2021-09-27Change unpack_trees' 'reset' flag into an enumLibravatar Elijah Newren1-2/+7
Traditionally, unpack_trees_options->reset was used to signal that it was okay to delete any untracked files in the way. This was used by `git read-tree --reset`, but then started appearing in other places as well. However, many of the other uses should not be deleting untracked files in the way. Change this value to an enum so that a value of 1 (i.e. "true") can be split into two: UNPACK_RESET_PROTECT_UNTRACKED, UNPACK_RESET_OVERWRITE_UNTRACKED In order to catch accidental misuses (i.e. where folks call it the way they traditionally used to), define the special enum value of UNPACK_RESET_INVALID = 1 which will trigger a BUG(). Modify existing callers so that read-tree --reset reset --hard checkout --force continue using the UNPACK_RESET_OVERWRITE_UNTRACKED logic, while other callers, including am checkout without --force stash (though currently dead code; reset always had a value of 0) numerous callers from rebase/sequencer to reset_head() will use the new UNPACK_RESET_PROTECT_UNTRACKED value. Also, note that it has been reported that 'git checkout <treeish> <pathspec>' currently also allows overwriting untracked files[1]. That case should also be fixed, but it does not use unpack_trees() and thus is outside the scope of the current changes.

2021-09-27Remove ignored files by default when they are in the wayLibravatar Elijah Newren1-2/+1
Change several commands to remove ignored files by default when they are in the way. Since some commands (checkout, merge) take a --no-overwrite-ignore option to allow the user to configure this, and it may make sense to add that option to more commands (and in the case of merge, actually plumb that configuration option through to more of the backends than just the fast-forwarding special case), add little comments about where such flags would be used. Incidentally, this fixes a test failure in t7112. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2021-09-27unpack-trees: introduce preserve_ignored to unpack_trees_optionsLibravatar Elijah Newren1-0/+2
Currently, every caller of unpack_trees() that wants to ensure ignored files are overwritten by default needs to: * allocate unpack_trees_options.dir * flip the DIR_SHOW_IGNORED flag in unpack_trees_options.dir->flags * call setup_standard_excludes AND then after the call to unpack_trees() needs to * call dir_clear() * deallocate unpack_trees_options.dir That's a fair amount of boilerplate, and every caller uses identical code. Make this easier by instead introducing a new boolean value where the default value (0) does what we want so that new callers of unpack_trees() automatically get the appropriate behavior. And move all the handling of unpack_trees_options.dir into unpack_trees() itself. While preserve_ignored = 0 is the behavior we feel is the appropriate default, we defer fixing commands to use the appropriate default until a later commit. So, this commit introduces several locations where we manually set preserve_ignored=1. This makes it clear where code paths were previously preserving ignored files when they should not have been; a future commit will flip these to instead use a value of 0 to get the behavior we want.

In c4a09cc9ccb (Merge branch 'hw/advise-ng', 2020-03-25), a new API for accessing advice variables was introduced and deprecated `advice_config` in favor of a new array, `advice_setting`. This patch ports all but two uses which read the status of the global `advice_` variables over to the new `advice_enabled` API.

2020-09-02wt-status: tolerate dangling marksLibravatar Jonathan Tan1-1/+1
When a user checks out the upstream branch of HEAD, the upstream branch not being a local branch, and then runs "git status", like this: git clone $URL client cd client git checkout @{u} git status no status is printed, but instead an error message: fatal: HEAD does not point to a branch (This error message when running "git branch" persists even after checking out other things - it only stops after checking out a branch.) This is because "git status" reads the reflog when determining the "HEAD detached" message, and thus attempts to DWIM "@{u}", but that doesn't work because HEAD no longer points to a branch. Therefore, when calculating the status of a worktree, tolerate dangling marks. This is done by adding an additional parameter to dwim_ref() and repo_dwim_ref().

2020-04-28Use OPT_CALLBACK and OPT_CALLBACK_FLibravatar Denton Liu1-2/+2
In the codebase, there are many options which use OPTION_CALLBACK in a plain ol' struct definition. However, we have the OPT_CALLBACK and OPT_CALLBACK_F macros which are meant to abstract these plain struct definitions away. These macros are useful as they semantically signal to developers that these are just normal callback option with nothing fancy happening. Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or OPT_CALLBACK_F where applicable. The heavy lifting was done using the following (disgusting) shell script: #!/bin/sh do_replacement () { tr '\n' '\r' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\s*0,\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK(\1,\2,\3,\4,\5,\6)/g' | sed -e 's/{\s*OPTION_CALLBACK,\s*\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\([^,]*\),\(\s*[^[:space:]}]*\)\s*}/OPT_CALLBACK_F(\1,\2,\3,\4,\5,\6,\7)/g' | tr '\r' '\n' } for f in $(git ls-files \*.c) do do_replacement <"$f" >"$f.tmp" mv "$f.tmp" "$f" done The result was manually inspected and then reformatted to match the style of the surrounding code. Finally, using `git grep OPTION_CALLBACK \*.c`, leftover results which were not handled by the script were manually transformed.

Since 2f328c3d ("reset $sha1 $pathspec: require $sha1 only to be treeish", 2013-01-14), we allowed "git reset $object -- $path" to reset individual paths that match the pathspec to take the blob from a tree object, not necessarily a commit, while the form to reset the tip of the current branch to some other commit still must be given a commit. Like resetting with paths, "git reset --patch" does not update HEAD, and need not require a commit. The path-filtered form, "git reset --patch $object -- $pathspec", has accepted a tree-ish since 2f328c3d. "git reset --patch" is documented as accepting a <tree-ish> since bf44142f ("reset: update documentation to require only tree-ish with paths", 2013-01-16). Documentation changes are not required.

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.

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.

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.

2017-09-19Merge branch 'jk/leak-checkers'Libravatar Junio C Hamano1-6/+16
Many of our programs consider that it is OK to release dynamic storage that is used throughout the life of the program by simply exiting, but this makes it harder to leak detection tools to avoid reporting false positives. Plug many existing leaks and introduce a mechanism for developers to mark that the region of memory pointed by a pointer is not lost/leaking to help these tools. * jk/leak-checkers: add UNLEAK annotation for reducing leak false positives set_git_dir: handle feeding gitdir to itself repository: free fields before overwriting them reset: free allocated tree buffers reset: make tree counting less confusing config: plug user_config leak update-index: fix cache entry leak in add_one_file() add: free leaked pathspec after add_files_to_cache() test-lib: set LSAN_OPTIONS to abort by default test-lib: --valgrind should not override --verbose-log
2017-09-06reset: free allocated tree buffersLibravatar Jeff King1-5/+13
We read the tree objects with fill_tree_descriptor(), but never actually free the resulting buffers, causing a memory leak. This isn't a huge deal because we call this code at most twice per program invocation. But it does potentially double our heap usage if you have large root trees. Let's free the trees before returning. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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).
