| * fetch-pack: mention server version with verbose outputJeff King2012-08-13
| | | | | | | | | | | | | | | | | | | | Fetch-pack's verbose mode is more of a debugging mode (and in fact takes two "-v" arguments to trigger via the porcelain layer). Let's mention the server version as another possible item of interest. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already take care to parse key/value capabilities like "foo=bar", but the code does not provide a good way of actually finding out what is on the right-hand side of the "=". A server using "parse_feature_request" could accomplish this with some extra parsing. You must skip past the "key" portion manually, check for "=" versus NUL or space, and then find the length by searching for the next space (or NUL). But clients can't even do that, since the "server_supports" interface does not even return the pointer. Instead, let's have our parser share more information by providing a pointer to the value and its length. The "parse_feature_value" function returns a pointer to the feature's value portion, along with the length of the value. If the feature is missing, NULL is returned. If it does not have an "=", then a zero-length value is returned. Similarly, "server_feature_value" behaves in the same way, but always checks the static server_feature_list variable. We can then implement "server_supports" in terms of "server_feature_value". We cannot implement the original "parse_feature_request" in terms of our new function, because it returned a pointer to the beginning of the feature. However, no callers actually cared about the value of the returned pointer, so we can simplify it to a boolean just as we do for "server_supports".

| * do not send client agent unless server does firstJeff King2012-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ff5effdf taught both clients and servers of the git protocol to send an "agent" capability that just advertises their version for statistics and debugging purposes. The protocol-capabilities.txt document however indicates that the client's advertisement is actually a response, and should never include capabilities not mentioned in the server's advertisement. Adding the unconditional advertisement in the server programs was OK, then, but the clients broke the protocol. The server implementation of git-core itself does not care, but at least one does: the Google Code git server (or any server using Dulwich), will hang up with an internal error upon seeing an unknown capability. Instead, each client must record whether we saw an agent string from the server, and respond with its agent only if the server mentioned it first.

| * send-pack: fix capability-sending logicJeff King2012-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we have capabilities to send to the server, we send the regular "want" line followed by a NUL, then the capabilities; otherwise, we do not even send the NUL. However, when checking whether we want to send the "quiet" capability, we check args->quiet, which is wrong. That flag only tells us whether the client side wanted to be quiet, not whether the server supports it (originally, in c207e34f, it meant both; however, that was later split into two flags by 01fdc21f). We still check the right flag when actually printing "quiet", so this could only have two effects: 1. We might send the trailing NUL when we do not otherwise need to. In theory, an antique pre-capability implementation of git might choke on this (since the client is instructed never to respond with capabilities that the server has not first advertised). 2. We might also want to send the quiet flag if the args->progress flag is false, but this code path would not trigger in that instance. In practice, it almost certainly never matters. The report-status capability dates back to 2005. Any real-world server is going to advertise that, and we will always respond with at least that capability.

| * include agent identifier in capability stringJeff King2012-08-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of having the client advertise a particular version number in the git protocol, we have managed extensions and backwards compatibility by having clients and servers advertise capabilities that they support. This is far more robust than having each side consult a table of known versions, and provides sufficient information for the protocol interaction to complete. However, it does not allow servers to keep statistics on which client versions are being used. This information is not necessary to complete the network request (the capabilities provide enough information for that), but it may be helpful to conduct a general survey of client versions in use. We already send the client version in the user-agent header for http requests; adding it here allows us to gather similar statistics for non-http requests.

Looking for "git-*.txt" would be more accurate, but would miss a few commands like "gitweb" and "gitk". Fortunately, Documentation/Makefile already knows what this list is, so we can just ask it. Annoyingly, we still have to post-process its output a little, since make will print extra cruft like "GIT-VERSION-FILE is up to date" to stdout. Now that our list is accurate, we can remove all of the ugly special-cases. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

It is OK for commonly used prerequisites to be always tested during start-up of a test script by having a codeblock that tests a feature and calls test_set_prereq, but for an uncommon feature, forcing 90% of scripts to pay the same probing overhead for prerequisite they do not care about is wasteful. Introduce a mechanism to probe the prerequiste lazily. Changes are: - test_lazy_prereq () function, which takes the name of the prerequisite it probes and the script to probe for it, is added. This only registers the name of the prerequiste that can be lazily probed and the script to eval (without running). - test_have_prereq() function (which is used by test_expect_success and also can be called directly by test scripts) learns to look at the list of prerequisites that can be lazily probed, and the prerequisites that have already been probed that way. When asked for a prerequiste that can be but haven't been probed, the script registered with an earlier call to test_lazy_prereq is evaluated and the prerequisite is set. - test_run_lazy_prereq_() function is a helper to run the probe script with the same kind of sandbox as regular tests, helped by Jeff King. Update the codeblock to probe and set SYMLINKS prerequisite using the new mechanism as an example. Signed-off-by: Junio C Hamano <gitster@pobox.com>

The original thinking was that the presence of a leftover temporary file should be an unusual occurrence that may indicate an earlier failure of some sort, and the user may want to be reminded of it. Removing an unnecessary loose object file, on the other hand, is just part of the normal operation. That is why the former is always printed out and the latter only when -v is used. But neither report is particularly useful. Hide both of these behind the "-v" option for consistency.

