* [PATCHv7 4/6] worktree: have a function to check if worktrees are in use
From: Stefan Beller @ 2016-12-08 21:03 UTC (permalink / raw)
To: bmwill; +Cc: git, pclouds, gitster, Stefan Beller
In-Reply-To: <20161208210329.12919-1-sbeller@google.com>
In a later patch we want to move around the the git directory of
a submodule. Both submodules as well as worktrees are involved in
placing git directories at unusual places, so their functionality
may collide. To react appropriately to situations where worktrees
in submodules are in use, offer a new function to query the
a submodule if it uses the worktree feature.
This can be done cheaply (both in new code to write as well as run time)
by obtaining the list of worktrees based off that submodules git
directory. However as we have loaded the variables for the current
repository, the values in the submodule worktree
can be wrong, e.g.
* core.ignorecase may differ between these two repositories
* the ref resolution is broken (refs/heads/branch in the submodule
resolves to the sha1 value of the `branch` in the current repository
that may not exist or have another sha1)

That function was primarily used by submodule code, but the function
itself is not inherently about submodules. In the next patch we'll
introduce relocate_git_dir, which can be used by worktrees as well,
so find a neutral middle ground in dir.h.

* [PATCHv7 2/6] submodule helper: support super prefix

In-Reply-To: <20161208210329.12919-1-sbeller@google.com>
Just like main commands in Git, the submodule helper needs
access to the superproject prefix. Enable this in the git.c
but have its own fuse in the helper code by having a flag to
turn on the super prefix.

* [PATCHv7 1/6] submodule: use absolute path for computing relative path connecting
From: Stefan Beller @ 2016-12-08 21:03 UTC (permalink / raw)
To: bmwill; +Cc: git, pclouds, gitster, Stefan Beller
In-Reply-To: <20161208210329.12919-1-sbeller@google.com>
The current caller of connect_work_tree_and_git_dir passes
an absolute path for the `git_dir` parameter. In the future patch
we will also pass in relative path for `git_dir`. Extend the functionality
of connect_work_tree_and_git_dir to take relative paths for parameters.
We could work around this in the future patch by computing the absolute
path for the git_dir in the calling site, however accepting relative
paths for either parameter makes the API for this function much harder
to misuse.

* [PATCHv7 0/6] submodule absorbgitdirs
From: Stefan Beller @ 2016-12-08 21:03 UTC (permalink / raw)
To: bmwill; +Cc: git, pclouds, gitster, Stefan Beller
v7:
* do not expose submodule_get_worktrees. The values may be wrong internally,
but for our purpose we do not care about the actual values, only the count.
Document the wrong values!
* more strings are _(marked up)
* renamed variables in connect_work_tree_and_git_dir
* unsigned instead of int for options in the submodule helper.
*
v6:
* renamed embedgitdirs to absorbgitdirs embedding may be interpreted as
embedding the git dir into the working directory, whereas absorbing sounds
more like the submodule is absorbed by the superproject, making the
submodule less independent
* Worktrees API offer uses_worktrees(void) and submodule_uses_worktree(path).
* moved the printing to stderr and one layer up (out of the pure
relocate_git_dir function).
* connect_... is in dir.h now.
v5:
* Add another layer of abstraction, i.e. the relocate_git_dir is only about
moving a git dir of one repository. The submodule specific stuff (e.g.
recursion into nested submodules) is in submodule.{c,h}
This was motivated by reviews on the series of checkout aware of submodules
building on top of this series, as we want to directly call the embed-git-dirs
function without the overhead of spawning a child process.
v4:
* rebuilt on top of nd/worktree-list-fixup
* fix and test behavior for un-init submodules (don't crash, rather do nothing)
* incorporated a "static" as pointed out by Ramsay
* use internal functions instead of duplicating code in worktree.c
(use get_common_dir_noenv for the submodule to actually get the common dir)
* fixed a memory leak in relocate_gitdir
v3:
* have a slightly more generic function "relocate_gitdir".
The recursion is strictly related to submodules, though.
* bail out if a submodule is using worktrees.
This also lays the groundwork for later doing the proper thing,
as worktree.h offers a function `get_submodule_worktrees(path)`
* nit by duy: use git_path instead of git_common_dir
v2:
* fixed commit message for patch:
"submodule: use absolute path for computing relative path connecting"
* a new patch "submodule helper: support super prefix"
* redid the final patch with more tests and fixing bugs along the way
* "test-lib-functions.sh: teach test_commit -C <dir>" unchanged
v1:
The discussion of the submodule checkout series revealed to me that a command
is needed to move the git directory from the submodules working tree to be
embedded into the superprojects git directory.
So I wrote the code to intern the submodules git dir into the superproject,
but whilst writing the code I realized this could be valueable for our use
in testing too. So I exposed it via the submodule--helper. But as the
submodule helper ought to be just an internal API, we could also
offer it via the proper submodule command.
The command as it is has little value to the end user for now, but
breaking it out of the submodule checkout series hopefully makes review easier.
Thanks,
Stefan

Its effect is exactly the same. just plain code duplication. I assume that
is okay here as it really is only one constant for now. Maybe we can
refactor that to
be defined in a header file (but which? There is no such thing as a git.h, where
I'd expect to put it.)

