2017-03-24t7004, t7030: fix here-doc syntax errorsSantiago Torres2-14/+10
Jan Palus noticed that some here-doc are spelled incorrectly, resulting the entire remainder of the test snippet being slurped into the "expect" file as if it were data, e.g. in this sequence cat >expect <<EOF && ... expectation ... EOF git $cmd_being_tested >actual && test_cmp expect actual the last command of the test is "cat" that sends everything to 'expect' and succeeds. Fixing these issues in t7004 and t7030 reveals that "git tag -v" and "git verify-tag" with their --format option do not work as the test was expecting originally. Instead of showing both valid tags and tags with incorrect signatures on their output, tags that do not pass verification are omitted from the output. Another breakage that is uncovered is that these tests must be restricted to environment where gpg is available. Arguably, that is a safer behaviour, and because the format specifiers like %(tag) do not have a way to show if the signature verifies correctly, the command with the --format option cannot be used to get a list of tags annotated with their signature validity anyway. For now, let's fix the here-doc syntax, update the expectation to match the reality, and update the test prerequisite. Maybe later when we extend the --format language available to "git tag -v" and "git verify-tag" to include things like "%(gpg:status)", we may want to change the behaviour so that piping a list of tag names into xargs git verify-tag --format='%(gpg:status) %(tag)' becomes a good way to produce such a list, but that is a separate topic.

2017-03-20push: mention "push.default=tracking" in the documentationÆvar Arnfjörð Bjarmason1-0/+2
Change the documentation for push.tracking=* to re-include a mention of what "tracking" does. The "tracking" option was renamed to "upstream" back in 53c4031 ("push.default: Rename 'tracking' to 'upstream'", 2011-02-16), this section was then subsequently rewritten in 87a70e4 ("config doc: rewrite push.default section", 2013-06-19) to remove any mention of "tracking". Maybe we should just warn or die nowadays if this option is in the config, but I had some old config of mine use this option, I'd forgotten that it was a synonym, and nothing in git's documentation mentioned that. That's bad, either we shouldn't support it at all, or we should document what it does. This patch does the latter.

2017-03-18pickaxe: fix segfault with '-S<...> --pickaxe-regex'SZEDER Gábor2-2/+10
'git {log,diff,...} -S<...> --pickaxe-regex' can segfault as a result of out-of-bounds memory reads. diffcore-pickaxe.c:contains() looks for all matches of the given regex in a buffer in a loop, advancing the buffer pointer to the end of the last match in each iteration. When we switched to REG_STARTEND in b7d36ffca (regex: use regexec_buf(), 2016-09-21), we started passing the size of that buffer to the regexp engine, too. Unfortunately, this buffer size is never updated on subsequent iterations, and as the buffer pointer advances on each iteration, this "bufptr+bufsize" points past the end of the buffer. This results in segmentation fault, if that memory can't be accessed. In case of 'git log' it can also result in erroneously listed commits, if the memory past the end of buffer is accessible and happens to contain data matching the regex. Reduce the buffer size on each iteration as the buffer pointer is advanced, thus maintaining the correct end of buffer location. Furthermore, make sure that the buffer pointer is not dereferenced in the control flow statements when we already reached the end of the buffer. The new test is flaky, I've never seen it fail on my Linux box even without the fix, but this is expected according to db5dfa3 (regex: -G<pattern> feeds a non NUL-terminated string to regexec() and fails, 2016-09-21). However, it did fail on Travis CI with the first (and incomplete) version of the fix, and based on that commit message I would expect the new test without the fix to fail most of the time on Windows.

2017-03-18run-command: fix segfault when cleaning forked async processJeff King1-1/+1
Callers of the run-command API may mark a child as "clean_on_exit"; it gets added to a list and killed when the main process dies. Since commit 46df6906f (execv_dashed_external: wait for child on signal death, 2017-01-06), we respect an extra "wait_after_clean" flag, which we expect to find in the child_process struct. When Git is built with NO_PTHREADS, we start "struct async" processes by forking rather than spawning a thread. The resulting processes get added to the cleanup list but they don't have a child_process struct, and the cleanup function ends up dereferencing NULL. We should notice this case and assume that the processes do not need to be waited for (i.e., the same behavior they had before 46df6906f).

