e2aba8ba	2019-06-15T20:45:22	wildmatch: explicitly cast to int
759ec7d4	2019-06-15T22:01:00	win32: cast GetProcAddress to void * before casting GetProcAddress is prototyped to return a `FARPROC`, which is meant to be a generic function pointer. It's literally `int (FAR WINAPI * FARPROC)()` which gcc complains if you attempt to cast to a `void ()(GIT_SRWLOCK )`. Cast to a `void *` before casting to avoid warnings about the arguments.

3dd1942b	2019-06-15T20:43:13	win32: don't re-define RtlCaptureStackBackTrace RtlCaptureStackBackTrace is well-defined in Windows, no need to redefine it.
cc9e47c9	2019-06-15T18:51:40	win32: support upgrading warnings to errors (/WX) For MSVC, support warnings as errors by providing the /WX compiler flags. (/WX is the moral equivalent of -Werror.) Disable warnings as errors ass part of xdiff, since it contains warnings. But as a component of git itself, we want to avoid skew and keep our implementation as similar as possible to theirs. We'll work with upstream to fix these issues, but in the meantime, simply let those continue to warn.
f6530438	2019-05-25T16:44:59	win32: stop inlining file_attribute_to_stat Move `git_win32__file_attribute_to_stat` to a regular function instead of an inlined function. This helps avoid header ordering issues and declarations.

f7597410	2019-05-21T10:57:30	netops: safely cast to int Only read at most INT_MAX from the underlying stream, so that we can accurately return the number of bytes read. Since callers are not guaranteed to get as many bytes as requested (due to availability of input), this is safe and callers should call in a loop until EOF.

8c925ef8	2019-05-21T14:30:28	smart protocol: validate progress message length Ensure that the server has not sent us overly-large sideband messages (ensure that they are no more than `INT_MAX` bytes), then cast to `int`.

2375be48	2019-05-21T12:57:28	tree: return `size_t` for treebuilder entrycount We keep the treebuilder entrycount as a `size_t` - return that instead of downcasting to an `unsigned int`. Callers who were storing this value in an `unsigned int` will continue to downcast themselves, so there should be no behavior change for callers.
ad6f2153	2019-05-21T12:50:46	utf8: use size_t for length of buffer The `git__utf8_charlen` now takes `size_t` as the buffer length, since it contains the full length of the buffer at the current position. It now returns `-1` in all cases where utf8 codepoints are invalid, since callers only care about a valid length of a sequence of codepoints, or if the current position is not valid utf8.

