Description
Issue: https://gitlab.com/gitlab-org/gitlab/-/issues/228729
In this video we try to find a commit that might have fixed this issue using `git bisect` and the power of binary search!
A
B
B
Not
to
go
to
my
emails
or
something
like
that:
okay,
something
really
cool,
because
we
had
something
that
broke
and
obviously
broke
accidentally,
but
then
it
was
fixed
accidentally,
we
kind
of
would
like
to
know.
What's
going
on
so
mark
is
showing
how
we
can
use
get
bisect
so
that
it
can
do
a
binary
search
for
us
to
find
the
right
commit
that
fixed,
it
cool
sure.
So,
you're.
B
A
Git,
wouldn't
get
wouldn't
sort
of
be
would
be
biased
that
way.
So,
let's
give
it
a
go,
so
we
start
with
get
bisect
start,
and
then
we
tell
it
what
the
that
this
is
this
commit
we're
on
right
now,
which
is
master,
is
good,
because
let
me
just
verify
we're
on
origin
master.
Yes,
so
get
bisect
good.
Is
this
one
so
get
bisect
view
just
to
see
where
we
are
so
we've
told
it
what
one
good
one
is.
B
A
Right,
if
I
do
get
bicep
start
get
bisect,
are
you
saying
good
and
old,
bad
and
new,
so
get
by
sex?
This
is
the
new
one.
Yeah
that
probably
makes
a
lot
more
sense.
Bisect
old
is,
let
me
just
verify
what
master
at
two
days
ago
was
it's
actually
coming
out
eight
days
ago,
which
is
probably
too
old?
Actually,
so
I
probably
want
to
be
more
specific
when
I
pick
out
that
commit,
let's
say.
B
A
A
A
A
A
B
Yeah,
so,
while
this
is
running,
let
me
ask
you
unrelated
questions
but
related
to
migrating
databases
and
booting
them
up.
Have
you
run
into
the
issue
of
oh,
it
looks
like
it's
good
to
go.
Have
you
run
into
the
issue
of
reviewing
emerge,
requests,
checking
out
a
branch,
running
migrations
and
there's
a
migration
on
that
branch,
but
then,
like
something
happens,
and
now
your
whole
local
database
is
broken
because
there's
a
migration
that
wasn't
is
not
a
master.
That's
in
your
local
database.
B
B
Just
just
the
technique,
I
know
so
I
don't
know
that's
that.
That's
burned
me
a
bunch
of
times,
though,
where
I'm
like
okay,
I
guess
I'm
restarting
everything,
because
our
our
guide
technically
says
like
hey.
If
you've
checked
out
something
with
the
migration
make
sure
you,
you
revert
the
migration
before
like
switching
branches
again
or
something,
but
I
don't
do
it
enough,
and
I
forget
about
it
every
time.
B
A
B
B
A
B
B
A
B
A
A
It's
not
working,
so
that's
good!
Yes,
that
means
that
I
we
correctly
chose
the
old
commit.
So
I'm
going
to
share
my
terminal
go
back
here
and
I
can
say
git
bisect
and
we
use
the
old
and
new
terminology,
and
I
guess
that's
saying
the
old
behavior
and
the
new
behavior,
so
this
is
still
showing
the
old
behavior
of
this
commit.
A
A
B
A
B
E
A
Personally,
I
wouldn't
use
it.
I
use
a
sort
of
I
use
keepassxc,
which
is
like
a
you
know.
Not
internet
connected
you've
just
got
an
application
which
processes
a
file
on
your
machine
and
it's
completely
local
and
that's
what
I
rely
on
personally,
but
I'm
pretty
it's
conservative
when
it
comes
to
stuff
like
that
and
yeah
it's
a
pain,
for
instance.
If
I
want
to
get
my
passwords,
but
I'm
in
another
country,
or
something
like
that,
I
can't
just
log
into
one
password.
B
B
A
I
do
genuinely
worry
about
my
google
account
getting
locked
or
hacked
or
whatever,
because
yeah
that's
a
everything
falls
like
dominoes
from
there.
It's
really
frightening
and
it
used
to
it
used
to
happen
years
ago.
People
would
find
that
their
google
accounts
their
goo.
Their
gmail
accounts
just
got
deleted
because
you
know
it
happens.
Hopefully
that
isn't
possible
anymore,
but
it
still
makes
me
worry
yeah.
Were
you
able
to
verify
master
that
commit
it's?
It's
still
booting
up
for
me.
It's
all
right.
