The confirmation tests in t9001 all save the value of
sendemail.confirm, do something to it, then restore it at
the end, in a way that breaks the &&-chain (they are not
wrong, because they save the $? value, but it fools
--chain-lint).
Instead, they can all use test_when_finished, and we can
even make the code simpler by factoring out the shared
lines.
Note that we can _almost_ use test_config here, except that:
1. We do not restore the config with test_unconfig, but by
setting it back to some prior value.
2. We are not always setting a config variable. Sometimes
the change to be undone is unsetting it entirely.
We could teach test_config to handle these cases, but it's
not worth the complexity for a single call-site.

We can get rid of a lot of hand-rolled error messages by
using test_must_fail and test_expect_code. The existing code
was careful to use "|| return 1" when breaking the
&&-chain, but it did fool --chain-lint; the new code is more
idiomatic.
We also add some uses of test_when_finished, which is less
cryptic and more robust than putting code at the end of a
test. In two cases we run "git bisect reset" from a
subshell, which is a problem for test_when_finished (it
would not run). However, in both of these cases, we are
performing the tests in one-off sub-repos, so we do not need
to clean up at all (and in fact it is nicer not to if the
user wants to inspect the trash directory after a failure).

This script misses a trivial &&-chain in one of its tests,
but it also has a weird reverse: it includes an &&-chain
outside of any test_expect block! This "cat" should never
fail, but if it did, we would not notice, as it would cause
us to skip the follow-on test entirely (which does not
appear intentional; there are many later tests which rely on
this cat).
Let's instead move the setup into its own test_expect_success
block, which is the standard practice nowadays.

One of these breakages is in setup, but one is more severe
and may miss a real test failure. These are pulled out from
the rest, though, because we also clean up a few other
anachronisms. The most interesting is the use of this
here-doc construct:
(cat >... <<EOF
...
EOF
) &&
It looks like an attempt to make the &&-chaining more
natural by letting it come at the end of the here-doc. But
the extra sub-shell is so non-idiomatic (plus the lack of
"<<-") that it ends up confusing.
Since these are just using a single line, we can accomplish
the same thing with a single printf (which also makes the
use of tab more obvious than the verbatim whitespace).

As with the earlier patch to fix "trivial" &&-chain
breakage, these missing "&&" operators are not a serious
problem (e.g., we do not expect "echo" to fail).
Ironically, however, inserting them shows that some of the
commands _do_ fail. Specifically, some of the tests start by
making sure we are at a commit with the string "content" in
the file "foo". However, running "git commit" may fail
because the previous test left us in that state already, and
there is nothing to commit.
We could remove these commands entirely, but they serve to
document the test's assumptions, as well as make it robust
when an earlier test has failed. We could use test_might_fail
to handle all cases, but that would miss an unrelated
failure to make the commit. Instead, we can just pass the
--allow-empty flag to git-commit, which means that it will
not complain if our setup is a noop.

If we are expecting a command to produce a particular exit
code, we can use test_expect_code. However, some cases are
more complicated, and want to accept one of a range of exit
codes. For these, we end up with something like:
cmd;
case "$?" in
...
That unfortunately breaks the &&-chain and fools
--chain-lint. Since these special cases are so few, we can
wrap them in a block, like this:
{ cmd; ret=$?; } &&
case "$ret" in
...
This accomplishes the same thing, and retains the &&-chain
(the exit status fed to the && is that of the assignment,
which should always be true). It's technically longer, but
it is probably a good thing for unusual code like this to
stand out.

Some tests run diff or grep to produce an output, and then
compare the output to an expected value. We know the exit
code we expect these processes to have (e.g., grep yields 0
if it produced output and 1 otherwise), so it would not make
the test wrong to look for it. But the difference between
their output and the expected output (e.g., shown by
test_cmp) is much more useful to somebody debugging the test
than the test just bailing out.
These tests break the &&-chain to skip the exit-code check
of the process. However, we can get the same effect by using
test_might_fail. Note that in some cases the test did use
"|| return 1", which meant the test was not wrong, but it
did fool --chain-lint.