fef847ae	2019-06-15T15:47:41	Merge pull request #5110 from pks-t/pks/wildmatch Replace fnmatch with wildmatch
13ded47c	2019-06-13T19:57:17	fnmatch: remove unused code The `fnmatch` code has now been completely replaced by `wildmatch`, same as upstream git.git has been doing in 2014. Remove it.
05f9986a	2019-06-14T08:06:05	attr_file: convert to use `wildmatch` Upstream git has converted to use `wildmatch` instead of `fnmatch`. Convert our gitattributes logic to use `wildmatch` as the last user of `fnmatch`. Please, don't expect I know what I'm doing here: the fnmatch parser is one of the most fun things to play around with as it has a shtload of weird cases. In all honesty, I'm simply relying on our tests that are by now rather comprehensive in that area. The conversion actually fixes compatibility with how git.git parser "" patterns when the given path does not contain any directory separators. Previously, a pattern "*.foo" erroneously wouldn't match a file "x.foo", while git.git would match. Remove the new-unused LEADINGDIR/NOLEADINGDIR flags for `git_attr_fnmatch`.
5811e3ba	2019-06-13T19:16:32	config_file: use `wildmatch` to evaluate conditionals We currently use `p_fnmatch` to compute whether a given "gitdir:" or "gitdir/i:" conditional matches the current configuration file path. As git.git has moved to use `wildmatch` instead of `p_fnmatch` throughout its complete codebase, we evaluate conditionals inconsistently with git.git in some special cases. Convert `p_fnmatch` to use `wildmatch`. The `FNM_LEADINGDIR` flag cannot be translated to `wildmatch`, but in fact git.git doesn't use it here either. And in fact, dropping it while we go increases compatibility with git.git.
cf1a114b	2019-06-13T19:10:22	config_file: do not include trailing '/' for "gitdir" conditionals When evaluating "gitdir:" and "gitdir/i:" conditionals, we currently compare the given pattern with the value of `git_repository_path`. Thing is though that `git_repository_path` returns the gitdir path with trailing '/', while we actually need to match against the gitdir without it. Fix this issue by stripping the trailing '/' previous to matching. Add various tests to ensure we get this right.
5d987f7d	2019-06-13T19:00:06	config_file: refactor `do_match_gitdir` to improve readability The function `do_match_gitdir` has some horribly named parameters and variables. Rename them to improve readability. Furthermore, fix a potentially undetected out-of-memory condition when appending "**" to the pattern.
de70bb46	2019-06-13T15:27:22	global: convert trivial `fnmatch` users to use `wildcard` Upstream git.git has converted its codebase to use wildcard in favor of fnmatch in commit 70a8fc999d (stop using fnmatch (either native or compat), 2014-02-15). To keep our own regex-matching in line with what git does, convert all trivial instances of `fnmatch` usage to use `wildcard`, instead. Trivial usage is defined to be use of `fnmatch` with either no flags or flags that have a 1:1 equivalent in wildmatch (PATHNAME, IGNORECASE).
451df793	2019-06-13T15:20:23	posix: remove implicit include of "fnmatch.h" We're about to phase out our bundled fnmatch implementation as git.git has moved to wildmatch long ago in 2014. To make it easier to spot which files are stilll using fnmatch, remove the implicit "fnmatch.h" include in "posix.h" and instead include it explicitly.
a9f57629	2019-06-13T15:03:00	wildmatch: import wildmatch from git.git In commit 70a8fc999d (stop using fnmatch (either native or compat), 2014-02-15), upstream git has switched over all code from their internal fnmatch copy to its new wildmatch code. We haven't followed suit, and thus have developed some incompatibilities in how we match regular expressions. Import git's wildmatch from v2.22.0 and add a test suite based on their t3070-wildmatch.sh tests.
2d85c7e8	2019-06-14T14:12:19	posix: remove `p_fallocate` abstraction By now, we have repeatedly failed to provide a nice cross-platform implementation of `p_fallocate`. Recent tries to do that escalated quite fast to a set of different CMake checks, implementations, fallbacks, etc., which started to look real awkward to maintain. In fact, `p_fallocate` had only been introduced in commit 4e3949b73 (tests: test that largefiles can be read through the tree API, 2019-01-30) to support a test with large files, but given the maintenance costs it just seems not to be worht it. As we have removed the sole user of `p_fallocate` in the previous commit, let's drop it altogether.
94fc83b6	2019-06-13T16:48:35	cmake: Modulize our TLS & hash detection The interactions between `USE_HTTPS` and `SHA1_BACKEND` have been streamlined. Previously we would have accepted not quite working configurations (like, `-DUSE_HTTPS=OFF -DSHA1_BACKEND=OpenSSL`) and, as the OpenSSL detection only ran with `USE_HTTPS`, the link would fail. The detection was moved to a new `USE_SHA1`, modeled after `USE_HTTPS`, which takes the values "CollisionDetection/Backend/Generic", to better match how the "hashing backend" is selected, the default (ON) being "CollisionDetection". Note that, as `SHA1_BACKEND` is still used internally, you might need to check what customization you're using it for.
c0dd7122	2019-06-06T16:48:04	apply: add an options struct initializer
0b5ba0d7	2019-06-06T16:36:23	Rename opt init functions to `options_init` In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.

fb529a01	2019-06-11T22:03:29	http-parser: use our bundled http-parser by default Our bundled http-parser includes bugfixes, therefore we should prefer our http-parser until such time as we can identify that the system http-parser has these bugfixes (using a version check). Since these bugs are - at present - minor, retain the ability for users to force that they want to use the system http-parser anyway. This does change the cmake specification so that people _must_ opt-in to the new behavior knowingly.

