2eea5f1c	2018-02-08T10:27:31	config_parse: fix reading files with BOM The function `skip_bom` is being used to detect and skip BOM marks previously to parsing a configuration file. To do so, it simply uses `git_buf_text_detect_bom`. But since the refactoring to use the parser interface in commit 9e66590bd (config_parse: use common parser interface, 2017-07-21), the BOM detection was actually broken. The issue stems from a misunderstanding of `git_buf_text_detect_bom`. It was assumed that its third parameter limits the length of the character sequence that is to be analyzed, while in fact it was an offset at which we want to detect the BOM. Fix the parameter to be `0` instead of the buffer length, as we always want to check the beginning of the configuration file.
848153f3	2018-02-08T10:02:29	config_parse: handle empty lines with CRLF Currently, the configuration parser will fail reading empty lines with just an CRLF-style line ending. Special-case the '\r' character in order to handle it the same as Unix-style line endings. Add tests to spot this regression in the future.

b924df1e	2018-01-21T18:05:45	merge: reverse merge bases for recursive merge When the commits being merged have multiple merge bases, reverse the order when creating the virtual merge base. This is for compatibility with git's merge-recursive algorithm, and ensures that we build identical trees. Git does this to try to use older merge bases first. Per 8918b0c: > It seems to be the only sane way to do it: when a two-head merge is > done, and the merge-base and one of the two branches agree, the > merge assumes that the other branch has something new. > > If we start creating virtual commits from newer merge-bases, and go > back to older merge-bases, and then merge with newer commits again, > chances are that a patch is lost, _because_ the merge-base and the > head agree on it. Unlikely, yes, but it happened to me.

275f103d	2018-01-12T08:59:40	odb: reject reading and writing null OIDs The null OID (hash with all zeroes) indicates a missing object in upstream git and is thus not a valid object ID. Add defensive measurements to avoid writing such a hash to the object database in the very unlikely case where some data results in the null OID. Furthermore, add shortcuts when reading the null OID from the ODB to avoid ever returning an object when a faulty repository may contain the null OID.
c0487bde	2018-01-12T08:23:43	tree: reject writing null-OID entries to a tree In commit a96d3cc3f (cache-tree: reject entries with null sha1, 2017-04-21), the git.git project has changed its stance on null OIDs in tree objects. Previously, null OIDs were accepted in tree entries to help tools repair broken history. This resulted in some problems though in that many code paths mistakenly passed null OIDs to be added to a tree, which was not properly detected. Align our own code base according to the upstream change and reject writing tree entries early when the OID is all-zero.
9af7fbc3	2018-01-21T14:00:50	status::renames: write NFD instead of NFC filename Update the status::renames test to create an NFD format filename in the core.precomposedunicode tests. Previously, we would create an NFC format filename. This was to take advantage of HFS+ filesystems, which always use canonically decomposed formats, and would actually write the filename to disk as an NFD filename. So previously, we could create an NFC filename, but read it normally as an NFD filename. But APFS formats do not force canonically decomposed formats for filenames, so creating an NFC filename does not get converted to NFD. Instead, the filename will be written in NFC format. Our test, therefore, does not work - when we write an NFC filename, it will _remain_ NFC. Update the test to write NFD always. This will ensure that the file will actually be canonically decomposed on all platforms: HFS+, which forces NFD, and APFS, which does not. Thus, our test will continue to ensure that an NFD filename is canonically precomposed on all filesystems.
2a8841ae	2018-01-21T12:28:13	merge: test CR/LF conflicts for CR/LF files Ensure that when the files being merged have CR/LF line endings that the conflict markers produced in the conflict file also have CR/LF line endings.
185b0d08	2018-01-20T19:41:28	merge: recursive uses larger conflict markers Git uses longer conflict markers in the recursive merge base - two more than the default (thus, 9 character long conflict markers). This allows users to tell the difference between the recursive merge conflicts and conflicts between the ours and theirs branches. This was introduced in git d694a17986a28bbc19e2a6c32404ca24572e400f. Update our tests to expect this as well.

This is not necessary, though, as the cleanup function executed after each test already takes care of cleaning up after them. Remove the code to avoid needless code duplication.

