2019-07-30test-dir-iterator: do not assume errno valuesLibravatar Junio C Hamano2-3/+12
A few tests printed 'errno' as an integer and compared with hardcoded integers; this is obviously not portable. A two things to note are: - the string obtained by strerror() is not portable, and cannot be used for the purpose of these tests. - there unfortunately isn't a portable way to map error numbers to error names. As we only care about a few selected errors, just map the error number to the name before emitting for comparison. Reported-by: Randall S.

2019-07-23xdiff: clamp function context indices in post-imageLibravatar Jeff King1-0/+22
After finding a function line for --function-context in the pre-image, xdl_emit_diff() calculates the equivalent line in the post-image. It assumes that the lines between changes are the same on both sides. If the option --ignore-blank-lines was also given then this is not necessarily true. Clamp the calculation results for start and end of the function context to prevent out-of-bounds array accesses. Note that this _just_ fixes the case where our mismatch sends us off the beginning of the file. There are likely other cases where our assumption causes us to go to the wrong line within the file. Nobody has developed a test case yet, and the ultimate fix is likely more complicated than this patch. But this at least prevents a segfault in the meantime.

2019-07-19clean: show an error message when the path is too longLibravatar Johannes Schindelin1-0/+12
When `lstat()` failed, `git clean` would abort without an error message, leaving the user quite puzzled. In particular on Windows, where the default maximum path length is quite small (yet there are ways to circumvent that limit in many cases), it is very important that users be given an indication why their command failed because of too long paths when it did. This test case makes sure that a warning is issued that would have helped the user who reported this issue: https://github.com/git-for-windows/git/issues/521 Note that we temporarily set `core.longpaths = false` in the regression test; this ensures forward-compatibility with the `core.longpaths` feature that has not yet been upstreamed from Git for Windows.

2019-07-18rm: resolving by removal is not a warning-worthy eventLibravatar Junio C Hamano1-0/+13
When resolving a conflict on a path in favor of removing it, using "git rm" on it is the standard way to do so. The user however is greeted with a "needs merge" message during that operation: $ git merge side-branch $ edit conflicted-path-1 $ git add conflicted-path-1 $ git rm conflicted-path-2 conflicted-path-2: needs merge rm 'conflicted-path-2' The removal by "git rm" does get performed, but an uninitiated user may find it confusing, "needs merge? so I need to resolve conflict before being able to remove it???" The message is coming from "update-index --refresh" that is called internally to make sure "git rm" knows which paths are clean and which paths are dirty, in order to prevent removal of paths modified relative to the index without the "-f" option. We somehow ended up not squelching this message which seeped through to the UI surface. Use the same mechanism used by "git commit", "git describe", etc. to squelch the message.

2019-07-16stash: fix handling removed files with --keep-indexLibravatar Thomas Gummerer1-0/+7
git stash push --keep-index is supposed to keep all changes that have been added to the index, both in the index and on disk. Currently this doesn't behave correctly when a file is removed from the index. Instead of keeping it deleted on disk, --keep-index currently restores the file. Fix that behaviour by using 'git checkout' in no-overlay mode which can faithfully restore the index and working tree. This also simplifies the code. Note that this will overwrite untracked files if the untracked file has the same name as a file that has been deleted in the index.

2019-07-16mingw: support spawning programs containing spaces in their namesLibravatar Johannes Schindelin1-0/+6
On some older Windows versions (e.g. Windows 7), the CreateProcessW() function does not really support spaces in its first argument, lpApplicationName. But it supports passing NULL as lpApplicationName, which makes it figure out the application from the (possibly quoted) first argument of lpCommandLine. Let's use that trick (if we are certain that the first argument matches the executable's path) to support launching programs whose path contains spaces.

2019-07-12transport-helper: enforce atomic in push_refs_with_pushLibravatar Emily Shaffer1-0/+49
Teach transport-helper how to notice if skipping a ref during push would violate atomicity on the client side. We notice that a ref would be rejected, and choose not to send it, but don't notice that if the client has asked for --atomic we are violating atomicity if all the other pushes we are sending would succeed. Asking the server end to uphold atomicity wouldn't work here as the server doesn't have any idea that we tried to update a ref that's broken. The added test-case is a succinct way to reproduce this issue that fails today. The same steps work fine when we aren't using a transport-helper to get to the upstream, i.e. when we've added a local repository as a remote: git remote add ~/upstream upstream Signed-off-by: Emily Shaffer <emilyshaffer@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Add the section headers/hunk headers we introduced in the previous commits to the outer diff's hunk headers. This makes it easier to understand which change we are actually looking at. For example an outer hunk header might now look like: @@ Documentation/config/interactive.txt while previously it would have only been @@ which doesn't give a lot of context for the change that follows. For completeness also add section headers for the commit metadata and the commit message, although they are arguably less important.

2019-07-11range-diff: add filename to inner diffLibravatar Thomas Gummerer1-6/+10
In a range-diff it's not always clear which file a certain funcname of the inner diff belongs to, because the diff header (or section header as added in a previous commit) is not always visible in the range-diff. Add the filename to the inner diffs header, so it's always visible to users. This also allows us to add the filename + the funcname to the outer diffs hunk headers using a custom userdiff pattern, which will be done in the next commit.

2019-07-11range-diff: add section header instead of diff headerLibravatar Thomas Gummerer2-10/+165
Currently range-diff keeps the diff header of the inner diff intact (apart from stripping lines starting with index). This diff header is somewhat useful, especially when files get different names in different ranges. However there is no real need to keep the whole diff header for that. The main reason we currently do that is probably because it is easy to do. Introduce a new range diff hunk header, that's enclosed by "##", similar to how line numbers in diff hunks are enclosed by "@@", and give human readable information of what exactly happened to the file, including the file name. This improves the readability of the range-diff by giving more concise information to the users. For example if a file was renamed in one iteration, but not in another, the diff of the headers would be quite noisy. However the diff of a single line is concise and should be easier to understand. Additionally, this allows us to add these range diff section headers to the outer diffs hunk headers using a custom userdiff pattern, which should help making the range-diff more readable.

