Junio C Hamano 2125261b63 Merge branch 'jk/split-broken-ident'
Make the fall-back parsing of commit objects with broken author or
committer lines more robust to pick up the timestamps.

* jk/split-broken-ident:
  split_ident: parse timestamp from end of line
2013-10-28 10:43:32 -07:00
Jeff King 03818a4a94 split_ident: parse timestamp from end of line
Split_ident currently parses left to right. Given this
input:

  Your Name <email@example.com> 123456789 -0500\n

We assume the name starts the line and runs until the first
"<".  That starts the email address, which runs until the
first ">".  Everything after that is assumed to be the
timestamp.

This works fine in the normal case, but is easily broken by
corrupted ident lines that contain an extra ">". Some
examples seen in the wild are:

  1. Name <email>-<> 123456789 -0500\n

  2. Name <email> <Name<email>> 123456789 -0500\n

  3. Name1 <email1>, Name2 <email2> 123456789 -0500\n

Currently each of these produces some email address (which
is not necessarily the one the user intended) and end up
with a NULL date (which is generally interpreted as the
epoch by "git log" and friends).

But in each case we could get the correct timestamp simply
by parsing from the right-hand side, looking backwards for
the final ">", and then reading the timestamp from there.

In general, it's a losing battle to try to automatically
guess what the user meant with their broken crud. But this
particular workaround is probably worth doing.  One, it's
dirt simple, and can't impact non-broken cases. Two, it
doesn't catch a single breakage we've seen, but rather a
large class of errors (i.e., any breakage inside the email
angle brackets may affect the email, but won't spill over
into the timestamp parsing). And three, the timestamp is
arguably more valuable to get right, because it can affect
correctness (e.g., in --until cutoffs).

This patch implements the right-to-left scheme described
above. We adjust the tests in t4212, which generate a commit
with such a broken ident, and now gets the timestamp right.
We also add a test that fsck continues to detect the
breakage.

For reference, here are pointers to the breakages seen (as
numbered above):

Jeff King 662cc30cd0 format-patch: print in-body "From" only when needed
Commit a908047 taught format-patch the "--from" option,
which places the author ident into an in-body from header,
and uses the committer ident in the rfc822 from header.  The
documentation claims that it will omit the in-body header
when it is the same as the rfc822 header, but the code never
implemented that behavior.

This patch completes the feature by comparing the two idents
and doing nothing when they are the same (this is the same
as simply omitting the in-body header, as the two are by
definition indistinguishable in this case). This makes it
reasonable to turn on "--from" all the time (if it matches
your particular workflow), rather than only using it when
exporting other people's patches.

An earlier conversion from fgets() to strbuf_getline() in the
codepath to read from /etc/mailname to learn the default host-part
of the ident e-mail address forgot that strbuf_getline() stores the
line at the beginning of the buffer just like fgets().

The "username@" the caller has prepared in the strbuf, expecting the
function to append the host-part to it, was lost because of this.

Jeff King d6991ceedc ident: keep separate "explicit" flags for author and committer
We keep track of whether the user ident was given to us
explicitly, or if we guessed at it from system parameters
like username and hostname. However, we kept only a single
variable. This covers the common cases (because the author
and committer will usually come from the same explicit
source), but can miss two cases:

  1. GIT_COMMITTER_* is set explicitly, but we fallback for
     GIT_AUTHOR. We claim the ident is explicit, even though
     the author is not.

  2. GIT_AUTHOR_* is set and we ask for author ident, but
     not committer ident. We will claim the ident is
     implicit, even though it is explicit.

This patch uses two variables instead of one, updates both
when we set the "fallback" values, and updates them
individually when we read from the environment.

Rather than keep user_ident_sufficiently_given as a
compatibility wrapper, we update the only two callers to
check the committer_ident, which matches their intent and
what was happening already.