5874e151	2017-11-20T13:26:33	tests: create new test target for all SSH-based tests Some tests shall be run against our own SSH server we spin up in Travis. As those need to be run separate from our previous tests which run against git-daemon, we have to do this in a separate step. Instead of bundling all that knowledge in the CI script, move it into the test build instructions by creating a new test target.
54a1bf05	2017-06-07T13:06:53	tests: online::clone: inline creds-test with nonexistent URL Right now, we test our credential callback code twice, once via SSH on localhost and once via a non-existent GitHub repository. While the first URL makes sense to be configurable, it does not make sense to hard-code the non-existing repository, which requires us to call tests multiple times. Instead, we can just inline the URL into another set of tests.
fea60920	2017-06-07T12:48:48	tests: online::clone: construct credential-URL from environment We support two types of passing credentials to the proxy, either via the URL or explicitly by specifying user and password. We test these types by modifying the proxy URL and executing the tests twice, which is in fact unnecessary and requires us to maintain the list of environment variables and test executions across multiple CI infrastructures. To fix the situation, we can just always pass the host, port, user and password to the tests. The tests can then assemble the complete URL either with or without included credentials, allowing us to test both cases in-process.
543ec149	2017-06-07T11:06:01	tests: perf: build but exclude performance tests by default Our performance tests (or to be more concrete, our single performance test) are not built by default, as they are always #ifdef'd out. While it is true that we don't want to run performance tests by default, not compiling them at all may cause code rot and is thus an unfavorable approach to handle this. We can easily improve this situation: this commit removes the #ifdef, causing the code to always be compiled. Furthermore, we add `-xperf` to the default command line parameters of `generate.py`, thus causing the tests to be excluded by default. Due to this approach, we are now able to execute the performance tests by passing `-sperf` to `libgit2_clar`. Unfortunately, we cannot execute the performance tests on Travis or AppVeyor as they rely on history being available for the libgit2 repository. As both do a shallow clone only, though, this is not given.
b8c14499	2017-06-07T11:00:26	tests: iterator::workdir: fix reference count in stale test The test `iterator::workdir::filesystem_gunk` is usually not executed, as it is guarded by the environment variable "GITTEST_INVASIVE_SPEED" due to its effects on speed. As such, it has become stale and does not account for new references which have meanwhile been added to the testrepo, causing it to fail. Fix this by raising the number of expected references to 15.
9aba7636	2017-06-07T10:59:31	tests: iterator_helpers: assert number of iterator items When the function `expect_iterator_items` surpasses the number of expected items, we simply break the loop. This causes us to trigger an assert later on which has message attached, which is annoying when trying to locate the root error cause. Instead, directly assert that the current count is still smaller or equal to the expected count inside of the loop.
72c28ab0	2017-06-07T10:59:03	tests: status::worktree: indicate skipped tests on Win32 Some function bodies of tests which are not applicable to the Win32 platform are completely #ifdef'd out instead of calling `cl_skip()`. This leaves us with no indication that these tests are not being executed at all and may thus cause decreased scrutiny when investigating skipped tests. Improve the situation by calling `cl_skip()` instead of just doing nothing.

c3514b0b	2017-12-23T14:59:07	Fix unpack double free If an element has been cached, but then the call to packfile_unpack_compressed() fails, the very next thing that happens is that its data is freed and then the element is not removed from the cache, which frees the data again. This change sets obj->data to NULL to avoid the double-free. It also stops trying to resolve deltas after two continuous failed rounds of resolution, and adds a test for this.

