[ "Material design drawer under the status bar: how to achieve it using a DrawerLayout with two FrameLayouts as children?", "I'm currently setting up the navigation drawer to follow the material design specs. I've already checked Chris Banes post (available in Material design checklist) and made all of the implementations listed there such as custom themes and so on, and this question as well, but none of them seem to meet the requirements of my app structure. \n\nAs you guessed from the title, my DrawerLayout has got two FrameLayouts as children: one for the content and another for the drawer (it is important to point out that I can't change this structure since I need to keep the ability to update the content in the NavigationDrawer dinamically and obviously to keep the ability to swap fragments as the main content).\n\nThe problem is now that I don't know where to put the toolbar declaration in xml in order to achieve the expected design and without messing all up, since the DrawerLayout requires two children.\n\nactivity_main.xml\n\n<android.support.v4.widget.DrawerLayout xmlns:android=\"http://schemas.android.com/apk/res/android\"\nxmlns:tools=\"http://schemas.android.com/tools\"\nandroid:id=\"@+id/drawer_layout\"\nandroid:layout_width=\"match_parent\"\nandroid:layout_height=\"match_parent\"\ntools:context=\"com.myapp.MainActivity\" \nandroid:fitsSystemWindows=\"false\"> <!-- Setting this one to true makes the status bar to have a non-transparent shitty background -->\n\n<!--\n As the main content view, the view below consumes the entire\n space available using match_parent in both dimensions.\n-->\n\n<FrameLayout\n android:id=\"@+id/container\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"match_parent\" >\n\n <android.support.v7.widget.Toolbar\n xmlns:app=\"http://schemas.android.com/apk/res-auto\"\n android:id=\"@+id/toolbar\"\n android:layout_height=\"wrap_content\"\n android:layout_width=\"match_parent\"\n android:minHeight=\"?attr/actionBarSize\"\n android:background=\"?attr/colorPrimary\" \n app:theme=\"@style/ThemeOverlay.AppCompat.ActionBar\" />\n\n </FrameLayout>\n\n<com.myapp.widget.ScrimInsetsFrameLayout\n android:id=\"@+id/navigation_drawer\"\n android:layout_width=\"@dimen/navdrawer_width\"\n android:layout_height=\"match_parent\"\n android:layout_gravity=\"start\"\n android:fitsSystemWindows=\"true\"/>\n</android.support.v4.widget.DrawerLayout>\n\n\nGives this result:\nAs you can see, the status bar seems to be completely absent (maybe it's correct?) since the content is drawn full screen. When the app starts I can see the toolbar is drawn (rendered without the staus bar padding, thus messing up with the system icons) and then suddenly gets overlayed by the map content. I'm currently running Android 4.4.4 but it's the same on the emulator with Android 5.0.\n\n\n\nIn another stackoverflow question it was suggested to put a root LinearLayout with the Toolbar and the DrawerLayout, but would result in strange results, such as correctly rendering the toolbar but with the status bar (with solid non-transparent background) under it. I've tried also to use a FrameLayout as root, with poor results.\n\nAny advice on how to handle this problem?" ]

[ "How to avoid using shell=True in the python subprocess module when faced with memory constraints", "As part of a larger python script I am writing that is associated with genome sequence alignment, I would like to be able to record the number of lines in a gzipped file provided by the user. As far as I can tell, the following bash command is the simplest way to accomplish such a task:\nzcat file/path.gz | wc -l\n\nUsing the python subprocess module, (and avoiding shell=True) I use the following code in Python to accomplish the same task:\nzcatInput = subprocess.check_output(("zcat", filePathFromUser), encoding = "utf-8")\nresult = subprocess.check_output(("wc", "-l"), encoding = "utf-8", input = zcatInput)\n\nHowever, some of the files I am trying to do this with are hundreds of millions of lines long once unzipped, so storing the result of the zcat command uses a ridiculous amount of memory (more than my computer has available).\nMy question is this: What is the best way to circumvent this problem without using shell=True? (From what I've read online, shell=True appears to be very dangerous and should be avoided at all costs).\nAdditionally: Is this a scenario where the use of shell=True with properly sanitized inputs is acceptable, or do the dangers of shell=true go even further than I am aware of?\nIn my efforts to answer these questions, I've come up with two possible solutions:\n\nCreate a simple bash script to perform the zcat operation on a given file and pipe it to wc -l. Then, call that script using the subprocess module (and shell=False, hooray!)\nUse the shell=True argument with the subprocess module to just run the bash command with '|', but sanitize the user input using shlex.quote().\n\nI suppose you could also boil down my question to something more concrete by asking: What is the difference (if any) between the two above approaches in terms of security and memory constraints, and is there a preferable "option 3" that I am missing?" ]
