* jc/maint-reflog-bad-timestamp:
t0101: use a fixed timestamp when searching in the reflog
Update @{bogus.timestamp} fix not to die()
approxidate_careful() reports errorneous date string
|
|
For a long time, the time based reflog syntax (e.g. master@{yesterday})
didn't complain when the "human readable" timestamp was misspelled, as
the underlying mechanism tried to be as lenient as possible. The funny
thing was that parsing of "@{now}" even relied on the fact that anything
not recognized by the machinery returned the current timestamp.
Introduce approxidate_careful() that takes an optional pointer to an
integer, that gets assigned 1 when the input does not make sense as a
timestamp.
As I am too lazy to fix all the callers that use approxidate(), most of
the callers do not take advantage of the error checking, but convert the
code to parse reflog to use it as a demonstration.
Tests are mostly from Jeff King.

This has the same effect as --no-replace-objects option; git ignores the
replace refs. When --no-replace-objects option is passed to git, this
environment variable is set to "1" and exported to subprocesses in order
to propagate the same setting.
It is useful for example for scripts, as the git commands used in them can
now be aware that they must not read replace refs.

Expose the command used by launch_editor() for scripts to use.
This should allow one to avoid searching for a proper editor
separately in each command.
git_editor(void) uses the logic to decide which editor to use
that used to live in launch_editor(). The function returns NULL
if there is no suitable editor; the caller is expected to issue
an error message when appropriate.
launch_editor() uses git_editor() and gives the error message the
same way as before when EDITOR is not set.
"git var GIT_EDITOR" gives the editor name, or an error message
when there is no appropriate one.
"git var -l" gives GIT_EDITOR=name only if there is an
appropriate editor.

Eons ago HPA taught git-daemon how to protect itself from /../
attacks, which Junio brought back into service in d79374c7b58d
("daemon.c and path.enter_repo(): revamp path validation").
I did not carry this into git-http-backend as originally we relied
only upon PATH_TRANSLATED, and assumed the HTTP server had done
its access control checks to validate the resolved path was within
a directory permitting access from the remote client. This would
usually be sufficient to protect a server from requests for its
/etc/passwd file by http://host/smart/../etc/passwd sorts of URLs.
However in 917adc036086 Mark Lodato added GIT_PROJECT_ROOT as an
additional method of configuring the CGI. When this environment
variable is used the web server does not generate the final access
path and therefore may blindly pass through "/../etc/passwd"
in PATH_INFO under the assumption that "/../" might have special
meaning to the invoked CGI.
Instead of permitting these sorts of malformed path requests, we
now reject them back at the client, with an error message for the
server log. This matches git-daemon behavior.

retired git-clone-pack in commit efc7fa53. Since then the only

used by the fetch-pack/upload-pack protocol we should move it back
to be a private detail of fetch-pack.

Commit notes are blobs which are shown together with the commit
message. These blobs are taken from the notes ref, which you can
configure by the config variable core.notesRef, which in turn can
be overridden by the environment variable GIT_NOTES_REF.
The notes ref is a branch which contains "files" whose names are
the names of the corresponding commits (i.e. the SHA-1).
The rationale for putting this information into a ref is this: we
want to be able to fetch and possibly union-merge the notes,
maybe even look at the date when a note was introduced, and we
want to store them efficiently together with the other objects.
This patch has been improved by the following contributions:
- Thomas Rast: fix core.notesRef documentation
- Tor Arne Vestbø: fix printing of multi-line notes
- Alex Riesen: Using char array instead of char pointer costs less BSS
- Johan Herland: Plug leak when msg is good, but msglen or type causes return

A local clone without hardlinks copies all objects, including dangling
ones, to the new repository. Since the mtimes are renewed, those
dangling objects cannot be pruned by "git gc --prune", even if they
would have been old enough for pruning in the original repository.
Instead, preserve mtime during copy. "git gc --prune" will then work
in the clone just like it did in the original.

