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.

a7a64d2c	2013-11-02T18:36:34	remote: don't write too much when dealing with multivars We used to move `data_start` forward, which is wrong as that needs to point to the beginning of the buffer in order to perform size calculations. 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.
53ea0513	2013-09-07T19:07:39	config: handle realloc issues from larger depths As the include depth increases, the chance of a realloc increases. This means that whenever we run git_array_alloc() or call config_parse(), we need to remember what our reader's index is so we can look it up again.

d209cc47	2013-09-05T18:06:12	config: decouple the backend from the reader at the low level In order to support config includes, we must differentiate between the backend's main file and the file we are currently parsing. This lays the groundwork for includes, keeping the current behaviours.

c57f6682	2013-08-08T21:17:32	config: allow empty string as value `git_config_set_string(config, "config.section", "")` fails when escaping the value. The buffer in `escape_value` is allocated without NULL-termination. And in case of empty string 0 is passed for buffer size in `git_buf_grow`. `git_buf_detach` returns NULL when the allocated size is 0 and that leads to an error return in `GITERR_CHECK_ALLOC` called after `escape_value` The change in `config_file.c` was suggested by Russell Belfer <rb@github.com>

7bf87ab6	2012-11-28T09:58:48	Consolidate text buffer functions There are many scattered functions that look into the contents of buffers to do various text manipulations (such as escaping or unescaping data, calculating text stats, guessing if content is binary, etc). This groups all those functions together into a new file and converts the code to use that. This has two enhancements to existing functionality. The old text stats function is significantly rewritten and the BOM detection code was extended (although largely we can't deal with anything other than a UTF8 BOM).

bcad677b	2012-11-08T12:28:21	- Update 'tests-clar/resources/config/config11' in order to reproduce the invalidread with the unittest (just added some \n at the end of the file) - Fix config_file.c
744cc03e	2012-10-30T12:10:36	Add git_config_refresh() API to reload config This adds a new API that allows users to reload the config if the file has changed on disk. A new config callback function to refresh the config was added. The modified time and file size are used to test if the file needs to be reloaded (and are now stored in the disk backend object). In writing tests, just using mtime was a problem / race, so I wanted to check file size as well. To support that, I extended `git_futils_readbuffer_updated` to optionally check file size in addition to mtime, and I added a new function `git_filebuf_stats` to fetch the mtime and size for an open filebuf (so that the config could be easily refreshed after a write). Lastly, I moved some similar file checking code for attributes into filebuf. It is still only being used for attrs, but it seems potentially reusable, so I thought I'd move it over.
a1abe66a	2012-09-10T12:11:02	Add config level support in the config API Added `struct git_config_entry`: a git_config_entry contains the key, the value, and the config file level from which a config element was found. Added `git_config_open_level`: build a single-level focused config object from a multi-level one. We are now storing `git_config_entry`s in the khash of the config_file
f8ede948	2012-09-18T14:10:40	Fix adding variable to config file with no trailing newline This can occur after a manual modification of a config file.
b200a813	2012-09-14T20:43:47	config: fix Unicode BOM detection Defining the BOM as a string makes the array include the NUL-terminator, which means that the memcpy is going to check for that as well and thus never match for a nonempty file. Define the array as three chars, which makes the size correct.
f335ecd6	2012-08-30T14:24:16	Diff iterators This refactors the diff output code so that an iterator object can be used to traverse and generate the diffs, instead of just the `foreach()` style with callbacks. The code has been rearranged so that the two styles can still share most functions. This also replaces `GIT_REVWALKOVER` with `GIT_ITEROVER` and uses that as a common error code for marking the end of iteration when using a iterator style of object.
0c8858de	2012-08-03T14:28:07	Fix valgrind issues and leaks This fixes up a number of problems flagged by valgrind and also cleans up the internal `git_submodule` allocation handling overall with a simpler model.

a1ecddf0	2012-08-12T07:59:30	Fix config parser boundary logic The config file parser was not working right if there was no whitespace between the value name and the equals sign. This fixes that.
5dca2010	2012-08-03T17:08:01	Update iterators for consistency across library This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.
5d9cfa07	2012-07-20T17:52:53	config: escape subsection names when creating them This allows us to set options like "some.foo\\ish.var". This closes #830
b3ff1dab	2012-07-10T15:22:39	Adding git_config_foreach_match() iteration fn Adding a new config iteration function that let's you iterate over just the config entries that match a particular regular expression. The old foreach becomes a simple use of this with an empty pattern. This also fixes an apparent bug in the existing `git_config_foreach` where returning a non-zero value from the iteration callback was not correctly aborting the iteration and the returned value was not being propogated back to the caller of foreach. Added to tests to cover all these changes.
49938cad	2012-06-11T16:28:51	config: correctly escape quotes in the value When a configuration option is set, we didn't check to see whether there was any escaping needed. Escape the available characters so we can unescape them correctly when we read them.

