Patrick Steinhardt [Thu, 16 Feb 2023 10:29:48 +0000 (11:29 +0100)] 
delta-islands: fix segfault when freeing island marks

In 647982bb71 (delta-islands: free island_marks and bitmaps, 2023-02-03)
we have introduced logic to free `island_marks` in order to reduce heap
memory usage in git-pack-objects(1). This commit is causing segfaults in
the case where this Git command does not load delta islands at all, e.g.
when reading object IDs from standard input. One such crash can be hit
when using repacking multi-pack-indices with delta islands enabled.

The root cause of this bug is that we unconditionally dereference the
`island_marks` variable even in the case where it is a `NULL` pointer,
which is fixed by making it conditional. Note that we still leave the
logic in place to set the pointer to `-1` to detect use-after-free bugs
even when there are no loaded island marks at all.

2 years agoadd basic http proxy tests
Jeff King [Thu, 16 Feb 2023 20:56:32 +0000 (15:56 -0500)] 
add basic http proxy tests

We do not test our http proxy functionality at all in the test suite, so
this is a pretty big blind spot. Let's at least add a basic check that
we can go through an authenticating proxy to perform a clone.

A few notes on the implementation:

  - I'm using a single apache instance to proxy to itself. This seems to
    work fine in practice, and we can check with a test that this rather
    unusual setup is doing what we expect.

  - I've put the proxy tests into their own script, and it's the only
    one which loads the apache proxy config. If any platform can't
    handle this (e.g., doesn't have the right modules), the start_httpd
    step should fail and gracefully skip the rest of the script (but all
    the other http tests in existing scripts will continue to run).

  - I used a separate passwd file to make sure we don't ever get
    confused between proxy and regular auth credentials. It's using the
    antiquated crypt() format. This is a terrible choice security-wise
    in the modern age, but it's what our existing passwd file uses, and
    should be portable. It would probably be reasonable to switch both
    of these to bcrypt, but we can do that in a separate patch.

  - On the client side, we test two situations with credentials: when
    they are present in the url, and when the username is present but we
    prompt for the password. I think we should be able to handle the
    case that _neither_ is present, but an HTTP 407 causes us to prompt
    for them. However, this doesn't seem to work. That's either a bug,
    or at the very least an opportunity for a feature, but I punted on
    it for now. The point of this patch is just getting basic coverage,
    and we can explore possible deficiencies later.

  - this doesn't work with LIB_HTTPD_SSL. This probably would be
    valuable to have, as https over an http proxy is totally different
    (it uses CONNECT to tunnel the session). But adding in
    mod_proxy_connect and some basic config didn't seem to work for me,
    so I punted for now. Much of the rest of the test suite does not
    currently work with LIB_HTTPD_SSL either, so we shouldn't be making
    anything much worse here.

rev-list: clarify git-log default date format

The documentation mistakenly said that the default format was
similar to RFC 2822 format and tried to specify it by enumerating
differences, which had two problems:

 * There are some more differences from the 2822 format that are not
   mentioned; worse yet

 * The default format is not modeled after RFC 2822 format at all.
   As can be seen in f80cd783 (date.c: add "show_date()" function.,
   2005-05-06), it is a derivative of ctime(3) format.

Stop saying that it is similar to RFC 2822, and rewrite the
description to explain the format without requiring the reader to
know any other format.

Elijah Newren [Thu, 9 Feb 2023 09:11:46 +0000 (09:11 +0000)] 
name-rev: fix names by dropping taggerdate workaround

Commit 7550424804 ("name-rev: include taggerdate in considering the best
name", 2016-04-22) introduced the idea of using taggerdate in the
criteria for selecting the best name.  At the time, a certain commit in
linux.git -- namely, aed06b9cfcab -- was being named by name-rev as
    v4.6-rc1~9^2~792
which, while correct, was very suboptimal.  Some investigation found
that tweaking the MERGE_TRAVERSAL_WEIGHT to lower it could give
alternate answers such as
    v3.13-rc7~9^2~14^2~42
or
    v3.13~5^2~4^2~2^2~1^2~42
A manual solution involving looking at tagger dates came up with
    v3.13-rc1~65^2^2~42
which is much nicer.  That workaround was then implemented in name-rev.

Unfortunately, the taggerdate heuristic is causing bugs.  I was pointed
to a case in a private repository where name-rev reports a name of the
form
    v2022.10.02~86
when users expected to see one of the form
    v2022.10.01~2
(I've modified the names and numbers a bit from the real testcase.)  As
you can probably guess, v2022.10.01 was created after v2022.10.02 (by a
few hours), even though it pointed to an older commit.  While the
condition is unusual even in the repository in question, it is not the
only problematic set of tags in that repository.  The taggerdate logic
is causing problems.

Further, it turns out that this taggerdate heuristic isn't even helping
anymore.  Due to the fix to naming logic in 3656f84278 ("name-rev:
prefer shorter names over following merges", 2021-12-04), we get
improved names without the taggerdate heuristic.  For the original
commit of interest in linux.git, a modern git without the taggerdate
heuristic still provides the same optimal answer of interest, namely:
    v3.13-rc1~65^2^2~42

So, the taggerdate is no longer providing benefit, and it is causing
problems.  Simply get rid of it.

However, note that "taggerdate" as a variable is used to store things
besides a taggerdate these days.  Ever since commit ef1e74065c
("name-rev: favor describing with tags and use committer date to
tiebreak", 2017-03-29), this has been used to store committer dates and
there it is used as a fallback tiebreaker (as opposed to a primary
criteria overriding effective distance calculations).  We do not want to
remove that fallback tiebreaker, so not all instances of "taggerdate"
are removed in this change.

The current set of regular expressions in userdiff.c already allows the

"non-sealed", which is the first hyphenated keyword in Java.[2]  Allow
hyphen in the words that precede the name of type to match the
"non-sealed" modifier.

In new input file "java-sealed" for the test t4018-diff-funcname.sh, use
