I'm having an odd issue with residual locks on aprx files when I interact with them via iteration through a list of names. Specifically, the first file that I reference ends up with a hanging lock but the others do not.
I've queried with locals(), and Python does not think it has any hanging references left to an open arcpy object. Here is the code (with paths and files anonymized):
objDict = locals().copy()
prjPath ="C:/Pydata/thisproject/testdir/"
prjs = ["project1.aprx", "project2.aprx","project3.aprx", "project4.aprx"]
shpPath = "C:/Pydata/thisproject/subproject/outputs/"
boundaryPath = "C:/Pydata/thisproject/GIScovs/boundaryshapefile/"
mths = ["jan","feb","mar","apr","may","jun","jul","aug","sep","oct","nov","dec"]
stages = ["C4","C3","C2","C1"]
for idx, prjName in enumerate(prjs):
fullname = prjPath + prjName
ArcProject = arcpy.mp.ArcGISProject(fullname) #open the required project
workingmap = ArcProject.listMaps()[0] # open map to add shapefiles
stg = stages[idx] #get the relevant stage
#by iterating the month list in reverse order, placement within the project aligns with desired pattern
for mth in reversed(mths):
shpStr = stg + "_" + mth + "_val"
shpName = shpPath + shpStr
if arcpy.Exists(shpName): # make sure the desired file exists before adding in order to trap errors related to sparse data
workingmap.addDataFromPath(shpName)
else:
print("shape " + shpName + " not found")
#next add the desired boundary file:
#this is the name of the desired layer
boundaryLyrPath = "C:/Pydata/GIScovs/boundary.lyrx"
boundaryLyr = arcpy.mp.LayerFile(boundaryLyrPath)
workingmap.addLayer(boundaryLyr)
#save the project
ArcProject.save()
#DELETE ALL REFERENCES TO ARCPY OBJECTS
del boundaryLyr
del workingmap
del ArcProject
newObjDict = locals().copy()
for listitem in newObjDict:
#print active objects added by this code block
if listitem not in objDict:
print(listitem)
The printout from comparing the dictionaries gives:
prjPath
prjs
shpPath
boundaryPath
mths
stages
idx
stg
mth
shpStr
shpName
boundaryLyrPath
All of these are pure Python objects, none are ArcPy references.
When I run this, "project1.aprx" (the first item in the projects list) ends up with a hanging lock such that in the next block of code that I run it cannot be saved (it's read-only). The others do not have the same issue. I'm at a loss, but maybe I'm missing something obvious?
Thanks in advance for any thoughts.