In 2d14d65 (Use a clearer style to issue commands to remote helpers,
2009-09-03) I happened to notice two changes like this:
- write_in_full(helper->in, "list\n", 5);
+
+ strbuf_addstr(&buf, "list\n");
+ write_in_full(helper->in, buf.buf, buf.len);
+ strbuf_reset(&buf);
IMHO, it would be better to define a new function,
static inline ssize_t write_str_in_full(int fd, const char *str)
{
return write_in_full(fd, str, strlen(str));
}
and then use it like this:
- strbuf_addstr(&buf, "list\n");
- write_in_full(helper->in, buf.buf, buf.len);
- strbuf_reset(&buf);
+ write_str_in_full(helper->in, "list\n");
Thus not requiring the added allocation, and still avoiding
the maintenance risk of literal string lengths.
These days, compilers are good enough that strlen("literal")
imposes no run-time cost.
Transformed via this:
perl -pi -e \
's/write_in_full\((.*?), (".*?"), \d+\)/write_str_in_full($1, $2)/'\
$(git grep -l 'write_in_full.*"')

This message is designed to help new users understand what

making it harder to see.

optional messages, with this push message as the first

People who configured trailing-space depended on it to catch both extra
white space at the end of line, and extra blank lines at the end of file.
Earlier attempt to introduce only blank-at-eof gave them an escape hatch
to keep the old behaviour, but it is a regression until they explicitly
specify the new error class.
This introduces a blank-at-eol that only catches extra white space at the
end of line, and makes the traditional trailing-space a convenient synonym
to catch both blank-at-eol and blank-at-eof. This way, people who used
trailing-space continue to catch both classes of errors.

"git apply" strips new blank lines at EOF under --whitespace=fix option,
but neigher --whitespace=warn nor --whitespace=error paid any attention to
these errors.
Introduce a new whitespace error class, blank-at-eof, to make the
whitespace error handling more consistent.
The patch adds a new "linenr" field to the struct fragment in order to
record which line the hunk started in the input file, but this is needed
solely for reporting purposes. The detection of this class of whitespace
errors cannot be done while parsing a patch like we do for all the other
classes of whitespace errors. It instead has to wait until we find where
to apply the hunk, but at that point, we do not have an access to the
original line number in the input file anymore, hence the new field.
Depending on your point of view, this may be a bugfix that makes warn and
error in line with fix. Or you could call it a new feature. The line
between them is somewhat fuzzy in this case.
Strictly speaking, triggering more errors than before is a change in
behaviour that is not backward compatible, even though the reason for the
change is because the code was not checking for an error that it should
have. People who do not want added blank lines at EOF to trigger an error
can disable the new error class.

git apply: option to ignore whitespace differences
|

Merlyn noticed that Documentation/install-doc-quick.sh no longer correctly
removes old installed documents when the target directory has a leading
path that is a symlink. It turns out that "checkout-index --prefix" was
broken by recent b6986d8 (git-checkout: be careful about untracked
symlinks, 2009-07-29).
I suspect has_symlink_leading_path() could learn the third parameter
(prefix that is allowed to be symlinked directories) to allow us to retire
a similar function has_dirs_only_path().
Another avenue of fixing this I considered was to get rid of base_dir and
base_dir_len from "struct checkout", and instead make "git checkout-index"
when run with --prefix mkdir the leading path and chdir in there. It
might be the best longer term solution to this issue, as the base_dir
feature is used only by that rather obscure codepath as far as I know.
But at least this patch should fix this breakage.

Add a test showing that 'git repack' throws away grafted-away parents
Conflicts:
git-repack.sh

When you have grafts that pretend that a given commit has different
parents than the ones recorded in the commit object, it is dangerous
to let 'git repack' remove those hidden parents, as you can easily
remove the graft and end up with a broken repository.
So let's play it safe and keep those parent objects and everything
that is reachable by them, in addition to the grafted parents.
As this behavior can only be triggered by git pack-objects, and as that
command handles duplicate parents gracefully, we do not bother to cull
duplicated parents that may result by using both true and grafted
parents.

It seems that accessing NTFS partitions with ufsd (at least on my EeePC)
has an unnerving bug: if you link() a file and unlink() it right away,
the target of the link() will have the correct size, but consist of NULs.
It seems as if the calls are simply not serialized correctly, as single-stepping
through the function move_temp_to_file() works flawlessly.
As ufsd is "Commertial software" (sic!), I cannot fix it, and have to work
around it in Git.
At the same time, it seems that this fixes msysGit issues 222 and 229 to
assume that Windows cannot handle link() && unlink().