So let's have fsck warn if it it seen. As in the previous commit, we test both blob and submodule entries to future-proof the test suite against the implementation depending on connectivity to notice the error.

If we attempt to do so, it is much more likely that it is a bug, since we use the null sha1 as a sentinel value to mean "not valid". The presence of null sha1s in the index (which can come from, among other things, "update-index --cacheinfo", or by reading a corrupted tree) can cause problems for later readers, because they cannot distinguish the literal null sha1 from its use a sentinel value. For example, "git diff-files" on such an entry would make it appear as if it is stat-dirty, and until recently, the diff code assumed such an entry meant that we should be diffing a working tree file rather than a blob. Ideally, we would stop such entries from entering even our in-core index. However, we do sometimes legitimately add entries with null sha1s in order to represent these sentinel situations; simply forbidding them in add_index_entry breaks a lot of the existing code. However, we can at least make sure that our in-core sentinel representation never makes it to disk. To be thorough, we will test an attempt to add both a blob and a submodule entry. In the former case, we might run into problems anyway because we will be missing the blob object. But in the latter case, we do not enforce connectivity across gitlink entries, making this our only point of enforcement. The current implementation does not care which type of entry we are seeing, but testing both cases helps future-proof the test suite in case that changes.

This struct has a sha1 to represent the sha1 of the content at that path, as well as a sha1_valid member which indicates whether its sha1 field is actually useful. If sha1_valid is not true, then the filespec represents a working tree file (e.g., for the no-index case, or for when the index is not up-to-date). The diff_filespec is only used internally, though. At the interfaces to the diff subsystem, callers feed the sha1 directly, and we create a diff_filespec from it. It's at that point that we look at the sha1 and decide whether it is valid or not; callers may pass the null sha1 as a sentinel value to indicate that it is not. We should not typically see the null sha1 coming from any other source (e.g., in the index itself, or from a tree). However, a corrupt tree might have a null sha1, which would cause "diff --patch" to accidentally diff the working tree version of a file instead of treating it as a blob. This patch extends the edges of the diff interface to accept a "sha1_valid" flag whenever we accept a sha1, and to use that flag when creating a filespec. In some cases, this means passing the flag through several layers, making the code change larger than would be desirable. One alternative would be to simply die() upon seeing corrupted trees with null sha1s. However, this fix more directly addresses the problem (while bogus sha1s in a tree are probably a bad thing, it is really the sentinel confusion sending us down the wrong code path that is what makes it devastating). And it means that git is more capable of examining and debugging these corrupted trees. For example, you can still "diff --raw" such a tree to find out when the bogus entry was introduced; you just cannot do a "--patch" diff (just as you could not with any other corrupted tree, as we do not have any content to diff).

[Noticed by Christoph.] * It is too liberal in its matching, and happily matches the start of one quoted chunk against the end of another, or even just something that looks like such an end. [Noticed by Junio.] * It fundamentally cannot cope with encodings that are not a superset of ASCII, nor several (incompatible) encodings in the same header. This patch fixes the first two by doing a more careful decoding of the outer quoting (e.g. "=AB" to represent an octet whose value is 0xAB). Fixing the fundamental issues is left for a future, more intrusive, patch.

However, it fails to account for the fact that PATH_INFO has already been URL-decoded by the web server, but the value returned by $cgi->url() has not been. This causes the stripping to fail whenever the URL contains encoded characters. To see this in action, setup gitweb as a DirectoryIndex and then use it on a repository with a directory containing a space in the name. Navigate to tree view, examine the gitweb generated html and you'll see a link such as: <a href="/test.git/tree/HEAD:/directory with spaces">directory with spaces</a> When clicked on, the browser will URL-encode this link, giving a $cgi->url() of the form: /test.git/tree/HEAD:/directory%20with%20spaces While PATH_INFO is: /test.git/tree/HEAD:/directory with spaces Fix this by calling unescape() on both $my_url and $my_uri before stripping PATH_INFO from them.