This is useful for examining if a non-null terminated character array is prefixed by a particular substring. Consolidate the various implementations of `git__prefixcmp` around a single core implementation and add some test cases to validate its behavior.

fa8cf14f	2017-12-16T21:49:45	Merge pull request #4447 from pks-t/pks/diff-file-contents-refcount-blob diff_file: properly refcount blobs when initializing file contents
2388a9e2	2017-12-15T10:47:01	diff_file: properly refcount blobs when initializing file contents When initializing a `git_diff_file_content` from a source whose data is derived from a blob, we simply assign the blob's pointer to the resulting struct without incrementing its refcount. Thus, the structure can only be used as long as the blob is kept alive by the caller. Fix the issue by using `git_blob_dup` instead of a direct assignment. This function will increment the refcount of the blob without allocating new memory, so it does exactly what we want. As `git_diff_file_content__unload` already frees the blob when `GIT_DIFF_FLAG__FREE_BLOB` is set, we don't need to add new code handling the free but only have to set that flag correctly.

f063dafb	2017-11-12T10:56:50	signature: distinguish +0000 and -0000 UTC offsets Git considers '-0000' a valid offset for signature lines. They need to be treated as _not_ equal to a '+0000' signature offset. Parsing a signature line stores the offset in a signed integer which does not distinguish between `+0` and `-0`. This patch adds an additional flag `sign` to the `git_time` in the `signature` object which is populated with the sign of the offset. In addition to exposing this information to the user, this information is also used to compare signatures. /cc @pks-t @ethomson
80226b5f	2017-09-22T13:39:05	patch_parse: allow parsing ambiguous patch headers The git patch format allows for having unquoted paths with whitespaces inside. This format becomes ambiguous to parse, e.g. in the following example: diff --git a/file b/with spaces.txt b/file b/with spaces.txt While we cannot parse this in a correct way, we can instead use the "---" and "+++" lines to retrieve the file names, as the path is not followed by anything here but spans the complete remaining line. Because of this, we can simply bail outwhen parsing the "diff --git" header here without an actual error and then proceed to just take the paths from the other headers.

4da74c83	2017-10-20T07:29:17	cmake: use project-relative binary and source directories Due to our split of CMake files into multiple modules, we had to replace some uses of the `${CMAKE_CURRENT_SOURCE_DIR}` and `${CMAKE_CURRENT_BINARY_DIR}` variables and replace them with `${CMAKE_SOURCE_DIR}` and `${CMAKE_BINARY_DIR}`. This enabled us to still be able to refer to top-level files when defining build instructions inside of a subdirectory. When replacing all variables, it was assumed that the absolute set of variables is always relative to the current project. But in fact, this is not the case, as these variables always point to the source and binary directory as given by the top-levl project. So the change actually broke the ability to include libgit2 directly as a subproject, as source files cannot be found anymore. Fix this by instead using project-specific source and binary directories with `${libgit2_SOURCE_DIR}` and `${libgit2_BINARY_DIR}`.
f7d837c8	2017-05-24T12:12:29	config_file: implement "gitdir/i" conditional Next to the "gitdir" conditional for including other configuration files, there's also a "gitdir/i" conditional. In contrast to the former one, path matching with "gitdir/i" is done case-insensitively. This commit implements the case-insensitive condition.
071b6c06	2017-05-24T11:13:36	config_file: implement conditional "gitdir" includes Upstream git.git has implemented the ability to include other configuration files based on conditions. Right now, this only includes the ability to include a file based on the gitdir-location of the repository the currently parsed configuration file belongs to. This commit implements handling these conditional includes for the case-sensitive "gitdir" condition.
529e873c	2017-05-23T11:51:00	config: pass repository when opening config files Our current configuration logic is completely oblivious of any repository, but only cares for actual file paths. Unfortunately, we are forced to break this assumption by the introduction of conditional includes, which are evaluated in the context of a repository. Right now, only one conditional exists with "gitdir:" -- it will only include the configuration if the current repository's git directory matches the value passed to "gitdir:". To support these conditionals, we have to break our API and make the repository available when opening a configuration file. This commit extends the `open` call of configuration backends to include another repository and adjusts existing code to have it available. This includes the user-visible functions `git_config_add_file_ondisk` and `git_config_add_backend`.

config_parse: fix reading files with BOM The function `skip_bom` is being used to detect and skip BOM marks previously to parsing a configuration file. To do so, it simply uses `git_buf_text_detect_bom`. But since the refactoring to use the parser interface in commit 9e66590bd (config_parse: use common parser interface, 2017-07-21), the BOM detection was actually broken. The issue stems from a misunderstanding of `git_buf_text_detect_bom`. It was assumed that its third parameter limits the length of the character sequence that is to be analyzed, while in fact it was an offset at which we want to detect the BOM. Fix the parameter to be `0` instead of the buffer length, as we always want to check the beginning of the configuration file.

