e36091aa1d factor out strbuf_expand_bad_format()
Extract a function for reporting placeholders that are not enclosed in a
parenthesis or are unknown.  This reduces the number of strings to
translate and improves consistency across commands.  Call it at the end
of the if/else chain, after exhausting all accepted possibilities.

2ec225d397 find multi-byte comment chars in unterminated buffers
As with the previous patch, we need to swap out single-byte matching for
something like starts_with() to match all bytes of a multi-byte comment
character. But for cases where the buffer is not NUL-terminated (and we
instead have an explicit size or end pointer), it's not safe to use
starts_with(), as it might walk off the end of the buffer.

Let's introduce a new starts_with_mem() that does the same thing but
also accepts the length of the "haystack" str and makes sure not to walk
past it.

Note that in most cases the existing code did not need a length check at
all, since it was written in a way that knew we had at least one byte
available (and that was all we checked). So I had to read each one to
find the appropriate bounds. The one exception is sequencer.c's
add_commented_lines(), where we can actually get rid of the length
check. Just like starts_with(), our starts_with_mem() handles an empty
haystack variable by not matching (assuming a non-empty prefix).

A few notes on the implementation of starts_with_mem():

  - it would be equally correct to take an "end" pointer (and indeed,
    many of the callers have this and have to subtract to come up with
    the length). I think taking a ptr/size combo is a more usual
    interface for our codebase, though, and has the added benefit that
    the function signature makes it harder to mix up the three
    parameters.

  - we could obviously build starts_with() on top of this by passing
    strlen(str) as the length. But it's possible that starts_with() is a
    relatively hot code path, and it should not pay that penalty (it can
    generally return an answer proportional to the size of the prefix,
    not the whole string).

  - it naively feels like xstrncmpz() should be able to do the same
    thing, but that's not quite true. If you pass the length of the
    haystack buffer, then strncmp() finds that a shorter prefix string
    is "less than" than the haystack, even if the haystack starts with
    the prefix. If you pass the length of the prefix, then you risk
    reading past the end of the haystack if it is shorter than the
    prefix. So I think we really do need a new function.

a1bb146aaf strbuf: accept a comment string for strbuf_add_commented_lines()
As part of our transition to multi-byte comment characters, let's take a
NUL-terminated string pointer for strbuf_add_commented_lines() rather
than a single character.

All of the callers have to be adjusted; most can just pass
comment_line_str rather than comment_line_char.

And now our "cheat" in strbuf_commented_addf() can go away, as we can
take the full string from it.

the two are equivalent, and we'll address this TODO in the next patch).

2982b65690 strbuf: accept a comment string for strbuf_stripspace()
As part of our transition to multi-byte comment characters, let's take a
NUL-terminated string pointer for strbuf_stripspace(), rather than a
single character. We can continue to support its feature of ignoring
comments by accepting a NULL pointer (as opposed to the current behavior
of a NUL byte).

All of the callers have to be adjusted, but they can all just pass
comment_line_str (or NULL).

Inside the function we detect comments by comparing the first byte of a
line to the comment character. We'll adjust that to use starts_with(),
which will match multiple bytes (though for now, of course, we still
only allow a single byte, so it's academic).

2786d058b6 strbuf: avoid shadowing global comment_line_char name
Several comment-related strbuf functions take a comment_line_char
parameter. There's also a global comment_line_char variable, which is
closely related (most callers pass it in as this parameter). Let's avoid
shadowing the global name. This makes it more obvious that we're not
using the global value, and it will be especially helpful as we refactor
the global in future patches (in particular, any macro trickery wouldn't
work because the preprocessor doesn't respect scope).

We'll use "comment_prefix". That should be descriptive enough, and as a
bonus is more neutral with respect to the "char" type (since we'll
eventually swap it out for a string).

to stop building correctly; fix it by having it include

787cb8a48a strbuf: remove global variable
As a library that only interacts with other primitives, strbuf should
not utilize the comment_line_char global variable within its
functions. Therefore, add an additional parameter for functions that use
comment_line_char and refactor callers to pass it in instead.

comment_line_char is a non-NUL character to determine whether to skip
comments or not.

af35e56b0f strbuf: provide CRLF-aware helper to read until a specified delimiter
Many of our commands support reading input that is separated either via
newlines or via NUL characters. Furthermore, in order to be a better
cross platform citizen, these commands typically know to strip the CRLF
sequence so that we also support reading newline-separated inputs on
e.g. the Windows platform. This results in the following kind of awkward
pattern:

```
struct strbuf input = STRBUF_INIT;

while (1) {
	int ret;

	if (nul_terminated)
		ret = strbuf_getline_nul(&input, stdin);
	else
		ret = strbuf_getline(&input, stdin);
	if (ret)
		break;

	...
}
```

Introduce a new CRLF-aware helper function that can read up to a user
specified delimiter. If the delimiter is `\n` the function knows to also
strip CRLF, otherwise it will only strip the specified delimiter. This
results in the following, much more readable code pattern:

```
struct strbuf input = STRBUF_INIT;

while (strbuf_getdelim_strip_crlf(&input, stdin, delim) != EOF) {
	...
}
```

The new function will be used in a subsequent commit.