t: fix &&-chaining issues around setup which might fail
Many tests have an initial setup step that might fail based
on whether earlier tests in the script have succeeded or
not. Using a trick like "|| true" breaks the &&-chain,
missing earlier failures (and fooling --chain-lint).
We can use test_might_fail in some cases, which is correct
and makes the intent more obvious. We can also use
test_unconfig for unsetting config (and which is more
robust, as well).
The case in t9500 is an oddball. It wants to run cmd1 _or_
cmd2, and does it like:
cmd1 || cmd2 &&
other_stuff
It's not wrong in this case, but it's a bad habit to get
into, because it breaks the &&-chain if used anywhere except
at the beginning of the test (and we use the correct
solution here, putting it inside a block for precedence).

t: use test_must_fail instead of hand-rolled blocks
These test scripts likely predate test_must_fail, and can be
made simpler by using it (in addition to making them pass
--chain-lint).
The case in t6036 loses some verbosity in the failure case,
but it is so tied to a specific failure mode that it is not
worth keeping around (and the outcome of the test is not
affected at all).
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
Many tests that predate the "verbose" helper function use a
pattern like:
test ... || {
echo ...
false
}
to give more verbose output. Using the helper, we can do
this with a single line, and avoid a || which interacts
badly with &&-chaining (besides fooling --chain-lint, we hit
the error block no matter which command in the chain failed,
so we may often show useless results).
In most cases, the messages printed by "verbose" are equally
good (in some cases better; t6006 accidentally redirects the
message to a file!). The exception is t7001, whose output
suffers slightly. However, it's still enough to show the
user which part failed, given that we will have just printed
the test script to stderr.
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
Some tests call test_cmp, and if it fails show the actual
output generated. This is mostly pointless, as test_cmp will
already show a diff between the expected and actual output.
It also fools --chain-lint by putting an "||" in the middle
of the chain, so we'd rather not use this construct.
Note that these cases actually show a pre-processed version
of the data, rather than exactly what test_cmp would show.
However, test_cmp's output is generally good for pointing
the user in the right direction, and they can then dig in
the trash directory themselves if they want to see more
details.

The test harness will notice if cmd3 fails, but a failure of
cmd1 or cmd2 will go unnoticed, as their exit status is lost
after cmd3 runs.
The toy example above is easy to spot because the "cmds" are
all the same length, but real code is much more complicated.
It's also difficult to detect these situations by statically
analyzing the shell code with regexps (like the
check-non-portable-shell script does); there's too much
context required to know whether a &&-chain is appropriate
on a given line or not.
This patch instead lets the shell check each test by
sticking a command with a specific and unusual return code
at the top of each test, like:
(exit 117) &&
cmd1 &&
cmd2
cmd3
In a well-formed test, the non-zero exit from the first
command prevents any of the rest from being run, and the
test's exit code is 117. In a bad test (like the one above),
the 117 is lost, and cmd3 is run.
When we encounter a failure of this check, we abort the test
script entirely. For one thing, we have no clue which subset
of the commands in the test snippet were actually run.
Running further tests would be pointless, because we're now
in an unknown state. And two, this is not a "test failure"
in the traditional sense. The test script is buggy, not the
code it is testing. We should be able to fix these problems
in the script once, and not have them come back later as a
regression in git's code.
After checking a test snippet for --chain-lint, we do still
run the test itself. We could actually have a pure-lint
mode which just checks each test, but there are a few
reasons not to. One, because the tests are executing
arbitrary code, which could impact the later environment
(e.g., that could impact which set of tests we run at all).
And two, because a pure-lint mode would still be expensive
to run, because a significant amount of code runs outside of
the test_expect_* blocks. Instead, this option is designed
to be used as part of a normal test suite run, where it adds
very little overhead.
Turning on this option detects quite a few problems in
existing tests, which will be fixed in subsequent patches.
However, there are a number of places it cannot reach:
- it cannot find a failure to break out of loops on error,
like:
cmd1 &&
for i in a b c; do
cmd2 $i
done &&
cmd3
which will not notice failures of "cmd2 a" or "cmd b"
- it cannot find a missing &&-chain inside a block or
subfunction, like:
foo () {
cmd1
cmd2
}
foo &&
bar
which will not notice a failure of cmd1.
- it only checks tests that you run; every platform will
have some tests skipped due to missing prequisites,
so it's impossible to say from one run that the test
suite is free of broken &&-chains. However, all tests get
run by _somebody_, so eventually we will notice problems.
- it does not operate on test_when_finished or prerequisite
blocks. It could, but these tends to be much shorter and
less of a problem, so I punted on them in this patch.
This patch was inspired by an earlier patch by Jonathan
Nieder:
rev-list: refuse --first-parent combined with --bisect
rev-list --bisect is used by git bisect, but never together with
--first-parent. Because rev-list --bisect together with --first-parent
is not handled currently, and even leads to segfaults, refuse to use
both options together.
Because this is not supported, it makes little sense to use git log
--bisect --first parent either, because refs/heads/bad is not limited to
the first parent chain.

