When a push specifies deletion of non-existent refs, the post post-receive and
post-update hooks receive them as input/arguments.
For instance, for the following push, where refs/heads/nonexistent is a ref
which does not exist on the remote side:
git push origin :refs/heads/nonexistent
the post-receive hook receives from standard input:
<null-sha1> SP <null-sha1> SP refs/heads/nonexistent
and the post-update hook receives as arguments:
refs/heads/nonexistent
which does not make sense since it is a no-op.
Teach receive-pack not to pass non-existent refs to the post-receive and
post-update hooks. If the push only attempts to delete non-existent refs,
these hooks are not even called.
The update and pre-receive hooks are still notified about attempted
deletion of non-existent refs to give them a chance to inspect the
situation and act on it.

some tests]

Checking paths out of a tree is (currently) defined to do:
- Grab the paths from the named tree that match the given pathspec,
and add them to the index;
- Check out the contents from the index for paths that match the
pathspec to the working tree; and while at it
- If the given pathspec did not match anything, suspect a typo from the
command line and error out without updating the index nor the working
tree.
Suppose that the branch you are working on has dir/myfile, and the "other"
branch has dir/other but not dir/myfile. Further imagine that you have
either modified or removed dir/myfile in your working tree, but you have
not run "git add dir/myfile" or "git rm dir/myfile" to tell Git about your
local change. Running
$ git checkout other dir
would add dir/other to the index with the contents taken out of the
"other" branch, and check out the paths from the index that match the
pathspec "dir", namely, "dir/other" and "dir/myfile", overwriting your
local changes to "dir/myfile", even though "other" branch does not even
know about that file.
Fix it by updating the working tree only with the index entries that
was read from the "other" tree.

git send-email was not authenticating properly when communicating over
TLS with a server supporting only AUTH PLAIN and AUTH LOGIN. This is
e.g. the standard server setup under debian with exim4 and probably
everywhere where system accounts are used.
The problem (only?) exists when libauthen-sasl-cyrus-perl
(Authen::SASL::Cyrus) is installed. Importing Authen::SASL::Perl
makes Authen::SASL use the perl implementation which works
better.
The solution is based on this forum thread:
http://www.perlmonks.org/?node_id=904354.
This patch is tested by sending it. Without this fix, the interaction with
the server failed like this:

In the case of a wide breadth top-level tree (~2400 entries, all trees
in this case), we can see a noticeable cost in the profiler calling
strncmp() here. Most of the time we are at the base level of the
repository, so base is "" and baselen == 0, which means we will always
test true. Break out this one tiny case so we can short circuit the
strncmp() call.
Test cases are as follows. packages.git is the Arch Linux git-svn clone
of the packages repository which has the characteristics above.
Commands:
[1] packages.git, /usr/bin/time git log >/dev/null
[2] packages.git, /usr/bin/time git log -- autogen/trunk pacman/trunk wget/trunk >/dev/null
[3] linux.git, /usr/bin/time git log >/dev/null
[4] linux.git, /usr/bin/time git log -- drivers/ata drivers/uio tools >/dev/null
Results:
before after %faster
[1] 2.56 2.55 0.4%
[2] 51.82 48.66 6.5%
[3] 5.58 5.61 -0.5%
[4] 1.55 1.51 0.2%
The takeaway here is this doesn't matter in many operations, but it does
for a certain style of repository and operation where it nets a 6.5%
measured improvement. The other changes are likely not significant by
reasonable statistics methods.
Note: the measured improvement when originally submitted was ~11% (43 to
38 secs) for operation [2]. At the time, the repository had 117220
commits; it now has 137537 commits.

The list variable (which is OPT_BOOLEAN) is initialized to 0 and only
checked against 0 in the code, so it is safe to use OPT_BOOL().
The worktree_attributes variable (which is OPT_BOOLEAN) is initialized to
0 and later assigned to a field with the same name in struct archive_args,
which is a bitfield of width 1. It is safe and even more correct to use
OPT_BOOL() here; the new test in 5001 demonstrates why using OPT_COUNTUP
is wrong.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.

The fixLinks() function adds 'js=1' to each link that does not already
have 'js' query parameter specified. This is used to signal to gitweb
that the browser can actually do javascript when these links are used.
There are two problems with the existing code:
1. URIs with fragment and 'js' query parameter, like e.g.
...foo?js=0#l199
were not recognized as having 'js' query parameter already.
2. The 'js' query parameter, in the form of either '?js=1' or ';js=1'
was appended at the end of URI, even if it included a fragment
(had a hash part). This lead to the incorrect links like this
...foo#l199?js=1
instead of adding query parameter as last part of query, but
before the fragment part, i.e.
...foo?js=1#l199

get_ref_dir is called recursively for subdirectories, which means that
we were calling sort_ref_list for each directory of refs instead of
once for all the refs. This is a massive wast of processing, so now
just call sort_ref_list on the result of the top-level get_ref_dir, so
that the sort is only done once.
In the common case of only a few different directories of refs the
difference isn't very noticable, but it becomes very noticeable when
you have a large number of direcotries containing refs (e.g. as
created by Gerrit).

The negation example uses '*' to match everything. This used to work
before 9037026 (unpack-trees: fix sparse checkout's "unable to match
directories") because back then, the list of paths is used to match
sparse patterns, so with the patterns
*
!subdir/
subdir/ always matches any path that start with subdir/ and "*" has no
chance to get tested. The result is subdir is excluded.
After the said commit, a tree structure is dynamically created and
sparse pattern matching now follows closely how read_directory()
applies .gitignore. This solves one problem, but reveals another one.
With this new strategy, "!subdir/" rule will be only tested once when
"subdir" directory is examined. Entries inside subdir, when examined,
will match "*" and are (correctly) re-added again because any rules
without a slash will match at every directory level. In the end, "*"
can revert every negation rules.
In order to correctly exclude subdir, we must use
/*
!subdir
to limit "match all" rule at top level only.
"*" rule has no actual use in sparse checkout and can be confusing to
users. While we can automatically turn "*" to "/*", this violates
.gitignore definition. Instead, discourage "*" in favor of "/*" (in
the second example).

Files matching the pathspec are filtered so mergetool only acts on

other stages.

The description of .git/info/sparse-checkout and
skip-worktree is exactly the opposite of what is true, which is:
If a file matches a pattern in sparse-checkout, then (it is to be
checked out and therefore) skip-worktree is unset for that file;
otherwise, it is set (so that it is not checked out).
Currently, the opposite is documented, and (consistently) read-tree's
behavior with respect to bit flips is descibed incorrectly.
Fix it.
In hindsight, it would have been much better to have a "sparse-ignore"
or "sparse-skip" file so that an empty file would mean a full checkout,
and the file logic would be analogous to that of .gitignore, excludes
and skip-worktree.