2017-03-18tests: make the 'test_pause' helper work in non-verbose modeSZEDER Gábor1-7/+2
When the 'test_pause' helper function invokes the shell mid-test, it explicitly redirects the shell's stdout and stderr to file descriptors 3 and 4, which are the stdout and stderr of the tests (i.e. where they would be connected anyway without those redirections). These file descriptors are only attached to the terminal in verbose mode, hence the restriction of 'test_pause' to work only with '-v'. Redirect the shell's stdout and stderr to the test environment's original stdout and stderr, allowing it to work properly even in non-verbose mode, and the restriction can be lifted.

2017-03-18tests: create an interactive gdb session with the 'debug' helperSZEDER Gábor2-1/+2
The 'debug' test helper is supposed to facilitate debugging by running a command of the test suite under gdb. Unfortunately, its usefulness is severely limited, because that gdb session is not interactive, since the test's, and thus gdb's standard input is redirected from /dev/null (for a good reason, see 781f76b15 (test-lib: redirect stdin of tests, 2011-12-15)). Redirect gdb's standard file descriptors from/to the test environment's stdin, stdout and stderr in the 'debug' helper, thus creating an interactive gdb session (even in non-verbose mode), which is much, much more useful.

There are two subtleties to note: - the original called for_each_branch_ref(), etc, in the non-glob case. Now we will call for_each_ref_in("refs/heads/") which is exactly what for_each_branch_ref() did under the hood. - for --glob, we'll call for_each_glob_ref_in() with a NULL "prefix" argument. Which is exactly what for_each_glob_ref() was doing already. So both cases should behave identically, and it seems reasonable to assume that this will remain the same. The functions we are calling now are the more-generic ones, and the ones we are dropping are just convenience wrappers.

2017-03-15rev-parse: add helper for parsing "--foo/--foo="Jeff King1-10/+28
We can't just use a bare skip_prefix() for these cases, because we need to match both the "--foo" form and the "--foo=<value>" form (and tell the difference between the two in the caller). We can wrap this in a simple helper which has two obvious callsites, and will gain some more in the next patch. Note that the error output for abbrev-ref changes slightly, as we don't keep our original "arg" pointer. However, the new output should hopefully be more clear: [before] fatal: unknown mode for --abbrev-ref=foo [after] fatal: unknown mode for --abbrev-ref: foo Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Make sure that the remaining two strings (initial commit, detached head) are stable, too. These changes are for the v1 porcelain interface.

2017-03-13http-walker: fix buffer underflow processing remote alternatesJeff King1-4/+7
If we parse a remote alternates (or http-alternates), we expect relative lines like: ../../foo.git/objects which we convert into "$URL/../foo.git/" (and then use that as a base for fetching more objects). But if the remote feeds us nonsense like just: ../ we will try to blindly strip the last 7 characters, assuming they contain the string "objects". Since we don't _have_ 7 characters at all, this results in feeding a small negative value to strbuf_add(), which converts it to a size_t, resulting in a big positive value. This should consistently fail (since we can't generall allocate the max size_t minus 7 bytes), so there shouldn't be any security implications. Let's fix this by using strbuf_strip_suffix() to drop the characters we want. If they're not present, we'll ignore the alternate (in theory we could use it as-is, but the rest of the http-walker code unconditionally tacks "objects/" back on, so it is it not prepared to handle such a case).

2017-03-08real_pathdup(): fix callsites that wanted it to die on errorJohannes Schindelin9-18/+18
In 4ac9006f832 (real_path: have callers use real_pathdup and strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path()) pattern to use real_pathdup() directly. The problem with this change is that real_path() calls strbuf_realpath() with die_on_error = 1 while real_pathdup() calls it with die_on_error = 0. Meaning that in cases where real_path() causes Git to die() with an error message, real_pathdup() is silent and returns NULL instead. The callers, however, are ill-prepared for that change, as they expect the return value to be non-NULL (and otherwise the function died with an appropriate error message). Fix this by extending real_pathdup()'s signature to accept the die_on_error flag and simply pass it through to strbuf_realpath(), and then adjust all callers after a careful audit whether they would handle NULLs well.