3b517351	2019-06-07T10:13:34	attr_file: remove invalid TODO comment In our attributes pattern parsing code, we have a comment that states we might have to convert '\' characters to '/' to have proper POSIX paths. But in fact, '\' characters are valid inside the string and act as escape mechanism for various characters, which is why we never want to convert those to POSIX directory separators. Furthermore, gitignore patterns are specified to only treat '/' as directory separators. Remove the comment to avoid future confusion.
b3b6a39d	2019-06-07T11:12:54	attr_file: account for escaped escapes when searching trailing space When determining the trailing space length, we need to honor whether spaces are escaped or not. Currently, we do not check whether the escape itself is escaped, though, which might generate an off-by-one in that case as we will simply treat the space as escaped. Fix this by checking whether the backslashes preceding the space are themselves escaped.
10ac298c	2019-06-07T11:12:42	attr_file: fix unescaping of escapes required for fnmatch When parsing attribute patterns, we will eventually unescape the parsed pattern. This is required because we require custom escapes for whitespace characters, as normally they are used to terminate the current pattern. Thing is, we don't only unescape those whitespace characters, but in fact all escaped sequences. So for example if the pattern was "\", we unescape that to "". As this is directly passed to fnmatch(3) later, fnmatch would treat it as a simple glob matching all files where it should instead only match a file with name "*". Fix the issue by unescaping spaces, only. Add a bunch of tests to exercise escape parsing.
eb146e58	2019-06-07T09:17:23	attr_file: properly handle escaped '\' when searching non-escaped spaces When parsing attributes, we need to search for the first unescaped whitespace character to determine where the pattern is to be cut off. The scan fails to account for the case where the escaping '\' character is itself escaped, though, and thus we would not recognize the cut-off point in patterns like "\\ ". Refactor the scanning loop to remember whether the last character was an escape character. If it was and the next character is a '\', too, then we will reset to non-escaped mode again. Thus, we now handle escaped whitespaces as well as escaped wildcards correctly.
f7c6795f	2019-06-07T10:20:35	path: only treat paths starting with '\' as absolute on Win32 Windows-based systems treat paths starting with '\' as absolute, either referring to the current drive's root (e.g. "\foo" might refer to "C:\foo") or to a network path (e.g. "\\host\foo"). On the other hand, (most?) systems that are not based on Win32 accept backslashes as valid characters that may be part of the filename, and thus we cannot treat them to identify absolute paths. Change the logic to only paths starting with '\' as absolute on the Win32 platform. Add tests to avoid regressions and document behaviour.

230a451e	2019-06-10T13:54:11	sha1dc: update to fix endianess issues on AIX/HP-UX Update our copy of sha1dc to the upstream commit 855827c (Detect endianess on HP-UX, 2019-05-09).

