--exec-flags Cache,DRAM show addresses and sizes, but sometimes I just need to see the actual data being sent.
I know that this might produce large logs, but that is fine as I'm restricting my area of interest well via --debug-start and -m/--debug-break (used a hack here to just finish the simulation at a tick).
https://gem5-users.gem5.narkive.com/VUAhxc7J/how-can-i-trace-data-of-cache mentions using CommMonitor. It is a bit annoying to have to modify the run script, but that's also a valid solution. It would be good to give a minimal example here that patches say se.py to add it and how to view its output.
I also have DPRINTF patch which seems to help and I'll try to publish. Here's a sketch:
## -385,14 +386,17 ## void
Packet::print(std::ostream &o, const int verbosity,
const std::string &prefix) const
{
- ccprintf(o, "%s%s [%x:%x]%s%s%s%s%s%s", prefix, cmdString(),
+ ccprintf(o, "%s%s [%x:%x]%s%s%s%s%s%s D=%llx", prefix, cmdString(),
getAddr(), getAddr() + getSize() - 1,
req->isSecure() ? " (s)" : "",
req->isInstFetch() ? " IF" : "",
req->isUncacheable() ? " UC" : "",
isExpressSnoop() ? " ES" : "",
req->isToPOC() ? " PoC" : "",
- req->isToPOU() ? " PoU" : "");
+ req->isToPOU() ? " PoU" : "",
+ flags.isSet(STATIC_DATA|DYNAMIC_DATA) ?
+ mem2hex_string(getConstPtr<const char>(), getSize())
+ : "");
}
and then implement mem2hex_string as shown at: C++ read binary file and convert to hex
Edit: I managed to add a CommMonitor by hacking se.py, but I could not see any memory value output in any files nor in its code, the only thing I could see was new stats being added, so not sure that can help at all.

Is there a way to create custom variables inside a VScode snippet?
I have these kind of snippets where I create a singleton, based on the name of a file and a folder.
Here's the snippet:
"Service": {
"prefix": "singletonByPath",
"body": [
"class ${TM_DIRECTORY/.*[^\\w]([a-z])(\\w+)$/${1:/upcase}$2/g}${TM_FILENAME_BASE/([a-z])(\\w+)/${1:/upcase}$2/g} {",
" $0",
"}",
"",
"export const ${TM_DIRECTORY/.*[^\\w]([a-z])(\\w+)$/${1:/downcase}$2/g}${TM_FILENAME_BASE/([a-z])(\\w+)/${1:/upcase}$2/g} = new ${TM_DIRECTORY/.*[^\\w]([a-z])(\\w+)$/${1:/upcase}$2/g}${TM_FILENAME_BASE/([a-z])(\\w+)/${1:/upcase}$2/g}();",
""
],
"description": "Create an exported singleton instance and a class based on the filename and path"
},
So, when the snippet is triggered in a path like: '..../customers/service.ts' You will have this result:
class CustomersService {
}
export const customersService = new CustomersService();
The problem is that I have duplications of long hard to read regexes, and I would like to extract them to variables (or mirrors without tab stops).
I would even prefer having these variables in a "snippet-global location" so that I can use them in multiple snippets.
Is it possible to somehow reduce these duplications?
There are a couple of things you can do to simplify your snippet. There is no built-in way to save "variables" of pre-defined snippet parts.
Here though is a simplification of your code:
"Service": {
"prefix": "singletonByPath",
"body": [
// "class ${TM_DIRECTORY/.*[^\\w]([a-z])(\\w+)$/${1:/upcase}$2/g}${TM_FILENAME_BASE/([a-z])(\\w+)/${1:/upcase}$2/g} {",
"class ${1:${TM_DIRECTORY/.*[^\\w]([a-z])(\\w+)$/${1:/upcase}$2/g}}${2:${TM_FILENAME_BASE/([a-z])(\\w+)/${1:/upcase}$2/g}} {",
-- --
" $0",
"}",
"",
// "export const ${TM_DIRECTORY/.*[^\\w]([a-z])(\\w+)$/${1:/downcase}$2/g}${TM_FILENAME_BASE/([a-z])(\\w+)/${1:/upcase}$2/g} = new ${TM_DIRECTORY/.*[^\\w]([a-z])(\\w+)$/${1:/upcase}$2/g}${TM_FILENAME_BASE/([a-z])(\\w+)/${1:/upcase}$2/g}();",
"export const ${1/(\\w+)/${1:/downcase}/}$2 = new $1$2();",
""
],
"description": "Create an exported singleton instance and a class based on the filename and path"
}
Note the use of $1:${TM_DIRECTORY...} and likewise ${2:${TM_FILENAME_BASE...}
This effectively sets $1 to the result of the TM_DIRECTORY transform and $2 to the result of the TM_FILENAME_BASE transform and those "variables" can be used elsewhere in the snippet by just referring to $1 and $2.
Those "variables" can even be transformed themselves as in the ${1/(\\w+)/${1:/downcase}/} transform in the last line.