A
A
B
A
A
A
B
B
B
A
B
I
will,
I
think
mine
finished
booting
up,
so
I'm
going
to
double
check
that
it's
well.
I
guess
I
don't
have
to
double
check.
Let's
fix
my
master.
We
just
checked
that
one
of
these
commits
is
fixed,
so
I'll
just
check
out
this
commit
and
double
check
it.
If
you
want
to
go
ahead
and
do
the
next
bicycle,
sir.
B
B
Oh,
you
know
you
read,
you
read
comments
about
like
there's
a
there's,
a
thread
on
hacker
news
saying
you
know
hey,
what's
what's
your
what's
the
worst
technology
that
you
have
to
use
every
day
and
someone
talks
about
get
like
not
being
intuitive
or
whatever,
and
I'm
like
it's,
it's
really
nice.
I
I've
used
like
team
foundation
server
like
when
I
was
doing
dot-net
stuff
and
I
just
wanted
to
jump
out
a
window
and
I
like.
A
Yeah,
I
think
the
git
cli
is
got
a
lot
of
rough
edges
like
a
thing
that
came
up
recently.
Is
the
discussion
of
how
the
git
cli
sort
of
confuses
the
concepts
of
squashing
and
re-basing,
but
they're
really,
you
know,
because
you
can
only
squash
while
re-basing,
but
technically
you
can
squash
without
rebasing,
and
you
can
rebase
without
squashing,
so
they're
kind
of
distinct
concepts,
and
things
like
that
like
if
you
want
to
set
the
branch
pointer
to
point
to
a
new
commit.
B
B
Yes,
that
should
be
a
slogan.
That's
super
helpful
once
you
get
what's
going
on,
but
I
think
yeah,
it's
it's
a
hard
problem
that
they're
solving
and
some
other
like
source
control
management,
stuff
that
like
deal
with
oh
well,
we
have
all
have
to
have
a
shared
file
system
that
we're
all
writing
on.
Like
those
kind
of
things
are
really
scary,
and
I
really
appreciate
the
problem
that
gets
solving
is
how
do
we
do
this
in
a
distributed
non-centralized
way,
and
I
can
appreciate
that
it's
it's
hard
I've.
Never!
B
When
I've
learned
new
git
commands,
I
don't
ever
really
like.
I
don't
find
myself
critiquing
it
for
its
lack
of
intuition.
I
just
I
guess.
A
lot
of
a
lot
of
the
terminal
stuff
seems
to
be
like
we're
so
far
removed
from
intuitive,
like
let's
just
appreciate
that
we're
we're
just
trying
to
piece
together
different
softwares.
As
best
we
can.
Oh.
A
B
A
While
we're
talking
about
git
and
version
control,
there's
a
an
experimental
version,
control
system
called
pigel,
which
is
super
interesting,
basically
git,
it's
possible
for
git
git's
merging
model
is
not
completely
sound,
as
in
you
can
get
the
wrong
behavior.
You
can
get
the
wrong
merge
result
given
to
two
branches
and
pigeon
goes
into
into
y
and
pigeon
fixes
that
and
pigel.
A
B
B
A
A
A
A
A
B
E
D
A
A
B
So
I
was
using
elementary
and
was
a
huge
fan
of
it,
and
then
I
was
doing
a
game
jam
and
was
going
to
be
using.
We
were
using
unity
and
unity
was
claiming
to
have
linux
support,
but
in
elementary
the
ui
was
just
super
wacky,
where
like
windows
had
no
scroll
bars,
but
they
were
overflowed.
You
had
to
like
drag
to
like
see
full
dialogues
of
like
wizards,
and
I
was
like
man.
B
B
Just
don't
okay,
I
kind
of
don't
like
the
snap
packages
thing
that
agreed
really
pushing,
and
that's
that's,
but
I
know
ubuntu
was
like
that's
the
target
distribution
whenever
there's
an
application,
it's
like
it's,
it
supports
linux.
They're
talking
it
works
on
ubuntu
or
do
you
feel
like
debian
is?
Is.
A
A
B
That's
what
really
scares
me
too
about
the
pine
phone,
my
my
dad
he's
getting
into
hacking
with
the
pine
phone.
He
wants
to
make
it
his
main
phone
and
stuff,
and
I'm
like
this
stuff
is
really
early,
which
means
you
know
we
haven't
found
all
the
bugs
yet,
and
that
kind
of
thing
is
really
scary,
something
I
tested
out.