956ba48b	2019-03-14T10:36:40	http: increase the replay count Increase the permissible replay count; with multiple-step authentication schemes (NTLM, Negotiate), proxy authentication and redirects, we need to be mindful of the number of steps it takes to get connected. 7 seems high but can be exhausted quickly with just a single authentication failure over a redirected multi-state authentication pipeline.
ee3d35cf	2019-04-07T19:15:21	http: support https for proxies
3d11b6c5	2019-03-11T20:36:09	winhttp: support default credentials for proxies We did not properly support default credentials for proxies, only for destination servers. Refactor the credential handling to support sending either username/password _or_ default credentials to either the proxy or the destination server. This actually shares the authentication logic between proxy servers and destination servers. Due to copy/pasta drift over time, they had diverged. Now they share a common logic which is: first, use credentials specified in the URL (if there were any), treating empty username and password (ie, "http://:@foo.com/") as default credentials, for compatibility with git. Next, call the credential callbacks. Finally, fallback to WinHTTP compatibility layers using built-in authentication like we always have. Allowing default credentials for proxies requires moving the security level downgrade into the credential setting routines themselves. We will update our security level to "high" by default which means that we will never send default credentials without prompting. (A lower setting, like the WinHTTP default of "medium" would allow WinHTTP to handle credentials for us, despite what a user may have requested with their structures.) Now we start with "high" and downgrade to "low" only after a user has explicitly requested default credentials.
c6ab183e	2019-03-11T11:43:08	net: rename gitno_connection_data to git_net_url "Connection data" is an imprecise and largely incorrect name; these structures are actually parsed URLs. Provide a parser that takes a URL string and produces a URL structure (if it is valid). Separate the HTTP redirect handling logic from URL parsing, keeping a `gitno_connection_data_handle_redirect` whose only job is redirect handling logic and does not parse URLs itself.
7ea8630e	2019-04-07T20:11:59	http: free auth context on failure When we send HTTP credentials but the server rejects them, tear down the authentication context so that we can start fresh. To maintain this state, additionally move all of the authentication handling into `on_auth_required`.
005b5bc2	2019-04-07T17:55:23	http: reconnect to proxy on connection close When we're issuing a CONNECT to a proxy, we expect to keep-alive to the proxy. However, during authentication negotiations, the proxy may close the connection. Reconnect if the server closes the connection.
d171fbee	2019-04-07T17:40:23	http: allow server to drop a keepalive connection When we have a keep-alive connection to the server, that server may legally drop the connection for any reason once a successful request and response has occurred. It's common for servers to drop the connection after some amount of time or number of requests have occurred.
9af1de5b	2019-03-24T20:49:57	http: stop on server EOF We stop the read loop when we have read all the data. We should also consider the server's feelings. If the server hangs up on us, we need to stop our read loop. Otherwise, we'll try to read from the server - and fail - ad infinitum.
539e6293	2019-03-22T19:06:46	http: teach auth mechanisms about connection affinity Instead of using `is_complete` to decide whether we have connection or request affinity for authentication mechanisms, set a boolean on the mechanism definition itself.
3e0b4b43	2019-03-22T18:52:03	http: maintain authentication across connections For request-based authentication mechanisms (Basic, Digest) we should keep the authentication context alive across socket connections, since the authentication headers must be transmitted with every request. However, we should continue to remove authentication contexts for mechanisms with connection affinity (NTLM, Negotiate) since we need to reauthenticate for every socket connection.
ce72ae95	2019-03-22T10:53:30	http: simplify authentication mechanisms Hold an individual authentication context instead of trying to maintain all the contexts; we can select the preferred context during the initial negotiation. Subsequent authentication steps will re-use the chosen authentication (until such time as it's rejected) instead of trying to manage multiple contexts when all but one will never be used (since we can only authenticate with a single mechanism at a time.) Also, when we're given a 401 or 407 in the middle of challenge/response handling, short-circuit immediately without incrementing the retry count. The multi-step authentication is expected, and not a "retry" and should not be penalized as such. This means that we don't need to keep the contexts around and ensures that we do not unnecessarily fail for too many retries when we have challenge/response auth on a proxy and a server and potentially redirects in play as well.

