2019-04-02checkout: inform the user when removing branch stateLibravatar Nguyễn Thái Ngọc Duy1-1/+1
After a successful switch, if a merge, cherry-pick or revert is ongoing, it is canceled. This behavior has been with us from the very early beginning, soon after git-merge was created but never actually documented [1]. It may be a good idea to be transparent and tell the user if some operation is canceled. I consider this a better way of telling the user than just adding a sentence or two in git-checkout.txt, which will be mostly ignored anyway. PS. Originally I wanted to print more details like warning: cancelling an in-progress merge from <SHA-1> which may allow some level of undo if the user wants to. But that seems a lot more work. Perhaps it can be improved later if people still want that. [1] ... and I will try not to argue whether it is a sensible behavior. There is some more discussion here if people are interested: CACsJy8Axa5WsLSjiscjnxVK6jQHkfs-gH959=YtUvQkWriAk5w@mail.gmail.com Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Add a post-index-change hook that is invoked after the index is written in do_write_locked_index(). This hook is meant primarily for notification, and cannot affect the outcome of git commands that trigger the index write. The hook is passed a flag to indicate whether the working directory was updated or not and a flag indicating if a skip-worktree bit could have changed. These flags enable the hook to optimize its response to the index change notification. Signed-off-by: Ben Peart <benpeart@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-10-24reset: don't compute unstaged changes after reset when --quietLibravatar Ben Peart1-1/+1
When git reset is run with the --quiet flag, don't bother finding any additional unstaged changes as they won't be output anyway. This speeds up the git reset command by avoiding having to lstat() every file looking for changes that aren't going to be reported anyway. The savings can be significant. In a repo on Windows with 200K files "git reset" drops from 7.16 seconds to 0.32 seconds for a savings of 96%.

2018-08-02Merge branch 'jm/cache-entry-from-mem-pool'Libravatar Junio C Hamano1-1/+1
For a large tree, the index needs to hold many cache entries allocated on heap. These cache entries are now allocated out of a dedicated memory pool to amortize malloc(3) overhead. * jm/cache-entry-from-mem-pool: block alloc: add validations around cache_entry lifecyle block alloc: allocate cache entries from mem_pool mem-pool: fill out functionality mem-pool: add life cycle management functions mem-pool: only search head block for available space block alloc: add lifecycle APIs for cache_entry structs read-cache: teach make_cache_entry to take object_id read-cache: teach refresh_cache_entry to take istate
2018-07-03block alloc: add lifecycle APIs for cache_entry structsLibravatar Jameson Miller1-1/+1
It has been observed that the time spent loading an index with a large number of entries is partly dominated by malloc() calls. This change is in preparation for using memory pools to reduce the number of malloc() calls made to allocate cahce entries when loading an index. Add an API to allocate and discard cache entries, abstracting the details of managing the memory backing the cache entries. This commit does actually change how memory is managed - this will be done in a later commit in the series. This change makes the distinction between cache entries that are associated with an index and cache entries that are not associated with an index. A main use of cache entries is with an index, and we can optimize the memory management around this. We still have other cases where a cache entry is not persisted with an index, and so we need to handle the "transient" use case as well. To keep the congnitive overhead of managing the cache entries, there will only be a single discard function. This means there must be enough information kept with the cache entry so that we know how to discard them. A summary of the main functions in the API is: make_cache_entry: create cache entry for use in an index. Uses specified parameters to populate cache_entry fields. make_empty_cache_entry: Create an empty cache entry for use in an index. Returns cache entry with empty fields. make_transient_cache_entry: create cache entry that is not used in an index. Uses specified parameters to populate cache_entry fields. make_empty_transient_cache_entry: create cache entry that is not used in an index. Returns cache entry with empty fields. discard_cache_entry: A single function that knows how to discard a cache entry regardless of how it was allocated.

2018-02-15Merge branch 'tg/reset-hard-show-head-with-pretty'Libravatar Junio C Hamano1-18/+10
The way "git reset --hard" reports the commit the updated HEAD points at is made consistent with the way how the commit title is generated by the other parts of the system. This matters when the title is spread across physically multiple lines. * tg/reset-hard-show-head-with-pretty: reset --hard: make use of the pretty machinery
2018-02-02reset --hard: make use of the pretty machineryLibravatar Thomas Gummerer1-18/+10
reset --hard currently uses its own logic for printing the first line of the commit message in its output. Instead of just using the first line, use the pretty machinery to create the output. In addition to the easier to follow code, this makes the output more consistent with other commands that print the title of the commit, such as 'git commit --oneline' or 'git checkout', which both use 'pp_commit_easy()' with the CMIT_FMT_ONELINE modifier. It is a slight change of the output if the second line of the commit message is not a blank line, i.e. if the commit message is foo bar previously we would print "HEAD is now at 000000 foo", while after this change we print "HEAD is now at 000000 foo bar", same as 'git log --oneline' shows "000000 foo bar". So this does make the output more consistent with other commands, and 'reset' is a porcelain command, so nobody should be parsing the output in scripts. The current behaviour dates back to 0e5a7faa3a ("Make "git reset" a builtin.", 2007-09-11), so I assume (without digging into the old codebase too much) that the logic was implemented because there was no convenience function such as 'pp_commit_easy' that would do this already.

