2020-12-09common/file_util: Simplify the behavior of CreateFullPathMorph
2020-12-09common/file_util: Let std::filesystem cast from UTF16 to std::stringReinUsesLisp
Fix invalid encoding paths when iterating over a directory on Windows.
2020-12-09common/file_util: Fix and deprecate CreateFullPath, add CreateDirsReinUsesLisp
Fix CreateFullPath to have its intended previous behavior (whatever that was), and deprecate it in favor of the new CreateDirs function. Unlike CreateDir, CreateDirs is marked as [[nodiscard]] to avoid new code ignoring its result value.
2020-12-09common/file_util: Succeed on CreateDir when the directory existsReinUsesLisp
2020-12-09file_util: Migrate remaining file handling functions over to std::filesystemLioncash
Converts creation and deletion functions over to std::filesystem, simplifying our file-handling code. Notably with this, CopyDir will now function on Windows.
2020-12-08file_util: Migrate Exists() and IsDirectory() over to std::filesystemLioncash
Greatly simplifies our file-handling code for these functions.
2020-11-02common: Enable warnings as errorsLioncash
Cleans up common so that we can enable warnings as errors.
2020-08-18Merge pull request #4539 from lioncash/discbunnei
common: Silence two discarded result warnings
2020-08-16common/fileutil: Convert namespace to Common::FSLioncash
Migrates a remaining common file over to the Common namespace, making it consistent with the rest of common files. This also allows for high-traffic FS related code to alias the filesystem function namespace as namespace FS = Common::FS; for more concise typing.
2020-08-16common: Silence two discarded result warningsLioncash
These are intentionally discarded internally, since the rest of the public API allows querying success. We want all non-internal uses of these functions to be explicitly checked, so we can signify that we intentionally want to discard the return values here.
2020-07-20common: Add a screenshots directorylat9nq
Adds a screenshots directory as a path managed by FileUtil.

common/file_util: Allow access to files on network shares
2020-04-15file_util: Early-exit in WriteArray and ReadArray if specified lengths are zeroLioncash
It's undefined behavior to pass a null pointer to std::fread and std::fwrite, even if the length passed in is zero, so we must perform the precondition checking ourselves. A common case where this can occur is when passing in the data of an empty std::vector and size, as an empty vector will typically have a null internal buffer. While we're at it, we can move the implementation out of line and add debug checks against passing in nullptr to std::fread and std::fwrite.
2020-04-09common/file_util: Allow access to files on network sharesBen Russell
On Windows, network shares use paths like \\server\share\file which were being broken by FileUtil::SanitizePath() removing double slashes. Changed the code in SanitizePath to permit a double-backslash if it occurs at the start of a filepath (on Windows only).
2020-04-01common: Port some changes from dolphin (#5127)Vitor K
* IOFile: Make the move constructor and move assignment operator noexcept Certain parts of the standard library try to determine whether or not a transfer operation should either be a copy or a move. The prevalent notion of move constructors/assignment operators is that they should not throw, they simply move an already existing resource somewhere else. This is typically done with 'std::move_if_noexcept'. Like the name says, if a type's move constructor is noexcept, then the functions retrieves an r-value reference (for move semantics), or an l-value (for copy semantics) if it is not noexcept. As IOFile deletes the copy constructor and copy assignment operators, using IOFile with certain parts of the standard library can fail in unexcepted ways (especially when used with various container implementations). This prevents that. * fix various instances of -1 being assigned to unsigned types * do not assign in conditional statements * File/IOFile: Check _tfopen_s properly * common/file_util.cpp: address review comments Co-authored-by: Lioncash <mathew1800@gmail.com> Co-authored-by: Shawn Hoffman <godisgovernment@gmail.com> Co-authored-by: Sepalani <sepalani@hotmail.fr>
2019-10-04common/file_util: Silence -WswitchReinUsesLisp
2019-05-23common/file_util: Remove unnecessary return at end of void StripTailDirSlashes()Lioncash
While we're at it, also invert the conditional into a guard clause.
2019-05-23common/file_util: Make GetCurrentDir() return a std::optionalLioncash
nullptr was being returned in the error case, which, at a glance may seem perfectly OK... until you realize that std::string has the invariant that it may not be constructed from a null pointer. This means that if this error case was ever hit, then the application would most likely crash from a thrown exception in std::string's constructor. Instead, we can change the function to return an optional value, indicating if a failure occurred.
2019-05-23common/file_util: Remove duplicated documentation commentsLioncash
These are already present within the header, so they don't need to be repeated in the cpp file.
2019-05-23common/file_util: Make ReadFileToString and WriteStringToFile consistentLioncash
Makes the parameter ordering consistent, and also makes the filename parameter a std::string. A std::string would be constructed anyways with the previous code, as IOFile's only constructor with a filepath is one taking a std::string. We can also make WriteStringToFile's string parameter utilize a std::string_view for the string, making use of our previous changes to IOFile.

file_util, vfs: Use std::string_view where applicable
2018-07-22file_util, vfs: Use std::string_view where applicableLioncash
Avoids unnecessary construction of std::string instances where applicable.
2018-07-22Merge pull request #765 from lioncash/filebunnei
file_util: Remove goto usages from Copy()
2018-07-21file_util: Remove goto usages from Copy()Lioncash
We can just leverage std::unique_ptr to automatically close these for us in error cases instead of jumping to the end of the function to call fclose on them.
2018-07-21file_util: Use a u64 to represent number of entriesLioncash
This avoids a truncating cast on size. I doubt we'd ever traverse a directory this large, however we also shouldn't truncate sizes away.
2018-07-21file_util: std::move FST entries in ScanDirectoryTree()Lioncash
Avoids unnecessary copies when building up the FST entries.

file_util: Remove redundant duplicate return in GetPathWithoutTop()
2018-07-21file_util: Use an enum class for GetUserPath()Lioncash
Instead of using an unsigned int as a parameter and expecting a user to always pass in the correct values, we can just convert the enum into an enum class and use that type as the parameter type instead, which makes the interface more type safe. We also get rid of the bookkeeping "NUM_" element in the enum by just using an unordered map. This function is generally low-frequency in terms of calls (and I'd hope so, considering otherwise would mean we're slamming the disk with IO all the time) so I'd consider this acceptable in this case.
2018-07-21file_util: Remove explicit type from std::min() in GetPathWithoutTop()Lioncash
Given both operands are the same type, there won't be an issue with overload selection that requires making this explicit.
2018-07-21file_util: Remove redundant duplicate return in GetPathWithoutTop()Lioncash
2018-07-19file_util: return string by const reference for GetExeDirectory()Lioncash
This disallows modifying the internal string buffer (which shouldn't be modified anyhow).
