René Scharfe	59fa5f5a25	sha1-name: check for overflow of N in "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.

René Scharfe	a678df1bf9	rev-parse: demonstrate overflow of N for "foo^N" and "foo~N" 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.

Denton Liu	bd482d6e33	t: use common $SQ variable In many test scripts, there are bespoke definitions of the single quote that are some variation of this: SQ="'" Define a common $SQ variable in test-lib.sh and replace all usages of these bespoke variables with the common one. This change was done by running `git grep =\"\'\" t/` and `git grep =\\\\\'` and manually changing the resulting definitions and corresponding usages.

Alexander Shopov	fc045fe7d4	Mark messages for translations Small changes in messages to fit the style and typography of rest. Reuse already translated messages if possible. Do not translate messages aimed at developers of git. Fix unit tests depending on the original string. Use `test_i18ngrep` for tests with translatable strings. Change and verify rest of tests via `make GETTEXT_POISON=1 test`. Signed-off-by: Alexander Shopov <ash@kambanaria.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>	7 years ago

Jeff King	46c3cd44d7	setup: make startup_info available everywhere 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).

Jeff King	1418567381	rev-parse: correctly diagnose revision errors before "--" 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.

Junio C Hamano	003c84f6d2	specifying ranges: we did not mean to make ".." an empty set 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.

Matthieu Moy	023e37c377	verify_filename(): ask the caller to chose the kind of diagnosis 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' Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago
Matthieu Moy	d7236c4395	sha1_name: do not trigger detailed diagnosis for file arguments 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.

Junio C Hamano	365c2aaafc	t1507: avoid "${parameter<op>'word'}" inside double-quotes 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. Helped-by: Johannes Sixt <j.sixt@viscovery.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	14 years ago

Junio C Hamano	3d6e0f745e	get_sha1: teach ":$n:<path>" the same relative path logic We taught the object name parser to take ":./<path>", ":../<path>", etc. and understand them to be relative to the current working directory. Given that ":<path>" is just a short-hand for ":0:<path>" (i.e. "take stage #0 of that path"), we should allow ":$n:<path>" to interpret them the same way.

Nguyễn Thái Ngọc Duy	979f792951	get_sha1: support relative path ":path" syntax 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).

Matthieu Moy	009fee4774	Detailed diagnosis when parsing an object name fails. 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. Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