79fc8281	2019-03-21T16:49:25	http: validate server's authentication types Ensure that the server supports the particular credential type that we're specifying. Previously we considered credential types as an input to an auth mechanism - since the HTTP transport only supported default credentials (via negotiate) and username/password credentials (via basic), this worked. However, if we are to add another mechanism that uses username/password credentials, we'll need to be careful to identify the types that are accepted.
5ad99210	2019-03-07T16:43:45	http: consume body on proxy auth failure We must always consume the full parser body if we're going to keep-alive. So in the authentication failure case, continue advancing the http message parser until it's complete, then we can retry the connection. Not doing so would mean that we have to tear the connection down and start over. Advancing through fully (even though we don't use the data) will ensure that we can retry a connection with keep-alive.
75b20458	2019-03-07T16:34:55	http: always consume body on auth failure When we get an authentication failure, we must consume the entire body of the response. If we only read half of the body (on the assumption that we can ignore the rest) then we will never complete the parsing of the message. This means that we will never set the complete flag, and our replay must actually tear down the connection and try again. This is particularly problematic for stateful authentication mechanisms (SPNEGO, NTLM) that require that we keep the connection alive. Note that the prior code is only a problem when the 401 that we are parsing is too large to be read in a single chunked read from the http parser. But now we will continue to invoke the http parser until we've got a complete message in the authentication failed scenario. Note that we need not do anything with the message, so when we get an authentication failed, we'll stop adding data to our buffer, we'll simply loop in the parser and let it advance its internal state.

10e8fe55	2019-03-21T13:55:54	transports: add an `is_complete` function for auth Some authentication mechanisms (like HTTP Basic and Digest) have a one-step mechanism to create credentials, but there are more complex mechanisms like NTLM and Negotiate that require challenge/response after negotiation, requiring several round-trips. Add an `is_complete` function to know when they have round-tripped enough to be a single authentication and should now either have succeeded or failed to authenticate.
9050c69c	2019-03-09T17:24:16	http: examine keepalive status at message end We cannot examine the keep-alive status of the http parser in `http_connect`; it's too late and the critical information about whether keep-alive is supported has been destroyed. Per the documentation for `http_should_keep_alive`: > If http_should_keep_alive() in the on_headers_complete or > on_message_complete callback returns 0, then this should be > the last message on the connection. Query then and set the state.

d81e7866	2019-06-06T14:11:44	ignore: handle escaped trailing whitespace The gitignore's pattern format specifies that "Trailing spaces are ignored unless they are quoted with backslash ("\")". We do not honor this currently and will treat a pattern "foo\ " as if it was "foo\" only and a pattern "foo\ \ " as "foo\ \". Fix our code to handle those special cases and add tests to avoid regressions.
b6967c39	2019-06-06T14:02:17	attr_file: refactor stripping of trailing spaces The stripping of trailing spaces currently happens as part of `git_attr_fnmatch__parse`. As we aren't currently parsing trailing whitespaces correct in case they're escaped, we'll have to change that code, though. To make actual behavioural change easier to review, refactor the code up-front by pulling it out into its own function that is expected to retain the exact same functionality as before. Like this, the fix will be trivial to apply.

add17435	2019-05-24T15:24:26	cache: fix cache eviction using deallocated key When evicting cache entries, we first retrieve the object that is to be evicted, delete the object and then finally delete the key from the cache. In case where the cache eviction caused us to free the cached object, though, its key will point to invalid memory now when trying to remove it from the cache map. On my system, this causes us to not properly remove the key from the map, as its memory has been overwritten already and thus the key lookup it will fail and we cannot delete it. Fix this by only decrementing the refcount of the evictee after we have removed it from our cache map. Add a test that caused a segfault previous to that change.

Pass the current position of the line being parsed to the subsection parser, so that it can validate that subsequent characters are additional whitespace or a single quote. Previously we would begin parsing after the section name, looking for the first quotation mark. This allows invalid characters to embed themselves between the end of the section name and the first quotation mark, eg `[section foo "subsection"]`, which is illegal.