We read the tree objects with fill_tree_descriptor(), but never actually free the resulting buffers, causing a memory leak.

2017-09-06reset: make tree counting less confusingLibravatar Jeff King1-3/+5
Depending on whether we're in --keep mode, git-reset may feed one or two trees to unpack_trees(). We start a counter at "1" and then increment it to "2" only for the two-tree case. But that means we must always subtract one to find the correct array slot to fill with each descriptor. Instead, let's start at "0" and just increment our counter after adding each tree. This skips the extra subtraction, and will make things much easier when we start to actually free our tree buffers. While we're at it, let's make the first allocation use the slot at "desc + nr", too, even though we know "nr" is 0 at that point. It makes the two fill_tree_descriptor() calls consistent (always "desc + nr", followed by always incrementing "nr").

2017-09-06stop leaking lock structs in some simple casesLibravatar Jeff King1-3/+3
Now that it's safe to declare a "struct lock_file" on the stack, we can do so (and avoid an intentional leak). These leaks were found by running t0000 and t0001 under valgrind (though certainly other similar leaks exist and just don't happen to be exercised by those tests). Initializing the lock_file's inner tempfile with NULL is not strictly necessary in these cases, but it's a good practice to model. It means that if we were to call a function like rollback_lock_file() on a lock that was never taken in the first place, it becomes a quiet noop (rather than undefined behavior). Likewise, it's always safe to rollback_lock_file() on a file that has already been committed or deleted, since that operation is a noop on an inactive lockfile (and that's why the case in config.c can drop the "if (lock)" check as we move away from using a pointer).

2017-06-24Merge branch 'bw/config-h'Libravatar Junio C Hamano1-0/+1
Fix configuration codepath to pay proper attention to commondir that is used in multi-worktree situation, and isolate config API into its own header file. * bw/config-h: config: don't implicitly use gitdir or commondir config: respect commondir setup: teach discover_git_directory to respect the commondir config: don't include config.h by default config: remove git_config_iter config: create config.h
2017-06-15config: don't include config.h by defaultLibravatar Brandon Williams1-0/+1
Stop including config.h by default in cache.h. Instead only include config.h in those files which require use of the config system. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Many commands learned to pay attention to submodule.recurse configuration. * sb/submodule-blanket-recursive: builtin/fetch.c: respect 'submodule.recurse' option builtin/push.c: respect 'submodule.recurse' option builtin/grep.c: respect 'submodule.recurse' option Introduce 'submodule.recurse' option for worktree manipulators submodule loading: separate code path for .gitmodules and config overlay reset/checkout/read-tree: unify config callback for submodule recursion submodule test invocation: only pass additional arguments submodule recursing: do not write a config variable twice
2017-06-01Introduce 'submodule.recurse' option for worktree manipulatorsLibravatar Stefan Beller1-1/+9
Any command that understands '--recurse-submodules' can have its default changed to true, by setting the new 'submodule.recurse' option. This patch includes read-tree/checkout/reset for working tree manipulating commands. Later patches will cover other commands.

2017-05-30reset/checkout/read-tree: unify config callback for submodule recursionLibravatar Stefan Beller1-25/+2
The callback function is essentially duplicated 3 times. Remove all of them and offer a new callback function, that lives in submodule.c By putting the callback function there, we no longer need the function 'set_config_update_recurse_submodules', nor duplicate the global variable in each builtin as well as submodule.c In the three builtins we have different 2 ways how to load the .gitmodules and config file, which are slightly different. git-checkout has to load the submodule config all the time due to 23b4c7bcc5 (checkout: Use submodule.*.ignore settings from .git/config and .gitmodules, 2010-08-28) git-reset and git-read-tree do not respect these diff settings, so loading the submodule configuration is optional. Also put that into submodule.c for code deduplication. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-05-30submodule recursing: do not write a config variable twiceLibravatar Stefan Beller1-1/+1
The command line option for '--recurse-submodules' is implemented using an OPTION_CALLBACK, which takes both the callback (that sets the file static global variable) as well as passes the same file static global variable to the option parsing machinery to assign it. This is fixed in this commit by passing NULL as the variable. The callback sets it instead Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
