be passed directly to the
etags, ctags and cscope commands. We can see from the following
invocation

$ git ls-files '*.[hcS]' '*.sh' ':!*[tp][0-9][0-9][0-9][0-9]*' ':!contrib' | wc -c
   12779

that the number of characters in this list would pose a problem on
platforms with short command-line length limits (such as CMD which has a
max of 8191 characters). As a result, we don't perform this change.

However, we can see that the same issue may apply when running
Coccinelle since $(COCCI_SOURCES) is also a list of filenames:

if ! echo $(COCCI_SOURCES) | xargs $$limit \
$(SPATCH) --sp-file $< $(SPATCH_FLAGS) \
>$@+ 2>$@.log; \

This is justified since platforms that support Coccinelle generally have
reasonably long command-line length limits and so we are safe for the
foreseeable future.

Makefile: strip leading ./ in $(FIND_SOURCE_FILES)

Currently, $(FIND_SOURCE_FILES) has two modes: if `git ls-files` is
present, it will use that to enumerate the files in the repository; else
it will use `$(FIND) .` to enumerate the files in the directory.

There is a subtle difference between these two methods, however. With
ls-files, filenames don't have a leading `./` while with $(FIND), they
do. This does not currently pose a problem but in a future patch, we
will be using `filter-out` to process the list of files with the
assumption that there is no prefix.

Unify the two possible invocations in $(FIND_SOURCE_FILES) by using sed
to remove the `./` prefix in the $(FIND) case.

clean: fix theoretical path corruption

cmd_clean() had the following code structure:

        strbuf_addstr(&abs_path, item->string);

where I've elided a bunch of unnecessary details and PROCESS(&abs_path)
represents a big chunk of code rather than an actual function call.  One
piece of PROCESS was:

    if (lstat(abs_path.buf, &st))
        continue;

which would cause the strbuf_reset() to be missed -- meaning that the
next path to be handled would have two paths concatenated.  This path
used to use die_errno() instead of continue prior to commit 396049e5fb62
("git-clean: refactor git-clean into two phases", 2013-06-25), but my
understanding of how correct_untracked_entries() works is that it will
prevent both dir/ and dir/file from being in the list to clean so this
should be dead code and the die_errno() should be safe.  But I hesitate
to remove it since I am not certain.

However, we can fix both this bug and possible similar future bugs by
simply moving the strbuf_reset(&abs_path) to the beginning of the loop.
It'll result in N calls to strbuf_reset() instead of N-1, but that's a
small price to pay to avoid sneaky bugs like this.

5 years agoclean: avoid removing untracked files in a nested git repository
Elijah Newren [Tue, 17 Sep 2019 16:35:02 +0000 (09:35 -0700)]
clean: avoid removing untracked files in a nested git repository

Users expect files in a nested git repository to be left alone unless
sufficiently forced (with two -f's).  Unfortunately, in certain
circumstances, git would delete both tracked (and possibly dirty) files
and untracked files within a nested repository.  To explain how this
happens, let's contrast a couple cases.  First, take the following
example setup (which assumes we are already within a git repo):

   git init nested
   cd nested
   >tracked
   git add tracked
   git commit -m init
   >untracked
   cd ..

In this setup, everything works as expected; running 'git clean -fd'
will result in fill_directory() returning the following paths:
   nested/
   nested/tracked
   nested/untracked
and then correct_untracked_entries() would notice this can be compressed
to
   nested/
and then since "nested/" is a directory, we would call
remove_dirs("nested/", ...), which would
check is_nonbare_repository_dir() and then decide to skip it.

However, if someone also creates an ignored file:
   >nested/ignored
then running 'git clean -fd' would result in fill_directory() returning
the same paths:
   nested/
   nested/tracked
   nested/untracked
but correct_untracked_entries() will notice that we had ignored entries
under nested/ and thus simplify this list to
   nested/tracked
   nested/untracked
Since these are not directories, we do not call remove_dirs() which was
the only place that had the is_nonbare_repository_dir() safety check --
resulting in us deleting both the untracked file and the tracked (and
possibly dirty) file.

One possible fix for this issue would be walking the parent directories
of each path and checking if they represent nonbare repositories, but
that would be wasteful.  Even if we added caching of some sort, it's
still a waste because we should have been able to check that "nested/"
represented a nonbare repository before even descending into it in the
first place.  Add a DIR_SKIP_NESTED_GIT flag to dir_struct.flags and use
it to prevent fill_directory() and friends from descending into nested
git repos.

