2019-04-25Merge branch 'sg/blame-in-bare-start-at-head'Libravatar Junio C Hamano1-0/+13
"git blame -- path" in a non-bare repository starts blaming from the working tree, and the same command in a bare repository errors out because there is no working tree by definition. The command has been taught to instead start blaming from the commit at HEAD, which is more useful. * sg/blame-in-bare-start-at-head: blame: default to HEAD in a bare repo when no start commit is given

2019-04-08blame: default to HEAD in a bare repo when no start commit is givenLibravatar SZEDER Gábor1-0/+13
When 'git blame' is invoked without specifying the commit to start blaming from, it starts from the given file's state in the work tree. However, when invoked in a bare repository without a start commit, then there is no work tree state to start from, and it dies with the following error message: $ git rev-parse --is-bare-repository true $ git blame file.c fatal: this operation must be run in a work tree This is misleading, because it implies that 'git blame' doesn't work in bare repositories at all, but it does, in fact, work just fine when it is given a commit to start from. We could improve the error message, of course, but let's just default to HEAD in a bare repository instead, as most likely that is what the user wanted anyway (if they wanted to start from an other commit, then they would have specified that in the first place). 'git annotate' is just a thin wrapper around 'git blame', so in the same situation it printed the same misleading error message, and this patch fixes it, too.

2019-04-08ls-files: use correct format stringLibravatar Thomas Gummerer1-5/+5
struct stat_data and struct cache_time both use unsigned ints for all their members. However the format string for 'git ls-files --debug' currently uses %d for formatting these numbers. This means that we potentially print these values incorrectly if they are greater than INT_MAX. This has been the case since the --debug option was introduced in 'git ls-files' in 8497421715 ("ls-files: learn a debugging dump format", 2010-07-31).

2019-04-01index-pack: show progress while checking objectsLibravatar SZEDER Gábor1-1/+9
When 'git index-pack' is run by 'git clone', its check_objects() function usually doesn't take long enough to be a concern, but I just run into a situation where it took about a minute or so: I inadvertently put some memory pressure on my tiny laptop while cloning linux.git, and then there was quite a long silence between the "Resolving deltas" and "Checking connectivity" progress bars.

2019-04-01gc: handle & check gc.reflogExpire configLibravatar Ævar Arnfjörð Bjarmason1-0/+17
Don't redundantly run "git reflog expire --all" when gc.reflogExpire and gc.reflogExpireUnreachable are set to "never", and die immediately if those configuration valuer are bad. As an earlier "assert lack of early exit" change to the tests for "git reflog expire" shows, an early check of gc.reflogExpire{Unreachable,} isn't wanted in general for "git reflog expire", but it makes sense for "gc" because: 1) Similarly to 8ab5aa4bd8 ("parseopt: handle malformed --expire arguments more nicely", 2018-04-21) we'll now die early if the config variables are set to invalid values. We run "pack-refs" before "reflog expire", which can take a while, only to then die on an invalid gc.reflogExpire{Unreachable,} configuration. 2) Not invoking the command at all means it won't show up in trace output, which makes what's going on more obvious when the two are set to "never". 3) As a later change documents we lock the refs when looping over the refs to expire, even in cases where we end up doing nothing due to this config. For the reasons noted in the earlier "assert lack of early exit" change I don't think it's worth it to bend over backwards in "git reflog expire" itself to carefully detect if we'll really do nothing given the combination of all its possible options and skip that locking, but that's easy to detect here in "gc" where we'll only run "reflog expire" in a relatively simple mode.

2019-04-01commit-graph verify: detect inability to read the graphLibravatar Ævar Arnfjörð Bjarmason1-1/+3
Change "commit-graph verify" to error on open() failures other than ENOENT. As noted in the third paragraph of 283e68c72f ("commit-graph: add 'verify' subcommand", 2018-06-27) and the test it added it's intentional that "commit-graph verify" doesn't error out when the file doesn't exist. But let's not be overly promiscuous in what we accept. If we can't read the file for other reasons, e.g. permission errors, bad file descriptor etc. we'd like to report an error to the user.

