How to exclude a directory in Stream mapping in p4v - version-control

I'm using the visual client for perforce and I want to exclude a directory from the workspace. Before streams, I would just navigate to my workspace, find the folder in the tree, and exclude it (and I've found this solution in a number of other related questions I've found). However, now that I am using a stream, it won't let me do this, i have to edit the stream mapping apparently.
So I tried to add this line to the remapped box when editing the stream:
-//NumberPlus/current/Library/... //nplus-mainline/current/Library/
However I just get an error:
Error in stream specification.
Error detected at line 24
Null directory (//) not allowed in '-//NumberPlus/current/Library/...'.
EDIT: I'm in Windows 8.1, for clarification.

If the folder you want to exclude is specific to your machine, setting P4IGNORE locally is the easiest way to exclude it from being added to the depot.
http://www.perforce.com/blog/120214/new-20121-p4ignore
You'd set P4IGNORE to some name like "p4ignore.txt", create a file with that name, and add "Libraries" to it -- subsequent "p4 add" commands will skip over paths found in the P4IGNORE file, so those files will never get added to the depot.
If this is something that's going to be common to all workspaces of this stream (e.g. it's a build artifact that everyone is going to generate and nobody is supposed to check in), what you want to do is add an "exclude" to the stream's Paths (this will exclude it from both branch views and client views generated by that stream). E.g.:
Paths:
share ...
exclude Libraries/...
The "exclude Libraries/..." is basically the same thing as the exclusion line you would add to the client view, except you specify it as a relative path, you don't need to specify both sides of the mapping, and the "-" is implied by the "exclude" type. The "remap" type is if you want to keep those files but in a different depot location, which doesn't sound applicable here.
More information on defining stream views:
http://www.perforce.com/perforce/doc.current/manuals/p4v/streams_views.html

You can't just edit the mappings for your client workspace if it is switched to a particular stream. The whole point of streams is that your workspace mapping is directly generated from the stream definition. So that's a feature.
It's not totally clear whether
you don't want the directory in the stream at all, or
it's valid to have the directory in the stream, but you don't want to sync it to your workstation, or
you want the directory sync'd to your workstation, but you want the directory to have different contents (say, from some other stream which has a different version of the library.
However, for all of these situations, I suspect the best path forward is to define a new child stream of your current stream.
You will want to define the path mappings using the "share", "exclude", "isolate", and "import" mapping types.
For example, if you just didn't want the Library/... directory at all, you'd "exclude" it from your parent.
Then that stream simply won't have that directory, and it (of course) won't be on your workstation when you sync to the stream, either.
If you wanted to have a different copy of the code in the Library/... directory, so that it became a point of intentional divergence from the parent, you'd "isolate" it from your parent to submit your own custom version, or "import" it from another stream to use that stream's Library/... directory instead.
In either case, the directory would be part of the stream, and would be sync'd to your workstation, but the contents of that directory would differ from the contents that are used in the parent stream (the exact way in which they'd differ is under your control, as you define the stream accordingly).
Documentation and some examples are here: http://www.perforce.com/perforce/doc.current/manuals/p4v/streams_views.html
and here:
http://www.perforce.com/sites/default/files/pdf/Streams-ebook.pdf

I believe I have solved this. To be clear, I wanted the folder to be completely ignored by version control. I'm using p4connect with Unity and it keeps wanting to include unnecessary stuff in my depot.
All I had to do was add this line to my parent stream in the Paths box:
exclude current/Library/...

Migrating from itext2 to itext7

Years ago, I wrote a small app in itext2 to gather reports on a weekly basis and concatenate them into one PDF. The app used com.lowagie.text.pdf.PdfCopy to copy and merge the PDFs. And it worked fine. Performed exactly as expected.
A few weeks ago I looked into migrating the application to itex7. To that end, I used the copyPagesTo method of com.itextpdf.kernel.pdf.PdfDocument. When run on the same file set, this produces warnings like:
WARN PdfNameTree - Name "section.1" already exists in the name tree; old value will be replaced by the new one.
When I click on the link to "section.1" in the first document of the merged PDF, I am taken to "section.1" of the last document. Not what I expected and not what happens when using the itext2 app. In the PDF's produced by itext2, if I click on the link to "section.1" of the first document in the combined PDF, I am taken to section 1 of the first document.
There is a hint in Javadocs for copyPagesTo saying
If outlines destination names are the same in different documents, all
such outlines will lead to a single location in the resultant
document. In this case iText will log a warning. This can be avoided
by renaming destinations names in the source document.
There is however, no explanation of how this should be done. I find it odd that this should be necessary in itext7, although it wasn't in itext2.
Is there a simple way to get around his problem?
I've also tried the Sejda desktop app and it produces correct results, but I would prefer to automate the process through a batch script.
My guess is iText 2 didn't even know it might be a problem.
If iText can't deduplicate destination names, the procedure is roughly:
Follow /Catalog -> /Names -> /Dests in each document to find the destination name tree.
Deduplicate the names, by adding suffixes. Remember that a name with a suffix added might be equal to an existing name in the same or another document. Be careful!
Now you can rewrite the destination name trees. Since you have only used suffixes, you can do this in place - the lexicographic ordering of the names is unaltered so the search tree structure is not broken.
Now, rewrite destination links in each PDF for the new names. For example any dictionary entry with key /Dest, or any /D in a /GoTo action.
Now, after all this preprocessing, the files will merge without name clashes.
(I know all this because I've just implemented it for my own PDF software. It's slightly hairy stuff, but not intractable.)
If you like, I can provide a devel version of cpdf with this functionality, if you would like to test it.

