Patrick Steinhardt 9994cd3f 2018-06-25T11:56:52 treewide: remove use of C++ style comments C++ style comment ("//") are not specified by the ISO C90 standard and thus do not conform to it. While libgit2 aims to conform to C90, we did not enforce it until now, which is why quite a lot of these non-conforming comments have snuck into our codebase. Do a tree-wide conversion of all C++ style comments to the supported C style comments to allow us enforcing strict C90 compliance in a later commit.
Patrick Steinhardt ecf4f33a 2018-02-08T11:14:48 Convert usage of `git_buf_free` to new `git_buf_dispose`
Patrick Steinhardt 6a15f657 2018-02-09T13:02:26 config_file: iterate over keys in the order they were added Currently, all configuration entries were only held in a string map, making iteration order mostly based on the hash of each entry's key. Now that we have extended the `diskfile_entries` structure by a list of config entries, we can effectively iterate through entries in the order they were added, though.
Patrick Steinhardt 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.
Patrick Steinhardt 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.
Carlos Martín Nieto 42627933 2017-11-04T18:03:26 Merge remote-tracking branch 'upstream/master' into pks/conditional-includes
Carlos Martín Nieto c44b9170 2017-10-31T09:52:33 tests: resolve the real path for the sandbox in includeIf tests We put our repository in the temporary directory which makes macOS map the path into a virtual path. `realpath(3)` can resolve it and we do so during repository opening, but that makes its path have a different prefix from the sandbox path clar thinks we have. Resolve the sandbox path before putting it into the test config files so the paths match as expected.
Carlos Martín Nieto bb8bc4b8 2017-10-30T06:21:55 config: add failing test for preserving case when writing keys While most parts of a configuration key are case-insensitive, we should still be case-preserving and write down whatever string the caller provided.
Patrick Steinhardt 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.
Patrick Steinhardt 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.
Patrick Steinhardt 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`.
Patrick Steinhardt 1b329089 2017-05-31T22:27:19 config_file: refuse modifying included variables Modifying variables pulled in by an included file currently succeeds, but it doesn't actually do what one would expect, as refreshing the configuration will cause the values to reappear. As we are currently not really able to support this use case, we will instead just return an error for deleting and setting variables which were included via an include.
Patrick Steinhardt 28c2cc3d 2017-05-31T16:41:44 config_file: move reader into `config_read` only Right now, we have multiple call sites which initialize a `reader` structure. As the structure is only actually used inside of `config_read`, we can instead just move the reader inside of the `config_read` function. Instead, we can just pass in the configuration file into `config_read`, which eases code readability.
Patrick Steinhardt 83bcd3a1 2017-05-31T22:45:25 config_file: refresh all files if includes were modified Currently, we only re-parse the top-level configuration file when it has changed itself. This can cause problems when an include is changed, as we were not updating all values correctly. Instead of conditionally reparsing only refreshed files, the logic becomes much clearer and easier to follow if we always re-parse the top-level configuration file when either the file itself or one of its included configuration files has changed on disk. This commit implements this logic. Note that this might impact performance in some cases, as we need to re-read all configuration files whenever any of the included files changed. It could increase performance to just re-parse include files which have actually changed, but this would compromise maintainability of the code without much gain. The only case where we will gain anything is when we actually use includes and when only these includes are updated, which will probably be quite an unusual scenario to actually be worthwhile to optimize.
Patrick Steinhardt 6f7aab0c 2017-06-06T09:45:11 tests: config::include: use init and cleanup functions
Patrick Steinhardt 1f7af277 2017-07-05T11:52:47 tests: config: fix missing declaration causing error On systems where we pull in our distributed version of the regex library, all tests in config::readonly fail. This error is actually quite interesting: the test suite is unable to find the declaration of `git_path_exists` and assumes it has a signature of `int git_path_exists(const char *)`. But actually, it has a `bool` return value. Due to this confusion, some wrong conversion is done by the compiler and the `cl_assert(!git_path_exists("file"))` checks erroneously fail, even when the function does in fact return the correct value. The error is actually introduced by 56893bb9a (cmake: consistently use TARGET_INCLUDE_DIRECTORIES if available, 2017-06-28), unfortunately introduced by myself. Due to the delayed addition of include directories, we will now find the "config.h" header inside of the "deps/regex" directory instead of inside the "src/" directory, where it should be. As such, we are missing definitions for the `git_config_file__ondisk` and `git_path_exists` symbols. The correct fix here would be to fix the order in which include search directories are added. But due to the current restructuring of CMakeBuild.txt, I'm refraining from doing so and delay the proper fix a bit. Instead, we paper over the issue by explicitly including "path.h" to fix its prototype. This ignores the issue that `git_config_file__ondisk` is undeclared, as its signature is correctly identified by the compiler.

