"git status" has trouble showing where it came from by interpreting
reflog entries that recordcertain events, e.g. "checkout @{u}", and
gives a hard/fatal error. Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error to allow "status" show its
output.
* jt/interpret-branch-name-fallback:
wt-status: tolerate dangling marks
refs: move dwim_ref() to header file
sha1-name: replace unsigned int with option struct
|

When a user checks out the upstream branch of HEAD, the upstream branch
not being a local branch, and then runs "git status", like this:
git clone $URL client
cd client
git checkout @{u}
git status
no status is printed, but instead an error message:
fatal: HEAD does not point to a branch
(This error message when running "git branch" persists even after
checking out other things - it only stops after checking out a branch.)
This is because "git status" reads the reflog when determining the "HEAD
detached" message, and thus attempts to DWIM "@{u}", but that doesn't
work because HEAD no longer points to a branch.
Therefore, when calculating the status of a worktree, tolerate dangling
marks. This is done by adding an additional parameter to
dwim_ref() and repo_dwim_ref().

The dir structure seemed to have a number of leaks and problems around
it. First I noticed that parent_hashmap and recursive_hashmap were
being leaked (though Peff noticed and submitted fixes before me). Then
I noticed in the previous commit that clear_directory() was only taking
responsibility for a subset of fields within dir_struct, despite the
fact that entries[] and ignored[] we allocated internally to dir.c.
That, of course, resulted in many callers either leaking or haphazardly
trying to free these arrays and their contents.
Digging further, I found that despite the pretty clear documentation
near the top of dir.h that folks were supposed to call clear_directory()
when the user no longer needed the dir_struct, there were four callers
that didn't bother doing that at all. However, two of them clearly
thought about leaks since they had an UNLEAK(dir) directive, which to me
suggests that the method to free the data was too unclear. I suspect
the non-obviousness of the API and its holes led folks to avoid it,
which then snowballed into further problems with the entries[],
ignored[], parent_hashmap, and recursive_hashmap problems.
Rename clear_directory() to dir_clear() to be more in line with other
data structures in git, and introduce a dir_init() to handle the
suggested memsetting of dir_struct to all zeroes. I hope that a name
like "dir_clear()" is more clear, and that the presence of dir_init()
will provide a hint to those looking at the code that they need to look
for either a dir_clear() or a dir_free() and lead them to find
dir_clear().

The calling convention for the dir API is supposed to end with a call to
clear_directory() to free up no longer needed memory. However,
clear_directory() didn't free dir->entries or dir->ignored. I believe
this was an oversight, but a number of callers noticed memory leaks and
started free'ing these. Unfortunately, they did so somewhat haphazardly
(sometimes freeing the entries in the arrays, and sometimes only
free'ing the arrays themselves). This suggests the callers weren't
trying to make sure any possible memory used might be free'd, but just
the memory they noticed their usecase definitely had allocated.
Fix this mess by moving all the duplicated free'ing logic into
clear_directory(). End by resetting dir to a pristine state so it could
be reused if desired.

The argv_array API is useful for not just managing argv but any
"vector" (NULL-terminated array) of strings, and has seen adoption
to a certain degree. It has been renamed to "strvec" to reduce the
barrier to adoption.
* jk/strvec:
strvec: rename struct fields
strvec: drop argv_array compatibility layer
strvec: update documention to avoid argv_array
strvec: fix indentation in renamed calls
strvec: convert remaining callers away from argv_array name
strvec: convert more callers away from argv_array name
strvec: convert builtin/ callers away from argv_array name
quote: rename sq_dequote_to_argv_array to mention strvec
strvec: rename files from argv-array to strvec
argv-array: rename to strvec
argv-array: use size_t for count and alloc
|
|
Code which split an argv_array call across multiple lines, like:
argv_array_pushl(&args, "one argument",
"another argument", "and more",
NULL);
was recently mechanically renamed to use strvec, which results in
mis-matched indentation like:
strvec_pushl(&args, "one argument",
"another argument", "and more",
NULL);
Let's fix these up to align the arguments with the opening paren. I did
this manually by sifting through the results of:
git jump grep 'strvec_.*,$'
and liberally applying my editor's auto-format. Most of the changes are
of the form shown above, though I also normalized a few that had
originally used a single-tab indentation (rather than our usual style of
aligning with the open paren). I also rewrapped a couple of obvious
cases (e.g., where previously too-long lines became short enough to fit
on one), but I wasn't aggressive about it. In cases broken to three or
more lines, the grouping of arguments is sometimes meaningful, and it
wasn't worth my time or reviewer time to ponder each case individually.

We eventually want to drop the argv_array name and just use strvec
consistently. There's no particular reason we have to do it all at once,
or care about interactions between converted and unconverted bits.
Because of our preprocessor compat layer, the names are interchangeable
to the compiler (so even a definition and declaration using different
names is OK).
This patch converts all of the remaining files, as the resulting diff is
reasonably sized.
The conversion was done purely mechanically with:
git ls-files '*.c' '*.h' |
xargs perl -i -pe '
s/ARGV_ARRAY/STRVEC/g;
s/argv_array/strvec/g;
'
We'll deal with any indentation/style fallouts separately.

Some of the early feedback of folks trying out sparse-checkouts at
$dayjob is that sparse checkouts can sometimes be disorienting; users
can forget that they had a sparse-checkout and then wonder where files
went. Add some output to 'git status' in the form of a simple line that
states:
You are in a sparse checkout with 35% of files present.
where, obviously, the exact figure changes depending on what percentage
of files from the index do not have the SKIP_WORKTREE bit set.

