2019-07-29Merge branch 'sg/rebase-progress' into maintLibravatar Junio C Hamano1-0/+1

2019-06-24pager: add a helper function to clear the last line in the terminalLibravatar SZEDER Gábor1-0/+1
There are a couple of places where we want to clear the last line on the terminal, e.g. when a progress bar line is overwritten by a shorter line, then the end of that progress line would remain visible, unless we cover it up. In 'progress.c' we did this by always appending a fixed number of space characters to the next line (even if it was not shorter than the previous), but as it turned out that fixed number was not quite large enough, see the fix in 9f1fd84e15 (progress: clear previous progress update dynamically, 2019-04-12). From then on we've been keeping track of the length of the last displayed progress line and appending the appropriate number of space characters to the next line, if necessary, but, alas, this approach turned out to be error prone, see the fix in 1aed1a5f25 (progress: avoid empty line when breaking the progress line, 2019-05-19). The next patch in this series is about to fix a case where we don't clear the last line, and on occasion do end up with such garbage at the end of the line. It would be great if we could do that without the need to deal with that without meticulously computing the necessary number of space characters. So add a helper function to clear the last line on the terminal using an ANSI escape sequence, which has the advantage to clear the whole line no matter how wide it is, even after the terminal width changed. Such an escape sequence is not available on dumb terminals, though, so in that case fall back to simply print a whole terminal width (as reported by term_columns()) worth of space characters. In 'editor.c' launch_specified_editor() already used this ANSI escape sequence, so replace it with a call to this function.

2019-05-09Merge branch 'en/merge-directory-renames'Libravatar Junio C Hamano1-1/+1
"git merge-recursive" backend recently learned a new heuristics to infer file movement based on how other files in the same directory moved. As this is inherently less robust heuristics than the one based on the content similarity of the file itself (rather than based on what its neighbours are doing), it sometimes gives an outcome unexpected by the end users. This has been toned down to leave the renamed paths in higher/conflicted stages in the index so that the user can examine and confirm the result. * en/merge-directory-renames: merge-recursive: switch directory rename detection default merge-recursive: give callers of handle_content_merge() access to contents merge-recursive: track information associated with directory renames t6043: fix copied test description to match its purpose merge-recursive: switch from (oid,mode) pairs to a diff_filespec merge-recursive: cleanup handle_rename_* function signatures merge-recursive: track branch where rename occurred in rename struct merge-recursive: remove ren[12]_other fields from rename_conflict_info merge-recursive: shrink rename_conflict_info merge-recursive: move some struct declarations together merge-recursive: use 'ci' for rename_conflict_info variable name merge-recursive: rename locals 'o' and 'a' to 'obuf' and 'abuf' merge-recursive: rename diff_filespec 'one' to 'o' merge-recursive: rename merge_options argument from 'o' to 'opt' Use 'unsigned short' for mode, like diff_filespec does
2019-05-08fsmonitor: force a refresh after the index was discardedLibravatar Johannes Schindelin1-1/+2
With this change, the `index_state` struct becomes the new home for the flag that says whether the fsmonitor hook has been run, i.e. it is now per-index. It also gets re-set when the index is discarded, fixing the bug demonstrated by the "test_expect_failure" test added in the preceding commit. In that case fsmonitor-enabled Git would miss updates under certain circumstances, see that preceding commit for details.

2019-05-05*.[ch]: remove extern from function declarations using sedLibravatar Denton Liu1-2/+2
There has been a push to remove extern from function declarations. Finish the job by removing all instances of "extern" for function declarations in headers using sed. This was done by running the following on my system with sed 4.2.2: $ git ls-files \*.{c,h} | grep -v ^compat/ | xargs sed -i'' -e 's/^\(\s*\)extern \([^(]*([^*]\)/\1\2/' Files under `compat/` are intentionally excluded as some are directly copied from external sources and we should avoid churning them as much as possible. Then, leftover instances of extern were found by running $ git grep -w -C3 extern \*.{c,h} and manually checking the output. No other instances were found. Note that the regex used specifically excludes function variables which _should_ be left as extern. Not the most elegant way to do it but it gets the job done.

2019-03-07ident: don't require calling prepare_fallback_ident firstLibravatar Thomas Gummerer1-1/+0
In fd5a58477c ("ident: add the ability to provide a "fallback identity"", 2019-02-25) I made it a requirement to call prepare_fallback_ident as the first function in the ident API. However in stash we didn't actually end up following that. This leads to a BUG if user.email and user.name are set. It was not caught in the test suite because we only rely on environment variables for setting the user name and email instead of the config. Instead of making it a bug to call other functions in the ident API first, just return silently if the identity of a user was already set up.

2019-03-01setup: fix memory leaks with `struct repository_format`Libravatar Martin Ågren1-3/+28
After we set up a `struct repository_format`, it owns various pieces of allocated memory. We then either use those members, because we decide we want to use the "candidate" repository format, or we discard the candidate / scratch space. In the first case, we transfer ownership of the memory to a few global variables. In the latter case, we just silently drop the struct and end up leaking memory. Introduce an initialization macro `REPOSITORY_FORMAT_INIT` and a function `clear_repository_format()`, to be used on each side of `read_repository_format()`. To have a clear and simple memory ownership, let all users of `struct repository_format` duplicate the strings that they take from it, rather than stealing the pointers. Call `clear_...()` at the start of `read_...()` instead of just zeroing the struct, since we sometimes enter the function multiple times. Thus, it is important to initialize the struct before calling `read_...()`, so document that. It's also important because we might not even call `read_...()` before we call `clear_...()`, see, e.g., builtin/init-db.c. Teach `read_...()` to clear the struct on error, so that it is reset to a safe state, and document this. (In `setup_git_directory_gently()`, we look at `repo_fmt.hash_algo` even if `repo_fmt.version` is -1, which we weren't actually supposed to do per the API. After this commit, that's ok.) We inherit the existing code's combining "error" and "no version found". Both are signalled through `version == -1` and now both cause us to clear any partial configuration we have picked up. For "extensions.*", that's fine, since they require a positive version number. For "core.bare" and "core.worktree", we're already verifying that we have a non-negative version number before using them.