The last line of your snippet then becomes simply:
"export const ${1/(\\w+)/${1:/downcase}/}$2 = new $1$2();",
You will have to tab a couple of times because those "variables" are now tabstops, and the last transform won't be completed until you do tabstop past it, but that is a small price to pay for such a simplification.
There are other simplifications to your snippet that aren't "variable-related":
"body": [
"class ${1:${TM_DIRECTORY/.*[\\/\\\\](.*)/${1:/capitalize}/}}${2:${TM_FILENAME_BASE/(.*)/${1:/capitalize}/}} {",
" $0",
"}",
"",
"export const ${1/(\\w+)/${1:/downcase}/g}$2 = new $1$2();",
""
],
You can use the capitalize transform. Also note that this last body works for Windows and linux path separators.
I'm writing a program that should output a meta-info (size, permissions to execute / read / write, time of last modification) of all files from the specified directory.
I received information about all the information, except the rights to execute / read / write.
I tried to get this info using PosixFilePermissions, but when added to the List I get Exception in thread "main" java.lang.UnsupportedOperationException.
Maybe you should use some other library? Or did I make a mistake somewhere? I would be grateful for any advice!
fun long(path:Path) : MutableList<String> {
var listOfFiles = mutableListOf<String>()
val files = File("$path").listFiles()
var attr: BasicFileAttributes
Arrays.sort(files, NameFileComparator.NAME_COMPARATOR)
files.forEach {
if (it.isFile) {
attr = Files.readAttributes<BasicFileAttributes>(it.toPath(), BasicFileAttributes::class.java)
listOfFiles.add("${it.name} ${attr.size()} ${attr.lastModifiedTime()}" +
" ${PosixFilePermissions.toString(Files.getPosixFilePermissions(it.toPath()))}")
}
else listOfFiles.add("dir ${it.name}")
}
return listOfFiles
}
PosixFilePermissions are only usable for POSIX-compatible file systems (Linux etc.).
For a Windows system, the permissions have to be accessed directly:
file.canRead()
file.canWrite()
file.canExecute()
I am using Eclipse IProgressMonitor to monitor the progress of a task. There are four steps, and I write the following code.
int totalWork = 100;
String message = "Compiling " + inputFile.getName();
monitor.beginTask(message, totalWork);
monitor.subTask(message + " - first pass");
...// Work
monitor.worked(25);
if (monitor.isCanceled())
return;
monitor.subTask(message + " - invoking");
...// work
monitor.worked(25);
if (monitor.isCanceled())
return;
monitor.subTask(message + " - second pass");
...// Work
monitor.worked(25);
if (monitor.isCanceled())
return;
monitor.subTask(message + " - final pass");
...// Work
monitor.worked(25);
if (monitor.isCanceled())
return;
monitor.done();
As I have total work 100, and each step increase it by 25, I am hoping to see the progress bar show 25% 50% etc. and increase. However the progress bar stops at some number (33%, 38%, 20%, kind of random on different machines) and does not change until the entire job is done. The task name changes though. I read the JavaDoc for this API and follow the way it suggests (I think). Can anyone help tell me where I went wrong?
I am new to noflo and looking at examples in order to explore it. The spreadsheet example looked interesting but I couldn't make it run. First, it takes some time and manual debugging to identify missing components, not a big deal and I believe will be improved in the future, for now the error message I get is
return process.component.outPorts[port].attach(socket);
^
TypeError: undefined is not a function
Apparently, before this isAddressable() was also undefined. Checked with this SO issue but I don't have any noflo 0.4 as a dependency anywhere. Spent some time to debug it but seemingly stuck at it, decided to post to SO.
The question is, what are the correct steps to run the spreadsheet example?
For reproduction, here is what I have done:
0) install the following components
noflo-adapters
noflo-core
noflo-couchdb
noflo-filesystem
noflo-groups
noflo-objects
noflo-packets
noflo-strings
noflo-tika
noflo-xml
i) edit spreadsheet/parse.fbp, because first error was
throw new Error("No outport '" + port + "' defined in process " + proc
^
Error: No outport 'error' defined in process Read (Read() ERROR -> IN Display())
apparently couchdb ReadDocument component does not provide Error outport. therefore replaced ReadDocument with ReadFile.
18c18
< 'tika-app-0.9.jar' -> TIKA Read(ReadDocument)
---
> 'tika-app-0.9.jar' -> TIKA Read(ReadFile)
ii) at this point, received the following:
if (process.component.outPorts[port].isAddressable()) {
^
TypeError: undefined is not a function
and improvised a stunt by checking if isAddressable is defined at this location of code:
## -259,9 +261,11 ##
throw new Error("No outport '" + port + "' defined in process " + process.id + " (" + (socket.getId()) + ")");
return;
}
- if (process.component.outPorts[port].isAddressable()) {
+ if (process.component.outPorts[port].isAddressable && process.component.outPorts[port].isAddressable()) {
return process.component.outPorts[port].attach(socket, index);
}
return process.component.outPorts[port].attach(socket);
};
and either way fails. Again, the question is What are the correct steps to run the spreadsheet example?
Thanks in advance.