The line count in the outer diff's hunk headers of a range diff is not all that interesting. It merely shows how far along the inner diff are on both sides. That number is of no use for human readers, and range-diffs are not meant to be machine readable. In a subsequent commit we're going to add some more contextual information such as the filename corresponding to the diff to the hunk headers. Remove the unnecessary information, and just keep the "@@" to indicate that a new hunk of the outer diff is starting.

2019-07-11range-diff: don't remove funcname from inner diffLibravatar Thomas Gummerer1-3/+3
When postprocessing the inner diff in range-diff, we currently replace the whole hunk header line with just "@@". This matches how 'git tbdiff' used to handle hunk headers as well. Most likely this is being done because line numbers in the hunk header are not relevant without other changes. They can for example easily change if a range is rebased, and lines are added/removed before a change that we actually care about in our ranges. However it can still be useful to have the function name that 'git diff' extracts as additional context for the change. Note that it is not guaranteed that the hunk header actually shows up in the range-diff, and this change only aims to improve the case where a hunk header would already be included in the final output.

Make the copy_or_link_directory function no longer skip hidden directories. This function, used to copy .git/objects, currently skips all hidden directories but not hidden files, which is an odd behaviour.

Currently possible flags are: - DIR_ITERATOR_PEDANTIC, which makes dir_iterator_advance abort immediately in the case of an error, instead of keep looking for the next valid entry; - DIR_ITERATOR_FOLLOW_SYMLINKS, which makes the iterator follow symlinks and include linked directories' contents in the iteration.

2019-07-11dir-iterator: refactor state machine modelLibravatar Matheus Tavares2-0/+18
dir_iterator_advance() is a large function with two nested loops. Let's improve its readability factoring out three functions and simplifying its mechanics. The refactored model will no longer depend on level.initialized and level.dir_state to keep track of the iteration state and will perform on a single loop. Also, dir_iterator_begin() currently does not check if the given string represents a valid directory path. Since the refactored model will have to stat() the given path at initialization, let's also check for this kind of error and make dir_iterator_begin() return NULL, on failures, with errno appropriately set. And add tests for this new behavior. Improve documentation at dir-iteration.h and code comments at dir-iterator.c to reflect the changes and eliminate possible ambiguities. Finally, adjust refs/files-backend.c to check for now possible dir_iterator_begin() failures.

2019-07-11clone: better handle symlinked files at .git/objects/Libravatar Matheus Tavares1-7/+20
There is currently an odd behaviour when locally cloning a repository with symlinks at .git/objects: using --no-hardlinks all symlinks are dereferenced but without it, Git will try to hardlink the files with the link() function, which has an OS-specific behaviour on symlinks. On OSX and NetBSD, it creates a hardlink to the file pointed by the symlink whilst on GNU/Linux, it creates a hardlink to the symlink itself. On Manjaro GNU/Linux: $ touch a $ ln -s a b $ link b c $ ls -li a b c 155 [...] a 156 [...] b -> a 156 [...] c -> a But on NetBSD: $ ls -li a b c 2609160 [...] a 2609164 [...] b -> a 2609160 [...] c It's not good to have the result of a local clone to be OS-dependent and besides that, the current behaviour on GNU/Linux may result in broken symlinks. So let's standardize this by making the hardlinks always point to dereferenced paths, instead of the symlinks themselves. Also, add tests for symlinked files at .git/objects/. Note: Git won't create symlinks at .git/objects itself, but it's better to handle this case and be friendly with users who manually create them.

2019-07-11clone: test for our behavior on odd objects/* contentLibravatar Ævar Arnfjörð Bjarmason1-0/+111
Add tests for what happens when we perform a local clone on a repo containing odd files at .git/object directory, such as symlinks to other dirs, or unknown files. I'm bending over backwards here to avoid a SHA-1 dependency. See [1] for an earlier and simpler version that hardcoded SHA-1s. This behavior has been the same for a *long* time, but hasn't been tested for. There's a good post-hoc argument to be made for copying over unknown things, e.g. I'd like a git version that doesn't know about the commit-graph to copy it under "clone --local" so a newer git version can make use of it. In follow-up commits we'll look at changing some of this behavior, but for now, let's just assert it as-is so we'll notice what we'll change later. 1. https://public-inbox.org/git/20190226002625.13022-5-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> [matheus.bernardino: improved and split tests in more than one patch] Helped-by: Matheus Tavares <matheus.bernardino@usp.br> Signed-off-by: Matheus Tavares <matheus.bernardino@usp.br> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-07-09Merge branch 'ds/fetch-disable-force-notice'Libravatar Junio C Hamano1-0/+23
"git fetch" and "git pull" reports when a fetch results in non-fast-forward updates to let the user notice unusual situation. The commands learned "--no-shown-forced-updates" option to disable this safety feature. * ds/fetch-disable-force-notice: pull: add --[no-]show-forced-updates passthrough fetch: warn about forced updates in branch listing fetch: add --[no-]show-forced-updates argument
2019-07-09Merge branch 'jh/status-aheadbehind'Libravatar Junio C Hamano2-0/+39
"git status" can be told a non-standard default value for the "--[no-]ahead-behind" option with a new configuration variable status.aheadBehind. * jh/status-aheadbehind: status: ignore status.aheadbehind in porcelain formats status: warn when a/b calculation takes too long status: add status.aheadbehind setting