2019-02-22trace2: create new combined trace facilityLibravatar Jeff Hostetler1-0/+1
Create a new unified tracing facility for git. The eventual intent is to replace the current trace_printf* and trace_performance* routines with a unified set of git_trace2* routines. In addition to the usual printf-style API, trace2 provides higer-level event verbs with fixed-fields allowing structured data to be written. This makes post-processing and analysis easier for external tools. Trace2 defines 3 output targets. These are set using the environment variables "GIT_TR2", "GIT_TR2_PERF", and "GIT_TR2_EVENT". These may be set to "1" or to an absolute pathname (just like the current GIT_TRACE). * GIT_TR2 is intended to be a replacement for GIT_TRACE and logs command summary data. * GIT_TR2_PERF is intended as a replacement for GIT_TRACE_PERFORMANCE. It extends the output with columns for the command process, thread, repo, absolute and relative elapsed times. It reports events for child process start/stop, thread start/stop, and per-thread function nesting. * GIT_TR2_EVENT is a new structured format. It writes event data as a series of JSON records. Calls to trace2 functions log to any of the 3 output targets enabled without the need to call different trace_printf* or trace_performance* routines.

2019-02-04config: allow giving separate author and committer identsLibravatar William Hubbs1-2/+11
The author.email, author.name, committer.email and committer.name settings are analogous to the GIT_AUTHOR_* and GIT_COMMITTER_* environment variables, but for the git config system. This allows them to be set separately for each repository. Git supports setting different authorship and committer information with environment variables. However, environment variables are set in the shell, so if different authorship and committer information is needed for different repositories an external tool is required. This adds support to git config for author.email, author.name, committer.email and committer.name settings so this information can be set per repository. Also, it generalizes the fmt_ident function so it can handle author vs committer identification. Signed-off-by: William Hubbs <williamh@gentoo.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

By default, index compat macros are off from now on, because they could hide the_index dependency. Only those in builtin can use it. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-01-18Do not print 'dangling' for cat-file in case of ambiguityLibravatar David Turner1-1/+19
The return values -1 and -2 from get_oid could mean two different things, depending on whether they were from an enum returned by get_tree_entry_follow_symlinks, or from a different code path. This caused 'dangling' to be printed from a git cat-file in the case of an ambiguous (-2) result. Unify the results of get_oid* and get_tree_entry_follow_symlinks to be one common type, with unambiguous values.

2019-01-18Add 'human' date formatLibravatar Linus Torvalds1-0/+1
This adds --date=human, which skips the timezone if it matches the current time-zone, and doesn't print the whole date if that matches (ie skip printing year for dates that are "this year", but also skip the whole date itself if it's in the last few days and we can just say what weekday it was). For really recent dates (same day), use the relative date stamp, while for old dates (year doesn't match), don't bother with time and timezone. Also add 'auto' date mode, which defaults to human if we're using the pager. So you can do git config --add log.date auto and your "git log" commands will show the human-legible format unless you're scripting things. Note that this time format still shows the timezone for recent enough events (but not so recent that they show up as relative dates). You can combine it with the "-local" suffix to never show timezones for an even more simplified view. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Stephen P.

2019-01-17add: use separate ADD_CACHE_RENORMALIZE flagLibravatar Jeff King1-0/+1
Commit 9472935d81 (add: introduce "--renormalize", 2017-11-16) taught git-add to pass HASH_RENORMALIZE to add_to_index(), which then passes the flag along to index_path(). However, the flags taken by add_to_index() and the ones taken by index_path() are distinct namespaces. We cannot take HASH_* flags in add_to_index(), because they overlap with the ADD_CACHE_* flags we already take (in this case, HASH_RENORMALIZE conflicts with ADD_CACHE_IGNORE_ERRORS). We can solve this by adding a new ADD_CACHE_RENORMALIZE flag, and using it to set HASH_RENORMALIZE within add_to_index(). In order to make it clear that these two flags come from distinct sets, let's also change the name "newflags" in the function to "hash_flags".

2019-01-15cache: make oidcpy always copy GIT_MAX_RAWSZ bytesLibravatar brian m. carlson1-1/+1
There are some situations in which we want to store an object ID into struct object_id without the_hash_algo necessarily being set correctly. One such case is when cloning a repository, where we must read refs from the remote side without having a repository from which to read the preferred algorithm. In this cases, we may have the_hash_algo set to SHA-1, which is the default, but read refs into struct object_id that are SHA-256. When copying these values, we will want to copy them completely, not just the first 20 bytes. Consequently, make sure that oidcpy copies the maximum number of bytes at all times, regardless of the setting of the_hash_algo. Since oidcpy and hashcpy are no longer functionally identical, remove the Cocinelle object_id transformations that convert from one into the other.
