when a user pushes multiple branches such as:
Before using batched updates, the references would be applied
sequentially and hence no conflicts would arise. With batched updates,
while the first update applies, the second fails due to D/F conflict. A
similar issue was present in 'git-fetch(1)' and was fixed by separating
out reference pruning into a separate transaction in the commit 'fetch:
use batched reference updates'. Apply a similar mechanism for
'git-receive-pack(1)' and separate out reference deletions into its own
batch.
This means 'git-receive-pack(1)' will now use up to two transactions,
whereas before using batched updates it would use _at least_ two
transactions. So using batched updates is still the better option.

test-lib: teach test_seq the -f option
The "seq" tool has a "-f" option to produce printf-style formatted
lines. Let's teach our test_seq helper the same trick. This lets us get
rid of some shell loops in test snippets (which are particularly verbose
in our test suite because we have to "|| return 1" to keep the &&-chain
going).
This converts a few call-sites I found by grepping around the test
suite. A few notes on these:
- In "seq", the format specifier is a "%g" float. Since test_seq only
supports integers, I've kept the more natural "%d" (which is what
these call sites were using already).
- Like "seq", test_seq automatically adds a newline to the specified
format. This is what all callers are doing already except for t0021,
but there we do not care about the exact format. We are just trying
to printf a large number of bytes to a file. It's not worth
complicating other callers or adding an option to avoid the newline
in that caller.
- Most conversions are just replacing a shell loop (which does get rid
of an extra fork, since $() requires a subshell). In t0612 we can
replace an awk invocation, which I think makes the end result more
readable, as there's less quoting.
- In t7422 we can replace one loop, but sadly we have to leave the
loop directly above it. This is because that earlier loop wants to
include the seq value twice in the output, which test_seq does not
support (nor does regular seq). If you run:
test_seq -f "foo-%d %d" 10
the second "%d" will always be the empty string. You might naively
think that test_seq could add some extra arguments, like:
# 3 ought to be enough for anyone...
printf "$fmt\n" "$i "$i" $i"
but that just triggers printf to format multiple lines, one per
extra set of arguments.
So we'd have to actually parse the format string, figure out how
many "%" placeholders are there, and then feed it that many
instances of the sequence number. The complexity isn't worth it.

submodule: look up remotes by URL first
The get_default_remote_submodule() function performs a lookup to find
the appropriate remote to use within a submodule. The function first
checks to see if it can find the remote for the current branch. If this
fails, it then checks to see if there is exactly one remote. It will use
this, before finally falling back to "origin" as the default.
If a user happens to rename their default remote from origin, either
manually or by setting something like clone.defaultRemoteName, this
fallback will not work.
In such cases, the submodule logic will try to use a non-existent
remote. This usually manifests as a failure to trigger the submodule
update.
The parent project already knows and stores the submodule URL in either
.gitmodules or its .git/config.
Add a new repo_remote_from_url() helper which will iterate over all the
remotes in a repository and return the first remote which has a matching
URL.
Refactor get_default_remote_submodule to find the submodule and get its
URL. If a valid URL exists, first try to obtain a remote using the new
repo_remote_from_url(). Fall back to the repo_default_remote()
otherwise.
The fallback logic is kept in case for some reason the user has manually
changed the URL within the submodule. Additionally, we still try to use
a remote rather than directly passing the URL in the
fetch_in_submodule() logic. This ensures that an update will properly
update the remote refs within the submodule as expected, rather than
just fetching into FETCH_HEAD.

submodule--helper: improve logic for fallback remote name
The repo_get_default_remote() function in submodule--helper currently
tries to figure out the proper remote name to use for a submodule based
on a few factors.
First, it tries to find the remote for the currently checked out branch.
This works if the submodule is configured to checkout to a branch
instead of a detached HEAD state.
In the detached HEAD state, the code calls back to using "origin", on
the assumption that this is the default remote name. Some users may
change this, such as by setting clone.defaultRemoteName, or by changing
the remote name manually within the submodule repository.
As a first step to improving this situation, refactor to reuse the logic
from remotes_remote_for_branch(). This function uses the remote from the
branch if it has one. If it doesn't then it checks to see if there is
exactly one remote. It uses this remote first before attempting to fall
back to "origin".
To allow using this helper function, introduce a repo_default_remote()
helper to remote.c which takes a repository structure. This helper will
load the remote configuration and get the "HEAD" branch. Then it will
call remotes_remote_for_branch to find the default remote.
Replace calls of repo_get_default_remote() with the calls to this new
function. To maintain consistency with the existing callers, continue
copying the returned string with xstrdup.
This isn't a perfect solution for users who change remote names, but it
should help in cases where the remote name is changed but users haven't
added any additional remotes.

