SUMMARY OF MY PROJECT:
Git submodule subcommands are currently implemented by using shell script
'git-submodule.sh'. There are several reasons why we'll prefer not to
use the shell script. My project intends to convert the subcommands into
C code, thus making them builtins. This will increase Git's portability
and hence the efficiency of working with the git-submodule commands.
Link to the complete proposal: [1]
Mentors:
Stefan Beller <sbeller@google.com>
Christian Couder <christian.couder@gmail.com>
UPDATES:
Following are the updates about my ongoing project:
1. sync and status: The patches were discussed with the mentors
and after that, are being posted with this patch.
2. deinit: The patch is debugged, and is ready to be
discussed. Not much discussion occurred over this patch
and hence the patch is same as its previous version.
It is also attached with this update.
3. summary: The porting of this submodule subcommand is
almost completed. Things like improving the function
names, checking for memory leakage, etc are still
left to be taken care of. I'm updating the patch's status
by sending the patch to the mentors off-list, so that
an appropriate version is posted here on the list.
Hence, it wasn't attached to the update.
4. foreach: Not much progress was done with this patch
in particular as most of the time was used for completing
the porting of submodule subcommand 'summary'.
Hence its status remains same as mentioned in the
previous update, which is reposted below:
'As stated in the previous update, the subcommand was
ported without resolving the bug, and simply translating the
present code, and adding a NEEDSWORK tag to the comment for
mentioning the reported bug as well.
But as communicating between child_process is still an issue
and so there was no simple was to current carry out the
porting. And hence, a hack was used instead. But after
discussing it, instead using the repository-object patch
series will help to resolve these issues in this situation.'
PLAN FOR WEEK-7 (27 June 2017 to 3 July 2017):
1. foreach: Since the required changes weren't made in the last
week in regards with this patch, in the next week I aim for
fulfilling them first. I'll like to again mention it here:
As it was decided that unblock the conversion of
this submodule subcommand, the original cmd_foreach was
ported without including the BUG-FIX patch here.
Hence, for this week I will try to utilize the
'repository-object' series by Brandon Williams.
Additionally, I'll like to mention that this update
still, doesn't depend on the 'repository-object' series,
which I'll be trying to change in the next update.
2. summary: As mentioned earlier, since there is still a little
work with its porting left, I'll try to finish it and debug
the ported code as well.
3. deinit: As there is still scope of improvision and discussion
I'll also be focussing on improving this patch.

Introduce function for_each_submodule_list for using it
in the later patches, related to porting submodule
subcommands from shell to C.
This new function is also used in ported submodule subcommand
init.

This aims to make git-submodule foreach a builtin. This is the very
first step taken in this direction. Hence, 'foreach' is ported to
submodule--helper, and submodule--helper is called from git-submodule.sh.
The code is split up to have one function to obtain all the list of
submodules. This function acts as the front-end of git-submodule foreach
subcommand. It calls the function for_each_submodule_list, which basically
loops through the list and calls function fn, which in this case is
runcommand_in_submodule. This third function is a calling function that
takes care of running the command in that submodule, and recursively
perform the same when --recursive is flagged.
The first function module_foreach first parses the options present in
argv, and then with the help of module_list_compute, generates the list of
submodules present in the current working tree.
The second function for_each_submodule_list traverses through the
list, and calls function fn (which in case of submodule subcommand
foreach is runcommand_in_submodule) is called for each entry.
The third function runcommand_in_submodule, generates a submodule struct sub
for $name, value and then later prepends name=sub->name; and other
value assignment to the env argv_array structure of a child_process.
Also the <command> of submodule-foreach is push to args argv_array
structure and finally, using run_command the commands are executed
using a shell.
The third function also takes care of the recursive flag, by creating
a separate child_process structure and prepending "--super-prefix displaypath",
to the args argv_array structure. Other required arguments and the
input <command> of submodule-foreach is also appended to this argv_array.
Function get_initial_wt_prefix_up_path is introduced to take care of
generating the value for path variable(as it was in the shell script)

This patch suggestes the current status of the foreach patch.
Work is still needed on this patch for eleminating the hack
used in this patch for generating path variable.

Since later on we want to port submodule subcommand status, and since
set_name_rev is part of cmd_status, hence this function is ported. It
has been ported to function print_name_rev in C, which calls get_name_rev
to get the revname, and after formatting it, print_name_rev prints it.
And hence in this way, the command `git submodule--helper print-name-rev
"sm_path" "sha1"` sets value of revname in git-submodule.sh
The function get_name_rev returns the stdout of the git describe
commands. Since there are four different git-describe commands used for
generating the name rev, four child_process are introduced, each successive
child process running only when previous has no stdout. The order of these
four git-describe commands is maintained the same as it was in the function
set_name_rev() in shell script.

