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.

2d2e70f8	2017-11-30T18:10:28	openssl: fix thread-safety on non-glibc POSIX systems While the OpenSSL library provides all means to work safely in a multi-threaded application, we fail to do so correctly. Quoting from crypto_lock(3): OpenSSL can safely be used in multi-threaded applications provided that at least two callback functions are set, locking_function and threadid_func. We do in fact provide the means to set up the locking function via `git_openssl_set_locking()`, where we initialize a set of locks by using the POSIX threads API and set the correct callback function to lock and unlock them. But what we do not do is setting the `threadid_func` callback. This function is being used to correctly locate thread-local data of the OpenSSL library and should thus return per-thread identifiers. Digging deeper into OpenSSL's documentation, the library does provide a fallback in case that locking function is not provided by the user. On Windows and BeOS we should be safe, as it simply "uses the system's default thread identifying API". On other platforms though OpenSSL will fall back to using the address of `errno`, assuming it is thread-local. While this assumption holds true for glibc-based systems, POSIX in fact does not specify whether it is thread-local or not. Quoting from errno(3p): It is unspecified whether errno is a macro or an identifier declared with external linkage. And in fact, with musl there is at least one libc implementation which simply declares `errno` as a simple `int` without being thread-local. On those systems, the fallback threadid function of OpenSSL will not be thread-safe. Fix this by setting up our own callback for this setting. As users of libgit2 may want to set it themselves, we obviously cannot always set that function on initialization. But as we already set up primitives for threading in `git_openssl_set_locking()`, this function becomes the obvious choice where to implement the additional setup.
5ca3f115	2017-11-30T15:12:48	diff_generate: fix unsetting diff flags The macro `DIFF_FLAG_SET` can be used to set or unset a flag by modifying the diff's bitmask. While the case of setting the flag is handled correctly, the case of unsetting the flag was not. Instead of inverting the flags, we are inverting the value which is used to decide whether we want to set or unset the bits. The value being used here is a simple `bool` which is `false`. As that is being uplifted to `int` when getting the bitwise-complement, we will end up retaining all bits inside of the bitmask. As that's only ever used to set `GIT_DIFF_IGNORE_CASE`, we were actually always ignoring case for generated diffs. Fix that by instead getting the bitwise-complement of `FLAG`, not `VAL`.
90fc7f53	2017-11-30T15:09:05	diff: remove unused macros `DIFF_FLAG_*` In commit 9be638ecf (git_diff_generated: abstract generated diffs, 2016-04-19), the code for generated diffs was moved out of the generic "diff.c" and instead into its own module. During that conversion, it was forgotten to remove the macros `DIFF_FLAG_IS_SET`, `DIFF_FLAG_ISNT_SET` and `DIFF_FLAG_SET`, which are now only used in "diff_generated.c". Remove those macros now.

585b5dac	2017-11-18T15:43:11	refcount: make refcounting conform to aliasing rules Strict aliasing rules dictate that for most data types, you are not allowed to cast them to another data type and then access the casted pointers. While this works just fine for most compilers, technically we end up in undefined behaviour when we hurt that rule. Our current refcounting code makes heavy use of casting and thus violates that rule. While we didn't have any problems with that code, Travis started spitting out a lot of warnings due to a change in their toolchain. In the refcounting case, the code is also easy to fix: as all refcounting-statements are actually macros, we can just access the `rc` field directly instead of casting. There are two outliers in our code where that doesn't work. Both the `git_diff` and `git_patch` structures have specializations for generated and parsed diffs/patches, which directly inherit from them. Because of that, the refcounting code is only part of the base structure and not of the children themselves. We can help that by instead passing their base into `GIT_REFCOUNT_INC`, though.