merge: reverse merge bases for recursive merge When the commits being merged have multiple merge bases, reverse the order when creating the virtual merge base. This is for compatibility with git's merge-recursive algorithm, and ensures that we build identical trees. Git does this to try to use older merge bases first. Per 8918b0c: > It seems to be the only sane way to do it: when a two-head merge is > done, and the merge-base and one of the two branches agree, the > merge assumes that the other branch has something new. > > If we start creating virtual commits from newer merge-bases, and go > back to older merge-bases, and then merge with newer commits again, > chances are that a patch is lost, _because_ the merge-base and the > head agree on it. Unlikely, yes, but it happened to me.

odb: reject reading and writing null OIDs The null OID (hash with all zeroes) indicates a missing object in upstream git and is thus not a valid object ID. Add defensive measurements to avoid writing such a hash to the object database in the very unlikely case where some data results in the null OID. Furthermore, add shortcuts when reading the null OID from the ODB to avoid ever returning an object when a faulty repository may contain the null OID.

tree: reject writing null-OID entries to a tree In commit a96d3cc3f (cache-tree: reject entries with null sha1, 2017-04-21), the git.git project has changed its stance on null OIDs in tree objects. Previously, null OIDs were accepted in tree entries to help tools repair broken history. This resulted in some problems though in that many code paths mistakenly passed null OIDs to be added to a tree, which was not properly detected. Align our own code base according to the upstream change and reject writing tree entries early when the OID is all-zero.

status::renames: write NFD instead of NFC filename Update the status::renames test to create an NFD format filename in the core.precomposedunicode tests. Previously, we would create an NFC format filename. This was to take advantage of HFS+ filesystems, which always use canonically decomposed formats, and would actually write the filename to disk as an NFD filename. So previously, we could create an NFC filename, but read it normally as an NFD filename. But APFS formats do not force canonically decomposed formats for filenames, so creating an NFC filename does not get converted to NFD. Instead, the filename will be written in NFC format. Our test, therefore, does not work - when we write an NFC filename, it will _remain_ NFC. Update the test to write NFD always. This will ensure that the file will actually be canonically decomposed on all platforms: HFS+, which forces NFD, and APFS, which does not. Thus, our test will continue to ensure that an NFD filename is canonically precomposed on all filesystems.

Update our tests to expect this as well.

tests: online::clone: inline creds-test with nonexistent URL Right now, we test our credential callback code twice, once via SSH on localhost and once via a non-existent GitHub repository. While the first URL makes sense to be configurable, it does not make sense to hard-code the non-existing repository, which requires us to call tests multiple times. Instead, we can just inline the URL into another set of tests.

tests: online::clone: construct credential-URL from environment We support two types of passing credentials to the proxy, either via the URL or explicitly by specifying user and password. We test these types by modifying the proxy URL and executing the tests twice, which is in fact unnecessary and requires us to maintain the list of environment variables and test executions across multiple CI infrastructures. To fix the situation, we can just always pass the host, port, user and password to the tests. The tests can then assemble the complete URL either with or without included credentials, allowing us to test both cases in-process.

tests: perf: build but exclude performance tests by default Our performance tests (or to be more concrete, our single performance test) are not built by default, as they are always #ifdef'd out. While it is true that we don't want to run performance tests by default, not compiling them at all may cause code rot and is thus an unfavorable approach to handle this. We can easily improve this situation: this commit removes the #ifdef, causing the code to always be compiled. Furthermore, we add `-xperf` to the default command line parameters of `generate.py`, thus causing the tests to be excluded by default. Due to this approach, we are now able to execute the performance tests by passing `-sperf` to `libgit2_clar`. Unfortunately, we cannot execute the performance tests on Travis or AppVeyor as they rely on history being available for the libgit2 repository. As both do a shallow clone only, though, this is not given.