2017-03-07send-pack: read "unpack" status even on pack-objects failureJeff King1-0/+8
If the local pack-objects of a push fails, we'll tell the user about it. But one likely cause is that the remote index-pack stopped reading for some reason (because it didn't like our input, or encountered another error). In that case we'd expect the remote to report more details to us via the "unpack ..." status line. However, the current code just hangs up completely, and the user never sees it. Instead, let's call receive_unpack_status(), which will complain on stderr with whatever reason the remote told us. Note that if our pack-objects fails because the connection was severed or the remote just crashed entirely, then our packet_read_line() call may fail with "the remote end hung up unexpectedly". That's OK. It's a more accurate description than what we get now (which is just "some refs failed to push"). This should be safe from any deadlocks. At the point we make this call we'll have closed the writing end of the connection to the server (either by handing it off to a pack-objects which exited, explicitly in the stateless_rpc case, or by doing a half-duplex shutdown for a socket). So there should be no chance that the other side is waiting for the rest of our pack-objects input. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Likewise, when we got an unexpected packet from the other end, we complained with a vague message but did not actually show the packet. Let's fix that.

2017-03-07receive-pack: fix deadlock when we cannot create tmpdirJeff King1-1/+4
The err_fd descriptor passed to the unpack() function is intended to be handed off to the child index-pack, and our async muxer will read until it gets EOF. However, if we encounter an error before handing off the descriptor, we must manually close(err_fd). Otherwise we will be waiting for our muxer to finish, while the muxer is waiting for EOF on err_fd. We fixed an identical deadlock already in 49ecfa13f (receive-pack: close sideband fd on early pack errors, 2013-04-19). But since then, the function grew a new early-return in 722ff7f87 (receive-pack: quarantine objects until pre-receive accepts, 2016-10-03), when we fail to create a temporary directory.

That's 16 bytes on LP64, or 12 on ILP32. The correct "struct range" type has two longs, which is also 16 on LP64, but only 8 on ILP32. Likewise an IL32P64 system would experience the bug.

2017-03-03line-log.c: prevent crash during union of too many rangesAllan Xavier2-8/+17
The existing implementation of range_set_union does not correctly reallocate memory, leading to a heap overflow when it attempts to union more than 24 separate line ranges. For struct range_set *out to grow correctly it must have out->nr set to the current size of the buffer when it is passed to range_set_grow. However, the existing implementation of range_set_union only updates out->nr at the end of the function, meaning that it is always zero before this. This results in range_set_grow never growing the buffer, as well as some of the union logic itself being incorrect as !out->nr is always true. The reason why 24 is the limit is that the first allocation of size 1 ends up allocating a buffer of size 24 (due to the call to alloc_nr in ALLOC_GROW). This goes some way to explain why this hasn't been caught before. Fix the problem by correctly updating out->nr after reallocating the range_set. As this results in out->nr containing the same value as the variable o, replace o with out->nr as well. Finally, add a new test to help prevent the problem reoccurring in the future.

It's tempting to say: ./run v1.0.0 HEAD to see how we've sped up Git over the years. Unfortunately, this doesn't quite work because versions of Git prior to v1.7.0 lack bin-wrappers, so our "run" script doesn't correctly put them in the PATH. Worse, it means we silently find whatever other "git" is in the PATH, and produce test results that have no bearing on what we asked for. Let's fallback to the main git directory when bin-wrappers isn't present.

This is needed because the setup done by perf scripts keeps moving forward in time, and may use features that the older versions of git we are testing do not have. That commit used $MODERN_GIT to fix a case where we relied on the relatively recent --git-path option. But if you go back further still, there are more problems. Since 7501b5921 (perf: make the tests work in worktrees, 2016-05-13), we use "git -C", but versions of git older than 44e1e4d67 (git: run in a directory given with -C option, 2013-09-09) don't know about "-C". So testing an old version of git with a new version of t/perf will fail the setup step. We can fix this by using $MODERN_GIT during the setup; there's no need to use the antique version, since it doesn't affect the timings.

