After "git branch --move" of the currently checked out branch, the
code to walk the reflog of HEAD via "log -g" and friends
incorrectly stopped at the reflog entry that records the renaming
of the branch.
* jk/reflog-walk-maint:
reflog-walk: include all fields when freeing complete_reflogs
reflog-walk: don't free reflogs added to cache
reflog-walk: duplicate strings in complete_reflogs list
reflog-walk: skip over double-null oid due to HEAD rename
|
|
When we encounter an error adding reflogs for a walk, we try
to free any logs we have read. But we didn't free all
fields, meaning that we could in theory leak all of the
"items" array (which would consitute the bulk of the
allocated memory).
This patch adds a helper which frees all of the entries and
uses it as appropriate.
As it turns out, the leak seems impossible to trigger with
the current code. Of the three error paths that free the
complete_reflogs struct, two only kick in when the items
array is empty, and the third was removed entirely in the
previous commit.
So this patch should be a noop in terms of behavior, but it
fixes a potential maintenance headache should anybody add a
new error path and copy the partial-free code. Which is
what happened in 5026b47175 (add_reflog_for_walk: avoid
memory leak, 2017-05-04), though its leaky call was the
third one that was recently removed.

The add_reflog_for_walk() function keeps a cache mapping
refnames to their reflog contents. We use a cached reflog
entry if available, and otherwise allocate and store a new
one.
Since 5026b47175 (add_reflog_for_walk: avoid memory leak,
2017-05-04), when we hit an error parsing a date-based
reflog spec, we free the reflog memory but leave the cache
entry pointing to the now-freed memory.
We can fix this by just leaving the memory intact once it
has made it into the cache. This may leave an unused entry
in the cache, but that's OK. And it means we also catch a
similar situation: we may not have allocated at all in this
invocation, but simply be pointing to a cached entry from a
previous invocation (which is relying on that entry being
present).
The new test in t1411 exercises this case and fails when run
with --valgrind or ASan.

As part of the add_reflog_to_walk() function, we keep a
string_list mapping refnames to their reflog contents. This
serves as a cache so that accessing the same reflog twice
requires only a single copy of the log in memory.
The string_list is initialized via xcalloc, meaning its
strdup_strings field is set to 0. But after inserting a
string into the list, we unconditionally call free() on the
string, leaving the list pointing to freed memory. If
another reflog is added (e.g., "git log -g HEAD HEAD"), then
the second one may have unpredictable results.
The extra free was added by 5026b47175 (add_reflog_for_walk:
avoid memory leak, 2017-05-04). Though if you look
carefully, you can see that the code was buggy even before
then. If we tried to read the reflogs by time but came up
with no entries, we exited with an error, freeing the string
in that code path. So the bug was harder to trigger, but
still there.
We can fix it by just asking the string list to make a copy
of the string. Technically we could fix the problem by not
calling free() on our string (and just handing over
ownership to the string list), but there are enough
conditionals that it's quite hard to figure out which code
paths need the free and which do not. Simpler is better
here.
The new test reliably shows the problem when run with
--valgrind or ASAN.

Since 39ee4c6c2f (branch: record creation of renamed branch
in HEAD's log, 2017-02-20), a rename on the currently
checked out branch will create two entries in the HEAD
reflog: one where the branch goes away (switching to the
null oid), and one where it comes back (switching away from
the null oid).
This confuses the reflog-walk code. When walking backwards,
it first sees the null oid in the "old" field of the second
entry. Thanks to the "root commit" logic added by 71abeb753f
(reflog: continue walking the reflog past root commits,
2016-06-03), we keep looking for the next entry by scanning
the "new" field from the previous entry. But that field is
also null! We need to go just a tiny bit further, and look
at its "old" field. But with the current code, we decide the
reflog has nothing else to show and just give up. To the
user this looks like the reflog was truncated by the rename
operation, when in fact those entries are still there.
This patch does the absolute minimal fix, which is to look
back that one extra level and keep traversing.
The resulting behavior may not be the _best_ thing to do in
the long run (for example, we show both reflog entries each
with the same commit id), but it's a simple way to fix the
problem without risking further regressions.

Git's source code assumes that unsigned long is at least as precise as
time_t. Which is incorrect, and causes a lot of problems, in particular
where unsigned long is only 32-bit (notably on Windows, even in 64-bit
versions).
So let's just use a more appropriate data type instead. In preparation
for this, we introduce the new `timestamp_t` data type.
By necessity, this is a very, very large patch, as it has to replace all
timestamps' data type in one go.
As we will use a data type that is not necessarily identical to `time_t`,
we need to be very careful to use `time_t` whenever we interact with the
system functions, and `timestamp_t` everywhere else.