"Two output file names resolved to the same output path" error when nesting more than one .resx file within form in .NET application

I have a Windows Forms .NET application in Visual Studio. Making a form "Localizable" adds a Form1.resx file nested below the form. I also want to add a separate .resx file for each form (Form1Resources.resx). This is used for custom form-specific resources, e.g. messages generated using the code behind.
This is set up as follows:
It would be tidier to nest the custom .resx file beneath the form (see this question for details about nest how to do this), as follows:
However, this results in the following error when I build the application:
Two output file names resolved to the same output path:
"obj\Debug\WindowsFormsApp1.Form1.resources" WindowsFormsApp1
I'm guessing that MSBuild uses some logic to find nested .resx files and generate .resources file based on its parent. Is there any way that this can be resolved?
Note that it is not possible to add custom messages to the Form1.resx file - this is for design-specific resources only and any resources that you add get overwritten when you save changes in design mode.
The error comes from the GenerateResource task because the 2 resx files (EmbeddedResource items in msbuild) passed both have the same ManifestResourceName metadata value. That values gets created by the CreateManifestResourceNames task and assumingly when it sees an EmbeddedResource which has the DependentUpon metadata set (to Form1.cs in your case) it always generates something of the form '$(RootNamespace).%(DependentUpon)': both your resx files end up with WindowsFormsApp1.Form1 as ManifestResourceName. Which could arguably be treated as the reason why having all resx files under Form1 is not tidier: it's not meant for it, requires extra fiddling, moreover it could be confusing for others since they'd typcially expect to contain the resx fils placed beneath a form to contain what it always does.
Anyway: there's at least 2 ways to work around this:
there's a Target called CreateCustomManifestResourceNames which is meant to be used for custom ManifestResourceName creation. A bit too much work for your case probably, just mentioning it for completeness
manually declare a ManifestResourceName yourself which doesn't clash with the other(s); if the metadata is already present it won't get overwritten by
Generic code sample:
<EmbeddedResource Include="Form1Resources.resx">
<DependentUpon>Form1.cs</DependentUpon>
<ManifestResourceName>$(RootNamespace).%(FileName)</ManifestResourceName>
...
</EmbeddedResource>

Reading files from Apache Spark textFileStream

I'm trying to read/monitor txt files from a Hadoop file system directory. But I've noticed all txt files inside this directory are directories themselves as showed in this example bellow:
/crawlerOutput/b6b95b75148cdac44cd55d93fe2bbaa76aa5cccecf3d723c5e47d361b28663be-1427922269.txt/_SUCCESS
/crawlerOutput/b6b95b75148cdac44cd55d93fe2bbaa76aa5cccecf3d723c5e47d361b28663be-1427922269.txt/part-00000
/crawlerOutput/b6b95b75148cdac44cd55d93fe2bbaa76aa5cccecf3d723c5e47d361b28663be-1427922269.txt/part-00001
I'd want read all the data inside the part's files. I'm trying to use the following code as showed in this snippet:
val testData = ssc.textFileStream("/crawlerOutput/*/*")
But, unfortunately it said it doesn't exist /crawlerOutput/*/*. Doesn't textFileStream accept wildcards? What should I do to solve this problem?
The textFileStream() is just a wrapper for fileStream() and does not support subdirectories (see https://spark.apache.org/docs/1.3.0/streaming-programming-guide.html).
You would need to list the specific directories to monitor. If you need to detect new directories a StreamingListener could be used to check then stop streaming context and restart with new values.
Just thinking out loud.. If you intend to process each subdirectory once and just want to detect these new directories then potentially key off another location that may contain job info or a file token that once present could be consumed in the streaming context and call the appropriate textFile() to ingest the new path.