fetch-pack: remove dead assignment to ref->new_sha1
In everything_local(), we used to assign the current ref's value
found in ref->old_sha1 to ref->new_sha1 when we already have all the
necessary objects to complete the history leading to that
commit. This copying was broken at 49bb805e (Do not ask for
objects known to be complete., 2005-10-19) and ever since we
instead stuffed a random bytes in ref->new_sha1 here. No
code complained or failed due to this breakage.
It turns out that no code path that comes after this
assignment even looks at ref->new_sha1 at all.
- The only caller of everything_local(), do_fetch_pack(),
returns this list of refs, whose element has bogus
new_sha1 values, to its caller. It does not look at the
elements itself, but does pass them to find_common, which
looks only at the name and old_sha1 fields.
- The only caller of do_fetch_pack(), fetch_pack(), returns this
list to its caller. It does not look at the elements nor act on
them.
- One of the two callers of fetch_pack() is cmd_fetch_pack(), the
top-level that implements "git fetch-pack". The only thing it
looks at in the elements of the returned ref list is the old_sha1
and name fields.
- The other caller of fetch_pack() is fetch_refs_via_pack() in the
transport layer, which is a helper that implements "git fetch".
It only cares about whether the returned list is empty (i.e.
failed to fetch anything).
Just drop the bogus assignment, that is not even necessary. The
remote-tracking refs are updated based on a different list and not
using the ref list being manipulated by this code path; the caller
do_fetch_pack() created a copy of that real ref list and passed the
copy down to this function, and modifying the elements here does not
affect anything.

If the server supports allow_tip_sha1_in_want, we add any
unmatched raw-sha1 entries in our "sought" list of refs to
the list of refs we will ask the other side for. We do so by
inserting the original "struct ref" directly into our list,
rather than making a copy. This has several problems.
The most minor problem is that one cannot ever free the
resulting list; it contains structs that are copies of the
remote refs (made earlier by fetch_pack) along with sought
refs that are referenced elsewhere.
But more importantly that we set the ref->next pointer to
NULL, chopping off the remainder of any existing list that
the ref was a part of. We get the set of "sought" refs in
an array rather than a linked list, but that array is often
in turn generated from a list. The test modification in
t5516 demonstrates this. Rather than fetching just an exact
sha1, we fetch that sha1 plus another ref:
- we build a linked list of refs to fetch when do_fetch
calls get_ref_map; the exact sha1 is first, followed by
the named ref ("refs/heads/extra" in this case).
- we pass that linked list to transport_fetch_ref, which
squashes it into an array of pointers
- that array goes to fetch_pack, which calls filter_ref.
There we generate the want list from a mix of what the
remote side has advertised, and the "sought" entry for
the exact sha1. We set the sought entry's "next" pointer
to NULL.
- after we return from transport_fetch_refs, we then try
to update the refs by following the linked list. But our
list is now truncated, and we do not update
refs/heads/extra at all.
We can fix this by making a copy of the ref. There's nothing
that fetch_pack does to it that must be reflected in the
original "sought" list (and indeed, if that were the case we
would have a serious bug, because it is only exact-sha1
entries which are treated this way).

filter_ref: avoid overwriting ref->old_sha1 with garbage
If the server supports allow_tip_sha1_in_want, then
fetch-pack's filter_refs function tries to check whether a
ref is a request for a straight sha1 by running:
if (get_sha1_hex(ref->name, ref->old_sha1))
...
I.e., we are using get_sha1_hex to ask "is this ref name a
sha1?". If it is true, then the contents of ref->old_sha1
will end up unchanged. But if it is false, then get_sha1_hex
makes no guarantees about what it has written. With a ref
name like "abcdefoo", we would overwrite 3 bytes of
ref->old_sha1 before realizing that it was not a sha1.
This is likely not a problem in practice, as anything in
refs->name (besides a sha1) will start with "refs/", meaning
that we would notice on the first character that there is a
problem. Still, we are making assumptions about the state
left in the output when get_sha1_hex returns an error (e.g.,
it could start from the end of the string, or error check
the values only once they were placed in the output). It's
better to be defensive.
We could just check that we have exactly 40 characters of
sha1. But let's be even more careful and make sure that we
have a 40-char hex refname that matches what is in old_sha1.
This is perhaps overly defensive, but spells out our
assumptions clearly.

