Because these constructs can be used to parse user input to be
passed to rev-list --objects, e.g.
range=$(git rev-parse v1.0..v2.0) &&
git rev-list --objects $range | git pack-objects --stdin
the endpoints (v1.0 and v2.0 in the example) are shown without
peeling them to underlying commits, even when they are annotated
tags. Make sure it stays that way.
While at it, ensure "rev-parse A...B" also keeps the endpoints A and
B unpeeled, even though the negative side (i.e. the merge-base
between A and B) has to become a commit.

A low-level API function get_oid(), that accepts various ways to
name an object, used to issue end-user facing error messages
without l10n, which has been updated to be translatable.
* jk/get-oid-error-message-i18n:
sha1-name: mark get_oid() error messages for translation
t1506: drop space after redirection operator
t1400: avoid "test" string comparisons
|
|
Disambiguation logic to tell revisions and pathspec apart has been
tweaked so that backslash-escaped glob special characters do not
count in the "wildcards are pathspec" rule.
* jk/escaped-wildcard-dwim:
verify_filename(): handle backslashes in "wildcards are pathspecs" rule
|
|
There are several error messages in get_oid() and its children that are
clearly intended for humans, but aren't marked for translation. E.g.:
$ git show :1:foo
fatal: Path 'foo' is in the index, but not at stage 1.
Did you mean ':0:foo'?
Let's mark these for translation. While we're at it, let's switch the
style to be more like our usual error messages: start with a lowercase
letter and omit a period at the end of the line.
This does mean that multi-line messages like the one above don't have
any punctuation between the two sentences. I solved that by adding a
"hint" marker like we'd see from advise(). So the result is:
$ git show :1:foo
fatal: path 'foo' is in the index, but not at stage 1
hint: Did you mean ':0:foo'?
A few tests had to be switched to test_i18ngrep and test_i18ncmp. Since
we were touching them anyway, I also simplified the ones using i18ngrep
a bit for readability.

Commit 28fcc0b71a (pathspec: avoid the need of "--" when wildcard is
used, 2015-05-02) allowed:
git rev-parse '*.c'
without the double-dash. But the rule it uses to check for wildcards
actually looks for any glob special. This is overly liberal, as it means
that a pattern that doesn't actually do any wildcard matching, like
"a\b", will be considered a pathspec.
If you do have such a file on disk, that's presumably what you wanted.
But if you don't, the results are confusing: rather than say "there's no
such path a\b", we'll quietly accept it as a pathspec which very likely
matches nothing (or at least not what you intended). Likewise, looking
for path "a\*b" doesn't expand the search at all; it would only find a
single entry, "a*b".
This commit switches the rule to trigger only when glob metacharacters
would expand the search, meaning both of those cases will now report an
error (you can still disambiguate using "--", of course; we're just
tightening the DWIM heuristic).
Note that we didn't test the original feature in 28fcc0b71a at all. So
this patch not only tests for these corner cases, but also adds a
regression test for the existing behavior.

Use test_must_be_empty instead of reading the file and comparing its
contents to an empty string. That's more efficient, as the function
only needs built-in meta-data only check in the usual case, and provides
nicer debug output otherwise.

The object name parser for "Nth parent" syntax has been made more
robust against integer overflows.
* rs/nth-parent-parse:
sha1-name: check for overflow of N in "foo^N" and "foo~N"
rev-parse: demonstrate overflow of N for "foo^N" and "foo~N"
|
|
Reject values that don't fit into an int, as get_parent() and
get_nth_ancestor() cannot handle them. That's better than potentially
returning a random object.
If this restriction turns out to be too tight then we can switch to a
wider data type, but we'd still have to check for overflow.

If the number gets too high for an int, weird things may happen, as
signed overflows are undefined. Add a test to show this; rev-parse
"sucessfully" interprets 100000000000000000000000000000000 to be the
same as 0, at least on x64 with GCC 9.2.1 and Clang 8.0.1, which is
obviously bogus.

In many test scripts, there are bespoke definitions of the single quote

SQ="'"
Define a common $SQ variable in test-lib.sh and replace all usages of

`git grep =\\\\\'` and manually changing the resulting definitions and

Commit a60645f (setup: remember whether repository was
found, 2010-08-05) introduced the startup_info structure,
which records some parts of the setup_git_directory()
process (notably, whether we actually found a repository or
not).
One of the uses of this data is for functions to behave
appropriately based on whether we are in a repo. But the
startup_info struct is just a pointer to storage provided by
the main program, and the only program that sets it up is
the git.c wrapper. Thus builtins have access to
startup_info, but externally linked programs do not.
Worse, library code which is accessible from both has to be
careful about accessing startup_info. This can be used to
trigger a die("BUG") via get_sha1():
$ git fast-import <<-\EOF
tag foo
from HEAD:./whatever
EOF
fatal: BUG: startup_info struct is not initialized.
Obviously that's fairly nonsensical input to feed to
fast-import, but we should never hit a die("BUG"). And there
may be other ways to trigger it if other non-builtins
resolve sha1s.
So let's point the storage for startup_info to a static
variable in setup.c, making it available to all users of the
library code. We _could_ turn startup_info into a regular
extern struct, but doing so would mean tweaking all of the
existing use sites. So let's leave the pointer indirection
in place. We can, however, drop any checks for NULL, as
they will always be false (and likewise, we can drop the
test covering this case, which was a rather artificial
situation using one of the test-* programs).