In v1.5.6-rc0~56^2 (2008-05-04) "user_ident_explicitly_given"

Jeff King f9bc573fda ident: rename IDENT_ERROR_ON_NO_NAME to IDENT_STRICT
Callers who ask for ERROR_ON_NO_NAME are not so much
concerned that the name will be blank (because, after all,
we will fall back to using the username), but rather it is a
check to make sure that low-quality identities do not end up
in things like commit messages or emails (whereas it is OK
for them to end up in things like reflogs).

When future commits add more quality checks on the identity,
each of these callers would want to use those checks, too.
Rather than modify each of them later to add a new flag,
let's refactor the flag.

Jeff King c15e1987ae ident: let callers omit name with fmt_indent
Most callers want to see all of "$name <$email> $date", but
a few want only limited parts, omitting the date, or even
the name. We already have IDENT_NO_DATE to handle the date
part, but there's not a good option for getting just the
email. Callers have to done one of:

  1. Call ident_default_email; this does not respect
     environment variables, nor does it promise to trim
     whitespace or other crud from the result.

  2. Call git_{committer,author}_info; this returns the name
     and email, leaving the caller to parse out the wanted
     bits.

This patch adds IDENT_NO_NAME; it stops short of adding
IDENT_NO_EMAIL, as no callers want it (nor are likely to),
and it complicates the error handling of the function.

When no name is requested, the angle brackets (<>) around
the email address are also omitted.

As a short-hand, we extract this flag into the local
variable "name_addr_only". It's more accurate to simply
negate this and refer to it as "want_date", which will be
less confusing when we add more NO_* flags.

While we're touching this part of the code, let's move the
call to ident_default_date() only when we are actually going
to use it, not when we have NO_DATE set, or when we get a
date from the environment.

Jeff King be641abdb5 ident: trim whitespace from default name/email
Usually these values get fed to fmt_ident, which will trim
any cruft anyway, but there are a few code paths which use
them directly. Let's clean them up for the benefit of those
callers. Furthermore, fmt_ident will look at the pre-trimmed
value and decide whether to invoke ERROR_ON_NO_NAME; this
check can be fooled by a name consisting only of spaces.

Note that we only bother to clean up when we are pulling the
information from gecos or from system files. Any other value
comes from a config file, where we will have cleaned up
accidental whitespace already.

Jeff King f8254d321c ident: use full dns names to generate email addresses
When we construct an email address from the username and
hostname, we generate the host part of the email with this
procedure:

  1. add the result of gethostname

  2. if it has a dot, ok, it's fully qualified

  3. if not, then look up the unqualified hostname via
     gethostbyname; take the domain name of the result and
     append it to the hostname

Step 3 can actually produce a bogus result, as the name
returned by gethostbyname may not be related to the hostname
we fed it (e.g., consider a machine "foo" with names
"foo.one.example.com" and "bar.two.example.com"; we may have
the latter returned and generate the bogus name
"foo.two.example.com").

This patch simply uses the full hostname returned by
gethostbyname. In the common case that the first part is the
same as the unqualified hostname, the behavior is identical.
And in the case that it is not the same, we are much more
likely to be generating a valid name.

Jeff King 2f70587502 ident: report passwd errors with a more friendly message
When getpwuid fails, we give a cute but cryptic message.
While it makes sense if you know that getpwuid or identity
functions are being called, this code is triggered behind
the scenes by quite a few git commands these days (e.g.,
receive-pack on a remote server might use it for a reflog;
the current message is hard to distinguish from an
authentication error).  Let's switch to something that gives
a little more context.

While we're at it, we can factor out all of the
cut-and-pastes of the "you don't exist" message into a
wrapper function. Rather than provide xgetpwuid, let's make
it even more specific to just getting the passwd entry for
the current uid. That's the only way we use getpwuid anyway,
and it lets us make an even more specific error message.

The current message also fails to mention errno. While the
usual cause for getpwuid failing is that the user does not
exist, mentioning errno makes it easier to diagnose these
problems.  Note that POSIX specifies that errno remain
untouched if the passwd entry does not exist (but will be
set on actual errors), whereas some systems will return
ENOENT or similar for a missing entry. We handle both cases
in our wrapper.