remote: remove branch->merge_name and fix branch_release()
The branch structure has both branch->merge_name and branch->merge for
tracking the merge information. The former is allocated by add_merge()
and stores the names read from the configuration file. The latter is
allocated by set_merge() which is called by branch_get() when an
external caller requests a branch.
This leads to the confusing situation where branch->merge_nr tracks both
the size of branch->merge (once its allocated) and branch->merge_name.
The branch_release() function incorrectly assumes that branch->merge is
always set when branch->merge_nr is non-zero, and can potentially crash
if read_config() is called without branch_get() being called on every
branch.
In addition, branch_release() fails to free some of the memory
associated with the structure including:
* Failure to free the refspec_item containers in branch->merge[i]
* Failure to free the strings in branch->merge_name[i]
* Failure to free the branch->merge_name parent array.
The set_merge() function sets branch->merge_nr to 0 when there is no
valid remote_name, to avoid external callers seeing a non-zero merge_nr
but a NULL merge array. This results in failure to release most of the
merge data as well.
These issues could be fixed directly, and indeed I initially proposed
such a change at [1] in the past. While this works, there was some
confusion during review because of the inconsistencies.
Instead, its time to clean up the situation properly. Remove
branch->merge_name entirely. Instead, allocate branch->merge earlier
within add_merge() instead of within set_merge(). Instead of having
set_merge() copy from merge_name[i] to merge[i]->src, just have
add_merge() directly initialize merge[i]->src.
Modify the add_merge() to call xstrdup() itself, instead of having
the caller of add_merge() do so. This makes it more obvious which code
owns the memory.
Update all callers which use branch->merge_name[i] to use
branch->merge[i]->src instead.
Add a merge_clear() function which properly releases all of the
merge-related memory, and which sets branch->merge_nr to zero. Use this
both in branch_release() and in set_merge(), fixing the leak when
set_merge() finds no valid remote_name.
Add a set_merge variable to the branch structure, which indicates
whether set_merge() has been called. This replaces the previous use of a
NULL check against the branch->merge array.
With these changes, the merge array is always allocated when merge_nr is
non-zero.
This use of refspec_item to store the names should be safe. External
callers should be using branch_get() to obtain a pointer to the branch,
which will call set_merge(), and the callers internal to remote.c
already handle the partially initialized refpsec_item structure safely.
This end result is cleaner, and avoids duplicating the merge names
twice.

only the host name. For example:
Password for 'imaps://gargaditya08%40live.com@outlook.office365.com':
Now, it will display the port along with the host name:
Password for 'imaps://gargaditya08%40live.com@outlook.office365.com:993':
This has been done to make credential helpers more specific for ports.
Also, this behaviour will also mimic git send-email, which displays
the port along with the host name when requesting for a password.

imap-send: add ability to list the available folders
Various IMAP servers have different ways to name common folders.
For example, the folder where all deleted messages are stored is often
named "[Gmail]/Trash" on Gmail servers, and "Deleted" on Outlook.
Similarly, the Drafts folder is simply named "Drafts" on Outlook, but
on Gmail it is named "[Gmail]/Drafts".
This commit adds a `--list` command to the `imap-send` tool that lists
the available folders on the IMAP server, allowing users to see
which folders are available and how they are named. A sample output
looks like this when run against a Gmail server:
Fetching the list of available folders...
* LIST (\HasNoChildren) "/" "INBOX"
* LIST (\HasChildren \Noselect) "/" "[Gmail]"
* LIST (\All \HasNoChildren) "/" "[Gmail]/All Mail"
* LIST (\Drafts \HasNoChildren) "/" "[Gmail]/Drafts"
* LIST (\HasNoChildren \Important) "/" "[Gmail]/Important"
* LIST (\HasNoChildren \Sent) "/" "[Gmail]/Sent Mail"
* LIST (\HasNoChildren \Junk) "/" "[Gmail]/Spam"
* LIST (\Flagged \HasNoChildren) "/" "[Gmail]/Starred"
* LIST (\HasNoChildren \Trash) "/" "[Gmail]/Trash"
For OpenSSL, this is achived by running the 'IMAP LIST' command and
parsing the response. This command is specified in RFC6154:
https://datatracker.ietf.org/doc/html/rfc6154#section-5.1
For libcurl, the example code published in the libcurl documentation
is used to implement this functionality:
https://curl.se/libcurl/c/imap-list.html

imap-send: add PLAIN authentication method to OpenSSL
The current implementation for PLAIN in imap-send works just fine
if using curl, but if attempted to use for OpenSSL, it is treated
as an invalid mechanism. The default implementation for OpenSSL is
IMAP LOGIN command rather than AUTH PLAIN. Since AUTH PLAIN is
still used today by many email providers in form of app passwords,
lets add an implementation that can use AUTH PLAIN if specified.

imap-send: add support for OAuth2.0 authentication
OAuth2.0 is a new way of authentication supported by various email providers
these days. OAUTHBEARER and XOAUTH2 are the two most common mechanisms used
for OAuth2.0. OAUTHBEARER is described in RFC5801[1] and RFC7628[2], whereas
XOAUTH2 is Google's proprietary mechanism (See [3]).

imap-send: gracefully fail if CRAM-MD5 authentication is requested without OpenSSL
Unlike PLAIN, XOAUTH2 and OAUTHBEARER, CRAM-MD5 authentication is not
supported by libcurl and requires OpenSSL. If the user tries to use
CRAM-MD5 authentication without OpenSSL, the previous behaviour was to
attempt to authenticate and fail with a die(error). Handle this in a
better way by first checking if OpenSSL is available and then attempting
to authenticate. If OpenSSL is not available, print an error message and
exit gracefully.

imap-send: fix bug causing cfg->folder being set to NULL
6d1f198f34 (imap-send: fix leaking memory in `imap_server_conf`, 2024-06-07)
resulted a change in static int git_imap_config which resulted in cfg->folder
being incorrectly set to NULL in case imap.user, imap.pass, imap.tunnel and
imap.authmethod were defined. Because of this, since Git 2.46.0,
git-imap-send is not usable at all. The bug seems to have been unnoticed for
a long time, likely due to better options like git-send-email.