attr_file: convert to use `wildmatch` Upstream git has converted to use `wildmatch` instead of `fnmatch`. Convert our gitattributes logic to use `wildmatch` as the last user of `fnmatch`. Please, don't expect I know what I'm doing here: the fnmatch parser is one of the most fun things to play around with as it has a sh*tload of weird cases. In all honesty, I'm simply relying on our tests that are by now rather comprehensive in that area. The conversion actually fixes compatibility with how git.git parser "**" patterns when the given path does not contain any directory separators. Previously, a pattern "**.foo" erroneously wouldn't match a file "x.foo", while git.git would match. Remove the new-unused LEADINGDIR/NOLEADINGDIR flags for `git_attr_fnmatch`.

config_file: use `wildmatch` to evaluate conditionals We currently use `p_fnmatch` to compute whether a given "gitdir:" or "gitdir/i:" conditional matches the current configuration file path. As git.git has moved to use `wildmatch` instead of `p_fnmatch` throughout its complete codebase, we evaluate conditionals inconsistently with git.git in some special cases. Convert `p_fnmatch` to use `wildmatch`. The `FNM_LEADINGDIR` flag cannot be translated to `wildmatch`, but in fact git.git doesn't use it here either. And in fact, dropping it while we go increases compatibility with git.git.

Fix this issue by stripping the trailing '/' previous to matching. Add various tests to ensure we get this right.

To keep our own regex-matching in line with what git does, convert all trivial instances of `fnmatch` usage to use `wildcard`, instead. Trivial usage is defined to be use of `fnmatch` with either no flags or flags that have a 1:1 equivalent in wildmatch (PATHNAME, IGNORECASE).

We haven't followed suit, and thus have developed some incompatibilities in how we match regular expressions.

posix: remove `p_fallocate` abstraction By now, we have repeatedly failed to provide a nice cross-platform implementation of `p_fallocate`. Recent tries to do that escalated quite fast to a set of different CMake checks, implementations, fallbacks, etc., which started to look real awkward to maintain. In fact, `p_fallocate` had only been introduced in commit 4e3949b73 (tests: test that largefiles can be read through the tree API, 2019-01-30) to support a test with large files, but given the maintenance costs it just seems not to be worht it. As we have removed the sole user of `p_fallocate` in the previous commit, let's drop it altogether.

cmake: Modulize our TLS & hash detection The interactions between `USE_HTTPS` and `SHA1_BACKEND` have been streamlined. Previously we would have accepted not quite working configurations (like, `-DUSE_HTTPS=OFF -DSHA1_BACKEND=OpenSSL`) and, as the OpenSSL detection only ran with `USE_HTTPS`, the link would fail. The detection was moved to a new `USE_SHA1`, modeled after `USE_HTTPS`, which takes the values "CollisionDetection/Backend/Generic", to better match how the "hashing backend" is selected, the default (ON) being "CollisionDetection". Note that, as `SHA1_BACKEND` is still used internally, you might need to check what customization you're using it for.

apply: add an options struct initializer

0b5ba0d7

2019-06-06T16:36:23

Rename opt init functions to `options_init` In libgit2 nomenclature, when we need to verb a direct object, we name a function `git_directobject_verb`. Thus, if we need to init an options structure named `git_foo_options`, then the name of the function that does that should be `git_foo_options_init`. The previous names of `git_foo_init_options` is close - it _sounds_ as if it's initializing the options of a `foo`, but in fact `git_foo_options` is its own noun that should be respected. Deprecate the old names; they'll now call directly to the new ones.

attr_file: remove invalid TODO comment In our attributes pattern parsing code, we have a comment that states we might have to convert '\' characters to '/' to have proper POSIX paths. But in fact, '\' characters are valid inside the string and act as escape mechanism for various characters, which is why we never want to convert those to POSIX directory separators. Furthermore, gitignore patterns are specified to only treat '/' as directory separators. Remove the comment to avoid future confusion.

attr_file: account for escaped escapes when searching trailing space When determining the trailing space length, we need to honor whether spaces are escaped or not. Currently, we do not check whether the escape itself is escaped, though, which might generate an off-by-one in that case as we will simply treat the space as escaped. Fix this by checking whether the backslashes preceding the space are themselves escaped.