2017-03-02checkout: restrict @-expansions when finding branchJeff King2-1/+11
When we parse "git checkout $NAME", we try to interpret $NAME as a local branch-name. If it is, then we point HEAD to that branch. Otherwise, we detach the HEAD at whatever commit $NAME points to. We do the interpretation by calling strbuf_branchname(), and then blindly sticking "refs/heads/" on the front. This leads to nonsense results when expansions like "@{upstream}" or "@" point to something besides a local branch. We end up with a local branch name like "refs/heads/origin/master" or "refs/heads/HEAD". Normally this has no user-visible effect because those branches don't exist, and so we fallback to feeding the result to get_sha1(), which resolves them correctly. But as the new test in t3204 shows, there are corner cases where the effect is observable, and we check out the wrong local branch rather than detaching to the correct one.

This is obviously nonsense if the expansion is "HEAD" or a ref in refs/remotes/. The most obvious end-user effect is that creating or renaming a branch with an expansion may have confusing results (e.g., creating refs/heads/origin/master from "@{upstream}" when the operation should be disallowed). We can fix this by telling strbuf_branchname() that we are only interested in local expansions. Any unexpanded bits are then fed to check_ref_format(), which either disallows them (in the case of "@{upstream}") or lets them through ("refs/heads/@" is technically valid, if a bit silly).

2017-03-02interpret_branch_name: allow callers to restrict expansionsJeff King8-28/+69
The interpret_branch_name() function converts names like @{-1} and @{upstream} into branch names. The expanded ref names are not fully qualified, and may be outside of the refs/heads/ namespace (e.g., "@" expands to "HEAD", and "@{upstream}" is likely to be in "refs/remotes/"). This is OK for callers like dwim_ref() which are primarily interested in resolving the resulting name, no matter where it is. But callers like "git branch" treat the result as a branch name in refs/heads/. When we expand to a ref outside that namespace, the results are very confusing (e.g., "git branch @" tries to create refs/heads/HEAD, which is nonsense). Callers can't know from the returned string how the expansion happened (e.g., did the user really ask for a branch named "HEAD", or did we do a bogus expansion?). One fix would be to return some out-parameters describing the types of expansion that occurred. This has the benefit that the caller can generate precise error messages ("I understood @{upstream} to mean origin/master, but that is a remote tracking branch, so you cannot create it as a local name"). However, out-parameters make the function interface somewhat cumbersome. Instead, let's do the opposite: let the caller tell us which elements to expand. That's easier to pass in, and none of the callers give more precise error messages than "@{upstream} isn't a valid branch name" anyway (which should be sufficient). The strbuf_branchname() function needs a similar parameter, as most of the callers access interpret_branch_name() through it. We can break the callers down into two groups: 1. Callers that are happy with any kind of ref in the result. We pass "0" here, so they continue to work without restrictions. This includes merge_name(), the reflog handling in add_pending_object_with_path(), and substitute_branch_name(). This last is what powers dwim_ref(). 2. Callers that have funny corner cases (mostly in git-branch and git-checkout). These need to make use of the new parameter, but I've left them as "0" in this patch, and will address them individually in follow-on patches.

2017-03-02interpret_branch_name(): handle auto-namelen for @{-1}Jeff King2-1/+10
The interpret_branch_name() function takes a ptr/len pair for the name, but you can pass "0" for "namelen", which will cause it to check the length with strlen(). However, before we do that auto-namelen magic, we call interpret_nth_prior_checkout(), which gets fed the bogus "0". This was broken by 8cd4249c4 (interpret_branch_name: always respect "namelen" parameter, 2014-01-15). Though to be fair to that commit, it was broken in the _opposite_ direction before, where we would always treat "name" as a string even if a length was passed. You can see the bug with "git log -g @{-1}". That code path always passes "0", and without this patch it cannot figure out which branch's reflog to show. We can fix it by a small reordering of the code. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-03-02diff: do not short-cut CHECK_SIZE_ONLY check in diff_populate_filespec()Junio C Hamano2-1/+27
Callers of diff_populate_filespec() can choose to ask only for the size of the blob without grabbing the blob data, and the function, after running lstat() when the filespec points at a working tree file, returns by copying the value in size field of the stat structure into the size field of the filespec when this is the case. However, this short-cut cannot be taken if the contents from the path needs to go through convert_to_git(), whose resulting real blob data may be different from what is in the working tree file. As "git diff --quiet" compares the .size fields of filespec structures to skip content comparison, this bug manifests as a false "there are differences" for a file that needs eol conversion, for example.

