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.

836447e5	2016-03-10T16:52:09	config_file: handle error when trying to lock strmap Accessing the current values map is handled through the `refcounder_strmap_take` function, which first acquires a mutex before accessing its values. While this assures everybody is trying to access the values with the mutex only we do not check if the locking actually succeeds. Fix the issue by checking if acquiring the lock succeeds and returning `NULL` if we encounter an error. Adjust callers.
e126bc95	2016-03-01T14:40:17	config_file: handle missing quotation marks in section header When parsing a section header we expect something along the format of '[section "subsection"]'. When a section is mal-formated and is entirely missing its quotation marks we catch this case by observing that `strchr(line, '"') - strrchr(line, '"') = NULL - NULL = 0` and error out. Unfortunately, the error message is misleading though, as we state that we are missing the closing quotation mark while we in fact miss both quotation marks. Improve the error message by explicitly checking if the first quotation mark could be found and, if not, stating that quotation marks are completely missing.
eb597799	2015-10-29T21:12:37	filebuf: use a checksum to detect file changes Instead of relying on the size and timestamp, which can hide changes performed in the same second, hash the file content's when we care about detecting changes.
cd677b8f	2015-09-18T12:28:05	config: buffer comments to match git's variable-adding When there is a comment at the end of a section, git keeps it there, while we write the new variable right at the end. Keep comments buffered and dump them when we're going to output a variable or section, or reach EOF. This puts us in line with the config files which git produces.
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.
3ce9e4d2	2015-06-01T08:45:15	config: write the modified file to memory Instead of writing into the filebuf directly, make the functions to write the modified config file write into a buffer which can then be dumped into the lockfile for committing. This allows us to re-use the same code for modifying a locked configuration, as we can simply skip the last step of dumping the data to disk.
75a4636f	2015-05-29T16:56:38	git__tolower: a tolower() that isn't dumb Some brain damaged tolower() implementations appear to want to take the locale into account, and this may require taking some insanely aggressive lock on the locale and slowing down what should be the most trivial of trivial calls for people who just want to downcase ASCII.

63c0cc65	2015-04-27T16:29:00	config: cleanup some now-unused variables
9c26de0f	2015-04-27T15:38:44	config: lock the file for write before reading When writing a configuration file, we want to take a lock on the new file (eg, `config.lock`) before opening the configuration file (`config`) for reading so that we can prevent somebody from changing the contents underneath us.
2a950c94	2015-04-27T10:43:50	config: write existing lines as-is when rewriting When updating a configuration file, we want to copy the old data from the file to preserve comments and funny whitespace, instead of writing it in some "canonical" format. Thus, we keep a pointer to the start of the line and the line length to preserve these things we don't care to rewrite.
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.

9a810c5e	2015-04-16T15:32:16	git_config_delete: search until last section. If git_config_delete is to work properly in the presence of duplicate section headers, it cannot stop searching at the end of the first matching section, as there may be another matching section later. When config_write is used for deletion (value = NULL), it may only terminate when the desired key is found or there are no sections left to parse.
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.
7f2e61f3	2015-04-19T23:55:02	config_file: parse multilines generously Combine unquoting and multiline detection to avoid ambiguity when parsing.
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.
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.

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.
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.
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.

0a641647	2014-10-04T23:27:06	config: Fix multiple trailing spaces before comments not completely trimmed
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.

2280b388	2014-04-09T13:17:51	config: share the strmap on snapshot Now that our strmap is no longer modified but replaced, we can use the same strmap for the snapshot's values and it will be freed when we don't need it anymore.
4b99b8f5	2014-04-09T13:08:01	config: refcount the values map This is mostly groundwork to let us re-use the map in the snapshots.
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.
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.
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.

bd95f836	2014-03-31T08:08:17	config: split out the refresh step This will be used by the writing commands in a later step.
c047317e	2014-03-18T17:54:32	config: make refresh atomic Current code sets the active map to a new one and builds it whilst it's active. This is a race condition with someone else trying to access the same config. Instead, let's build up our new map and swap the active and new one.
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.
40ed4990	2014-02-11T14:45:37	Add diff threading tests and attr file cache locks This adds a basic test of doing simultaneous diffs on multiple threads and adds basic locking for the attr file cache because that was the immediate problem that arose from these tests.

