Returns: a builtin file object or a _GitFile object Note: See _GitFile for a description of the file locking protocol. Only read-only and write-only (binary) modes are supported; r+, w+, and a are not. To read and write from the same file, you can take advantage of the fact that opening a file for write does not actually open the file you request. The default file mask makes any created files user-writable and world-readable. az'append mode not supported for Git files+z+read/write mode not supported for Git filesbz%text mode not supported for Git filesw)r_GitFileopen)filenamemodebufsizemaskrrr GitFileGs r(cs"eZdZdZdfdd ZZS) FileLockedzFile is already locked.rNcs||_||_t||dSN)r$ lockfilenamesuper__init__)selfr$r+ __class__rr r-fszFileLocked.__init__rN)__name__ __module__ __qualname____doc__r- __classcell__rrr/r r)csr)c@seZdZUdZhdZeeeed<hdZ eeeed<ddd Z dd d Z dd d Z dddZ ddZddZddZdS)r"apFile that follows the git locking protocol for writes. All writes to a file foo will be written into foo.lock in the same directory, and the lockfile will be renamed to overwrite the original file on close. Note: You *must* call close() or abort() on a _GitFile for the lock to be released. Typically this will happen in a finally block. >r%nameclosederrorsencodingnewlines softspacePROXY_PROPERTIES> readseektellflushwritefilenoisatty__iter__readlinetruncate readlines writelines PROXY_METHODSrNc Cs||_t|jtr|jd|_n|jd|_zt|jtjtjBtjBt tddB|}Wnt y@}zt ||j|d}~wwt ||||_ d|_|jD] }t||t |j |qOdS)Ns.lockz.lockO_BINARYrF) _filename isinstancebytes _lockfilenamerr#O_RDWRO_CREATO_EXCLgetattrrr)fdopen_file_closedrJsetattr)r.r$r%r&r'rexcmethodrrr r-s&   z_GitFile.__init__cCsH|jrdS|jz t|jd|_WdSty#d|_YdSw)zClose and discard the lockfile without overwriting the target.

Note: If this method fails, it will attempt to delete the lockfile. However, it is not guaranteed to do so (e.g. if a filesystem becomes suddenly read-only), which will prevent future writes to this file until the lockfile is removed manually. Raises: OSError: if the original file could not be overwritten. The lock file is still closed, so further attempts to write to the same file object will raise ValueError.
