* Move source files into gfapi/ dirPrashanth Pai2016-08-102-9/+9
| | | | | | | | | | | | | | | | | Currently, many source files are directly placed under gluster/ dir: gluster/exceptions.py gluster/gfapi.py gluster/utils.py When multiple packages (RPMs) are sharing the same gluster namespace, these source files will conflict if there are source files with same names provided by other projects. Fix: Move all source files in gluster/* to gluster/gfapi/* Note that this patch does not break how existing users import gfapi.

* Implement copytree() and enhance walk(), rmtree()Prashanth Pai2016-08-031-61/+96
| | | | | | | | | | | This change: * Implements copytree() API which is very similar to the one provided by shutils built-in module in Python. * Enhances walk() and rmtree() implementation to leverage scandir() optimization.

* Expose glfs_readdirplus_rPrashanth Pai2016-06-301-2/+92
| | | | | | | | | | | | | | | | This patch does the following: * Implements Volume.listdir_with_stat() API which internally invokes glfs_readdirplus_r to return directory entries along with stat for each entry. * Implements Volume.scandir() which is similar to os.scandir() present in Python 3.5 * Makes Dir class iterable. * Enables Dir class to raise OSError when glfs_readdir* calls fail. Previously, these failures were silently being ignored and treated as a case of EOF. Change-Id: Id918c39a7ef3882553e9bcd3fbf9455ee1c25a83 Signed-off-by: Prashanth Pai <ppai@redhat.com>
* Fix license discrepanciesPrashanth Pai2016-06-172-20/+15
| | | | | | | | | | The repo had mixed references to both Apache BSD license and GPL licenses. This change removes references to Apache license. The license of this project is now same as that of GlusterFS. Change-Id: I39b72f59d14af304729560dd1d59fe307cd1ac1d Signed-off-by: Prashanth Pai <ppai@redhat.com>
* Add validation decoratorsPrashanth Pai2016-06-152-0/+101
| | | | | | | | | | As glfs and glfd are pointers to memory locations, passing invalid values of glfs and glfd to the libgfapi C library can result in segfault. This patch introduces decorators that validate glfs and glfd before calling correspoding C APIs. Change-Id: I4e86bd8e436e23cd41f75f428d246939c820bb9c Signed-off-by: Prashanth Pai <ppai@redhat.com>
* Implement os.utime() like API and zerofillPrashanth Pai2016-06-011-0/+34
| | | | | | | | | | | | This patch: * Implements Volume.utime() which is very similar to os.utime() present in Python. https://docs.python.org/2/library/os.html#os.utime * Implements File.zerofill() which exposes glfs_zerofill. * Fixes function prototype of fallocate and discard. Adds functional tests for the same. Change-Id: Icb8d3a571998c31d6bf9b139ca253af59f6fc3f4 Signed-off-by: Prashanth Pai <ppai@redhat.com>

* | Add readinto() APIPrashanth Pai2016-02-241-0/+11
|/ | | | | | | | | | readinto() This method is useful when you have to read a large file over multiple read calls. While read() allocates a buffer every time it's invoked, readinto() copies data to an already allocated buffer passed to it.

* Fix open/fopen in thread other than mainOleksiy Syvokon2015-08-311-5/+5
| | | | | | | | | | | | Before this patch, calling Volume.{f}open in a thread other than main thread was causing segmentation fault (test included). The reason is missing ctypes declarations. Also, this patch fixes errno handling for these two functions, making couple of FIXME/TODO notes go away.

* Fix reading of binary data in read()Prashanth Pai2015-06-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | As per the current code, this is the behavior: >>> with v.fopen("/abc", 'r') as f: ... data = f.read(5) >>> print data <ctypes.c_char_Array_2 object at 0x7fda7d6bbb90> >>> print data.value hello >>> It's incorrect to return a ctypes internal object back to the user. In Python 2.x, read() always returns a string. It's really upto the consumer to decode this string into whatever encoding it was written with.

* Add missing Path based operation APIsPrashanth Pai2015-06-181-5/+6
| | | | | | | | | | | | | * Added commonly used path based operations that were missing from the Volume class. * Fixed function prototypes at places where it should be ssize_t and not size_t. This caused overflow error at times. * Added doc strings wherever they were missing. Change-Id: I6ce28038da3cd0f89ab075045bb4092dd95e21c4 Signed-off-by: Prashanth Pai <ppai@redhat.com>
* Add missing File APIsPrashanth Pai2015-06-181-60/+43
| | | | | | | | | | | | | | | | | | | | | | | | | Volume.fopen() method mimics Python's built-in File object Example: with v.fopen("/path/to/file", "w") as f: f.write("hello world") fopen() returns a File object. Volume.open() method mimics os.open() Python API. Example: with File(v.open("/path/to/file", os.O_WRONLY | os.O_CREAT)) as f: f.write("hello world") open() returns the raw glfd that (as of today) needs to be passed to File class. In future, more APIs will be provided to directly use the glfd returned. Unlike their C versions, these methods do not return anything on success. If methods fail, exceptions are raised. Added docstrings to methods in File class. Change-Id: Ie46fc77a899806d396762e6740e1538ea298d6e2 Signed-off-by: Prashanth Pai <ppai@redhat.com> Signed-off-by: Thiago da Silva <thiago@redhat.com>
