Rather than reading the size everywhere it is needed, get it when the tag is read, if it exists.
This simplifies logic around consuming the data when not needed. There are more use cases for this coming up.
The vast majority of Strings are never modified so for most cases allocate memory for the string with the object. This results in one allocation in most cases instead of two. Use strNew() if strCat*() functions are needed.
Update varNewStr() in the same way since String Variants can never be modified. This results in one allocation in all cases instead of three. Also update varNewStrZ() to use STR() instead of strNewZ() to save two more allocations.
A stanza name like global_stanza was not allowed because the code was not selective enough about how a global section should be formatted.
Update the config parser to correctly recognize global sections.
Remove the hardcoded storage helpers from storageRepoGet() except for the the built-in Posix helper and the special remote helper.
The goal is to make storage driver development a bit easier by isolating as much of the code as possible into the driver module. This also makes coverage reporting much simpler for additional drivers since they do not need to provide coverage for storage/helper.
Consolidate the CIFS tests into the Posix tests since CIFS is just a special case of the Posix.
Test all storage features in the Posix test so that other storage driver tests do not need to provide coverage for storage/storage.
Remove some dead code in the storage/s3 test.
Currently only two auth methods are supported and a lot of refactoring is required to add a third one.
Do the refactoring now to reduce noise in the commit that adds the third auth method.
Currently link-map only allows links that exist in the backup manifest to be remapped to a new destination.
Allow link-map to create a new link as long as a valid path/file from the backup is referenced.
The local process will retry jobs (e.g. backup file) but after a certain number of failures gives up. Previously, the last error was reported but generally the first error is far more valuable. The last error is likely to be a cascade failure such as the protocol being out of sync.
Report the first error (and stack trace) and append the retry errors to the first error without stack trace information.
Currently errors found during the backup are only available in text output when specifying --set.
Add a flag to backup.info that is available in both the text and json output when --set is not specified. This at least provides the basic info that an error was found in the cluster during the backup, though details are still only available as described above.
These tests run in a container without permissions to mount tempfs, so add an option to ci.pl to not create tempfs. Also add some packages not in the base image.
Make the output consistent even when files are listed in a different order. This is purely for testing purposes, but there is no harm in consistent output.
Found on arm64.
Valgrind complained about uninitialized values on arm64 when comparing the reset prefix, probably because "reset" ended up being larger than the option name: Conditional jump or move depends on uninitialised value(s) at cfgParseOption (parse.c:568).
Coverity complained because it could not verify the size of the string to be copied into optionName, probably because it does not understand the purpose of strSize(): You might overrun the 65-character fixed-size string "optionName" by copying the return value of "strZ" without checking the length.
Use strncpy() even though we have already checked the size and make sure the string is terminated. Keep the size check because searching for truncated option names is not a good idea.
This is not a production bug since the code has not been released yet.
It is safer and more efficient to free memory after each handler completes.
The db command handlers use the server context so update them to use the top context.
This allows the stack trace to be set when an error is received by the protocol, rather than appending it to the message. Now these errors will look no different than any other error and the stack trace will be reported in the same way.
One immediate benefit is that test.pl --vm-out --log-level-test=debug will work for tests that check expect log results. Previously, the test would error at the first check because the stack trace included in the message would not match the expected log output.
This will allow new links to be added in a future commit. The current implementation is driven by the links that already exist in the manifest, which would make the new use case more complex to implement.
Also, add a more helpful error when a tablespace link is specified.
"error list" makes it clearer that other errors may be reported. For example, if checksum-page is true in the manifest but no checksum-page-error list is provided then the error is in alignment, i.e. the file size is not a multiple of the page size, with allowances made for a valid-looking partial page at the end of the file.
It is still not possible to differentiate between alignment and page checksum errors in the output but this will be addressed in a future commit.
Azurite introduced a breaking change in 8f63964e to use automatically host-style URIs when the endpoint appears to be a multipart hostname.
This option allows the user to configure which style URI will be used, but changing the endpoint might cause breakage if Azurite decides to use a different style. Future changes to Azurite may also cause breakage.
The pack is both more compact and more efficient than a variant.
Also aggregate the page error info in the main process rather than in the filter to allow additional LSN filtering, to be added in a future commit.
The push and pop code was duplicated in four places, so centralize the code into pckTagStackPop() and pckTagStackPush().
Also create a default bottom item for the stack to avoid allocating a list if there will only ever be the default container, which is very common. This avoids the extra time and memory to allocate a list.
Rather than working directly with Buffer types, define a new Pack pseudo-type that represents a Buffer containing a pack. This makes it clearer that a pack is being stored and allows stronger typing.
The Pack type is more compact and flexible than the Variant type. The Pack type also allows binary data to be stored, which is useful for transferring the passphrase in the CipherBlock filter.
The primary purpose is to allow more (and more complex) result data to be returned efficiently from the PageChecksum filter. For now the PageChecksum filter still returns the original Variant. Converting the result data will be the subject of a future commit.
Also convert filter types to StringId.
Using UNCONSTIFY() is potentially dangerous since the buffer is modified while calculating the checksum, even though the page is reverted to the original state. Instead make a copy to ensure that the original data is never modified.
This requires the logic to be shuffled a bit since the copy cannot be made until we are sure the page is complete.
Command-line help is now generated at build time so it does not need to be committed. This reduces churn on commits that add configuration and/or update the help.
Since churn is no longer an issue, help.auto.c is bzip2 compressed to save space in the binary.
The Perl config parser (Data.pm) has been moved to doc/lib since the Perl build path is no longer required.
Likewise doc/xml/reference.xml has been moved to src/build/help/help.xml since it is required at build time.
Linefeeds were originally used in the place of <p> tags to denote a paragraph. While much of the linefeed usage has been replaced over time, there were many places where it was still being used, especially in reference.xml. This made it difficult to get consistent formatting across different output types. In particular there were formatting issues in the command-line help because it is harder to audit than HTML or PDF.
Replace linefeed formatting with proper <p> tags to make formatting more consistent.
Remove double spaces in all text where <p> tags were added since it does not add churn.
Update all <ul>/<ol>/<li> tags to the more general <list>/<list-item> tags.
Add a few missing periods.