2017-03-02add--interactive: fix missing file prompt for patch mode with "-i"Jeff King2-4/+22
When invoked as "git add -i", each menu interactive menu option prompts the user to select a list of files. This includes the "patch" option, which gets the list before starting the hunk-selection loop. As "git add -p", it behaves differently, and jumps straight to the hunk selection loop. Since 0539d5e6d (i18n: add--interactive: mark patch prompt for translation, 2016-12-14), the "add -i" case mistakenly jumps to straight to the hunk-selection loop. Prior to that commit the distinction between the two cases was managed by the $patch_mode variable. That commit used $patch_mode for something else, and moved the old meaning to the "$cmd" variable. But it forgot to update the $patch_mode check inside patch_update_cmd() which controls the file-list behavior. The simplest fix would be to change that line to check $cmd. But while we're here, let's use a less obscure name for this flag: $patch_mode_only, a boolean which tells whether we are in full-interactive mode or only in patch-mode.

2017-02-28http: attempt updating base URL only if no errorJonathan Tan3-0/+21
http.c supports HTTP redirects of the form http://foo/info/refs?service=git-upload-pack -> http://anything -> http://bar/info/refs?service=git-upload-pack (that is to say, as long as the Git part of the path and the query string is preserved in the final redirect destination, the intermediate steps can have any URL). However, if one of the intermediate steps results in an HTTP exception, a confusing "unable to update url base from redirection" message is printed instead of a Curl error message with the HTTP exception code. This was introduced by 2 commits. Commit c93c92f ("http: update base URLs when we see redirects", 2013-09-28) introduced a best-effort optimization that required checking if only the "base" part of the URL differed between the initial request and the final redirect destination, but it performed the check before any HTTP status checking was done. If something went wrong, the normal code path was still followed, so this did not cause any confusing error messages until commit 6628eb4 ("http: always update the base URL for redirects", 2016-12-06), which taught http to die if the non-"base" part of the URL differed. Therefore, teach http to check the HTTP status before attempting to check if only the "base" part of the URL differed. This commit teaches http_request_reauth to return early without updating options->base_url upon an error; the only invoker of this function that passes a non-NULL "options" is remote-curl.c (through "http_get_strbuf"), which only uses options->base_url for an informational message in the situations that this commit cares about (that is, when the return value is not HTTP_OK). The included test checks that the redirect scheme at the beginning of this commit message works, and that returning a 502 in the middle of the redirect scheme produces the correct result. Note that this is different from the test in commit 6628eb4 ("http: always update the base URL for redirects", 2016-12-06) in that this commit tests that a Git-shaped URL (http://.../info/refs?service=git-upload-pack) works, whereas commit 6628eb4 tests that a non-Git-shaped URL (http://.../info/refs/foo?service=git-upload-pack) does not work (even though Git is processing that URL) and is an error that is fatal, not silently swallowed.

2017-02-28docs/diffcore: unquote "Complete Rewrites" in headersPatrick Steinhardt1-4/+4
The gitdiffcore documentation quotes the term "Complete Rewrites" in headers for no real gain. This would make sense if the term could be easily confused if not properly grouped together. But actually, the term is quite obvious and thus does not really need any quoting, especially regarding that it is not used anywhere else. But more importanly, this brings up a bug when rendering man pages: when trying to render quotes inside of a section header, we end up with quotes which have been misaligned to the end of line. E.g. diffcore-break: For Splitting Up Complete Rewrites -------------------------------------------------- renders as DIFFCORE-BREAK: FOR SPLITTING UP COMPLETE REWRITES"" , which is obviously wrong. While this is fixable for the man pages by using double-quotes (e.g. ""COMPLETE REWRITES""), this again breaks it for our generated HTML pages. So fix the issue by simply dropping quotes inside of section headers, which is currently only done for the term "Complete Rewrites".