D
E
A
E
A
You
do
this,
so
you
tell
if
bisect
starts,
so
it
knows
that
you're,
just
asking
bisector,
you
tell
it
that
the
current
commit
is
bad
or
you
that's.
An
alias
for
new
new
in
this
case
is
a
bit
clearer
because
it's
actually,
we
want
to
swap
the
bad
and
good
so
we'd
say,
get
bisect
new
on
master
and
then
get
bisect,
bad
or
old,
on
a
commit
that
you
knew
where
the
behavior
changed
and
then
that
kicks
off
doing
these
three
commands
then
kicks
off
a
process
where
it
gets
chooses.
E
A
B
A
What's
another
thing:
that's
pretty
cool
about
get
bisect.
Is
that
if
you
have
say
a
test
suite
that
you
can
run
via
a
script,
you
can
provide
that
script
to
get
bisect
and
it
will
just
check
out
each
commit
run
that
script
and
then
automatically
just
find
the
commit
for
you.
So
you
can
just
set
that
running
and
disappear
off
somewhere.
Unfortunately,
we
don't
have
that
yeah.
E
It's
the
yes,
the
comment
box.
The
rich
contentator
is
called
like
that
as
a
component,
I
don't
know
so
because,
right
before
the
last
commit
that
you
did,
I
was
checking
like
by
like
front-end
work,
and
there
is
a
editor
like
custom
render
identifier
for
like
we.
We
are
touching
the
rich
continental
review,
shared.
A
E
A
A
A
A
B
B
A
Yeah
this
is
this.
This
is
like
a
perfect
use
case
for
git
bisect
in
that
case,
because
it
could.
This
is
this.
Is
the
thing
like
with
keyboard
shortcuts,
sorry
keyboard
interactions
on
the
dom
like
anything
could
be?
You
could
have
completely
unrelated
component,
which
is
messing
this
up
right,
yeah.
E
A
B
B
E
B
E
B
B
A
I
used
to
use
mercurial
at
one
of
my
previous
companies
and
actually
the
you
know
how
you
specify
commit
ranges
and
stuff
in
git
the
way
mercurial
did
it.
It
had
its
own
like
language
for
that,
and
it
was
amazing
you
could
construct
super
like
complex
queries
to
get
exactly
the
commits
that
you
wanted,
and
I
missed
that
actually
wow.
B
A
There's
com:
this
is
again
where
git
is
weird,
though
so
that
feature
being
able
to
specify
a
date
stamp
in.
There
relies
on
your
ref
log,
not
on
the
commit
date,
which
means
that,
if
you've
cloned
the
repo
fresh,
I
don't
think
that
works.
If
you
see
what
I
mean,
because
your
ref
lock
is
empty,
which
is
rubbish
there,
we
are.
A
B
D
A
D
A
B
A
B
E
E
Again
because
I
added
a
point,
but
I
will
move
it
down
if
he's
at
the
meeting
so
that
we
can
first
get
to
east,
because
it's
like
what
it's
a
moment,
maybe
more
that
it's
going
through.
You
should
put
it
before
his
point,
just
yeah,
it's
already
before
his
point,
but
oh
really,
because
he
didn't
move
it.
So
that's
why
I
was
asking
you
if
he's
there.
Oh.
B
I'm
I'm
I'm
90
certain
he'll,
be
there
okay,
so
yeah
I
would
I
would
let's
do
his.
We
should
probably
do
his
point
first
because
that's
been,
unfortunately
bumped
a
couple
of
times.
I
think
this
next
week
we'll
do
the
apac
friendly
time,
and
so
I
need
to
figure
out
how
to
do
that
on
the
calendar.
So
I
think
every
week
we're
gonna
we're
gonna
do
alternating
aipac
and
emea,
america
time.
A
B
A
A
To
be
honest,
I
have
no
idea,
I
suspect,
not
like
rails
does
rails
is
so
dynamic.
It
just
probably
does
everything
all
the
time
does
all
the
things
all
the
time?
If
you
know
what
I
mean
unlike
python,
which
emits
bytecode
once
you've
run
it
once
kind
of
thing
and
updates
the
bytecode
afterwards,
but.
E
I
don't
know
I
was
coming
from
python
as
a
backhand
frame
framework
and
language
before
ruby,
and
I
must
say
that
I
appreciate
it
a
little
bit
more.
It's
officially
watch
python
and
jungle
in
general,
it's
also
more
of
like
newbie
friendly.
It's
friendlier.