Edward Thomson 76e1a679 2016-03-28T08:56:13 config::write::repeated: init our buffer
Carlos Martín Nieto 3e95bd36 2016-03-04T14:51:16 config: show we write a spurious duplicated section header We should notice that we are in the correct section to add. This is a cosmetic bug, since replacing any of these settings does work.
Carlos Martín Nieto 6f09911c 2016-03-21T21:10:26 config: don't special-case multivars that don't exist yet This special-casing ignores that we might have a locked file, so the hashtable does not represent the contents of the file we want to write. This causes multivar writes to overwrite entries instead of add to them when under lock. There is no need for this as the normal code-path will write to the file just fine, so simply get rid of it.

Carlos Martín Nieto a2f96479 2015-10-29T20:31:25 config: add failing test for an external modification We currently use the timestamp in order to decide whether a config file has changed since we last read it. This scheme falls down if the file is written twice within the same second, as we fail to detect the file change after the first read in that second.
Carlos Martín Nieto 8c7c5fa5 2015-10-20T17:42:42 config: add a ProgramData level This is where portable git stores the global configuration which we can use to adhere to it even though git isn't quite installed on the system.
Linquize 08313c4b 2015-09-18T11:30:50 config: test that comments are left as with git
Edward Thomson ac2fba0e 2015-09-16T15:07:27 git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.
Arthur Schreiber 548cb334 2015-09-13T16:32:24 Don't free config in `git_transaction_commit`. The config is not owned by the transaction, so please don’t free it.
Carlos Martín Nieto 5340d63d 2015-07-12T12:50:23 config: perform unlocking via git_transaction This makes the API for commiting or discarding changes the same as for references.
Carlos Martín Nieto 36f784b5 2015-06-01T20:02:23 config: expose locking via the main API This lock/unlock pair allows for the cller to lock a configuration file to avoid concurrent operations. It also allows for a transactional approach to updating a configuration file. If multiple updates must be made atomically, they can be done while the config is locked.
Carlos Martín Nieto b1667039 2015-06-01T19:17:03 config: implement basic transactional support When a configuration file is locked, any updates made to it will be done to the in-memory copy of the file. This allows for multiple updates to happen while we hold the lock, preventing races during complex config-file manipulation.
Edward Thomson d6b7e404 2015-05-04T07:36:21 config: test all multivars are updated If a multivar exists within two sections (of the same name) then they should both be updated in a `set_multivar`. Ensure that this is the case.
Edward Thomson 0daf998d 2015-04-27T16:31:18 config: use wildcard in test instead of empty expr
Edward Thomson 63c0cc65 2015-04-27T16:29:00 config: cleanup some now-unused variables
Ryan Roden-Corrent 5a70df94 2015-04-21T15:57:20 Test setting config var under duplicate header. Add a test that exposes a bug in config_write. It is valid to have multiple separate headers for the same config section, but config_write will exit after finding the first matching section in certain situations. This test proves that config_write will duplicate a variable that already exists instead of overwriting it if the variable is defined under a duplicate section header.
Edward Thomson bf99390e 2015-04-23T16:54:36 config: examine whole file when writing Previously we would try to be clever when writing the configuration file and try to stop parsing (and simply copy the rest of the old file) when we either found the value we were trying to write, or when we left the section that value was in, the assumption being that there was no more work to do. Regrettably, you can have another section with the same name later in the file, and we must cope with that gracefully, thus we read the whole file in order to write a new file. Now, writing a file looks even more than reading. Pull the config parsing out into its own function that can be used by both reading and writing the configuration.
Edward Thomson f79c7322 2015-04-23T12:00:05 config: test overwriting cvar in multiple regions

Ryan Roden-Corrent a060cccc 2015-04-16T10:53:22 Unittest to validate config entry deletion bug. Add a unittest to validate bug #3043, where a duplicate empty config header could cause deletion of a config entry to fail silently. The bug is currently unresolved and this test will fail.
Edward Thomson e009a705 2015-04-20T00:22:20 config_file: comment char can be invalid escape Don't assume that comment chars are comment chars, they may be (an attempt to be escaped). If so, \; is not a valid escape sequence, complain.
Edward Thomson 7f2e61f3 2015-04-19T23:55:02 config_file: parse multilines generously Combine unquoting and multiline detection to avoid ambiguity when parsing.
Patrick Steinhardt 129022ee 2015-04-10T09:36:38 Fix checking of return value for regcomp. The regcomp function returns a non-zero value if compilation of a regular expression fails. In most places we only check for negative values, but positive values indicate an error, as well. Fix this tree-wide, fixing a segmentation fault when calling git_config_iterator_glob_new with an invalid regexp.
Carlos Martín Nieto fe21d708 2015-03-04T00:29:37 Plug a few leaks
Carlos Martín Nieto 9a97f49e 2014-12-21T15:31:03 config: borrow refcounted references This changes the get_entry() method to return a refcounted version of the config entry, which you have to free when you're done. This allows us to avoid freeing the memory in which the entry is stored on a refresh, which may happen at any time for a live config. For this reason, get_string() has been forbidden on live configs and a new function get_string_buf() has been added, which stores the string in a git_buf which the user then owns. The functions which parse the string value takea advantage of the borrowing to parse safely and then release the entry.
Yury G. Kudryashov 3ea78f24 2015-02-09T19:40:22 Add test for include.path inside included config It fails at least on my computer, though it may depend on some unpredictable factors (say, will realloc() extend the memory segment in place, or it will allocate new memory).

