2017-11-17add: introduce "--renormalize"Libravatar Torsten Bögershausen1-2/+26
Make it safer to normalize the line endings in a repository. Files that had been commited with CRLF will be commited with LF. The old way to normalize a repo was like this: # Make sure that there are not untracked files $ echo "* text=auto" >.gitattributes $ git read-tree --empty $ git add . $ git commit -m "Introduce end-of-line normalization" The user must make sure that there are no untracked files, otherwise they would have been added and tracked from now on. The new "add --renormalize" does not add untracked files: $ echo "* text=auto" >.gitattributes $ git add --renormalize . $ git commit -m "Introduce end-of-line normalization" Note that "git add --renormalize <pathspec>" is the short form for "git add -u --renormalize <pathspec>". While at it, document that the same renormalization may be needed, whenever a clean filter is added or changed.

2017-11-08reduce_heads: fix memory leaksLibravatar Martin Ågren5-5/+11
We currently have seven callers of `reduce_heads(foo)`. Six of them do not use the original list `foo` again, and actually, all six of those end up leaking it. Introduce and use `reduce_heads_replace(&foo)` as a leak-free version of `foo = reduce_heads(foo)` to fix several of these. Fix the remaining leaks using `free_commit_list()`. While we're here, document `reduce_heads()` and mark it as `extern`. Signed-off-by: Martin Ågren <martin.agren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-11-08builtin/merge-base: free commit listsLibravatar Martin Ågren1-18/+18
In several functions, we iterate through a commit list by assigning `result = result->next`. As a consequence, we lose the original pointer and eventually leak the list. Rewrite the loops so that we keep the original pointers, then call `free_commit_list()`. Various alternatives were considered: 1) Use `UNLEAK(result)` before the loop. Simple change, but not very pretty. These would definitely be new lows among our usages of UNLEAK. 2) Use `pop_commit()` when looping. Slightly less simple change, but it feels slightly preferable to first display the list, then free it. 3) As in this patch, but with `UNLEAK()` instead of freeing. We'd still go through all the trouble of refactoring the loop, and because it's not super-obvious that we're about to exit, let's just free the lists -- it probably doesn't affect the runtime much. In `handle_independent()` we can drop `result` while we're here and reuse the `revs`-variable instead. That matches several other users of `reduce_heads()`. The memory-leak that this hides will be addressed in the next commit. Signed-off-by: Martin Ågren <martin.agren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-11-02grep: take the read-lock when adding a submoduleLibravatar Martin Ågren1-0/+2
With --recurse-submodules, we add each submodule that we encounter to the list of alternate object databases. With threading, our changes to the list are not protected against races. Indeed, ThreadSanitizer reports a race when we call `add_to_alternates_memory()` around the same time that another thread is reading in the list through `read_sha1_file()`. Take the grep read-lock while adding the submodule. The lock is used to serialize uses of non-thread-safe parts of Git's API, including `read_sha1_file()`.

2017-11-01diff: add flag to indicate textconv was set via cmdlineLibravatar Brandon Williams1-1/+1
git-show is unique in that it wants to use textconv by default except for when it is showing blobs. When asked to show a blob, show doesn't want to use textconv unless the user explicitly requested that it be used by providing the command line flag '--textconv'. Currently this is done by using a parallel set of 'touched' flags which get set every time a particular flag is set or cleared. In a future patch we want to eliminate this parallel set of flags so instead of relying on if the textconv flag has been touched, add a new flag 'TEXTCONV_SET_VIA_CMDLINE' which is only set if textconv is set to true via the command line.

2017-10-31status: add option to show ignored files differentlyLibravatar Jameson Miller1-6/+25
Teach the status command more flexibility in how ignored files are reported. Currently, the reporting of ignored files and untracked files are linked. You cannot control how ignored files are reported independently of how untracked files are reported (i.e. `all` vs `normal`). This makes it impossible to show untracked files with the `all` option, but show ignored files with the `normal` option. This work 1) adds the ability to control the reporting of ignored files independently of untracked files and 2) introduces the concept of status reporting ignored paths that explicitly match an ignored pattern. There are 2 benefits to these changes: 1) if a consumer needs all untracked files but not all ignored files, there is a performance benefit to not scanning all contents of an ignored directory and 2) returning ignored files that explicitly match a path allow a consumer to make more informed decisions about when a status result might be stale. This commit implements --ignored=matching with --untracked-files=all. The following commit will implement --ignored=matching with --untracked=files=normal. As an example of where this flexibility could be useful is that our application (Visual Studio) runs the status command and presents the output. It shows all untracked files individually (e.g. using the '--untracked-files==all' option), and would like to know about which paths are ignored. It uses information about ignored paths to make decisions about when the status result might have changed. Additionally, many projects place build output into directories inside a repository's working directory (e.g. in "bin/" and "obj/" directories). Normal usage is to explicitly ignore these 2 directory names in the .gitignore file (rather than or in addition to the *.obj pattern).If an application could know that these directories are explicitly ignored, it could infer that all contents are ignored as well and make better informed decisions about files in these directories. It could infer that any changes under these paths would not affect the output of status. Additionally, there can be a significant performance benefit by avoiding scanning through ignored directories. When status is set to report matching ignored files, it has the following behavior. Ignored files and directories that explicitly match an exclude pattern are reported. If an ignored directory matches an exclude pattern, then the path of the directory is returned. If a directory does not match an exclude pattern, but all of its contents are ignored, then the contained files are reported instead of the directory.

2017-10-21remote: handle broken symrefsLibravatar Jeff King1-1/+1
It's possible for resolve_ref_unsafe() to return NULL with a REF_ISSYMREF flag if a symref points to a broken ref. In this case, the read_remote_branches() function will segfault passing the name to xstrdup(). This is hard to trigger in practice, since this function is used as a callback to for_each_ref(), which will skip broken refs in the first place (so it would have to be broken racily, or for us to see a transient filesystem error). If we see such a racy broken outcome let's treat it as "not a symref". This is exactly the same thing that would happen in the non-racy case (our function would not be called at all, as for_each_ref would skip the broken symref).

2017-10-21commit: check result of resolve_ref_unsafeLibravatar Andrey Okoshkin1-0/+2
Add check of the resolved HEAD reference while printing of a commit summary. resolve_ref_unsafe() may return NULL pointer if underlying calls of lstat() or open() fail in files_read_raw_ref(). Such situation can be caused by race: file becomes inaccessible to this moment. Signed-off-by: Andrey Okoshkin <a.okoshkin@samsung.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