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

9e66590b	2017-07-21T13:01:43	config_parse: use common parser interface As the config parser is now cleanly separated from the config file code, we can easily refactor the code and make use of the common parser module. This removes quite a lot of duplicated functionality previously used for handling the actual parser state and replaces it with the generic interface provided by the parser context.
1953c68b	2017-11-11T17:12:31	config_file: split out module to parse config files The configuration file code grew quite big and intermingles both actual configuration logic as well as the parsing logic of the configuration syntax. This makes it hard to refactor the parsing logic on its own and convert it to make use of our new parsing context module. Refactor the code and split it up into two parts. The config file code will only handle actual handling of configuration files, includes and writing new files. The newly created config parser module is then only responsible for parsing the actual contents of a configuration file, leaving everything else to callbacks provided to its provided function `git_config_parse`.
7bdfc0a6	2017-07-14T15:33:32	parse: always initialize line pointer Upon initializing the parser context, we do not currently initialize the current line, line length and line number. Do so in order to make the interface easier to use and more obvious for future consumers of the parsing API.
e72cb769	2017-07-14T14:37:07	parse: implement `git_parse_peek` Some code parts need to inspect the next few bytes without actually consuming it yet, for example to examine what content it has to expect next. Create a new function `git_parse_peek` which returns the next byte without modifying the parsing context and use it at multiple call sites.
252f2eee	2017-07-14T13:45:05	parse: implement and use `git_parse_advance_digit` The patch parsing code has multiple recurring patterns where we want to parse an actual number. Create a new function `git_parse_advance_digit` and use it to avoid code duplication.
65dcb645	2017-07-14T13:29:29	patch_parse: use git_parse_contains_s Instead of manually checking the parsing context's remaining length and comparing the leading bytes with a specific string, we can simply re-use the function `git_parse_ctx_contains_s`. Do so to avoid code duplication and to further decouple patch parsing from the parsing context's struct members.
ef1395f3	2017-11-11T15:30:43	parse: extract parse module The `git_patch_parse_ctx` encapsulates both parser state as well as options specific to patch parsing. To advance this state and keep it consistent, we provide a few functions which handle advancing the current position and accessing bytes of the patch contents. In fact, these functions are quite generic and not related to patch-parsing by themselves. Seeing that we have similar logic inside of other modules, it becomes quite enticing to extract this functionality into its own parser module. To do so, we create a new module `parse` with a central struct called `git_parse_ctx`. It encapsulates both the content that is to be parsed as well as its lengths and the current position. `git_patch_parse_ctx` now only contains this `parse_ctx` only, which is then accessed whenever we need to touch the current parser. This is the first step towards re-using this functionality across other modules which require parsing functionality and remove code-duplication.
a0b0b808	2017-11-11T14:03:14	cmake: Allow user to select bundled zlib Under some circumstances the installed / system version of zlib may not be desirable due to being too old or buggy.

As our networking example code makes use of getline, this breaks builds on MSVC and MinGW. As this code wasn't built prior to the previous commit, this was never noticed.

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.

openssl: fix thread-safety on non-glibc POSIX systems While the OpenSSL library provides all means to work safely in a multi-threaded application, we fail to do so correctly. Quoting from crypto_lock(3): OpenSSL can safely be used in multi-threaded applications provided that at least two callback functions are set, locking_function and threadid_func. We do in fact provide the means to set up the locking function via `git_openssl_set_locking()`, where we initialize a set of locks by using the POSIX threads API and set the correct callback function to lock and unlock them. But what we do not do is setting the `threadid_func` callback. This function is being used to correctly locate thread-local data of the OpenSSL library and should thus return per-thread identifiers. Digging deeper into OpenSSL's documentation, the library does provide a fallback in case that locking function is not provided by the user. On Windows and BeOS we should be safe, as it simply "uses the system's default thread identifying API". On other platforms though OpenSSL will fall back to using the address of `errno`, assuming it is thread-local. While this assumption holds true for glibc-based systems, POSIX in fact does not specify whether it is thread-local or not. Quoting from errno(3p): It is unspecified whether errno is a macro or an identifier declared with external linkage. And in fact, with musl there is at least one libc implementation which simply declares `errno` as a simple `int` without being thread-local. On those systems, the fallback threadid function of OpenSSL will not be thread-safe. Fix this by setting up our own callback for this setting. As users of libgit2 may want to set it themselves, we obviously cannot always set that function on initialization. But as we already set up primitives for threading in `git_openssl_set_locking()`, this function becomes the obvious choice where to implement the additional setup.

