t: make 'test_i18ngrep' more informative on failure

When 'test_i18ngrep' can't find the expected pattern, it exits
completely silently; when its negated form does find the pattern that
shouldn't be there, it prints the matching line(s) but otherwise exits
without any error message.  This leaves the developer puzzled about
what could have gone wrong.

Make 'test_i18ngrep' more informative on failure by printing an error
message including the invoked 'grep' command and the contents of the
file it had to scan through.

Note that this "dump the scanned file" part is not quite perfect, as
it dumps only the file specified as the function's last positional
parameter, thus assuming that there is only a single file parameter.
I think that's a reasonable assumption to make, one that holds true in
the current code base.  And even if someone were to scan multiple
files at once in the future, the worst thing that could happen is that
the verbose error message won't include the contents of all those
files, only the last one.  Alas, we can't really do any better than
this, because checking whether the other positional parameters match a
filename can result in false positives: 't3400-rebase.sh' and
't3404-rebase-interactive.sh' contain one test each, where the
'test_i18ngrep's pattern verbatimly matches a file in the trash
directory.

6 years agot: validate 'test_i18ngrep's parameters
SZEDER Gábor [Thu, 8 Feb 2018 15:56:55 +0000 (16:56 +0100)] 
t: validate 'test_i18ngrep's parameters

Some of the previous patches in this series fixed bogus
'test_i18ngrep' invocations:

  - Two invocations where the tested git command's standard output is
    directly piped into 'test_i18ngrep'.  While convenient, this is an
    antipattern, because the pipe hides the git command's exit code,
    and the test could continue even if the command exited with error.

  - Two invocations that had neither a filename parameter nor anything
    piped into their standard input, yet both managed to remain
    unnoticed for years.  A third similarly bogus invocation is
    currently lurking in 'pu' for a couple of weeks now.

Prevent similar mistakes in the future by validating 'test_i18ngrep's
parameters requiring that

  - The last parameter names an existing file to be read, effectively
    forbidding piping into 'test_i18ngrep'.

    Note that this change will also forbid cases where 'test_i18ngrep'
    would legitimately read its standard input, e.g. when its standard
    input is redirected from a file, or when a git command's standard
    output is first written to an intermediate file, which is then
    preprocessed by a non-git command before the results are piped
    into 'test_i18ngrep'.  See two of the previous patches for the
    only such cases we had in our test suite.  However, reliably
    preventing the piping antipattern is arguably more important than
    supporting these cases, which can be easily worked around by
    opening the file directly or using an intermediate file anyway.

  - There are at least two parameters, not including the optional '!'
    to negate the pattern.  This ought to catch corner cases when
    'test_i18ngrep' looks for the name of an existing file on its
    standard input; the above check would miss this case becase the
    filename as pattern would be the last parameter.

    Note that this is not quite perfect, as it doesn't account for any
    'grep --options' given as parameters.  However, doing so would be
    far too complicated, considering that patterns can start with
    dashes as well, and in the majority of the cases we don't use any
    such options anyway.

blame: tighten command line parser

The command line parser of "git blame" is prepared to take an
ancient odd argument order "blame <path> <rev>" in addition to the
usual "blame [<rev>] <path>".  It has at least two negative
ramifications:

 - In order to tell these two apart, it checks if the last command
   line argument names a path in the working tree, using
   file_exists().  However, "blame <rev> <path>" is a request to
   explain each and every line in the contents of <path> stored in
   revision <rev> and does not need to have a working tree version
   of the file.  A check with file_exists() is simply wrong.

 - To coerce that mistaken file_exists() check to work, the code
   calls setup_work_tree() before doing so, because the path it has
   is relative to the top-level of the project tree.  However,
   "blame <rev> <path>" MUST be usable even in a bare repository,
   and there is no reason for letting setup_work_tree() complain
   and die with "This operation must be run in a work tree".

To correct the former, switch to check if the last token is a
revision (and if so, parse arguments using "blame <path> <rev>"
rule).  Correct the latter by getting rid of setup_work_tree() and
file_exists() check--the only case the call to this function matters
is when we are running "blame <path>" (i.e. no starting revision and
asking to blame the working tree file at <path>, digging through the
HEAD revision), but there is a call in setup_scoreboard() just

dir.c: ignore paths containing .git when invalidating untracked cache

read_directory() code ignores all paths named ".git" even if it's not
a valid git repository. See treat_path() for details. Since ".git" is
basically invisible to read_directory(), when we are asked to
invalidate a path that contains ".git", we can safely ignore it
because the slow path would not consider it anyway.

This helps when fsmonitor is used and we have a real ".git" repo at
worktree top. Occasionally .git/index will be updated and if the
fsmonitor hook does not filter it, untracked cache is asked to
invalidate the path ".git/index".

Without this patch, we invalidate the root directory unncessarily,
which:

- makes read_directory() fall back to slow path for root directory
  (slower)

- makes the index dirty (because UNTR extension is updated). Depending
  on the index size, writing it down could also be slow.

A note about the new "safe_path" knob. Since this new check could be
relatively expensive, avoid it when we know it's not needed. If the
path comes from the index, it can't contain ".git". If it does
contain, we may be screwed up at many more levels, not just this one.

daemon: add --log-destination=(stderr|syslog|none)

This new option can be used to override the implicit --syslog of
--inetd, or to disable all logging. (While --detach also implies
--syslog, --log-destination=stderr with --detach is useless since
--detach disassociates the process from the original stderr.) --syslog
is retained as an alias for --log-destination=syslog.

--log-destination always overrides implicit --syslog regardless of
option order. This is different than the “last one wins” logic that
applies to some implicit options elsewhere in Git, but should hopefully
be less confusing. (I also don’t know if *all* implicit options in Git
follow “last one wins”.)

The combination of --inetd with --log-destination=stderr is useful, for
instance, when running `git daemon` as an instanced systemd service
(with associated socket unit). In this case, log messages sent via
syslog are received by the journal daemon, but run the risk of being
processed at a time when the `git daemon` process has already exited
(especially if the process was very short-lived, e.g. due to client
error), so that the journal daemon can no longer read its cgroup and
attach the message to the correct systemd unit (see systemd/systemd#2913
[1]). Logging to stderr instead can solve this problem, because systemd
can connect stderr directly to the journal daemon, which then already
knows which unit is associated with this stream.

reset --hard: make use of the pretty machinery

reset --hard currently uses its own logic for printing the first line of
the commit message in its output.  Instead of just using the first line,
use the pretty machinery to create the output.

In addition to the easier to follow code, this makes the output more
consistent with other commands that print the title of the commit, such
as 'git commit --oneline' or 'git checkout', which both use
'pp_commit_easy()' with the CMIT_FMT_ONELINE modifier.

It is a slight change of the output if the second line of the commit
message is not a blank line, i.e. if the commit message is

    foo
    bar

previously we would print "HEAD is now at 000000 foo", while after
this change we print "HEAD is now at 000000 foo bar", same as 'git log
--oneline' shows "000000 foo bar".

So this does make the output more consistent with other commands, and
'reset' is a porcelain command, so nobody should be parsing the output
in scripts.

The current behaviour dates back to 0e5a7faa3a ("Make "git reset" a
builtin.", 2007-09-11), so I assume (without digging into the old
codebase too much) that the logic was implemented because there was
no convenience function such as 'pp_commit_easy' that would do this
already.