If clone fails, we generally try to clean up any directories
we've created. We do this by installing an atexit handler,
so that we don't have to manually trigger cleanup. However,
since we install this after touching the filesystem, any
errors between our initial mkdir() and our atexit() call
will result in us leaving a crufty directory around.
We can fix this by moving our atexit() call earlier. It's OK
to do it before the junk_work_tree variable is set, because
remove_junk makes sure the variable is initialized. This
means we "activate" the handler by assigning to the
junk_work_tree variable, which we now bump down to just
after we call mkdir(). We probably do not want to do it
before, because a plausible reason for mkdir() to fail is
EEXIST (i.e., we are racing with another "git init"), and we
would not want to remove their work.
OTOH, this is probably not that big a deal; we will allow
cloning into an empty directory (and skip the mkdir), which
is already racy (i.e., one clone may see the other's empty
dir and start writing into it). Still, it does not hurt to
err on the side of caution here.
Note that writing into junk_work_tree and junk_git_dir after
installing the handler is also technically racy, as we call
our handler on an async signal. Depending on the platform,
we could see a sheared write to the variables. Traditionally
we have not worried about this, and indeed we already do
this later in the function. If we want to address that, it
can come as a separate topic.

Right now we return a NULL "struct sha1file" if we encounter
an error. However, the sole caller (write_idx_file) does not
check the return value, and will segfault if we hit this
case.
One option would be to handle the error in the caller.
However, there's really nothing for it to do but die. This
code path is hit during "git index-pack --verify"; after we
verify the packfile, we check that the ".idx" we would
generate from it is byte-wise identical to what is on disk.
We hit the error (and segfault) if we can't open the .idx
file (a likely cause of this is that somebody else ran "git
repack -ad" while we were verifying). Since we can't
complete the requested verification, we really have no
choice but to die.
Furthermore, the rest of the sha1fd_* functions simply die
on errors. So if were to open the file successfully, for
example, and then hit a read error, sha1write would call
die() for us. So pushing the die() down into sha1fd_check
keeps the interface consistent.

If several gitk instances are closed simultaneously, the savestuff
procedure can run at the same time, resulting in a conflict which may
cause losing of some of the instance's changes, failing the saving
operation or even corrupting the configuration file. This can happen,
for example, at user session closing, or at group closing of all
instances of an application which is possible in some desktop
environments.
To avoid this, make sure that only one saving operation is in
progress. It is guarded by existence of the $config_file_tmp
file. Creating the file and moving it to $config_file are both atomic
operations, so it should be reliable.
Reading does not need to be syncronized, because moving is an atomic
operation, and the $config_file always refers to a full and correct file.
But, if there is a stale $config_file_tmp file, report it at gitk start.
If such file is detected when saving, just report it abort the save, as

When gitk contains some changed parameter, and there is an existing
instance of gitk where the parameter is still old, it is reverted to
that old value when that instance exits.
Instead, store a parameter in config only if it has been modified in
the exiting instance. Otherwise, preserve the value which currently is in
file. This allows editing the configuration when several instances are
running, without rollback of the modification if some other
instance where the configuration was not edited is closed last.
For scalar variables, use trace(3tcl) to detect their change. Since
`trace` can send bogus events, doublecheck if the value has really
been changed, but once it is marked as changed, do not reset it back
to unchanged ever, because if user has restored the original value,
it's the decision which should be stored as well as modified value.
Treat view list especially: instead of rewriting the whole list, merge
individual views. Place old and updated views in their old places,
add new ones to the end of list. Collect modified views explicitly, in
newviewok{} and delview{}.
Do not merge geometry values. They are almost always changing because
user moves and resises windows, and there is no way to find which one of