Merging doxygen modules

I have a large amount of code that I'm running doxygen against. To improve performance I'm trying to break it into modules and merge the result into one set of docs. I thought tag files would do the trick, but either I have it configured wrong or I'm misunderstanding how it works.
The directories are laid out:
root +
|-src+
| |-a
|
|-doc+
|-a.dox
|-main.dox
|-main.md
|-output+
|-a+
| |-html
|-main+
|-html
In addition to 'a' there are other peer directories but am starting with one.
a.dox generates output and a tag file into root/doc/output
OUTPUT_DIRECTORY=output/a
GENERATE_TAGFILE = output/a/a.tag
INPUT=../src/a
main.dox just inputs the markdown file that has a mainpage tag and refers to the other projects tag file.
OUTPUT_DIRECTORY=output/main
INPUT = main.md
TAGFILES=output/a/a.tag=output/a/html
Should this merge or link all the docs under main where I can browse 'a' globals, modules, pages, etc? Or does this only generate links to 'a' if I explicitly cross-reference a documented entity in 'a' from inside of 'main'?
If this should work, any thoughts on where my syntax is incorrect? I've tried various ways to define TAGFILES, is the output directory relative to the main.dox file? To the a.tag file? Or to the a/html directory?
If I'm off base an TAGFILES don't work this way, is there another way to merge sets of doxygen directories into one?
Thanks.
I suggest you read this topic on how I recommend to use tag files and the conditions that should apply: https://stackoverflow.com/a/8247993/784672
To answer your first question: doxygen will in general not merge the various index files together (then no performance would be gained). Although for a part you can still get external members in the index by setting ALLEXTERNALS to YES.
Doxygen will (auto)link symbols from other sources imported via a tag file. So in general you should divide your code into more or less self-contained modules/components/libraries, and if one such module depends on another, then import its tag file so that doxygen can link to the other documentation set. If you run doxygen twice (once for the tag file and once for the documentation) you can also resolve cyclic dependencies if you have them.
In my case I made a custom index page with links to all modules, and made a custom entry in the menu of each generated page that linked back to this index (see http://www.doxygen.nl/manual/customize.html#layout) how to add a user defined entry to the navigation menu/tree.

Is it possible to use variables in a ClearCase config spec?

For example, instead of writing the following:
element * .../my_branch_01/LATEST
element * .../base_branch/LATEST -mkbranch my_branch_01
I would want to write something like this:
MY_BRANCH=my_branch_01
element * .../%MY_BRANCH%/LATEST
element * .../base_branch/LATEST -mkbranch %MY_BRANCH%
Is this even possible? What is the correct syntax?
The only native way to do this in ClearCase is to use attribute within a config-spec.
According to the version selector rules, you can make a "selection by query" rule, based for instance on an attribute:
element * ...{MY_ATTRIBUTE_NAME=="aValue"}
would select the LATEST version on any branch with an attribute 'MY_ATTRIBUTE_NAME' with 'aValue' in it.
That mean you need to change the attribute value on the old branch, put it on the new branch, 'cleartool setcs' your view again, and you should have a new content based on a new version selection.
Not very straight forward, but it could work, except for the mkbranch part (which needs a fixed name).
Regarding GeekCyclist's answer, a few comments:
The solution to include a common config spec can work for Base ClearCase solution, but:
need to be in a share available by all concerned developer
the setcs is indeed necessary to Ccuses the view_server to flush its caches and reevaluate the current config spec, which is stored in file config_spec in the view storage directory. This includes:
Evaluating time rules with nonabsolute specifications (for example, now, Tuesday)
Reevaluating –config rules, possibly selecting different derived objects than previously
Re-reading files named in include rules
all the other developers need to be notified when the common included config spec file changes (there is no native notification included in ClearCase)
If you need to have one "environment" (i.e. one "view" or workspace) with a variable content (depending on a different branch), you need to define a symbolic link (or a windows subst) pointing to different views (each with their own config spec)
That way, you only have to change the link (or the path subst'ed) in order to change the config spec associated with a given fixed path.
It's been a while since I worked in ClearCase (we switched to Subversion), but if I recall correctly there is no way to do this native to ClearCase.
You could use or write a script generator that would create your spec file and then include that in the actual spec:
element * CHECKEDOUT
include scripted_file_output
Then run
cleartool setcs -current
The problem with this approach is that I believe the include spec would need to be regenerated and the cleartool setcs run whenever you change the value of MY_BRANCH.