This commit is technically being overzealous, we could do better by making a mock cvs commit as root and run the tests if that works, but I don't see any compelling reason to bend over backwards to run these tests in all cases, just skipping them as root seems good enough. 1.

2017-02-27http: add an "auto" mode for http.emptyauthJeff King1-5/+45
This variable needs to be specified to make some types of non-basic authentication work, but ideally this would just work out of the box for everyone. However, simply setting it to "1" by default introduces an extra round-trip for cases where it _isn't_ useful. We end up sending a bogus empty credential that the server rejects. Instead, let's introduce an automatic mode, that works like this: 1. We won't try to send the bogus credential on the first request. We'll wait to get an HTTP 401, as usual. 2. After seeing an HTTP 401, the empty-auth hack will kick in only when we know there is an auth method available that might make use of it (i.e., something besides "Basic" or "Digest"). That should make it work out of the box, without incurring any extra round-trips for people hitting Basic-only servers. This _does_ incur an extra round-trip if you really want to use "Basic" but your server advertises other methods (the emptyauth hack will kick in but fail, and then Git will actually ask for a password). The auto mode may incur an extra round-trip over setting http.emptyauth=true, because part of the emptyauth hack is to feed this blank password to curl even before we've made a single request.

The parse_config_key() function was introduced to make it easier to match "section.subsection.key" variables. It also handles the simpler "section.key", and the caller is responsible for distinguishing the two from its out-parameters. Most callers who _only_ want "section.key" would just use a strcmp(var, "section.key"), since there is no parsing required. However, they may still use parse_config_key() if their "section" variable isn't a constant (an example of this is in parse_hide_refs_config). Using the parse_config_key is a bit clunky, though: const char *subsection; int subsection_len; const char *key; if (!parse_config_key(var, section, &subsection, &subsection_len, &key) && !subsection) { /* matched! */ } Instead, let's treat a NULL subsection as an indication that the caller does not expect one. That lets us write: const char *key; if (!parse_config_key(var, section, NULL, NULL, &key)) { /* matched! */ } Existing callers should be unaffected, as passing a NULL subsection would currently segfault.

The parsing of one-shot assignments of configuration variables that come from the command line historically was quite loose and allowed anything to pass. It also downcased everything in the variable name, even a three-level <section>.<subsection>.<variable> name in which the <subsection> part must be treated in a case sensitive manner. Existing git_config_parse_key() helper is used to parse the variable name that comes from the command line, i.e. "git config VAR VAL", and handles these details correctly. Replace the strbuf_tolower() call in git_config_parse_parameter() with a call to it to correct both issues. git_config_parse_key() does a bit more things that are not necessary for the purpose of this codepath (e.g. it allocates a separate buffer to return the canonicalized variable name because it takes a "const char *" input), but we are not in a performance-critical codepath here.

We reject an empty name when formatting a strict ident, but don't notice an all-crud one because our check happens before the crud-removal step. We could skip past the crud before checking for an empty name, but let's make it a separate code path, for two reasons. One is that we can give a more specific error message.

2017-02-23ident: handle NULL email when complaining of empty nameJeff King2-13/+33
If we see an empty name, we complain about and mention the matching email in the error message (to give it some context). However, the "email" pointer may be NULL here if we were planning to fill it in later from ident_default_email(). This was broken by 59f929596 (fmt_ident: refactor strictness checks, 2016-02-04). Prior to that commit, we would look up the default name and email before doing any other actions. So one solution would be to go back to that. However, we can't just do so blindly. The logic for handling the "!email" condition has grown since then. In particular, looking up the default email can die if getpwuid() fails, but there are other errors that should take precedence. Commit 734c7789a (ident: check for useConfigOnly before auto-detection of name/email, 2016-03-30) reordered the checks so that we prefer the error message for useConfigOnly. Instead, we can observe that while the name-handling depends on "email" being set, the reverse is not true. So we can simply set up the email variable first. This does mean that if both are bogus, we'll complain about the email before the name. But between the two, there is no reason to prefer one over the other.