Traditionally, the expected calling convention for the dir.c API was:
fill_directory(&dir, ..., pathspec)
foreach entry in dir->entries:
if (dir_path_match(entry, pathspec))
process_or_display(entry)
This may have made sense once upon a time, because the fill_directory() call
could use cheap checks to avoid doing full pathspec matching, and an external
caller may have wanted to do other post-processing of the results anyway.
However:
* this structure makes it easy for users of the API to get it wrong
* this structure actually makes it harder to understand
fill_directory() and the functions it uses internally. It has
tripped me up several times while trying to fix bugs and
restructure things.
* relying on post-filtering was already found to produce wrong
results; pathspec matching had to be added internally for multiple
cases in order to get the right results (see commits 404ebceda01c
(dir: also check directories for matching pathspecs, 2019-09-17)
and 89a1f4aaf765 (dir: if our pathspec might match files under a
dir, recurse into it, 2019-09-17))
* it's bad for performance: fill_directory() already has to do lots
of checks and knows the subset of cases where it still needs to do
more checks. Forcing external callers to do full pathspec
matching means they must re-check _every_ path.
So, add the pathspec matching within the fill_directory() internals, and
remove it from external callers.

Before this patch, "git branch" would put "(HEAD detached...)" and "(no
branch, rebasing...)" lines before all the other branches *in most
cases* except for when using Chinese-language messages. zh_CN generally
uses a full-width "(" symbol (codepoint FF08) to match the full-width
proportions of Chinese characters, and the translated strings we had did
use them. This meant that the detached HEAD line would appear after all
local refs and even after the remote refs if there were any.
AFAIK, it is sometimes not jarring to see the half-width parenthesis in
"full-width" text as in the CJK languages, for instance when there are
no characters preceding or following the parenthesized text fragment. By
removing the parenthesis from the localizable text, we can share strings
with wt-status.c and remove a cautionary comment to translators.
Remove the ( from the localizable portion of messages so the sorting
happens properly regardless of locale.

The new command "git restore" (together with "git switch") are added
to avoid the confusion of one-command-do-all "git checkout" for new

For these reasons, promote it everywhere possible. This includes
documentation, suggestions/advice from other commands.
One nice thing about git-restore is the ability to restore
"everything", so it can be used in "git status" advice instead of both
"git checkout" and "git reset". The three commands suggested by "git
status" are add, rm and restore.
"git checkout" is also removed from "git help" (i.e. it's no longer

In ref-filter.c, when processing the atom %(push:track), the
ahead/behind values are computed using `stat_tracking_info` which refers
to the upstream branch.
Fix that by introducing a new flag `for_push` in `stat_tracking_info`
in remote.c, which does the same thing but for the push branch.
Update the few callers of `stat_tracking_info` to handle this flag. This
ensure that whenever we use this function in the future, we are careful
to specify is this should apply to the upstream or the push branch.
This bug was not detected in t/t6300-for-each-ref.sh because in the test
for push:track, both the upstream and the push branches were behind by 1
from the local branch. Change the test so that the upstream branch is
behind by 1 while the push branch is ahead by 1. This allows us to test
that %(push:track) refers to the correct branch.
This changes the expected value of some following tests (by introducing
new references), so update them too.

Status variables were initialized in the collect phase and some
variables were later freed in the print functions.
A "struct wt_status" used to be sufficient for the output phase to
work. It was designed to be filled in the collect phase and consumed
in the output phase, but over time some fields were added and output
phase started filling the fields.
A "struct wt_status_state" that was used in other codepaths turned out
to be useful in the "git status" output. This is not tied to "struct
wt_status", so filling in the collect phase was not consistently
followed.
Move the status state structure variables into the status state
structure and populate them in the collect functions.
Create a new function to free the buffers that were being freed in the
print function. Call this new function in commit.c where both the
collect and print functions were being called.

In an update to fix a bug with "commit --dry-run" it was found that
the committable flag was broken. The update was, at the time, accepted
as it was better than the previous version. [1]
Since the setting of the committable flag had been done in
wt_longstatus_print_updated, move it to wt_status_collect_updated_cb.
Set the committable flag in wt_status_collect_changes_initial to keep
from introducing a rebase regression.
Instead of setting the committable flag in show_merge_in_progress, in
wt_status_cllect check for a merge that has not been committed. If
present then set the committable flag.
Change the tests to expect success since updates to the wt-status
broken code section is being fixed.

noop with respect to the generated code.
The result is also perhaps a little more readable, as it
avoids the "zero is equal" idiom. Since it's so prevalent in
C, I think seasoned programmers tend not to even notice it
anymore, but it can sometimes make for awkward double
negations (e.g., we can drop a few !!oidcmp() instances
here).
This patch was generated almost entirely by the included
coccinelle patch. This mechanical conversion should be
completely safe, because we check explicitly for cases where
oidcmp() is compared to 0, which is what oideq() is doing
under the hood. Note that we don't have to catch "!oidcmp()"
separately; coccinelle's standard isomorphisms make sure the
two are treated equivalently.
I say "almost" because I did hand-edit the coccinelle output
to fix up a few style violations (it mostly keeps the
original formatting, but sometimes unwraps long lines).

Make the match_patchspec API and friends take an index_state instead
of assuming the_index in dir.c. All external call sites are converted
blindly to keep the patch simple and retain current behavior.
Individual call sites may receive further updates to use the right
index instead of the_index.