6014b7b5	2013-12-30T18:08:04	Fixed a compile error in VS2013.
9f77b3f6	2013-11-25T14:21:34	Add config read fns with controlled error behavior This adds `git_config__lookup_entry` which will look up a key in a config and return either the entry or NULL if the key was not present. Optionally, it can either suppress all errors or can return them (although not finding the key is not an error for this function). Unlike other accessors, this does not normalize the config key string, so it must only be used when the key is known to be in normalized form (i.e. all lower-case before the first dot and after the last dot, with no invalid characters). This also adds three high-level helper functions to look up config values with no errors and a fallback value. The three functions are for string, bool, and int values, and will resort to the fallback value for any error that arises. They are: * `git_config__get_string_force` * `git_config__get_bool_force` * `git_config__get_int_force` None of them normalize the config `key` either, so they can only be used for internal cases where the key is known to be in normal format.

Introduce a `write_start` variable which indicates where we should start writing from, which is what the `data_start` was being wrongly reused to be.

3793fa9b	2013-10-31T01:08:50	Fix saving remotes with several fetch/push ref specs. At some moment git_config_delete_entry lost the ability to delete one entry of a multivar configuration. The moment you had more than one fetch or push ref spec for a remote you will not be able to save that remote anymore. The changes in network::remote::remotes::save show that problem. I needed to create a new git_config_delete_multivar because I was not able to remove one or several entries of a multivar config with the current API. Several tries modifying how git_config_set_multivar(..., NULL) behaved were not successful. git_config_delete_multivar is very similar to git_config_set_multivar, and delegates into config_delete_multivar of config_file. This function search for the cvar_t that will be deleted, storing them in a temporal array, and rebuilding the linked list. After calling config_write to delete the entries, the cvar_t stored in the temporal array are freed. There is a little fix in config_write, it avoids an infinite loop when using a regular expression (case for the multivars). This error was found by the test network::remote::remotes::tagopt.

a9f51e43	2013-09-11T22:00:36	Merge git_buf and git_buffer This makes the git_buf struct that was used internally into an externally available structure and eliminates the git_buffer. As part of that, some of the special cases that arose with the externally used git_buffer were blended into the git_buf, such as being careful about git_buf objects that may have a NULL ptr and allowing for bufs with a valid ptr and size but zero asize as a way of referring to externally owned data.

config_file: handle error when trying to lock strmap Accessing the current values map is handled through the `refcounder_strmap_take` function, which first acquires a mutex before accessing its values. While this assures everybody is trying to access the values with the mutex only we do not check if the locking actually succeeds. Fix the issue by checking if acquiring the lock succeeds and returning `NULL` if we encounter an error. Adjust callers.

config_file: handle missing quotation marks in section header When parsing a section header we expect something along the format of '[section "subsection"]'. When a section is mal-formated and is entirely missing its quotation marks we catch this case by observing that `strchr(line, '"') - strrchr(line, '"') = NULL - NULL = 0` and error out. Unfortunately, the error message is misleading though, as we state that we are missing the closing quotation mark while we in fact miss both quotation marks. Improve the error message by explicitly checking if the first quotation mark could be found and, if not, stating that quotation marks are completely missing.

config: buffer comments to match git's variable-adding When there is a comment at the end of a section, git keeps it there, while we write the new variable right at the end. Keep comments buffered and dump them when we're going to output a variable or section, or reach EOF. This puts us in line with the config files which git produces.

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.

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.

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.

Add config read fns with controlled error behavior This adds `git_config__lookup_entry` which will look up a key in a config and return either the entry or NULL if the key was not present. Optionally, it can either suppress all errors or can return them (although not finding the key is not an error for this function). Unlike other accessors, this does not normalize the config key string, so it must only be used when the key is known to be in normalized form (i.e. all lower-case before the first dot and after the last dot, with no invalid characters). This also adds three high-level helper functions to look up config values with no errors and a fallback value. The three functions are for string, bool, and int values, and will resort to the fallback value for any error that arises. They are: * `git_config__get_string_force` * `git_config__get_bool_force` * `git_config__get_int_force` None of them normalize the config `key` either, so they can only be used for internal cases where the key is known to be in normal format.

Fix saving remotes with several fetch/push ref specs. At some moment git_config_delete_entry lost the ability to delete one entry of a multivar configuration. The moment you had more than one fetch or push ref spec for a remote you will not be able to save that remote anymore. The changes in network::remote::remotes::save show that problem. I needed to create a new git_config_delete_multivar because I was not able to remove one or several entries of a multivar config with the current API. Several tries modifying how git_config_set_multivar(..., NULL) behaved were not successful. git_config_delete_multivar is very similar to git_config_set_multivar, and delegates into config_delete_multivar of config_file. This function search for the cvar_t that will be deleted, storing them in a temporal array, and rebuilding the linked list. After calling config_write to delete the entries, the cvar_t stored in the temporal array are freed. There is a little fix in config_write, it avoids an infinite loop when using a regular expression (case for the multivars). This error was found by the test network::remote::remotes::tagopt.