c2b67043	2012-04-25T15:20:28	Rename git_khash_str to git_strmap, etc. This renamed `git_khash_str` to `git_strmap`, `git_hash_oid` to `git_oidmap`, and deletes `git_hashtable` from the tree, plus adds unit tests for `git_strmap`.
01fed0a8	2012-04-25T10:36:01	Convert hashtable usage over to khash This updates khash.h with some extra features (like error checking on allocations, ability to use wrapped malloc, foreach calls, etc), creates two high-level wrappers around khash: `git_khash_str` and `git_khash_oid` for string-to-void-ptr and oid-to-void-ptr tables, then converts all of the old usage of `git_hashtable` over to use these new hashtables. For `git_khash_str`, I've tried to create a set of macros that yield an API not too unlike the old `git_hashtable` API. Since the oid hashtable is only used in one file, I haven't bother to set up all those macros and just use the khash APIs directly for now.
2bc8fa02	2012-04-17T10:14:24	Implement git_pool paged memory allocator This adds a `git_pool` object that can do simple paged memory allocation with free for the entire pool at once. Using this, you can replace many small allocations with large blocks that can then cheaply be doled out in small pieces. This is best used when you plan to free the small blocks all at once - for example, if they represent the parsed state from a file or data stream that are either all kept or all discarded. There are two real patterns of usage for `git_pools`: either for "string" allocation, where the item size is a single byte and you end up just packing the allocations in together, or for "fixed size" allocation where you are allocating a large object (e.g. a `git_oid`) and you generally just allocation single objects that can be tightly packed. Of course, you can use it for other things, but those two cases are the easiest.

bfc9ca59	2012-03-28T16:45:36	Added submodule API and use in status When processing status for a newly checked out repo, it is possible that there will be submodules that have not yet been initialized. The only way to distinguish these from untracked directories is to have some knowledge of submodules. This commit adds a new submodule API which, given a name or path, can determine if it appears to be a submodule and can give information about the submodule.
54fef6eb	2012-03-09T20:38:32	config: write out section headers with subsections correctly write_section() mistakenly treated is input as the whole variable name instead of simply the section (and possibly subsection) and would confuse "section.subsection" as a section plus variable name and produce a wrong section header. Fix this and include a test for writing "section.subsection.var" and reading it from the file.
dda708e7	2012-03-09T19:55:50	error-handling: On-disk config file backend Includes: - Proper error reporting when encountering syntax errors in a config file (file, line number, column). - Rewritten `config_write`, now with 99% less goto-spaghetti - Error state in `git_filebuf`: filebuf write functions no longer need to be checked for error returns. If any of the writes performed on a buffer fail, the last call to `git_filebuf_commit` or `git_filebuf_hash` will fail accordingly and set the appropiate error message. Baller!
854eccbb	2012-02-29T12:04:59	Clean up GIT_UNUSED macros on all platforms It turns out that commit 31e9cfc4cbcaf1b38cdd3dbe3282a8f57e5366a5 did not fix the GIT_USUSED behavior on all platforms. This commit walks through and really cleans things up more thoroughly, getting rid of the unnecessary stuff. To remove the use of some GIT_UNUSED, I ended up adding a couple of new iterators for hashtables that allow you to iterator just over keys or just over values. In making this change, I found a bug in the clar tests (where we were doing count++ but meant to do (count)++ to increment the value). I fixed that but then found the test failing because it was not really using an empty repo. So, I took some of the code that I wrote for iterator testing and moved it to clar_helpers.c, then made use of that to make it easier to open fixtures on a per test basis even within a single test file.
13224ea4	2012-02-27T04:28:31	buffer: Unify `git_fbuffer` and `git_buf` This makes so much sense that I can't believe it hasn't been done before. Kill the old `git_fbuffer` and read files straight into `git_buf` objects. Also: In order to fully support 4GB files in 32-bit systems, the `git_buf` implementation has been changed from using `ssize_t` for storage and storing negative values on allocation failure, to using `size_t` and changing the buffer pointer to a magical pointer on allocation failure. Hopefully this won't break anything.
0a43d7cb	2012-02-25T18:52:28	config: correctly deal with setting a multivar with regex where there are no matches We used to erroneously consider "^$" as a special case for appending a value to a multivar. This was a misunderstanding and we should always append a value if there are no existing values that match. While we're in the area, replace all the variables in-memory in one swoop and then replace them on disk so as to avoid matching a value we've just introduced.

The rest of the code doesn't recognize this form and we hadn't noticed because most tests don't try to get a recently-set variable but free and reload the configuration, causing the right format to be used.
c1c399cf	2012-01-13T19:33:54	config: handle EOF properly In the main loop we peek to see what kind of line the next one is. If there are multiple newlines before the end of the file, the eof marker won't be set after we read the last line with data and we'll try to peek again. This peek will return LF (as it pretends that we have a newline at EOF so other function don't need any special handling). Fix cfg_getchar so it doesn't try to read past the last character in the file and config_parse so it considers LF as EOF on peek (as we're ignoring spaces) and sets the reader's EOF flag to exit the parsing loop.