If a repository contains more than one root commit, then its HEAD
reflog may contain multiple "creation events", i.e. entries whose
"from" value is the null sha1. Listing such a reflog currently stops
prematurely at the first such entry, even when the reflog still
contains older entries. This can scare users into thinking that their
reflog got truncated after 'git checkout --orphan'.
Continue walking the reflog past such creation events based on the
preceeding reflog entry's "new" value.
The test 'symbolic-ref writes reflog entry' in t1401-symbolic-ref
implicitly relies on the current behavior of the reflog walker to stop
at a root commit and thus to list only the reflog entries that are
relevant for that test. Adjust the test to explicitly specify the
number of relevant reflog entries to be listed.

"git reflog" incorrectly assumed that all objects that used to be
at the tip of a ref must be commits, which caused it to segfault.
* dk/reflog-walk-with-non-commit:
reflog-walk: don't segfault on non-commit sha1's in the reflog
|
|
git reflog (ab)uses the log machinery to display its list of log
entries. To do so it must fake commit parent information for the log
walker.
For refs in refs/heads this is no problem, as they should only ever
point to commits. Tags and other refs however can point to anything,
thus their reflog may contain non-commit objects.
To avoid segfaulting, we check whether reflog entries are commits before
feeding them to the log walker and skip any non-commits. This means that
git reflog output will be incomplete for such refs, but that's one step
up from segfaulting. A more complete solution would be to decouple git
reflog from the log walker machinery.

It's a common pattern to do:
foo = xmalloc(strlen(one) + strlen(two) + 1 + 1);
sprintf(foo, "%s %s", one, two);
(or possibly some variant with strcpy()s or a more
complicated length computation). We can switch these to use
xstrfmt, which is shorter, involves less error-prone manual
computation, and removes many sprintf and strcpy calls which
make it harder to audit the code for real buffer overflows.

In preparation for adding date modes that may carry extra
information beyond the mode itself, this patch converts the
date_mode enum into a struct.
Most of the conversion is fairly straightforward; we pass
the struct as a pointer and dereference the type field where
necessary. Locations that declare a date_mode can use a "{}"
constructor. However, the tricky case is where we use the
enum labels as constants, like:
show_date(t, tz, DATE_NORMAL);
Ideally we could say:
show_date(t, tz, &{ DATE_NORMAL });
but of course C does not allow that. Likewise, we cannot
cast the constant to a struct, because we need to pass an
actual address. Our options are basically:
1. Manually add a "struct date_mode d = { DATE_NORMAL }"
definition to each caller, and pass "&d". This makes
the callers uglier, because they sometimes do not even
have their own scope (e.g., they are inside a switch
statement).
2. Provide a pre-made global "date_normal" struct that can
be passed by address. We'd also need "date_rfc2822",
"date_iso8601", and so forth. But at least the ugliness
is defined in one place.
3. Provide a wrapper that generates the correct struct on
the fly. The big downside is that we end up pointing to
a single global, which makes our wrapper non-reentrant.
But show_date is already not reentrant, so it does not
matter.
This patch implements 3, along with a minor macro to keep
the size of the callers sane.

resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref
resolves successfully for writing but not for reading). Change this to be
a flags field instead, and pass the new constant RESOLVE_REF_READING when
we want this behaviour.
While at it, swap two of the arguments in the function to put output
arguments at the end. As a nice side effect, this ensures that we can
catch callers that were unaware of the new API so they can be audited.
Give the wrapper functions resolve_refdup and read_ref_full the same
treatment for consistency.

When we are showing reflog selectors during a walk, we infer
from context whether the user wanted to see the index in
each selector, or the reflog date. The current rules are:
1. if the user asked for an explicit date format in the
output, show the date
2. if the user asked for ref@{now}, show the date
3. if neither is true, show the index
However, if we see "ref@{0}", that should be a strong clue
that the user wants to see the counted version. In fact, it
should be much stronger than the date format in (1). The
user may have been setting the date format to use in another
part of the output (e.g., in --format="%gd (%ad)", they may
have wanted to influence the author date).
This patch flips the rules to:
1. if the user asked for ref@{0}, always show the index
2. if the user asked for ref@{now}, always show the date
3. otherwise, we have just "ref"; show them counted by
default, but respect the presence of "--date" as a clue
that the user wanted them date-based

When we prepare to walk a reflog, we parse the specification
and pull some information from it, such as which reflog to
look in (e.g., HEAD), and where to start (e.g., HEAD@{10} or
HEAD@{yesterday}). The resulting struct has a "recno" field
to show where in the reflog we are starting. It also has a
"flag" field; if true, it means the recno field came from
parsing a date like HEAD@{yesterday}.
There are two problems with this:
1. "flag" is an absolutely terrible name, as it conveys
nothing about the meaning
2. you can tell "HEAD" from "HEAD@{yesterday}", but you
can't differentiate "HEAD" from "HEAD{0}"
This patch converts the flag into a tri-state (and gives it