2017-02-23http: restrict auth methods to what the server advertisesJeff King1-0/+2
By default, we tell curl to use CURLAUTH_ANY, which does not limit its set of auth methods. However, this results in an extra round-trip to the server when authentication is required. After we've fed the credential to curl, it wants to probe the server to find its list of available methods before sending an Authorization header. We can shortcut this by limiting our http_auth_methods by what the server told us it supports. In some cases (such as when the server only supports Basic), that lets curl skip the extra probe request. The end result should look the same to the user, but you can use GIT_TRACE_CURL to verify the sequence of requests: GIT_TRACE_CURL=1 \ git ls-remote https://example.com/repo.git \ 2>&1 >/dev/null | egrep '(Send|Recv) header: (GET|HTTP|Auth)' Before this patch, hitting a Basic-only server like github.com results in: Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1 Recv header: HTTP/1.1 401 Authorization Required Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1 Recv header: HTTP/1.1 401 Authorization Required Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1 Send header: Authorization: Basic <redacted> Recv header: HTTP/1.1 200 OK And after: Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1 Recv header: HTTP/1.1 401 Authorization Required Send header: GET /repo.git/info/refs?service=git-upload-pack HTTP/1.1 Send header: Authorization: Basic <redacted> Recv header: HTTP/1.1 200 OK The possible downsides are: - This only helps for a Basic-only server; for a server with multiple auth options, curl may still send a probe request to see which ones are available (IOW, there's no way to say "don't probe, I already know what the server will say"). - The http_auth_methods variable is global, so this will apply to all further requests. That's acceptable for Git's usage of curl, though, which also treats the credentials as global. I.e., in any given program invocation we hit only one conceptual server (we may be redirected at the outset, but in that case that's whose auth_avail field we'd see).

2017-02-17tempfile: set errno to a known value before calling ferror()Jeff King1-2/+7
In close_tempfile(), we return an error if ferror() indicated a previous failure, or if fclose() failed. In the latter case, errno is set and it is useful for callers to report it. However, if _only_ ferror() triggers, then the value of errno is based on whatever syscall happened to last fail, which may not be related to our filehandle at all. A caller cannot tell the difference between the two cases, and may use "die_errno()" or similar to report a nonsense errno value. One solution would be to actually pass back separate return values for the two cases, so a caller can write a more appropriate message for each case. But that makes the interface clunky. Instead, let's just set errno to the generic EIO in this case. That's not as descriptive as we'd like, but at least it's predictable. So it's better than the status quo in all cases but one: when the last syscall really did involve a failure on our filehandle, we'll be wiping that out. But that's a fragile thing for us to rely on. In any case, we'll let the errno result from fclose() take precedence over our value, as we know that's recent and accurate (and many I/O errors will persist through the fclose anyway).

2017-02-16tempfile: avoid "ferror | fclose" trickJeff King1-6/+2
The current code wants to record an error condition from either ferror() or fclose(), but makes sure that we always call both functions. So it can't use logical-OR "||", which would short-circuit when ferror() is true. Instead, it uses bitwise-OR "|" to evaluate both functions and set one or more bits in the "err" flag if they reported a failure. Unlike logical-OR, though, bitwise-OR does not introduce a sequence point, and the order of evaluation for its operands is unspecified. So a compiler would be free to generate code which calls fclose() first, and then ferror() on the now-freed filehandle. There's no indication that this has happened in practice, but let's write it out in a way that follows the standard.

2017-02-14grep: treat revs the same for --untracked as for --no-indexJeff King2-6/+6
git-grep has always disallowed grepping in a tree (as opposed to the working directory) with both --untracked and --no-index. But we traditionally did so by first collecting the revs, and then complaining when any were provided. The --no-index option recently learned to detect revs much earlier. This has two user-visible effects: - we don't bother to resolve revision names at all. So when there's a rev/path ambiguity, we always choose to treat it as a path. - likewise, when you do specify a revision without "--", the error you get is "no such path" and not "--untracked cannot be used with revs". The rationale for doing this with --no-index is that it is meant to be used outside a repository, and so parsing revs at all does not make sense. This patch gives --untracked the same treatment. While it _is_ meant to be used in a repository, it is explicitly about grepping the non-repository contents. Telling the user "we found a rev, but you are not allowed to use revs" is not really helpful compared to "we treated your argument as a path, and could not find it".