Instead, directly assert that the current count is still smaller or equal to the expected count inside of the loop.

tests: status::worktree: indicate skipped tests on Win32 Some function bodies of tests which are not applicable to the Win32 platform are completely #ifdef'd out instead of calling `cl_skip()`. This leaves us with no indication that these tests are not being executed at all and may thus cause decreased scrutiny when investigating skipped tests. Improve the situation by calling `cl_skip()` instead of just doing nothing.

2388a9e2

2017-12-15T10:47:01

diff_file: properly refcount blobs when initializing file contents When initializing a `git_diff_file_content` from a source whose data is derived from a blob, we simply assign the blob's pointer to the resulting struct without incrementing its refcount. Thus, the structure can only be used as long as the blob is kept alive by the caller. Fix the issue by using `git_blob_dup` instead of a direct assignment. This function will increment the refcount of the blob without allocating new memory, so it does exactly what we want. As `git_diff_file_content__unload` already frees the blob when `GIT_DIFF_FLAG__FREE_BLOB` is set, we don't need to add new code handling the free but only have to set that flag correctly.

signature: distinguish +0000 and -0000 UTC offsets Git considers '-0000' a valid offset for signature lines. They need to be treated as _not_ equal to a '+0000' signature offset. Parsing a signature line stores the offset in a signed integer which does not distinguish between `+0` and `-0`. This patch adds an additional flag `sign` to the `git_time` in the `signature` object which is populated with the sign of the offset. In addition to exposing this information to the user, this information is also used to compare signatures. /cc @pks-t @ethomson

patch_parse: allow parsing ambiguous patch headers The git patch format allows for having unquoted paths with whitespaces inside. This format becomes ambiguous to parse, e.g. in the following example: diff --git a/file b/with spaces.txt b/file b/with spaces.txt While we cannot parse this in a correct way, we can instead use the "---" and "+++" lines to retrieve the file names, as the path is not followed by anything here but spans the complete remaining line. Because of this, we can simply bail outwhen parsing the "diff --git" header here without an actual error and then proceed to just take the paths from the other headers.

This enabled us to still be able to refer to top-level files when defining build instructions inside of a subdirectory. When replacing all variables, it was assumed that the absolute set of variables is always relative to the current project. But in fact, this is not the case, as these variables always point to the source and binary directory as given by the top-levl project. So the change actually broke the ability to include libgit2 directly as a subproject, as source files cannot be found anymore. Fix this by instead using project-specific source and binary directories with `${libgit2_SOURCE_DIR}` and `${libgit2_BINARY_DIR}`.

config_file: implement "gitdir/i" conditional Next to the "gitdir" conditional for including other configuration files, there's also a "gitdir/i" conditional. In contrast to the former one, path matching with "gitdir/i" is done case-insensitively. This commit implements the case-insensitive condition.

config_file: implement conditional "gitdir" includes Upstream git.git has implemented the ability to include other configuration files based on conditions. Right now, this only includes the ability to include a file based on the gitdir-location of the repository the currently parsed configuration file belongs to. This commit implements handling these conditional includes for the case-sensitive "gitdir" condition.

config: pass repository when opening config files Our current configuration logic is completely oblivious of any repository, but only cares for actual file paths. Unfortunately, we are forced to break this assumption by the introduction of conditional includes, which are evaluated in the context of a repository. Right now, only one conditional exists with "gitdir:" -- it will only include the configuration if the current repository's git directory matches the value passed to "gitdir:". To support these conditionals, we have to break our API and make the repository available when opening a configuration file. This commit extends the `open` call of configuration backends to include another repository and adjusts existing code to have it available. This includes the user-visible functions `git_config_add_file_ondisk` and `git_config_add_backend`.

tests: checkout::tree: check that the status list catches mode changes While we verify that we have no mode changes after calling `git_checkout_tree`, we do not verify that the `p_chmod` calls actually resulted in a changed entry. While we should assume that this works due to separate tests for the status list, we should test for the change being listed to avoid programming errors in the test.

tests: checkout::tree: extract check for status entrycount There are multiple locations where we have the same code to check whether the count of status list entries of a repository matches an expected number. Extract that into a common function.