Jeff King 8587ead78a drop length limitations on gecos-derived names and emails
When we pull the user's name from the GECOS field of the
passwd file (or generate an email address based on their
username and hostname), we put the result into a
static buffer. While it's extremely unlikely that anybody
ever hit these limits (after all, in such a case their
parents must have hated them), we still had to deal with the
error cases in our code.

Converting these static buffers to strbufs lets us simplify
the code and drop some error messages from the documentation
that have confused some users.

The conversion is mostly mechanical: replace string copies
with strbuf equivalents, and access the strbuf.buf directly.
There are a few exceptions:

  - copy_gecos and copy_email are the big winners in code
    reduction (since they no longer have to manage the
    string length manually)

  - git_ident_config wants to replace old versions of
    the default name (e.g., if we read the config multiple
    times), so it must reset+add to the strbuf instead of
    just adding

Note that there is still one length limitation: the
gethostname interface requires us to provide a static
buffer, so we arbitrarily choose 1024 bytes for the
hostname.

Jeff King 060d4bb3d6 ident: don't write fallback username into git_default_name
The fmt_ident function gets a flag that tells us whether to
die if the name field is blank. If it is blank and we don't
die, then we fall back to the username from the passwd file.

The current code writes the value into git_default_name.
However, that's not necessarily correct, as the empty value
might have come from git_default_name, or it might have been
passed in.  This leads to two potential problems:

  1. If we are overriding an empty name in the passed-in
     value, then we may be overwriting a perfectly good name
     (from gitconfig or gecos) in the git_default_name
     buffer. Later calls to fmt_ident will end up using the
     fallback name, even though a better name was available.

  2. If we override an empty gecos name, we end up with the
     fallback name in git_default_name. A later call that
     uses IDENT_ERROR_ON_NO_NAME will see the fallback name
     and think that it is a good name, instead of producing
     an error. In other words, a blank gecos name would
     cause an error with this code:

       git_committer_info(IDENT_ERROR_ON_NO_NAME);

     but not this:

       git_committer_info(0);
       git_committer_info(IDENT_ERROR_ON_NO_NAME);

     because in the latter case, the first call has polluted
     the name buffer.

Instead, let's make the fallback a per-invocation variable.
We can just use the pw->pw_name string directly, since it
only needs to persist through the rest of the function (and
we don't do any other getpwent calls).

Note that while this solves (1) for future invocations of
fmt_indent, the current invocation might use the fallback
when it could in theory load a better value from
git_default_name. However, by not passing
IDENT_ERROR_ON_NO_NAME, the caller is indicating that it
does not care too much about the name, anyway, so we don't
bother; this is primarily about protecting future callers
who do care.

Jonathan Nieder d855e4d35d ident: do not retrieve default ident when unnecessary
Avoid a getpwuid() call (which contacts the network if the password
database is not local), read of /etc/mailname, gethostname() call, and
reverse DNS lookup if the user has already chosen a name and email
through configuration, the environment, or the command line.

This should slightly speed up commands like "git commit".  More
importantly, it improves error reporting when computation of the
default ident string does not go smoothly.  For example, after
detecting a problem (e.g., "warning: cannot open /etc/mailname:
Permission denied") in retrieving the default committer identity:

	touch /etc/mailname;	# as root
	chmod -r /etc/mailname;	# as root
	git commit -m 'test commit'

you can squelch the warning while waiting for your sysadmin to fix the
permissions problem.

	echo '[user] email = me@example.com' >>~/.gitconfig

Jonathan Nieder 8a55caa8a3 ident: check /etc/mailname if email is unknown
Before falling back to gethostname(), check /etc/mailname if
GIT_AUTHOR_EMAIL is not set in the environment or through config
files.  Only fall back if /etc/mailname cannot be opened or read.

The /etc/mailname convention comes from Debian policy section 11.6
("mail transport, delivery and user agents"), though maybe it could be
useful sometimes on other machines, too.  The lack of this support was
noticed by various people in different ways:

 - Ian observed that git was choosing the address
   'ian@anarres.relativity.greenend.org.uk' rather than
   'ian@davenant.greenend.org.uk' as it should have done.