attr_file: fix unescaping of escapes required for fnmatch When parsing attribute patterns, we will eventually unescape the parsed pattern. This is required because we require custom escapes for whitespace characters, as normally they are used to terminate the current pattern. Thing is, we don't only unescape those whitespace characters, but in fact all escaped sequences. So for example if the pattern was "\*", we unescape that to "*". As this is directly passed to fnmatch(3) later, fnmatch would treat it as a simple glob matching all files where it should instead only match a file with name "*". Fix the issue by unescaping spaces, only. Add a bunch of tests to exercise escape parsing.

2019-06-07T09:17:23

attr_file: properly handle escaped '\' when searching non-escaped spaces When parsing attributes, we need to search for the first unescaped whitespace character to determine where the pattern is to be cut off. The scan fails to account for the case where the escaping '\' character is itself escaped, though, and thus we would not recognize the cut-off point in patterns like "\\ ". Refactor the scanning loop to remember whether the last character was an escape character. If it was and the next character is a '\', too, then we will reset to non-escaped mode again. Thus, we now handle escaped whitespaces as well as escaped wildcards correctly.

path: only treat paths starting with '\' as absolute on Win32 Windows-based systems treat paths starting with '\' as absolute, either referring to the current drive's root (e.g. "\foo" might refer to "C:\foo") or to a network path (e.g. "\\host\foo"). On the other hand, (most?) systems that are not based on Win32 accept backslashes as valid characters that may be part of the filename, and thus we cannot treat them to identify absolute paths. Change the logic to only paths starting with '\' as absolute on the Win32 platform. Add tests to avoid regressions and document behaviour.

winhttp: support default credentials for proxies We did not properly support default credentials for proxies, only for destination servers. Refactor the credential handling to support sending either username/password _or_ default credentials to either the proxy or the destination server. This actually shares the authentication logic between proxy servers and destination servers. Due to copy/pasta drift over time, they had diverged. Now they share a common logic which is: first, use credentials specified in the URL (if there were any), treating empty username and password (ie, "http://:@foo.com/") as default credentials, for compatibility with git. Next, call the credential callbacks. Finally, fallback to WinHTTP compatibility layers using built-in authentication like we always have. Allowing default credentials for proxies requires moving the security level downgrade into the credential setting routines themselves. We will update our security level to "high" by default which means that we will never send default credentials without prompting. (A lower setting, like the WinHTTP default of "medium" would allow WinHTTP to handle credentials for us, despite what a user may have requested with their structures.) Now we start with "high" and downgrade to "low" only after a user has explicitly requested default credentials.

http: maintain authentication across connections For request-based authentication mechanisms (Basic, Digest) we should keep the authentication context alive across socket connections, since the authentication headers must be transmitted with every request. However, we should continue to remove authentication contexts for mechanisms with connection affinity (NTLM, Negotiate) since we need to reauthenticate for every socket connection.

ce72ae95

2019-03-22T10:53:30

http: simplify authentication mechanisms Hold an individual authentication context instead of trying to maintain all the contexts; we can select the preferred context during the initial negotiation. Subsequent authentication steps will re-use the chosen authentication (until such time as it's rejected) instead of trying to manage multiple contexts when all but one will never be used (since we can only authenticate with a single mechanism at a time.) Also, when we're given a 401 or 407 in the middle of challenge/response handling, short-circuit immediately without incrementing the retry count. The multi-step authentication is expected, and not a "retry" and should not be penalized as such. This means that we don't need to keep the contexts around and ensures that we do not unnecessarily fail for too many retries when we have challenge/response auth on a proxy and a server and potentially redirects in play as well.

http: don't reset replay count after connection A "connection" to a server is transient, and we may reconnect to a server in the midst of authentication failures (if the remote indicates that we should, via `Connection: close`) or in a redirect.