* Feature request: read git config from parent directory
From: Dominique Dumont @ 2016-12-08 19:49 UTC (permalink / raw)
To: git
Hello
I use the same machine for work and open-source contribution. In both cases, I
deal with a lot of repositories. Depending on whether I commit for work or
open-source activities, I must use a different mail address. I used to setup
work address for each work repo in git local config, but this is no longer
practical.
Since I use different directories for work and open-source, would it be
possible for git to read irs config also from parent directories ? I.e. setup
git to read config from ./.git/config then ../.gitconfig, ../../gitconfig until
global ~/.gitconfig.
All the best

I am interested in the submodule case however, where we already return NULL
e.g. when the submodule git dir cannot be found. Actually that would
work out fine
as well:
/* NOTE on accuracy of result, hence not exposed. */
static worktree **submodule_get_worktrees(const char *path, unsigned flags)
..
int submodule_uses_worktrees(const char *path)
{
struct worktree **worktrees = submodule_get_worktrees(path,
WT_LINKED_ONLY);
int retval = worktrees != NULL;
free_worktrees(worktrees);
return retval;
}
Thanks for that inspiration!

I totally agree with that (and I don't know why I used "curr", probably
just because it looked consistent and good...).
However:
> -static void update_curr_file()
> +static void update_current_file(void)
This function name could lead to the impression that there is some
current file (defined by a global state or whatever) that is updated.
So I'd rather rename the *file* to one of
* sequencer/abort-safety (consistent to am, describes its purpose)
* sequencer/safety (shorter, still describes the purpose)
* sequencer/current-head (describes what it contains)
* sequencer/last (a four-letter word, not totally unambiguous though)

That's usually a matter of taste that I sometimes also discuss with
colleagues in other projects... However, for the git test suite with its
"known breakage" behavior, your recommendation is surely the best way to
do it (aside from introducing the test and the fix in one commit... but
that does not show in the history that there actually was that breakage)

In-Reply-To: <1481223550-65277-1-git-send-email-bmwill@google.com>
Now that all callers of the old 'get_pathspec' interface have been
migrated to use the new pathspec struct interface it can be removed
from the codebase.
Since there are no more users of the '_raw' field in the pathspec struct
it can also be removed. This patch also removes the old functionality
of modifying the const char **argv array that was passed into
parse_pathspec. Instead the constructed 'match' string (which is a
pathspec element with the prefix prepended) is only stored in its
corresponding pathspec_item entry.

In-Reply-To: <1481223550-65277-1-git-send-email-bmwill@google.com>
For better clarity, always show the mnemonic and name of the unsupported
magic being used. This lets users have a more clear understanding of
what magic feature isn't supported. And if they supplied a mnemonic,
the user will be told what its corresponding name is which will allow
them to more easily search the man pages for that magic type.
This also avoids passing an extra parameter around the pathspec
initialization code.

In-Reply-To: <1481223550-65277-1-git-send-email-bmwill@google.com>
A few small changes to improve readability. This is done by grouping related
assignments, adding blank lines, ensuring lines are <80 characters, and
adding additional comments.

* [PATCH v2 13/16] pathspec: create parse_element_magic helper
From: Brandon Williams @ 2016-12-08 18:59 UTC (permalink / raw)

In-Reply-To: <1481223550-65277-1-git-send-email-bmwill@google.com>
Factor out the logic responsible for the magic in a pathspec element
into its own function.
Also avoid calling into the parsing functions when
`PATHSPEC_LITERAL_PATH` is specified since it causes magic to be
ignored and all paths to be treated as literals.

function. As well as hoist the prefix check logic outside of the inner

"prefix:".

* [PATCH v2 09/16] pathspec: simpler logic to prefix original pathspec elements
From: Brandon Williams @ 2016-12-08 18:59 UTC (permalink / raw)
To: git; +Cc: Brandon Williams, sbeller, pclouds, gitster
In-Reply-To: <1481223550-65277-1-git-send-email-bmwill@google.com>
The logic used to prefix an original pathspec element with 'prefix'
magic is more general purpose and can be used for more than just short
magic. Remove the extra code paths and rename 'prefix_short_magic' to
'prefix_magic' to better indicate that it can be used in more general
situations.
Also, slightly change the logic which decides when to prefix the
original element in order to prevent a pathspec of "." from getting
converted to "" (empty string).

* [PATCH v2 06/16] pathspec: copy and free owned memory
From: Brandon Williams @ 2016-12-08 18:59 UTC (permalink / raw)
To: git; +Cc: Brandon Williams, sbeller, pclouds, gitster
In-Reply-To: <1481223550-65277-1-git-send-email-bmwill@google.com>
The 'original' string entry in a pathspec_item is only duplicated some
of the time, instead always make a copy of the original and take
ownership of the memory.
Since both 'match' and 'original' string entries in a pathspec_item are
owned by the pathspec struct, they need to be freed when clearing the
pathspec struct (in 'clear_pathspec()') and duplicated when copying the
pathspec struct (in 'copy_pathspec()').
Also change the type of 'match' and 'original' to 'char *' in order to
more explicitly show the ownership of the memory.