2019-04-01commit-graph: don't pass filename to load_commit_graph_one_fd_st()Libravatar Ævar Arnfjörð Bjarmason1-2/+2
An earlier change implemented load_commit_graph_one_fd_st() in a way that was bug-compatible with earlier code in terms of the "graph file %s is too small" error message printing out the path to the commit-graph (".git/objects/info/commit-graph"). But change that, because: * A function that takes an already-open file descriptor also needing the filename isn't very intuitive. * The vast majority of errors we might emit when loading the graph come from parse_commit_graph(), which doesn't report the filename. Let's not do that either in this case for consistency. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-04-01commit-graph: don't early exit(1) on e.g. "git status"Libravatar Ævar Arnfjörð Bjarmason1-4/+17
Make the commit-graph loading code work as a library that returns an error code instead of calling exit(1) when the commit-graph is corrupt. This means that e.g. "status" will now report commit-graph corruption as an "error: [...]" at the top of its output, but then proceed to work normally. This required splitting up the load_commit_graph_one() function so that the code that deals with open()-ing and stat()-ing the graph can now be called independently as open_commit_graph(). This is needed because "commit-graph verify" where the graph doesn't exist isn't an error. See the third paragraph in 283e68c72f ("commit-graph: add 'verify' subcommand", 2018-06-27). There's a bug in that logic where we conflate the intended ENOENT with other errno values (e.g. EACCES), but this change doesn't address that. That'll be addressed in a follow-up change. I'm then splitting most of the logic out of load_commit_graph_one() into load_commit_graph_one_fd_st(), which allows for providing an existing file descriptor and stat information to the loading code. This isn't strictly needed, but it would be redundant and confusing to open() and stat() the file twice for some of the codepaths, this allows for calling open_commit_graph() followed by load_commit_graph_one_fd_st(). The "graph_file" still needs to be passed to that function for the the "graph file %s is too small" error message. This leaves load_commit_graph_one() unused by everything except the internal prepare_commit_graph_one() function, so let's mark it as "static". If someone needs it in the future we can remove the "static" attribute. I could also rewrite its sole remaining user ("prepare_commit_graph_one()") to use load_commit_graph_one_fd_st() instead, but let's leave it at this.

2019-03-24checkout: prevent losing staged changes with --mergeLibravatar Nguyễn Thái Ngọc Duy1-1/+10
When --merge is specified, we may need to do a real merge (instead of three-way tree unpacking), the steps are best seen in git-checkout.sh version before it's removed: # Match the index to the working tree, and do a three-way. git diff-files --name-only | git update-index --remove --stdin && work=`git write-tree` && git read-tree $v --reset -u $new || exit git merge-recursive $old -- $new $work # Do not register the cleanly merged paths in the index yet. # this is not a real merge before committing, but just carrying # the working tree changes along. unmerged=`git ls-files -u` git read-tree $v --reset $new case "$unmerged" in '') ;; *) ( z40=0000000000000000000000000000000000000000 echo "$unmerged" | sed -e 's/^[0-7]* [0-9a-f]* /'"0 $z40 /" echo "$unmerged" ) | git update-index --index-info ;; esac Notice the last 'read-tree --reset' step. We restore worktree back to 'new' tree after worktree's messed up by merge-recursive. If there are staged changes before this whole command sequence is executed, they are lost because they are unlikely part of the 'new' tree to be restored. There is no easy way to fix this. Elijah may have something up his sleeves [1], but until then, check if there are staged changes and refuse to run and lose them. The user would need to do "git reset" to continue in this case. A note about the test update. 'checkout -m' in that test will fail because a deletion is staged. This 'checkout -m' was previously needed to verify quietness behavior of unpack-trees. But a different check has been put in place in the last patch. We can safely drop 'checkout -m' now.