Rev-parse understands that a "--" may separate revisions and
filenames, and that anything after the "--" is taken as-is.
However, it does not understand that anything before the
token must be a revision (which is the usual rule
implemented by the setup_revisions parser).
Since rev-parse prefers revisions to files when parsing
before the "--", we end up with the correct result (if such
an argument is a revision, we parse it as one, and if it is
not, it is an error either way). However, we misdiagnose
the errors:
$ git rev-parse foobar -- >/dev/null
fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
$ >foobar
$ git rev-parse foobar -- >/dev/null
fatal: bad flag '--' used after filename
In both cases, we should know that the real error is that
"foobar" is meant to be a revision, but could not be
resolved.

Either end of revision range operator can be omitted to default to HEAD,
as in "origin.." (what did I do since I forked) or "..origin" (what did
they do since I forked). But the current parser interprets ".." as an
empty range "HEAD..HEAD", and worse yet, because ".." does exist on the
filesystem, we get this annoying output:
$ cd Documentation/howto
$ git log .. ;# give me recent commits that touch Documentation/ area.
fatal: ambiguous argument '..': both revision and filename
Use '--' to separate filenames from revisions
Surely we could say "git log ../" or even "git log -- .." to disambiguate,
but we shouldn't have to.

verify_filename() can be called in two different contexts. Either we
just tried to interpret a string as an object name, and it fails, so
we try looking for a working tree file (i.e. we finished looking at
revs that come earlier on the command line, and the next argument
must be a pathname), or we _know_ that we are looking for a
pathname, and shouldn't even try interpreting the string as an
object name.
For example, with this change, we get:
$ git log COPYING HEAD:inexistant
fatal: HEAD:inexistant: no such path in the working tree.
Use '-- <path>...' to specify paths that do not exist locally.
$ git log HEAD:inexistant
fatal: Path 'inexistant' does not exist in 'HEAD'

diagnose_invalid_sha1_path() is meant to be called to diagnose a
misspelt <treeish>:<pathname> when <pathname> does not exist in
<treeish>. However, the code may call it if <treeish>:<pathname> is
invalid (which triggers another call with only_to_die == 1), but for
another reason. This happens when calling e.g.
git log existing-file HEAD:existing-file
because existing-file is a path and not a revision, the code
verifies that the arguments that follow to be paths. This leads to
an incorrect message like "existing-file does not exist in HEAD",
even though the path exists in HEAD.
Check that the search for <pathname> in <treeish> fails before
triggering the diagnosis.

Kacper Kornet noticed that a $variable in "word" in the above construct is
not substituted by his pdksh. Modern POSIX compliant shells (e.g. dash,
ksh, bash) all seem to interpret POSIX "2.6.2 Parameter Expansion" that
says "word shall be subjected to tilde expansion, parameter expansion,
command substitution, and arithmetic expansion" in ${parameter<op>word},
to mean that the word is expanded as if it appeared in dq pairs, so if the
word were "'$variable'" (sans dq) it would expand to a single quote, the
value of the $variable and then a single quote.
Johannes Sixt reports that the behavior of quoting at the right of :- when
the ${...:-...} expansion appears in double-quotes was debated recently at
length at the Austin group. We can avoid this issue and future-proof the
test by a slight rewrite.

We taught the object name parser to take ":./<path>", ":../<path>", etc.
and understand them to be relative to the current working directory.
Given that ":<path>" is just a short-hand for ":0:<path>" (i.e. "take
stage #0 of that path"), we should allow ":$n:<path>" to interpret them
the same way.

Currently :path and ref:path can be used to refer to a specific object
in index or ref respectively. "path" component is absolute path. This
patch allows "path" to be written as "./path" or "../path", which is
relative to user's original cwd.
This does not work in commands for which startup_info is NULL
(i.e. non-builtin ones, it seems none of them needs this anyway).

The previous error message was the same in many situations (unknown
revision or path not in the working tree). We try to help the user as
much as possible to understand the error, especially with the
sha1:filename notation. In this case, we say whether the sha1 or the
filename is problematic, and diagnose the confusion between
relative-to-root and relative-to-$PWD confusion precisely.
The 7 new error messages are tested.