The mechanism used for porting submodule subcommand 'status'
is similar to that used for subcommand 'foreach'.
The function cmd_status from git-submodule is ported to three
functions in the builtin submodule--helper namely: module_status,
for_each_submodule_list and status_submodule.
print_status is also introduced for handling the output of
the subcommand and also to reduce the code size.

The mechanism used for porting the submodule subcommand 'sync' is
similar to that of 'foreach', where we split the function cmd_sync
from shell into three functions in C, module_sync,
for_each_submodule_list and sync_submodule.
print_default_remote is introduced as a submodule--helper
subcommand for getting the default remote as stdout.

The same mechanism is used even for porting this submodule
subcommand, as used in the ported subcommands till now.
The function cmd_deinit in split up after porting into three
functions: module_deinit, for_each_submodule_list and
deinit_submodule.

As this comment spans over more than one line, it should be like:
/*

*/
Also please explain WHY a shell is needed, we can see from the code
that we will use a shell.
So it should be something like:

Nit: "l" is quite similar to "i" in many fonts, so maybe use "len"
instead of "l", but see below.

Nit: a regular "for" loop like the following might be easier to review:
for (i = count_slashes(path); i; i--)
strbuf_addstr(&sb, "../");

As "l" is used only here, maybe we could get rid of this variable
altogether with something like:
if (!is_dir_sep(path[strlen(path) - 1]))

In the previous patch "!sub" is used before "!sub->url", so we might
want to check "!sub" here too.

It looks like cmd_rm() is not used anymore below, so this comment
could go and the sm_path variable might not be needed any more.

Are you sure about the 0700 mode?
Shouldn't this depend on the shared repository settings?

The patch text looks sensible. It would be easier for "git log"
readers to understand, if the change is explained like so:
Introduce function for_each_submodule_list() and
replace a loop in module_init() with a call to it.
The new function will also be used in other parts of the
system in later patches.
That way, readers do not have to judge the merit of this change
based on a vague promise "it will help world better with future
patches", but can instead judge on its immediate benefit that it
refactors a useful bit out of an existing code.

The reason not to base on 'master' is...?
The thing is that a topic built on 'next' cannot be merged down to
'master' until _all_ other topics in 'next' graduate to 'master',
which may never happen. If you are depending on one or more topics,
please make sure to name them. Then we can
(1) create a branch from the tip of 'master';
(2) merge these topics you depend on into that branch; and then
(3) apply these patches.
The topic still needs to wait until these other topis graduate, but
at least you would not be blocked by unrelated topics that way.
You _might_ be building on 'next' because you want to make sure that
your topic works not just with master but also want to make sure
that there won't be any unexpected breakage when used with topics in
'next', even though your topic does not depend on anything in 'next'
in particular. It is a good development discipline to pay attention
to other topics in flight and I applaud you for it if that is why
you based it on 'next'. But the right way to do it would be to
build your topic on 'master', and then in addition to testing the
topic by itself, also make a trial merge of your topic into 'next'
and test the result as well.
Thanks.

The reason it wasn't based on 'master' was that it depended on the commit:
dir: create function count_slashes(),
which was merged to 'next' a few days back.

Introduce function get_submodule_displaypath() to replace the code
occurring in submodule_init() for generating displaypath of the
submodule with a call to it.
This new function will also be used in other parts of the system
in later patches.

The patch series is updated, and is based on 'master' branch.
This patch series contains updates patches about
Introduction of the function: get_submodule_displaypath()
(This patch wasn't posted in the last update by mistake)
Introduction of the function: for_each_submodule()
Port shell function set_name_rev() to C
Port submodule subcommand 'status' from shell to C
Port submodule subcommand 'sync' from shell to C
Complete build report of this patch-series is available at:
https://travis-ci.org/pratham-pc/git/builds
Branch: patch-series-1
Build #114
Also, the above series was also build by basing it on the 'next'
branch for the purpose of testing the code.
Since the function is_submodule_initialized changed to
is_submodule_active, this change was required to be added in the
above patches while basing it on next.
After doing the required changes,
Complete build report of the above is available at:
https://travis-ci.org/pratham-pc/git/builds
Branch: patch-series-1-next
Build #116
I have held back the following patch since some work is still
required to be done:
Port submodule subcommand 'foreach' from shell to C
Port submodule subcommand 'deinit' from shell to C
Port submodule subcommand 'summary' from shell to C
I hope to complete this and post these patches later with the
weekly updates.

Function set_name_rev() is ported from git-submodule to the
submodule--helper builtin. The function get_name_rev() generates the
value of the revision name as required, and the function
print_name_rev() handles the formating and printing of the obtained
revision name.

This aims to make git-submodule 'status' a built-in. Hence, the function
cmd_status() is ported from shell to C. This is done by introducing
three functions: module_status(), submodule_status() and print_status().
The function module_status() acts as the front-end of the subcommand.
It parses subcommand's options and then calls the function
module_list_compute() for computing the list of submodules. Then
this functions calls for_each_submodule_list() looping through the
list obtained.
Then for_each_submodule_list() calls submodule_status() for each of the
submodule in its list. The function submodule_status() is responsible
for generating the status each submodule it is called for, and
then calls print_status().
Finally, the function print_status() handles the printing of submodule's
status.