* jk/maint-reflog-bottom:
reflogs: clear flags properly in corner case
|
|
The reflog-walking mechanism is based on the regular
revision traversal. We just rewrite the parents of each
commit in fake_reflog_parent to point to the commit in the
next reflog entry instead of the real parents.
However, the regular revision traversal tries not to show
the same commit twice, and so sets the SHOWN flag on each
commit it shows. In a reflog, however, we may want to see
the same commit more than once if it appears in the reflog
multiple times (which easily happens, for example, if you do
a reset to a prior state).
The fake_reflog_parent function takes care of this by
clearing flags, including SHOWN. Unfortunately, it does so
at the very end of the function, and it is possible to
return early from the function if there is no fake parent to
set up (e.g., because we are at the very first reflog entry
on the branch). In such a case the flag is not cleared, and
the entry is skipped by the revision traversal machinery as
already shown.
You can see this by walking the log of a ref which is set to
its very first commit more than once (the test below shows
such a situation). In this case the reflog walk will fail to
show the entry for the initial creation of the ref.
We don't want to simply move the flag-clearing to the top of
the function; we want to make sure flags set during the
fake-parent installation are also cleared. Instead, let's
hoist the flag-clearing out of the fake_reflog_parent
function entirely. It's not really about fake parents
anyway, and the only caller is the get_revision machinery.

Add three new --pretty=format escapes:
%gD long reflog descriptor (e.g. refs/stash@{0})
%gd short reflog descriptor (e.g. stash@{0})
%gs reflog message
This is achieved by passing down the reflog info, if any, inside the
pretty_print_context struct.
We use the newly refactored get_reflog_selector(), and give it some
extra functionality to extract a shortened ref. The shortening is
cached inside the commit_reflogs struct; the only allocation of it
happens in read_complete_reflog(), where it is initialised to 0. Also
add another helper get_reflog_message() for the message extraction.
Note that the --format="%h %gD: %gs" tests may not work in real
repositories, as the --pretty formatter doesn't know to leave away the
": " on the last commit in an incomplete (because git-gc removed the
old part) reflog. This equivalence is nevertheless the main goal of
this patch.

The multiline reflog format (e.g., as shown by "git log -g")
will show HEAD@{<date>} rather than HEAD@{<count>} in two
situations:
1. If the user gave branch@{<date>} syntax to specify the
reflog
2. If the user gave a --date=<format> specifier
It uses the "normal" date format in case 1, and the
user-specified format in case 2.
The oneline reflog format (e.g., "git reflog show" or "git
log -g --oneline") will show the date in the same two
circumstances. However, it _always_ shows the date as a
relative date, and it always ignores the timezone.
In case 2, it seems ridiculous to trigger the date but use a
format totally different from what the user requested.
For case 1, it is arguable that the user might want to see
the relative date by default; however, the multiline version
shows the normal format.
This patch does three things:
- refactors the "relative_date" parameter to
show_reflog_message to be an actual date_mode enum,
since this is how it is used (it is passed to show_date)
- uses the passed date_mode parameter in the oneline
format (making it consistent with the multiline format)
- does not ignore the timezone parameter in oneline mode

The name path_list was correct for the first usage of that data structure,
but it really is a general-purpose string list.
$ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list)
$ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list)
$ git mv path-list.h string-list.h
$ git mv path-list.c string-list.c
$ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path)
$ perl -i -pe 's/path/string/g' string-list.[ch]
$ git mv Documentation/technical/api-path-list.txt \
Documentation/technical/api-string-list.txt
$ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths)
... and then fix all users of string-list to access the member "string"
instead of "path".
Documentation/technical/api-string-list.txt needed some rewrapping, too.

When asking "git log -g --all", clearly you want to see only those refs
that do have reflogs, but you do not want it to fail, either.
So instead of die()ing, complain about it, but move on to the other refs.

Since "git log origin/master" uses dwim_log() to match
"refs/remotes/origin/master", it makes sense to do that for
"git log --reflog", too.

If you say "git log -g --relative-date", it is very likely that
you want to see the reflog names in terms of a relative date.

In the context of reflog output the reflog message is more useful than
the commit message's first line. When relevant the reflog message
will contain that line anyway.

Now, "git log --abbrev-commit --pretty=o --walk-reflogs HEAD" is
reasonably pleasant to use.

Dependency on reflog-walk.h was missing in the Makefile, and
reflog-walk.c did not even include it.
