reachable: per-object progress

The current progress code really just counts commits.
This patch makes it count all objects, giving us a "total"
count close to what a repack would show. This is nice when
using "git gc", which will usually have just repacked the

13 years agoparse-options: deprecate OPT_BOOLEAN
Junio C Hamano [Tue, 27 Sep 2011 23:56:49 +0000 (16:56 -0700)]
parse-options: deprecate OPT_BOOLEAN

It is natural to expect that an option defined with OPT_BOOLEAN() could be
used in this way:

int option = -1; /* unspecified */

struct option options[] = {
OPT_BOOLEAN(0, "option", &option, "set option"),
                OPT_END()
};
parse_options(ac, av, prefix, options, usage, 0);

        if (option < 0)
         ... do the default thing ...
else if (!option)
... --no-option was given ...
else
... --option was given ...

to easily tell three cases apart:

 - There is no mention of the `--option` on the command line;
 - The variable is positively set with `--option`; or
 - The variable is explicitly negated with `--no-option`.

Unfortunately, this is not the case. OPT_BOOLEAN() increments the variable
every time `--option` is given, and resets it to zero when `--no-option`
is given.

As a first step to remedy this, introduce a true boolean OPT_BOOL(), and
rename OPT_BOOLEAN() to OPT_COUNTUP(). To help transitioning, OPT_BOOLEAN
and OPTION_BOOLEAN are defined as deprecated synonyms to OPT_COUNTUP and
OPTION_COUNTUP respectively.

This is what db7244b (parse-options new features., 2007-11-07) from four
years ago started by marking OPTION_BOOLEAN as "INCR would have been a
better name".

Some existing users do depend on the count-up semantics; for example,
users of OPT__VERBOSE() could use it to raise the verbosity level with
repeated use of `-v` on the command line, but they probably should be
rewritten to use OPT__VERBOSITY() instead these days.  I suspect that some
users of OPT__FORCE() may also use it to implement different level of
forcibleness but I didn't check.

On top of this patch, here are the remaining clean-up tasks that other
people can help:

 - Look at each hit in "git grep -e OPT_BOOLEAN"; trace all uses of the
   value that is set to the underlying variable, and if it can proven that
   the variable is only used as a boolean, replace it with OPT_BOOL(). If
   the caller does depend on the count-up semantics, replace it with
   OPT_COUNTUP() instead.

 - Same for OPTION_BOOLEAN; replace it with OPTION_SET_INT and arrange to
   set 1 to the variable for a true boolean, and otherwise replace it with
   OPTION_COUNTUP.

 - Look at each hit in "git grep -e OPT__VERBOSE -e OPT__QUIET" and see if
   they can be replaced with OPT__VERBOSITY().

I'll follow this message up with a separate patch as an example.

revision with multiple parents, all but (potentially) the first of
which have been committed to SVN in the same repository as the target

In this case, the merge info is the union of that given by each of the
parents, plus all changes introduced to the first parent by the other
parents.

In all other cases where a revision to be committed has multiple
parents, cause "git svn dcommit" to raise an error rather than
completing the commit and potentially losing history information in

invoking a remote helper to choose from.  In practice, that's less

started.  So preface the command list with an overview of each
capability, its purpose, and what commands it requires.

As a side effect, this makes it a little clearer that git doesn't
choose arbitrary commands to run, even if the remote helper advertises
all capabilities --- instead, there are well defined command sequences
for various tasks.

13 years agostrbuf_grow(): maintain nul-termination even for new buffer
Thomas Rast [Mon, 29 Aug 2011 21:16:12 +0000 (23:16 +0200)]
strbuf_grow(): maintain nul-termination even for new buffer

In the case where sb is initialized to the slopbuf (through
strbuf_init(sb,0) or STRBUF_INIT), strbuf_grow() loses the terminating
nul: it grows the buffer, but gives ALLOC_GROW a NULL source to avoid
it being freed.  So ALLOC_GROW does not copy anything to the new
memory area.

This subtly broke the call to strbuf_getline in read_next_command()
[fast-import.c:1855], which goes

    strbuf_detach(&command_buf, NULL);  # command_buf is now = STRBUF_INIT
    stdin_eof = strbuf_getline(&command_buf, stdin, '\n');
    if (stdin_eof)
            return EOF;

In strbuf_getwholeline, this did

    strbuf_grow(sb, 0);  # loses nul-termination
    if (feof(fp))
            return EOF;
    strbuf_reset(sb);    # this would have nul-terminated!

Valgrind found this because fast-import subsequently uses prefixcmp()
on command_buf.buf, which after the EOF exit contains only
uninitialized memory.

Arguably strbuf_getwholeline is also broken, in that it touches the
buffer before deciding whether to do any work.  However, it seems more
futureproof to not let the strbuf API lose the nul-termination by its
own fault.

So make sure that strbuf_grow() puts in a nul even if it has nowhere
to copy it from.  This makes strbuf_grow(sb, 0) a semantic no-op as
far as readers of the buffer are concerned.

Also remove the nul-termination added by strbuf_init, which is made
redudant.

t4014: "no-add-headers" is actually called "no-add-header"

Since c426003 (format-patch: add --no-cc, --no-to, and
--no-add-headers, 2010-03-07) the tests have checked for an option
called --no-add-headers introduced by letting the user negate
--add-header.

However, the parseopt machinery does not automatically pluralize
anything, so it is in fact called --no-add-header.

Since the option never worked, is not documented anywhere, and
implementing an actual --no-add-headers would lead to silly code
complications, we just adapt the test to the code.

t4014: check for empty files from git format-patch --stdout

patch (or cover letter) email.  Then insert calls to it in all tests
that do have positive checks for content.

fixed in a moment.
