Fille::stat returns defined on <control> character 0x00 - perl - feature or bug? -


# perl 5, version 22, subversion 1 (v5.22.1) # built x86_64-linux-gnu-thread-multi

use file::stat; $wchar   = chr 0; $unicode = sprintf 'u+%06x', ord $wchar; $file    = './'.$wchar; $sb      = stat($file);  if($sb){     printf "file %s, size %s, perm %04o, mtime %s\n",     $file, $sb->size, $sb->mode & 07777,     scalar localtime $sb->mtime;     printf "unicode $unicode\n", }

----- gives me.. ----

file ./^@, size 4096, perm 0775, mtime mon aug 14 20:34:21 2017 unicode u+000000

i'm bit baffled. suggestions why happen. feature or bug?

stat passes string os untouched. os expects nul-terminated string, sees ./ when pass ./␀.

before 5.20, used case open well. returns error enoent instead.

$ perlbrew use 5.20.0t  $ ls -1  $ perl -e'open $fh, ">", "abc\0def" or die $!;' no such file or directory @ -e line 1.  $ perlbrew use 5.18.2t  $ ls -1  $ perl -e'open $fh, ">", "abc\0def" or die $!;'  $ ls -1 abc

i consider lack of consistency bug.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
