My files are on disk and they are regular text files named file_1 file_2 file_3 file_4 and file_5 with extension .saam The separator is sep='' (ie, white space) I want to append 'XFile' at the end of those files. XFile is also on disk. file.append("file_1.saam", "XFile.saam"); file.append("file_2.saam", "XFile.saam")... works but it

Hi, I need help :o( I want that my function saves result files in a for()-loop while it runs automatically. the filenames must be saved like: file_1 -> for 1. result file_2 -> for 2. result file_3 -> for 3. result and . . . file_n -> for n. result the file names are the same identified by _1, _2

I have a form with multiple file upload fields (1-10), of which 2-10 are optional. So i need to cycle thru all file fields and pick only those that have a file attached. Selecting only one file in the form, the paramters look simple: "image"=>{"file_1"=>#<File:/tmp/CGI344.4>, "file_2"=>"", "file_3"=>""}, so I

Dear all, If the question is too easy, please forgive me since I am only few weeks old in R. I have worked on this question a few days and still cannot figure it out. Here I have a folder with more than 50 tab-delimited files. Each file has a few hundreds of thousands rows/subjects, and the number of columns/variables of each file varies.The 1st row consists of all the variable names. Now I

Hi, I have tried to make a recursive scp from a ReliantUNIX machine to an other UNIX machine and got an infinite loop on the source machine. A "normal" scp works well. Also strange is, that the first two letters of the directory respectively file name are missing in the output below. The destination machine produces a directory structure with growing subdirectory names. Below you can

Hi - I have a list (call it 'mylist') with the following elements: (i) a function (call it 'myfunc' and expressed as 'mylist$myfunc') and (ii) a variable (call it 'myvar' and expressed as 'mylist$myvar'). Since I use mylist as a pseudo-class (I assign mylist to multiple different R objects), I would like to access the mylist R object from within the

Hi I am using SanitizerCoverage feature supported by clang to get the basicblock coverage. my tested binaries are spec cpu2006. I compiled the binary with the option COPTIMIZE = -O0 -fsanitize=address -fsanitize-coverage=bb -flto -fno-strict-aliasing -std=gnu89 -gdwarf-3 After the compiling process is end. I run the 400.perlbench. with the command ASAN_OPTIONS=coverage=1 ./perlbench.

Hello, samba-users, I am using Amanda to backup WinNT-shares. Amanda uses smbclient to generate smbtar-archives which it then writes to tape. As you all know there are various files on Windows-system-partitions that don?t need to be on backup. For example stuff like pagefile.sys System Volume Information hiberfil.sys and the registry files. So there is a need to exclude files from getting

hi all, i tried to encode a .yuv file with the encoder_example.c but it give an error message as follows ./encoder_example -v 1 file_1.yuv > file_1.ogg Input file file_1.yuv is neither a WAV nor YUV4MPEG2 file. so the error message is understandable for anyone. when this file is play with mplayer it shows as follow

Hi If so, is it able to disable this check.

At 167457 on x86_64-apple-darwin12, I am seeing a slew of AddressSanitizer failures due to unresolved symbols such as...

Hi Alex Thanks for your email. But it seems not work. I removed the -fsanitize=address flag. The global buffer overflow message doesn't show. However, no *.sancov file is created after I run perlbench. Thus, I could not get the BB coverage. Do you have any ideas? Many Thanks Regards Muhui Alexander Potapenko <glider at google.com> 于2018年9月5日周三 下午7:14写道： > Hi Muhui, > > If

Hello, We've just got a bug report from Mozilla folks about AddressSanitizer false positive with -O2. Turns out there is a conflict between load widening and AddressSanitizer. Simple reproducer: % cat load_widening.c && echo ========= && clang -O2 -c load_widening.c -flto && llvm-dis load_widening.o && cat load_widening.o.ll void init(char *); int foo() {

Dear R developers, I've got an information from Prof. Ripley regarding a bug found with AdressSanitizer in one of our packages. It is now fixed, thank you for this information. Now, I would like to run AddressSanitizer myself before submitting the patched package to CRAN. Is there a recommendation of a suitable Linux distribution with gcc 4.8, ideally an ISO image or (even better) a

Hello, LLVM developers I would like to ask about the changes in the "nonpublic" AddressSanitizer flags in llvm 3.5. Prior to 3.5 (namely, on 3.4.2) there was a compile-time flag to control the shadow offset. For example, one could do the following to force the large offset: -mllvm -asan-mapping-offset-log=44 Now, it has been removed and on x86_64 linux the smaller offset is always

I've finished my initial set of patches to make 32-byte shadow granularity work on x86. Here is a summary of the changes from last week: - As discussed, I added a full redzone after every stack variable. - We discussed adding a -fsanitize-address-granularity=N flag, but I found the following existing flag has been sufficient for my purposes: -asan-mapping-scale N. If anyone thinks I