contrib/completion: escape the forward slash in __git_match_ctag
The current definition results in an incorrect expansion of the term under zsh.
For instance "/^${1////\\/}/" under zsh with the argument "hi" results in:
/^/\/h/\/i/
This results in an output similar to this when trying to complete `git grep
chartab` under zsh:
:: git grep chartabawk: cmd. line:1: /^/\/c/\/h/\/a/\/r/\/t/\/a/\/b/ { print $1 }
awk: cmd. line:1: ^ backslash not last character on line
awk: cmd. line:1: /^/\/c/\/h/\/a/\/r/\/t/\/a/\/b/ { print $1 }
awk: cmd. line:1: ^ syntax error
Leaving the prompt in a goofy state until the user hits a key.
Escaping the literal / in the parameter expansion (using "/^${1//\//\\/}/")
results in:
/^chartab/
allowing the completion to work correctly.
This formulation also works under bash.

We create 50,000 tags to check that we don't overflow the
command-line of fetch-pack. But by using run_with_cmdline_limit,
we can get the same effect with a much smaller number of
tags. This makes the test fast enough that we can drop the
EXPENSIVE prereq, which means people will actually run it.
It was not documented to do so, but this test was also the
only test of a clone-over-http that requires multiple POSTs
during the conversation. We can continue to test that by
dropping http.postbuffer to its minimum size, and checking
that we get two POSTs.

you may get test failures, because some tests capture and
check the stderr output from git commands (and with
GIT_TRACE set to 1, the trace output will be included
there).
When we see GIT_TRACE set like this, we print a warning to
the user. However, we can do even better than that by just
pointing it to descriptor 4, which all tests leave connected
to the test script's stderr. That's likely what the user
intended (and any scripts that do want to see GIT_TRACE
output will set GIT_TRACE themselves).
Not only does this avoid false negatives in the tests, but
it means the user will actually see trace output for git
calls that redirect their stderr (whereas before, it was
sometimes confusingly buried in a file).

Right now if a test script receives SIGINT (e.g., because a
test was hanging and the user hit ^C), the shell exits
immediately. This can be annoying if the test script did any
global setup, like starting apache or git-daemon, as it will
not have an opportunity to clean up after itself. A
subsequent run of the test won't be able to start its own
daemon, and will either fail or skip the tests.
Instead, let's trap SIGINT to make sure we do a clean
shutdown, and just chain it to a normal exit (which will
trigger any cleanup).

upload-pack: do not check NULL return of lookup_unknown_object
We check whether the return value of lookup_unknown_object
is NULL, but some code paths dereference it before our
check. This turns out not to be capable of causing a
segfault, though. The lookup_unknown_object function will
never return NULL, since the whole point is to allocate an
object struct if it does not find an existing one. So the
code here is not wrong, it is just confusing. Let's just
drop the NULL check.

upload-pack: fix transfer.hiderefs over smart-http
When upload-pack advertises the refs (either for a normal,
non-stateless request, or for the initial contact in a
stateless one), we call for_each_ref with the send_ref
function as its callback. send_ref, in turn, calls
mark_our_ref, which checks whether the ref is hidden, and
sets OUR_REF or HIDDEN_REF on the object as appropriate. If
it is hidden, mark_our_ref also returns "1" to signal
send_ref that the ref should not be advertised.
If we are not advertising refs, (i.e., the follow-up
invocation by an http client to send its "want" lines), we
use mark_our_ref directly as a callback to for_each_ref. Its
marking does the right thing, but when it then returns "1"
to for_each_ref, the latter interprets this as an error and
stops iterating. As a result, we skip marking all of the
refs that come lexicographically after it. Any "want" lines
from the client asking for those objects will fail, as they
were not properly marked with OUR_REF.
To solve this, we introduce a wrapper callback around
mark_our_ref which always returns 0 (even if the ref is
hidden, we want to keep iterating). We also tweak the
signature of mark_our_ref to exclude unnecessary parameters
that were present only to conform to the callback interface.
This should make it less likely for somebody to accidentally
use it as a callback in the future.

Move the variables related to the client-supplied hostname into its own

The lifetime of the variables is easier to see this way. Allocated
memory is released within execute(). The strbufs don't have to be reset
anymore because they are written to only once at most: parse_host_arg()
is only called once by execute() and lookup_hostname() guards against
being called twice using hostname_lookup_done.