2019-03-24read-tree: add --quietLibravatar Nguyễn Thái Ngọc Duy1-0/+1
read-tree is basically the front end of unpack-trees code and shoud expose all of its functionality (unless it's designed for internal use). This "opts.quiet" (formerly "opts.gently") was added for builtin/checkout.c but there is no reason why other read-tree users won't find this useful. The test that is updated to run 'read-tree --quiet' was added because unpack-trees was accidentally not being quiet [1] in 6a143aa2b2 (checkout -m: attempt merge when deletion of path was staged - 2014-08-12). Because checkout is the only "opts.quiet" user, there was no other way to test quiet behavior. But we can now test it directly. 6a143aa2b2 was manually reverted to verify that read-tree --quiet works correctly (i.e. test_must_be_empty fails). [1] the commit message there say "errors out instead of performing a merge" but I'm pretty sure the "performing a merge" happens anyway even before that commit. That line should say "errors out _in addition to_ performing a merge" Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-03-24unpack-trees: rename "gently" flag to "quiet"Libravatar Nguyễn Thái Ngọc Duy1-1/+1
The gently flag was added in 17e4642667 (Add flag to make unpack_trees() not print errors. - 2008-02-07) to suppress error messages. The name "gently" does not quite express that. Granted, being quiet is gentle but it could mean not performing some other actions. Rename the flag to "quiet" to be more on point.

2019-03-22commit: improve error message in "-a <paths>" caseLibravatar Nguyễn Thái Ngọc Duy1-1/+2
I did something stupid today and got $ git commit -a --fixup= @^ fatal: Paths with -a does not make sense. which didn't make any sense (at least for the first few seconds). Include the first path(spec) in the error message to help spot the problem quicker. Now it shows fatal: paths '@^ ...' with -a does not make sense which should ring some bell because @^ should clearly not be considered a path.

2019-03-21checkout.txt: note about losing staged changes with --mergeLibravatar Nguyễn Thái Ngọc Duy1-0/+9
If you have staged changes in path A and perform 'checkout --merge' (which could result in conflicts in a totally unrelated path B), changes in A will be gone. Which is unexpected. We are supposed to keep all changes, or kick and scream otherwise. This is the result of how --merge is implemented, from the very first day in 1be0659efc (checkout: merge local modifications while switching branches., 2006-01-12): 1. a merge is done, unmerged entries are collected 2. a hard switch to a new branch is done, then unmerged entries added back There is no trivial fix for this. Going with 3-way merge one file at a time loses rename detection. Going with 3-way merge by trees requires teaching the algorithm to pick up staged changes. And even if we detect staged changes with --merge and abort for safety, an option to continue --merge is very weird. Such an option would keep worktree changes, but drop staged changes. Because the problem has been with us since the introduction of --merge and everybody has been pretty happy (except Phillip, who found this problem), I'll just take a note here to acknowledge it and wait for merge wizards to come in and work their magic. There may be a way forward [1].

2019-03-21parse_opt_ref_sorting: always use with NONEG flagLibravatar Jeff King4-8/+4
The "--sort" parameter of for-each-ref, etc, does not handle negation, and instead returns an error to the parse-options code. But neither piece of code prints anything for the user, which may leave them confused: $ git for-each-ref --no-sort $ echo $? 129 As the comment in the callback function notes, this probably should clear the list, which would make it consistent with other list-like options (i.e., anything that uses OPT_STRING_LIST currently). Unfortunately that's a bit tricky due to the way the ref-filter code works. But in the meantime, let's at least make the error a little less confusing: - switch to using PARSE_OPT_NONEG in the option definition, which will cause the options code to produce a useful message - since this was cut-and-pasted to four different spots, let's define a single OPT_REF_SORT() macro that we can use everywhere - the callback can use BUG_ON_OPT_NEG() to make sure the correct flags are used (incidentally, this also satisfies -Wunused-parameters, since we're now looking at "unset") - expand the comment into a NEEDSWORK to make it clear that the direction is right, but the details need to be worked out Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