 - Jonathan noticed that operations like "git commit" were needlessly
   slow when using a resolver that was slow to handle reverse DNS
   lookups.

Alas, after this patch, if /etc/mailname is set up and the [user] name
and email configuration aren't, the committer email will not provide a
charming reminder of which machine commits were made on any more.  But
I think it's worth it.

Mechanics: the functionality of reading mailname goes in its own
function, so people who care about other distros can easily add an
implementation to a similar location without making copy_email() too
long and losing clarity.  While at it, we split out the fallback
default logic that does gethostname(), too (rearranging it a little
and adding a check for errors from gethostname while at it).

Based on a patch by Gerrit Pape <pape@smarden.org>.

Jeff King 4579bb418c ident: die on bogus date format
If the user gives "git commit --date=foobar", we silently
ignore the --date flag. We should note the error.

This patch puts the fix at the lowest level of fmt_ident,
which means it also handles GIT_AUTHOR_DATE=foobar, as well.

There are two down-sides to this approach:

  1. Technically this breaks somebody doing something like
     "git commit --date=now", which happened to work because
     bogus data is the same as "now". Though we do
     explicitly handle the empty string, so anybody passing
     an empty variable through the environment will still
     work.

     If the error is too much, perhaps it can be downgraded
     to a warning?

  2. The error checking happens _after_ the commit message
     is written, which can be annoying to the user. We can
     put explicit checks closer to the beginning of
     git-commit, but that feels a little hack-ish; suddenly
     git-commit has to care about how fmt_ident works. Maybe
     we could simply call fmt_ident earlier?

bb1ae3f (commit: Show committer if automatic, 2008-05-04) added a logic to
check both name and email were given explicitly by the end user, but it
assumed that fmt_ident() is never called before git_default_user_config()
is called, which was fragile.  The former calls setup_ident() and fills
the "default" name and email, so the check in the config parser would have
mistakenly said both are given even if only user.name was provided.

Make the logic more robust by keeping track of name and email separately.

Linus Torvalds d404bf0288 Add backslash to list of 'crud' characters in real name
We remove crud characters at the beginning and end of real-names so that
when we see email addresses like

	From: "David S. Miller" <davem@davemloft.net>

we drop the quotes around the name when we parse that and split it up into
name and email.

However, the list of crud characters was basically just a random list of
common things that are found around names, and it didn't contain the
backslash character that some insane scripts seem to use when quoting
things. So now the kernel has a number of authors listed like

	Author: \"Rafael J. Wysocki\ <rjw@sisk.pl>

because the author name had started out as

	From: \"Rafael J. Wysocki\" <rjw@sisk.pl>

and the only "crud" character we noticed and removed was the final
double-quote at the end.

We should probably do better quote removal from names anyway, but this is
the minimal obvious patch.

Junio C Hamano 774751a8bc Re-fix "builtin-commit: fix --signoff"
An earlier fix to the said commit was incomplete; it mixed up the
meaning of the flag parameter passed to the internal fmt_ident()
function, so this corrects it.

git_author_info() and git_committer_info() can be told to issue a
warning when no usable user information is found, and optionally can be
told to error out.  Operations that actually use the information to
record a new commit or a tag will still error out, but the caller to
leave reflog record will just silently use bogus user information.

Not warning on misconfigured user information while writing a reflog
entry is somewhat debatable, but it is probably nicer to the users to
silently let it pass, because the only information you are losing is who
checked out the branch.

 * git_author_info() and git_committer_info() used to take 1 (positive
   int) to error out with a warning on misconfiguration; this is now
   signalled with a symbolic constant IDENT_ERROR_ON_NO_NAME.

 * These functions used to take -1 (negative int) to warn but continue;
   this is now signalled with a symbolic constant IDENT_WARN_ON_NO_NAME.

 * fmt_ident() function implements the above error reporting behaviour
   common to git_author_info() and git_committer_info().  A symbolic
   constant IDENT_NO_DATE can be or'ed in to the flag parameter to make
   it return only the "Name <email@address.xz>".