Well,
python
is
known
to
be
like
very
simple
language,
right,
there's
less
magic
in
django
and
python.
Exactly
that's
the
thing.
The
least
magic
that
easier
is
to
control
click.
Your
life
around
right,
yeah,.
A
B
E
A
B
B
A
B
E
B
B
A
B
E
B
B
E
E
D
E
A
E
B
E
Yeah
no,
what
I
was
pointing
out
is
definitely
technically
wise.
It's
not
okay,
but
it
cause
attrition
with
the
altar,
especially
if
they
are
not
front-end,
but
it's
a
community
contribution.
Then
they
will
do
something
that
follows
the
dogs
and
then
you
go
something
like
no.
We
can't
do
this.
This
is
super
wrong
fix
this
and
they're
like
well.
I
was
following
the
dogs.
B
B
A
A
E
A
E
A
E
E
E
E
E
B
E
B
More
than
linear
yes,
no,
it's
definitely
it's
definitely
linear,
but
like
what
I'm-
and
this
is
an
edge
case,
but
since
we
don't
know
what's
causing
it,
here's
here's
an
edge.
If
if
we
had
fixed
it
and
broke
it
and
then
fixed
it,
and
then
we
tried
to
do
binary
search,
we
would
we
could
end
up
in
a
spot
that
doesn't
actually
help
us.
A
C
B
A
E
D
A
E
A
B
A
E
E
B
B
That's
that's
what
yeah
that's
one
thing
we
could
do
too
if
we
have
a
feature
spec
for
it,
but
we'd
have
to
also
like
run
we'd
have
to
create
a
script
that
also
like
refreshes,
the
gdk
and
stuff
and
runs
a
feature
spec
and
that's
totally
doable,
and
that
would
be
cool
yeah
if
we
write
a
feature
spec
for
it.
We
protect
ourselves
from
the
future
and
we're
able
to
determine
when
it
got
introduced.
E
B
B
E
A
Right,
so
what
I
was
doing,
yeah
was
in
in
a
in
a
reply
in
a
thread,
add
emojis
and
a
label
and
use
the
try
and
use
the
keyboard
as
well
yeah
yeah
yeah.
This
is,
I
didn't
click
anything
here
and
then
connect
that
and
then
at
the
bottom
in
there
yeah.
It
make
sure
that
try
this
now
does
the
keyboard
work.
This
works
yeah.
Can
you
refresh?
B
A
A
B
B
B
There
are
multiple
of
these
suggestion,
containers
I
get
created
and
it
seems
like
maybe
one
thing
that
can
happen
too.
I
need
to
try
to
recreate
this
on
master
yeah.
I'm
gonna
try
to
recreate
on
master.
I
was
able
to
do
this
consistently,
but
I
don't
know
if
this
is
the
same
bug
or
not,
can
you
can
you
go
ahead
and
share
your
screen
nico,
here's
something
I
was
able
to
do
almost
consider.
I.
E
B
E
B
You're
good,
I
might
be
able
to
do.
Let
me
share
my
screen
and
then,
let's
all
hop
off
in
a
little
bit.
This
has
been
a
freaking
helpful
session.
I
really
appreciate
us
going
through
this
and
talking
about
it,
it's
a
little
sad
that
we
haven't
fixed
it
or
know
anything
more
about
the
problem
at
all,
but
I
think
the
next.
B
E
A
But
I
think
that's
not
if,
if
we
basically
write
a
script
which
does
what
we
were
doing
already,
then
it's
still
going
to
have
this
flakiness
to
it,
where
sometimes
past
sometimes
fail.
So
it's
not
going
to
help
us
get
any
close
to
what
the
problem
is.
If
you
see
what
I
mean
I
do,
that
said,
we
could
run
the
pipeline
like
many
times
on
a
very
old,
commit
and
then
buy
sex
on
that.
So
you
basically
have
to
run
the
test
several
times
to
be
sure
or.
B
Yeah,
if
you're
really
serious
about
solving
this,
and
it's
going
to
be
some
work
but
you're
right.
I
think
looking
at
this
slice,
where
the
issue
is
like
prevalent,
but
now
it's
available,
its
visibility
is,
is
flaky,
that's
a
little
strange,
but
if
we
move
our
slice
to
like
two
weeks
ago,
when
this
wasn't
a
problem
to
three
days
ago,
when
this
was
very
prevalent,
I
think
we
would
see
what
maybe
caused
this
and
rather
than
looking
at
what
might
have
fixed
it.
That
might
reveal
something
interesting.