Edward Thomson 34100846 2014-11-26T16:24:37 tests: use p_ instead of posix func directly
John Fultz ebc13b2b 2014-11-02T19:16:49 Clean up issues include.path issues found during code review. * Error-handling is cleaned up to only let a file-not-found error through, not other sorts of errors. And when a file-not-found error happens, we clean up the error. * Test now checks that file-not-found introduces no error. And other minor cleanups.
John Fultz 727ae380 2014-11-01T11:21:45 Make config reading continue after hitting a missing include file. For example, if you have [include] path = foo and foo didn't exist, git_config_open_ondisk() would just give up on the rest of the file. Now it ignores the unresolved include without error and continues reading the rest of the file.

Carlos Martín Nieto 55cb4999 2014-10-23T19:05:02 config: remove the refresh function and backend field We have been refreshing on read and write for a while now, so git_config_refresh() is at best a no-op, and might just end up wasting cycles.

Linquize a447a7e4 2014-10-04T23:28:40 config: Add test cases that have trailing spaces before comment chars
Carlos Martín Nieto 9dac1f95 2014-08-09T10:56:50 config: a multiline var can start immediately In the check for multiline, we traverse the backslashes from the end backwards and int the end assert that we haven't gone past the beginning of the line. We make sure of this in the loop condition, but we also check in the return value. However, for certain configurations, a line in a multiline variable might be empty to aid formatting. In that case, 'end' == 'start', since we ended up looking at the first char which made it a multiline. There is no need for the (end > start) check in the return, since the loop guarantees we won't go further back than the first char in the line, and we do accept the first char to be the final backslash. This fixes #2483.

Russell Belfer 8487e237 2014-05-15T10:56:28 Better search path sandboxing There are a number of tests that modify the global or system search paths during the tests. This adds a helper function to make it easier to restore those paths and makes sure that they are getting restored in a manner that preserves test isolation.
Russell Belfer d2c4d1c6 2014-05-12T10:04:52 Merge pull request #2188 from libgit2/cmn/config-snapshot Configuration snapshotting
Russell Belfer 0f603132 2014-05-01T14:47:33 Improve handling of fake home directory There are a few tests that set up a fake home directory and a fake GLOBAL search path so that we can test things in global ignore or attribute or config files. This cleans up that code to work more robustly even if there is a test failure. This also fixes some valgrind warnings where scanning search paths for separators could end up doing a little bit of sketchy data access when coming to the end of search list.
nulltoken 48ebea66 2013-01-07T00:20:13 tests: Introduce count_config_entries_match() helper
Carlos Martín Nieto 8c1f4ab4 2014-04-09T12:26:53 config: refresh on delete When we delete an entry, we also want to refresh the configuration to catch any changes that happened externally. This allows us to simplify the logic, as we no longer need to delete these variables internally. The whole state will be refreshed and the deleted entries won't be there.
Carlos Martín Nieto 523032cd 2014-03-31T09:58:44 config: refresh before reading a value With the isolation of complex reads, we can now try to refresh the on-disk file before reading a value from it. This changes the semantics a bit, as before we could be sure that a string we got from the configuration was valid until we wrote or refreshed. This is no longer the case, as a read can also invalidate the pointer.
Carlos Martín Nieto eaf37034 2014-03-31T08:53:56 config: refresh the values on write When writing out, parse the resulting file instead of adding or replacing the value locally. This has the effect of reading external changes as well.
Carlos Martín Nieto 55ebd7d3 2014-03-13T17:11:34 config: implement config snapshotting In order to have consistent views of the config files for remotes, submodules et al. and a configuration that represents what is currently stored on-disk, we need a way to provide a view of the configuration that does not change. The goal here is to provide the snapshotting part by creating a read-only copy of the state of the configuration at a particular point in time, which does not change when a repository's main config changes.
Carlos Martín Nieto 36913b8c 2014-03-06T15:11:11 config: document current write behaviour in a test On set, we set/add the value written to the config's internal values, but we do not refresh old values. Document this in a test in preparation for the refresh changes.
Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
Russell Belfer 96869a4e 2013-12-03T16:45:39 Improve GIT_EUSER handling This adds giterr_user_cancel to return GIT_EUSER and clear any error message that is sitting around. As a result of using that in places, we need to be more thorough with capturing errors that happen inside a callback when used internally. To help with that, this also adds giterr_capture and giterr_restore so that when we internally use a foreach-type function that clears errors and converts them to GIT_EUSER, it is easier to restore not just the return value, but the actual error message text.