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.

remote: don't write too much when dealing with multivars We used to move `data_start` forward, which is wrong as that needs to point to the beginning of the buffer in order to perform size calculations. 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.

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.

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: allow empty string as value `git_config_set_string(config, "config.section", "")` fails when escaping the value. The buffer in `escape_value` is allocated without NULL-termination. And in case of empty string 0 is passed for buffer size in `git_buf_grow`. `git_buf_detach` returns NULL when the allocated size is 0 and that leads to an error return in `GITERR_CHECK_ALLOC` called after `escape_value` The change in `config_file.c` was suggested by Russell Belfer <rb@github.com>

Consolidate text buffer functions There are many scattered functions that look into the contents of buffers to do various text manipulations (such as escaping or unescaping data, calculating text stats, guessing if content is binary, etc). This groups all those functions together into a new file and converts the code to use that. This has two enhancements to existing functionality. The old text stats function is significantly rewritten and the BOM detection code was extended (although largely we can't deal with anything other than a UTF8 BOM).

Add git_config_refresh() API to reload config This adds a new API that allows users to reload the config if the file has changed on disk. A new config callback function to refresh the config was added. The modified time and file size are used to test if the file needs to be reloaded (and are now stored in the disk backend object). In writing tests, just using mtime was a problem / race, so I wanted to check file size as well. To support that, I extended `git_futils_readbuffer_updated` to optionally check file size in addition to mtime, and I added a new function `git_filebuf_stats` to fetch the mtime and size for an open filebuf (so that the config could be easily refreshed after a write). Lastly, I moved some similar file checking code for attributes into filebuf. It is still only being used for attrs, but it seems potentially reusable, so I thought I'd move it over.

Diff iterators This refactors the diff output code so that an iterator object can be used to traverse and generate the diffs, instead of just the `foreach()` style with callbacks.

Update iterators for consistency across library This updates all the `foreach()` type functions across the library that take callbacks from the user to have a consistent behavior. The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules.

Adding git_config_foreach_match() iteration fn Adding a new config iteration function that let's you iterate over just the config entries that match a particular regular expression. The old foreach becomes a simple use of this with an empty pattern. This also fixes an apparent bug in the existing `git_config_foreach` where returning a non-zero value from the iteration callback was not correctly aborting the iteration and the returned value was not being propogated back to the caller of foreach. Added to tests to cover all these changes.

For `git_khash_str`, I've tried to create a set of macros that yield an API not too unlike the old `git_hashtable` API. Since the oid hashtable is only used in one file, I haven't bother to set up all those macros and just use the khash APIs directly for now.

Implement git_pool paged memory allocator This adds a `git_pool` object that can do simple paged memory allocation with free for the entire pool at once. Using this, you can replace many small allocations with large blocks that can then cheaply be doled out in small pieces. This is best used when you plan to free the small blocks all at once - for example, if they represent the parsed state from a file or data stream that are either all kept or all discarded. There are two real patterns of usage for `git_pools`: either for "string" allocation, where the item size is a single byte and you end up just packing the allocations in together, or for "fixed size" allocation where you are allocating a large object (e.g. a `git_oid`) and you generally just allocation single objects that can be tightly packed. Of course, you can use it for other things, but those two cases are the easiest.

Clean up GIT_UNUSED macros on all platforms It turns out that commit 31e9cfc4cbcaf1b38cdd3dbe3282a8f57e5366a5 did not fix the GIT_USUSED behavior on all platforms. This commit walks through and really cleans things up more thoroughly, getting rid of the unnecessary stuff. To remove the use of some GIT_UNUSED, I ended up adding a couple of new iterators for hashtables that allow you to iterator just over keys or just over values. In making this change, I found a bug in the clar tests (where we were doing *count++ but meant to do (*count)++ to increment the value). I fixed that but then found the test failing because it was not really using an empty repo. So, I took some of the code that I wrote for iterator testing and moved it to clar_helpers.c, then made use of that to make it easier to open fixtures on a per test basis even within a single test file.

buffer: Unify `git_fbuffer` and `git_buf` This makes so much sense that I can't believe it hasn't been done before. Kill the old `git_fbuffer` and read files straight into `git_buf` objects. Also: In order to fully support 4GB files in 32-bit systems, the `git_buf` implementation has been changed from using `ssize_t` for storage and storing negative values on allocation failure, to using `size_t` and changing the buffer pointer to a magical pointer on allocation failure. Hopefully this won't break anything.

If there are multiple newlines before the end of the file, the eof marker won't be set after we read the last line with data and we'll try to peek again. This peek will return LF (as it pretends that we have a newline at EOF so other function don't need any special handling). Fix cfg_getchar so it doesn't try to read past the last character in the file and config_parse so it considers LF as EOF on peek (as we're ignoring spaces) and sets the reader's EOF flag to exit the parsing loop.

config: really delete variables Instead of just setting the value to NULL, which gives unwanted results when asking for that variable after deleting it, delete the variable from the list and re-write the file.