I am attempting to set up a small test environment (homelab) using CentOS 6.6, Rancid 3.1, Looking Glass, and some Cisco Switches/Routers, with httpd acting as the handler. I have picked up a little perl by means of this endeavor, but python (more 2 than 3) is my background. Right now, everything on the rancid side of things works without issue: bin/clogin successfully logs into all of the equipment in the router.db file, and logging of the configs is working as expected. All switches/routers to be accessed are available and online, verified by ssh connection to devices as well as using bin/clogin.
Right now, I have placed the lg.cgi and lgform.cgi files into var/www/cgi-bin/ which allows the forms to be run as cgi scripts. I had to modify the files to split on ';' instead of ':' due to the change in the .db file in Rancid 3.1:#record = split('\:', $_); was replaced with: #record = split('\;', $_); etc. Once that change was made, I was able to load the lgform.cgi with the proper router.db parsing. At this point, it seemed like everything should be good to go. When I attempt to ping from one of those devices out to 8.8.8.8, the file correctly redirects to lg.cgi, and the page loads, but with
main is unavailable. Try again later.
as the error, where 'main' is the router hostname. Using this output, I was able to find the function responsible for this output. Here it is before I added anything:
sub DoRsh
{
my ($router, $mfg, $cmd, $arg) = #_;
my($ctime) = time();
my($val);
my($lckobj) = LockFile::Simple->make(-delay => $lock_int,
-max => $max_lock_wait, -hold => $max_lock_hold);
if ($pingcmd =~ /\d$/) {
`$pingcmd $router`;
} else {
`$pingcmd $router 56 1`;
}
if ($?) {
print "$router is unreachable. Try again later.\n";
return(-1);
}
if ($LG_SINGLE) {
if (! $lckobj->lock("$cache_dir/$router")) {
print "$router is busy. Try again later.\n";
return(-1);
}
}
$val = &DoCmd($router, $mfg, $cmd, $arg);
if ($LG_SINGLE) {
$lckobj->unlock("$cache_dir/$router");
}
return($val);
}
In order to dig in a little deeper, I peppered that function with several print statements. Here is the modified function, followed by the output from the loaded lg.cgi page:
sub DoRsh
{
my ($router, $mfg, $cmd, $arg) = #_;
my($ctime) = time();
my($val);
my($lckobj) = LockFile::Simple->make(-delay => $lock_int,
-max => $max_lock_wait, -hold => $max_lock_hold);
if ($pingcmd =~ /\d$/) {
`$pingcmd $router`;
} else {
`$pingcmd $router 56 1`;
}
print "About to test the ($?) branch.\n";
print "Also who is the remote_user?:' $remote_user'\n";
print "What about the ENV{REMOTE_USER} '$ENV{REMOTE_USER}'\n";
print "Here is the ENV{HOME}: '$ENV{HOME}'\n";
if ($?) {
print "$lckobj is the lock object.\n";
print "#_ something else to look at.\n";
print "$? whatever this is suppose to be....\n";
print "Some variables:\n";
print "$mfg is the mfg.\n";
print "$cmd was the command passed in with $arg as the argument.\n";
print "$pingcmd $router\n";
print "$cloginrc - Is the cloginrc pointing correctly?\n";
print "$LG_SINGLE the next value to be tested.\n";
print "$router is unreachable. Try again later.\n";
return(-1);
}
if ($LG_SINGLE) {
if (! $lckobj->lock("$cache_dir/$router")) {
print "$router is busy. Try again later.\n";
return(-1);
}
}
$val = &DoCmd($router, $mfg, $cmd, $arg);
if ($LG_SINGLE) {
$lckobj->unlock("$cache_dir/$router");
}
return($val);
}
OUTPUT:
About to test the (512) branch.
Also who is the remote_user?:' '
What about the ENV{REMOTE_USER} ''
Here is the ENV{HOME}: '.'
LockFile::Simple=HASH(0x1a13650) is the lock object.
main cisco ping 8.8.8.8 something else to look at.
512 whatever this is suppose to be....
Some variables:
cisco is the mfg.
ping was the command passed in with 8.8.8.8 as the argument.
/bin/ping -c 1 main
./.cloginrc - Is the cloginrc pointing correctly?
1 the next value to be tested.
main is unreachable. Try again later.
I can provide the code for when DoRsh is called, if necessary, but it looks mostly like this:&DoRsh($router, $mfg, $cmd, $arg);.
From what I can tell the '$?' special variable (or at least according to
this reference it is a special var) is returning the 512 value, which is causing that fork to test true. The problem is I don't know what that 512 means, nor where it is coming from. Using the ref site's description ("The status returned by the last pipe close, backtick (``) command, or system operator.") and the formation of the conditional tree above, I can see that it is some error of some kind, but I don't know how else to proceed with this inspection. I'm wondering if maybe it is in response to some permission issue, since the remote_user variable is null, when I didn't expect it to be. Any guidance anyone may be able to provide would be helpful. Furthermore, if there is any information that I may have skipped over, that I didn't think to include, or that may prove helpful, please ask, and I will provide to the best of my ability
May be you put in something like
my $pingret=$pingcmd ...;
print 'Ping result was:'.$pingret;
And check the returned strings?