 * fmt_name() is a thin wrapper around fmt_ident() that always passes
   IDENT_ERROR_ON_NO_NAME and IDENT_NO_DATE.

Junio C Hamano cb280e1075 Allow non-developer to clone, checkout and fetch more easily.
The code that uses committer_info() in reflog can barf and die
whenever it is asked to update a ref.  And I do not think
calling ignore_missing_committer_name() upfront like recent
receive-pack did in the aplication is a reasonable workaround.

What the patch does.

 - git_committer_info() takes one parameter.  It used to be "if
   this is true, then die() if the name is not available due to
   bad GECOS, otherwise issue a warning once but leave the name
   empty".  The reason was because we wanted to prevent bad
   commits from being made by git-commit-tree (and its
   callers).  The value 0 is only used by "git var -l".

   Now it takes -1, 0 or 1.  When set to -1, it does not
   complain but uses the pw->pw_name when name is not
   available.  Existing 0 and 1 values mean the same thing as
   they used to mean before.  0 means issue warnings and leave
   it empty, 1 means barf and die.

 - ignore_missing_committer_name() and its existing caller
   (receive-pack, to set the reflog) have been removed.

 - git-format-patch, to come up with the phoney message ID when
   asked to thread, now passes -1 to git_committer_info().  This
   codepath uses only the e-mail part, ignoring the name.  It
   used to barf and die.  The other call in the same program
   when asked to add signed-off-by line based on committer
   identity still passes 1 to make sure it barfs instead of
   adding a bogus s-o-b line.

 - log_ref_write in refs.c, to come up with the name to record
   who initiated the ref update in the reflog, passes -1.  It
   used to barf and die.

The last change means that git-update-ref, git-branch, and
commit walker backends can now be used in a repository with
reflog by somebody who does not have the user identity required
to make a commit.  They all used to barf and die.

I've run tests and all of them seem to pass, and also tried "git
clone" as a user whose GECOS is empty -- git clone works again
now (it was broken when reflog was enabled by default).

But this definitely needs extra sets of eyeballs.

If GIT_COMMITTER_NAME is not available in receive-pack but reflogs

Now that reflogs are enabled by default in (what we guessed to be)

who don't have their full name in the gecos field and who don't
have access to the remote system to correct the problem.

domain name (it seems to be mostly some scary NIS/YP thing).

This patch changes the code to actually use the DNS domain name, which is
also what tends to be used in emails, and we aim at emails with our ident
code.

Linus Torvalds 4546738b58 Unlocalized isspace and friends
Do our own ctype.h, just to get the sane semantics: we want
locale-independence, _and_ we want the right signed behaviour. Plus we
only use a very small subset of ctype.h anyway (isspace, isalpha,
isdigit and isalnum).

Linus Torvalds e1b10391ea Use git config file for committer name and email info
This starts using the "user.name" and "user.email" config variables if
they exist as the default name and email when committing.  This means
that you don't have to use the GIT_COMMITTER_EMAIL environment variable
to override your email - you can just edit the config file instead.

The patch looks bigger than it is because it makes the default name and
email information non-static and renames it appropriately.  And it moves
the common git environment variables into a new library file, so that
you can link against libgit.a and get the git environment without having
to link in zlib and libcrypt.

In short, most of it is renaming and moving, the real change core is
just a few new lines in "git_default_config()" that copies the user
config values to the new base.

It also changes "git-var -l" to list the config variables.

Junio C Hamano e9bacb4f6a Use GECOS field a bit better to produce default human readable name.
This updates the default human readable name we generate from GECOS
field.  We assume the "full-name, followed by additional information
separated by commas" format, with an & expanding to the capitalized
login name.

Patrick Mauritz f0ebff0dfe [PATCH] Portability fix for Solaris 10/x86
* getdomainname unavailable there.
 * needs -lsocket for linkage.
 * needs __EXTENSIONS__ at the beginning of convert-objects.c

[JC: I've done this slightly differently from what Patrick originally
sent to the list and dropped the bit that deals with installations
that has curl header and library at non-default location.  I am
resisting the slipperly slope called autoconf.]