9ea5796495 strbuf: introduce strbuf_strip_file_from_path()
The strbuf_parent_directory() method was added as a static method in

there is a need for a similar method in the bundle URI feature.

Re-add the method, this time in strbuf.c, but with a new name:
strbuf_strip_file_from_path(). The method requirements are slightly
modified to allow a trailing slash, in which case nothing is done, which
makes the name change valuable.

b44d0118ac credential: fix matching URLs with multiple levels in path
46fd7b3900 ("credential: allow wildcard patterns when matching config",
2020-02-20) introduced support for matching credential helpers using
urlmatch.  In doing so, it introduced code to percent-encode the paths
we get from the credential helper so that they could be effectively
matched by the urlmatch code.

Unfortunately, that code had a bug: it percent-encoded the slashes in
the path, resulting in any URL path that contained multiple levels
(i.e., a directory component) not matching.

We are currently the only caller of the percent-encoding code and could
simply change it not to encode slashes.  However, we still want to
encode slashes in the username component, so we need to have both
behaviors available.

So instead, let's add a flag to control encoding slashes, which is the
behavior we want here, and use it when calling the code in this case.

Add a test for credential helper URLs using multiple slashes in the
path, which our test suite previously lacked, as well as one ensuring
that we handle usernames with slashes gracefully.  Since we're testing
other percent-encoding handling, let's add one for non-ASCII UTF-8
characters as well.

238b439d69 bugreport: add tool to generate debugging info
Teach Git how to prompt the user for a good bug report: reproduction
steps, expected behavior, and actual behavior. Later, Git can learn how
to collect some diagnostic information from the repository.

If users can send us a well-written bug report which contains diagnostic
information we would otherwise need to ask the user for, we can reduce
the number of question-and-answer round trips between the reporter and
the Git contributor.

Users may also wish to send a report like this to their local "Git
expert" if they have put their repository into a state they are confused
by.

bd021f3910 strbuf: provide function to append whole lines
While the strbuf interface already provides functions to read a line
into it that completely replaces its current contents, we do not have an
interface that allows for appending lines without discarding current
contents.

Add a new function `strbuf_appendwholeline` that reads a line including
its terminating character into a strbuf non-destructively. This is a
preparatory step for git-update-ref(1) reading standard input line-wise
instead of as a block.

46fd7b3900 credential: allow wildcard patterns when matching config
In some cases, a user will want to use a specific credential helper for
a wildcard pattern, such as https://*.corp.example.com.  We have code
that handles this already with the urlmatch code, so let's use that
instead of our custom code.

Since the urlmatch code is a superset of our current matching in terms
of capabilities, there shouldn't be any cases of things that matched
previously that don't match now.  However, in addition to wildcard
matching, we now use partial path matching, which can cause slightly
different behavior in the case that a helper applies to the prefix
(considering path components) of the remote URL.  While different, this
is probably the behavior people were wanting anyway.

Since we're using the urlmatch code, we need to encode the components
we've gotten into a URL to match, so add a function to percent-encode
data and format the URL with it.  We now also no longer need to the
custom code to match URLs, so let's remove it.

Additionally, the urlmatch code always looks for the best match, whereas
we want all matches for credential helpers to preserve existing
behavior.  Let's add an optional field, select_fn, that lets us control
which items we want (in this case, all of them) and default it to the
best-match code that already exists for other users.

a91cc7fad0 strbuf: add and use strbuf_insertstr()
Add a function for inserting a C string into a strbuf.  Use it
throughout the source to get rid of magic string length constants and
explicit strlen() calls.

Like strbuf_addstr(), implement it as an inline function to avoid the
implicit strlen() calls to cause runtime overhead.

b38dd9e715 strbuf: add a helper function to call the editor "on an strbuf"
This helper supports the scenario where Git has a populated `strbuf` and
wants to let the user edit it interactively.

In `git add -p`, we will use this to allow interactive hunk editing: the
diff hunks are already in memory, but we need to write them out to a
file so that an editor can be launched, then read everything back once
the user is done editing.

8f354a1fae l10n: localizable upload progress messages
Currenly the data rate in throughput_string(...) method is
output by simple strbuf_humanise_bytes(...) call and '/s' append.
But for proper translation of such string the translator needs
full context.

Add strbuf_humanise_rate(...) method to properly print out
localizable version of data rate ('3.5 MiB/s' etc) with full context.

Strings with the units in strbuf_humanise_bytes(...) are marked
for translation.