Port the submodule subcommand 'sync' from shell to C using the same
mechanism as that used for porting submodule subcommand 'status'.
Hence, here the function cmd_sync() is ported from shell to C.
This is done by introducing three functions: module_sync(),
sync_submodule() and print_default_remote().
The function print_default_remote() is introduced for getting
the default remote as stdout.

Hmph.
The only difference between the steps being what subcommand is run,
a better implementation might be to do
static const char *describe_bare[] = {
NULL
};
...
static const char **describe_argv[] = {
describe_bare, describe_tags, describe_contains,
describe_all_always, NULL
};
const char ***d;
for (d = describe_argv; *d; d++) {
argv_array_pushl(&cp.args, "describe");
argv_array_pushv(&cp.args, *d);
... do the thing ...
}
but unfortunately C is a bit klunky to do so; we cannot easily make
the contents of describe_argv[] as anonymous arrays. An otherwise
useless enum stil bothers me, but I do not think of anything better
offhand.

Dedent the body of switch() by one level, i.e.
switch (var) {
case val1:
do_this();
break;
case val2:
do_that();
...
}
Otherwise looking good.

Essentially we'd only want to run ce_match_stat() on list_item and
the current on-filesystem submodule. We not just know which path we
are interested in, but we already have the cache entry for it, so it
feels quite wasteful to go over the_index.cache[] once again to find
the cache entry that matches list_item->name. Yes, that is how the
scripted Porcelain did it, but it feels way overkill now we have
ready access to the lower level machinery.
Having said all that, I think it is a good idea to stick to a
faithful conversion in this series. I just think a NEEDSWORK
comment may be a good idea to indicate future optimization
opportunities.
A similar optimization is already happening in this patch, actually.
Instead of doing a stat of "$sm_path/.git" and checking test -d/-f,
the code just calls is_submodule_initialized(). Which is good ;-)

Likewise. This is merely resolving a ref inside a submodule;
calling something like head_ref_submodule() may be sufficient
as an optimization and at least deserves to be mentioned in a
NEEDSWORK comment.

Have a blank line between the decls and the first statement
(i.e. before "free(remote)"). The blank line after "free(remote)"
may or may not be there.

OK. Perhaps in a distant future when the repository object
abstraction is ready, we can do this within the main process, but
for now, due to the presence of cp.dir, this is the best we can do.

Likewise.
Looks like a fairly faithful conversion to me.

Introduce function get_submodule_displaypath() to replace the code
occurring in submodule_init() for generating displaypath of the
submodule with a call to it.
This new function will also be used in other parts of the system
in later patches.

Function set_name_rev() is ported from git-submodule to the
submodule--helper builtin. The function get_name_rev() generates the
value of the revision name as required, and the function
print_name_rev() handles the formating and printing of the obtained
revision name.

This aims to make git-submodule 'status' a built-in. Hence, the function
cmd_status() is ported from shell to C. This is done by introducing
three functions: module_status(), submodule_status() and print_status().
The function module_status() acts as the front-end of the subcommand.
It parses subcommand's options and then calls the function
module_list_compute() for computing the list of submodules. Then
this functions calls for_each_submodule_list() looping through the
list obtained.
Then for_each_submodule_list() calls submodule_status() for each of the
submodule in its list. The function submodule_status() is responsible
for generating the status each submodule it is called for, and
then calls print_status().
Finally, the function print_status() handles the printing of submodule's
status.

In this new version of patch:
Instead of using cmd_diff_files(), the process is optimized
by using ce_match_stat().
Also, the child_process running the command 'rev-parse --verify HEAD'
is removed for optimization reasons, and instead head_ref_submodule()
is used with callback function handle_submodule_head_ref().
The series differs from the complete weekly-update series as these patches
have been reviewed with mentors as well as on mailing list more no. of
times then the rest patches from the complete series, and hence
IMO, are ready for getting included. If not so, I would like to have
suggestions for improvising it.
The patches pass the complete test suite.

Port the submodule subcommand 'sync' from shell to C using the same
mechanism as that used for porting submodule subcommand 'status'.
Hence, here the function cmd_sync() is ported from shell to C.
This is done by introducing three functions: module_sync(),
sync_submodule() and print_default_remote().
The function print_default_remote() is introduced for getting
the default remote as stdout.

Apart from this I have reviewed the patch and found it a faithful
conversion.
I am not an expert in the diff area and wonder how
the cmd_diff_files functionality is achieved with just a stat call
and then comparing it to ce_match_stat. 'Using "dirty" ignores
all changes to the work tree of submodules, only changes to the
commits stored in the superproject are shown.' So I'd have
expected ce->oid to be compared (is there an index entry differing,
i.e. more than one stage?)

Cool.