http: validate server's authentication types Ensure that the server supports the particular credential type that we're specifying. Previously we considered credential types as an input to an auth mechanism - since the HTTP transport only supported default credentials (via negotiate) and username/password credentials (via basic), this worked. However, if we are to add another mechanism that uses username/password credentials, we'll need to be careful to identify the types that are accepted.

http: consume body on proxy auth failure We must always consume the full parser body if we're going to keep-alive. So in the authentication failure case, continue advancing the http message parser until it's complete, then we can retry the connection. Not doing so would mean that we have to tear the connection down and start over. Advancing through fully (even though we don't use the data) will ensure that we can retry a connection with keep-alive.

http: always consume body on auth failure When we get an authentication failure, we must consume the entire body of the response. If we only read half of the body (on the assumption that we can ignore the rest) then we will never complete the parsing of the message. This means that we will never set the complete flag, and our replay must actually tear down the connection and try again. This is particularly problematic for stateful authentication mechanisms (SPNEGO, NTLM) that require that we keep the connection alive. Note that the prior code is only a problem when the 401 that we are parsing is too large to be read in a single chunked read from the http parser. But now we will continue to invoke the http parser until we've got a complete message in the authentication failed scenario. Note that we need not do anything with the message, so when we get an authentication failed, we'll stop adding data to our buffer, we'll simply loop in the parser and let it advance its internal state.

transports: add an `is_complete` function for auth Some authentication mechanisms (like HTTP Basic and Digest) have a one-step mechanism to create credentials, but there are more complex mechanisms like NTLM and Negotiate that require challenge/response after negotiation, requiring several round-trips. Add an `is_complete` function to know when they have round-tripped enough to be a single authentication and should now either have succeeded or failed to authenticate.

http: examine keepalive status at message end We cannot examine the keep-alive status of the http parser in `http_connect`; it's too late and the critical information about whether keep-alive is supported has been destroyed. Per the documentation for `http_should_keep_alive`: > If http_should_keep_alive() in the on_headers_complete or > on_message_complete callback returns 0, then this should be > the last message on the connection. Query then and set the state.

ignore: handle escaped trailing whitespace The gitignore's pattern format specifies that "Trailing spaces are ignored unless they are quoted with backslash ("\")". We do not honor this currently and will treat a pattern "foo\ " as if it was "foo\" only and a pattern "foo\ \ " as "foo\ \". Fix our code to handle those special cases and add tests to avoid regressions.

attr_file: refactor stripping of trailing spaces The stripping of trailing spaces currently happens as part of `git_attr_fnmatch__parse`. As we aren't currently parsing trailing whitespaces correct in case they're escaped, we'll have to change that code, though. To make actual behavioural change easier to review, refactor the code up-front by pulling it out into its own function that is expected to retain the exact same functionality as before. Like this, the fix will be trivial to apply.

cache: fix cache eviction using deallocated key When evicting cache entries, we first retrieve the object that is to be evicted, delete the object and then finally delete the key from the cache. In case where the cache eviction caused us to free the cached object, though, its key will point to invalid memory now when trying to remove it from the cache map. On my system, this causes us to not properly remove the key from the map, as its memory has been overwritten already and thus the key lookup it will fail and we cannot delete it. Fix this by only decrementing the refcount of the evictee after we have removed it from our cache map. Add a test that caused a segfault previous to that change.

config: rename subsection header parser func The `parse_section_header_ext` name suggests that it as an extended function for parsing the section header. It is not. Rename it to `parse_subsection_header` to better reflect its true mission.

config: validate quoted section value When we reach a whitespace after a section name, we assume that what will follow will be a quoted subsection name. Pass the current position of the line being parsed to the subsection parser, so that it can validate that subsequent characters are additional whitespace or a single quote. Previously we would begin parsing after the section name, looking for the first quotation mark. This allows invalid characters to embed themselves between the end of the section name and the first quotation mark, eg `[section foo "subsection"]`, which is illegal.