With this change, we also modify two regression tests added in commit
91479b9c72f1 ("t7300: add tests to document behavior of clean and nested
git", 2015-06-15).  That commit, nor its series, nor the six previous
iterations of that series on the mailing list discussed why those tests
coded the expectation they did.  In fact, it appears their purpose was
simply to test _existing_ behavior to make sure that the performance
changes didn't change the behavior.  However, these two tests directly
contradicted the manpage's claims that two -f's were required to delete
files/directories under a nested git repository.  While one could argue
that the user gave an explicit path which matched files/directories that
were within a nested repository, there's a slippery slope that becomes
very difficult for users to understand once you go down that route (e.g.
what if they specified "git clean -f -d '*.c'"?)  It would also be hard
to explain what the exact behavior was; avoid such problems by making it
really simple.

Also, clean up some grammar errors describing this functionality in the
git-clean manpage.

Finally, there are still a couple bugs with -ffd not cleaning out enough
(e.g.  missing the nested .git) and with -ffdX possibly cleaning out the
wrong files (paying attention to outer .gitignore instead of inner).
This patch does not address these cases at all (and does not change the
behavior relative to those flags), it only fixes the handling when given
a single -f.  See
https://public-inbox.org/git/20190905212043.GC32087@szeder.dev/ for more
discussion of the -ffd[X?] bugs.

5 years agoclean: disambiguate the definition of -d
Elijah Newren [Tue, 17 Sep 2019 16:35:01 +0000 (09:35 -0700)]
clean: disambiguate the definition of -d

The -d flag pre-dated git-clean's ability to have paths specified.  As
such, the default for git-clean was to only remove untracked files in
the current directory, and -d existed to allow it to recurse into
subdirectories.

The interaction of paths and the -d option appears to not have been
carefully considered, as evidenced by numerous bugs and a dearth of
tests covering such pairings in the testsuite.  The definition turns out
to be important, so let's look at some of the various ways one could
interpret the -d option:

  A) Without -d, only look in subdirectories which contain tracked
     files under them; with -d, also look in subdirectories which
     are untracked for files to clean.

  B) Without specified paths from the user for us to delete, we need to
     have some kind of default, so...without -d, only look in
     subdirectories which contain tracked files under them; with -d,
     also look in subdirectories which are untracked for files to clean.

The important distinction here is that choice B says that the presence
or absence of '-d' is irrelevant if paths are specified.  The logic
behind option B is that if a user explicitly asked us to clean a
specified pathspec, then we should clean anything that matches that
pathspec.  Some examples may clarify.  Should

   git clean -f untracked_dir/file

remove untracked_dir/file or not?  It seems crazy not to, but a strict
reading of option A says it shouldn't be removed.  How about

   git clean -f untracked_dir/file1 tracked_dir/file2

or

   git clean -f untracked_dir_1/file1 untracked_dir_2/file2

?  Should it remove either or both of these files?  Should it require
multiple runs to remove both the files listed?  (If this sounds like a
crazy question to even ask, see the commit message of "t7300: Add some
testcases showing failure to clean specified pathspecs" added earlier in
this patch series.)  What if -ffd were used instead of -f -- should that
allow these to be removed?  Should it take multiple invocations with
-ffd?  What if a glob (such as '*tracked*') were used instead of
spelling out the directory names?  What if the filenames involved globs,
such as

   git clean -f '*.o'

or

   git clean -f '*/*.o'

?

The current documentation actually suggests a definition that is
slightly different than choice A, and the implementation prior to this
series provided something radically different than either choices A or
B. (The implementation, though, was clearly just buggy).  There may be
other choices as well.  However, for almost any given choice of
definition for -d that I can think of, some of the examples above will
appear buggy to the user.  The only case that doesn't have negative
surprises is choice B: treat a user-specified path as a request to clean
all untracked files which match that path specification, including
recursing into any untracked directories.

Change the documentation and basic implementation to use this
definition.

There were two regression tests that indirectly depended on the current
implementation, but neither was about subdirectory handling.  These two
tests were introduced in commit 5b7570cfb41c ("git-clean: add tests for
relative path", 2008-03-07) which was solely created to add coverage for
the changes in commit fb328947c8e ("git-clean: correct printing relative
path", 2008-03-07).  Both tests specified a directory that happened to
have an untracked subdirectory, but both were only checking that the
resulting printout of a file that was removed was shown with a relative
path.  Update these tests appropriately.