diff_generate: fix unsetting diff flags The macro `DIFF_FLAG_SET` can be used to set or unset a flag by modifying the diff's bitmask. While the case of setting the flag is handled correctly, the case of unsetting the flag was not. Instead of inverting the flags, we are inverting the value which is used to decide whether we want to set or unset the bits. The value being used here is a simple `bool` which is `false`. As that is being uplifted to `int` when getting the bitwise-complement, we will end up retaining all bits inside of the bitmask. As that's only ever used to set `GIT_DIFF_IGNORE_CASE`, we were actually always ignoring case for generated diffs. Fix that by instead getting the bitwise-complement of `FLAG`, not `VAL`.

diff: remove unused macros `DIFF_FLAG_*` In commit 9be638ecf (git_diff_generated: abstract generated diffs, 2016-04-19), the code for generated diffs was moved out of the generic "diff.c" and instead into its own module. During that conversion, it was forgotten to remove the macros `DIFF_FLAG_IS_SET`, `DIFF_FLAG_ISNT_SET` and `DIFF_FLAG_SET`, which are now only used in "diff_generated.c". Remove those macros now.

Unlike `make test`, it gives output. Users getting started with the library believe that it is hung. 2. `ctest -V` shows verbose output; showing suite names is helpful for giving users more feedback immediately.

585b5dac

2017-11-18T15:43:11

refcount: make refcounting conform to aliasing rules Strict aliasing rules dictate that for most data types, you are not allowed to cast them to another data type and then access the casted pointers. While this works just fine for most compilers, technically we end up in undefined behaviour when we hurt that rule. Our current refcounting code makes heavy use of casting and thus violates that rule. While we didn't have any problems with that code, Travis started spitting out a lot of warnings due to a change in their toolchain. In the refcounting case, the code is also easy to fix: as all refcounting-statements are actually macros, we can just access the `rc` field directly instead of casting. There are two outliers in our code where that doesn't work. Both the `git_diff` and `git_patch` structures have specializations for generated and parsed diffs/patches, which directly inherit from them. Because of that, the refcounting code is only part of the base structure and not of the children themselves. We can help that by instead passing their base into `GIT_REFCOUNT_INC`, though.

f063dafb

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

config_parse: use common parser interface As the config parser is now cleanly separated from the config file code, we can easily refactor the code and make use of the common parser module. This removes quite a lot of duplicated functionality previously used for handling the actual parser state and replaces it with the generic interface provided by the parser context.

config_file: split out module to parse config files The configuration file code grew quite big and intermingles both actual configuration logic as well as the parsing logic of the configuration syntax. This makes it hard to refactor the parsing logic on its own and convert it to make use of our new parsing context module. Refactor the code and split it up into two parts. The config file code will only handle actual handling of configuration files, includes and writing new files. The newly created config parser module is then only responsible for parsing the actual contents of a configuration file, leaving everything else to callbacks provided to its provided function `git_config_parse`.

2017-07-14T13:29:29

patch_parse: use git_parse_contains_s Instead of manually checking the parsing context's remaining length and comparing the leading bytes with a specific string, we can simply re-use the function `git_parse_ctx_contains_s`. Do so to avoid code duplication and to further decouple patch parsing from the parsing context's struct members.

ef1395f3

2017-11-11T15:30:43

parse: extract parse module The `git_patch_parse_ctx` encapsulates both parser state as well as options specific to patch parsing. To advance this state and keep it consistent, we provide a few functions which handle advancing the current position and accessing bytes of the patch contents. In fact, these functions are quite generic and not related to patch-parsing by themselves. Seeing that we have similar logic inside of other modules, it becomes quite enticing to extract this functionality into its own parser module. To do so, we create a new module `parse` with a central struct called `git_parse_ctx`. It encapsulates both the content that is to be parsed as well as its lengths and the current position. `git_patch_parse_ctx` now only contains this `parse_ctx` only, which is then accessed whenever we need to touch the current parser. This is the first step towards re-using this functionality across other modules which require parsing functionality and remove code-duplication.

As our networking example code makes use of getline, this breaks builds on MSVC and MinGW. As this code wasn't built prior to the previous commit, this was never noticed. Fix the error by instead implementing a `readline` function, which simply reads the password from stdin until it reads a newline character.
